芳香烃受体及其核转位蛋白与复发性流产的关系

摘要

目的 探讨不同部位芳香烃受体(AhR)、核转位蛋白(ARNT)、雌二醇(E2)、雌激素受体(ER)表达水平与复发性流产(RSA)的关系.方法 选择2016年5月至2017年9月在山西大医院妇产科门诊行早期人工流产的RSA患者64例(RSA组),既往有正常胎儿分娩史、自愿行人工流产的正常早孕妇女30例(正常组).在人工流产的同时留取绒毛、蜕膜组织及其外周血,用酶联免疫法检测两组患者绒毛、蜕膜组织中AhR、ARNT、ER及外周血中AhR、ARNT水平,用微粒子化学发光免疫法检测两组外周血中E2水平,对有关数据进行统计分析.结果 (1)RSA组外周血中ARNT水平显著高于正常组,差异有统计学意义(P＜0.05);两组外周血中AhR、E2水平组间比较差异无统计学意义(P＞0.05).RSA组绒毛及蜕膜组织中AhR、ARNT水平显著高于正常组(P＜0.05);而ER水平低于正常组,差异有统计学意义(P＜0.05).(2)两组绒毛组织、蜕膜组织中的AhR/ARNT比值差异均无统计学意义(P＞0.05);RSA组绒毛组织和蜕膜组织中的AhR/ER、ARNT/ER比值均高于正常组,差异有统计学意义(P＜0.05).结论 绒毛、蜕膜组织中AhR、ARNT过度表达,ER低表达可能与RSA的发生有关.%Objective To explore the relationship between aryl hydrocar-bon receptor (AhR),aryl hydrocarbon receptor nuclear translocator (ARNT),estradiol (E2),estrogen receptor (ER) and recurrent spontaneous abortion (RSA) through observing the level of serum AhR,ARNT,E2,and AhR,ARNT,ER in decidua and chorionic tissues of the patients with recurrent spontaneous abortion.Methods 64 cases of RSA patients who induced abortion at the Shanxi Dayi hospital from May 2015 to September2017 were chosen as RSA group,and 30 cases of healthy abortion women of the same period who had born full-term normal fetus were choosen as the normal group.The serum,villi and decidua of each case were collected during abortion.The level of AhR,ARNT,ER of both groupswere detected by enzyme-linked immunoscrbent assay (ELISA) method.The Serum E2 lever were detected by the method of chemical luminescence.The data of all the patients were analyzed.Results (1) The level of ARNT in peripheral blood of RSA group was significantly higher than that of normal group (P ＜ 0.05),and the levels of AhR and E2 in peripheral blood were not statistically significant between the two groups (P ＞ 0.05).The levels of AhR and ARNT in villi and decidua were significantly higher in RSA group than in normal group (P ＜ 0.05),while the expression of ER in villi and decidua was significantly lower in RSA group than in normal group (P ＜ 0.05).(2) There was no significant difference in the ratio of AhR/ARNT between the two groups (P ＞ 0.05);the ratio of AhR/ER and ARNT/ER in the villi and decidua of the RSA group was higher than that of the normal group (P ＜ 0.05).Conclusions Overexpression of AhR and ARNT and low expression of ER in villi and decidua tissues may be related to the occurrence of RSA.
