Scientists crack the truth of Covid-19’s death. Immune cells "frustrated infection" induced inflammatory storm

The COVID-19 epidemic has lasted for more than four years, and Covid-19 is still raging around the world. According to statistics, nearly 7 million people infected with COVID-19 around the world have died of infection. In fact, the main cause of illness deterioration and even death of most patients is not the virus itself, but the excessive inflammatory reaction and inflammatory factor storm caused by Covid-19. However, the specific mechanism of how the virus triggers such a strong inflammatory response in the lungs is still unclear.

Recently, the Chinese research team of the University of Southern California published an important achievement in the journal Nature Cell Biology. Studies have revealed that Covid-19 can trigger a stronger inflammatory response than other RNA viruses. Surprisingly, this inflammatory factor storm is not caused by the rapid replication infection of the virus to lung epithelial cells, but by the "frustration infection" of the virus to a large number of immune cells pouring into the lungs in the later stage, that is, the virus can not complete the replication infection process.

The researchers further revealed the mechanism of Covid-19 infecting immune cells and triggering the storm of inflammatory factors: Toll-like receptor 1(TLR1) on the surface of immune cells recognizes the structural proteins E (envelope glycoprotein) and M (matrix protein) of Covid-19, so that the virus is endocytosed, thus causing "frustration infection". In addition, the binding of Covid-19 envelope glycoprotein E to immune cells TLR1 can directly activate the inflammatory response of immune cells, leading to the release of pro-inflammatory factors, which is the root cause of cytokine storm caused by Covid-19.

Dr. Duan Tianhao, Dr. Xing Changsheng and Dr. Chu Junjun are the co-first authors of this paper, and Professor Wang Rongfu is the correspondent author.

In order to explore the uniqueness of Covid-19’s strong inflammatory response, scientists screened 27 kinds of protein coded by Covid-19. Studies have revealed that Covid-19-encoded protein named NSP14 can directly promote the phosphorylation of IKK, a key kinase complex in the inflammatory signaling pathway, and significantly enhance the inflammatory response.

Interestingly, another Covid-19-encoded protein named ORF6 can inhibit inflammatory reaction and can be anchored to cell membrane. ORF6 significantly inhibits the activation of inflammatory reaction by preventing the nuclear entry of inflammatory transcription factor NF-κ B..

However, NSP14 promotes inflammation and ORF6 inhibits inflammation. What will be the final result of these two actions? Scientists have noticed that there was no obvious inflammatory reaction in the early stage of Covid-19 infection, but the inflammatory reaction increased significantly in the middle and late stage. This suggests that NSP14 and ORF6 may have different expression patterns at different stages of infection, which may lead to clinical observation.

After consulting the data, scientists noticed that there was a large amount of immune cell infiltration in Covid-19’s lungs at the late stage of infection. This leads to a guess: Will these infiltrated immune cells be infected by Covid-19, and then release a large number of inflammatory factors?

To answer these questions, researchers conducted a series of experiments. They used a modified version of Covid-19 labeled with green fluorescence to infect lung epithelial cells and immune cells respectively. The results showed that only lung epithelial cells showed fluorescent signal, indicating that Covid-19 could only replicate when infected with epithelial cells, but could not replicate when infected with immune cells (frustration infection). On the contrary, although a low level of inflammatory reaction activation was detected in lung epithelial cells, a strong inflammatory signal activation was detected in immune cells.

Scientists speculate that the different expression patterns of NSP14 and ORF6 in lung epithelial cells and immune cells may lead to the inhibition of inflammatory reaction in epithelial cells and the activation of inflammatory reaction in immune cells, which may be related to Covid-19’s "frustrated infection" in immune cells.

Traditionally, lung epithelial cells are the main target of infection in Covid-19, because there is a key receptor protein ACE2 on its surface, which can bind to Covid-19 spike protein S and promote the virus to invade cells. Immune cells, on the other hand, are not considered to have ACE2 receptors, so they are usually not considered to be infected by Covid-19.

However, further research shows that Covid-19 can infect immune cells despite the lack of ACE2 receptor, but due to the lack of ACE2, the virus cannot replicate after entering immune cells (frustration infection). What is even more surprising is that this "frustration infection" causes Covid-19 to selectively express NSP14 protein which promotes inflammatory response, but not ORF6 protein which inhibits inflammation, thus aggravating the inflammatory response of immune cells and promoting the generation of inflammatory storm.

Accordingly, scientists describe the complete mechanism of inflammation induced by Covid-19:

In the early stage, Covid-19 mainly infected lung epithelial cells through ACE2 receptor, where the virus quickly replicated and released a large number of virus particles to infect other epithelial cells. Although lung epithelial cells also express a small amount of TLR1 receptor and can be activated by virus, the expression of TLR1 in epithelial cells is much lower than that in immune cells, and the activation level of inflammatory signals is weak. In addition, due to Covid-19’s massive expression of inflammatory inhibitory protein ORF6 in epithelial cells, the inflammatory reaction was effectively inhibited. Therefore, the early stage of Covid-19 infection is mainly characterized by virus replication, accompanied by weak inflammatory reaction, that is, asymptomatic infection period.

