Is there really moisture in the export data? Macro of investment promotion: the export growth rate in the whole year is likely to be positive, and the export growth rate will show a trend of "first de

  Core view


  Under the trend of global economic slowdown, China’s exports exceeded market expectations for two consecutive months, and the market gradually questioned the authenticity of export data. Does the export growth rate exceed expectations mean that the export data is really wet? In other words, is there really no micro-foundation for the export data in March and April? This paper attempts to answer the above questions from multiple angles and state a more objective export view on the basis of multi-dimensional analysis..


  The main reason for the high growth rate in March and April is by no means from false reports.Judging from the export "counterfeiting" incident announced in previous years, even excluding the conventional false data, the cumulative export amount from January to April this year was as high as more than 7630 billion yuan, and the cumulative export growth rate was about 10%, which was only 0.5 percentage points lower than the cumulative export growth rate announced by the General Administration of Customs.


  Compared with industrial export delivery value, the export volume is more representative of the real export. In March and April this year, the growth rate of export delivery value and the total export volume showed a big deviation, but this is not evidence of false export data.1) The definitions of export delivery value and total export are quite different; 2) From a long period of time, the growth rate of export delivery value and the growth rate of total exports are similar, but for a short period of time, it is not uncommon for them to deviate from each other. In many months, the growth rate of total exports is higher than that of export delivery value. 3) Compared with export delivery value, the monthly growth rate of export volume has obviously changed, which is mainly caused by the statistical method of export volume. 4) It can also be seen from the export sub-items and PMI indicators that the export in March and April did not mainly depend on the industrial enterprises on the regulations.


  Does the deviation of import and export growth rate beyond market expectations mean that the authenticity of export data is suspicious?The main commodity structure of China’s import and export is quite different. In the case of PPI price disturbance, the growth rate of import and export often deviates, not only in March and April. Not only is there a divergence in the growth rate of imports and exports in China, but the growth rates of the United States, Japan, the European Union and South Korea, as the main final consumer goods countries, often deviate, and more often, the growth rate of imports is greater than that of exports, which is mutually evidenced by China’s role as a big producer.


  The difference between the data published by the importing country and the data published by the importing country may be more due to statistical standards, re-export trade of some products and other factors than false reporting.1) China’s exports to Singapore and Vietnam are obviously larger than the imports from China announced by the other side, which is mainly due to the existence of entrepot trade. 2) The amount of imports from China announced by the United States and the European Union is also different from the amount of trade exported to the United States and the European Union by China. In addition to the conventional factors such as differences in statistical standards, time differences and entrepot trade, China is also a big country of final consumer goods. In recent years,’s exports to the United States-the United States imports from China and China exports to the European Union-the European Union imports from China are not the same. The possible reasons are as follows: First, American importers deliberately understate their imports from China to avoid import tariff sanctions. Compared with 2016 and 2017, the difference between China’s exports to the United States and the United States imports from China since 2018 is obvious. Second, compared with other countries, the energy crisis in Europe is more serious in 2022, and the freight for the import and export of goods is obviously higher, which directly causes the EU’s import from China-China’s export to the EU to jump sharply, and other trade exchanges such as South Korea and Europe have the same trend.


  The reason why export performance exceeds market expectations is more the result of diversification of export commodity structure and export destination.1) The high growth rate of export in March was mainly the comprehensive result of the release of the backlog of export orders in the previous period and the effective purchase of orders abroad. In April, export delivery value jumped from-5.4% of the previous value to 0.7%, and exports were more contributed by the shipment value produced in the current period. 2) The structure of China’s main export commodities has obviously gradually moved closer to that before the epidemic, and the advantage of complete industrial chain can indeed enable enterprises to switch commodity structures to adapt to global demand in a relatively short period of time. Compared with that before the epidemic, the contribution of automobiles (including chassis) and auto parts to the total export volume has been on the rise, which has also become the main commodity driving export growth. 3) Thanks to China’s active participation in regional trade, expansion of trade network and continuous deepening of economic and trade cooperation with non-European and American countries, the "Belt and Road", ASEAN, Russia and other non-European and American countries have significantly increased the driving force for China’s export growth.


  We believe that the shift in export growth does not mean that the export growth rate will continue to decline this year.Judging from the PMI index published in China and the export base last year, we believe that the export growth rate will change gears continuously from May to July. However, there is a high probability that the annual export growth rate will still be positive, and the export growth rate from May to December will show a trend of "falling first and then rising".


  main body


  One,In the past, there were indeed false reports on export data, but the main reason for the high growth rate in March and April was by no means false reports.


  Just talking about the authenticity of the data, the State Administration of Taxation will announce the punishment of false reporting of export data and tax fraud every year, which shows that there is indeed the possibility of false reporting of export data, but it is untenable to classify the reasons for exceeding expectations in March and April as false reporting.The false export data is more for tax fraud. Since August 2018, the State Administration of Taxation, together with the Ministry of Public Security, the General Administration of Customs, the People’s Bank of China and other departments, has continued to carry out regular work to crack down on tax fraud. In the context of cracking down on export false reports, there are still criminals who falsely report export data through various means. Since the government has not published the amount of tax recovery from export tax fraud in a specific period of time in detail, we might as well calculate from the export "counterfeiting" incident announced in previous years. In April 2022, the State Taxation Bureau announced that since the special action to crack down on illegal tax fraud was launched in August 2018, by the end of March 2022, the tax authorities had recovered 34.6 billion yuan of national tax losses by investigating and dealing with illegal export tax fraud. According to this rough calculation, about 10 billion yuan of export tax rebates were recovered every year. In addition, the proportion of export tax rebate in total exports is basically maintained in the range of 8%-10%. Based on this, the accumulated amount of export false reports in January-April this year is about 34 billion-42.5 billion.Even excluding the conventional false data, the cumulative export amount from January to April this year was as high as more than 7.63 trillion yuan, and the cumulative export growth rate was about 10%, which was only 0.5 percentage points lower than the cumulative export growth rate announced by the General Administration of Customs.


  In addition, at present, there are mainly two ways to falsely report exports: first, the government actively injects water to falsely report; second, enterprises forge export orders to defraud taxes; third, enterprises set up offshore companies or blend trading partners to defraud taxes through the continuous link of "exporting to domestic sales". We speculate that there are four reasons why the probability of large-scale false reporting of export data in March and April is small:


  1) In March this year, the cumulative amount of export tax rebate announced by the Ministry of Finance was 553.1 billion yuan, which was significantly higher than last year’s 497.1 billion yuan. It is worth noting that the Notice of the State Council on Issues Related to Improving the Burden Mechanism of Export Tax Refund shows that since January 1, 2015, all export tax rebates (including VAT refund for export goods and VAT refund for business tax) will be borne by the central government, and the export tax rebate base originally borne by local governments in 2014 will be paid to the central government in a fixed amount. If local customs or governments cheat taxes by falsely reporting export data, they need to forge bills in multiple links. Unless the central government is willing to subsidize local governments in disguise in this way, it is difficult to escape the examination.


  2) As mentioned earlier, even in the stricter export "counterfeiting" supervision, some enterprises still cheat tax refund by forging export orders, but there is no reason for enterprises to choose to focus on a large number of false reports in March and April, especially at present, they are in the downward period of exports, and the false reports of export orders of micro-enterprises are more likely to be suspected.


  3) Under the background that the full invoice pilot is gradually launched and the fourth phase of golden tax is about to be launched, the tax collection and management system has gradually changed from "managing tax by votes" to "managing tax by numbers", that is, relying on big data for tax governance. Under stricter supervision, the difficulty of export tax fraud has greatly increased.


  4) In addition to falsifying data, another common tax fraud method at this stage is "export to domestic sales", that is, setting up offshore companies or blending trading partners, exporting A goods abroad at a high price, and then importing A goods into China at a low price, thus earning the difference between export tax rebate and customs duties. Generally speaking, this method is not easy for micro enterprises to find, but from the breakdown data of commodities, we can see that among the main commodity structures of import and export, only the import prices of integrated circuits and refined oil in April are significantly lower than the export prices, and because the growth rate of import and export of integrated circuits is less than zero, even if there is tax fraud, it cannot be the main driving force for the overall export growth rate to exceed expectations. The difference between the import and export prices of refined oil products is mainly due to the downward trend of crude oil prices, which is far from the export tax fraud. Except for integrated circuits and refined oil products, the export prices of other commodities are often lower than the import prices, so the argument that a large number of export growth rates are pushed up by "exporting to domestic sales" is not established.

  Second,Compared with industrial export delivery value, the export value is more representative of real export.


  When observing exports, the market tends to pay more attention to two indicators: export delivery value and total exports. In March and April this year, the export growth rate of these two indicators showed a big deviation, and we don’t think this can be used as evidence to suspect that the export data is false.


