维生素D是一种脂溶性维生素,调节钙磷代谢,在骨骼代谢,骨质形成方面起重要作用。研究发现,维生素D除传统钙磷调节作用外,还参与炎性反应、免疫、糖脂代谢等病理、生理过程,维生素D通过受体发挥作用,是一种具有激素样作用机理的类激素样物质。近年来越来越多的研究表明维生素D可以预防和治疗糖尿病~([1-3]),但也有一些研究并不支持这一观点~([4-5])。本研究探讨了维生素D与2型糖尿病视网膜病变 Vitamin D is a fat-soluble vitamin that regulates calcium and phosphorus metabolism and plays an important role in bone metabolism and bone formation. The study found that in addition to the traditional calcium and phosphorus regulation of vitamin D, but also involved in inflammatory response, immune, glucose and lipid metabolism and other pathological and physiological processes, vitamin D through the receptor play a role with the hormone-like mechanism of action hormone-like substance. In recent years, more and more studies show that vitamin D can prevent and treat diabetes ~ ([1-3]), but some studies do not support this view (4-5). This study explored vitamin D and type 2 diabetic retinopathy