In the late stage, the viral load reached the peak, the replication speed decreased, and a large number of immune cells gathered in the lungs. Immune cells recognize and bind the structural proteins E and M of the virus through the highly expressed TLR1 receptor, which triggers the activation of severe inflammatory reaction. At the same time, the virus binding to TLR1 can enter the immune cells through endocytosis. This "frustrated infection" mode prevents the virus from forming a replication and transcription complex RTC to transcribe the subgenomic RNA of the virus. Due to the lack of subgenomic RNA, viral structural proteins and viral accessory proteins including ORF6 cannot be expressed, but the pro-inflammatory protein NSP14 can be directly translated through genomic RNA. Because only NSP14 is expressed without ORF6, the inflammatory reaction is further aggravated, and immune cells release a large number of inflammatory factors, triggering a storm of inflammatory factors.

In addition, scientists have also studied other human coronaviruses of Coronaviridae. They found that SARS-CoV-1 triggered a large number of inflammatory reactions through the same molecular mechanism as SARS-CoV-2, and even the ability of its E protein to induce inflammation in immune cells was higher than that of SARS-CoV-2. This explains why the mortality rate of SARS-CoV-1 was as high as 11% when it broke out 20 years ago, far exceeding the current epidemic of SARS-CoV-2.

In contrast, other mild human coronaviruses, such as OC43, NL63 and 229E, have weak binding ability to TLR1, which also explains that their symptoms are usually mild.

This study reveals in detail the complete molecular mechanism of Covid-19 from its early entry into the human body for replication to its late stage, which leads to severe inflammation and death of patients, and provides important theoretical guidance for the treatment of severe COVID-19 patients. At the same time, the study also found that the small molecule inhibitor of TLR1 may be a better choice for the treatment of severe COVID-19 infection.

Policy Interpretation of Provisions on Examination and Approval of Land for Demolition and Reconstruction Urban Renewal Projects in Shenzhen (Press Release)

  I. Policy background

  In 2016, the city implemented the decentralization of urban renewal and strong areas. According to the Decision of Shenzhen Municipal People’s Government on Implementing the Reform of Urban Renewal (Order No.288 of Shenzhen Municipal People’s Government) (hereinafter referred to as Order No.288) and the Decision of Shenzhen Municipal People’s Government on Deepening the Reform of Planning Land System and Mechanism (Order No.298 of Shenzhen Municipal People’s Government) (hereinafter referred to as Order No.298), the examination and approval authority of urban renewal projects and the implementation plan of agricultural conversion involved are adjusted to district governments (including new ones) Under the new situation of decentralization in strong areas, in order to do a good job of linking up the work among provinces, cities and districts after the reform, better guide and standardize the examination and approval of land for urban renewal projects of demolition and reconstruction, and improve the efficiency of examination and approval, the Provisions on the Examination and Approval of Land for Urban Renewal Projects of Demolition and Reconstruction in Shenzhen (hereinafter referred to as the Provisions) is formulated in combination with the relevant provisions of the state, provinces and municipalities on land management, which serves as the basis for urban renewal agencies in various districts to examine and approve the implementation plan of land for urban renewal projects and the conversion of agricultural land.

  Second, the main content

  The "Regulations" consists of nineteen articles, the main contents of which are as follows:

  (A) on the scope of application of the policy

  The "Regulations" apply to the examination and approval of the implementation plan for the development and construction land and its agricultural land conversion.

  (B) on the division of land use approval authority

  According to Decree No.288 and its implementation opinions and Decree No.298, the municipal competent department of planning and land is the competent department of urban renewal business, responsible for the policy formulation and business guidance of the implementation plan for the development and construction of land and its agricultural land conversion, and summarizes the examination and approval of each district every six months and reports it to the municipal government; The district government is responsible for the examination and approval of the implementation plan for the development and construction of land and its agricultural land conversion; The urban renewal agencies in each district are responsible for the specific examination and approval work, and the relevant departments do a good job of cooperation within the scope of their duties.

  (3) About the scope of land use approval

  Urban renewal projects are based on the scope of project demolition defined by urban renewal unit planning, and land use approval is carried out according to the phased implementation timing determined by urban renewal unit planning. The "Regulations" distinguish four situations, which involve staging but not project implementation, not involving staging but sub-project implementation, sub-project implementation by stages, and sub-project implementation by stages, and clarify the units that approve the development and construction land. If a whole area contains a number of development and construction land, all development and construction land shall go through the formalities of land use examination and approval at the same time, and the subsequent procedures shall go through the formalities of signing the land use right transfer contract at the same time.

