Objective To investigate the influence of high body mass index (BMI) on in vitro fertilization and embryo transfer (IVF-ET) pregnancy outcome in the patients with polycystic ovary syndrome (PCOS) .Methods A retrospective cohort study was conducted using existing data on 224 PCOS patients with IVF-ET by the standard long protocol in this hospital from Jan 2009 to Dec 2011 .All patients were divided into 2 groups according to BMI ,the high BMI group(BMI≥24 .0 ,64 cases) and the normal BMI group(18 .5≤BMI<24 .0 ,160 cases) .The differences of pregnaney outcomes between the high BMI and normal BMI PCOS pa-tients were compared .Results 1 .Basic testosterone(T) in the high BMI group was higher than that in the normal BMI group(P<0 .05) .2 .There were no statistical difference in the number of retrived oocytes ,dose of Gn ,Gn duration ,fertilization rate between the two groups(P>0 .05);the high BMI group demonstrated the higher endometrial thickness and lower good quality embryo rate than the normal BMI group(P<0 .05) .3 .There were no statistical difference in the clinical pregnancy rate and the abortion rate be-tween the two groups(P>0 .05) ,the high BMI group had the higher risk of developing gestational diabetes(GDM)than the normal BMI group(P<0 .05) .Conclusion PCOS patient with high BMI is liable to develop hyperandrogenism and increases the occurrence rate of pregnancy complication gestational diabetes mellitus (GDM ) ,but without affecting the clinical pregnancy rate .

Objective To investigate application of femoston combined with Kuntai capsule in poor ovarian responders (PORs) receiving vitro fertilization. Methods 120 women with poor ovarian response after receiving IVF were s randomly elected. Pre-treatment with femoston plus Kuntai capsule was used for three menstrual cycles before the next cycle of assisted reproductive treatment. FSH, LH, E2, AMH, number of antral follicles, PSV, days of Gn, ampoules of Gn, cycle cancellation rate, E2 value of the day of HCG, follicle of less than 16mm, number of oocytes, fertilization rate, and number of good quality embryos were compared before and after treatment used. Results After pre-treatment, levels of FSH and LH were decreased, AMH, PSV were increased, E2 value of the day of HCG, number of antral follicles, follicle of less than 16 mm, oocytes, fertilization rate, and good quality embryos were increased; cycle cancellation rate was decreased, with significant differences (P< 0.05). Conclusions Femoston combined with kuntai capsule can effectively increase the functional reserve of the ovarian in poor ovarian responders, and can improve the outcome of IVF.

Objective To compare the clinical outcomes of two D3 embryo and single blastocyst transfer in patients retrieving different oocytes, so as to provide data support for selecting a clinical transfer strategy. Methods We made a retrospective analysis of patients who underwent in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI)between January and December 2014 in the Reproductive Medicine Center,the Third Affiliated Hospital of Zhengzhou University.The patients were divided into three groups according to the number of oocytes received:Group A (5-9 oocytes),Group B (10 - 14 oocytes)and Group C (≥ 1 5 oocytes).Patients in each group all received four different transfer methods as follows:transfer of two fresh D3 embryos (a ),transfer of one fresh blastocyst (b ),transfer of two D3 frozen embryos (c ),and transfer of one frozen blastocyst (d ).We compared the 2PN fertilization rate of oocytes,rate of available embryos and rate of good embryos among the three groups.We also compared the embryo implantation rate,biochemical pregnancy rate,clinical pregnancy rate, multiplets rate and abortion rate among the four transfer methods in each group.Results ① There were 667, 573,and 479 transfer cycles in Group A,Group B and Group C,respectively.The 2PN fertilization rate of IVF and available embryos rate was significantly higher in Group A than in Group B and Group C (P =0.003/P <0.001).② There was no significant difference in biochemical pregnancy rate,clinical pregnancy rate or abortion rate with the four transfer methods in Group A (P >0.05),but the implantation rate of c was significantly lower than that of a and d (P =0.027/0.020),d had a higher implantation rate than a and c in Group B (P =0.005/0.001).In Group C,the biochemical pregnancy rate and clinical pregnancy rate of d were significantly higher than those of a (P =0.048/0.027)and c (P =0.003/0.001).Patients in Group C also had a higher implantation rate than D3 embryos (P <0.05).③ The multiple pregnancy rate of single blastocyst transfer decreased compared with D3 embryos transfer in the three groups (P <0.05).Conclusion Single blastocyst transfer has both higher implantation rate and lower multiple pregnancy rate in high response patients (1 5 or more oocytes received).For patients who received 5-9 and 10-14 oocytes,D3 embryos have a similar clinical pregnancy rate with that of single blastocyst but a higher multiple pregnancy rate.Single vitrified-warmed blastocyst transfer has a higher clinical pregnancy rate.It is the best transfer method for patients who received more than 10 oocytes.