  1) The definitions of export delivery value and total exports are different.Specifically: First, the reporting period is different. export delivery value is the value of products produced in this period, handed over to foreign trade management departments or self-export in this period, while the total export value is the total value of products exported in this period, not necessarily produced in this period; Second, the statistical scope is different. export delivery value is a product (both local and foreign) produced by industrial enterprises and handed over to foreign trade management departments. The total export value is the value of products exported by all foreign trade management units and industrial enterprises. It is worth noting that some products included in export delivery value may be sold at home after being traded by foreign trade management departments, thus not being exported; Third, the calculation method is different. export delivery value only calculates the processing fee for the products processed with imported materials, while the total export amount is calculated at the full price of the exported products. Fourth, the prices are different. The products handed over to the foreign trade management department in export delivery value are calculated according to the purchase price of the foreign trade management department, and the total export amount is calculated according to the FOB price.


  2) From a long period of time, the growth rate of export delivery value and the growth rate of total exports are similar, but in a short period of time, it is not uncommon for them to deviate from each other. In many months, the growth rate of total exports is higher than that of export delivery value.Compared with the total export volume, export delivery value’s statistical scope is smaller and it doesn’t necessarily include the completed export. Therefore, in academic research, the indicator of export delivery value is often used to examine whether the micro participates in the export, and the specific transaction behavior to measure the overall export still uses the export volume.


  3) Compared with export delivery value, the monthly growth rate of export volume has obviously changed, which is mainly caused by the statistical method of export volume.The statistical process of import and export data of customs goods is extremely "microscopic". When the import and export goods pass through the customs, the specific consignor or consignee must declare the documents to the customs, and the customs declaration will list all kinds of basic information of the goods (such as quantity, amount, destination and other information). After obtaining these customs declarations, the customs will screen out the customs declaration data that meet the statistical conditions, and directly calculate other sub-items such as import and export data and commodity structure on this basis. In the whole process, the customs mainly plays the role of statistics, and does not need other data to calculate. In other words, the data on the customs declaration submitted by the customs will directly enter the customs database and become the basic data of the customs import and export accounting, which is also doomed to a large monthly fluctuation of export data.


  Is there any moisture in the export data?


  In addition, it can be seen from the export sub-items and PMI indicators that the exports in March and April did not mainly depend on the regulated industrial enterprises.According to the export data by enterprise type, compared with state-owned enterprises, collective enterprises and foreign-invested enterprises, the cumulative export of other types of enterprises (mainly private enterprises) rebounded significantly in March compared with the same period of last year. From the index of PMI new export orders, the increase of PMI new export orders of small enterprises was the most obvious in January and February, and once surpassed that of large enterprises in February. Small enterprises other than industrial enterprises are still an important force to drive exports. This can also explain to a certain extent that it is not surprising that export delivery value and the export volume deviated in March and April.

  Is there any moisture in the export data?


  Third,Does the deviation of import and export growth rate beyond market expectations mean that the authenticity of export data is suspicious?


  At present, China is still a major producer in the world, and the growth rates of imports and exports are synchronized in most of the time. However, because of the great differences in the structure of major commodities of imports and exports, in the case of PPI price disturbance, the growth rates of imports and exports often deviate, not only in March and April.When PPI is at a low level year-on-year, "price" has a great drag on the total import volume, and the export growth rate is often significantly higher than the import growth rate; On the contrary, when PPI is at a high level, "price" becomes the main pulling item of total imports, and the growth rate of imports is obviously higher than that of exports. At present, PPI is at a low point in the historical quantile, so it is natural that the export growth rate is greater than the import growth rate.


  In fact, it is not only our country that the growth rate of import and export deviates, but also the United States, Japan, the European Union and South Korea, which are the main final consumer goods countries, often deviate from each other. More often, the growth rate of imports is greater than that of exports, which is mutually evidenced by China’s role as a big producer.

  Is there any moisture in the export data?


  Fourth,The difference between the data published by the importing country and the data published by the importing country may be more due to statistical standards, re-export trade of some products and other factors than false reporting.


  Because we use the total amount of FOB goods for export statistics, and the total amount of FOB goods or CIF goods for import statistics for export destinations from China, there is a gap between the two, such as freight and other expenses. Generally speaking, the total amount of China’s exports to export destinations should be less than the total amount of China’s imports from export destinations, but this is not the case.


  China’s exports to Singapore and Vietnam are obviously larger than the imports from China announced by the other side, which is mainly due to the existence of entrepot trade.From the perspective of specific commodities, the difference between China and Singapore is mainly contributed by plastic products, clothing and its accessories, luggage and similar containers, furniture and its parts in labor-intensive products, household appliances, auto parts, lamps and general machinery and equipment in mechanical and electrical products, but this phenomenon does not exist in other commodities, especially high-tech commodities. The difference between China and Vietnam is mainly contributed by plastic products and textile yarns, fabrics and their products in labor-intensive products. In 2021, the total statistical difference between the two types of goods is 5.5 billion US dollars, accounting for 69% of the statistical difference of labor-intensive products in 2021.


  In addition, as important countries of final consumer goods, the amount of imports from China announced by the United States and the European Union is also different from the amount of trade exported to two countries or regions by China, which is mainly caused by many factors such as statistical standards, time differences, transportation costs and tariff sanctions.From the historical data, with the end of 2019 as the dividing point, since 2020, the difference between China’s exports to the United States and the United States’ imports from China has turned from negative to positive. From the perspective of commodities, it is mainly contributed by labor-intensive plastic products, furniture and its parts, clothing and its accessories, lamps and lighting devices and their parts in electromechanical commodities and household appliances. On the contrary, the difference between China’s exports to the EU and the EU’s imports from China has been in the normal fluctuation range of positive and negative for a long time, and this difference began to turn negative in 2022. From the perspective of specific commodities, the average export value of other commodities except furniture spare parts is smaller than the EU’s imports from China, and this gap has obviously increased since 2022.In addition to the conventional factors such as differences in statistical standards, time differences and entrepot trade, China is also a big country of final consumer goods. In recent years,’s exports to the United States-the United States imports from China and China exports to the European Union-the European Union imports from China are so different. The possible reasons are as follows: First, American importers deliberately understate their imports from China to avoid import tariff sanctions. Compared with 2016 and 2017, the difference between China’s exports to the United States-the United States imports from China has shrunk significantly since 2018. Second, compared with other countries, the energy crisis in Europe is more serious in 2022, and the freight for the import and export of goods is obviously higher, which directly causes the EU’s import from China-China’s export to the EU to jump sharply. This phenomenon not only occurs in China-EU trade, but also exists in other trade exchanges such as South Korea and Europe.

  Five,The reason why export performance exceeds market expectations is more the result of diversification of export commodity structure and export destination.


  As previously analyzed, false export report can’t be the main driving force for the high export growth rate in March and April, so what is the main reason why China’s export growth rate has exceeded expectations when the export growth rate of other countries such as South Korea and Vietnam has obviously declined? We think there are the following factors:


  1) The high export growth rate in March was mainly the comprehensive result of the release of the backlog of export orders in the previous period and the successive delivery of overseas orders.We provide two pieces of evidence: First, export delivery value in March (mainly counting the current period) was significantly narrower than that in December 2022, but the year-on-year growth rate was still negative, which indicated that the growth rate of export in March was the common result of the current and previous inventory squeeze; Second, after the liberalization of the epidemic prevention and control policy, many provinces began to organize groups to go abroad to grab orders, which directly led to a rapid increase in PMI new export orders in January and February 2023.Different from March, export delivery value jumped from-5.4% to 0.7% in April, and the export was more contributed by the shipment value produced in the current period.


  2) As we mentioned in previous reports, the supply advantage of China is largely due to the integrity of the industrial chain. The integrity of the industrial chain enables domestic export enterprises to better cope with the changes in the international trade situation than other countries. We have counted the data of major export commodities since 2017. Compared with before the epidemic, the contribution of plastic products, textile yarns, fabrics and their products, shoes and boots, ceramic products, toys, automatic data processing equipment and its parts, mobile phones, audio equipment and its parts, integrated circuits, medical instruments and instruments to the overall export volume increased greatly during the epidemic. On the contrary, the contribution of agricultural products, refined oil, luggage and similar containers, steel products, wrought aluminum and aluminum products, and general machinery and equipment to the overall export volume has been significantly reduced.According to the export data of the last four months, the structure of China’s main export commodities has obviously gradually moved closer to that before the epidemic, and the advantages of complete industrial chain can indeed enable enterprises to switch commodity structures to adapt to global demand in a short time. It is worth noting that compared with before the epidemic, the contribution of automobiles (including chassis) and auto parts to the total export volume has been on the rise, and it has become the main commodity driving the export growth rate.


  3) In addition to the changes in the structure of export commodities, China’s main export destinations are also more diversified.From the historical data, the manufacturing PMI in the euro zone and the manufacturing PMI in the United States are in line with the change trend of China’s export growth rate, which means that the decline of China’s export growth rate in 2023 still largely depends on the degree of economic recession in Europe and America.However, thanks to China’s active participation in regional trade, expansion of trade network and continuous deepening of economic and trade cooperation with non-European and American countries, the "Belt and Road", ASEAN and Russia have significantly increased the driving force for China’s export growth, among which ASEAN, Brazil, Russia, India, South Africa and Indonesia account for an increasing proportion of China’s total exports.As far as the export data in April is concerned, the contribution rates of Russia, ASEAN, South Africa and Brazil to the overall export growth rate are 2.14%, 0.73%, 0.28% and 0.17% respectively.


