胆固醇结石与载脂蛋白B基因多态性的关系

目的 探讨胆固醇结石病与载脂蛋白（Ａｐｏ）Ｂ基因多态性的关系。方法 选择载脂蛋白Ｂ基因多态位点ＸｂａⅠ、ＥｃｏＲⅠ应用聚合酶链反应和限制性片段长度多态性（ＰＣＲ－ＲＦＬＰ）技术对１０１例胆固醇结石病作５０例对照者进行研究。结果 胆固醇结石组Ｘ等位基因频率显著高于对照组，具有Ｘ等位基因者其血脂总胆固醇（ＴＣ）、低密度脂蛋白胆固醇（ＬＤＬ－Ｃ）及ＡｐｏＢ水平显著高于非Ｘ者；胆固醇结石组和对照组在Ｅdisp

Relationship between polymorphisms of the apolipoprotein B gene and cholesterol gallstone disease

Objective To investigate the relationship between the apolipoprotein (Apo)B gene polymorphic sites Xbal, EcoRI and cholesterol gallstone disease. Methods Two polymorphic sites Xbal, EcoRI of ApoB gene were selected. Using polymerase chain reaction and restriction fragment length polymorphism technique 101 patients with cholesterol gallstone and 50 controls were investigated. Results The frequency of rare allele X was significantly higher in the patients with cholesterol gallstone than in the controls. Patients with X allele had higher TC, LDL-c and ApoB levels, significantly different from those without X allele. There were no difference between the patient group and the control one in EcoRI allele. Conclusion X allele might be the susceptible gene for cholesterol gallstone disease.