  (four) on the land application materials and approval conditions.

  In accordance with the Decision of the Ministry of Land and Resources on Amending the Administrative Measures for the Examination and Approval of Construction Land, the Notice of the Guangdong Provincial Department of Land and Resources on Implementing the Opinions of the State on Improving and Optimizing the Pre-examination and Review of Construction Projects, and the Notice of the Shenzhen Municipal Planning and Land Resources Committee of the Shenzhen Municipal Finance Committee on Further Defining the Payment Process of Paid Use Fees for New Construction Land, The Reply on Approving to Authorize the Shenzhen Municipal People’s Government to Exercise Relevant Land Management Authority, the Measures for Urban Renewal in Shenzhen and its detailed rules for implementation, and in combination with the provisions of relevant policies such as prevention and management of geological disasters, investigation and evaluation of soil environment, the Provisions clarify the application materials and conditions for examination and approval of development and construction land and its implementation plan for agricultural conversion.

  (five) on the development and construction of land involved in the approved land without construction.

  Linked to the Detailed Rules for the Implementation of the Measures for Urban Renewal in Shenzhen and the Technical Regulations for the Planning and Compilation of Urban Renewal Units for Demolition and Reconstruction in Shenzhen (hereinafter referred to as the Technical Regulations for the Planning and Compilation of Renewal Units), the Regulations stipulate the work of this situation in the stages of urban renewal unit planning approval, project implementation subject confirmation, cancellation of real property right certificate, land use approval and land transfer from the perspective of land use approval. Following the principle of equal area, equal period, equal development intensity and other functions, the area, use, plot ratio, transfer period and start date of the vacated land shall be implemented according to the agreement in the transfer contract of the land use right of the vacated land.

  (six) the situation that the urban renewal unit contains overhead corridors, cross-street buildings or underground spaces.

  The "Regulations" are linked with the "Technical Regulations on Updating Unit Planning", and the applicants, departments and procedures for land approval for public overhead corridors and public passages outside the scope of development and construction land are defined. At the same time, the "Regulations" clarify that the horizontal projection range, area and vertical elevation of overhead corridors, cross-street buildings or underground spaces should be clear when the construction land is approved. However, considering that it is difficult to define the specific spatial location in the stage of land use approval, the Regulations propose that in the stage of construction project planning permission, the horizontal projection range, area and vertical elevation can be appropriately adjusted according to the urban renewal unit planning and relevant standards and specifications, and a supplementary agreement on the land use right transfer contract can be signed, so it is not necessary to re-apply for construction land approval.

  (seven) on the phased implementation of urban renewal units, there is a lack of legal land use indicators within the scope of later project demolition.

  Urban renewal unit planning takes urban renewal unit as a unit for overall planning, and there may be insufficient legal land use indicators within the scope of later project demolition in urban renewal units implemented by stages. In this case, if the legal land use index of the later project is insufficient, the legal land use index of the signed land use right transfer contract can be used to exceed the area of the transferred development and construction land. When there are many kinds of land use categories beyond the legal land use index, they shall be used in the order of land price calculation.

  (eight) on the urban renewal project involving non-agricultural construction land and illegal construction land left over from the history of rural urbanization.

  In accordance with the principle of respecting history and safeguarding the rights and interests of the original rural collective, and according to the order of demarcation of non-agricultural construction land, the Regulations respectively stipulate different treatment principles for non-agricultural construction land before and after the disposal of illegal construction land left over from rural urbanization history.

  (nine) on the situation that the urban renewal project involves the overlapping of non-agricultural construction land and old house village land.

  For non-agricultural construction land and the old house village land overlap, the overlapping part is treated as non-agricultural construction land, and the old house village land is not included in the legal land use index; The overlapping part is treated as the land used in the old house village, and the non-agricultural construction land can be separately included in the legal land use index within the scope of demolition, and there is no need to adjust the non-agricultural construction land plan.

  (ten) on the time limit and procedures for land use approval.

  Combined with the relevant provisions of the administrative license, the time limit for examination and approval of development and construction land is 20 working days. The approval procedure is as follows:

  Figure 1 Flow chart for approval of development and construction land

  (twelve) land transfer and non-agricultural construction land index verification.

  Urban renewal unit planning determines that the land to be handed over to the government free of charge should be handed over before the signing of the land use right transfer contract for urban renewal projects. Urban renewal projects involving non-agricultural construction land within the scope of demolition, the district urban renewal agencies shall notify the municipal competent department of planning and land to send agencies within the jurisdiction to write off non-agricultural construction land indicators before the signing of the land use right transfer contract for urban renewal projects.

  (thirteen) the time limit and procedures for the approval of the implementation plan for the conversion of agricultural land.

  If the development and construction land of the project involves the occupation of agricultural land and unused land, the implementation plan for the conversion of agricultural land shall be formulated by the district urban renewal agency and submitted to the district government for approval simultaneously with the development and construction land. The procedure is as follows:

  Fig. 2 Flow chart for approval of implementation scheme of agricultural conversion

  (fourteen) on the use of land use planning indicators.

