The State Council Information Office today (June 7) published the white paper "China Action Against New Coronary Pneumonia" and held a press conference.

　　Regarding the research and development of the new crown vaccine, Minister of Science and Technology Wang Zhigang responded that from the history of human response to the epidemic to the human understanding of the virus today, the vaccine is still the fundamental strategy for defeating the new crown virus. However, vaccine development is a very complex and rigorous scientific activity, which is difficult and long-term. Because it is scientific research, it has great uncertainty.

　　Wang Zhigang said that the safety, effectiveness, and accessibility of vaccine research and development should be placed in an important position, and international cooperation should be strengthened during vaccine development and in the future. If the Chinese vaccine is successfully applied, it will implement its commitment and provide it to humans as a global public product.

The government work report said that no specific target for the annual economic growth rate was proposed, mainly because the global epidemic situation and the economic and trade situation are highly uncertain, and China's development is facing some unpredictable factors. In doing so, it is helpful to guide all parties to concentrate on "six stability" and "six guarantees". "Six Guarantees" is the focus of this year's "Six Stability" work. Keeping the bottom line of the "six guarantees" can stabilize the economic fundamentals; to promote stability and make progress through stability, we can lay a solid foundation for building a well-off society in an all-round way.

This year's deficit rate is planned to be set at more than 3.6%. The fiscal deficit scale will increase by 1 trillion yuan compared with last year. At the same time, 1 trillion yuan of special anti-epidemic bonds will be issued.

The Chinese scientific research team recently published a paper online in the United States "Science" magazine that they found two human monoclonal antibodies that can effectively block the infection of the new coronavirus, which is expected to be used in the development of anti-new crown drugs and vaccines.

Many units including the Capital Medical University of China, the Institute of Microbiology of the Chinese Academy of Sciences, the Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences, and the Third People's Hospital of Shenzhen participated in this study.

The researchers isolated four human monoclonal antibodies from the peripheral blood mononuclear cells of a newly rehabilitated patient.

Experiments show that these four antibodies have the ability to neutralize the new coronavirus. Among them, two antibodies called B38 and H4, respectively, can block the binding of the receptor binding domain of the new crown virus spike protein and its receptor "Angiotensin Converting Enzyme 2 (ACE2)".

A number of previous studies that revealed the infection mechanism of the new coronavirus have shown that the virus mainly achieves infection through the binding of its spike protein receptor binding domain to ACE2 on human cells.

Experiments have shown that B38 and H4 respectively recognize different epitopes of the receptor binding domain. Mouse experiments confirmed that these two antibodies can reduce the amount of virus infecting the lungs of mice, showing a therapeutic effect. The two antibodies can also be used in combination to more effectively suppress viral infections.

The research team further analyzed the structure of the complex formed by the new crown virus spike protein receptor binding region and B38, thus revealing the molecular mechanism of B38 blocking viral infection.

Researcher Introduction

The latest research shows that the two antibodies screened have the potential to be further developed into new coronavirus infection drugs, and provide a basis for vaccine design. At present, the two antibodies have been transformed into products by related companies, and are expected to be used for clinical treatment of patients with new crowns in the future.

May 15th News The US Department of Commerce announced that it will extend Huawei's temporary license for another 90 days and postpone until August 13, 2020.

Since May 2019, the U.S. Department of Commerce has included Huawei on the list of entities for national security reasons. However, the department has subsequently extended the temporary licensing restrictions several times. Prior to this, the US Department of Commerce had extended it to May 15, 2020.

It has previously been reported that the US Department of Commerce ’s Bureau of Industry and Security has extended Huawei ’s temporary General Permit four times, which authorizes certain limited transactions in transactions involving export, re-export and transfer. According to the provisions of the "Export Management Regulations", Huawei and its non-U.S. Branches are provided with items subject to the entity list.

On May 14, a reporter from CCTV interviewed Ran Chengqi, director of China Satellite Navigation System Management Office. Ran Chengqi said that China plans to launch the last Beidou satellite next month, which is also the "end star" of China's Beidou-3 system. The last satellite of the Beidou-3 system to be launched is a geostationary satellite. Prior to this, China's Beidou system has provided services to the world.

Ran Chengqi, Director of the China Satellite Navigation System Management Office: Our Beidou (No. 3 system) has a total of 30 satellites, and now has 29 satellites, and the last satellite. At present, both the satellite and the rocket have entered the launch site, and we are preparing for the pre-launch work, which is expected to be implemented as planned.

Beidou No.3 system is the third step of the construction of Beidou satellite navigation system in China. After completion, it will provide services to the whole world. After the successful launch of the satellite to be launched next month, it will be officially put into operation after a period of on-orbit operation.

Ran Chengqi, Director of the China Satellite Navigation System Management Office: After the launch of this satellite, at an appropriate time this year, we will announce the completion of the global system and provide all of our Beidou services, including basic services such as this, as well as high precision Service, Beidou short message service, etc., we will have a comprehensive service opening, will also bring new highlights to the world satellite navigation.
