RESUMO
Objective:To investigate the correlation between interleukin-27(IL-27)polymorphisms and coronary heart disease(CHD)in the Guangxi Zhuang population.Methods:A total of 1 218 subjects were enrolled in this case-control study, and 571 cases were in the CHD group and 647 were in the control group.The Sequenom MassArray system was used to genotype IL-27 single nucleotide polymorphisms(SNPs), and other biochemical parameters were tested by using the standard protocol in the laboratory of our hospital.The correlation between IL-27 SNPs and CHD was evaluated by Logistic regression analysis, and risk factors including age, smoking, drinking, history of hypertension, history of diabetes mellitus and family history of CHD were adjusted in this model.Methods:Logistic regression analysis results indicated that the risk of CHD was elevated in subjects with the CC genotype of IL-27 rs428253, compared with those with the GG genotype( OR=2.18, 95% CI: 1.09-4.37, P<0.05). After adjustment for the related risk factors, the risk of CHD also increased in subjects with the CC genotype of IL-27 rs428253, compared with those with the GG genotype( R=2.82, 95% CI: 1.31-6.07, P<0.05). IL-27 rs4740, rs17855750, rs181206 and rs40837(all P>0.05)polymorphisms had no correlation with CHD in the Zhuang population, and there were no significant differences in C-reactive protein, total cholesterol, triglyceride or low-density lipoprotein cholesterol levels between CHD patients and controls with different genotypes of IL-27 rs428253(all P>0.05). Conclusions:IL-27 rs428253 polymorphism is correlated with the risk of CHD in the Guangxi Zhuang population.