  Before compiling the implementation plan of agricultural land conversion for renewal projects, the district urban renewal institution shall solicit the opinions of the agencies dispatched by the competent department of city planning and land administration, and clarify the sources of new construction land indicators. The dispatched offices of the municipal competent department of planning and land shall, according to the reply issued by the district government, do a good job in the ledger management of the indicators of agricultural conversion in the jurisdiction, and report to the municipal competent department of planning and land regularly for summary as required.

  (15) Information disclosure

  After the district government issues the approval of construction land and the approval of the implementation plan of agricultural conversion, the district urban renewal institution shall make the approval of land use and the implementation plan of agricultural conversion public at the project site and portal website respectively.

  (XVI) About the effective date.

  The Regulations shall come into force as of the date of promulgation.

Liu Qingquan: Let the development of Chinese medicine enter a new era.

[Editor’s Note] "We should develop traditional Chinese medicine, pay attention to interpreting the principles of traditional Chinese medicine with modern science, and take the road of combining traditional Chinese and western medicine." On May 12th, General Secretary of the Supreme Leader once again asked about Chinese medicine during his inspection tour in Nanyang City, Henan Province, and put forward new and clear requirements for the further development of Chinese medicine.

Inheriting the essence, the development of traditional Chinese medicine can go back to ancient times; The development of traditional Chinese medicine will be clear and turbulent only when it is upright and innovative. Combined with the outstanding performance and experience of Chinese medicine in the treatment of COVID-19 epidemic, many Chinese medicine experts who have participated in the first-line anti-epidemic talk about their experiences, offering suggestions and suggestions for the high-quality development of Chinese medicine and protecting the health of all mankind.

"The future development of Chinese medicine is to be brave and dare to combine with modern science and technology, and to be good at using modern science and technology language to make the oldest theory of Chinese medicine clear and clear, so that Chinese medicine can truly become a world medicine and a medical system that can be used by all countries and ethnic groups." Combined with the treatment of COVID-19 epidemic, Liu Qingquan, president of Beijing Hospital of Traditional Chinese Medicine affiliated to Capital Medical University, said that the integration of traditional Chinese medicine and western medicine is very important for the development of traditional Chinese medicine, and it may form a new medicine in the future. It not only has the traditional theoretical advantages of Chinese medicine classics, but also embodies the connotation of modern science and technology; It is neither classical Chinese medicine nor modern western medicine, but a complete medical system with complementary advantages.

The experience of Chinese and western collaborative treatment lays the foundation for the formation of new medicine.

In the process of fighting against the epidemic in COVID-19, the effective prescription of traditional Chinese medicine-"three drugs and three parties" screened out by clinic has played an important role.

Liu Qingquan, who once served as an expert in Hubei Central Steering Group and deputy head of the national expert group on medical treatment of traditional Chinese medicine, said that "three drugs and three parties" is actually a classic theory of China traditional Chinese medicine, a treatment method based on the experience of traditional Chinese medicine in treating plague for thousands of years, and a model for coping with new diseases.

"Through the analysis of COVID-19’s clinical characteristics, we have formed the idea that we can combine various effective prescriptions to treat, thus forming the basic idea of’ three parties and three drugs’, that is, according to the changes of etiology and different stages of illness, we can adjust and combine to form effective treatment methods. This proves the greatness and correctness of the theory of traditional Chinese medicine and verifies that it conforms to scientific laws. " Liu Qingquan said.

"In the process of using’ three parties and three drugs’ treatment, we have also preliminarily explored and mastered some theoretical data of treating COVID-19 with traditional Chinese medicine. These studies prove that the basis of treating COVID-19 with traditional Chinese medicine is scientifically explained from different aspects, such as the adjustment of immune system and inflammatory system, which are the important pathological links that cause the disease to change, get worse and worse during the onset of COVID-19." Liu Qingquan analysis.

"In terms of coordinated treatment of Chinese and Western medicine, Chinese and Western medicine have their own strengths, and ultimately played a very important role in improving the success rate of severe and critical care and reducing the mortality rate, which proved the internal theoretical basis of coordinated treatment of Chinese and Western medicine and made some necessary preparations for exploring the organic integration of Chinese and Western medicine to form a new medicine." Liu Qingquan pointed out.

Exploration of Traditional Chinese Medicine Shelter Hospital Model of Infectious Diseases Hospital with Integrated Traditional Chinese and Western Medicine

In the process of Chinese medicine participating in Wuhan epidemic prevention and control and clinical treatment, Fangcang Hospital has become a medical pioneering work in a special period.

