Abstract: Eight-year M.D. program has been widely developed in many universities and colleges in China, and has played an important role in training high-level medical talents. In recent years, Peking Union Medical College has carried out a new medical education program of "4+4" pilot class on the basis of the eight-year consistent mode. The General Surgery Department of Peking Union Medical College Hospital, in line with the educational system reform, has explored clinical internship teaching mode for students from "4+4" pilot class, according to the requirements of the curriculum and the actual clinical situation. The new teaching mode is effective in cultivating students' interest in learning, helping them to comprehensively understand surgical diseases, and laying a solid foundation for subsequent clinical practice, which has been initially recognized by medical students. This study introduces this teaching mode in detail in order to improve future clinical medical education.
