【摘要】 目的 探討E26轉(zhuǎn)錄因子��1(E26 transformation specific��1, Ets��1)蛋白在胎膜早破中的表達(dá)和意義。方法 采用免疫組織化學(xué)S�睵法在蛋白水平檢測(cè)75例胎膜早破者(病例組)及70例無(wú)其他產(chǎn)科并發(fā)癥及內(nèi)外科合并癥的足月?lián)衿谄蕦m產(chǎn)者(對(duì)照組)胎膜中Ets��1蛋白的表達(dá)。結(jié)果 ①Ets��1蛋白在胎膜滋養(yǎng)層細(xì)胞核及胞漿中均有表達(dá)，以胞核表達(dá)為主;②Ets��1蛋白在胎膜早破組滋養(yǎng)層中高表達(dá)，與對(duì)照組比較，有顯著性差異(P<0.05);③Ets��1蛋白在未足月胎膜早破組滋養(yǎng)層中高表達(dá)，但與足月胎膜早破組比較，無(wú)顯著性差異(P>0.05)。結(jié)論 轉(zhuǎn)錄調(diào)節(jié)因子Ets��1在人類胎膜上有表達(dá)，且在胎膜早破中高表達(dá)，表明Ets��1蛋白可能使胎膜細(xì)胞外基質(zhì)重塑從而引發(fā)胎膜早破。本研究可作為預(yù)測(cè)胎膜早破發(fā)生的依據(jù)。

ABSTRACT: Objective To examine the expression and clinical significance of E26 transformation specific��1 in premature rupture of fetal membranes. Methods Fetal membranes from 75 women in the following categories were analyzed for Ets��1 expression: preterm and term premature rupture of fetal membranes; 70 women (control group) with term cesarean sections and without complications. Ets��1 protein was localized with the use of immunohistochemical S�睵 method. Results Ets��1 protein was expressed in both the nucleus and cytoplasm of trophoblast of human fetal membranes, with more obvious expression in the nucleus. Ets��1 protein�餾 expression was up�瞨egulated in the trophoblast of fetal membranes with premature rupture, which differed significantly from the control group (P<0.05). Ets��1 protein's expression was up�瞨egulated in the trophoblast of fetal membranes with preterm premature rupture, which did not differ significantly from the control group (P>0.05). Conclusion Ets��1 is expressed in human fetal membranes and its expression is up�瞨egulated with premature rupture of fetal membranes, suggesting a role for Ets��1 in extracellular matrix remodeling of the membranes. This study provides an evidence to predict premature rupture of fetal membrances醫(yī).學(xué)全.在.線網(wǎng)站gydjdsj.org.cn.

胎膜早破(premature rupture of fetal membranes, PROM)是臨產(chǎn)前胎膜發(fā)生破裂，分為未足月胎膜早破(preterm premature rupture of fetal membranes, PPROM)和足月胎膜早破(term premature rupture of membranes, TPROM)，其發(fā)生率國(guó)內(nèi)報(bào)道為2.7%～17%，國(guó)外報(bào)道為5%～15%[1]。且發(fā)病率正逐年升高，其中約30%～40%胎膜早破并發(fā)早產(chǎn)，為新生兒發(fā)病率和病死率上升的一個(gè)重要原因。