Liu Qingquan, a former president of Jiangxia Fangcang Hospital, was deeply touched by the experience of Chinese medicine taking over Fangcang Hospital. He said that the establishment of the shelter hospital is a very effective way to deal with sudden large-scale infectious diseases. In the shelter hospital, the treatment of light and ordinary patients with traditional Chinese medicine can effectively speed up the improvement of patients’ condition, reduce the occurrence of severe and critical diseases and reduce the mortality rate. In addition, because the source of infection is cut off in time, the control of virus transmission also plays a very important role.

Liu Qingquan believes that the experience and achievements gained by taking over Fangcang Hospital with traditional Chinese medicine technology to treat light and ordinary patients in COVID-19 have paved the way for the state to support the establishment of infectious disease hospitals and specialized hospitals with integrated traditional Chinese and western medicine. This will enable the future to quickly form a powerful force of combining traditional Chinese and western medicine, whether dealing with common infectious diseases or sudden new infectious diseases.

Increase investment to support the construction of Chinese medicine institutions and Chinese medicine research.

Nowadays, in the treatment of many local epidemics distributed in China, the treatment scheme of traditional Chinese medicine is becoming more and more perfect and mature, and has achieved very good results. The methods of classified treatment and management of traditional Chinese medicine have become more and more popular and have become the consensus of the medical community.

"Compared with this treatment effect, there are too few medical institutions of Chinese medicine, which is a limitation to the role of Chinese medicine and its future development." Liu Qingquan called on the state to increase investment in TCM research and institution building. In dealing with infectious diseases, it is hoped that the state can support the establishment of infectious disease hospitals in mature areas with traditional Chinese medicine or integrated traditional Chinese and western medicine.

Liu Qingquan said that infectious diseases are the public enemy of mankind, regardless of Chinese medicine and western medicine, regardless of population and race. Therefore, I hope that China can make achievements in the construction of infectious disease hospitals with traditional Chinese medicine and integrated traditional Chinese and western medicine, and set an example for promoting the development of China medicine and even the world medicine. I hope that colleagues of Chinese and Western medicine can work together in Qi Xin to seize the opportunity and let the development of traditional Chinese medicine enter a new era.

Kenny Lin officially declared Taobao as the ambassador of the national brand! How does Taobao Tmall skillfully use policies to turn this wave of operation into a traffic explosion point?

  On May 13th, on the first day of Tmall’s pre-emptive purchase of 618 countries, Taobao took the lead in playing the marketing strategy of "Wang Fried"-Kenny Lin, a national artist of "900 million girls’ dream", was officially declared as the brand ambassador of Taobao countries, and magical advertisements were placed in CCTV, online mainstream APP and offline over 50 cities, brainwashing consumers across the country: "Pay close attention to Taobao and receive state subsidies!" The big promotion policy of "national subsidy+Tmall 618 subsidy as low as 50% off" has strongly reached hundreds of millions of consumers.

  In this year’s 618 event, Taobao also launched the "National Supplement Surprise Coupon" for the first time: users can grab the "National Supplement Surprise Coupon" which was launched for the first time and has the largest overlapping subsidy, and also participate in the interesting interaction of Kenny Lin, the brand ambassador of Taobao National Supplement; At the same time, watch the live broadcast of Kenny Lin on May 19th, and you will have a better chance to win the opportunity of "up to 10,000 yuan for national exemption". This "618" marketing campaign, which is based on policies, with stars as the guide, welfare as the spear and brand as the shield, once again breaks the routine and "updates" new marketing ideas, and also makes Taobao the first entrance for consumers to receive state subsidies.

  "Hurry up and update" TVC’s magical brushing screen, releasing the whole world and detonating the country’s mind.

  Consumers are blown in mid-air by strong winds, grabbing mobile phones passing by; The person at the forefront of the team reached out and grabbed Kenny Lin’s skirts, and shouted with joy, "Hurry up and update!"

  The magic advertisement in just 15 seconds directly visualizes the core idea of Taobao’s national compensation marketing: "People are blown by strong winds" vividly interprets "the wind of Taobao’s national compensation is too strong"; All kinds of home appliances that have been blown away intuitively show the rich categories of Taobao’s national supplement; The action of "Hurry up to update" is a pun, which skillfully connects the homonym of the name of Kenny Lin, the ambassador of Taobao’s national subsidy brand, with "Hurry up to receive the national subsidy from Taobao", and makes a heavy discount of "make up for it, as low as 50% off", which quickly attracts users’ attention and grabs users’ minds.

  In addition, Taobao also released several other magical TVCs, such as "Catch Kenny Lin in mid-air", "Kenny Lin City Gate Catch New Household Appliances" and "Delivery Master Catch Kenny Lin". Together with Dafeng Creative TVC, it interestingly explained the four core points of this national supplement: supplement and supplement, rich categories, new products and service mentality, which directly highlighted the interesting marketing style of this 618 Taobao.

