Based on an analysis of the problems emerged from a clinical course that uses English to teach selected chapters of Obstetrics and Gynecology for the students enrolled in a seven-year program in medical science,our paper proposes methods to improve the quality in teaching.The students need to strengthen English in medical areas and be well-prepaired before class.The instructor needs to improve English and make sufficient preparations for the teaching.These conditions are conductive to satisfactory educational effectiveness of teaching Obstetrics and Gynecology in English.

Clinical noviciate teaching in obstetrics and gynecology is an important component of China's higher education in medical sciences.It is necessary to strengthen the training of instructors,motivate students' interest in learning and adopt various types of teaching methods.These measures can improve the quality of clinical teaching in obstetrics and gynecology and enhance its educational effectiveness.

Objective:To investigate the relationship between the level of soluble Fas antigen(sfas) and soluble Fas ligand(sFasL) and endometriosis associated infertility.Methods:The sfas and sFasL level in sera and peritoneal fluid of infertile women with endometriosis were assessed with enzyme-linked immunosorbent assay,and were compared with those of 14 infertile women resulting from chronic pelvic infectious disease and 16 fertile controls.Results:The sFasL levels(175.09?80.50pg/ml in sera and 284.50?152.38pg/ml in peritoneal fluid) were significantly higher in infertile patients with endometriosis than those of infertile controls(88.47?43.55pg/ml in sera and 17.30?9.62pg/ml in peritoneal fluid) and fertile controls(16.13?11.75pg/ml in sera and 8.84?2.31pg/ml in peritoneal fluid).Compared with the levels of sfas in infertile women resulting from pelvic infectious disease(868.75?570.48pg/ml in sera and 181.76?157.78pg/ml in peritoneal fluid) and fertile control group(822.26?129.12pg/ml in sera and 318.42?145.16pg/ml in peritoneal fluid),the values of sfas in infertile patients with endometriosis(828.60?429.65pg/ml in sera and 349.6?288.89pg/ml in peritoneal fluid) have no significant difference.Conclusion:Endometriosis-related infertility has great association with the level of sFasL,and sFasL may play a key role in the local homeostatic regulation in endometriosis and in turn result in the development of its associated infertility.
