Objective To study the clinical diagnosis and therapy of scar pregnancy after uterine cesarean section.Methods Clinical data of 21 patients with uterine cesarean section in our hospital from June 2006 to December 2008 were retrospectively analyzed.Results The success rate of 16 cases by drug therapy (including three cases of surgical treatment) was 81.3%;3 cases of auto-discharge transferred to other hospitals to do intervention,1 case used expectant treatment,1 case used complete curettage of uterine cavity under B-Ultrasound.Conclusion Drug treatment can terminated scar pregnancy after uterine cesarean section effectively,but there is a potential risk of massive hemorrhage or uterine rupture;color doppler ultrasound,especially Transvaginal color doppler ultrasound was the primary means of cesarean section,and benefit to judge prognostic factors and observed treatment.

In order to give full play to the important role of multi-disciplinary treatment (MDT) in oncology teaching in talent training and discipline development, an oncology teaching and research section has been established, the textbook Clinical Oncology has been compiled, excellent teaching workers in affiliated hospitals have been selected to form an MDT teaching team, and a multi-tutorial system has been established for the discipline related to specific tumor types. The multi-tutorial system of disciplines combines lecture-based learning (LBL) with case-based learning (CBL) and problem-based learning (PBL). Students are arranged to observe and participate in clinical MDT consultation during the inter-class practice, and compared with the traditional assessment form, MDT case discussion questions, review writing, classroom simulation of the MDT process and real participation in clinical MDT discussions are added. The questionnaire for students who participated in MDT teaching showed that more than 93% of the students believed that the MDT teaching model was helpful for systematically mastering the knowledge of the chapters they had learned and understanding the cutting-edge progress, improving learning initiative, thinking and problem-solving ability, clinical comprehensive analysis ability and teamwork spirit. The majority of students' expression skills [89%(169/190)] and literature review skills [79%(150/190)] were improved; 94%(178/190) of students expressed their willingness to accept this teaching method. The teaching practice experience of the Department of Oncology of Jilin University based on the MDT model helps to improve the teaching level of oncology.
