摘要 锌是各种细胞功能所必需的很重要的矿物质,它的异常代谢与某些紊乱有关,譬如糖尿病并发症。对糖尿病心肌病而言,氧化应激是主要的诱导因素,锌在保护心脏免受各种氧化应激方面起着关键的作用。缺锌是心脏氧化损伤的一个危险因素,而补充锌对心脏的氧化损伤是一种重要的预防措施。糖尿病引起全身性的氧化应激,并且伴随锌的缺乏会增加心脏对氧化损伤的易感性。因此,一种有力的理论认为,锌补充剂可以预防或延缓糖尿病心肌病。有研究收集了在动物体内和体外条件下,锌补充剂对糖尿病诱导的心脏损伤具有预防效果的初步证据,讨论锌补充剂预防糖尿病心肌病的可能机制,包括锌抗氧化作用、胰岛素作用和金属硫蛋白诱导。讨论锌补充剂对糖尿病患者的预后情况。虽然锌补充剂未在临床上用于预防糖尿病综合症,但是实际上在其他临床紊乱疾病上正被使用,探索锌补充剂直接应用于临床对糖尿病心肌病的预防作用有积极的意义。