  As the ambassador of Taobao’s national subsidy brand, Kenny Lin’s label setting has always been highly consistent with Taobao’s "affordable and interesting" platform image, and its name of "update" has formed a natural memory point with "grasping Taobao’s national subsidy". In addition, the audience flow brought by last year’s hot works such as "The Story of a Rose" and "With the Phoenix" has contributed to the spread of "grasping the update".

  In order to detonate the communication potential, Taobao released a global bombing combination boxing: CCTV launched to strengthen the credibility of the policy, covering all ages and nationwide markets; Online mainstream apps open screens and information flow advertisements accurately attack young users; The offline 50+ city business circle will be launched to create an immersive "updated" advertising experience.

  Long-term marketing drives brand value to upgrade, grasps policy dividend and highlights brand responsibility.

  When the demonic brainwashing "hurry to update" TVC swept the business circle of 50 cities across the country, Taobao’s national compensation marketing offensive became stronger and stronger-on May 19th, Taobao’s national compensation brand ambassador Kenny Lin will conduct a live broadcast. At that time, Kenny Lin will carry out a series of interesting interactions around the national subsidy, and will also give users a bonus of 10,000 yuan, star signatures, 50 rounds of red packets of rain and other super benefits, so as to create a saturated communication of "offline detonation+online fission" and continue to create a 618 marketing fever.

  Behind the lively entertainment marketing is Taobao’s deep response to the national subsidy policy: whether it is a big promotion discount, extra subsidies for trade-in, more brands and categories, more urban coverage, or the service of subsidizing 10,000 new products, large and small household appliances and home improvement, users can feel the peace of mind of Taobao’s in-depth implementation of the national subsidy policy as long as they log on to Taobao. This kind of play that turns policy potential energy into brand long-term value also adds weight to Taobao’s "good heart" as a user.

  It is worth noting that this time, Taobao, the national supplement, assembled 100 head brands for the first time to jointly make profits. Under the call of the platform, many brands actively responded to the national subsidy activities, and strongly conveyed the mind of "leading the country to make up for Taobao" by directly benefiting consumers. The collective call of many merchants not only enriched the lineup of activities, but also helped improve Taobao’s national compensation strategy. Especially under the premise that the national subsidy policy has restrictions on each citizen’s eligibility and quota, Taobao, which has gathered the most comprehensive categories, the best subsidies and exclusive service rights, has naturally become the "first entrance" for consumers to choose to receive national subsidies.

  Just like this magical TVC advertisement, Taobao’s combination of "national dividend+traffic leverage+global communication" has once again "updated" the new example of e-commerce platform 618 marketing.

It’s a common practice for college students to keep in good health. People who work too hard can’t run far.

  Recently, according to the China Youth Daily, "Ginger Soaks Foot" and "Drinking Tea for Beauty" … … With the increasing pressure of life, not only the post-90s generation who entered the workplace, but also many college students have begun to try various methods of health preservation. Health preservation is no longer the exclusive word of the elderly or middle-aged people, and the young campus groups represented by college students are constantly adjusting their lifestyles and advocating a healthier life and rest. Why are this wave of college students "trapped in health care" and "selling the old"? Many college students said that this is a way of "self-mockery" to fight anxiety and pressure.

  In many people’s cognition, college students are relaxed and chic, and can have fun relatively freely. But in fact, many college students are very bitter and tired now. It is not unusual to do homework, research and activities in class until early morning or even later.

  Under such a realistic background, it is not difficult to understand that many college students are "trapped in health preservation". Recently, a "2018 Life Consumption Trend Report" shows that based on the search volume of "Lycium barbarum" on the e-commerce platform of all ages, the proportion of search volume after 1995 increased significantly in September 2017. Honey, Lycium barbarum, whey protein, health tea and enzymes are the health foods that are keen on after 1995.

  When I was in college, I was also a "busy maniac". I was really working hard. My meals and sleep were irregular, and I also had a tendency to overeat. At that time, I thought I was still young, so I indulged myself too much and was indifferent to some early warning signals of my body. But now, nearly a year after graduation, all kinds of physical and mental discomforts have emerged, and I realize that "karma" has come and I want to "pay my debts". Therefore, now I will also force myself to keep fit, such as drinking more hot water, going to massage, eating more healthy food and running to and from work.

  The meaning of life is not temporary, but long-term. To quote a very fashionable online buzzword recently, "People who work too hard can’t run far". Who doesn’t want to "run away" on the road of life? So, please do it and cherish it.

  Of course, it is not enough to rely solely on the self-awakening of young people, but also to exert efforts at the social level. To put it bluntly, in addition to focusing on the "burden reduction" of primary and secondary school students, the social level should also focus on the "burden reduction" of young people represented by college students. There is no denying that the latter should be under pressure and responsible, and strive hard to realize their own value and social value, but all this should not be at the expense of health. It should be a social consensus that only a good body and a healthy lifestyle can create more shocking values.

