摘要: 目的:研究氢气对慢性间歇性低氧大鼠肝脏损伤的改善作用。方法:24只雄性成年SD大鼠,随机分为3组(n=8):常氧组(Norm)、慢性间歇性低氧组(CIH)、氢气+慢性间歇性低氧组(H2+CIH)。Norm组暴露于空气中,CIH组与H2+CIH组接受间歇性低氧处理5周,其中H2+CIH组在间歇性低氧处理前给予1 h 67%浓度的氢气吸入。5周后比较各组大鼠血清氧化应激指标、炎症因子指标、肝酶水平、血脂水平,并在电镜下观察大鼠肝组织超微结构变化。结果:与Norm组相比,CIH组肝组织超微结构受损严重,谷丙转氨酶(ALT)、谷草转氨酶(AST)水平显著升高(P<0.05);血清8-羟基脱氧鸟苷(8-OHdG)水平显著升高;超氧化物歧化酶(SOD)活性显著降低;白介素-6(IL-6)水平显著升高。与CIH组相比,H2+CIH组肝组织超微结构损伤减轻,ALT、AST水平显著降低(P<0.05);8-OHdG与IL-6水平显著降低,SOD活性显著升高。与Norm组相比,CIH组IL-1水平升高;血清TC、TG、LDL水平升高,但无统计学差异。HDL在各组之间无统计学差异。结论:氢气可以减轻慢性间歇性低氧对大鼠肝脏的损伤,有效降低氧化应激水平,保护肝细胞受损。

Abstract: Objective: To explore the effects of hydrogen on liver injury in chronic intermittent hypoxia rats and the related oxidative stress mechanism.Methods: Twenty-four male adult SD rats were randomly divided into 3 groups(n=8):the normoxia group (Norm), the chronic intermittent hypoxia group (CIH), the chronic intermittent hypoxia and hydrogen group (H2 + CIH). Rats in Norm group were exposed in air, those in the other 2 groups suffered from chronic intermittent hypoxia conditions for 5 weeks. Before the CIH treatment, rats in H2+CIH group inhaled hydrogen gas at 67% concentration for 1 hour. The serum biochemical indicators of oxidative stress, pro-inflammatory cytokine, liver enzyme and blood lipid were inspected after five weeks treatment, the pathological changes of liver tissue were also observed in the transmission electron microscope.Results: Compared with Norm group, the microstructure of liver cells was severely injured, and the serum levels of glutamic-pyruvic transaminase(ALT),glutamic-oxalacetic transaminase (AST) were significantly higher in CIH group (P<0.05); the serum level of 8-hydroxy-2 deoxyguanosine(8-OHdG) and interleukin-6(IL-6) was significantly higher, the serum level of superoxide dismutase (SOD) was significantly lower. Compared with CIH group, the pathology of liver microstructure were significantly improved and the serum levels of ALT, AST were significantly lower in H2+CIH group (P<0.05); the serum levels of 8-OHdG and IL-6 were significantly lower, the serum level of SOD was significantly higher. Compared with Norm group, the serum level of IL-1 was higher, the serum level of TC, TG, and low density lipoprotein(LDL) were lower, but there was no statistical difference with those in CIH group. There was no statistical difference in the serum level of high density lipoprotein (HDL)among the three groups.Conclusion: Pre-treatment with hydrogen could improve the liver injury caused by chronic intermittent hypoxia, and reducing oxidative stress level for protecting the liver cells damage.
