“High fat diet feeding, STZ intraperitoneal injection combined with traumatizing yin medicine gavage can successfully establish the rat model of both qi and yin deficiency syndrome of DMA. Shenqi compound can effectively alleviate the syndrome of "both qi and yin deficiency", regulate glucose and lipid metabolism, restore hemodynamics and coagulation function, reduce the degree of vascular lesions, and early prevent and treat DMA. Researchers have explored the method of constructing the rat model of both qi and yin deficiency syndrome of diabetes macroangiopathy, opening up a new direction for TCM syndrome model research and DMA prevention and treatment.”
