Abstract
Objective To investigate the effects of sufentanil on myocardial cells and renal function in rat models of non-stopping coronary artery bypass grafting.Methods SD rats were randomly divided into sham group(only thoracectomy without coronary artery ligation),model group(ischemia perfusion model was constructed),experimental-L group(ischemia perfusion model+0.5 μg·kg-1 sufentanil)and experimental-H group(ischemia perfusion model+1μg·kg-1 sufentanil).The mice were sacrificed 6 h after operation.The expressions of tumor necrosis factor-α(TNF-α),interleukin-1 β(IL-1 β)and interleukin-6(IL-6)in cardiomyocytes and renal cells were detected by enzyme-linked immunosorbent assay(ELISA).The expressions of apoptosis-related proteins in cardiomyocytes and renal cells were detected by Western blot.Serum renal function was detected with serum renal function kit.Results The expression levels of TNF-α in myocardial cells were(50.41±6.03),(136.61±21.73),(102.36±12.84)and(74.21±16.32)pg·mg-1 in sham group,model group,experimental-L group and experimental-H group,respectively;the expression levels of cysteinyl aspartate specific proteinase-3(Caspase-3)were 0.31±0.02,1.26±0.18,0.83±0.12 and 0.67±0.08,respectively;blood urea nitrogen(BUN)levels were(5.94±1.12),(20.04±5.36),(16.84±4.19)and(10.96±3.64)μmol·L-1,respectively;the expression levels of TNF-α in renal cells were(146.49±16.13),(1 023.82±34.69),(841.65±49.66)and(324.84±48.93)pg·mg-1,respectively;the expression levels of Caspase-3 in renal cells were 0.48±0.06,1.15±0.17,0.96±0.06 and 0.74±0.07,respectively.The difference between experimental-H group and sham group,model group and experimental-L group were statistically significant(all P＜0.05).Conclusion Sufentanil can significantly reduce the production of inflammatory factors and the expression of apoptotic proteins in rat cardiomyocytes,significantly improve the renal function of rats,and significantly reduce the production of inflammatory factors and the expression of apoptotic proteins in rat renal cells.
