Objective To evaluate the advantages and disadvantages between transabdominal myomectomy(TAM)and laparoscopic myomectomy(LM).Methods We were trospectively reviewed the clinical data of 35 cases of TAM and 30 cases of LM,analyzed adaptation,complication,bleeding quantity and recover time.Results Every patients operated successful.The operation time of LM group was longer than TAM group.The bleeding quantity,recovery time and post-operation in-hospital days of LM group were all shorter than TAM group.Conclusions Laparoscopic myomectomy have advantages of micro invasion,rapidrecovery,less in-hospital days and less complication.

Objective To analyse the dianosis and treatment process in suspicious ectopic pregnancy(67 cases)and explore the value of diagnostic curettage in suspicious ectopic pregnancy.Methods Elect ectopic pregnancy cases in conservative treatment(67cases),divide these cases in two group as the diagnostic curettage group and the control group in random and analysis their success ratio in conservative treatment;time in hospital;expense in treatment.Results The success ratio in conservative treatment were similar in two group ;the time in hospital and expense in treatment was significant lower in diagnostic curettage group.Conclusions Diagnostic curettage was useful in differential diagnosis of suspicious ectopic pregnancy;It can reduce the time in hospital and the expense in treatment.

Objective To evaluate the training quality of junior college graduates of clinical medicine based on the feedback from the graduates and their employers.Methods Totally 112 junior college graduates tailored to rural areas among all the three years' graduates were selected.These graduates and their employers were asked to do the questionnaire and discussion.Results The overall evaluation from the graduates on the school curriculum and teachers was good,with satisfactory rate being above 95％.The employers had nice impression on the graduates and spoke highly of them,with satisfactory rate reaching 97.4％.Of all the three years' graduates,one-time passing rate in the qualification examination for assistant practitioners came to 41.0％,much higher than the average passing rate of 20.12％ in the same area and at the same time.Conclusion The teaching effect for junior college graduates of clinical medicine tailored to rural areas is satisfactory and the reform on teaching is worka ble and effective,however,it needs further practice.

Objective To explore the optimal time for clinical interventions on full-term or nearterm pregnant women with premature rupture of membranes(PROM). Methods A retrospective study was conducted on clinical data of 903 healthy, full-term or near-term (gestational age ≥ 35 weeks), singleton pregnant women with PROM, who admitted to our hospital from January 1, 2005 to December 31, 2009. All subjects were divided into 6 groups: women in group 1 were those fell into spontaneous labor within 6 h after PROM (n=269, 29.8%); women in group 2 were in spontaneous labor between 6 to 12 h after PROM (n= 161, 17.8%) ; women in group 3 were in spontaneous labor at 12 to 24 h after PROM (n = 75, 8. 3%); In group 4 oxytocin was administered for induction for women not in labor at 6 to 12 h after PROM (n= 124, 13.7%) ; Group 5 included those women who were not in labor at 12 to 24 h after PROM and oxytocin induction was offered (n=98, 10. 9%);Group 6 consisted of those women who were not in labor over 24 h after PROM and oxytocin induction was offered (n = 176, 19. 5%). The maternal and neonatal complications and outcomes of all pregnancies were reviewed and compared. Results Among the 903 cases, the total number of women without any medical interventions was 681, among which 505 (74.2%) fell into spontaneous labor, including 430 (63.2%) within 12 h with a cesarean section rate(CSR) of 20.7%(89/430), 75 (11.0%) at 12-24 h after PROM with the CSR of 50.7% (38/75), and 176 (25.8%) did not go into labor spontaneously (group 6) with a CSR of 70. 5% (124/176). (2) Among the 930 women, 398were induced at 6, 12 and 24 h after PROM. The CSR, incidence of intrauterine infection, puerperal morbidity and perinatal mortality rate in group 5 were significantly lower than those of group 6 [CSR:52.0%(51/98) vs 70. 5%(124/176); intrauterine infection: 6. 1%(6/98) vs 22. 7%(40/176);puerperal morbidity: 6. 1% (6/98) vs 19.9% (35/176); perinatal mortality: 7. 1% (7/98) vs 20.5%(36/176),all P＜0. 01], but no difference was found in the incidence of postpartum hemorrhage [1.0%(1/98) vs 4.0%(7/176), P＞0.05]. Conclusions Intervention is not recommended within 12 h after PROM in full term or near term gravidas. However, induction of labor should be offered thereafter. However, the CSR and incidence of maternal and neonatal complications rise up if induction of labor postponed to 24 h after PROM.

Objective To perform a nationwide external quality assessment for detection of Chlamydia trachomatis, and to improve the performance of laboratories in the detection of Chlamydia trachomatis. Methods Totally, 419 quality control samples were sent to tested laboratories, including 76 samples in 2007, 168 samples in 2008 and 175 samples in 2009. The laboratories were required to test the samples and report test results, within stipulated time, to the reference laboratory in National Center for Sexually Transmitted Disease (STD) Control, Chinese Center for Disease Control and Prevention. The reported results were statistically analyzed by the National Center for STD Control, who finally fed back the statistical results to all of the participants. Results The percentage increased from 84.93% in 2007 to 92.14% in 2009 for laboratories showing an 80% or more consistency with the reference laboratory in the detection of Chlamydia trachomatis from quality control samples (qualified), from 47.95% in 2007 to 70% in 2009 for those showing a 100% consistency (excellent), and dereased from 5.48% in 2007 to 0.71% in 2009 for those showing a consistency of lower than 60% (unqualified). The centralabs of provincial CDC and volunteer laboratories exhibited a satisfactory performance for the detection of Chlamydia trachomatis, while the performance of a small number of national STD surveillance sites needed to be increase. Conclusion The external quality assessment reveals a continuous improvement in the capability of detecting Chlamydia trachomatis in STD laboratories at different levels in China.

A stable HMG-CoA reductase (HMGR) reaction in vitro was developed by a sensitive, selective and precise liquid chromatography–tandem mass spectrometry (LC–MS/MS) method. The optimized enzyme reac-tion condition contained 1.5μg of HMGR, 20 nM of NADPH with 50 min of reaction time. The method was validated by several intra-and inter-day assays. The production transitions of m/z 147.0/59.1 and m/z 154.0/59.1 were used to detect and quantify mevalonolactone (MVAL) and MVAL-D7, respectively. The accuracy and precision of the method were evaluated over the concentration range of 0.005–1.000μg/mL for MVAL and 0.010–0.500μg/mL for lovastatin acid in three validation batch runs. The lower limit of quantitation was found to be 0.005μg/mL for MVAL and 0.010μg/mL for lovastatin acid. Intra-day and inter-day precision ranged from 0.95%to 2.39%and 2.26%to 3.38%for MVAL, 1.46%to 3.89%and 0.57% to 5.10% for lovastatin acid, respectively. The results showed that the active ingredients in Xuezhikang capsules were 12.2 and 14.5 mg/g, respectively. This assay method could be successfully applied to the quality control study of Xuezhikang capsule for the first time.
