Background:Oxidative stress is one of the key elements in the progression of non-alcoholic fatty liver disease(NAFLD),and Yiqi Tongluo capsule(YTC)have a variety of physiological activities which include antioxidant.The purpose of this investigation was to discover the potential mechanisms of YTC ameliorates NAFLD.Methods:In this investigation,a high-fat diet(HFD)was adopted to establish a NAFLD mouse model.Liver samples were stained for oil red O and hematoxylin and eosin staining.The levels of total cholesterol(TC),triglyceride(TG),malondialdehyde(MDA),and superoxide dismutase(SOD)in the tissues were also detected.Network pharmacology was analyzed to filter out the key ingredients and targets of effect of YTC for the therapy of NAFLD.Subsequently,free fatty acids(FFA)was applied to induce Aml12 cells for in vitro experiments,and the cell samples were stained with oil red O and assayed for TC,TG,MDA,and SOD contents.At last,the Western blot technique was used to illuminate the pathway by which YTC plays a protective role against NAFLD.Results:Histopathological results demonstrated that YTC ameliorated tissue damage in the HFD-induced mouse model.At the same time,it also reduced the contents of TC,TG,MDA and increased the expression of SOD in the liver tissue of NAFLD mouse model.All of these findings demonstrate that YTC can play a role in the treatment of NAFLD by ameliorating oxidative stress.Network analysis of YTC ameliorates NAFLD mainly by modulating the PI3K-Akt signaling pathway.Follow-up in vitro experiments revealed that FFA caused lipid accumulation in Aml12 cells,which was dramatically reduced by YTC.Meanwhile,YTC could remarkably reduce the FFA-induced elevation of TC,TG,and MDA contents,and reverse the FFA-induced reduction of SOD contents.Western blot was verified for the PI3K-Akt signaling pathway.It was found that FFA could remarkably decrease the expression of p-PI3K,p-Akt,and p-GSK-3βproteins,which could be significantly increased after YTC treatment.Conclusions:The combination of network analysis prediction and experimental verification was used to identify the therapeutic effect of YTC on NAFLD.The protective effect was achieved by YTC through upregulation of PI3K-Akt-GSK-3βpathway. 展开更多

Background:Hai Honghua medicinal liquor(HHML)formula has been used in clinical practice for a long time,mainly for the treatment of freshly closed fractures,to promote osteogenesis,to increase bone mass,and thus to promote fracture healing.However,the underlying mechanisms of HHML in the treatment of osteoporosis(OP)are still unclear.Methods:Firstly,Traditional Chinese Medicines Systems Pharmacology Database and Analysis Platform and The Encyclopedia of Traditional Chinese Medicine were used to screen the targets of the active compounds of HHML.At the same time,OP targets were identified through GeneCards,Online Mendelian Inheritance in Man,DisGeNET,Therapeutic Target Database,Comparative Toxicogenomics Database and Human Phenotype Ontology databases.Next,protein-protein interaction and pathway networks were constructed for compound-disease common targets,and core targets and compounds were screened for molecular docking.Furthermore,rat bone marrow mesenchymal stem cells were extracted as model cells,and the osteogenic effects of HHML were verified via in vitro experiments.Results:Total of 343 common targets of HHML-OP and the top 10 target proteins in the protein-protein interaction network are TP53,AKT1,STAT3,HSP90AA1,ESR1,TNF,IL6,MAPK1,MAPK3 and MAPK8.Enrichment analysis yielded that the key molecular pathway was the PI3K/Akt signaling pathway.Molecular docking analysis showed that baicalein,erysodienone and naringenin docked with the target proteins AKT1,STAT3 and TP53,respectively,with low binding energy and high affinity.In addition,In vitro experiments demonstrated that HHML promoted the proliferation of bone marrow mesenchymal stem cells;compared with the control group,HHML-treated cells showed enhanced alkaline phosphatase staining,promoted the expression of OCN,RUNX2,BSP,and COL1 mRNAs as well as the expression of PI3K and AKT phosphorylated proteins.Secondly,the expression of target proteins revealed that HHML promoted the phosphorylation of STAT3 protein and inhibited the expression of P53.Conclusions:Our study investigated that HHML treatment with OP promotes bone formation possibly through activation of the PI3K/Akt signaling pathway and may involve STAT3 and TP53 target interactions. 展开更多

Background:Hai Honghua medicinal liquor(HHML),a famous hospital formula composed of 19 traditional Chinese medicines,has been successfully applied in treating soft tissue injury,fresh closed fracture,limb dysfunction after fracture healing,shoulder,neck and leg pain,knee joint pain and other clinical multiple diseases for 30 years in clinical.However,research on the material basis of HHML for the treatment of fracture healing-related disorders is still in a gap.Therefore,it is particularly important to explore the active ingredients,core targets and potential pharmacological mechanisms of HHML to promote fracture healing.Methods:We screened the core active components of each traditional Chinese medicine in formula and its action targets through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform and Encyclopedia of Traditional Chinese Medicine database.The fracture related targets were retrieved from several different public databases,including GeneCards,Online Mendelian Inheritance in Man,DisGeNET and Therapeutic Target Database.Bioinformatics analysis to obtain key bioactive components,underlying targets and signaling pathways,containing the Venn diagram of the intersection with components and diseases gene targets,protein–protein interaction,as well as the Gene Ontology and the Kyoto Encyclopedia of Genes and Genomes analysis,and finally molecular docking.Results:A total of 249 bioactive ingredients of HHML and 325 HHML-fracture-related targets were screened.The network analysis revealed that quercetin,luteolin,kaempferol,Licochalcone A,naringenin and 8-Isopentenyl-kaempferol may be potential candidate agents.Multiple targets are involved including TP53,MAPK3,STAT3,AKT1,MAPK1,HSP90AA1,ESR1 and PIK3CA may be closely linked targets.PI3K-AKT signaling pathway may play a significant role of HHML in treatment of fracture.What’s more,molecular docking suggested that 8-isopentenyl kaempferol,glycyrrhiza chalcone A,and naringenin bound to AKT1,PIK3CA,and ESR1,respectively,exhibiting lower energy and more stable characteristics.Conclusions:The findings indicate the potential active ingredients,target proteins and molecular mechanisms of HHML for the treatment of fractures to provide the exact idea for the next research on the mechanism of action of HHML formula for fracture treatment. 展开更多
