摘  要:目的探讨血管紧张素I转换酶(ACE)基因I/D多态性在特发性肺纤维化(IPF)发病中的作用。方法应用PCR技术检测42例IPF患者(IFP组)和90例健康查体者(对照组)ACE基因I/D多态性,并分析不同基因型和等位基因者IPF发病危险性。结果IPF组DD基因型和D等位基因频率均显著高于对照组(P〈0.05);与Ⅱ基因型比较,携带DD型和D等位基因个体发生IPF的风险分别增加2.97倍(95%CI为1.13—7.73)和1.96倍(95%CI为1.16—3.32),P均〈0.05。结论ACE基因I/D多态性与IPF发病有关,DD基因型和D等位基因可能增加IPF的患病风险。Objective To investigate the effect of angiotensin converting enzyme(ACE) gene insertion/deletion(I/D) polymorphism in the pathogenesis of the idiopathic pulmonary fibrosis(IPF). Methods The ACE gene I/D polymorphism was determined by PCR in 42 IPF patients ( IPF group) and 90 normal controls( control group). Occurrence risk of the individuals with different genetype and allele were analyzed. Results The frequencies of DD genetype and D allele in the IPF group were both higher than those in the control group (P 〈0.05). As compared with II genotype,the individuals with DD genotype and D allele were 2.97 (95 % CI: 1.13 -7.83 ) and 1.96 (95 % CI: 1.16 -3.32 ) times susceptible to IPF, both P 〈 0.05. Conclusions ACE gene I/D polymorphism is associated with the pathogenasis of IPF. The DD genotype and D allele may increase the risk of IPF.
