Based on the partial knowledge of anatomy teaching for understanding of gastrointestinal bleeding [Keywords:] gastrointestinal bleeding, local anatomy, teaching Gastrointestinal bleeding is a common clinical emergency, but also the focus of clinical teaching and difficulties. In the process of teaching the subject, we localized anatomical knowledge-based and accurately determine the bleeding site, followed by the latest research advances with clinical, in order to achieve the most good teaching results. now teaching experience gastrointestinal bleeding following report. 1 to master accurately determine the anatomical knowledge of local bleeding sites Gastrointestinal bleeding is from the entrance to the anus into the esophagus gastrointestinal bleeding, the main clinical manifestations are vomiting blood, blood in the stool, and melena [1]. In clinical first visit, the gastrointestinal bleeding and further treatment to determine the clinical manifestation depends , due to the amount of bleeding and bleeding in different parts of the patient can have many manifestations. such as repeated vomiting, then vomiting occurs, Mallory-Weiss mostly caused vomiting suggest the bleeding site is located above the flexor ligament, melena that bleeding sites in the back cecum or more. In teaching, should have knowledge of local anatomy accurately determine the bleeding site, will be vomiting blood, blood in the stool, melena and characteristics one by one analysis, so that students can be judged based on the amount of bleeding and the general characteristics of the bleeding sites, to further determine the causes of bleeding . Meanwhile, the pseudo-gastrointestinal bleeding should be excluded, such as oral melena caused by bismuth. 2 application of the latest teaching diagnosis and therapy 2.1 Application of Evidence-Based Medicine Medicine EBM (evidence based medicine, EBM) refers to the careful, accurate and intelligent application of current available to the
