Abstract:

Objective

To investigate the effect and mechanism of sevoflurane pretreatment on the liver ischemia-reperfusion injury (IRI) in diabetes mellitus mice model.

Methods

Twenty-four male db/db mice with type 2 diabetes mellitus, weighed 25-30 g each, were divided into the sham surgery group (Sham group), liver IRI group (IRI group), sevoflurane pretreatment group (S group) and sevoflurane pretreatment combined with ischemic-reperfusion group (SIR group), with 6 mice in each group. In Sham group, only the porta hepatis was exposed without blood occlusion. In IRI group, the hepatic portal occlusion was performed for 30 min and restored afterward. In S group, sham operation was conducted 120 min after inhalation of 2.4% sevoflurane. In SIR group, inhalation of 2.4% sevoflurane for 120 min was delivered before hepatic portal occlusion. The levels of serum ALT, AST, superoxide dismutase (SOD) and malondialdehyde (MDA) in liver tissue of each group were measured. The expression levels of nuclear factor-κB (NF-κB) and intercellular adhesion molecule-1 (ICAM-1) proteins in liver tissue were detected by Western blot. The tested results were compared using One-way ANOVA and LSD-t test.

Results

In SIR group, the level of serum ALT and AST was respectively (67±12) and (92±8) U/L, significantly lower than (88±12) and (117±15) U/L in IRI group (LSD-t=-4.18, -4.61; P<0.05). In SIR group, the SOD activity was (126±12) U/mg, significantly higher than (85±9) U/mg in IRI group (LSD-t=6.53, P<0.05). In SIR group, the MDA activity was (4.3±0.7) nmol/mg, significantly lower than (6.7±1.1) nmol/mg in IRI group (LSD-t=-5.85, P<0.05). In SIR group, the relative expression level of NF-κB and ICAM-1 protein was respectively 0.53±0.19 and 0.96±0.13, significantly lower than 0.97±0.13 and 1.29±0.11 in IRI group (LSD-t=-6.01, -5.63; P<0.05).

Conclusions

Sevoflurane pretreatment can mitigate IRI in diabetes mellitus mice, probably through enhancing the eliminating ability of free radicals, inhibiting NF-κB signaling pathway and down-regulating the expression of ICAM-1 in liver endothelial cells.
