[Abstract]:Objective: to sort out professor Wu Huanlin's inheritance and development of the Deng Tietao five Zang related theory in the treatment of coronary heart disease, and the method of data mining to analyze the clinical medication rule of Professor Wu Huanlin in the treatment of coronary heart disease under the guidance of the related theory of five zang organs. The effect and mechanism of antiplatelet aggregation and anti arterial thrombosis are discussed, and the basis for clinical use of drugs is provided. Methods: the study of academic thought mainly through the literature analysis and the method of following up with the doctor, combing the origin and development of coronary heart disease related to the five zang organs related treatment. The application of data mining technology to the clinical drug use law analysis According to the inclusion and exclusion criteria, the medical cases of Professor Wu Huanlin were collected, standardized and structured to form a standardized database, and the traditional Chinese Medicine Inheritance auxiliary platform software was used to make four statistics, five statistics, statistics, drug model analysis based on association rules and rules analysis based on association rules, based on improved mutual information. Analysis of the degree of association of the drugs, based on the combination analysis of drug extraction with complex system entropy clustering, based on the combination analysis of the unsupervised entropy hierarchical clustering. 66 SPF grade SD rats were randomly divided into 6 groups, which were blank group, high dose group, middle dose group, low dose group, positive control group, 12 rats in each group, 6 rats in model group and 7 intervention. 7 The whole group of the model group, half of the high, middle and low dose group, half of the positive control group were given the carotid artery thrombosis with iron trichloride external application, half of the blank groups were given the sham operation control, the blood flow of the carotid artery, the pathological section of paraffin and HE staining, the effect of the anti arterial thrombosis in the experimental drugs were analyzed; the rest of the animals were given 7 intervention. After the abdominal aorta, the blood was taken from the abdominal aorta, the platelet aggregation rate was detected, the ELISA detection of platelet cAMP, the PI3K-Akt and the PKC-Erk pathway protein Western blot were detected, and the mechanism of antiplatelet antiplatelet agents was analyzed. Results: the five organs related theory developed on the basis of the five line theory, which refers to the five internal organs and five systems with the five viscera as the center. Between the five systems and the body, and the nature, and society mutual influence and restriction. On the basis of inheritance and development, the five organs related to the treatment of coronary heart disease can be divided into three stages: the related stage of the heart and the liver, the related stage of the heart and the spleen, the related stage of the heart and the lung and the kidney, and pay attention to the main viscera and clinical features of each stage. At the same stage, there were different pathogenesis, different treatment rules and prescriptions. Study on the rule of drug use: a total of 1044 prescriptions and 191 flavors were included. The drugs used in more than 100 times were 41 flavors; the drugs were mainly divided into spleen, stomach, lung, liver, heart and kidney in turn: warm, flat, cold, cold, and heat, and the five flavors of drugs were classified in turn. Gump, bitterness, symplectic, light, salty, acid. Based on the association rules of the drug model analysis, the support was set to 550, the drug model was set to 45, involving 7 flavors; the support was set to 500, and the support was set to 450, involving 9 drugs. The drug rule analysis, the support degree of 550, the confidence degree 0.90 of the drug rules 101; confidence greater than 0.9. 8 drug rule 38. Based on the correlation analysis of improved mutual information method, the correlation degree is set to 8, the penalty degree is set to 2, and the correlation coefficient is more than 0.03 to 24. The combination analysis of drug extraction based on the entropy clustering of complex system is obtained, and 20 core combinations of the 3-4 flavors are obtained. Through the unsupervised entropy hierarchical clustering algorithm, the results are obtained. The potential new side combined 10.Omin carotid artery base blood flow, and there was no difference between each group (P0.05). 15min carotid artery blood flow monitoring showed that the high dose group increased the blood flow of the carotid artery (P0.05) in the high dose group, and the 25min carotid artery blood flow monitoring showed that the high dose group increased the blood flow of the carotid artery (P0.01) in the high dose group (P0.01) and paraffin wax. The results of slicing and HE staining showed that the experimental drug was dose-dependent to reduce the volume of thrombus in the carotid artery. In the experimental drug, the high dose group reduced the platelet aggregation rate (P0.05, P0.01). Further studies found that the content of cAMP in the high dose group was higher than that in the ADP group (P0.01). The results of protein immunoblotting showed that the experiment was carried out. The high dose group could reduce the expression of PI3Kp110 beta in the platelet (P0.05). The high dose group reduced the expression of p-Akt/t- Akt in the platelets (P0.01). Compared with the ADP group, the low, middle and high dose groups of the experimental drugs could not change the p-pkc expression in the platelets (P0.05). The high dose group of the experimental drugs could reduce the p-erk/t- ER in the platelets. K expression (P0.05). Conclusion: the theory of five zang organs related to the theory of five elements, based on the limitations of the five line theory and the needs of clinical practice, the five Zang related theories gestation and birth, Professor Wu Huanlin on the five Zang related treatment of coronary heart disease on the basis of the original refinement and development, gradually become a more mature theory. On the premise of a large proportion of the spleen stage cases, the drug is based on Invigorating Qi to invigorate the spleen, eliminating phlegm dampness and activating blood type drugs. The drugs are mainly treated with spleen, stomach, lung, liver, heart and kidney; the four gases are mainly warm and flat; five flavors are Gump, bitter and symplectic. In the form of machine dialogue, the rule of drug use can be obtained to guide the clinical. Experimental study: experimental drugs have the effect of anti SD rat carotid thrombosis, inhibit platelet activation, reduce platelet aggregation rate, its mechanism may be up regulation of cAMP expression and inhibit the activation of PI3K-Akt-erk signaling pathway.