Increased ultraviolet radiation during the Permian extinction? Evidence of "sunscreen" in fossil pollen grains

The extinction at the end of Permian 252 million years ago caused the extinction of about 81% marine species and 89% terrestrial species. The main reason is believed to be the environmental change caused by large-scale volcanic eruption, but there is still no direct evidence that environmental factors affect terrestrial ecosystems. In cooperation with foreign counterparts, researchers in China discovered the direct evidence that the destruction of the ozone layer led to the extinction of terrestrial life at the end of Permian by studying the changes of "sunscreen" content in fossil pollen grains during this period.

The research results were published online in the internationally renowned journal Science Advances on January 6, 2023.

Volcanic eruption led to mass extinction of land? There was a lack of direct evidence

The extinction event at the end of Permian was the largest extinction event in Phanerozoic. Scientists generally believe that the increase of global greenhouse gases caused by the eruption of Siberian igneous province at the end of Permian, global warming and ocean acidification may be the main causes of this extinction. However, there are still many debates about how these environmental factors affect terrestrial ecosystems.

Some palynologists have found some deformed spores and pollen in the continental Permian-Triassic transition section. It is speculated that these deformed spores or pollen may be caused by the increase of ultraviolet radiation induced by the destruction of the global ozone layer caused by halogen elements ejected from the Siberian igneous province. However, the study of abnormal spores and pollen produced in modern plants shows that the environmental background of these abnormal pollen and spores is very complicated, and drought, air pollution and plant trauma may all induce abnormal spores or pollen to be produced in plants. Therefore, the discovery of a small number of abnormal spores and pollen in the continental Permian-Triassic transition section cannot directly prove that there was an increase in ultraviolet radiation caused by the global ozone hole during the extinction at the end of Permian.

Using the content of "sunscreen" to deduce the intensity of atmospheric ultraviolet radiation

Plants need sunlight for photosynthesis to provide energy for plant growth, but at the same time, it is necessary to avoid the damage of harmful ultraviolet rays in sunlight to genetic information in plants, especially in plant reproductive cells (spores and pollen). In order to adapt to the terrestrial radiation environment, terrestrial plants have evolved some regulatory mechanisms to reduce the damage of ultraviolet rays to plants. In the germ cells of plants, this mechanism is manifested in that there are a large number of compounds-coumaric acid and ferulic acid-in the outer walls of plant spores and pollen, which are very similar in function to "sunscreen cream". These compounds can form resonance-stable phenol free radicals and resist the oxidation caused by ultraviolet rays, thus protecting fragile spores and pollen and providing guarantee for the spread and reproduction of terrestrial plants.

Modern botanists have observed that plants can automatically adjust the content of "sunscreen" on the outer wall of their germ cells according to the surrounding ultraviolet radiation environment, and these "sunscreen" can be stored in the outer wall of inert spores and pollen for a long time. Therefore, in theory, researchers can determine the content of "sunscreen" in these spores and pollen, and deduce the intensity of atmospheric ultraviolet radiation in geological history.

"Sunscreen" is difficult to digest and has low nutrition, or leads to the extinction of insects.

According to Liu Feng, a researcher at Nanjing Institute of Geology and Paleontology, Chinese Academy of Sciences, the research team quantitatively measured coumaric acid and ferulic acid in 1011 pollen grains from Permian-Triassic transition section in southern Tibet, China. Through the big data analysis of infrared spectra produced by these pollen, the research team found that during the extinction at the end of Permian, the contents of coumaric acid and ferulic acid in the outer wall of pollen in the stratum were significantly higher than those in fossil pollen before and after extinction, which directly proved that there was an increase in global ultraviolet radiation during the extinction at the end of Permian.

The increase of ultraviolet radiation in the air has a far-reaching impact on the whole terrestrial ecosystem. Because ultraviolet rays not only have a strong killing effect on plant germ cells, but also cause damage to plant mesophyll cells. In order to resist the damage of ultraviolet rays to mesophyll cells, plants will synthesize lutein, coumaric acid and ferulic acid in their leaves, which will reduce the synthesis of chlorophyll accordingly, leading to the weakening of photosynthesis of plants, which will further weaken the absorption capacity of plants for greenhouse gases, further aggravating the global greenhouse gas increase caused by volcanic eruption at the end of Permian.

In addition, lutein, coumaric acid and ferulic acid in mesophyll are compounds that are difficult to digest and have low nutritional value for herbivores and insects, so the increase of ultraviolet radiation indirectly affects the terrestrial food chain, which may be the main reason for the extinction of terrestrial herbivores and insects at the end of Permian.

Haier commander refrigerator and Haier refrigerator difference Haier commander refrigerator and Haier refrigerator introduction [detailed explanation]

  The brand awareness of Haier refrigerator is very high. Many people have heard that Haier Commander Refrigerator and Haier Refrigerator are the same. What is the difference between Haier Commander Refrigerator and Haier Refrigerator? Why is the price gap so big? The following small series will give you a specific analysis. Let’s take a look.

