Protective effect of compound drug Weng-Li-Tong on cisplatin-induced hepatocyte injury
Objective To investigate the protective effect of the compound drug Weng-Li-Tong(WLT)against cisplatin(CDDP)-induced hepatocyte injury.Methods A cellular injury model was established by treating murine hepatocyte line BNL CL.2 with CDDP(80 μmol/L).Experimental groups were divided as follows:CDDP group(modeling only),WLT group(intervention with 1 g/L WLT),WLT+CDDP group(co-administration of CDDP and 1 g/L WLT),and a control group(normal culture).The protective effect of the compound drug WLT on CDDP-mediated hepatocyte injury was evaluated using CCK-8 assay,PI staining,crystal violet staining,Western blotting,reactive oxygen species(ROS)detection,and apoptosis analysis.Results Compared with the control group,the number of dead cells increased significantly(P＜0.001)in the CDDP group,but no cytotoxicity was observed in the WLT group.The hepatocyte morphology in the WLT+CDDP group showed improvement with no obvious shrinkage compared to the CDDP group,as evidenced by the reduced proportion of PI-positive cells.Crystal violet staining results also indicated a higher cell count in the WLT+CDDP group than in the CDDP group,suggesting the protective effect of WLT against CDDP-mediated liver injury.Under CDDP intervention,the expression of the apoptosis-related protein Cleaved Caspase-3 increased.However,in the WLT+CDDP group,the expression of Cleaved Caspase-3 decreased,while the expression of the anti-apoptotic protein Bcl-2 increased.Additionally,compared to the CDDP group,the WLT+CDDP group showed a reduction in ROS production[DCFH-DA staining positive rate(％):56.20±1.65 vs.44.57±0.31]and a decrease in the proportion of apoptotic cells[proportion of early and late apoptotic cells(％):43.60±0.44 vs.19.57±0.78;33.30±1.02 vs.14.83±0.57].Conclusion The compound drug WLT exhibits a protective effect against CDDP-mediated hepatocyte injury,suggesting potential therapeutic value in acute liver injury models.
