内毒素诱导的肝脏功能障碍是脓毒症等全身细菌感染合并的常见表现,目前缺乏特异性治疗手段,氢气在各类炎症等氧化损伤相关疾病中具有治疗作用,但氢气是否在内毒素诱导的急性肝脏功能障碍中具有保护作用过去没有见报道。最近来自中国医科大学盛京医院麻醉科的一项研究发表在Physiol Res上。作者对肝脏功能、细胞凋亡、氧化指标、炎症因子以及相关细胞内信号调节分子进行了全面分析,结果发现氢气生理盐水注射对内毒素诱导的肝脏急性炎症反应、氧化应激和细胞凋亡具有理想的保护作用,上述作用和MAPK、 NF-kappaB, 和Smac关系密切。提示氢气对细菌感染引起的肝脏损伤具有潜在的治疗价值。这是中国医科大学发表的第三篇关于氢气生物学的研究论文,过去该学校曾经发表2篇关于氢气治疗老年性痴呆治疗方面的研究。
氢气对肝脏疾病治疗的研究目前包括脂肪肝、脂肪肝肝病、原发性肝癌、各类肝硬化、肝脏缺血再关注、寄生虫感染肝炎、脓毒症肝损伤以及人类病毒性肝炎。
研究表明,氢气对各类肝脏疾病具有理想的治疗效果,根据目前掌握的研究结果,特别值得推荐的是目前常见的脂肪肝和非酒精性肝硬化,这对于预防原发性肝癌具有潜在的价值。不过,目前除我国曾经开展病毒性肝炎氢水治疗的研究外,国际上并没有临床研究的报道,这是该领域需要重视的研究方向。研究的重点是中期(3月-1年左右)对肝脏功能、影像学(超声、CT等)改变的影响,长期(2年以上)对原发性肝癌的预防价值。目前国内已经有企业开发出可以供人饮用的氢水,具备开展这类临床研究的条件。希望临床研究学者重点关注。

To determine the effect of saturated hydrogen saline onlipopolysaccharide(LPS)-induced acute liver dysfunction, rats were divided intocontrol, LPS, andLPS plus saturated hydrogen saline (LPS+H(2)) groups. Treatmentwith saturated
hydrogen saline prolonged the median survival time andreduced liver dysfunction.Moreover, saturated hydrogen saline significantlyreduced pathologicalalterations in liver tissues, the number of balloonedhepatocytes, serum tumor
necrosis factor (TNF)-alpha and interleukin (IL)-6levels, and myeloperoxidase(MPO) and malondialdehyde (MDA) levels in livertissues (P<0.05). Cell apoptosis was detected in liver tissues after LPStreatment, and attenuated by saturated
hydrogen saline treatment. Saturated hydrogen saline alsodecreased phosphorylated extracellular signal-regulated kinase (p-ERK),phosphorylated Jun kinase (p-JNK), nuclear factor-kappa B (NF-kappaB), andsecond mitochondria-derived activator of caspase (Smac) levels, and increasedp38
activation (P<0.05). Thus, saturated hydrogen salinemay attenuate LPS-induced acute liver dysfunction in rats, possibly by reducinginflammation and cell apoptosis. Mitogen-activated protein kinase (MAPK),NF-kappaB, and Smac may contribute to saturated hydrogen saline-mediated liverprotection.