  Is there any moisture in the export data?


  Is there any moisture in the export data?


  Six,The fact that the export growth rate will shift does not mean that the export growth rate will continue to decline this year.


  We are in "Do you need to shift gears for export growth? It is mentioned in the article that from May to July, the export growth rate will be continuously shifted, but this does not mean that the export growth rate will continue to decline this year.From the indicators published in China, the PMI value of new export orders dropped in April, but this will not immediately lead to a sharp drop in exports in May. According to historical data, PMI new export orders are often about 2-3 months ahead of exports, so the real pressure of export growth is mainly concentrated in June and July. However, due to the high export base in May last year, we believe that the export growth rate in May will be lower than that in April.


  Although compared with last year, the overall export growth rate in the whole year has been set to a downward trend, there is a high probability that the export growth rate in the whole year will still be positive. From May to December, the export growth rate showed a trend of "falling first and then rising".The absolute change of export value and the marginal change of export growth rate cannot escape three key factors: supply, demand and comparative advantage. In 2023, China’s supply advantage still exists, and the latest data released shows that the export share advantage is still better than before the epidemic. The main uncertainty that determines the specific growth rate of exports comes from the overseas demand side. At present, in the context of the global economic slowdown, China’s export commodities and export destinations have good highlights. Although the driving force of American exports to China does show a decreasing trend, the contribution of countries other than the United States to China’s exports should not be underestimated.


  Risk warning:


  The overseas economic recession has exceeded expectations.

Pay attention to the six signs before sudden death.

  Expert introduction:

  Yu Mengyue, chief physician, professor and doctoral supervisor of National Cardiovascular Center and Fuwai Hospital of China Academy of Medical Sciences, member of China Clinical Epidemiology Society and young member of China Public Health Society.

  In recent years, the prevalence of cardiovascular and cerebrovascular diseases is rising, and the incidence of sudden death is getting higher and higher. Many public figures, such as actors Gao Xiumin, Gu Yue and Ma Ji, died of sudden death. The main cause of sudden death is sudden cardiac death, including cardiac arrest or acute heart failure caused by coronary heart disease or other malignant arrhythmia. Among them, sudden death caused by coronary heart disease can account for 80%. In addition, some cerebrovascular diseases can also cause sudden death. Although the sudden death happened suddenly, there are actually traces to follow. People at high risk of cardiovascular and cerebrovascular diseases should pay special attention to several abnormal manifestations to prevent sudden death.

  1. Recently appeared or aggravated chest tightness.

  If you suddenly feel chest tightness after exercise in the near future, rest for a while can relieve it. This phenomenon suggests that you may have coronary heart disease. The sudden symptoms indicate that the atherosclerotic plaque in the coronary artery is still unstable and may rupture at any time, leading to acute myocardial infarction. If you have chest tightness symptoms occasionally in the past, the symptoms will become more frequent and more serious in the near future. It also shows that the plaques that were previously stable are now slightly damaged and will develop into large ones at any time, leading to the occurrence of acute myocardial infarction. In this case, you should go to the hospital as soon as possible and have medication or surgery.

  2. flustered.

  Palpitation is often a subjective feeling of increased heart rate. Irregular increase in heart rate is usually the result of tachyarrhythmia. Most arrhythmias are less dangerous and will not cause sudden death, but if they are frequent ventricular arrhythmias, there is a risk of developing ventricular fibrillation. In addition, palpitation in many elderly people is caused by atrial fibrillation. If atrial fibrillation is accompanied by heart conduction diseases, it is easy to progress to ventricular fibrillation. After a ventricular fibrillation attack, it can lead to death within a few minutes. Therefore, frequent palpitation attacks should also be treated in time.

  3. The heartbeat is too slow.

  The beating of the heart is initiated by specific pacing cells. The poor function of pacing cells will slow down the beating rate of the heart and even lead to cardiac arrest in severe cases. Pacing cell function will gradually deteriorate with age. With the continuous improvement of life expectancy in China, the proportion of elderly people over 80 years old is also increasing, and the pacemaker cell function of this group will gradually deteriorate and the heart rate will slow down. Older people usually have less activity, and a slower heart rate can also maintain normal life, so it is often ignored. The elderly should regularly monitor blood pressure and heart rate. If the heart rate is less than 50 times and the blood pressure becomes low, it is easy to have long-term cardiac arrest and lead to sudden death.

  4. syncope.

  Syncope is an important precursor of sudden death, and most syncope is caused by the sudden slowdown or stop of heartbeat, resulting in insufficient blood supply to the brain. Common causes include sinus node disease, atrioventricular block, and hypertonia of vagus nerve. Sometimes syncope can recover after a few seconds, and if it can’t recover, it will cause sudden death. Therefore, we should be very vigilant after unexplained syncope, find out the cause as soon as possible, and prevent the next syncope or even sudden death.

  5. Unexplained fatigue.

  Sudden death is not a patent for the elderly, but also happens to young people. It is normal for many young people to suffer from heavy work pressure and fatigue. However, if there is unexplained fatigue and fatigue, or accompanied by chest tightness and edema, you should be alert to the occurrence of sudden death, which may be caused by myocarditis or cardiomyopathy. Myocarditis is more common among young people, usually after 1~2 weeks of catching a cold, with symptoms such as fatigue, chest tightness and fatigue, which can easily cause acute heart failure. In this case, heavy physical activity and bed rest should be strictly prohibited. Cardiomyopathy is mostly hereditary disease, which is not easy to detect in the early stage. When symptoms appear, irreversible changes in myocardial structure have occurred, such as cardiac enlargement and myocardial hypertrophy, which are very likely to lead to sudden death. Therefore, when there is unexplained fatigue and chest tightness, we should be highly alert to myocarditis and cardiomyopathy.

  6. Black eyes and numbness of limbs.

  Stroke is also an important cause of sudden death. Some strokes have a sudden onset, and limb paralysis and high blood pressure will occur within a few minutes. In this case, patients can save their lives if they see a doctor in time. However, some strokes have a slow onset and only mild symptoms in the early stage, and patients don’t care. Once it progresses, it may lead to sudden death, so you need to pay more attention. Especially in patients with hypertension, coronary heart disease or atrial fibrillation, the incidence of stroke is several times higher than that of the general population. If you can’t see things on one side, your limbs are numb and weak, or you walk unsteadily and feel like stepping on cotton, you should be alert to the occurrence of stroke and see a doctor in time. Early identification can often achieve better curative effect.

  In order to find the above-mentioned precursors of sudden death, we need to be alert to physical discomfort at all times, respond quickly when things happen, and seek medical advice in time. ▲

  At the fork of Zheng Xinyi’s fate, Li Yongjie, his attending doctor and director of Beijing Institute of Functional Neurosurgery, stood there with a smile — — It was he and his team who realized the dream that "China Forrest Gump" had broken one place through surgery.

  July 12th is the 20th anniversary of the first "cell knife" operation in China. Xinhua Daily Telegraph reporter entered the organization that has become the largest number of brain pacemakers implanted in the world for 10 consecutive years — — Xuanwu hospital Institute of Functional Neurosurgery and Beijing Institute of Functional Neurosurgery of Capital Medical University.

  He was admitted to Peking University in 1979, studied abroad in 1994, and returned to China 20 years ago to establish the Beijing Institute of Functional Neurosurgery. A few years ago, he began to explore the society to run doctors and set up outpatient departments to help more people see and be optimistic about the disease … … In the recent 40 years, Li Yongjie’s fate has been closely linked with the changes of a discipline and an era.

  Open your eyes and see the world:

  From "the first person in cell knife" to "a seed"

  The human brain is one of the most amazing and complicated substances in the world. To move a "knife" on the brain requires not only courage, but also "real kung fu".

  The operation that Li Yongjie cured Zheng Xinyi was called "Deep Brain Stimulation Operation". Simply put, it is to put electrodes deep in the human brain. The scientific principle is that the dyskinesia of human body is caused by pathological changes in some brain cells, and their symptoms can be controlled and regulated by electrical stimulation of the pathological cells.

  Such an operation sounds simple, but in fact, human beings didn’t realize the relationship between human brain and consciousness and behavior until the end of the 19th century. The accurate treatment of brain tissue by surgery can be traced back to the emergence of stereotactic technology in 1947 — — At that time, the disease targeted by this technology was Parkinson’s disease, which was called "immortal cancer".

  At first, the patient’s hands and feet showed rhythmic tremor, slow movement, difficulty in tying shoelaces and buttons, and difficulty in putting on and taking off shoes and socks. After 5 to 15 years of illness, he gradually lost his mobility … … Parkinson’s disease is a slowly progressive disease, which mainly occurs in middle-aged and elderly people. Muhammad Ali and mathematician Chen Jingrun all suffered from this disease.

