胆管阻塞可引起胆汁淤积,不仅对肝脏可造成严整损伤,引起肝脏急性损伤和纤维化,长期胆汁淤积可导致肝硬化和肝昏迷。由于可导致严重黄疸,容易引起全身性系统性症状,一直是肝胆外科领域长期 胆管阻塞引起肝损伤的机制比较复杂,但氧化损伤是其中比较重要的环节。根据最近国内外发现氢气具有抗氧化作用,能治疗氧化应激性疾病。医院杨甲梅课题组,利用大鼠动物模型,首次在国际上证明,氢气生理盐水能通过提高肝脏抗氧化能力,抑制肝脏炎症反应,从而具有明显治疗胆管阻塞后肝损伤的作用。该研究扩展了氢气治疗疾病的研究范围,为氢气在肝硬化的临床应用奠定了重要基础。医院刘渠等,从线粒体氧化损伤角度,对氢气的这一效应进行了更为深入具体的研究,研究论文在MolMedRep.Mar1发表。
氢气可选择性清除羟基自由基础,在许多氧化损伤动物模型中证明有治疗效果。氢气生理盐水是用氢气饱和的生理盐水,能提供高浓度的含氢气液体,使用安全方便,是一种比较理想的给氢气方式。最近,中国氢气医学健康产品呈现出爆发增长的趋势,各种氢水和呼吸氢气相关产品不断出现,将给氢气医学的临床研究和应用提供重要产业支持和转化条件。
