Abstract
目的 探讨孕妇血清可溶性B7-H4(soluble B7-H4,sB7-H4)浓度和未足月胎膜早破(preterm premature rupture of membranes,pPROM)之间的关系.方法 研究纳入41例患者,其中未足月胎膜早破组患者22例、足月胎膜早破(pre-mature rupture of membranes,PROM)组患者19例:同时纳入35例健康妊娠女性为时照组;采用酶联免疫吸附测定受试者妊娠11~13周时血清中sB7-H4的浓度.结果 pPROM组患者血清中sB7-H4的浓度高于PROM组患者和对照组女性,其差异均有统计学意义(P<0.05):区分pPROM组患者与对照组患者的sB7-H4临界值为13.01 ng/ml,特异度为96.5%,敏感度为62.1%.结论 pPROM组患者妊娠早期血清中sB7-H4的浓度既可预示母胎交互作用时的动态免疫反应程度,也可作为妊娠并发症的预测指标.
