急性心肌梗死患者凝血酶原基因G20210A变异频度分析

目的 :探讨FⅡG2 0 2 10A突变在中国人群中的分布频率及其与急性心肌梗塞之间的联系。方法 :运用FⅡG2 0 2 10A等位基因特异性引物PCR ,结合限制性内切酶技术及聚丙烯酰胺凝胶电泳等方法检测 97例急性心肌梗塞患者及 10 7例正常人对照的FⅡG2 0 2 10A基因频率。结果 :未检出 1例FⅡG2 0 2 10A基因突变者 ,提示被检病例及正常人FⅡG2 0 2 10A基因变异频率为 0。结论 :在中国人群中FⅡG2 0 2 10A基因变异罕见甚至缺如。FⅡG2 0 2 10A基因突变不足以成为中国人急性心肌梗塞的危险因素。

Relations of Budd-Chiari syndrome to prothrombin gene mutation

BACKGROUND: Budd-Chiari syndrome (BCS) is a type of disease characterized by portal hypertension and/or hy- pertension of the inferior vena cava (IVC) due to the ob- struction of the hepatic veins (HV) and/or intrahepatic IVC outlet. Being etiologically complicated and obscure, BCS can be acquired or idiopathic and several gene muta- tions may be contributable. This study was to explore whether prothrombin gene mutation (F G20210A) takes part in the pathogenesis of BCS and to investigate their cor- relativity. METHODS: In 38 proven BCS patients and 70 controls, polymerase chain reaction-restriction fragment length poly- morphism (PCR-RFLP) was used to find F G20210A mutation. To detect whether there are any mutations, four steps were taken: purification of genome DNA from whole blood, amplification of special fragment by polymerase chain reaction, digestion of the fragment via restriction en- donuclease, and analysis of results by polyacrylamide gel electrophoresis. RESULTS: F G20210A mutation was not detected in all patients and controls. CONCLUSIONS: No F G20210A mutation exists in Chi- nese patients with BCS, nor correlativity between the oc- currence of BCS and F G20210A mutation. The etiology of BCS in the Chinese needs further investigation.
