醋酸纤维/聚乙烯基亚胺膜去除血清胆红素同时对肝病相关因子影响的研究

Experimental study on CA/PEI membrane to the factors relating to liver diseases along with the clearance of bilirubin

目的探讨醋酸纤维素/聚乙烯基亚胺(CA/PEI)膜在吸附血清胆红素同时对慢性肝病患者部分细胞因子、免疫球蛋白、补体的影响。方法应用CA/PEI膜吸附30例黄疸患者血清,ELISA法测定吸附前后白细胞介素-6(IL-6)、白细胞介素-10(IL-10)、肿瘤坏死因子-α(TNF-α)和转化生长因子-β1(TGF-β1)含量,免疫散射比浊法测定免疫球蛋白-A(IgA)、免疫球蛋白-M(IgM)、免疫球蛋白-G(IgG),补体-3(C3)和补体-4(C4)含量。结果吸附后IL-6、TNF-α和TGF-β1下降(P<0.05),IL-10无明显变化;免疫球蛋白和补体亦无变化。结论:CA/PEI膜在去黄同时可对肝病进展相关的一些血液成分有不同影响。

Objective To study the effect of CA/PEI membrane on cytokines, immunoglubin and complements along with bilirubin clearance in chronic liver diseases. Methods We used CA/PEI membrane to adsorb jaundice sera from 30 cases for 2 hours. Serum IL-6, IL-10, TNF-α and TGF-β1 were measured by ELISA before and after the adsorption. IgA, IgM, IgG, C3 and C4 were detected by immune scatter turbidimetry. Results After the adsorption, serum IL-6, TNF-α and TGF-β1 decreased （P〈0.05）, and IL-10, immunoglobulin and complements remained unchanged. Conclusion CA/PEI membrane may affect several cytokines relating to the progress of liver diseases in company with bilirubin clearance.
