目的 探讨汉族人群中细胞间黏附分子-1(ICAM-1)第4外显子+12959G/A、第6外显子+13848A/G基因多态性与心肌梗死(心梗)的相关性。方法 提取165例心梗患者(包括急性心梗和陈旧性心梗)和199名健康对照者的DNA,采用序列特异性引物扩增法和聚合酶链反应-限制性片段长度多态性技术检测ICAM-1+12959G/A、+13848A/G基因多态性,同时测定血脂及血清超敏C反应蛋白(hsCRP,采用定量酶联免疫吸附试验技术)水平。结果 湖北地区汉族人群中存在+13848A/G多态性,在心梗组中基因型分布为:AA型58.2%、AG型37.0%、GG型4.8%;对照组分别为45.7%、45.2%、9.0%,两组比较差异有统计学意义(P<0.05);基因型频率的相对风险分析发现,AA型患心梗的风险是GG型及AG型的1.651倍(OR=1.651,95%CI:1.089~2.504)。未检出+12959G/A多态性。结论 ICAM-1+13848A/G基因多态性与湖北地区心梗易感性有关,+ 13848A等位基因可能是心梗发病的重要易感基因。 |

Objective To investigate the association between intercellular adhesion molecule-1 (ICAM-1) gene + 12959G/A and + 13848A/G polymorphism and myocardial infarction (MI). Methods Polymerase chain reaction-sequence specific primers (PCR-SSP) technology and PCR-restriction fragment length polymorphism(PCR-RFLP) were used for the detection of ICAM-1 genotypes in 165 patients with MI(including acute MI and old MI) and 199 healthy controls. Plasma lipid levels and hyper sensitive C reactive protein (quantitive ELISA method was used) levels were measured in all subjects. Results + 12959G/A polymorphism was not detected in our study. The frequencies of AA, AG and GG Genotypes of + 13848A/G were 58.2% and 45.7%,37.0% among patients and 45? 2%,4.8% and 9.0% among controls, respectively. There were statistically significant differences in the distributions of the genotype frequencies(P < 0.05) between two groups,and the relative risk suffered from MI of AA genotype was 1.651 times of the GG and GA genotype(OR = 1.651,95 % C/ : 1 ? 089-2.504). Conclusion There was no + 12959G/A polymorphism found in Chinese people. The coding single nucleotide polymorphism + 13848A/G in the exon 6 of ICAM-l gene was associated to MI and the allele A might serve as a risk factor for MI in Chinese. |
