摘要
目的:探讨补体C3基因多态性与中国华东地区汉族人群缺血性脑卒中(ischemic stroke,IS)易感性之间的关系。方法:收集IS病例组及对照组各700例,采用TaqMan荧光探针法对所有研究对象进行rs2277984 G/A、rs3745565G/C位点基因型检测,多因素Logistic回归方法校正传统危险因素后分析各位点多态性与IS发病风险的独立相关性。结果:rs2277984多态性与IS易感性无相关性;rs3745565仅在显性遗传模式下、未进行校正时,其GC/CC基因型增加了IS的发病风险(OR=1.37,95%CI 1.04~1.80,P=0.026),在调整混杂因素后与IS易感性不相关(P>0.05)。结论:C3基因多态性的2个基因位点可能不影响本地区IS的发病风险。
Objective:To explore the association of genetic polymorphisms in complement component C3 with ischemic stroke risk in the ethnic Han of Eastern China.Methods:A total of 700 cases with ischemic stroke and the control group of 700 cases were recruited.Polymorphisms were rs2277984 G/A,rs37455652 G/C genotyped by TaqMan fluorescence probe.The multivariate Logistic regression model was used to exclude the effects of conventional risk factors on ischemic stroke.Results:The rs2277984 variant was not associated with ischemic stroke risk;the rs3745565 GG/CC genotype,only if under the dominant genetic model and uncorrected, had an increased risk of ischemic stroke(OR = 1.37,95% CI 1.04-1.80,P = 0.026).The rs3745565 variant was not associated with ischemic stroke risk after adjusting confounding factor(P 0.05).Conclusion:The present study suggested that genetic polymorphisms in complement component C3(rs2277984 and rs3745565) may not exert influences on ischemic stroke susceptibility among the ethnic Han of Eastern China.
