Abstract:
Objective To explore the role of salidroside in HIRI and its related mechanism. MethodsA total of 90 male SD rats were randomly divided into the sham group, the model group, the low, medium and high dose group, 18 rats in each group. The low, medium and high dose group rats were injected with 7.5, 15, 30 mg/kg salidroside solution, and the sham group and model group were injected with saline in the same volume, one time per day. After 7 days, all the rats were set up with the model of IR except the rats in Sham groups. The AST and ALT of serum, contrast between groups liver tissue by Optical microscope with HE dyeing at 4, 8, 16 h after reperfusion. Western Blot was used to detect the expression of protein of MAPK, JNK, ERK and NF-κB.ResultsFour, 8, 16 h after reperfusion, the level of ALT (540.67 ± 15.91 U/L vs.697.67 ± 5.98 U/L, 307.50 ± 12.97 U/L vs.962.50 ± 17.63 U/L, 103.33 ± 3.95 U/L vs.198.17 ± 9.73 U/L) and AST (651.17 ± 7.39 U/L vs.944.67 ± 11.38 U/L, 415.50 ± 10.97 U/L vs.1561.83 ± 15.76 U/L, 168.33 ± 5.81 U/L vs. 280.33 ± 12.35 U/L) in the high dose group were significantly lower than those in the model group. Eight and 16 hours after reperfusion, the expression of MAPK (1.28 ± 0.19 vs. 2.10 ± 0.12, 1.64 ± 0.14 vs.1.89 ± 0.14), JNK (1.80 ± 0.10 vs. 2.42 ± 0.11, 0.84 ± 0.17 vs. 3.32 ± 0.19), ERK (2.43 ± 0.10 vs.5.95 ± 0.09, 2.07 ± 0.13 vs. 6.61 ± 0.14), NF-κB (2.32 ± 0.16 vs. 3.08 ± 0.10, 2.11 ± 0.13 vs. 2.74 ± 0.17) in the high dose group were significantly lower than the model group (P<0.05).Conclusions The salidroside could reduce the liver ischemia- reperfusion injury, and its mechanisms may rugulate the MAPK/NF-κB signaling pathways.
