ABSTRACT
Objective:To explore the rules of acupoint sticking therapy based on data mining technology for the treatment of angina pectoris of coronary heart diseases, and to provide a reference for guiding acupoint selection and rational use of Chinese medicine.Methods:To search for the clinical research literature of acupoints for the treatment of angina pectoris of coronary heart diseases from China Academic Journal Database (Wanfang Data), China National Knowledge Resources Database (CNKI), China biomedical literature service system (SinoMed) and Chinese science and technology journal database (Chongqing VIP) dated from January 31, 2020. Using Microsoft Excel 2016, SPSS Statistics 21.0, and SPSS Modeler 14.2 statistical software as tools to conduct association analysis and cluster analysis on those acupoints and Chinese medicine.Results:A total of 102 acupoints application prescriptions were included, involving 38 acupoints. The top 5 frequently used acupoints were Danzhong (RN17), Neiguan (PC6), Xinshu (BL15), Zusanli (ST36), and Zhiyang (DU9). The top 5 acupuncture were Neiguan (PC6)- Sanyinjiao (SP6), Xinshu (BL15)- Geshu (BL17), Danzhong (RN17)- Geshu (BL17), Danzhong (RN17)- Jueyinshu (BL14), Danzhong (RN17)- Geshu (BL17) and Xinshu (BL15). There are 102 prescriptions of applied medicines with 88 kinds of Chinese medicine. The top 5 frequently used Chinese medicines were Chuanxiong Rhizoma, Borneolum Syntheticum, Salviae Miltiorrhizae Radix et Rhizoma, Olibanum, Santali Albi Lignum, the top three drug pairs were Chuanxiong Rhizoma- Cinnamomi Cortex, Allii Macrostemonis Bulbus- Trichosanthis Fructus, Olibanum- Myrrha. Conclusion:The commonly used single points to treat angina pectoris of coronary heart disease are Danzhong, and usually combined with Neiguan and Xinshu, and the acupoints along the Urinary Bladder Meridian of Foot- Taiyang are used frequently; the Chinese medicines are mainly used for activating blood circulation, genenrally reflects the therapeutic principle of removing blood stasis, dredging collaterals and relieving pain.
ABSTRACT
Objective To study the changes of hippocampal caspase-3 and PSD-95 expression levels in the mice exposed to ketamine 30 mg/(kg·d)for three months. Methods Forty C57BL/6 mice were randomly divided into two groups,and the chronic ketamine addiction model was established by giving mice a three month course of daily intraperitoneal injections of ketamine. Immunohistochemical study and Western blot-ting were applied to observe the expression of caspase-3 and PSD-95 protein. Results There were more expression of caspase-3 and less of PSD-95 in ketamine group as detected by immuohistochemistry. Western blotting results showed caspase-3 active fragment level significantly increased com-pared to saline group,but PSD-95 protein level was decreased. Conclusion The increased level of caspase-3 protein and reduced expression of PSD-95 are observed after long-term ketamine administration. These findings may provide an evidence for the neurotoxicity in mouse hippocampus of chronic ketamine addition as a recreational drug.
