目的:研究氢气对脊髓缺血再灌注损伤的保护作用及其潜在机制。方法新西兰兔随机分为3组:对照组、脊髓缺血再灌注损伤组和氢水治疗组。对照组仅接受暴露,无脊髓缺血再灌注损伤;缺血再灌注组动物采用ZIVIN法建立脊髓缺血再灌注损伤模型,造成脊髓腰骶段缺血35 min后行再灌注;氢水治疗组动物在再灌注前5 min腹腔注射饱和氢盐水(5 mL/kg),再灌注后8 h重复注射。不同时间点检测后肢运动功能。术后72 h取脊髓进行HE染色、TUNEL染色、氧化-抗氧化指标检测及ELISA检测细胞因子。结果含氢生理盐水治疗能显著改善动物神经功能、抑制脊髓神经元凋亡、抑制氧化应激、改善抗氧化能力,同时降低炎症相关细胞因子,从而发挥脊髓保护作用。结论腹腔注射含氢生理盐水通过抗氧化和抗炎对脊髓缺血再灌注损伤发挥保护作用。
目的:研究氫氣對脊髓缺血再灌註損傷的保護作用及其潛在機製。方法新西蘭兔隨機分為3組:對照組、脊髓缺血再灌註損傷組和氫水治療組。對照組僅接受暴露,無脊髓缺血再灌註損傷;缺血再灌註組動物採用ZIVIN法建立脊髓缺血再灌註損傷模型,造成脊髓腰骶段缺血35 min後行再灌註;氫水治療組動物在再灌註前5 min腹腔註射飽和氫鹽水(5 mL/kg),再灌註後8 h重複註射。不同時間點檢測後肢運動功能。術後72 h取脊髓進行HE染色、TUNEL染色、氧化-抗氧化指標檢測及ELISA檢測細胞因子。結果含氫生理鹽水治療能顯著改善動物神經功能、抑製脊髓神經元凋亡、抑製氧化應激、改善抗氧化能力,同時降低炎癥相關細胞因子,從而髮揮脊髓保護作用。結論腹腔註射含氫生理鹽水通過抗氧化和抗炎對脊髓缺血再灌註損傷髮揮保護作用。

To investigate the protective effect of hydrogen rich saline on the ischemia-reperfusion ( I/R) injury of the spinal cord in rabbits .Methods New Zealand rabbits were randomly assigned into 3 groups:control group, I/R group and hydrogen group .Animals in control group received sham operation;animals in I/R group underwent I/R of the spinal cord (35 min ischemia and 72 h reperfusion) with ZIVIN method; animals in hydrogen group were intraperitoneally treated with hydrogen rich saline at 5 min before reperfusion and 8 h after reperfusion .At different time points , the neurological functions were determined .At 72 h after reperfusion , animals were sacrificed and the spinal cord was collected for HE staining , TUNEL staining , detection of oxidative and anti-oxidative parameters and cytokines .Results Intraperitoneal treatment with hydrogen rich saline could improve the neurological functions , inhibit the apoptosis of neurons of the spinal cord , suppress the oxidative and elevate anti-oxidative capabilities and reduce the inflammation related cytokines .Conclusion Hydrogen rich saline may exert neuroprotection on rabbits undergoing I/R of the spinal cord via anti-oxidation and anti-inflammation.
