There are some disadvantages in internal medicine practice teaching now. To find a new teaching model

and implement a teaching reform is the key to improve teaching quality. We try to apply the case introduction to the teaching method of evidence based practice in the department of internal medicine. The new teaching model which combined case base study with evidence-based medicine in internal medicine practice can help put forward questions and guide students to analyze questions by the case. It also helps find evidence and solve questions by evidence-based method. The organic combination of the two

not only can stimulate students' learning enthusiasm and initiative

de-velop the correct clinical thinking

but also can effectively promote students' self-learning ability to update their knowledge. It is worth widely developing in internal medicine practice.