Objective:To explore the effectiveness, safety and cost between urinary follicle stimulating hormone (uFSH) and recombinant follicle stimulating hormone (rFSH) in controlled ovarian stimulation (COS) in China.Methods:Data were collected from 16 reproductive centers in China covering oocytes collection time from May 1, 2015 to June 30, 2018. Eligible patients were over 18 years old, adopting COS with uFSH (uFSH group) or rFSH (rFSH group) as start gonadotropins (Gn), and using in vitro fertilization (IVF) and (or) intracytoplasmic sperm injection for fertilisation, excluding frozen embryo recovery cycle. Generalised estimating equation was used to address the violation of independency assumption between cycles due to multiple IVF cycles for one person and clustering nature of cycles carried out within one center. Controlling variables included age, body mass index, anti-Müllerian hormone level, cause of infertility, ovulation protocol, type of fertilisation, number of embryos transferred, number of days of Gn use.Results:Totally 102 061 cycles met eligibility criteria and were included in the analyses. In terms of effectiveness, after controlling relevant unbalanced baseline characteristics, compared with rFSH group, the high oocyte retrieval (>15 oocytes was considered high retrieval) rate of uFSH group significantly decreased in gonadotropin-releasing hormone agonist protocol ( OR=0.642, P<0.01) and in gonadotropin-releasing hormone antagonist protocol ( OR=0.556, P=0.001), but the clinical pregnancy rate per transfer cycle and the live birth rate per transfer cycle significantly increased ( OR=1.179, OR=1.169, both P<0.01) in both agonist and antagonist protocols. For safety, multiple analysis result demonstrated that in the agonist protocol, compared with rFSH group, the incidence of moderate to severe ovarian hyperstimulation syndrome of uFSH group significantly decreased ( OR=0.644, P=0.002). The differences in ectopic pregnancy rate and multiple pregnancy rate between the uFSH and rFSH groups were not significant ( P=0.890, P=0.470) in all patients. In terms of cost, compared with rFSH group, the uFSH group had lower total Gn costs for each patient ( P<0.01). Conclusion:For patients who underwent COS, uFSH has better safety, and economic profiles over rFSH in China.

To detect the concentration of triptolide in skin and joint after percutaneous administration,an HPLC-MS/MS method and skin and joint micro-dialysis( MD) method of triptolide were established in this study. The separation was achieved on triple quadrupole( AB QTRAP4500) and phenomenex-C18( 4. 6 mm×150 mm,5 μm,luna) column with acetonitrile-water with 0. 1% formic acid( 65 ∶35) as the mobile phase at a flow rate of 0. 7 m L·min-1. An electrospray ionization( ESI) source was applied and operated in the positive multiple reaction monitoring( MRM) mode. The fragment ion for triptolide was m/z 361. 1→145. 0. The effects of different perfusion [Ringer's,PBS( p H 7. 4),30% ethanol saline]drug concentrations and flow rates on the recovery rate,as well as the relationship between the recovery rate and the loss rate were determined by incremental( dialysis) and reduction( retrodialysis) methods.The reduction method was applied in the in vivo study to investigate and determine the stability of the probe recovery rate in 10 h. The results of HPLC-MS/MS detection method conformed to the requirements of biological samples. The perfusion fluid was 30% ethanol saline. The recovery rate of skin and joint probes in vitro of triptolide increased within the flow rate of 0. 5-2. 5 μL·min-1. In order to increase the timeliness of data and the accuracy,the flow rate was determined to be 1 μL·min-1,and the sample interval was determined to be 0. 5 h. The recovery rate of triptolide in skin and joint probes in vitro and the loss rate were stable and equal despite of change of triptolide concentration within 10-200 μg·L-1. This indicated that the effect of drug concentration on the MD probe recovery rate was small,and the recovery rate could be replaced by the loss rate. The loss rate in vivo using MD method was measured at 10 h,indicating that the transfer rate of triptolide was stable within 10 h. The established method of triptolide in MD and HPLC-MS/MS can be applied to investigate the kinetic in skin and joint after percutaneous administration of triptolide.
