Objective To investigate the effects of losartan on unstable angina (UA).Methods In a period of 14 days, 83 subjects with UA were randomly divided into 2 groups (group T and C). In group C, nitroglycerin 10-20mg plus 5%glucose 250ml was given by vein drips twice daily. Aspirin 150mg/day and metoprolol 12.5～25mg twice daily were given too. In group T, losartan, in a single dose of 50mg/day was given in addition to treatments of group A. Frequency of angina pectoris, rate pressure product, ST segments changes in 12 lead ECG and several heart function indexes in echocardiography were investigated at the beginning and the end of the study.Results The differences of efficacy between the two groups were significant ( P

Objective To investigate the experience of surgical treatment of primary extraperitoneal pelvic neoplasms,in order to improve tumor resection rate and safety.Methods The clinical data of 29 cases of primary extraperitoneal pelvic neoplasms were retrospectively analyzed from 1995 to 2013.To evaluate tumor resection preoperatively by CT,MRI and three dimensional reconstruction (3 d) medical technology,5 cases of preoperative interventional vascular embolization,intraoperative 2 cases in the iliac artery ligation,2 cases of intraoperative temporary blocking abdominal aorta.Intraoperative combined a variety of surgical approach to remove the tumor.Results Twenty-nine cases of patients,11 underwent tumor resection,5 underwent tumor resection and rectum resection plus sigmoid colostomy,the structure of 4 underwent tumor resection and repair damaged + sigmoid colon rectum temporary colostomy,3 underwent tumor resection and bladder partial nephrectomy,4 underwent tumor resection and uterine ovarian resection,2 underwent tumor resection + tail sacral tumor resection.25 patients recover well after the surgery,complications of 4 cases:intestinal obstruction in 2 cases respectively,pelvic abscess in 1 case,lower limb venous thrombosis in 1 case,cured by conservative and interventional therapy.No operative mortality and incidence of complications was 13.8％ (4/29).Conclusion Pelvic tumor preoperative imaging evaluation,combined incision and multi-visceral resection,fractional resection and recurrence after resection is the effective examination and treatment.
