【摘要】：目的探讨晚卵泡期高孕酮(P)对卵巢正常反应者种植窗期内膜胞饮突、整合素、白血病抑制因子(LIF)及白介素-1(IL-1)表达的影响。方法选取2014年4月至2015年12月在郑州大学第二附属医院行长方案体外受精-胚胎移植(IVF-ET)助孕的29例卵巢正常反应患者,在本次取卵周期取消移植。按照h CG日孕酮水平分为:高P组(≥7.13nmol/L)18例,P未升高组(7.13nmol/L)11例。取卵后5 d采集内膜组织,扫描电镜观察内膜胞饮突变化,Western blot法检测两组子宫内膜整合素、LIF、IL-1蛋白表达变化。结果内膜胞饮突在高P组出现皱缩,P未升高组呈发育中及完全发育状态;高P组内膜整合素(0.227±0.060 vs.0.512±0.031)、LIF(0.144±0.018 vs.0.474±0.041)、IL-1(0.220±0.009 vs.0.460±0.035)蛋白表达量均低于P未升高组(P0.05)。结论 h CG日高孕酮改变了卵巢正常反应人群种植窗期内膜胞饮突、整合素、LIF及IL-1的表达,可能使种植窗期子宫内膜的发育提早成熟,导致胚胎-子宫内膜对话失败。
[Abstract]:Objective to investigate the effects of high progesterone (P) in late follicular phase on the expression of integrin, leukaemia inhibitor (LIF) and interleukin-1 (IL-1) in cultured endometrium of normal ovarian responders. Methods from April 2014 to December 2015, 29 normal ovarian response patients who were assisted by in vitro fertilization and embryo transfer (IVF-ET) in the president's program of the second affiliated Hospital of Zhengzhou University were selected. According to the level of progesterone on h CG day, 18 cases were in high P group (鈮，
