目的：研究冠心病患者脂联素基因多态性与冠心病患病风险的相关性。方法：256例研究对象中冠心病组126例，对照组130例。采用聚合酶链反应-限制性片段长度多态性法对所有患者的脂联素基因-11，377C ＞ G 位点核苷酸多态性进行基因型分析，采用病例对照方法研究脂联素基因多态性与冠心病风险性的关系。结果：（1）脂联素基因-11，377C ＞ G 位点存在基因多态性，测得基因型为 GG、CG 及CC 型；（2）脂联素基因-11，377C ＞ G 多态性在冠心病组与对照组间的分布存在差异，与对照组比，冠心病组中 G 等位基因的频率有显著升高（P ＜0．05），C 等位基因的频率在冠心病组有显著的降低（P ＜0．05）；（3）脂联素基因-11，377C ＞ G 在急性冠脉综合征组和稳定型心绞痛组间分布无统计学差异（P ＞0．05）；（4）在冠心病组人群中，G 等位基因患者冠心病患病风险明显提高（P ＜0．05）。结论：在冠心病人群脂联素基因-11，377C ＞ G 多态性与冠心病的危险性有关， G 等位基因频率提高可能提示冠心病的患病风险升高。%Objective To investigate the relationship between the polymorphism of adiponectin -11 ,377C> G gene and the risk of coronary heart disease(CHD). Methods A total of 126 CHD patients and 130 healthy controls were enrolled and the frequency of each genotypes and allele gene of adiponectin -11 ,377C > G were detected by polymerase chain reaction fragment length polymorphism (PCR-RFLP). Results (1) The adiponectin gene -11,377C > G sites existed gene polymorphism and the three genotypes were GG, CG and CC. (2) There was statistical difference between CHD group and control group; The G allele frequency of CHD group was significantly higher than that in control group (P < 0.05); The frequency of the C allele gene in CHD group was significantly decreased (P < 0.05). (3) There was no statistical difference of frequency distribution of each genotype and allele gene of adiponectin -11,377C > G between acute coronary syndrome (ACS) group and stable angina group . ( 4 ) The risk of CHD were increased in CHD patients with G allele gene of adiponectin-11,377C > G (P < 0.05). Conclusions The polymorphism of adiponectin -11,377C > G is associated with the increased risk of CHD. The increased G allele gene frequency may represent the increased risk of CHD.
