Advances in Research Methods of Pharmacodynamic Substances in Traditional Chinese Medicines and Their Application in the Teaching of Traditional Chinese Medicine Analysi

With the continuous progress of science and technology,the research methods of pharmacodynamic substances in traditional Chinese medicine are developing,and the application of these methods in teaching is becoming more and more extensive.By introducing these research methods into the classroom,teachers can help students to deeply understand the nature and mechanism of action of pharmacodynamic substances in traditional Chinese medicine,and improve their interest in and knowledge of traditional Chinese medicine.This paper introduces the definition of pharmacodynamic substances in traditional Chinese medicine,research methods,and their application in the teaching of traditional Chinese medicine analysis.

Pharmacodynamic Substance and Mechanism of Atractylodes macrocephala in Treating PD Based on LC-MS and Network Pharmacology Technology

[Objectives]The paper was to explore the pharmacodynamic substances and mechanism of Atractylodes macrocephala in treating primary dysmenorrhea(PD).[Methods]The components of A.macrocephala were qualitatively identified by ultra high performance liquid chromatography quadrupole-time of flight mass spectrometry(UPLC-MS)combined with analyst TF 1.7.1 and peakview 2.2 software with reference to internal databases and literatures.The chemical components of A.macrocephala and the target of PD were collected by using network pharmacological data.The common genes were analyzed by Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)of genes and genomes with the help of String database and Metascape platform,and the affinity between core molecules and key targets was verified.[Results]A total of 23 chemical components of A.macrocephala were identified,and 301 gene targets of chemical components of A.macrocephala,614 targets of PD,and 25 intersection targets were obtained.GO analysis results obtained 505 biological processes,11 cellular components,and 33 molecular functions.KEGG pathway analysis showed that it mainly involved TNF signaling pathway,IL-17 signaling pathway,estrogen receptor signaling pathway and arachidonic acid metabolism.The top 4 targets of PPI network centrality and the top 5 compounds of A.macrocephala-component-target-disease network centrality were selected for docking.The docking results showed that atractylenolide I,Selinar-4(15),7(11)-dien-8-one,and atractylenolide II had strong binding ability.[Conclusions]A.macrocephala may exert a curative effect on PD by targeting atractylenolide I,Selinar-4(15),7(11)-dien-8-one,and atractylenolide II on key targets such as TNF,IL6,IL1β,PTGS2 to regulate cellular TNF signaling pathway,IL-17 signaling pathway,estrogen receptor signaling pathway,and arachidonic acid metabolism.

Analysis on internal mechanism of zedoary turmeric in treatment of liver cancer based on pharmacodynamic substances and pharmacodynamic groups

Zedoary tumeric(Curcumae Rhizoma,Ezhu in Chinese)has a long history of application and has great potential in the treatment of liver cancer.The antiliver cancer effect of zedoary tumeric depends on the combined action of multiple pharmacodynamic substances.In order to clarify the specific mechanism of zedoary tumeric against liver cancer,this paper first analyzes the mechanism of its single pharmacodynamic substance against liver cancer,and then verifies the joint anti liver cancer mechanism of its“pharmacodynamic group”.By searching the research on the antihepatoma effect of active components of zedoary tumeric in recent years,we found that pharmacodynamic substances,including curcumol,zedoarondiol,curcumenol,curzerenone,curdione,curcumin,germacrone,β-elemene,can act on multi-target and multi-channel to play an antihepatoma role.For example,curcumin can regulate miR,GLO1,CD133,VEGF,YAP,LIN28B,GPR81,HCAR-1,P53 and PI3K/Akt/mTOR,HSP70/TLR4 and NF-κB.Wnt/TGF/EMT,Nrf2/Keap1,JAK/STAT and other pathways play an antihepatoma role.Network pharmacological analysis showed that the core targets of the“pharmacodynamic group”for anti-life cancer are AKT1,EGFR,MAPK8,etc,and the core pathways are neuroactive live receiver interaction,nitrogen metabolism,HIF-1 signaling pathway,etc.At the same time,by comparing and analyzing the relationship between the specific mechanisms of pharmacodynamic substance and“pharmacodynamic group”,it is found that they have great reference significance in target,pathway,biological function,determination of core pharmacodynamic components,formation of core target protein interaction,in-depth research of single pharmacodynamic substance,increasing curative effect and so on.By analyzing the internal mechanism of zedoary tumeric pharmacodynamic substance and“pharmacodynamic group”in the treatment of liver cancer,this paper intends to provide some ideas and references for the deeper pharmacological research of zedoary tumeric and the relationship between pharmacodynamic substance and“pharmacodynamic group”.
