Proliferation and migration of vascular smooth muscle cells (VSMC) are common pathological features of diabetic vascular complications,such as atherosclerosis and hypertension. Phenotypic modulation of VSMC is the basis for VSMC proliferation and migration. Therefore, studies on VSMC phenotypic modulation and its mechanisms in diabetes mellitus were of important significance to the prevention and therapy of diabetic vascular complications. This paper introduces VSMC phenotypic modulation and the underlying mechanisms in diabetes mellitus, and summarizes advance of studies on traditional Chinese medicine intervention upon VSMC phenotypic modulation, so as to provide reference for preventing and treating diabetic vascular complications with traditional Chinese medicines.
