Self-introduction
My research focuses on bridging basic science with clinical application. In the field of basic research, I investigate the interaction between cancer and the tumor microenvironment, the mechanisms of anti-tumor chemotherapy, and drug repositioning. My clinical work centers on diseases associated with Non-helicobacter pylori Helicobacter (NHPH) infection, gastrointestinal malignant lymphoma, and the relationship between gastritis and carcinogenesis.
