Objective To analyze the clinical features,diagnosis and treatment of gastrointestinal stromal tumors(GIST).Methods The clinical data of 45 patients in Zhenhai Second Hospital of Ningbo were collected and analyzed retrospectively.Results Among the 45 cases,25 cases had gastrointestinal bleeding,20 cases had abdominal pain and bloating,7 cases had incomplete intestinal obstruction and 22 cases had anemia.All patients underwent surgery.According to postoperative pathology,25 cases were benign,13 cases were borderline,and 7 cases were malignant.Patients were followed up for 2 to 4 years.3 patients died of tumor recurrence and metastasis.one case recurred 24 months after surgery and underwent a secondary surgery.Conclusions The diagnosis of gastrointestinal stromal tumor depends on pathology.Surgery is currently the most important treatment.Molecular targeted therapy for gastrointestinal stromal tumor therapy has some secondary significance.

Objective To understand the cognitive level of urban and rural general practitioners in the concept, diagnosis and treatment of chronic obstructive pulmonary disease and to provide the basis for continuing medical education in basic level hospital for all general practitioners. Methods General practitioners from 21 urban community health service centers (group A) and 27 of the rural community health service centers (group B) were surveyed on chronic obstructive pulmonary disease knowledge through a anonymous questionnaire, the survey contents included five aspects of chronic obstructive pulmonary disease such as basic concept, diagnosis, grouping diagnosis, treatment on stable phase and acute exacerbation. Results The correct rates of five questions in group A were 25.89%, 17.26%, 5.58%, 4.06%, 18.78 and in group B were 8.97%, 8.55%, 5.13%, 4.27%, 17.52%. In chronic obstructive pulmonary disease concept and diagnosis, there was significant difference between two groups(χ2=21.99, P<0.05 and χ2=7.41, P<0.05) . Conclusion The level of the cognitive of COPD (chronic obstructive pulmonary disease) among the general practitioners is very poor, and is strong against to the management work of chronic obstructive pulmonary disease. We need more continuing medical ed-ucation on "the guidelines on diagnosis and treatment of chronic obstructive pulmonary disease " among the urban and rural general practitioners.
