目的 调查老年人小肠脂肪酸结合蛋白(I-FABP)基因外显子2中54位点密码子A/T 单核苷酸多态性和不同基因型人群的血脂水平,探讨I-FABP基因多态性与老年人血脂水平的关系.方法 采用聚合酶链反应(PCR)、DNA限制性内切酶酶切等技术对72例汉族老年人54A/T I-FABP基因型进行分析；用全自动生化仪检测入选人群的血浆总胆固醇(TC)、三酰甘油(TG)、高密度脂蛋白胆固醇(HDL-C)和低密度脂蛋白胆固醇(LDL-C)水平.结果 基因型分组Thr54(-)组、Thr54(+)组各36例,Thr54(-)组与Thr54(+)组比较,TC为(4.50±0.73) mmol/L与(5.48±0.49)mmol/L、TG为(1.08±0.48)mmol/L与(2.02±0.53) mmol/L、LDL-C为(3.10±0.44)mmol/L与(3.50±0.66) mmol/L和HDL-C为(1.14±0.25)mmol/L与(0.96±0.23) mmol/L,差异有统计学意义(t值分别为-6.67、-7.84、-3.03、3.05,均P＜0.05).结论 I-FAB外显子2中54位点密码子A/T SNP与老年人群的血脂水平相关.
