(杨有利,等.西北国防医学杂志,2012,33(4):401～403.)高原缺氧不仅可引起生理功能异常,也可引起脏器实质损伤,高海拔环境可能导致机体抗氧化能力下降,导致氧化与抗氧化平衡失调,引起氧自由基损伤。当脱离高原环境返回到常压富氧的平原环境后,经过一个时期的重新适应,绝大多数生 (Yang Youli, et al., Northwest National Medical Journal, 2012,33 (4): 401 ~ 403.) Plateau hypoxia can not only cause abnormal physiological functions, but also cause physical damage to organs, high altitude environment may lead to the body’s antioxidant capacity Decline, leading to imbalance of oxidation and anti-oxidation, causing oxygen free radical damage. After leaving the plateau environment to return to atmospheric oxygen-rich plain environment, after a period of re-adaptation, the vast majority of students
