我院采用醋酸薄膜电泳法、分析40例肾炎患儿尿蛋白电泳中α_2+γ量的多少与血浆中A/G 比值对肾炎分型、预后的意义。并用Y 值作对比,发现尿蛋白中α_2+γ>15%、A/G>1.5:1时,Y 值均≤0.85,这些病例属膜性增殖型肾小球肾炎,对激素治疗不敏感、预后欠佳。反之,尿蛋白中α_2+γ<15%、A/G<1.5:1时、Y<0.85,其中76.5%为微小病变型肾小球肾炎,对激素治疗敏感,预后良好。 Acetate thin film electrophoresis was used in our hospital to analyze the significance of the ratio of α_2 + γ in urinary protein electrophoresis and the ratio of A / G in plasma on the classification and prognosis of nephritis in 40 nephritis children. The results showed that Y values ​​were all less than or equal to 0.85 in the case of α_2 + γ> 15% of urinary protein and A / G> 1.5: 1. These cases were membranous proliferative glomerulonephritis and were not sensitive to hormone therapy. Poor prognosis. Conversely, urinary protein α_2 + γ <15%, A / G <1.5: 1, Y <0.85, of which 76.5% is minimal change glomerulonephritis, sensitive to hormone therapy, the prognosis is good.
