ABSTRACT
Objective To explore the application value of hysteroscopy in recurrent implantation failure ,and discuss what was the best time to transfer embryos after the operation .Methods The patients who had undergone two or more failed IVF-ET cycles were separated into two groups .The patients of group A ( n=210) received hysteroscopy , and the patients of group B ( n=71) did not receive hysteroscopy evaluation .Intrauterine lesions diagnosis were trea-ted during the procedure .Patients without intrauterine pathologies were given slight curettage .The recurrent IVF-ET were performed after the procedure .Then we analyzed the clinical pregnancy rate of the two groups and determined the best time to transfer embryos after the operation.Results In group A,57 patients were pregnant.In group B, 8 patients were pregnant .There was a significant difference in the clinical pregnancy rates between the two groups (χ2 =7.52,P<0.01).In the pregnant patients of group A ,about 94.7%were pregnant in 6 months after hysterosco-py.Conclusion The patients with recurrent IVF -ET transfer failure should be evaluated prior to commencing IVF-ET cycle to improve the clinical pregnancy rate .It is better to transfer embryos within 6 months after hysteroscopy operation.
ABSTRACT
Objective To study the effect of intedeukin 6 (IL-6) on the expression of androgen receptor (AR) in porcine ovarian granulosa cells(GC) and to explore its role of in the polycystic ovary syndrome(PCOS) pathogenesis.Methods Different concentrations of IL-6 (10,100 and 1 000 ng/L) were treated with GC.Expression of androgen receptor (AR) mRNA and protein in GC were detected by real-time quantitative RT-PCR and Western blot.Results The mRNA and protein expressions of AR in GC were upregulated in groups with 100 and 1 000 ng/L IL-6 at 72 h.Conclusion IL-6 can improve androgen activity.This process may explain the function of chronic subclinical inflammation in PCOS pathogenesis.
ABSTRACT
Objective:To study the immunologic and endocrinologic mechanism of Chinese herbs in the treatment of abortion Methods:SD rats injected with bromocriptine 0 125 mg/d subcutaneously(sc)during day 6~8 of pregnancy were used as aborting model Uteruses of the rats treated with or without Chinese herbs were taken out at day 12 of pregnancy for counting embryoes and determining mRNA levels of Th1/Th2 type cytokines in decidua by semiquantity RT PCR Results:The insufficiency of PRL and P in serum during gestation was related to embryo miscarriage remarkably A predominant Th1 response at the maternal fetal interface is harmful to pregnancy Aborting rate induced by bromocriptine was decreased after treating with Chinese herbs Chinese herbs can increase serum PRL and P , then trigger a predominant Th2 response in the model Conclusion:With it's effect of increasing PRL and P in serum and the Th2 bias response at the maternal fetal interface, Chinese herbs can reverse the abortion effect of bromocriptine
