The night in Wuhan is quiet.
On March 9, in the mobile testing laboratory of the Central Theater Command General Hospital, Jiang Tao, a researcher at the Military Medicine Research Institute of the Academy of Military Sciences, reviewed the last sample test data and solemnly signed his name on the test report.
At this time, Komiks 1960 witch cloth draw was already 5 a.m.
He is an expert in virology and a warrior who aided Africa and fought against Egypt. This outbreak of the new crown pneumonia epidemic, he was once again ordered to go to the front line after a long battle.
Human life is at stake and accurate inspection is required
Nucleic acid testing is crucial for early clinical detection, early diagnosis, early isolation and early treatment, and is a key technical support for effective prevention and control of the new crown pneumonia epidemic.
”Behind the cold sample tube is the patient’s fresh life and health. If a diagnosis is released early, the inspection will be carried out earlier.” Jiang Tao said Cinema 1950 witch cloth draw. On January 26, a military medical expert group led by Chen, led by the Chinese Engineering Academy and a researcher at the Military Medicine Research Institute of the Academy of Military Sciences, arrived in Wuhan, Hubei, quickly established a joint defense, joint control, joint treatment and joint research work mechanism with relevant military and local units on the pathogen transmission mutation, rapid detection technology, vaccine antibody development, etc. of the new coronavirus.
According to the division of tasks, Jiang Tao led the testing team to build a nucleic acid testing platform in the experimental cabin overnight.
Focusing on three aspects: ensuring biosecurityKomiks 1960 witch cloth draw, improving detection efficiency and detection accuracy, Jiang Tao took the lead in formulating biosafety operation specifications and emergency plans, reasonably testing division of labor according to the characteristics of the team members, and using a self-developed testing kit to adopt a fully automatic high-throughput extractor, laying the foundation for achieving rapid and efficient testing.
Receive samples, sorting numbers, nucleic acid extraction, reagent preparation, and machine amplification, the results are interpreted, and the nucleic acid testing machinery is boring and full of risks.
The biggest risk is the invisible virus. If the nucleic acid extraction step is not completely cleaved or inactivated thoroughly enough, it is possible to expose the tester to danger.
Jiang TaoKomiks 1960 witch cloth draw always takes the longest time and risky nucleic acid extraction. After the sample Babaylan 1990 cloth draw is extracted, he will arrange some personnel to rest and stay in the laboratory and wait for the final result.
A full-process nucleic acid test is relatively fixed from the number of tests in a single batch to the preparation for entering and exiting the cabin and the testing time. Sometimes the number of samples sent for inspection is large. The test personnel not only take turns to work, but also have to work overnight. Finally, they confirm that the results are until four or five in the morning. Li Hao, a researcher at the testing team, said that this situation will be encountered once every few days.
”Everyone should open their eyes wide. Be sure to take good protection when receiving and processing samples, and be careful of whether there are sharp objects.” Before each test begins, Jiang Tao always reminds you repeatedly.
In the detection, the strength of the fluorescence signal of the pathogenic gene directly affects the determination of the detection results. If there are suspicious phenomena such as the detected fluorescence curve signal is low or there is only a single target, Jiang Tao will convene personnel to conduct comprehensive analysis and judgment, and if necessary, repeat the test for review to ensure that the results can stand the test.
”A false positive will cause healthy people to isolate and become infected with the patient; a false negative will cause real patients to be treated. Life is a matter of no problem,” said Jiang Tao.

In accordance with the prevention and control requirements, the nucleic acid test result must be completed within 24 hours after receiving the pharyngeal swab sample. In order to let the hospital know the results as soon as possible to treat patients, nearly 100 samples were pre-treated from a batch of nearly 100 samples.>Komiks 1960 witch cloth draw to Babaylan 1990 cloth draw inspection was completed. Jiang Tao led the team to compress the time to within 4 hours by optimizing the process combination, achieving the ability to complete nucleic acid extraction of more than 90 samples within one hour and a single-day sample detection capability of more than 500 people.
