Abstract:
Objective To investigate the relationship between IL-6-174C/G and-572C/G site gene polymorphism with nonvalvular atrial fibrillation(NVAF) as well as the national differences of interleukin-gene polymorphism between Kazak and Han nationality in Xinjiang region.Methods Seventy-nine Kazak patients of NVAF(Kazak NVAF group),78 Han patients with NVFA (Han NVAF group),75 Han cases of non-AF and 79 Kazak cases of non-AF were selected in Xinjiang region.The venous bloods were collected from extracting DNA.IL-6 gene-174G/C and-572C/G polymorphism in various groups were analyzed by adopting the PCR-RFLP technique.Results The allele frequency of IL-6-572G/C site G in the NVAF group was significantly higher than that in the control group(x2 =4.076,P＜0.05).The allele frequency of IL-6 gene-572 G/C site G had statistical difference between the NVAF group and the control group(OR=1.519,95 ％CI:I.087-2.122,P＜0.05),but the distribution difference between the Han and Kazak control groups had no statistical significance(P＞0.05);the advanced age ≥75 years old)(OR=6.468,95 ％CI:2.427-17.240) and left atrial dimension(OR =1.053,95 ％ CI:1.022-1.085) were the independent factors of AF occurrence;the left ventricular ejection fraction was a protective factor for preventing AF occurrence.The allele frequency of IL-6 gene 174G/C site C and G had no statistical difference among various groups(P＞0.05).Conclusion The allele of IL-6-572 G/C site G is a risk factor of genetic predisposition in NVAF.IL-6-174G/C site gene polymorphism has no relation with the susceptibility of AF.
