[Abstract]:Diabetic foot is a systemic disease. The longer the duration of foot ulcers, the more likely the ulcer complicated with infection, the higher the risk of amputation. Therefore, how to effectively promote the healing of diabetic foot ulcers is a vital link in the treatment. This paper, guided by the theory of collateral disease, suggests that the disease is caused by spleen loss, two injuries of Qi Yin, and blood stasis. The main disease position is collaterals and collaterals, the main diseases are collaterals and blood stasis, the main diseases are collaterals, muscles, and the "collaterals are used" as the general treatment principle. The prescription of Yiqi nourishing yin and clearing heat and collaterals is founded according to the principle of this method. This paper evaluates the therapeutic effect of the prescription on the treatment of diabetic foot by theoretical carding and experimental research, and discusses its possible mechanism of action and promotes it. Objective: To observe the therapeutic effect of Yiqi Yangyin qinluo Tongluo Recipe on diabetic foot mice induced by type 2 diabetes, explore the possible pathogenesis of diabetic foot, and reveal the mechanism of the treatment of diabetic foot by clearing Qi and nourishing yin and clearing heat and dredging collaterals, providing new ideas for prevention and treatment of the disease and providing a scientific basis for clinical popularization. 70 SPF grade C57BL/6J male mice were selected and 10 were randomly selected as normal control group. The other mice were fed with high glucose and high fat diet combined with Streptozotocin (STZ) (120 mg/kg) and ligated the lower limbs of the lower limbs. The mice model of type 2 diabetes mellitus with diabetic foot was constructed successfully. The digital table was divided into 6 groups: model control group, metformin combined with cilostazol group (Western medicine control group), Tongsai Mai group, Yiqi Yangyin qinluo Tongluo prescription high, middle, low dose group. Using biochemistry, optical microscope, immunohistochemistry, three dimensional quantitative stereology and other detection methods and methods, dynamic observation of Qi Nourishing Yin and nourishing yin. The general state, weight, fasting blood glucose (Fasting blood glucose, FBG), wound size, inflammatory factor, vascular endothelial function, angiogenesis index, oxidative stress index, Fasting insulin (FINS), empty abdominal C- peptide (Fasting C-Peptide, FC-P), insulin-like growth factor -1. Owth factor 1, IGF-1), the effect of islet cell morphology and function. Results: (1) the high dose group of Yiqi Yangyin clearing heat Tongluo recipe, the weight of the mice in the western medicine control group was increased (P0.05), the increase trend was close to the normal control group. (2) the western medicine control group, Tongsai Mai tablet group, Yiqi Yangyin clearing heat dredging collaterals prescription high, middle, low dosage. The volume group continued to reduce FBG, obviously lower than the model control group (P0.001), and low, middle, high dose groups of blood sugar decreased in turn. (3) western medicine control group, Yiqi Yangyin qinluo Tongluo prescription high, middle, low dose group after treatment, the ulcer area is significantly smaller than the model group, the number of scab days obviously shortened, lower limb ulcers redness and swelling gradually Regression, claudication and tactile allergy were improved (P0.001, P0.01 or P0.05). (4) the concentration of the hypersensitive C reactive protein (High sensitive C reaction protein, hs-CRP) in the middle and low dose groups was significantly lower than that in the middle and low dose groups. The content of thromboxane B2 (Thromboxane B2, TXB2) and endothelin -1 (Endothelin-1, ET-1) decreased significantly (P0.001, or P0.01), and the content of 6- ketone prostaglandin F-1 alpha (6-Keto-PGF-1 alpha, alpha) in high dose group increased significantly. (5) the higher dose group was compared with the model control group. The content of othelial growth factor, VEGF) was significantly increased (P0.05). (6) the western medicine control group, Tongsai Mai tablet group, Yiqi Yangyin Tongluo Fang Gao, the medium dose group of mice pancreatic superoxide dismutase (Superoxide dismutase, SOD), and the content of reduced glutathione (Glutathione, GSH) was significantly higher than the model control group (P0.05, P0.01, or VEGF), malondialdehyde The content of (Malondialdehyde, MDA) was significantly lower than that of the model control group (P0.01). (7) compared with the model control group, the FC-P content in the rest of the treatment groups was obviously increased (P0.05 or P0.001) except the low dose group of Yiqi Yangyin clearing heat Tongluo recipe. The high dose of Tongsai Mai tablet group and the high dose of Yiqi Yangyin clearing heat dredging collaterals were compared with that of the group of Yiqi Yangyin qinluo Tongluo Fang Group FC-P content increased (P0.01, or P0.001). (8) compared with the model control group, the IGF-1 content in the high dose group of the western medicine control group was significantly higher (P0.05). The FINS level in the western medicine treatment group was significantly higher than that of the model control group (P0.001). The western medicine control group was compared with the low dose group of Yiqi Yangyin Tongluo prescription, the western medicine control group, the Yiqi Yangyin clearing heat and the heat clearing. The FINS content in the middle dose group increased (P0.05, or P0.001). (9) compared with the model control group, the insulin resistance index (Homeostasis model assessment of insulin resistance index, HOMA-IR) decreased significantly (P0.001). (10) the hematoxylin eosin staining, immunohistochemical staining, and three-dimensional stereopsis. The study showed that Yiqi Yangyin Qingre Tongluo recipe could postpone pancreatic islet atrophy, promote islet structure and repair of islet beta cells, alleviate the pathological damage of islet cells, regulate the state of the mice, improve the symptoms of diabetic foot, and accelerate the healing of foot ulcer. (1) the level of blood sugar can be adjusted by the prescription of nourishing yin and nourishing yin and clearing heat and dredging collaterals. Inhibiting the continuous decline of body weight, regulating vascular endothelial function, inhibiting the release of inflammatory factors, improving the state of tissue ischemia and hypoxia, thus promoting the growth of the granulation tissue and shortening the healing time of the ulcer, especially in the high dose group, the comprehensive improvement is most obvious. (2) the high dose of Supplementing Qi and nourishing yin and clearing heat and dredging collaterals can regulate the serum V EGF concentration, activating cell proliferation and growth of granulation tissue, promoting angiogenesis, accelerating healing of foot ulcers, enhancing pancreatic antioxidant stress and preventing or postponing pancreatic function damage. (3) high dose of nourishing yin and clearing heat and dredging collaterals can reduce insulin resistance, increase insulin sensitivity, promote islet structure and islet beta cell repair. The improvement of insulin resistance and islet beta cell apoptosis and dysfunction were improved, and the improvement of high dose group was better than that in the middle and low dose group. (4) high dose of Yiqi nourishing yin and clearing heat and dredging collaterals prescription reduced sugar, reduced the area of ulcer, reduced the effect of insulin resistance better than the Tongsai tablet, improved the function of vascular endothelium, reduced the level of inflammatory factors and reduced the level of inflammatory factors. The volume atrophy of the small islets of the pancreas and the improvement of the overall state of the mice are superior to those of the western medicine. Tongsai Tongmai Recipe. It can not only enhance the antioxidant stress ability of the diabetic foot mice, reduce the insulin resistance, but also relieve the injury of the ulcerative oxidizing inflammation, improve the microenvironment of the sores, and make a common use of diabetes. The therapeutic effect of foot disease is better than that of high dosage of Supplementing Qi, nourishing Yin, clearing heat and dredging collaterals.
