维生素D受体和脂联素基因多态性和非酒精性脂肪肝易感性临床关系研究

目的 探讨分析维生素D受体和脂联素基因多态性和非酒精性脂肪肝易感性临床关系.方法 选取102例非酒精性脂肪肝患者作为观察组,另选取100例健康志愿者作为对照组.对维生素D受体和脂联素基因多态性进行检测,比较两组维生素D受体和脂联素基因型分布和等位基因频率,并分析其和非酒精性脂肪肝易感性临床关系.结果 观察组维生素D受体BsmI位点、脂联素45和276位点基因型分布情况和对照组比较差异均有统计学意义(P＜0.05);观察组维生素D受体BsmI位点B等位基因频率远远低于对照组,而前者维生素D受体 45-T和276-G等位基因频率均远远高于后者,两组间各项数据比较差异均有统计学意义(P＜0.05);多因素非条件Logistic回归分析显示,维生素D受体:bb基因型、脂联素45位点:TT 基因型以及丙氨酸转氨酶(ALT)、三酰甘油(TG)、合并高血压史、胰岛素指数(HOMA-IR)均为影响非酒精性脂肪肝患者的独立危险因素.结论 维生素D受体和脂联素不同位点基因型分布在非酒精性脂肪肝患者中存在明显异常,二者和其易感性存在紧密关联.

Study on clinical relationships between gene polymorphism of vitamin D receptor and adiponectin with susceptibility of non-alcohol fatty liver disease

Objective To discuss and analyze the clinical relationships between the gene polymorphism of vitamin D receptor and adiponectin with the susceptibility of non-alcohol fatty liver disease(NAFLD).Methods One hundred and two cases of NAFLD were selected as the observation group,and other 100 healthy volunteers were selected as the control group.The gene polymorphism of vitamin D receptor and adiponectin in the two groups was detected,then the genotype distribution and allele frequencies of vitamin D receptor and adiponectin were compared between the two groups,then their relationship with the susceptibility of NAFLD was analyzed.Results The genotype distribution situation of vitamin D receptor BsmI site,adiponectin 45 and 276 sites had statistically significant difference between the observation group and control group(P＜0.05).The B allele frequency of BsmI site of vitamin D receptor in the observation group was far lower than that in the control group,and the allele frequencies of 45-T and 276-G of vitamin D receptor in the former were far higher than those in the latter,and the differences between the two groups were statistically significant(P＜0.05).The multivariate unconditional Logistic regression analysis showed that vitamin D receptor:bb genotype,adiponectin 45 locus:TT genotype and ALT,TG,complicating hypertension history and HOMA-IR all were the independent risk factors in NAFLD patients.Conclusion The genotype distribution of different sites of vitamin D receptor and adiponectin has obvious abnormality in the patients with NAFLD,and both are closely related with the NAFLD susceptibility.
