DA model was established by intravenously injected alloxan combined with high-fat diet and abdominal aortic balloon injury. After mediation for 10 weeks, fasting blood glucose(FBG), glycosylated hemoglobin(GHB), glycosylated serum protein(GSP), fructoseamine(FRA), aldose reductase(AR), advanced glycation end products(AGEs) in serum were measured by enzyme linked immunosorbent assay(ELISA) method;the expression of receptor of AGEs(RAGE) in myocardial tissue were observed by immunohistochemical method;and p-Jun N-terminal kinase(p-JNK), caspase-3, B-cell lymphoma-2(bcl-2) protein expression in myocardial tissue were measured by Western blotting. The myocardial apoptosis was detected by Td T-mediated d UTPnick-end labeling(TUNEL) method, and apoptosis index(AI) was calculated. Results: Compared with the control group, serum FBG, GHB, GSP, FRA, AR, AGEs and the expression of myocardium RAGE, p-JNK, caspase-3 proteins, as well as apoptosis index(AI) were significantly increased and bcl-2 protein was significantly decreased in the model group(P<0.01). Compared with the model group, the levels of serum FBG, GHB, GSP, FRA and AR showed a significant decline in CONR high-and medium-dose groups(P<0.01). FBG and GHB showed a significant decline in CONR low-dose group(P<0.01). Compared with the model group, the expression of serum AGEs and myocardium RAGE, p-JNK and caspase-3 protein as well as AI were significantly decreased and bcl-2 protein was significantly up-regulated in all treatment groups(P<0.01);high-dose CONR had the most significant effect on abovementioned indices compared with other treatment groups(P<0.01). Middle-dose CONR had better effect on serum AGEs compared with the low-dose group(P<0.01);middle-dose CONR and simvastatin groups had better effect on the expression of caspase-3, bcl-2 protein, myocardium apoptosis compared with the CONR low-dose group(P<0.01). Conclusion: CONR may effectively inhibit myocardial apoptosis on DA rabbits by intervening AGEs-RAGE and JNK, caspase-3, and bcl-2 protein expressions.展开更多
