[Abstract]:Objective: To study the blood glucose and blood lipid of the diabetic rats by means of the experimental study of the model of diabetic rats by intraperitoneal injection of the streptozoin (STZ) and the treatment of diabetic rats with the effects of invigorating qi, nourishing yin and promoting blood circulation. The effects of endothelial lipase (EL) and the morphology of the endothelial tissue of the thoracic aorta in rats were studied, and the therapeutic effect and possible mechanism of the recipe on the large-vessel lesions of the model-type diabetic rats were studied. Methods: 50 rats were randomly divided into 5 groups: normal group (N) 6, model group (M), and traditional Chinese medicine group (qi-nourishing and yin-nourishing and blood-activating group). Z), western medicine group (simvastatin group, X), traditional Chinese medicine + western medicine group (Yiqi Yangyin Huoxue Fang + Simvastatin group, ZX) 1 1. Reference to the relevant literature, M, Z, X, ZX group, rats with a concentration of 1% of a chain-cometacin (STZ) citrate buffer (citric acid buffer at a concentration of 0. 1mmol/ L, pH 4.5) were used as one-time abdominal cavity at 60mg/ kg body weight The blood glucose of the rat tail vein was measured by intraperitoneal injection of the corresponding volume of 1% citric acid-sodium citrate solution, and the blood glucose was measured in the tail vein of the rat after 72h. If the blood sugar in the rat was more than 16.7mmol/ L and the amount of water and urine increased, the model was made. In the group of ZX group, the traditional Chinese medicine with the same amount of qi, nourishing yin, promoting blood circulation and promoting blood circulation was given in the morning of ZX group, and the same amount of simvastatin was given in the afternoon. In the group of Gavage, N and M, the volume of the corresponding Chinese traditional Chinese medicine was given intragastric administration, once a day, and a total of 1 was given by intragastric administration. 2 weeks. After the end of the stomach, the rats were fasted, and the water for 12h and 2% sodium pentobarbital was injected into the abdominal cavity by 20mg/ kg body weight. The blood was decapitated, and the plasma glucose, total cholesterol, low density lipoprotein cholesterol and high-density lipoprotein cholesterol were detected. Sterol. The thoracic aorta 1-2cm was taken as a specimen in a sterile operation, and was fixed in 4% paraformaldehyde solution. The section line HE staining was made to observe the changes of the vascular endothelial tissue. The enzyme-linked immunosorbent assay was used to detect the serum endothelial lipase (EL). Level. Results: 1 The general situation of the rats in each group was in the course of the experiment, and the rats in the N group were full of spirit and free of activity. The diet, drinking water and urine volume were all normal. The rats in the M group had the symptoms of listlessness, obvious polydipsia, polyphagia, polyuria, gradually reduced body weight, yellow and yellow hair, slow response and the like, and it was in accordance with the clinical

"three or one" of diabetes. The characteristics of s" . The performance of each treatment group in rats in between that normal group and the model group. there was a limb activity in the rat In group M, ZX group. There were 2 deaths and 1 death in the Z group. In group 2, the blood glucose level of the rats was higher than that of the normal group (P <0.05). The blood sugar changes between the group X and the M group were statistically significant (P0.05). There was no significant difference in blood glucose between Z and ZX groups (P <0.05), and the change of blood glucose between Z and ZX groups was not significant (P0.05). No significant, no statistical significance (P0.05). Total cholesterol (TC) and high-density lipoprotein cholesterol (HDL) in each group of rats (1) The level of low-density lipoprotein cholesterol (LDL) was higher than that in the treatment group. Compared with the normal group, the difference was statistically significant (P0.05); the difference between the group Z and the M group was not significant and there was no statistical significance (P0.05); the TC between the X group and the ZX group and the M group was lower and the difference was statistically significant (P0.05); and the difference between the X group and the ZX group was statistically significant (P0.05). There was no significant difference in the TC (P0.05). There was no significant difference in LDL in the M group and in the treatment group (P <0.05), and the difference between the group Z and the M group was not significant (P0.05), and the X group and the ZX group and the M group were not significant (P0.05). There was a significant difference between the group and the group (P <0.05), and the ZX group was the same as that of the group. In group X, LDL decreased and the difference was statistically significant (P0.05). The difference was significant between the treatment group and the control group (P <0.05), and the difference between the treatment group and the M group was significantly higher and the difference was statistically significant (P <0.05). (P0.05); between the three treatment groups There are significant changes in the HDL, and the difference is in series. The results showed that after HE staining, the endothelial cells of group N were clear in texture, normal in shape, uniform in color, flat in the endothelial cells of the thoracic aorta and smooth in the intima. in flat, that middle film is a parallel phase The smooth muscle cells (SMC) and the elastic plate were arranged in the middle membrane of the M group. The inner membrane of the rat thoracic aorta of the M group had the localized thickening and the local uplift and the smooth muscle cells of the inner membrane of the inner membrane were found to be hyperplastic and arranged, and the proliferation of the smooth muscle cells was increased. The elastic plates at the green smooth muscle cells are arranged irregularly, in a wave shape, and even visible elastic plates are broken The changes of the tissue morphology of the thoracic aortic endothelial cells in the treatment group were more than that of the model. The expression of serum endothelial lipase (EL) was detected by enzyme-linked immunosorbent assay (ELISA) in each group, and the levels of EL in all treatment groups were increased. Compared with the normal group, the difference was significant (P <0.05), and the difference between the treatment group and the M group was significantly lower (P <0.05), and the difference was significant (P 0. 0 5) There was a significant difference between the three treatment groups, and the difference was significant (P0. Conclusion: 1. The qi-tonifying and yin-nourishing blood-activating agent can improve the general condition of the diabetic rats, reduce the blood sugar and regulate the lipid metabolism. The qi-tonifying and yin-nourishing blood-activating agent can be used for invigorating qi and nourishing yin and promoting blood circulation. The pathological changes of the vascular endothelial tissue in the thoracic aorta of the diabetic rats have improved, and the effect of the treatment of the diabetic macrovascular endothelial diseases can be provided. The treatment scheme can be provided for clinical treatment.
