To study the safety and feasibility of Mifepristone combined with Misoprostol terminating early pregnancy after cesarean section, mifepristone combined with misoprostol was used to terminate early pregnancy in 188 women requesting medical abortion. Among them, 27 cases were uterine cicatrix. The results showed that the complete abortion rate in 188 cases was 91.48 % after administration, that in 27 cases of unterine cicatrix was 100 % and that in 161 cases of no uterine cicatrix was 90. 06 % (P>0. 05). There were no differences in the duration of vaginal bleeding and time from the Misoprostol intake to the expulsion of gestational sac and chorionic villi between the two groups (P>0. 05). It was suggested that combined administration of Mifepristone and Misoprostol to terminate early pregancy is safe and effective after cesarean section.

Objective To study the clinical features of traumatic mitral regurgitation and its surgical treatment methods and outcomes. Methods Clinical data of 16 patients with traumatic mitral regurgitation surgically treated from December 2000 to November 2008 were retrospectively analyzed. The cardiac thoracic ratio was 0.55 ±0.07 and the left ventricular ejection fraction (LVEF) was (51.2% ±23.2)%. According to the New York Heart Association (NYHA) functional classification, 10 patients were at grade Ⅰ - Ⅱ before operation. The surgical procedures consisted of mitral valvuloplasty in 14 patients and mitral replacement in two, when correction of other cardiac injuries was made at the same time.Of all, 14 patients obtained follow-up for (35.2 ± 25.7 ) months. Results The interval between trauma and appearance of mitral regurgitation was (23.3 ±50.90) months. Of 13 patients with echocardiography during follow-up, there were four patients with normal tricuspid hemodynamics, seven with trace tricuspid regurgitation and two with mild regurgitation. The value of LVEF was (66.8 ± 9.0)% at followup, significantly higher than preoperation (P < 0. 05 ). There were 13 patients at grade Ⅰ - Ⅱ of NYHA,with a significant increase compared with preoperation ( P < 0. 01 ). Conclusions Mitral regurgitation may emerge either immediately or several years after trauma. Traumatic mitral regurgitation patients can get satisfactory outcomes when comprehensive mitral valvuloplasty or mitral replacement is performed promptly.
