摘要/Abstract

摘要： 目的：探讨淫羊藿苷联合胚胎干细胞对造影剂肾病（CIN）大鼠模型肾上皮细胞的作用及其可能的机制，为临床上淫羊藿苷联合应用提供实验依据。方法：选取SD大鼠50只，随机分为对照组、模型组、淫羊藿苷组、干细胞组和联合给药组，每组10只，除对照组外其他各组大鼠尾静脉注射吲哚美辛（INDO）、N-硝基-LO-精氨酸甲酯（L-NAME）和泛影葡胺建立CIN大鼠模型。检测造模前后血肌酐（Scr）值；采用半定量RT-PCR和Western blotting法检测细胞凋亡相关因子p38MAPK和caspase3 mRNA和蛋白的表达，流式细胞术定量检测肾上皮细胞凋亡率。结果：Scr测定，注射造影剂48 h后，大鼠Scr值明显升高，提示造模成功。与模型组比较，联合给药组大鼠Scr值明显下降（P < 0.05）。与模型组比较，淫羊藿苷组、干细胞组和联合给药组大鼠p38MAPK和caspase-3 mRNA和蛋白表达水平降低（P < 0.05）；联合给药组大鼠肾上皮细胞凋亡率明显低于淫羊藿苷组和干细胞组（P < 0.05）。结论：联合给药对CIN模型大鼠的肾上皮细胞有保护作用，其作用机制可能与抑制细胞凋亡通路中相关因子有关。

Abstract: Objective: To investigate the effect of icariin combined with embryonic stem cells on the renal epithelial cells in the contrast-induced nephropathy(CIN) rats and its possible mechanism, and to provide experimental evidence for clinical application of icariin. Methods: Fifty SD rats were randomly divided into,control group, model group, icariin group, stem cell group and combination group(n=10).The rat models were established by tail vein injection of INDO, L-NAME and diatrizoate. The serum creatinine (Scr) levels of the rats were detected before and after modeling.The expressions of p38MAPK and caspase-3 mRNA and protein were detected by semi-quantitative RT-PCR and Western blotting method. The apoptotic rate of renal epithelial cells was detected by flow cytometry. Results: The levels of Scr of rats were significantly increased 48 h after combination contrast agent injection, suggesting that the CIN models were successfully set up.Compared with model group,the Scr level of the rats in group was significantly decreased (P<0.05). compared with model group the expression levels of p38MAPK and caspase-3 mRNA and protein in icariin group and stem cell group and in combination group were decreased (P<0.05).The apoptotic rate of renal epithelial cells in combination group was significantly lower than those in icariine and stem cell groups (P<0.05). Conclusion: Icariine combined with embryonic stem cells has a protectice effect on the renal epithelial cells in the CIN rats, and its mechanism may be related to the inhibition of the related factors in the apoptosis pathways.
