Entering the entrance of the Biological Shock Tube Laboratory at the Army Medical University, what catches the eye is a steel "dragon" about 39 meters long. This is a biological shock tube built by a team led by Wang Zhengguo, a famous field surgery expert and an academician of the CAE Member. It can simulate shock waves generated by explosions at different yields and distances. Although the device was developed in the 1980s, its technological level is still at the forefront internationally. On January 5th of this year, Academician Wang Zhengguo passed away in Shanghai due to illness at the age of 89. After his death, in accordance with his will and the wishes of his family, his body was donated to the Naval Medical University, making the final contribution to the medical cause. I am not dusk, I am sunrise. I will work as long as I can Wang Zhengguo once said that from his head full of green hair to his white hair swaying, and even to the end of his life, he always maintained his loyalty to the Party and pursuit of science. In the 1960s, as the world entered the Cold War era, research on the protection against atomic bombs gradually emerged. The energy released instantly during an atomic bomb explosion generally causes burns, impact injuries, and radiation damage to the human body. In terms of lethality and range of damage, impact injuries caused by shock waves rank second. Research on the prevention and treatment of impact injuries has become an urgent need for the country and the military. At that time, under the leadership of the "father of impact injuries" Richmond, the research on impact injuries in the United States had already become far ahead of the world. In 1970, Wang Zhengguo obeyed organizational arrangements and was responsible for the research on impact injuries. Previously, he had been engaged in research on burn compound injuries for more than ten years and had achieved considerable results. Some colleagues advised him, "Old Wang, don't do this research. Impact injuries have little research value because if it's a serious injury, it can't be treated, and if it's a minor injury, it doesn't need to be treated." "With such a large army in China, how can there be a gap in the field of impact injury research?" Wang Zhengguo resolutely decided to accept this task. At that time, the experimental conditions were very rudimentary, there was not a decent instrument, there was not enough funding, and there were very few reference materials available. Faced with these situations, Wang Zhengguo did not give up. He entered the nuclear explosion zone 8 times and went to chemical explosion tests and accident sites more than 10 times to observe the injury phenomena caused by various explosives, investigate and collect first-hand information on impact injuries, and conduct a large number of experiments. He repeatedly explored the killing effect, dose effect relationship, and safety standards of shock waves, explored the laws and mechanisms of impact injury occurrence, and laid the foundation for research on impact injuries. As he gained a deeper understanding, Wang Zhengguo realized that researching impact injuries required the development of his own biological shock tube. Therefore, he made up his mind to solve this problem. In 1984, with the cooperation of the Institute of Mechanics of the Chinese Academy of Sciences, Wang Zhengguo and his colleagues successfully developed the first biological shock tube in China, which solved the problem of conducting blast injury research in the laboratory for the first time. Subsequently, they successively developed small and medium-sized biological shock tubes, forming a series of biological shock tubes. According to the data, this equipment can simulate the shock waves generated by nuclear and explosive explosions in a more realistic manner, and can simultaneously simulate the positive and negative pressure of the explosion waves, with smooth and neat waveforms. At that time, the explosion wave simulated by American research institutions only had positive pressure, not negative pressure, and its simulation effect was relatively poor. In 1988, Richmond came to China. Previously, he had only seen the name "Wang Zhengguo" in Chinese impact injury research results cited in US military textbooks. After visiting Wang Zhengguo's laboratory and listening to his work introduction, Richmond was full of praise and immediately invited Wang Zhengguo to attend an international academic conference to be held in the United States the following year. In 1992, Wang Zhengguo, as the first person in charge, won the first prize of the National Science and Technology Progress Award for the development and application of a series of biological shock tubes.
