硫化氢治疗阿尔茨海默病的机制研究进展
Research advances of mechanism of treating Alzheimer's disease by hydrogen sulfide

内源性气体介质——硫化氢(H2S)，可调节哺乳动物一系列生理病理过程。近年来，中枢神经系统(CNS)内H2S的生理病理作用引起大家广泛关注。H2S作为神经调质，可促进海马长时程增强和调节脑细胞内Ca2+浓度和pH值。H2S可保护神经系统免受氧化应激、细胞凋亡或变性损伤。阿尔茨海默病(AD)病理过程中存在H2S失调。文章就H2S保护AD的潜在机制研究作一综述。
： Hydrogen sulfide (H2S) is an endogenously generated gaseous mediator and can regulate a series of physiological and pathological processes of mammals. In recent years, the physiological and pathological effects of H2S on the central nervous system attract more and more attention. H2S can promote the longterm potentiation of hippocampus and regulate the intracellular calcium concentration and pH level of brain cells as a neuromodulator. H2S can also protect the nervous system from oxidative stress, apoptosis, or degeneration. Dysregulation of H2S is implicated in the pathological processes of Alzheimer's disease (AD). This paper reviews the potential mechanism of protective role of H2S in AD
