汤剂治疗早期糖尿病肾病的研究进展

糖尿病(DM)是现代疾病中的第二代杀手,其主要危害在于其并发症,如酮症酸中毒、脑血管意外、心肌梗死、糖尿病.肾病(DN)等.自从胰岛素及各类降糖药问世以来,糖尿病酮症酸中毒的发生率和致死率明显下降,而大血管及微血管病变等并发症呈攀升趋势,如DN.DN一旦发展到尿毒症期,仅有透析才能改善患者的.     

胰腺内皮细胞共培养对C3A细胞功能变化的影响

Objective To investigate the functional changes of C3A cells co-cultured with pancreatic endothelial cells. Methods C3A cells and pancreatic endothelial cells lwere cultivated directly and indirectly for 7 days by the density ratio of 10: 1. Meanwhile, the blank control was established.The growth and morphological characteristics of experimental groups were observed. The out leakage level of AST, ALT and the synthesis level of albumin and the diazepam metabolism level were determined by automatic biochemistry analyzer, radioimmunoassay and enzyme linked immunosorbent assay. Results Direct co-cultivation of C3A cells and pancreatic endothelial cells could reduce the out leakage of ALT and AST in the 5th and 7th d. The capacity of albumin synthesis could reach 12. 977μg/ml on the 7th d and the that of diazepam metabolism could also be improved. Indirect co-cultivation of C3A cells and pancreatic endothelial cells could significantly raise the albumin synthesis to 7. 380 μg/ml and 10. 773 μg/ml on the 5th and 7th d, respectively. Conclusion Co-cultivation of C3A cells and pancreatic endothelial cells can significantly improve the basic biological function of C3A cells.

胰腺内皮细胞共培养对C3A细胞功能变化的影响

目的 探讨与胰腺内皮细胞共培养时C3A细胞功能变化.方法 选择C3A细胞与胰腺内皮细胞的密度比例为10:1分别进行直接和间接共培养7 d,同时设立空白对照组,观察各实验组细胞生长和形态特征,分别用杜邦全自动生化分析仪、放射免疫分析法和ELISA法检测培养液中AST、ALT漏出量,白蛋白含量和安定代谢量.结果 C3A细胞与胰腺内皮细胞直接共培养第5、7天能显著降低ALT、AST的漏出量,第7天提高白蛋白合成量最高达12.977μg/ml和提高安定代谢能力;C3A细胞与胰腺内皮细胞间接共培养在第5、7天也能显著提高白蛋白合成量到7.380μg/ml、10.773μg/ml.结论 与胰腺内皮细胞直接与间接共培养均能明显改善C3A细胞的功能.
