    Abstract:

    Objective:To explore the effect of sevoflurane postconditioning on renal ischemia/reperfusion injury,and to determine whether its protective mechanism is related to the anti-inflammation and anti-oxidation. Methods:Male C57BL/6 mice were randomly and equally divided into four groups:sham operation group(Sham group),sham operation+ sevoflurane postconditioning group(Sham+Sevo group),renal ischemia/reperfusion injury group(IR group)and renal ischemia/reperfusion injury + sevoflurane postconditioning group(Sevo-Post C group). The renal ischemia/reperfusion injury model was induced by left renal pedicle clamping for 30 min followed by 24 h reperfusion and right nephrectomy. The mice were inhaled 2% sevoflurane for 1 h at the start of reperfusion in Sevo-Post C group. After 24 h reperfusion,renal functional parameters,serum mediator concentrations and markers of oxidative stress in kidney tissues were determined,and renal histopathological analysis was performed. The protein including p-Akt,p-GSK3β,Akt and GSK3β were determined by Western blot. Results:Serum creatinine(Scr),blood urea nitrogen(BUN),TNF-α,IL-6,and MDA concentrations were significantly increased after renal I/R as compared with the sham group(P<0.05). Sevoflurane postconditioning reduced Scr,BUN,TNF-α,IL-6,and MDA levels(P<0.05),and decreased histological scores(P<0.05). The phosphorylation levels of renal Akt and GSK3β were elevated after renal ischemia/reperfusion injury,and sevoflurane postconditioning further increased the phosphorylation levels of them as compared with the IR group(P<0.05). Conclusion:Sevoflurane postconditioning protected against renal IR injury possibly through the anti-inflammatory and antioxidative effects induced by the activation of Akt/ GSK3β signialing pathway.
