Abstract 【Objective】To evaluate the effect of remifentanil preconditioning on the apoptosis of renal cells and expressions of Bcl-2 and Caspase3 after hepatic ischemia reperfusion in rats. 【Methods】Seventy-two adult male SD rats were randomly divided into three equal groups (n=24): the sham operation group (group S), ischemia reperfusion group (group I/R), and remifentanil group (group RPC). According to 4 different time points of ischemia and reperfusion [ischemia for 30 min (T1), reperfusion for 1h (T2), 3h (T3) and 6h (T4)], the rats were further subdivided into 4 subgroups within each group: S1, S2, S3, S4; IR1, IR2, IR3, IR4,; and RPC1, RPC2, RPC3, RPC4. The Hepatic ischemia reperfusion model in rats was established using Pringle's maneuver method. The serum levels of alanine aminotransferase (ALT) and creatinine (Cr) were examined at each time point mentioned above. After 6 hours of reperfusion, the pathological changes in the kidneys were observed. TUNEL staining was used to examine cell apoptosis, and Western blot was employed to examine protein expressions of Bcl-2 and Caspase3 in renal tissues of each group. 【Results】 Serum ALT and creatinine levels in the I/R group and RPC group increased after 30 min of ischemia-these changes were significantly higher than that in the S group (P<0.05). However, levels in RPC group were lower than those in the I/R group (P<0.05). The renal tissue structure of the rats in group S was normal. In the IR group, there were different degrees of pathological damage of renal tissue: renal tubular epithelial cell swelling, lack of structure, nucleus condensation, necrotic exfoliated epithelial cells, and inflammatory cell infiltration. The pathological damage was obviously improved following remifentanil preconditioning in RPC group. TUNEL staining revealed that there were significantly lower apoptotic cells in the S group than those in the I/R group and the RPC group (P<0.05), and that the degree in the I/R group was much higher than that in the RPC group (P<0.05). Western blot detection of apoptotic protein showed that the expression of Bcl-2 and Caspase3 in the I/R group were higher than those in the S group (P<0.05). After Remifentanil preconditioning in RPC group, the expression of Bcl-2 increased but Caspase-3 expression decreased (P<0.05).【Conclusion】 Remifentanil preconditioning has a protective effect on renal injury after hepatic ischemia reperfusion, and the protective mechanism may be involved in the regulation of renal cell apoptosis and the expression of Bcl-2 and Caspase-3.
