通过β-微球蛋白(β_2-MG)测定,对糖尿病(DM)无合并症组(1组);DM并有视网膜病变组(2组);DM并有蛋白尿组(3组),DM并有视网膜病变及尿蛋白组(4组),进行对比研究。结果1组β_2-MG均值为25.2±9.2μg/L,2组为37.5±16.5μg/L,3组为43.2±19.41μg/L,4组为59.6±2.96μg/L。经统计学处理1、2组P<0.05,2、3组P>0.05,1、3组及1、4组P<0.05。由于β_2-MG含量可反映 The patients with DM without retinopathy (DM group), DM group with retinopathy (DM group), DM with proteinuria group (DM group), DM And retinopathy and urinary protein group (4 groups), comparative study. Results The mean β_2-MG in group 1 was 25.2 ± 9.2μg / L, in group 2 37.5 ± 16.5μg / L, in group 3 43.2 ± 19.41μg / L, and in group 4 59.6 ± 2.96μg / L. The statistical analysis of 1, 2 group P <0.05,2,3 group P> 0.05,1,3 group and 1,4 group P <0.05. As β_2-MG content can be reflected