  In 1994, Li Yongjie, who had just gone abroad for postdoctoral studies, first came into contact with the cutting-edge microelectrode-guided stereotactic neurosurgery. This is a technique to stop the patient’s body tremor by destroying the "tremor cells" in the brain, which is vividly called "cell knife".

  As a neuromodulation surgery, it uses stereotactic method to locate accurately, implants stimulation electrodes in the human brain, and controls the stimulation parameters of the electrodes in the brain through the remote control device in vitro, so as to control and improve the patient’s disease symptoms. It is the most successful case for human beings to realize the dream of "brain-computer dialogue".

  "This kind of deep brain stimulator, also known as brain pacemaker, is the most advanced technical means for the treatment of functional encephalopathy in the international medical community since the beginning of the 21 ST century, among which the treatment of Parkinson’s disease patients is the most mature and common." Today, Li Yongjie still remembers the shock of that moment.

  After the patient who was treated in the operating room was accurately located in the skull, a very thin electrode went deep into her brain to find the abnormal cells, and then it was "destroyed" by radio frequency heating. Within a few seconds, the violent tremor of the patient’s right hand disappeared, and her tears welled up in her eyes: "Oh, my God, it’s stopped for 10 years … …”

  "The whole world seems to be silent, and I can only hear the voice in my heart: I must master this technology!" Li Yongjie, 57, will never forget the moment when he decided his future academic direction and even his life destiny.

  At that time, this advanced surgical technique was still a blank in China, and doctors also called Parkinson’s disease "tremor paralysis". Li Yongjie, who has been a doctor of medicine in China for several years, knows very well that there are tens of millions of patients with nervous system functional diseases like Parkinson’s disease in China, and high-level brain surgery intervention is urgently needed.

  After graduating as a postdoctoral fellow, Li Yongjie did not hesitate to join the world-renowned stereotactic neurosurgery — — The medical center of Linda University in Rome has mastered all the techniques of "cell knife" in only two years.

  "There are so many patients in China, I want to go back to China and bring back the technology I have learned!" Li Yongjie’s inner voice rang again. Comfortable life, clean environment, American green card … … Nothing can stop him from returning to China.

  "I left without hesitation." Li Yongjie said firmly.

  On July 12th, 1998, the first "cell knife" operation in China began in xuanwu hospital. Li Yongjie, who returned from school, is a surgeon, anesthesiologist, radiologist and nurse … … Because no one knows how this "sophisticated" operation is done, he needs to personally control every link.

  Heading, taking the patient to the nuclear magnetic room for brain scanning, positioning the surgical target, calculating the target position, craniotomy, drilling, inserting a very fine puncture needle to reach the target position, and inserting a microelectrode &hellip along the needle track; … Unconsciously, eight hours passed, and Li Yongjie, who was immersed in it, didn’t feel it at all. The doctors and nurses on the sidelines saw that the error of electrode positioning was less than 1 mm, and the patient’s trembling hand gradually stopped during the operation.

  "The human brain is a black box. Stereotactic technology is a bit like GPS and must be accurate to the millimeter." Li Yongjie said.

  Functional Neurosurgery Newsletter is a peer-to-peer exchange publication run by the Institute. The cover of the 10th issue published in April 2012 is a picture of Swiss national hero william tell aiming at an apple on his son’s head not far away under the oppression of colonists.

  "Through the distant time and space, we are capturing William’s breath in the picture, pulse diagnosis’s pulse, and appreciate each other’s heart is sympathetic." Li Yongjie wrote in the article "Courage and Responsibility Create Glory" on the front page of the magazine, "Because our profession is a doctor who saves lives, and the disease is ‘ Magic ’ The doctor is a bow and arrow maker. Facing the eyes of patients seeking help or even despair, facing the challenges of difficult and complicated diseases, and facing the medical risks and sociological risks brought by treatment, we are tested and challenged every day. This not only requires our confidence in our own knowledge and skills, but also challenges our courage and responsibility. "

  Neurosurgery, especially stereotactic surgery, is like shooting an apple with a bow.

  "This requires a high degree of accuracy, and no mistakes are allowed, so as to ensure that patients are safe, and ‘ Shoot ’ The disease is invisible. " Li Yongjie said.

  "It feels amazing." Lu Xiaoli, a doctor who witnessed the whole operation, remembers that after the success of the operation, more and more patients came here. By the end of 1998, Li Yongjie’s team had been able to perform dozens of "cell knife" operations every month, and a set of scientific operation standard procedures were established, and the operation time was shortened to an average of two hours.

  "I am just a seed, bringing this technology back to China and blossoming everywhere." Li Yongjie, who is known as the "first person of cell knife", said modestly that if he has made any contribution, it is to make the stereotactic technology develop more finely and safely in China.

  Parkinson’s disease is the most common type of dyskinesia. Epidemiological statistics show that there are 2 million patients in China, accounting for 40% of the total number of patients in the world. Due to the aging of the population, the incidence of Parkinson’s disease is still increasing, and it has become one of the common diseases in the nervous system of middle-aged and elderly people.

  In 1817, the British doctor Parkinson confirmed Parkinson’s disease in his book "On Tremor Paralysis", and then the international medical community named the disease after him.

  "This year is 201 years since Parkinson’s disease was confirmed." Li Yongjie said, "Before I went abroad, the name Parkinson’s disease had been used abroad for more than 100 years, and this disease was still called ‘ Tremor paralysis ’ . Now the country is also called Parkinson’s disease, which is the result of everyone opening their eyes to see the world. "

  The pioneering and exploration of Beijing Institute of Functional Neurosurgery has made countless patients see hope.

  As of July 12, 2018, in the past 20 years, Beijing Institute of Functional Neurosurgery has performed stereotactic surgery for 6,690 patients with dyskinesia, involving 13 types of functional neurosurgical diseases: Parkinson’s disease accounts for more than 3/4, followed by primary tremor (10.87%) and dystonia (7.17%), and other dyskinesia only accounts for 5.74%— — Include cerebral palsy, TIC disorder, Parkinson’s superposition syndrome, voluntary movement’s disease, chorea, etc.

  "At the beginning of returning to China for three or five years, we were fighting alone. In the last five or six years, hospitals and universities everywhere can’t wait to develop functional neurosurgery. " Li Yongjie said.

  The brave are invincible:

  Let functional neurosurgery blossom in China in 20 years.

  Starting from the first "cell knife" operation 20 years ago, China has established a multi-level and all-round discipline framework of functional neurosurgery, which focuses on dyskinesia, epilepsy surgery and pain, and spreads to neuromuscular spasm and psychosurgery.

  Li Yongjie’s "battlefield for one person" has also become a "team competition".

  At that time, xuanwu hospital established the Beijing Institute of Functional Neurosurgery because of his return, which is the first clinical treatment and scientific research institution in the field of functional neurosurgery in China. Since 2009, it has become the world’s largest "Deep Brain Stimulation Treatment Center", and the number of brain pacemakers implanted has been the first in the world for 10 consecutive years.

  "This is the result of a team competition, but the high technology of the brain stimulator comes from the other side of the ocean. No matter how big the implant is, it just follows, not leads." Li Yongjie is very sober. "It’s my real mission to return to China to start a business, not to be a flash in the pan, but to develop steadily."

  Faced with the huge medical demand and the blank field of functional neurosurgery in China at that time, the doctor with elegant appearance and slow speech showed the well-known word "courage" and shouldered the two burdens of talent training and discipline construction.

  It is hard to imagine that when Li Yongjie cured Zheng Xinyi’s "spastic cerebral palsy" in 2010, brain electrode implantation was still in the early clinical exploration in the world. This means that his frontier exploration will inevitably have the risk of failure.

  Li Yongjie admits that although he "cherishes feathers", he wants to be a good brain surgeon, "focusing on intelligence in the short term, ability in the medium term and responsibility in the long term". To this end, he set a rule for surgery: "I will do the most difficult, latest and risky surgery!"

  Once, Li Yongjie met an epileptic with a particularly complicated condition. After she failed in an operation in a foreign country, she was introduced to see a doctor by a medical elder. But after an impeccable craniotomy, her condition actually relapsed. This means that the previous judgment of the lesion is likely to be wrong.

  When Li Yongjie was called to the ward by his colleagues, what he saw was such a scene: the patient’s mother was sitting on the windowsill, desperate. Based on careful observation, Li Yongjie made a decisive second craniotomy and confirmed that the real lesion was in the parietal lobe of the brain, less than 2 cm away from the motor cortex of the brain.

  Do you want to do the third craniotomy? Who will do it? Li Yongjie did not hesitate to stand before the operating table. He carefully removed the focus cells as big as the fingernail, avoiding the dangerous motor cortex injury.

  "The patient is only 16 years old. If he is paralyzed by surgery, the young doctor may not be able to bear this huge psychological burden, then I will come." He smiled and recalled as if those thrilling "moments of life and death" were as usual.

  Dr. Lu Xiaoli, who has been following him, commented that he was "not angry and arrogant" — — "When he is around, everyone relies on him from the heart, which is the personality charm of Professor Li".

  He is honest with others.

