Recent studies have suggested that the hydrosalpinx has a negative effect on pregnancy outcome, with markedly diminished implantation and increased early pregnancy loss. Fluid from the hydrosalpinx may leak into and accumulate in the uterine cavity. It is not clear, however if this creates a hostile local environment in the uterus for embryo implantation or exerts a direct embryotoxic effect. This study was conducted to investigate the detrimental effects of hydrosalpinx fluid (HSF) on the development of mouse embryos in vitro and to demonstrate whether Vero cells overcome these adverse effects. HSF was collected from three women with bilateral hydrosalpinx at the time of laparoscopic surgery. Collected fluid was centrifuged and the supernatant was frozen at -20degrees C. For co-culture, Vero cells were commercially obtained in a frozen state and cultured using Ham's F10 medium. Single-cell mouse embryos (B6CBAF1) were cultured for 5 days in 0, 0.4, 0.8, and 1.2% of HSF in media with and without Vero cells and examined daily to record the number of embryos reaching expanded blastocyst and hatching stage. Co-culture of mouse embryos with Vero cells at 0.8% HSF concentration significantly enhanced embryo development, but not at 1.2% hydrosalpinx fluid concentration. These results suggest that HSF is highly embryotoxic and Vero cells are likely to overcome these detrimental effects to some degree.

To explore the roles of tumor necrosis factor-alpha (TNF-alpha) and heat shock protein 60 (HSP-60) in women with tubal factor infertility (TFI) associated with Chlamydia trachomatis, and to determine the mechanisms of fallopian adhesions in Chlamydia trachomatis (CT) infections, the expressions of TNF-alpha and HSP-60 were quantitatively determined in 60 cases of TFI and 30 controls by immunohistochemical technique. The patients with TFI were further divided into group A and group B according to the CT-DNA of cervical specimens of PCR. The quantitative analysis was conducted by employing computerized image analysis system. It is found that the expressions of TNF-alpha and HSP-60 were much higher in TFI patients than those of controls. Among CT-HSP responders, a stronger expression was correlated with more severe salpingeal pathology. It is concluded that TNF-alpha and HSP-60 play very important roles in fallopian tube adhesion and occlusion in TFI due to CT infection.

OBJECTIVETo study the effect and mechanism of Bushen Tiaojing Recipe on improving oocyte and embryo qualities in patients undergoing in vitro fertilization-embryo transfer (IVF-ET) at the super-ovulatory cycle.

METHODSFifty-eight tubal infertility patients undergoing IVF-ET were randomly assigned to two groups. Thirty patients in the treatment group were treated with Bushen Tiaojing Recipe and GnRHa/FSH/hCG, and twenty-eight patients in the control group were treated with GnRHa/FSH/hCG. Contents of GDF-9 in the mature follicular fluid were detected by Western blot. The expressions of GDF-9 in granulose cells were detected by Real-time PCR. The dose of gonadotropin (Gn), the number of oocytes obtained, the fertilization rate, the oocyte cleavage rate, the high quality embryo rate, and the pregnancy rate were compared.

RESULTSThe contents of GDF-9 in the follicular fluid and its expression in granulosa cells were significantly higher in the treatment group than in the control group (P<0.05). The number of oocytes obtained, the fertilization rate, the high quality embryo rate, and the pregnancy rate were significantly higher in the treatment group than in the control group. There was no significant difference in the dose of Gn or the oocyte cleavage rate.

CONCLUSIONSBushen Tiaojing Recipe could improve the pregnancy rate of IVF-ET. Its mechanism might be possibly through regulating the GDF-9 contents in the follicular fluid and granulosa cells.
