Study on mechanisms and molecular verification of Buyang Huanwu decoction in treating ischemic stroke from the perspective of cuproptosis

Background:Ischemic stroke(IS)is a global health issue and the current treatment options for IS are inadequate.Buyang Huanwu decoction(BHD)has demonstrated effectiveness in treating IS.However,the mechanisms by which BHD treats IS remain unclear,and no studies have been conducted to analyze these mechanisms from the perspective of Cuproptosis.In order to investigate the potential of BHD to intervene in IS through Cuproptosis,this study employed a systematic pharmacological approach and molecular docking verification.Methods:To investigate the mechanism of BHD in treating IS through Cuproptosis,relevant information on the structure,targets,and major biological functions and pathways of compounds related to BHD was collected from databases such as PubChem,PharmMapper,UniProt,and GeneCards.The results were then visualized using Cytoscape3.6.1,Ledock,and pymol software.Results:BHD is composed of 7 Chinese medicines,which contain 82 compounds,including 10 core compounds.These compounds are associated with 241 genes,of which 97 are common to BHD,IS,and Cuproptosis.The 97 common genes,including 10 core genes,are involved in biological processes such as proteolysis,regulation of apoptosis and cholesterol storage,as well as cellular components and molecular functions.The common genes among BHD,IS,and Cuproptosis,including 10 core genes,participate mainly in Kyoto Encyclopedia of Genes and Genomes pathways such as pathways in cancer,PI3K-Akt signaling pathway,and Estrogen signaling pathway.According to molecular docking results,linolenic acid showed good docking scores with 9 out of 10 core genes,except for SRC.13-hydroxy-9,11-octadecadienoic acid also demonstrated good docking scores with EGFR,MAPK14,and F2.Similarly,senkyunone also had good docking scores with EGFR,MAPK14,and F2,all of which had docking energy greater than−5 kcal.Conclusion:In this study,the potential of BHD for treating IS through Cuproptosis and its underlying mechanisms were explored and partially validated through molecular docking.However,due to the limitations of the systems pharmacology research method,further validation through cell experiments,animal experiments,and clinical trials may be necessary to confirm these findings.

Study on mechanism and molecular docking verification of Angelicae Sinensis Radix and Astragali Radix in treating ischemic stroke

Background:Traditional Chinese medicine(TCM)has been shown to be effective in treating ischemic stroke(IS),and the combination of Angelicae Sinensis Radix(ASR)and Astragali Radix(AR)is a core TCM prescription that is widely acknowledged for its efficacy in IS treatment.This study utilized network pharmacology methods to explore the molecular mechanisms underlying the therapeutic effects of Angelicae Sinensis Radix and Astragali Radix in IS treatment,with preliminary validation conducted through molecular docking.Methods:Information on the structure,targets,main biological functions,and pathways of the active components in Angelicae Sinensis Radix and Astragali Radix was collected using databases such as PubChem,PharmMapper,UniProt,and GeneCards.The results were visualized using software such as Cytoscape 3.6.1,Ledock,and pymol.Results:We retrieved 20 active components and 149 targets associated with the compatibility of Angelicae Sinensis Radix and Astragali Radix from various databases,and GeneCards database was used to search 3350 IS-related gene targets,including 78 key targets of Angelicae Sinensis Radix and Astragali Radix for the treatment of IS.Enrichment analysis of these 78 targets using gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)revealed the involvement of 48 GO terms in the treatment of IS,mainly in biological processes such as metabolism,biological regulation,and stress response.The composition of biological devices such as supercavitary membrane,cell fluid,and extracellular space was also involved.The biological functions mainly included protein binding,ion binding,hydrolytic enzyme activity,and others.The identified pathways were estrogen signaling pathway,mitogen-activated protein kinase(MAPK)signaling pathway,PI3K-AKT signaling pathway,RAP1 signaling pathway,P53 signaling pathway,PPAR signaling pathway,FOXO signaling pathway,RAS signaling pathway,prolactin signaling pathway,HIF-1 signaling pathway,and TNF signaling pathway.Molecular docking analysis showed that the 17 key active components of Angelicae Sinensis Radix and Astragali Radix had strong binding activity with 13 IS key targets.Conclusion:Through the application of network pharmacology methods,it was found that the use of Angelicae Sinensis Radix and Astragali Radix for treating ischemic stroke mainly targets the MAPK and PI3K-AKT signaling pathways,involving several crucial compounds and genes.Nevertheless,additional in vitro and in vivo studies are needed to verify these findings.

The effects of Buyang Huanwu decoction combined with Western medicine in diabetic foot treatment:a systematic review and meta-analysis

Objective:Systematically evaluate the effect of Buyang Huanwu decoction(BHD)combined with Western medicine(WM)in treating diabetic foot(DF).Methods:Randomized controlled trials that examined the effects of BHD on DF were collected from various databases,including CBM,PubMed,EMBASE,Web of Science,CNKI,Wanfang,and Weipu.Two researchers evaluated the quality of the literature and extracted relevant data,which was then analyzed using RevMan 5.3 for meta-analysis.The analysis was carried out in accordance with the 2020 PRISMA checklist.Results:The study analyzed 19 articles involving 1284 patients.According to the meta-analysis,BHD combined with WM improved clinical efficacy and reduced traditional Chinese medicine syndrome scores,glycosylated hemoglobin,and fibrinogen levels in DF patients.Although the BHD combined with WM showed a trend towards reducing wound area,the difference was not significant.Additionally,the incidence of adverse reactions did not show a significant decrease with BHD combined with WM.Conclusion:The findings of the study indicated that the use of BHD combined with WM yielded better therapeutic outcomes than WM alone,supporting the recommendation of using BHD with WM for DF treatment.This approach is suggested for further clinical application and promotion.