  "If you don’t look at it, as long as I pick it up, I must be responsible for the patient to the end." Li Yongjie said, "It must be that those who dare to take responsibility make rapid progress, and those who are afraid of accidents make slow progress. In the end, it is better than taking responsibility."

  "Teacher Li often tells us that being a good doctor is the first priority. For diseases that can be cured, the treatment should be serious and accurate, and the best treatment plan should be discussed for difficult cases. For diseases that have no treatment for the time being, patients and their families should correctly understand and face the disease positively. ‘ Sometimes it’s healing, often it’s helping, always comforting ’ 。” Zhou Changshuai, a student in Li Yongjie, once quoted this sentence to describe his mentor in an article entitled "The Short Story of big doctor".

  More than 100,000 patients from all over the world were diagnosed and treated, and more than 10,000 cases were treated by surgery … … After 20 years, Li Yongjie has realized his ambition of returning to China: 16 "Xuanwu workshops" for hospitals across the country have trained a high-level "national team" of functional neurosurgery and trained thousands of doctors across the country; Cutting-edge technologies such as "cell knife", deep brain stimulation and endoscopic surgery have been introduced into China, and the number of diseases that can be diagnosed and treated has expanded to more than 30.

  "I am obsessive-compulsive disorder and perfectionist." Li Yongjie said, "Scientific research is a kind of spirit, attitude and method. To treat scientific research as work and work as scientific research, we must understand and clarify, run the spirit of scientific research through our work, and constantly expand the scope of application of technology."

  Someone asked Li Yongjie, "Aren’t you afraid to teach your disciples and starve your master?" He laughed: "I have so many new technologies and fields to learn, how can I have time to think about them?"

  Parkinson’s disease, primary disorder, dystonia, TIC disorder, voluntary movement’s disease, cerebral palsy, myotonia and other motor disorders, various epilepsy diseases, chronic pain such as central pain, peripheral nerve injury pain, cancer pain, visceral pain, soft tissue pain, low back pain, neck and shoulder pain, and neurospinal diseases such as lumbar disc herniation and cervical disc herniation & HELIP; … Experts from Beijing Institute of Functional Neurosurgery have treated or operated on more than 30 diseases recorded in Functional Neurosurgery.

  "In the field of functional neurosurgery, a comprehensive platform for treating diseases like ours can’t be found all over the world." Li Yongjie’s tone is gentle, but he is confident and proud. "In 20 years, I set up a platform for discipline development and brought out a team. Even if I retire, this subject will continue to develop. "

  In the conference room of the Institute of Functional Neurology, picture frames are hung on the wall in order, and each one is longer than the other — — Because this is the annual photo of the Institute.

  "Under the leadership of Director Li, our group photo lasted for 20 years. We are a big family and the team is getting bigger and bigger, so the group photos are getting longer and longer. " Lu Xiaoli said.

  Looking back on the 40 years of reform and opening-up, Li Yongjie was filled with emotion: "We have caught up with the era of reform and opening-up, which is the best and fastest period of economic, social, knowledge, science and technology development in China for thousands of years. From an ignorant teenager to a medical expert and academic leader, from an entrepreneur with dreams to the ideal landing and rooting, my growth and harvest are all thanks to the times. "

  "From an idiotic dream to a dream come true, I am more like the child running on the beautiful beach. Among the sea goods surrounded by waves on the beach, I am delighted to find several colorful shells … … Looking around, there are so many such children! "

  Ten years ago, Li Yongjie wrote this passage with emotion, which is meaningful today.

  Always on the road:

  A restless scientist

  Sharpen a sword in 20 years.

  The team of more than 100 people led by Li Yongjie has become the world-famous "China Team" in the field of functional neurosurgery, and ranks among the international "first phalanx" — — Beijing Institute of Functional Neurosurgery was awarded the title of "Clinical Center of Excellence" by international institutions as early as 1999, becoming the only clinical institution in Asia to receive this honor.

  What else does he want?

  "I am a restless person, and I naturally like to do something new and different." There was a childlike look on his face. "I hope to be recognized as a scientist doctor."

  In fact, it was Li Yongjie’s childhood dream to be a scientist, but it was accidental to study medicine.

  In 1960s, he was born in an ordinary family in Datong City, Shanxi Province. In that special time when "sports followed sports", Li Yongjie was a "silent, timid" child because of his family background of "rich peasants", and he was "aged and lonely out of proportion to his age".

  But under his seemingly "juvenile maturity" appearance, there is an interesting and curious soul hidden. He loved natural science since he was a child, and when he was 6 years old, he had a whim to make a perpetual motion machine with water currents and waterwheels. After the Tangshan earthquake, he hung a small hammer with enameled wire and passed through the ring. As long as it shook, it would trigger the ringing of the electric bell. He was very proud of this homemade "seismograph". At the age of 15, he climbed onto the roof to install an antenna, and the self-made "crystal receiver" actually received china national radio’s voice … …

  In 1977, China resumed the national college entrance examination and entered the "scientific spring" with emphasis on education and knowledge.

  "The resumption of the college entrance examination has restored the vitality of the social class." In 1979, Li Yongjie, who won the first prize in Shanxi Physics Competition, gave up the opportunity to attend the university of Shanxi Province without taking the exam and chose to take the college entrance examination, and was admitted to the top 20 in the province. His mother said, "If only our family could have a doctor, you could study medicine", which made him filial and medicine accompany him ever since.

  In 1991, Li Yongjie, who received a doctor’s degree in medicine from Shanxi Medical University and published two English papers in Brain Research magazine, saw the huge gap between domestic and foreign advanced technology. A strong thirst for knowledge made him "desperate" and sold his newly allocated house to study abroad.

  "My growth and harvest are all thanks to the times. If I don’t catch up with the golden age of 40 years of reform and opening up, I may not be able to dominate my own destiny." He said, "Therefore, I firmly believe that my seed will be the home only if it falls on the land of the motherland, and it will grow most vigorously."

  "The door of opportunity opened by reform is getting bigger and bigger, and the chances that individuals can dominate their own destiny are getting higher and higher." Li Yongjie, which chose to return to China, has indeed achieved "the most vigorous growth" — — Under his leadership, Beijing Institute of Functional Neurosurgery keeps track of the latest development of functional encephalopathy in the world, improves technical methods, improves the level of treatment and expands the scope of treatment.

  In March 1999, the Institute of Functional Neurosurgery successfully treated Parkinson’s disease with subthalamic nucleus destruction technology, and in the same year, deep brain stimulation technology (brain pacemaker therapy) was developed to treat Parkinson’s disease.

  In May, 1999, the first operation to treat generalized torsion spasm was successful.

  In the second half of 1999, the first operation to treat spastic torticollis, chorea and Tourette’s syndrome was successful one after another.

  In the new century, after creatively expanding the scope of surgical treatment to other dyskinesia diseases, his team began to pay attention to the work in the field of surgical treatment of epilepsy and pain … …

  "Yongjie’s team has always led the development of functional neurosurgery in China, from treating Parkinson’s disease to epilepsy to pain … …” Professor Yuxi Liu of Shanxi Medical University said.

  In the past three years, the average annual operation volume of Beijing Institute of Functional Surgery was over 1,600, and a team with their own strengths and vitality also grew up — —

  Zhang Guojun and Yu Tao focus on the localization of epileptogenic focus and microsurgical treatment of intractable epilepsy; Hu Yongsheng specializes in surgical treatment and nerve regulation of chronic pain; Zhu Hongwei is good at neurospinal and cranial neuropathy; Li Jianyu has 20 years of experience in surgical treatment of dyskinesia … …

  In September 2017, the Huaxia Conference on Functional Neurosurgery was held in Beijing, and more than 20 top scholars in the world and more than 100 well-known experts in China arrived as scheduled.

  In his speech at the conference, Li Yongjie introduced the summary of the world’s largest surgical cases of dyskinesia completed by the Institute in the past 20 years: a total of 6,467 cases were treated by surgery, and it was also found that the risk of Parkinson’s disease in men was 1.46 times that of women, and the overall dyskinesia was 1.45 times; At the age of onset, half of the patients with Parkinson’s disease developed before the age of 53, and half of them received surgery before the age of 61.

  In the first 10 years after returning to China, Li Yongjie devoted himself to improving the diagnosis and treatment of Parkinson’s disease and epilepsy to the international level, and then he turned his attention to the treatment of chronic pain.

  "The most common and harmful pain is disc herniation. My focus now is how to make it more meticulous and minimally invasive, in line with international concepts and models." He said.

  Exploration is always on the road — —

  "Science, solve ‘ Day ’ The problem; Technology, solve ‘ Land ’ The problem. I am still optimistic about the prospect of surgical treatment of emotional disorders such as major depression, hoping to find that key and open the door to the connection between heaven and earth. " He said.

  Li Yongjie, a member of the Standing Committee of the Beijing Municipal Political Consultative Conference, has repeatedly encouraged and called for the reform of the medical system. He has also done his best: in 2014, he promoted social capital to set up the Beijing Xidian Clinic, so that the advanced national specialized medical model can take root and explore a new path of graded diagnosis and treatment.

