Objective To investigate the clinical characteristics, diagnosis and treatment of placenta increta.Methods A retrospective analysis was carried out on 13 admitted cases of placenta increta from 1989～2006. Results Among the 13 cases analysed, 5 cases with a history of Caesarian section had a 0% success rate of treatment with conservative care (0/5), 100% less than that of cases with no history of Caesarian section (8/8), P＜0.05; the success rate of treatment of partial placenta increta with methotrexate with Jia Wei Sheng Hua Tang was 100%. Conclusion Caesarian section is a risk factor of placenta increta, and its prognosis is poor; however, Jia Wei Sheng Hua Tang has proven satisfactory as a supplementary treatment for placenta inereta.

Objective To evaluate the effectiveness and safety of leuprolide acetate in the treatment of endometriosis. Methods From Nov. 2007 to Oct. 2012, the patients who confirmed to be endometriosis were randomly divided into test group of 113 cases and control group of 116 cases. The test drug was the sustained-release agent of leuprolide acetate. The control drug was Enantone. The drugs were used for 3 times in total. After treatment, the ovarian mass volumes measured with type-B ultrasound, the scores of the patient′s subjective symptoms during non-menstrual and menstruation days, the pelvic signs during non-menstrual days, the changes of hormones [estradiol (E2), FSH, LH], and adverse events were observed. Results After the treatment, the rate of changes of ovarian mass volume (among them, at 12 weeks after the first injection, the median was -55.83% in the test group, -68.22% in the control group, P=0.336), the distinct improvement rate of symptom scores and pelvic signs during non-menstrual days [among them, at 12 weeks after the first injection, the rate of lower abdomen pain was 47.5%(48/101) in the test group, 44.0%(44/100) in the control group, P=0.881], the hormone (E2, FSH, LH) levels [among them, at 12 weeks after the first injection, the serum level of E2, was (33±38) pmol/L in the test group, (38± 40) pmol/L in the control group, P=0.414;the serum level of FSH, was (5.1±2.8) U/L in the test group, (5.3± 2.3) U/L in the control group, P=0.666;the serum level of LH, was (0.6±0.8) U/L in the test group, (0.6±0.9) U/L in the control group, P=0.907], had no statistically significant difference between the two groups (all P>0.05). The distinct improvement rate and improvement rate of symptom (lower abdomen pain, low back pain) scores during menstruation days at 12 weeks after the first injection, the rates of lower abdomen pain were 73.9%(34/46), 15.2%(7/46) respectively in the test group, 72.3%(34/47), 2.1%(1/47) respectively in the control group, had statistically significant difference between the two groups (P=0.026). There was no serious adverse event occurred in both two groups. The incidence rate of adverse event was 33.6%(38/113) in test group, 23.2% (27/116) in control group, there was no significant difference between the two groups (P=0.082). Conclusion Leuprolide acetate is effective and safe in the treatment of endometriosis.

Objective To systematically evaluate the clinical effect of transcutaneous electrical acupoint stimulation(TEAS)on promoting postoperative gastrointestinal function recovery.Methods Randomized controlled trials(RCTs)related to postoperative gastrointestinal function using TEAS were re-trieved from the CNKI,WanFang,VIP,Embase,and PubMed database.RCTs on the effects of TEAS on postoperative gastrointestinal function were included.Methodological quality was evaluated using the quality evaluation tools recommended in Cochrane evaluation manual 5.1.Meta-analysis was performed using Rev-Man 5.3 and Stata 15.Results Thirty-four RCTs involving 3 593 patients were included.There were 1 781 patients in the TEAS group and 1 812 patients in the non-TEAS group.Compared with the non-TEAS group,the incidence of nausea(RR = 0.46,95%CI 0.36 to 0.59,P＜0.001)and vomiting(RR = 0.47,95%CI 0.37 to 0.59,P＜0.001)within 24 hours after surgery was significantly reduced in the TEAS group,and the postoperative recovery time of bowel sound(MD =-6.42 hours,95%CI-8.53 to-4.32 hours,P＜0.001),first exhaust time(MD =-8.72 hours,95%CI-10.64 to-6.80 hours,P＜0.001),andfirstdefecationtime(MD =-11.83hours,95%CI-14.67 to-8.98 hours,P＜0.001)were significantly shortened.Conclusion TEAS can promote postoperative gastrointestinal function recovery,significantly reducing the incidence of postoperative nausea and vomiting within 24 hours after sur-gery,and shortening the time of first anal exhaust and defecation after surgery.
