ABSTRACT
OBJECTIVE: To explore the method of management of asymptomatic bacterial vaginosis,and to evaluate the effect of probiotics on asymptomatic bacterial vaginosis and analyze the benefit gained by those patients.METHODS: A multicenter,randomized,double-blind,controlled study was performed with probiotics in test group,and placebo in control group,from september 2013 to september 2016 in 4 hospitals.Forty five patients in test group were treated with vaginal capsule probiotics,and placebo was used in forty-five patients in control group.The follow-up in both groups lasted for 4 weeks.Cure rate,relapse rate and progression rate in both groups were analyzed to evaluate the effect and the benefits gained by patients.RESULTS: Ninty patients were recruited in the study,and seventy-nine patients finished the study and were followed up with complete information.Two weeks after the treatment,in FAS the cure rate in test group was significantly higher than that of the control(44.4% vs. 6.7%,P0.05).In PPS,the cure rate in test group was significantly higher than that of the control(52.5% vs. 2.6%,P0.05).After 2 weeks of treatment,there was no relapsed patient.Four weeks after the treatment,in FAS the cure rate in test group was significantly higher than that of the control(46.7% vs. 8.9%,P0.05).In PPS,the cure rate in test group was significantly higher than that of the control(57.5% vs. 5.1%,P0.05).Four weeks after the treatment,there was no relapsed patient,either.CONCLUSION: Vaginal capsule probiotics can be used to treat asymptomatic BV with high cure rate,less side effect and low relapse rate.
ABSTRACT
The regio- and stereo-selective hydroxylations of two ingenane diterpenoids, 20-deoxyingenol (1) and 13-oxyingenol dodecanoat (2), by the filamentous fungi Mortierella ramanniana and Gibberella fujikuroi were investigated in the present study. Four undescribed metabolites (3-6) of substrate 1 and two undescribed metabolites (7 and 8) of substrate 2 were isolated. All the metabolites were identified as hydroxylated ingenane derivatives by extensive NMR and HR-ESI-MS data analyses. All the biotransformed compounds and the substrates were evaluated for their cytotoxicities against three human cancer cell lines, including human colon cancer Caco-2, breast cancer MCF-7, and adriamycin (ADM)-resistant MCF-7/ADM cell lines. All ingenane alcohols (1, and 3-6) displayed no significant cytotoxic activities. The substrate 13-oxyingenol dodecanoat (2) showed moderate cytotoxicity with IC values being 35.59 ± 5.37 μmol·L (Caco-2), 24.04 ± 4.70 μmol·L (MCF-7), and 22.24 ± 5.19 μmol·L (MCF-7/ADM). However, metabolites 7 and 8 displayed no significant cytotoxicity. These results indicated that the hydroxylation at the C-13 aliphatic acid ester of substrate 2 can significantly reduce the cytotoxic activity.

<p><b>OBJECTIVE</b>To investigate the factors related to clinical pregnancy outcomes of in vitro fertilization-embryo transfer (IVF-ET) in women with secondary infertility.</p><p><b>METHODS</b>The clinical, laboratory and follow-up data of 1129 cycles in 1099 patients with secondary infertility undergoing IVF-ET in Women's Hospital, Zhejiang University School of Medicine between July 2012 to July 2014 were retrospectively reviewed. The factors related to pregnancy outcomes were analyzed by univariate and logistic regression methods. The clinical pregnancy rates in women with different age and different number of embryos transferred were compared. The clinical outcomes of stimulation with gonadotropin releasing hormone (GnRH) agonist long protocol, GnRH agonist short protocol and GnH antagonist protocol were evaluated in secondary infertile patients aged ≥ 40 years.</p><p><b>RESULTS</b>Among 1129 cycles, 376 cases (33.30%) had clinical pregnancy and 753 cases (66.70%) had no clinical pregnancy. There were significant differences in age, body mass index, basal follicle-stimulating hormone level, antral follicle number,paternal age and number of embryos transferred between pregnancy and no pregnancy groups (P<0.05); while only maternal age (OR=0.900, 95% CI: 0.873~0.928, P<0.001) and the number of embryos transferred (OR=2.248, 95% CI: 1.906~2.652, P<0.001) were the independent factors affecting the clinical pregnancy outcome of IVF-ET. There was no significant difference in clinical pregnancy rate between women aged 30~40 years with two embryos transferred and those aged<30 years with two or three embryos transferred(P>0.05). There were no significances in clinical pregnancy rate among women aged ≥ 40 years using GnRH agonist long protocol,GnRH agonist short protocol and GnRH antagonist protocol for stimulation (P>0.05).</p><p><b>CONCLUSION</b>Maternal age and number of embryos transferred have independent effect on IVF-ET clinical pregnancy outcome of secondary infertile women. We suggest that no more than two embryos should be transferred for women in their thirties to minimize the risk of multiple pregnancy while still having an acceptable pregnancy rate. The pregnancy rate of patients over 40 years decreases significantly, and there is no difference in pregnancy rate by using GnRH agonist long protocol, GnRH agonist short protocol or GnRH antagonist protocol.</p>
