A study the quantitative measurement of DNA content in 3 normal lacrimal glands, 18 pleo-morphie adcnomas and 21 lacrimal gland carcinomas was carried out by flow eytometry. The results showed that pleomorphie adenomas still had the characteristics of DNA content of the normal diploid lacrimal gland cells. The significant increase of DNA index (DI) in pleomorphie adenomas might mean malignant transformation. DNA content of malignant tumor increased evidently and its aneuploid ratio was higher than in pleomorphic adenomas (76.2% VS 16.8%) (P

ObjectiveTo understand the effect of student standardized patient-case teaching in orthopedic surgery.Methods A total of 120 clinical medicine students were selected,and they were randomly assigned to be research group ( n=60 ) and control group ( n=60 ),as students standardized patient,10 clinical medicine students and postgraduate students of orthopedic surgery were selected,and standardized patient-case teaching was applied to the students in research group while traditional case teaching was applied to students in control group.After teaching,the teaching effect and survey the feedback information about teaching form students were evaluated.ResultsTotal mark of effect evaluation of 2 groups is 83.50 + 6.55 and 71.11 ± 6.57,and both operational score and knowledge study achievements of research group were better than control group (P＜0.01),over 80％ research group students effect evaluation being positive.ConclusionStudent standardized patient-case teaching is helpful to improving students' study in orthopedic surgery and the teaching effect is remarkable.

Thrombospondin-1 expresses in a variety of tumors and induces endothelial cell apoptosis,thus inhibits tumor angiogenesis and prevents tumor growth.It function domain ( Type I sequence):3TSR,retaines the function of inhibit angiogenesis,has the certain practical significance in clinical cancer treatment.
