Abstract: With rapid society development and the constant changes in people's thinking， the medical ethics issue has become more prominent. Medical interns are often facing ethical problems in clinical practice. Due to the lack of understanding of the experience in medical ethics， they often handle the problems poorly， which leads to intensified disputes between doctors and patients. The paper discusses some ethical problems that often appear in the clinical practice of internal medicine， and suggests several methods to improve the medical ethics education of interns in the clinical process.
