Objective To explore the role of estradiol decline in the early luteal phase (the 2nd day after oocyte retrieval) in the prediction of in-vitro fertilization outcomes. Methods A total of 236 cases under in vitro fertilization-embryo transfer (IVF-ET)/ intracytoplasmic sperm injection-embryo transfer(ICSI-ET) cycles were included in this retrospective study of their medical records. The cases were divided into three groups according to the levels of estradiol decline on the 2nd day following OPU: group A (n = 70) with the decline rate of less than 70%, group B (n=114) with the decline rate of 70%~80%and group C (n=52) at the decline rate of more than 80%. The comparisons were done among the three groups in terms of the number of oocyte retrieval, the rate of fertilization, the rate of best oocytes and the rate of miscarriage. Results There were no significant differences statistically in the number of oocyte retrieval, the rate of fertilization, the rate of best oocytes and the rate of miscarriage (P > 0.05). But the rates of clinical pregnancy rate in groups A and B were significantly higher than that in group C (68.6% and 68.4% vs. 44.2%) (P < 0.05). Conclusion The levels of estradiol declines in the early luteal phase may be important in the prediction of IVF outcomes.

Objective To investigate the effect of HO-1 on acute rejection after orthotopic liver transplantation (OLT) in rats. Methods Taking dark agouti (DA) rats as donors and Lewis rats as recipients, OLT was performed. Before OLT, the DA rats and Lewis rats were matched in pairs, and divided into control group, ZnPP group and CoPP group, the paired rats of which intraperitoneally received normal saline, 20 mg/kg ZnPP and 5 mg/kg CoPP respectively 24 h before OLT. Ten pairs of rats were in each group. On day 3 or 7 after OLT, recipient rats were killed, then blood sample and liver specimen were collected. Plasm levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TBIL), albumin (ALB) were measured; HE staining and MPO staining were performed; The expression of HO-1 was detected by the fluorence real time RT-PCR. Results On day 3 and 7 after OLT, AST, ALT and TBIL showed significant statistical significance among the three groups; ALB was highest in CoPP group, then in control group, lowest in ZnPP group. On day 3 after OLT, control group had acute rejection of degree one to degree two, ZnPP group had acute rejection of degree two; CoPP group mainly had acute rejection of degree one; On day 7 after OLT, control group mainly had acute rejection of degree two; ZnPP group had acute rejection of degree two to degree three; CoPP group had acute rejection of degree one to two. The expression of HO-1 was highest in CoPP group, then control group, and lowest in ZnPP group. Conclusion The expression of HO-1 in OLT with acute rejection in rats can palliate the acute rejection.
