摘要: 目的:探讨血管紧张素Ⅱ 1型受体(AT1R) 基因非编码区(-535)位点多态性与妊娠期高血压疾病(HDCP)发病的关系。方法:采用聚合酶链反应-限制性酶切片段长度多态性(PCR-RFLP)技术检测86例HDCP组孕妇(妊娠期高血压17例、子痫前期轻度28例、子痫前期重度23例、子痫18例)和74例对照组(正常孕妇)基因型。结果:①HDCP组孕妇AT1R 基因(-535)位点基因型CC、CT、TT频率分别为74.4%、20.9%和4.7%,对照组分别为87.8%、8.1%和4.1%,两组基因型频数分布比较差异无显著性(P>0.05);HDCP组孕妇AT1R 基因(-535)位点等位基因C、T频率分别为84.9%和15.1%,对照组分别为91.9%和8.1%,两组等位基因频率比较差异亦无显著性(P>0.05);②HDCP组妊娠期高血压、子痫前期轻度、子痫前期重度和子痫孕妇(-535)位点T等位基因频率分别为5.9%、7.1%、15.2%和36.1%,前3者与子痫患者比较差异均有显著性(P<0.05)。结论:AT1R基因(—535)C→T变异与妊娠期高血压疾病发病无关,但与病情严重程度有关

Abstract: Objective To investigate the association between angiotensin Ⅱ type 1 receptor (AT1R) gene polymorphism and hypertensive disorder complicating pregnancy (HDCP). Methods Eighty-six pregnant women with HDCP and 74 normal pregnant women (control group) were recruited. Gene polymorphism of AT1R at (-535)was detected with PCR-based restriction fragment length polymorphism(RFLP)method. Results ① The frequencies of CC,CT,TT genotypes of AT1R at (-535) were 74.4%,20.9%,4.7% in HDCP group and 87.8%,8.1%,4.1% in control group,respectively;there was no significant difference berween two group(P>0.05).The frequencies of the two alleles C, T were 84.9%,15.1% in HDCP group and 91.9%,8.1%in control group,respectively;there was no significant difference between two group (P>0.05);②The distribution frequencies of AT1R at(-535) in HDCP group in gestational hypertension,mild preeclampsia,severe preeclampsia(5.9%,7.1%,15.2%)were lower than that in eclampsia in HDCP group(P<0.05).Conclusion The AT1R (-535) C→T gene polymorphism is not associated with the pathogenesis of HDCP, but it has an association with the severity of HDCP.