  "Medical reform has entered the deep water area, which requires not only the skills of those who bow and arrow ‘ Emboldened ’ It requires the sense of responsibility of those involved in medical reform and the courage and responsibility of reformers. The reform of the medical system is risky, and it is even more risky if the medical system is not reformed. Go on the road with responsibility, courage and responsibility, because we believe that after twists and turns and even dangers, we will eventually reap glory. " Li Yongjie’s words spoke out the common aspiration of the participants in the western clinic.

  "Every discipline has its scientific, systematic and complete requirements and development expectations … … As far as I am concerned, more than 20 years of study, research, practice and teaching experience in the field of functional neurosurgery are even more eager for it. " In 2018, Li Yongjie led the team to compile the lifelong learning and practice into a 1.5-million-word masterpiece Functional Neurosurgery. "The editorial team adheres to the concept of combining theoretical interpretation with clinical practice, and hopes to weave a whole picture in the field of functional neurosurgery with this context, hoping that it will become a classic in the field of functional neurosurgery."

  "Patients with functional diseases of the nervous system account for more than 10% of the total population, and there are tens of millions of people who need interventional therapy. The number of people who can benefit from surgery is conservatively estimated to be as high as 5 million, which is about 10 times that of patients with brain tumors. Such a huge demand for medical services cannot be ignored, and historic opportunities for discipline development should not be missed. " He appealed in the preface.

  In October 2017, Zhu Hongwei and Zhang Jiaxing of Beijing Institute of Functional Neurosurgery participated in an important international academic conference in neurosurgery, and found that this conference "no matter the lecture content or the frontier field display, the function and nerve spine account for nearly half, and everyone is working hard on stereotactic, navigation and artificial intelligence … …”

  "This conference really shows the future development direction of neurosurgery, from which we can see our shortcomings and our status. It is proud that many of the work of the Beijing Institute of Functional Neurosurgery is at the forefront of the world. I believe that in new fields, we will also keep up with the international pace and make our own characteristics in the field of neurospinal surgery. " Zhang Jiaxing said.

  In the face of achievements, Li Yongjie was unusually sober.

  "We let the international advanced technology take root and bear fruit in China, and even ran away with international counterparts in clinic. Of course, there is innovation in this, but deep brain stimulation technology was invented abroad, and we still lack real original inventions. We need to open up new fields and invent new equipment, and start with creativity, research and development, market development and resource integration to establish a complete chain of scientific research and industrial development. " Li Yongjie said, "From quantitative change to qualitative change, this possibility has greatly increased now."

  Li Yongjie revealed that his team is brewing non-invasive surgery. "This is the next step in surgery and treatment, and it will be a big breakthrough. I am optimistic about it."

  On the occasion of Functional Neurosurgery in Fu Zi, it was the time when Alpha Go defeated the top human Weiqi players.

  "The brain has 60 billion to 70 billion brain cells. If you regard them as planets, then the brain is as infinite as the universe." Li Yongjie, who is optimistic about brain-computer interface, said excitedly that if we can join hands with engineers, it may connect human imagination and mobility. "That will open up a new world of functional neurosurgery".

Bacteria in the mouth are quietly "detonating" these eight diseases.

Original rehabilitation magazine

There are hundreds of millions of microorganisms living in our mouth, with nearly 800 species, which together constitute the oral microflora. Like the intestinal flora, the oral microflora is also very diverse. Most of them are resident bacteria that coexist with human beings for a long time. They are generally harmless and even beneficial to human bodies, and they are "good friends" of our bodies. Under normal circumstances, the resident microorganisms in the oral cavity form a stable ecological balance, and once the ecological balance is broken, "good friends" will also become "bad molecules", which will spread to other parts of the body through blood, digestion and breathing, causing or aggravating various serious diseases.

The first type: cardiovascular and cerebrovascular diseases.

The oral cavity is connected with the outside world, which is the gateway for all kinds of microorganisms to enter the body. Streptococcus mutans in oral cavity and Porphyromonas gingivalis are the "culprits" of dental caries and periodontal disease respectively. Periodontal disease not only leads to tooth loosening and falling off, but also is closely related to life-threatening cardiovascular and cerebrovascular diseases such as stroke and myocardial infarction. Scientists have detected common microorganisms in the oral cavity in atherosclerotic plaques of such patients, among which Porphyromonas gingivalis has the largest number, and the more serious periodontal disease is, the larger the plaque area is.

Periodontal bacteria and their harmful metabolites can enter the blood through the broken gums, causing damage to blood vessels, aggravating atherosclerosis and further increasing the risk of stroke and myocardial infarction. Studies have confirmed that the symptoms of cardiovascular and cerebrovascular diseases have also been alleviated after periodontal treatment.

The second type: diabetes

There is a strong two-way relationship between type 2 diabetes and periodontal disease. The increase of inflammatory factors in patients with severe periodontitis interferes with the role of insulin as a "porter" of blood sugar, leading to excess sugar in the blood and causing blood sugar fluctuation, so the risk of developing diabetes in patients with periodontitis is 2~3 times that of normal people.

However, diabetic patients often have dry mouth, and their oral self-cleaning ability decreases, making it easier for germs to breed and multiply; At the same time, the resistance and healing power of gums are weak, and the rising blood sugar will provide more "nutrients" for oral bacteria, which will lead to more serious inflammation. This interaction has formed a vicious circle. Studies have pointed out that perfect periodontal treatment can reduce glycosylated hemoglobin and fasting blood glucose and improve patients’ systemic symptoms.

The third kind: autoimmune diseases.

Autoimmune diseases are a kind of diseases that attack human tissues or organs due to abnormal immune system. They are all serious chronic diseases. Inflammation is the common feature of these diseases, and infection caused by oral pathogenic microorganisms is one of the important causes of autoimmune diseases. For example, Porphyromonas gingivalis is related to the occurrence and development of rheumatoid arthritis, inflammatory bowel disease and systemic lupus erythematosus. Candida albicans is closely related to Sjogren’s syndrome.

Imagine that if the "bad molecules" in the mouth are very active, the immune system will always be in a state of "high alert", and inflammation in the body will persist, which will lead to systemic symptoms in the long run. If you have a related disease, but the condition is not controlled as expected, you may have to pay attention to whether the flora in your mouth is disordered.

The fourth kind: digestive system diseases.

The oral cavity is the initial part of the digestive tract, and Helicobacter pylori (Hp) in the oral cavity is also related to the occurrence of gastrointestinal diseases. Oral cavity may become the repository of Hp, increasing the risk of infection, and then causing gastritis, gastric ulcer and other diseases; Hp was also found to be related to Hashimoto’s thyroiditis.

Fifth: Alzheimer’s disease.

Alzheimer’s disease, commonly known as "Alzheimer’s disease". With the decline of immunity, the decrease of saliva and the need to wear dentures in the elderly, the oral microecology is prone to disorder, which is characterized by the increase of periodontal bacteria and the higher number of fungi than young people.

Periodontal pathogens and their toxic products can invade the brain through blood circulation and neural pathways, colonize in the brain, release toxic substances to cause neuronal apoptosis, and accelerate the progress of Alzheimer’s disease; Fungal infection can not only cause oral mucosal lesions, but also destroy the blood-brain barrier of the elderly and damage the central nervous system. In addition, herpes simplex virus and cytomegalovirus, which are common in oral cavity, have also been found to be related to cognitive and memory disorders.

Sixth: respiratory diseases

As the front entrance of respiratory tract, the microbial status of oral cavity directly affects the health of respiratory system. Bacteria and secretions in the mouth may be inhaled into the respiratory tract, blocking the smaller bronchi and increasing the risk of pneumonia and bronchitis, especially for the elderly and immunocompromised people. Studies have shown that people with poor oral hygiene are about 30% more likely to suffer from chronic obstructive pulmonary disease (COPD) than those with healthy oral hygiene.

Seventh: pregnancy complications

Oral health has an important impact on pregnancy and newborn health. During pregnancy, due to the rapid changes in hormone levels, pregnant women’s gums are more prone to swelling and inflammation, and 60%~70% of pregnant women worldwide suffer from pregnancy gingivitis. Poor oral health may also increase the risk of complications such as gestational diabetes mellitus and preeclampsia.

At the same time, pregnant women with severe periodontitis, their periodontal pathogens can break through the gums and directly act on the placenta and uterine cavity with blood, stimulating uterine contraction, resulting in premature delivery and low birth weight, which is 7.5 times higher than that of healthy pregnant women, which is greater than the impact of smoking and drinking on the fetus.

Eighth: cancer

Oral microorganisms are closely related to the occurrence and development of various tumors. At present, it is known that the imbalance of oral flora, candida albicans, human papillomavirus infection and other factors will promote the course of oral squamous cell carcinoma, and many typical oral "bad molecules" will become "accomplices" of cancer, especially digestive system tumors, such as Fossetta and Porphyromonas gingivalis, which are related to esophageal cancer. Fusobacterium nucleatum can enhance the viability of cancer cells and can grow in colorectal cancer. If it exists, the survival rate and prognosis of colorectal cancer patients are poor.

