Abstract
放射性肺损伤(radiation induced lung injury, RILI)是临床上胸部肿瘤患者放疗后发生的严重并发症,主要表现为气短、低热、咳嗽等,严重影响患者生存,如何更好地防治RILI是亟待探索的问题。RILI的发生机制主要包括靶细胞学说、细胞因子学说、自由基学说、血管内皮细胞损伤学说。其中放疗产生的活性氧(reactive oxygen species, ROS)对组织的损伤贯穿整个RILI病程,对放射性肺炎和放射性肺纤维化均具有直接促进作用。包括巯基化合物、抗氧化酶、植物抗氧化剂等在内的治疗手段已被用于防治RILI,本文即就抗氧化治疗在RILI中的研究与应用作一综述。
