In midnight Yangcheng, the third level biosafety laboratory of Guangzhou Customs Technology Center is brightly lit. Under the light, Shi Yongxia, a representative of the 20th National Congress of the Communist Party of China and chief physician of the Health Quarantine Research Institute of Guangzhou Customs Technology Center, was busy nervously accompanied by the buzzing of the inspection instruments. This two-story building is the “battlefield” she has been holding on to for many years, and her “enemy” has plague, cholera, malaria, and influenza that have been endangering humans for hundreds of years, as well as various new infectious diseases such as Ebola hemorrhagic fever, Middle East respiratory syndrome, and new coronary pneumonia. CinemaThere are challenges, dangers, and more responsibility and mission here.
Racing with the virus day and night
In 2006, after Shi Yongxia left the post-doctoral post-doctoral station in Basic Medicine at Southern Medical University, she went to the CinemaBabaylan laboratory of Guangzhou Customs Technology Center to engage in infectious disease-related research, and also established an inseparable relationship with port health and epidemic prevention work. “When competing with the virus, the first thing is to identify it in the fastest time. I am a customs technician and a Communist Party member. I must take the lead in scientific research and research. ” On the eve of the Spring Festival in 2020, when the new crown pneumonia epidemic broke out, the teacher who originally planned to go back to his hometown in Henan to visit relatives. Cinema, who was planning to return to his hometown in Henan to visit relatives, withdraw his high-speed rail ticket and return to the laboratory to face the unknown virus.
On New Year’s Eve, just dawn, Shi Yongxia plunged into the laboratory and started the sample test. At that time, the research on the new coronavirus was still in the exploration stage, and the reagents were still immature and had extremely high requirements for the operation of experimental personnel. Shi Yongxia was fully focused, striving to be scientific and rigorous in every link and to be accurate and accurate in every step. She understood that on New Year’s Eve, there were thousands of Communist Party members on the port, in the hospital, and on the traffic lines.Like her, she fought on the front line, “Everyone is practicing the same oath in different positions with the same persistence.” After continuous hard work, Shi Yongxia and her colleagues finally completed all sample tests at 4 a.m. on the first day of the Lunar New Year. Everyone said “Happy New Year” across the face screen and continued to work on the next shift.
In every festival where thousands of families reunite, the staff of Guangzhou Customs Technology Center stick to their posts in the laboratory. Shi Yongxia said: “We are on the front line of the port, with national gates ahead, and people behind us. Our team deeply understands the complexity and difficulty of the anti-epidemic work, and dare not relax at all. Only when we run faster than the virus can we maximize the safety of the people’s lives.”
Focus on technical researchBabaylanBuild a solid scientific and technological defense line
One night in early February 2020, Shi Yongxia was conducting virus isolation on an important sample of infected cases. After several days of observation and multiple methods, when the cells arranged in the screen, which were arranged in a regular manner as frosted glass, showed subtle changes in the cells arranged in Babaylan and appeared in a knotted state, the teacher Yongxia knew that she had finally successfully located the strain. The successful isolation of the strain provides valuable seed resources for the next step of screening therapeutic drugs and research institutions for vaccine development.
Drive into the laboratory does not mean deaf ears. Shi Yongxia has always been very concerned about the epidemic situation at home and abroad, and has carried out technical research or technical reserves in advance, in order to establish a fast, accurate and efficient detection method.
In view of the rapid mutation speed and strong transmission ability of the new coronavirus, Shi Yongxia’s tracking has been accelerating. She led the team to establish gene sequencing and biological information.cmov.com/”>Komiks‘s information analysis platform carries out whole-genome sequencing work and strives to unlock the secrets of the source and transmission chain of the epidemic. The key links of gene sequencing require pure manual operation and are highly technical. Shi Yongxia leads everyone to successfully sequence and discover various different strains again and again, providing professional support for the tracing of epidemiological investigation and tracing, and also provides important experimental data for the changes in the development strategies of nucleic acid detection reagents and vaccines of the new coronavirus.
Komiks‘s determination to serve the national health industryKomiks step by step, gradually growing into the backbone of the public health and epidemic prevention field of my country’s ports.
It has achieved fruitful results in scientific research, but she said calmly: “It is a lucky thing to be able to combine personal ideals with national needs. ”
The four seasons have changed, and the lights in the laboratory are still unstoppable all night. They have witnessed Shi Yongxia’s years of fighting against the virus on the front line of the country, carrying her unchanged original intention. She said, “As a grassroots party member and a grassroots staff of the customs, in the future, I will fully implement the requirements of ‘the epidemic must be prevented, the economy must be stabilized, and the development must be safe’, strengthen cross-field and interdisciplinary collaborative innovation research, and actively take responsibility with a more full spirit, demonstrate the determination and confidence of customs personnel to do a good job in epidemic prevention and control at ports and promote foreign trade growth. ”