Link: Tips for maintaining oral health

Oral cavity is the starting point and gateway of human defense, and it is very important to maintain the ecological balance of oral microflora. Only with a good mouth can you be healthy. Let the "good friends" in the mouth guard the first line of defense of health for us.

1. Use a soft-bristled toothbrush, brush your teeth at least twice a day for 3 minutes each time, and use dental floss and a tooth washer to clean every tooth surface and gap. It is more important to brush your teeth before going to bed at night. Patients with removable dentures, fixed dentures and dental implants need to be cleaned more carefully because dentures are easy to hide evil people and shelter evil people.

2. Pap brushing method is used for permanent teeth, and circular arc method can be used for deciduous teeth. On the basis of children’s insistence on brushing their teeth, parents should also help and supervise their children to brush their teeth.

3. Eat more foods rich in protein, minerals and vitamins, eat less high-sugar foods and rinse your mouth after eating. The mouthwash containing bactericide will lead to microbial imbalance, so it needs to be used according to the doctor’s advice.

4. Avoid smoking and drinking, use less antibiotics, develop good habits of work and rest and defecation, and stay up late less to prevent disturbing the flora.

5. Conduct oral examination once every six months to find and actively treat oral diseases as soon as possible; Wash your teeth regularly and give them a thorough cleaning.

Original title: "Bacteria in the mouth are quietly" detonating "these 8 diseases"

Read the original text

Adult education after 1990s is all in domestic cartoons.

In less than a month, the first batch of 90′ s will be in Grade Three.

Under the pressure of 2020, the post-90 s were forced to go to several hot searches.

How miserable is it after 90? The flesh is bulging, the wallet is empty, and the hair is bald.

But I think these tragedies are nothing. After all, we were abused from childhood.

Recently, I found that cartoons, which should be good memories of childhood, are abusive in the memories of our generation.

90% of the first tears after 90s were dedicated to domestic cartoons..

When the editorial department was discussing which animation was the most cruel, I thought of Beckham’s Wandering.

Just talking about this ancient animation in 1999, my colleague quickly interrupted:

"Stop it, 20 years later, I just want to cry when I hear the words’ Beckham’s Wandering’. "

Not only her, but also netizens feel that this animation is too abusive.

Some people were unwilling to cry alone when they were young, so they took Beckham’s Wandering Story to the kindergarten to share with other children, and they wanted to cry together.

What does such a cruel animation say?

A kitten named Beckham accidentally separated from her mother, grew up after many hardships, and finally returned to the city to find her mother.

The opening episode is the worst nightmare of countless children: being forced to be separated from their mothers.

Beckham was picked up and sent away by Xiong Haizi, and the cat mother was anxious to chase the truck all the way.

But how can a cat catch up with a truck?

Mother cat was thrown out of the car, covered in injuries, watching the truck go away, crying and shouting "Beckham".

People driving by almost ran into it and scolded, "What a crazy cat."

No one understands that the cat has just lost its own child.

And just this scene of a cat mother chasing a car is enough for me to cry.

I remember going to the convenience store to buy things when I was a child. My mother always waited for me at the door. Once I didn’t see my mother after I came out. She was not here for a minute, so I couldn’t help crying. My mother coaxed me all afternoon.

Later, for a long time, I had the same nightmare again and again.

In my dream, my mother kept going forward. I shouted at her desperately but didn’t look back. I tried to run and catch up, but I couldn’t catch up.

At the end of every dream, I wake up crying.

So every time I look at Beckham, I think of the fear of leaving my mother when I was a child, and the feeling of being abandoned, and I will automatically substitute myself into Beckham.

Beckham was laughed at for being "screaming like a mouse" because he was born thin, so he always insisted on self-reliance and said "I can do it" in a milk voice.

It wandered alone in the wild, being chased by wolves and being rained, and it became stronger after repeated tempering.

But all the strength collapsed when the mother dog asked him, "Why don’t you go home?".

Beckham couldn’t help it any longer, threw himself into the dog’s mother’s arms and cried, "Mom can’t find it, I was taken away."

As I get older, I’m getting more and more afraid to watch this scene of heart abuse.

Probably my love for the cat owner began with Beckham.

Beckham’s Wandering Story is the earliest enlightenment animation about affection I have ever seen. Although its plot is not complicated, it accurately captures the pain point of children’s "fear of being separated from their parents" and describes the cruelty of mother-child separation to the extreme.

In fact, this animation is not about bitterness, because its real core is not separation, but growth.

In the process of wandering, Beckham has grown from a little suckling cat who was ridiculed as "barking like a mouse" to a strong and brave "white leopard", and even learned to glide by flying squirrels.

So looking back, "abuse" is just the appearance of Beckham’s Wandering.

What we will eventually arrive, the original taste of lonely and painful growth, is what it wants to convey more.

If you think that this kind of "abuse" for children is not deep enough, there is a complicated abuse method in domestic animation.

After 2000, domestic animation entered the peak creation period, and countless masterpieces emerged. What I have to mention is that it has a peak level. Biography of Lan Tu, the Rainbow Cat..

This animation, in the present words, is "2006 explosion".

It was so popular that every primary school student dared to grab the remote control from his parents and wait for updates in front of the TV.

The fire made the students frantically collect the plastic version of the "Seven Swords", and the opening was "Changhong Penetrating the Sun" and "Fire Dance Whirlwind".

It can be said that my happiest thing in those days was to move a small bench with my sister and sit in front of the TV to watch Rainbow Seven.

As a children’s animation, Hongqi is talking about the adult’s martial arts world.

The villain, the black-hearted tiger, led the evil cult in an attempt to dominate the world. As a descendant of the seven swords, the rainbow cat went down the mountain to find other descendants of the six swords to stop the atrocities. Only the combination of seven swords can defeat the black-hearted tiger and defend the peace of the earth.

But in such a passionate martial arts story, The most abusive person turned out to be the villain Black tiger..

Black tiger is a young demon master. He adores Lan Tu with all his heart, knowing that they can’t be, but he is still infatuated.

When I was a child, I liked Rainbow Cat and Lan Tu, and I thought they should be a couple, so I hated seeing Black tiger.

Including his pursuit of Lan Tu, it seems to me that "a toad wants to eat swan meat", and he is an out-and-out bad guy.

But it was later discovered that, Black tiger is a very complicated role..

He will kill the seven swords without mercy.

Will also show childlike innocence in front of his father, full of tenderness in front of Lan Tu.

He was ambitious, capable and persistent, and eventually he died because of his crazy obsession.

Hongqi’s values are diverse. It will argue about "the opposition between good and evil" and discuss "which is right and which is wrong". As Black tiger’s voice asked:

"What is positive and what is evil? Is it wrong for me, Black tiger, to help my father wholeheartedly? "

Black tiger has the pain of not loving, but also the pride of being a villain.

His whole role is very full, from aboveboard in the early stage to "blackening" in the later stage.

That’s why, Black tiger can make small audiences still remember it after many years.

And those details that we ignored in those years are exactly what the screenwriter wants to express in the animation kernel.

Rainbow Seven shows us the most complicated and unspeakable part of human nature in the form of animation, and it doesn’t give the only answer to anything.

It provides us with more angles to interpret the world, boldly gives the power of interpretation to children, and at the same time, it also gives humanity the gentlest touch.

When taking stock of the domestic heart abuse animation, I found that there is a deeper abuse method that has been ignored by us.

It is not a bitter tear, nor is it as complicated as the emotional touch of Hongqi.

It’s not for children, Its tragic implication can only be truly understood by adults.

For example, it was broadcast in 2007. Chef Xiao Fugui.

It may be "the loudest animation in childhood", and the dubbing is a bit spicy.

But it is also "the most thoughtful animation in childhood", and everyone who grows up after 90 will break out in a cold sweat in retrospect.

The tragedy of this animation is not in the plot, but in its bold ending.

It dares to break the inherent "truth, goodness and beauty" and "happy ending" of domestic animation and give children a critical blow from reality.

This attack was not only fierce enough at that time, but after many years, when we really tasted the taste of life, the abuse point continued.

In fact, from the story background, we can guess that this animation is not simple:

It happened in the stormy late Qing Dynasty.

Xiao Fugui’s grandfather was framed and imprisoned. In order to save his grandfather, he had to get the golden kitchen utensils and become the chief royal chef of Cixi, which is also the core task of the whole play.

However, at the instigation of the villain K, the eunuch Xiao Lizi constantly made trouble for Xiao Fugui, and once caused Xiao Fugui to lose his taste.

But in the finale, Xiao Fugui finally found it difficult to get the gold kitchen utensils, but his grandfather in prison died suddenly at the moment he learned the news.

He died alive and happy.

In order to save Xiao Fugui, the old doctor died with the bad guys.

Xiao Fugui wanted to accuse Lord K of conspiracy, but there was no evidence.

The only flying butterfly who is really kind to him has already been forced out of the palace, and I don’t know where he is.

This seemingly prosperous court has no place for Xiao Fugui, and he has lost all important people.

And Xiao Lizi, the reason why he has been targeting his friend Xiao Fugui is only because Lord K threatened his parents’ lives.

