摘要

Molecular hydrogen (H2) is a physiologically inert gas.However,during the last 10 years,increasing evidence has revealed its biological functions under pathological conditions.More specifically,H2 has protective effects against a variety of diseases,particularly nervous system disorders,which include ischemia/reperfusion injury,traumatic injury,subarachnoid hemorrhage,neuropathic pain,neurodegenerative diseases,cognitive dysfunction induced by surgery and anesthesia,anxiety,and depression.In addition,H2 plays protective roles mainly through anti-oxidation,anti-inflammation,antiapoptosis,the regulation of autophagy,and preservation of mitochondriai function and the blood-brain barrier.Further,H2 is easy to use and has neuroprotective effects with no major side-effects,indicating that H2 administration is a potential therapeutic strategy in clinical settings.Here we summarize the H2 donors and their pharmacokinetics.Meanwhile,we review the effectiveness and safety of H2 in the treatment of various nervous system diseases based on preclinicai and clinical studies,leading to the conclusion that H2 can be a simple and effective clinical therapy for CNS diseases such as ischemia-reperfusion brain injury,Parkinson's disease,and diseases characterized by cognitive dysfunction.The potential mechanisms involved in the neuroprotective effect of H2 are also analyzed.