”The team’s testing is efficient and fast, and the results are accurate, which greatly alleviates the pressure on our epidemic prevention and control sample testing.” The Wuhan Center for Disease Control and Prevention highly praised this.
Fast response during wartimeBabaylan 1990 clothes draw and work is carried out in an orderly manner, all thanks to Jiang Tao’s solid academic foundation and rich practical experience.
”Babaylan 1990 cloth drawJiang Tao is a versatile.” Academician Chen Wei, head of the Military Medical Expert Group, commented.
Jiang Tao has successively presided over and participated in the separation of pathogenic etiology such as SARS infection cases, H7N9 infection cases, Zika infection cases, etc., participated in the development of dengue fever vaccines and SARS vaccines, established a pathogen isolation technology platform, nucleic acid detection technology platform and pathogenicity and transmission risk assessment platform for a series of infectious diseases, and provided important technical support for the prevention and control of infectious diseases.
Respiratory infectious diseases are characterized by rapid transmission, wide coverage and high harm. It is crucial to have effective early diagnosis and prevention and control. After years of scientific research, Jiang Tao’s team took the lead in establishing our army’s first monitoring and early warning system for acute respiratory infectious diseases, and built a four-level monitoring and testing system for the entire army. The series of technical specifications compiled by the presidency were used throughout the army, greatly shortening the detection and screening time of respiratory epidemics.

Jiang Tao not only participated in the security tasks of a series of major domestic activities, but also went to Africa four times to Liberia, Sierra Leone and other countries to carry out medical assistance tasks.
In 2015, in order to prevent and control the Ebola epidemic, Jiang Tao went to Sierra Leone for the second time with the mobile laboratory testing team to assist in Seychelles. The testing team led by him passed the World Health Organization’s laboratory parallel capability assessment with full scores.
2018Cinema 1950 witch cloth draw, Jiang Tao led the pathogen monitoring team to participate in a special simulation test by an international organization. In the virus testing module, the team successfully accurately detected monkeypox virus, vaccinia virus and other pathogens in simulated samples filled with impurities, and accurately determined the strain, achieving excellent results with full marks.
Improving the accuracy of clinical diagnosis of Babaylan 1990 cloth draw
When he came to Wuhan, in addition to carrying out testing work, Jiang Tao also used his professional expertise in the research field to lead the testing team to screen other common respiratory infectious diseases in clinical samples.
Komiks 1960 witch cloth draw ”In the suspected and confirmed cases of new coronary pneumonia, whether there are other respiratory virus infections or co-infections, this is of great reference value for precise prevention and control and clinical treatment.” Researcher Cao Wuchun, deputy head of the Military Medical Expert Group, said.
Exploring deep-seated virus transmission and pathogenic mechanisms is the key to defeating the epidemic. Jiang Tao led a team to continue to conduct sequencing analysis for the novel coronavirus detected in clinical samples.
Cinema 1950 witch cloth draw With the development of the virus epidemic, whether the genomic sequence has mutated and the characteristics of the mutation are Babaylan 1990 clothes draw; in which areas and what impact is, Jiang Tao and his team are tirelessly studying and exploring.
In order to accelerate the effective integration of scientific research and clinical practice, Jiang Tao’s military medical expert group creatively used viral nucleic acid detection, antibody detection, multiple pathogen detection, and whole genome sequencing, the diagnostic chain to accurately diagnose new coronavirus infection or other pathogen infection in clinical patients, and was also used in the Optical Valley Campus of Hubei Maternal and Child Health Hospital, Taikang Tongji Hospital and other hospitals in Wuhan, effectively improving the accuracy of clinical diagnosis.
Forgot his family when he was ordered. After the epidemic is over, Jiang Tao plans to accompany his family. He and his wife agreed that when the epidemic is over, they will take their wife and children to visit Wuhan again to see what everything looks like after it returns to normal, to see the Wuhan Yangtze River Bridge and the Yellow Crane Tower, and to talk about their experience in fighting the epidemic in Wuhan.
The epidemic is immortal and the charge continues. This is Jiang Tao, a warrior who fights the epidemic.
