On July 18, the "Special Seminar on Major Projects in Frontier Medical Technologies" hosted by the Health Data and Digital Medicine Branch of the China Association for International Exchange of Healthcare and the Institute of Medical Technology of Peking University Health Science Center was successfully held in Hangzhou. Professor Han Hongbin, Corresponding Fellow of the International Academy of Astronautics and Dean of the Institute of Medical Technology of Peking University Health Science Center, attended the seminar and delivered a welcome speech.

Professor Han Hongbin warmly welcomed the arrival of all the experts and introduced the background and significance of this forum. He said that the detection and treatment regulation of neural network microenvironment information as a frontier field in the development of brain science has important research value and application prospects. He hoped that through the periodic reports in this forum, academic exchanges and cooperation in this field can be promoted, and the innovation and development of derivative projects and technologies can be promoted.

Professor Han Hongbin delivered a welcome speech

The seminar invited a number of experts and scholars with rich experience in the field of neural network microenvironment information detection to give keynote speeches. The meeting was hosted by Associate Researcher Sui Yao from Peking University and Assistant Researcher Li Hongfeng from Peking University Health Science Center. Associate Researcher Lu Yanye from Peking University Health Science Center shared a report on the theme of "Neural Network Scientific Research Collaboration Management Platform Integrating Brain Extracellular Space", and introduced the platform in detail from the architecture layer, algorithm layer, data layer, physical layer, and software layer. With multimodality and cross-scale as the core design goals, the collection and management of structural and functional data are carried out, and the intersection and sharing of medical data are gradually realized. It is expected that a scientific workflow system and model analysis platform will be introduced later. As the person in charge of the first major project, Researcher Xie Zhaoheng from Peking University Health Science Center gave a keynote report on "Progress in Cross-Scale Imaging of Brain Ultrastructure", introducing the latest technologies and research results in the collection and processing of brain extracellular space structural information. Through the acquisition, quantitative analysis, mathematical modeling and corresponding database construction of imaging information across scales and fields of view such as FIB-SEM, cryo-electron microscopy and soft X-ray, the nanostructure of the extracellular space is obtained, and it is expected that a brain-like model integrating the extracellular space can be constructed through structural information, thereby revealing the rules of molecular transport, which provides important support for revealing the microstructure and function of the brain. As the person in charge of the second major project, Sun Jianfei, a researcher at Southeast University, shared a report on "Progress in the acquisition and analysis of brain ultrastructure functional information". By using responsive probes to measure functional information, molecular probes and nanoprobes such as optical, magnetic, radionuclide molecular probes and optical and magnetic functional composite probes have been developed, which have significant advantages in the study of brain tissue interstitial fluid drainage. By establishing an algorithm for cross-scale multimodal image registration, the information fusion of optical microscopy, electron microscopy and X-ray imaging under the same field of view is achieved. Through the acquisition and analysis of ultrastructure functional information, new possibilities are provided for the diagnosis and treatment of neurological diseases. As the person in charge of the third major project, Professor Zhang Jicong of Beijing University of Aeronautics and Astronautics shared a report entitled "Progress in the study of precise neural regulation through the extracellular space". It introduced in detail the progress of magnetoelectric system and optoelectronic system in three-chamber information synchronous acquisition and cross-scale imaging technology, the development of molecular transport regulation methods in the extracellular space and new brain function imaging methods, so as to construct a neural biological network integrating the extracellular space, in order to effectively improve the treatment effect of nervous system diseases in the future. Lian Jingge from Professor Han Hongbin's team, as the backbone of the fourth major project, shared a report entitled "Research Progress of Brain Disease Treatment through Extracellular Space", which detailed the application of extracellular space in brain disease treatment and its research progress. By comparing the structural and functional information of normal and brain diseases, a system logic architecture integrating multiple information such as application layer, algorithm layer, and data layer is established, so as to achieve accurate diagnosis, targeted delivery and treatment of brain diseases.
