Experimental study of red light therapy instrument combined with insulin on type 2 diabetic foot model rats

摘要

Objective: To investigate the therapeutic effect and clinical value of red light therapy combined with insulin therapy on wound in type 2 diabetic foot (DF) rats. Methords: Wistar rats were injected intraperitoneally with medium-dose high-fat and high-fat streptozotocin and carefully controlled at room temperature. The type 2 diabetes mellitus Wistar rats were reproved with high glucose and high fat streptozotocin (STZ) Foot involvement in the establishment of type 2 diabetic foot rat model. The rats were randomly divided into three groups: metformin 0.140 g/kg group, red light therapy group combined with insulin treatment group, model group, blank control group (30 d after intragastric administration of rats), further observation of each group of rat wounds Healing rate, insulin, blood glucose and blood lipid and vascular endothelial activity factors such as laboratory changes. Results: The observation of red light therapy combined with insulin treatment group was the most obvious, the difference was statistically significant, significantly promoted wound healing in DF rats, increased healing rate, increased insulin sensitivity (NO) and nitric oxide synthase (NOS) were increased in the serum of rats. The insulin resistance and platelet aggregation rate of the DF model rats were significantly higher than those of the control group, and the insulin sensitivity index (ISI) , Blood glucose, blood lipid, blood viscosity and endothelin (ET) and other active factors were significantly reduced. Conclusion: (1) treatment of red light therapy can improve blood rheology, improve glucose and lipid metabolism, improve insulin sensitivity, Vascular endothelial cell activation and so on to improve the wound healing rate of DF wound in rats. (2) The treatment of red light therapy is effective, safe and high in clinical application.
