Celebration of the 99th anniversary of the founding of Henan Medical University Seminar (hu-bbs) was held in the conference room on the second floor of the College of pharmacy for the first time. Professor Duan Shaofeng, Yellow River scholar of Henan University, was invited to give a thematic report entitled "improvement and evaluation of drugs based on hyaluronic acid", which came from the College of pharmacy, School of life sciences, School of basic medicine, School of Stomatology, School of mathematics and statistics, School of software and National Institute of antibody drug development technology More than 40 experts and scholars from joint engineering laboratory, national and local joint engineering research center of nano hybrid materials application technology and other scientific research institutions Shared Academic feast with the online experts and scholars, and enhanced the friendship among interdisciplinary scholars in academic discussion.

At the beginning of the conference, the dean of the school of pharmacy warmly welcomed experts and scholars from other universities and different disciplines. He hoped that the experts and scholars would give full play to the multidisciplinary advantages of comprehensive universities, care for and support the school of pharmacy, establish a frank and friendly cooperative relationship with experts and scholars of the school of pharmacy, promote the innovation and development of pharmaceutical research through interdisciplinary integration, and work together to achieve more achievements at home and abroad High quality original and landmark achievements with high influence.

Professor Duan Shaofeng obtained his doctorate from New Mexico State University in 2007, and then did postdoctoral research in the University of Kansas. He has a broad academic vision and high academic standard. Focusing on the international academic frontier, Professor Duan made academic reports mainly from three aspects: "progress based on hyaluronic acid carrier", "research work related to hyaluronic acid carried out by our research group" and "research work planned to be carried out in the future". He used many articles related to the research of hyaluronic acid carrier to tell you the research progress of hyaluronic acid carrier. As a carrier, hyaluronic acid can be linked with drugs through chemical bonds to form conjugates to achieve targeted drug delivery, so as to play the anti-tumor role of drugs. It can also be combined with other organic materials or inorganic nano materials to form a new drug delivery system. Hyaluronic acid can also form hydrogels for medical and cosmetic applications. Duan Shaofeng described the research work of his research group, using hyaluronic acid as the carrier to connect hydrogen sulfide donor drug (adtoh), increasing the water solubility of adtoh, playing an anti-tumor role as an exogenous hydrogen sulfide donor; using hyaluronic acid as the carrier to prepare artesunate nanoparticles and play an anti-tumor role; the most interesting thing is that hyaluronic acid rutin has a very strong antibacterial and anti-inflammatory effect It has a very good transformation prospect. At the end of the report, Duan Shaofeng introduced the work to be carried out in the future: first, the preparation and research of drug nanoparticles based on hyaluronic acid; second, the construction and research of new drug loading system based on hyaluronic acid. He sincerely welcomes experts and scholars from different disciplines to carry out interdisciplinary research.

In the discussion stage, Dr. Wang Yaohui from the school of basic medicine, Dr. Wu Dongdong from the school of Stomatology, Dr. Cao Gengsheng, Dr. Zhang Biao and Dr. Wei Jianshe from the school of life sciences and other experts and scholars attended the meeting to deeply discuss their research fields with Dr. Duan Shaofeng. Duan Shao Feng has fully communicated with the experts about the "hyaluronic acid as a carrier, how to detect its targeting", "the effect of the number of repeats on the two carbohydrate units in hyaluronic acid on its effect", "the biological evaluation of hyaluronic acid loaded nanoparticles into the body" and "the effectiveness of hyaluronic acid mask and other beauty products". There was a heated discussion and a strong academic atmosphere.

"HU-BBS" is a high-level talent networking activity with academic exchanges as the carrier, aiming at "enhancing friendship among scholars, promoting academic innovation, and promoting the construction of" first class ". Since the opening of the first phase on June 27, 2019, 18 sessions have been held. Wang Yanming, Ji Shaoping, Zhou Shutang and other well-known experts and scholars have been invited to give lectures, and have conducted in-depth discussions and exchanges with nearly 1000 experts and scholars from different fields of medicine, biology, mathematics, physics, chemistry, pharmacy, materials science, computer science and technology, software engineering, etc The sparks of innovation are frequent. What's more gratifying is that many experts and scholars from different disciplines have established friendly and cooperative relations because of the afternoon tea party. A number of "x + medicine" cultivation projects hosted by non-medical experts have been launched. A large number of NSFC projects focusing on multi-disciplinary research on medical problems are on the rise. A "clinical problem oriented" medical science and engineering integration research and innovation team is being prepared …… At the 1st Anniversary time, the WeChat official account of Henan University biological medicine afternoon tea club was officially launched and operated. It will serve as a leading expert in making friends at home and abroad and creating a strong academic atmosphere in Henan University.

Duan Shaofeng, Ph.D., is a Yellow River scholar of Henan University, Professor of College of pharmacy, and postgraduate supervisor. In November 2007, he received his Ph.D. in organic chemistry from New Mexico State University, and then worked as a postdoctoral and researcher in the Department of chemistry and School of pharmacy of the University of Kansas. He has published about 50 papers in international core journals such as advanced materials, cancer letter, advanced functional materials, biomaterials, nanoscale and materials chemistry frontiers, and has applied for 7 invention patents. As reviewer of more than 10 international core journals such as Acta biomaterialia. He is now the vice chairman of the pharmaceutical preparation special committee of Henan Pharmaceutical Association and the director of the International Joint Laboratory of pharmacodynamic material basis of Henan University. At present, the research direction is pharmaceutical chemistry, pharmaceutical polymer materials, drug delivery, and the molecular mechanism of hydrogen sulfide in the occurrence and development of tumor, anti-inflammatory, antioxidant and other diseases.
