摘要: 目的 探讨慢性肾脏病患者载脂蛋白E(ApoE)基因多态性与不对称二甲基精氨酸(ADMA)水平的表达及其关联性。方法 选择2018年1月至2020年1月在连云港市第二人民医院心内科、肾内科住院的慢性肾脏病患者300例,采用慢性肾脏疾病流行病学协作(CKD-EPI)方法计算肾小球滤过率(GFR),按GFR对300例患者进行分组:Ⅰ组GFR >60 ml/min(86例),Ⅱ组15 ml/min <GFR ≤60 ml/min(119例),Ⅲ组GFR ≤15 ml/min或血液透析患者(95例)。用聚合酶链反应扩增法(PCR)检测ApoE基因多态性,采用酶联免疫吸附双抗体夹心法(ELISA)检测ADMA水平,比较各组等位基因和基因型分布。计量资料组间比较采用方差分析,计数资料比较采用χ2检验。结果 300例患者年龄(61.9±13.1)岁,男性151例(50.33%),体质量指数(BMI)(28.0±5.1)kg/m2,糖尿病88例(29.33%),心血管疾病174例(58.00%)。3组间糖尿病、冠心病比例及低密度脂蛋白、三酰甘油、肌酐、ADMA水平比较,差异均有统计学意义(均P<0.05)。ApoEε2等位基因35例(11.67%),ε3等位基因287例(95.67%),ε4等位基因58例(19.33%)。ApoE等位基因在不同肾功能分组中分布是均一的(均P>0.05);基于ADMA水平分组,ApoE基因多态性在不同ADMA水平组的分布中差异均有统计学意义(均P<0.05)。结论 随着GFR的降低,血浆ADMA水平显著升高;ApoE等位基因在不同肾功能分组中分布是均一的;ApoE等位基因在不同ADMA水平分组中分布是不均一的;肾功能异常等临床变量的存在限制了ApoEε4等位基因的表达。

Abstract: Objective To investigate the association between apolipoprotein E (ApoE) gene polymorphism and asymmetric dimethylarginine (ADMA) expression in patients with chronic kidney disease. Methods A total of 300 patients with chronic kidney disease hospitalized in the departments of cardiology and nephrology of Lianyungang Second People's Hospital from January 2018 to January 2020 were selected. The glomerular filtration rate (GFR) was calculated by the chronic kidney disease epidemiology collaboration (CKD-EPI) method, and 300 patients were stratified according to the GFR: group I with GFR >60 ml/min (86 cases), group Ⅱ with GFR >15 ml/min and ≤60 ml/min (119 cases), and group III with GFR ≤15 ml/min or hematodialysis (95 cases). The ApoE gene polymorphism was detected by polymerase chain reaction (PCR) amplification method, and the ADMA level was detected by double antibody sandwich enzyme-linked immunosorbent method (ELISA). The alleles and genotypes of each group were compared. ANOVA was used for comparison of the measurement data between groups, and χ2 test was used for comparison of the count data. Results The 300 patients were (61.9±13.1) years old, with 151 males (50.33%), body mass index (BMI) of (28.0±5.1) kg/m2, including 88 cases (29.33%) of diabetes and 174 cases (58.00%) of cardiovascular diseases. There were statistically significant differences in the proportions of diabetes and coronary heart disease and the levels of low density lipoprotein, triglyceride, creatinine, and ADMA among the three groups (all P<0.05). There were 35 cases (11.67%) of ApoEε2 allele, 287 cases (95.67%) of ApoEε3 allele, and 58 cases (19.33%) of ApoEε4 allele. Based on the renal function, allele distribution was uniform among the three groups (all P>0.05); based on the ADMA level, the distribution of ApoE gene polymorphism was different in different ADMA level groups (all P<0.05). Conclusions With the decrease of the GFR, the plasma ADMA level increases significantly. The distribution of ApoE alleles is uniform among different renal function groups. The distribution of ApoE alleles is not uniform in different ADMA level groups. The presence of clinical variables such as renal dysfunction limits the expression of ApoEε4 allele.
