Among them, clinical medicine, dentistry, medical laboratory science and nursing are national specialties; eight-year clinical medicine (French class), eight-year clinical medicine (4+4 masters and doctoral degrees), five-year clinical medicine (pediatric direction) and five-year clinical medicine (English class) are the special classes of the college.

 

1. Construction of tissue-engineered tracheal cartilage rings using Collagen/PLCL porous nanoscaffold materials containing Kartogenin

Based on the characteristics of normal tracheal cartilage rings in human body, we use coaxial electrostatic spinning technology to prepare a new type of scaffold material with active substances, so as to provide a stable and efficient microenvironment for inducing bone marrow mesenchymal stem cells into chondrogenic rings, to improve the induction efficiency, and finally combine with stem cells to obtain a more ideal tissue-engineered tracheal cartilage ring, which provides new treatment ideas for tracheal stenosis patients and has a broad clinical application. Prospect.

Technological innovation points:

1. The use of Kartogenin (KGN)-induced bone marrow mesenchymal stem cells (BMSCs) in combination with novel scaffolding materials to construct tissue-engineered cartilage can be expected to provide a continuous and stable cartilage tissue and avoid endochondral ossification.

2. The use of coaxial electrostatic spinning technology to prepare collagen/caprolactone porous nano-scaffold material with KGN will provide a stable and efficient microenvironment for the induction of BMSCs into cartilage, which is expected to improve the induction efficiency and obtain more ideal tissue-engineered cartilage rings, providing new therapeutic ideas for the majority of patients with tracheal stenosis, with broad prospects for clinical application.

 

2. Application of 3D printing technology in the diagnosis of congenital heart disease in children

The application of 3D printing technology in the field of medicine has become a hotspot of research at home and abroad. Shanghai Children's Medical Center has the most advanced research center for 3D printing medical digitalization for children in China. 3D printed models can be used for interpretation, surgical planning and simulation, which will ultimately benefit patients.

3D printing technology is the most widely used tool for future clinical procedures. For complex surgeries such as congenital heart disease, physicians often need to visualize cross-sectional imaging data into 3D spatial images to design surgical plans. Nowadays, 3D printing technology can be used to plan the surgical plan on the physical model, and customize the surgical patch, catheter and surgical guide in advance. Ultimately, the goal of precision medicine can be achieved.

3D printing related research has been published in 6 statistical source journals. He has applied for 3 major research projects at the relevant bureau level, Shanghai Jiao Tong University medical-industrial intersection, and Shenkang. The research results have been presented in the Annual Meeting of Radiology in North America, the Annual Meeting of International Imaging Technology, the Annual Meeting of Chinese Imaging Society, and the Annual Meeting of Digital Medicine of Chinese Medical Association. He used the ATLAS algorithm to accurately segment and extract the mathematical model, and the 3D printed tracheal cartilage external stent developed by him has applied for a utility model patent and passed the examination of the Intellectual Property Office. He attended an advanced training course on 3D printing technology hosted by Academician Dai Kiron and received a certificate from the Engineering Research Center of the Ministry of Education.

 

3、Development and research of GNA002, a new anti-cancer targeted drug.

In order to develop highly effective and low-toxicity chemotherapeutic agents against certain types of malignant tumors and to improve the survival rate and quality of life of patients with malignant tumors, this project selected EZH2, a key protein in malignant tumors, as a drug target and developed a series of specific anti-cancer drugs.

Through a high content screening platform, we found that the natural product, boswellic acid, could directly bind to the target and specifically degrade the cancer protein EZH2. We further investigated the structure-efficacy relationship between GNA002 and GNA002 and synthesized a series of GNA002 derivatives. One of the most active compounds, GNA002, had significant growth inhibition effects on hematological tumors, lung cancer, breast cancer, cervical cancer, ovarian cancer and head and neck cancer, and showed excellent pharmacokinetic and toxicological experiments. GNA002 is a new, targeted, oral EZH2 specific inhibitor with a wide range of clinical indications and market prospects.

The innovative drugs have been patented in China; international patents have been granted in six countries or regions, including the United States and Japan.
