Abstract:

AIM: To study the effect of lidocaine on the inflammatory response and vascular smooth muscle cells proliferation and migration of diabetic rats. METHODS: Serum, vascular tissue and primary cultured vascular smooth muscle cells of diabetic model rats and lidocaine-treated diabetic model rats were taken for study. RESULTS:Lidocaine could effectively inhibit the secretion of TNF-α, IL-8 and PAF inflammatory factors, it could be seen that lidocaine could reduce the inflammatory response induced by diabetic cardiovascular disease. Lidocaine could reduce the absorbance of Brdu kit, Ki-67 level, vimentin expression level and the migration area of smooth muscle cells in the scar experiment, indicating that lidocaine could effectively reduce the proliferation and migration of vascular smooth muscle cells. Lidocaine effectively inhibited STAT3 signaling pathway and reduced proliferation and migration of vascular smooth muscle cells. The results were statistically significant (P<0.05). CONCLUSION: Lidocaine can effectively reduce the inflammatory response in diabetic rat model by inhibiting the activation of AKT-STAT3 signaling pathway, and at the same time reduce the abnormal proliferation and migration of vascular smooth muscle cells, thereby improving the vascular wall structure reconstruction. Lidocaine may be a potential therapeutic agent for diabetic cardiovascular disease induced by inflammatory response.

Key words: diabetes, inflammation, vascular remodeling, lidocaine
