Aim: We studied the effects of different waves of ultraviolet radiation (UV) on DNA damage in different cells, and established the model of DNA damage and repair of K562 cell induced by UVC.

• 目的:研究不同波段紫外线(ultraviolet radiation,UV)对不同细胞DNA损伤的效应,用UVC及K562细胞构建了细胞DNA损伤修复的研究模型,对UVC介导的细胞DNA损伤与损伤修复的机制进行初探。