  Haier tongshuai refrigerator

  Commander-in-Chief is the third sub-brand of Haier Group after Haier and casarte, and it is a customized home appliance brand launched by Haier Group under the background of the Internet era. In 1998, the commander-in-chief brand was exported to the European market as an overseas marketing platform.

  Haier Group products have three brands, Haier, casarte and Commander-in-Chief. Haier refrigerator and Haier Commander refrigerator are both brands of Haier refrigerators, but they are put into different markets. Commander series belongs to Haier’s low-end and mid-end brands. In the early stage, home appliances went to the countryside as Commander refrigerators, and casarte series was the high-end brand of refrigerators.

  The product appearance of Haier refrigerator and Haier commander refrigerator may be different. Haier staff said that Haier’s commander-in-chief brand and Haier brand refrigerator are the same in terms of development and production technology, but the brands are different and the materials of some refrigerators are different. The product quality is the same, and the commander-in-chief also provides product customization.

  Generally, Haier refrigerators have refrigerator specification labels (or refrigerator nameplates) attached to the inner wall of the refrigerating room or the back of the refrigerator, which indicate the specifications, models (such as "BCD-216YH silver gray" for a 216-liter silver gray refrigerator), power, circuit diagram and so on. Haier’s products exclusively used in urban and rural areas are generally not fully labeled or not labeled at all, but the performance of the products is the same as other products. For the refrigerators exclusively used, only the refrigerators are more suitable for the supply and demand sides.

  The difference between Haier commander refrigerator and Haier refrigerator is here for everyone. You should be able to distinguish between the two refrigerators now, and also introduce the relationship between them. In the future, you can clearly distinguish when buying Haier refrigerator. I hope the content introduced above can help those in need.

  Recently, a single mother suffering from cancer in Changgou Village, Dashuiquan Town, Xinglong County, Chengde City, Hebei Province left a message on People’s Daily Online "Local Leaders Message Board" asking for help, hoping that the government could help her find a rescue agency to raise and take care of her adopted daughter with intellectual disability.

  The Social Situation and Public Opinion Office of Chengde Municipal Committee has replied at the bottom of the message board that the relevant units of Chengde Civil Affairs Bureau and Xinglong County have carefully checked. After active coordination, relevant issues have been properly solved.

  On July 5, a staff member of the Civil Affairs Bureau of Xinglong County, Chengde City told The Paper that at present, the child has been sent to Chengde Welfare Institute, which is responsible for his daily life; The mother of the child still needs regular medical treatment. At present, in view of the above situation, relevant problems have been arranged to be solved.

  On July 5th, a staff member of Xinglong County Party Committee Office told The Paper that the mother was divorced, suffering from advanced cervical cancer, and her adopted child was mentally disabled. A month ago, they raised about 6,000 yuan for it and have completed the last phase of chemotherapy. At present, the mother is in good health and will be reviewed in three months. "The follow-up cost is not very high. She is now working with her friends and earning a little money. There is nothing wrong with life at present. " The staff member said that in the next step, after her body recovered, the mother was going to set up a stall in the market.

  The above-mentioned staff said that they would continue to follow up her physical condition and provide corresponding help.

  The staff member also mentioned that at first, the mother had no time to rest because she needed to take care of her children alone for 24 hours. She thought she had no hope of recovery, so she gave up treatment and went through the procedure of donating her body. At present, the child has been arranged to be taken care of by Chengde Welfare Institute. He said that local volunteers will also be regularly organized to go to the welfare home with the mother to see the children.

  On the same day, a staff member in charge of subsistence allowances in Xinglong County said that they had raised the low premiums of mother and daughter to the highest standard. Originally, the mother’s monthly fee was 245 yuan, and the daughter’s monthly fee was 255 yuan. Now, both of them have been raised to 400 yuan per person per month.

  The Paper noticed that the aforementioned single mother wrote on the message board that in 2006, she lost her fertility due to tubal blockage and ectopic pregnancy surgery; In 2013, her mother adopted a baby girl from a pair of Tianjin parents under the age of 18. Subsequently, the baby girl was raised by her, but unfortunately she suffered from encephalitis, which caused secondary mental disability. To this end, she borrowed 300,000 yuan to treat her children.

  She also wrote that she divorced her husband in 2019. Because the opposite sex was not related by blood, her ex-husband could not be the guardian of her adopted daughter alone, and the court awarded her custody of the child. The child is 9 years old this year. He can’t take care of himself and needs long-term care. In July 2020, she was diagnosed with advanced cervical cancer. After radiotherapy and chemotherapy, she is still receiving follow-up treatment. However, because she found it too late to surgically remove the lesion, she was extremely weak and thus lost her ability to work.

  "Give the child a chance to live when I have to say goodbye to this world." The single mother wrote.
