摘要: 目的:探讨新生儿缺氧缺血性脑病与血管紧张素转换酶(ACE)基因多态性的关系,寻找其易感基因,以便在围生期进行早期干预,减少该病的发生率。 方法:应用PCR-RFLP方法对新生儿缺氧缺血性脑病患儿51例(观察组)和正常新生儿53例(对照组)的ACE基因多态性进行分析。 结果:ACE基因分为DD、ID和Ⅱ 3种类型。观察组与对照组ACE基因型分布频率不同,前者以D等位基因为主(56.9%),后者以I等位基因为主(66.0%),两组比较差异有显著性(P<0.005)。 结论:新生儿缺氧缺血性脑病与ACE基因多态性有关联, D等位基因可能为本病的易感基因。

Abstract: Objective To explore the relationship between hypoxic-ischemic encephalopathy (HIE) of newborn and the polymorphism of angiotensin converting enzyme (ACE) gene to find the susceptible gene of HIE by analyzing the polymorphism of the ACE gene in order to intervene early in the perinatal stage and reduce the incidence of HIE of newborn. Methods The polymorphism of ACE genes of 51 newborns with HIE and 53 normal newborns were analyzed with PCR-RFLP. Results There were three kinds of genotypes of ACE gene :DD,ID and II. In the observation group, the distribution frequency of the D allele (56.9%) was higher than that in the control group (34.0%), the difference was statistical significant (P<0.005). Conclusion The significant association between the ACE genotype and HIE of newborn is found, D allele gene may be the susceptible gene of HIE.
