Abstract: Problem-based study (PBL) combined with case-based study (CBS) teaching mode is a clinical case-centered and group discussion-focused modern teaching method aiming at improving postgraduate students’ clinical thinking ability. After teacher explaining knowledge points, showing cases and then organizing group discussion followed by analysis and summary, we tried to find students’ reaction when facing real clinical cases, to explore their way of thinking and then to judge their final disposition in order to figure out how they went wrong and how to correct it correspondingly. Whose meant to help students understand and apply better the knowledge they have leant from books and let them show more certainty to some important procedures of treatment, accompanied with their accumulating clinical experience.
