【 摘 要 】

It has been shown that local anesthetics have potential neurotoxicity, but the exact mechanism remains unclear. In this study, PC12 cells were treated with different concentrations of ropivacaine mesylate (0.1, 0.5, 1, 2 and 4 mmol/L) for 24 h, the cell viability was assessed by CCK-8 assay. Then, cells in 0.5 mmol/L ropivacaine group, 2 mmol/L ropivacaine group and control group were subjected to morphological observation under a light microscope, assessment of cell necrosis by Hoechst33342/PI staining and apoptosis by Annexin V-FITC/PI staining, and the detection of Fas and FasL expression by qPCR, immunofluorescence and Western blot. Results showed that the cell viability decreased significantly (P<0.05), necrosis and apoptosis rate increased markedly (P<0.05), and the expression of Fas, FasL, caspase-3 and caspase-8 increased dramatically (P<0.05) with the increase in the concentration of ropivacaine mesylate. Therefore, ropivacaine mesylate may induce the apoptosis of PC12 cells, which may be related to the up-regulation of Fas/FasL.
