摘要: 目的 了解趋化因子CXC配体16(CXC ligand 16,CXCL16)181A >V多态性等位基因及基因型在中国汉族人群的分布,探讨其基因及血清水平与动脉粥样硬化性卒中的相关性。方法 采用聚合酶链反应-限制性片段长度多态性(Polymerase chain reaction-restrictive fragmentlength polymorphism,PCR-RFLP)方法,检测244例动脉粥样硬化性卒中患者(卒中组)和204例对照者(对照组)CXCL16 181A >V位点的基因型分布特点,同时比较该多态性位点在中国对照组人群、德国人群与瑞典人群间的分布差异。同时,应用ELISA方法检测卒中组与对照组的血清CXCL16水平,并进行统计学分析。结果 卒中组高血压病史、糖尿病病史、吸烟史、饮酒史、总胆固醇(total cholesterol,TC)、低密度脂蛋白胆固醇(low-density lipoprotein cholesterol,LDL-C)、血清CXCL16水平高于对照组(P均<0.01),高密度脂蛋白胆固醇(high-density lipoprotein cholesterol,HDL-C)低于对照组(P <0.01)。CXCL16181A >V等位基因(P <0.01)及基因型分布(P =0.004)在中国组、德国组和瑞典组差异有统计学意义,而卒中组与对照组间差异无统计学意义(P =0.774,0.692)。结论 血清CXCL16水平升高与动脉粥样硬化性卒中的发生相关;CXCL16 181A >V位点基因多态性存在种族差异性,与中国汉族人群动脉粥样硬化性卒中可能无关。

Abstract: Objective To investigate the allele frequencies and genotype distribution of CXCL16 gene181A>V polymorphism, and to analyse the association of genotypes and serum levels of CXCL16with atherosclerotic stroke in Chinese Northern Han population.Methods To detect the CXCL16 181A >V genotype and allele frequency of 244 ateroscleroticstroke patients (CI group) and 204 normal subjects (control group) with polymerase chainreaction-restriction fragment length polymorphism (PCR-RFLP), and serum levels of CXCL16was determined by enzyme-linked immuno sorbent assay (ELISA).Results Statistical differences were detected between CI and controls in the levels of serumCXCL16 levels, fasting blood glucose, total cholesterol (TC), low-density lipoprotein cholesterol(LDL-C) and high-density lipoprotein cholesterol (HDL-C), and in hypertension history, type2 diabetes history, smoking history and drinking history (P <0.01); There were significantlydifferences in allele frequencies and genotypes in 181A>V polymorphism among races (P =0.004,<0.001), but not in CI group and control group (P =0.774, 0.692).Conclusion Increased serum CXCL16 levels is associated with atherosclerotic stroke in ChineseHan population, while 181A>V polymorphism is not related with atherosclerotic stroke.
