Ancient and modern medication laws of aromatic Chinese medicines in treating angina pectoris based on data mining

Objective To explore ancient and modern medication laws of aromatic Chinese medicines in treating angina pectoris, and to provide new ideas for the clinical treatment.Methods With “angina pectoris” as the key word, ancient books prescriptions and Chinese patent medicines related to angina pectoris were collected from China National Knowledge Infrastructure(CNKI), Traditional Chinese Medicine Database System, Chinese Medicine Prescription Database, New National Proprietary Chinese Medicine(2 nd edition), and Chinese Pharmacopoeia(2020 edition) from January 1, 2015 to December 31, 2021. Core highfrequency aromatic Chinese medicines were defined, and their potential medication rules were analyzed and summarized. Microsoft Access 2010 was used for data management. Data analysis software, including Excel and IBM SPSS Modeler 18.0 were used for drug association rule analysis, and Cytoscape 3.7.2 for visual display.Results There were 67 ancient books prescriptions and 258 Chinese patent medicines containing aromatic Chinese medicines treating angina pectoris collected from relevant databases. In ancient books prescriptions, there were nine aromatic Chinese medicines with the frequency ≥10, and the most commonly used medicine was Danggui(Angelicae Sinensis Radix), followed by Chenpi(Citri Reticulatae Pericarpium). There were 33 aromatic Chinese medicines with the frequency ≥10 in Chinese patent medicines, and the most commonly used medicine was Danshen(Salviae Miltiorrhizae Radix et Rhizoma), followed by Chuanxiong(Chuanxiong Rhizoma) and Sanqi(Notoginseng Radix et Rhizoma). In ancient books prescriptions, the medicines mainly belonged to intenal-warming medicines, Qi-regulating medicines, and blood circulation promoting and blood stasis removing medicines.There were eight medicine pairs with confidence equal to 100% in ancient books prescriptions, the most frequently used pairs were Chuanxiong(Chuanxiong Rhizoma) +Danggui(Angelicae Sinensis Radix), and Xiangfu(Cyperi Rhizoma) + Chenpi(Citri Reticulatae Pericarpium). In Chinese patent medicines, the aromatic Chinese medicine Chuanxiong(Chuanxiong Rhizoma) could be combined with many other Chinese medicines, among which the Confidence and Support of Chuanxiong(Chuanxiong Rhizoma) + Danshen(Salviae Miltiorrhizae Radix et Rhizoma) were at a high level.Conclusion Aromatic Chinese medicines for the treatment of angina pectoris of coronary heart disease are mainly warm, and the flavors are mainly pungent, sweet, and bitter. They mainly access to the liver, gallbladder, and pericardium meridians. The treatment of angina pectoris of coronary heart disease mainly focuses on warming heart pulse, and promoting blood circulation and removing blood stasis.

Mechanism of Yinchenhao decoction in the treatment of jaundice based on network pharmacology

Objective:This study aimed to examine the mechanism of classic ancient prescription of Chinese medicine Yinchenhao decoction in treating jaundice based on network pharmacology.Method:An oral bioavailability of≥30%,a drug likeness of≥0.18,and literature studies were used to screen for Yinchen(Artemisiae scopariae herba),Zhizi(Gardeniae fructus),Dahuang(Rhei radix et rhizome)in the Chinese Medicine System Pharmacology Database and Analysis Platform.The active ingredient was introduced into the PubChem database to collect drug component targets and import into the Uniprot database for gene standardization.The target gene of Yinchen(Artemisiae scopariae herba)was screened via Human Gene Database(GeneCards).Then,use the Cytoscape 3.7.2 software was used for network visualization analysis,and the R3.6.1 software was used for gene ontology functional and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses.Results:We collected a total of 47 active constituents of classic ancient prescription of Chinese medicine Yinchenhao decoction,of which 17 were related to jaundice;189,9 targets of jaundice were screened,of which 41 were interdigitated with the targets of classic ancient prescription of Chinese medicine Yinchenhao decoction.Gene ontology functional enrichment analysis revealed 111 biological processes,14 cellular components,and 28 molecular functions,and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis showed 34 Kyoto Encyclopedia of Genes and Genomes pathways including hepatocellular carcinoma,PI3K-Akt signaling pathway,HIF-1 signaling pathway,prolactin signaling pathway,and non-alcoholic fatty liver disease.Conclusion:Based on the network pharmacology,the analysis of jaundice and classic ancient prescription of Chinese medicine Yinchenhao decoction provides a novel idea and direction for the study of classic ancient prescription of Chinese medicine Yinchenhao decoction in the treatment of jaundice.
