CNS Neurosci Ther:氢气治疗脊髓损伤的机制研究

2014-06-17 孙学军 博客园

第二军医大学长征医院麻醉科学袁红斌教授课题组,前期研究证明,氢气对脊髓损伤的具有治疗作用,但对其治疗作用机制并不十分了解。最近袁红斌教授课题组进一步研究证明,氢气所以能治疗脊髓损伤,主要是通过抑制氧化损伤相关星形胶质细胞增生,并对和星形胶质细胞增生关系密切的细胞信号分子STAT3磷酸化、活性氧和相关炎症因子的变化进行的分析。该研究目前已经发表在CNS Neurosci Ther. 脊髓损伤是导

第二军医大学长征医院麻醉科学袁红斌教授课题组,前期研究证明,氢气对脊髓损伤的具有治疗作用,但对其治疗作用机制并不十分了解。最近袁红斌教授课题组进一步研究证明,氢气所以能治疗脊髓损伤,主要是通过抑制氧化损伤相关星形胶质细胞增生,并对和星形胶质细胞增生关系密切的细胞信号分子STAT3磷酸化、活性氧和相关炎症因子的变化进行的分析。该研究目前已经发表在CNS Neurosci Ther.

脊髓损伤是导致人类瘫痪的重要原因,给患者和家庭带来极大痛苦和经济负担。随着世界各国经济水平的发展,脊髓损伤发生率呈现逐年增高的趋势。在发达国家,脊髓损伤的发生率大约为13.3-45.9人/百万人/年,我国上海市1991年统计的脊髓创伤发生率为34.3人/百万人,北京市2002年脊髓创伤发病率为60人/百万人。脊髓损伤是脊柱创伤最严重的并发症,往往导致损伤节段以下肢体严重的功能障碍。脊髓损伤不仅会给患者本人带来身体和心理的严重伤害,还会对整个社会造成巨大的经济负担。在美国,由于脊髓损伤所导致的社会经济损失大约为80亿美元/年。针对脊髓损伤的预防、治疗和康复已成为当今医学界的一大课题。

值得注意的是,从目前所开展的研究看,氢气所以对脊髓损伤具有治疗作用,只是针对脊髓损伤后引起的局部组织氧化损伤、炎症反应和细胞增生产生的影响。中枢神经损伤后局部炎症是导致疾病加重的重要因素,对抗炎症和氧化损伤能产生一定效果是值得肯定的,当然动物实验结果不能直接证明人体有效,因此这方面仍需要开展临床研究确认。另外,从目前所了解治疗机制角度,氢气对脊髓损伤并不能解决神经再生的问题,因此对陈旧性脊髓损伤不可能产生效果。不过,脊髓损伤瘫痪的患者,可能存在消化道紊乱,缺乏运动带来的代谢性疾病问题,使用氢气治疗或许能产生理想效果。总之,氢气绝对不是万能药,不可能包治百病,但考虑到氢气的巨大安全性,以及其治疗基础是对抗氧化和炎症,对多种疾病都有可能产生一定效果,因此许多疾病都值得尝试。
