目的：探讨内皮型一氧化氮合酶基因 T-786C（eNOS T-786C）多态性与新疆地区维吾尔族心房颤动（房颤）患者的关系。方法选取新疆医科大学第一附属医院综合心脏内科收住的维吾尔族非瓣膜性房颤患者100例作为房颤组，维吾尔族非房颤患者100例作为对照组，收集样本，提取外周血 DNA，运用聚合酶链反应（PCR）方法及 DNA 测序进行多态性检测，并对突变位点进行定位及鉴定。结果房颤组年龄、低密度脂蛋白明显高于对照组（P ＜0．001）。房颤组与对照组样本 eNOS T-786C 基因多态性基因型符合哈迪-温伯格（Hardy-weinberg）平衡（房颤组χ2＝2．72，P ＝0．26；对照组χ2＝2．87，P ＝0．24）；房颤组 eNOS T-786C 基因 TT、TC、CC基因型频率分别为0．80（80／100）、0．17（17／100）和0．03（3／100），对照组分别为0．76（76／100）、0．20（20／100）和0．04（4／100），两组基因型分布差异无统计学意义（P ＞0．05）。房颤组 C 等位基因频率（0．115）与对照组（0．140）差异无统计学意义（P ＞0．05）。结论新疆地区维吾尔族心房颤动的发生与 eNOS T-786C 多态性无明显相关性。

Objective To investigate the relationship between endothelial nitric oxide synthase gene T-786C polymorphism and atrial fibrillation(AF)in Uyghur patients in Xinjiang.Methods 100 cases of Uyghur patients with non valvular atrial fibrillation (NVAF)were selected as AF case group,100 cases of non at-rial fibrillation patients as the control group,DNA samples was extracted from the peripheral blood,using polymerase chain reaction (PCR)method and DNA sequencing to detect the polymorphism,localization and identification of mutations.All experimental data were statistically analyzed.Results The age and low density lipoprotein cholesterol (LDL-C)in AF group was significantly higher than that in control group (P< 0.001 ).eNOS T-786C polymorphism genotypes in AF group and control group sample was in the balance of Hardy-Weinberg (AF group χ2 =2.72,P =0.26;control group χ2 =2.87,P =0.24).eNOS gene T786C,TT,TC CC genotype frequency in atrial fibrillation group was 0.80 (80/100),0.17 (17/100) and 0.03 (3/100),respectively,in the control group was 0.76 (76/100),0.20 (20/100)and 0.04 (4/100), respectively.Genotype distribution of the two groups have no statistical significance (P >0.05).There was no significant difference between the C allele frequency (0.115)and the control group (0.140)(P >0.05). Conclusion Endothelial nitric oxide synthase gene T-786C polymorphism was not have a quite significant correlation in Uyghur atrial fibrillation in Xinjiang.
