On the afternoon of November 14, 2022, the celebration of IAA Fellowship Day was held in Beijing. Prof. Han Hongbin, Director of the Institute of Medical Technology, Peking University Medical College and Peking University Third Hospital, was invited to attend and was awarded the certificate of new academician. Jean-Michel Contant, Secretary General of the International Academy of Astronautics (IAA), made a Report on the Work of the IAA online, and after introducing the winners of the IAA Von Karmen Award and the Laureus Team Award in 2022, Liu Jiyuan, former President of the International Academy of Astronautics (IAA) and Director General of the National Space Administration (NASA), and Bao Weimin, Academician of the Chinese Academy of Sciences (CAS) and Chairman of the IAA Division of Engineering Sciences, were presented with the The newly elected academicians were awarded certificates.

It is reported that the International Academy of Astronautics (International Academy of Astronautics), referred to as “IAA”, was founded by the world famous scientist and aerodynamics master Von Karmen in 1960, and was originally founded in Stockholm, Sweden, and is now headquartered in Paris, France. IAA has four academic departments, namely, Basic Sciences, Engineering Sciences, Life Sciences and Social Sciences, and the academicians of each department are co-opted once a year, and the candidates should be nominated by three academicians from different countries, and about one-third of the nominees will be elected after two rounds of voting. As of the current round of election, the total number of academicians from 86 countries has reached 1,178, of which 141 are Chinese academicians, fewer than the United States and Russia, ranking third in the world.

Attachment: Research direction and main academic achievements of Han Hongbin's team:

The Shen XII manned space mission opened a new chapter in China's astronautical career. The long time working and living in orbit puts forward new propositions and higher requirements for medical development. Microgravity is the most important threat to astronauts' long-time on-orbit navigation, and the extracellular gap is the main structural space where microgravity body fluid redistribution occurs. Because the width of the gap is only a few tens of nanometers, in vivo detection is difficult. The team led by Han Hongbin independently designed and developed a tissue channel measuring instrument, which successfully detected the ultra-early changes in the ultrastructure of the extracellular space under microgravity, and explained the structural basis of the changes and the mechanism of the changes, which provided a brand-new way of thinking for the protection of the aerospace brain. The research results were published on the occasion of the successful launch of Shen XII and the orbital flight of our astronauts, and were publicized on the official website of an internationally renowned magazine, and selected as one of the highlights of scientific discoveries in Chinese science and life science magazines. The extracellular space of the brain is known as the last high ground of brain structure research, which is an ultrastructural space that has not yet been fully recognized and exploited, and it not only provides the basic conditions for neural networks to work, but also is the necessary channel and place for drugs to work. Recent studies have also shown that the brain's extracellular space is closely related to sleep, cognition and sensory formation. In the past 20 years, Han Hongbin has led an interdisciplinary team to successfully break through the blind spots and technical bottlenecks of traditional measurement techniques, and utilized the new techniques and instruments designed and developed by him to discover a series of brain ultrastructural features and new laws, and to put forward the theories of brain partitioning homeostasis as well as new theories and methods of molecular regulation of the extracellular space; the new discoveries, techniques and theories have been applied to research in the treatment of brain diseases, development of new medicines, aerospace medicine, and other cutting-edge fields. The new discoveries and theories have been applied in the treatment of brain diseases, new drug development, aerospace medicine and other frontier fields. With Han Hongbin's team as the main force, China's cellular microenvironmental in vivo imaging and detection research team, the global academic influence in this direction has risen year by year, from 18th in the global rankings before 2016 to the world's No. 1 in the past five years.
