Abstract:

目的探讨白细胞介素1受体拮抗剂(Interleukin-1ReceptorAntagonist,IL-1Ra)基因多态性与宁夏汉族复发性自然流产(RecurrentSpontaneousAbortion,RSA)的相关性。方法应用聚合酶链反应(PolymeraseChainReaction,PCR)技术检测191例反复自然流产患者和193例健康对照IL-1RN第二内含子中可变串联重复序列(VariableNumberofTandemRepeats,VNTR)多态性。结果RSA组和对照组IL-1RN*1/1、IL-1RN*1/2、IL-1RN*1/3、IL-1RN*1/4、IL-1RN*2/2基因型频率分别为75.39%、20.42%、0、1.05%、3?14%和83.94%、11.92%、1.04%、2.07%、1.04%;等位基因IL-1RN*1、IL-1RN*2的频率分别为86?13%、13.35%和91.45%、6.99%,两组间差异有统计学意义(?P?<0.05)。携带有IL-1RN*2等位基因的个体发生复发性自然流产的危险性显著高于携带IL-1RN*1的个体(?OR=2.03?,95%?CI?1.242~3.308)。结论IL-1RN*2可能与宁夏汉族复发性自然流产的遗传易感性有关。