But he didn’t know until the finale, His parents starved to death in the street as early as when he entered the palace as a eunuch.

He cried bitterly: "Lord K, you lied to me! I killed Xiao Fugui. My friends who really treated me well have all gone, Xiao Fugui and Xiao Feidie, where are you? "

From the leading role to the supporting role, no one has a good end.

When I watched it, I was too young. I just thought the ending was too cruel to watch, and I couldn’t understand the painstaking efforts of the producers. I don’t understand why I couldn’t give everyone a perfect ending.

Later, when I grow up, I find that reality is not utopia, and those things that make you powerless happen all the time in this world.

Just as we can’t delay our parents’ aging and death, and we can’t recover the lost love, the friends who were once close again are just friends who are praised by friends when they meet again.

The truth that these adults learned only after they experienced it was hidden in the ending of an animation.

It silently bears all the incomprehension of the audience and has been waiting for you to grow up and understand.

Some people say that the ending of "The Chef Little Fugui" is desolate and tragic like "The Water Margin". The separation of relatives and friends and the collapse of the dynasty building are the tragedies of naked individuals and times, and the tragic ending of the protagonists is the best metaphor of the dynasty’s desolation.

This tragic color is hardly reflected in more than 100 episodes of the plot, and small audiences will only find it interesting when they watch it in the early stage. It was not until the end that the sad background color of the animation was really revealed.

From great joy to great sorrow, it is only a moment. So are people, and so are times.

It turns out that more than a decade ago, we had such a profound animation, giving children a window to touch reality.

Think about it carefully, the post-90 s who were abused by domestic animation are not as fragile as when they shed tears.

When we were young, we watched pure abuse and felt pure where will you go;

A little older, with more complicated feelings, I began to understand the many aspects of human nature;

And the deeper sorrow and abuse needs us to experience it slowly when we grow up.

There are more than these domestic heart-abuse animations, such as Lotus Lantern, Legend of Nezha, Adventures of Little Carp, Go Boy, The Return of Tiger, Chinese Boy …

Together, these excellent animations have built the golden age of domestic animation.

The reason why we are crying while being abused is precisely because. The creators didn’t treat the children as fools and made up enough time with empty and boring plots.

They truly respect the children’s spiritual needs and show the real life with wonderful and moving stories.

They don’t shy away from death, talk about good and evil, and show the cruel grief of reality to their children.

Whether it’s the true feelings of mother and son, the passionate feelings of Jianghu children, or the bright and dark side of human nature, you can find the answer in these animations.

These seemingly cruel animations just give a generation of children a strong spiritual power and tell us what is good, what is evil, what is true and what is false.

Even if I grow up in tears, I still have the courage and hope to face life.

If you have been abused by these animations, just click one. "Watching"Ok.

Thank you to those pioneers who dreamed our dreams and dared to break them. Thank you for bringing us all smiles and tears.

That is the truest appearance of life..

BYD Fuel Vehicle Quotation

In the current China auto market, we can see that the market trend between independent brands and joint venture brands is changing obviously: driven by technology, the prices and sales of independent brands are rising all the way, while the prices and sales of joint venture brands are falling all the way. Especially in the mid-to high-end car market, it used to be the dominant position of joint venture brands. However, taking Buick LaCrosse as an example, its monthly sales volume has dropped to 1,000 or 2,000 at the lowest before the replacement, while new cars have to be traded at a price, and the main sales models have been fully retreated to 200,000, and the price of the 1.5T entry-level version is only 179,900 yuan. On the other hand, China brands, such as the champion BYD Han series, have an average transaction price of more than 260,000, with a cumulative sales volume of more than 480,000 vehicles, even exceeding 30,000 vehicles for four consecutive months.

On May 18, 2023, BYD, which dominated the list in an all-round way, made another effort to launch the Han DM-i Champion Edition and the Han DM-p Ares Edition, and once again launched an impact on the mainstream fuel B-class car market with the market strategy of "the same price for oil and electricity". Among them, the price range of Han DM-i Champion Edition is 189,800 yuan to 249,800 yuan, which is 28,000 yuan lower than the entry price of 2022 models. The price of Chinese DM-p Ares Edition with 3.7-second acceleration performance is 289,800 yuan.

First of all, let’s look at Han DM-i Champion Edition, which takes Xiaoyun-plug-in special turbocharged 1.5Ti high-efficiency engine, EHS electric hybrid system and DM-i super hybrid special power blade battery as the core, and brings subversive experience in power, economy and comfort. It accelerates in only 7.9 seconds, which is comparable to the 2.0T engine. According to the different battery capacity, 121km and 200km pure electric endurance versions (NEDC working condition) are provided. When driving in urban areas, the motor is used for driving in 99% working conditions, and the engine is used for auxiliary driving at high speed. Therefore, it not only has the driving feeling infinitely close to pure electric vehicles, but also has the lowest fuel consumption of 4.2L/100km and the longest comprehensive cruising range of oil and electricity of 1260km.

In terms of appearance, the Han DM-i Champion Edition adds the color of glacier blue car, and adopts two core materials technologies of BASF, which not only has a light and moist color, but also has a special metallic texture, which complements the national tide design of the Han DM-i Champion Edition. In addition, Han DM-i Champion Edition comes standard with NFC car keys, which supports Android and Apple devices, greatly improving the convenience of car use. At the same time, BSD blind spot monitoring and W-HUD head-up display are also on board, and active safety is strengthened. In addition, the Han DM-i Champion Edition comes standard with ten core high-end configurations, which are high at the beginning, which once again puts pressure on the poor joint venture B-class sedan.

As the first super hybrid coupe modified for mass production, the Han DM-p Ares Edition pays tribute to Huo Qubing, the God of War, which is a model of luxury coupe in China, both in internal and external design and performance. Basf’s third-generation black paint is used to match the black color, which is deep and shimmering. With blackened sports wheels, matte black logo, black metal triangular windows and frames, it shows the powerful visual impact of performance cars. A series of sports elements and high-grade materials have also been added to the interior of the Ares edition, such as extremely black high-grade suede covered seats, door panels, passenger side panels, central control armrest boxes, etc., supplemented by black carbon fiber materials, and equipped with integrated sports seats and golden yellow seat belts. The interior and appearance of the whole vehicle complement each other and the sense of sports is bursting.

In addition to the design highlights, the performance of Han DM-p Ares Edition is even more amazing under the blessing of DM-p King. Its peak horsepower reaches 580Ps, the maximum torque reaches 822N·m, and the fastest acceleration of 100 kilometers takes only 3.7 seconds! At the same time, the golden yellow high-performance four-piston fixed pliers can escort the ultimate performance output. In addition, in terms of energy efficiency, it can be powered by oil and electricity. Under NEDC working conditions, the battery life is 200km, the fuel consumption is only 5.2L, and the comprehensive battery life is 1120km.

别克君越

As a subversive of traditional fuel vehicles, BYD Han has mastered the market dominance in the field of more than 200,000 mid-to high-end cars. Compared with the Buick LaCrosse (with a price of 179,900 to 239,900) recently listed, the body size is very close, and the prices are highly overlapped. However, BYD Han DM has stronger power than LaCrosse, lower fuel consumption than LaCrosse, more configurations than LaCrosse, and can drive purely by electricity. No matter which dimension is compared, it is obvious which is better or worse, so the future sales performance can be imagined.

AITO asked about the cruising range of M7.

AITO asked the M7′ s cruising range to perform well.

Under the condition of high-speed working condition accounting for 2/3, the new M7 has actually run 743 kilometers, the remaining oil can run more than 70 kilometers, and the electric energy can run 50 kilometers, which adds up to about 880 kilometers, plus 20 kilometers can approach 900 kilometers.

China Automobile Research Test shows that the actual cruising range can reach 1,290 kilometers with full oil and electricity, and the instrument shows that there are still 10 kilometers left, with an average fuel consumption of 5.2L/100km, which has a good performance in complex roads such as urban areas, expressways and expressways.

The reason why the M7 can have such endurance performance lies in the technical research of Celeste. It is built on a self-developed pure electric drive intelligent platform, equipped with a 1.5T four-cylinder special range extender, and adopts deep Miller cycle technology. The peak power is as high as 92kW, the thermal efficiency is as high as 41%, the compression ratio is 15:1, and the oil-electricity conversion rate is 3.13kW h/L, which can effectively improve the endurance level.

In the low temperature environment, the afterheat of the range extender can also be used to improve the low temperature endurance and the heating of the passenger compartment.

In order to reduce energy consumption, Wenjie M7 has made many optimizations in the whole vehicle design, such as using low-resistance calipers, low-resistance hub bearings, low-rolling tires, hidden door handles, hidden wipers, etc., to achieve lower mechanical resistance of the whole vehicle.

Its battery pack adopts Contemporary Amperex Technology Co., Limited CTP battery pack, with a battery capacity of 40kWh. The charging and discharging efficiency of the whole vehicle reaches over 90%, and the pure battery life of the two-drive comfort CLTC can reach 230km, which can meet daily commuting.

In a word, the cruising range of the M7 has excellent performance under different working conditions.
