Integration of network pharmacology and bone marrow mesenchymal stem cells experimental research to reveal the molecular mechanisms for Hai Honghua medicinal liquor against osteoporosis

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.

Determination of Luzhou-flavor liquor ages by three-dimensional fluorescence spectroscopy combined with NMF

The determination of Luzhou-flavor liquor ages is carried out by three-dimensional fluorescence spectroscopy combined with non-negative matrix factorization(NMF). 37 samples of aged liquors with weighted ages of 15, 20 and 25 years were prepared by blending three Luzhou-flavor original base liquors with storage ages of 10, 20 and 30 years in different proportions. The fluorescence spectra of the samples were measured, and then factorized into basis matrix and coefficients matrix by multiplicative iterative NMF. The fluorescence spectra, reconstructed from the basis matrix, are similar to the original spectra. The coefficients matrix is taken as the input of support vector machine(SVM) to establish a prediction model for the determination of liquor ages. Compared with the principal component analysis, the prediction model based on SVM has a predicted accuracy better than 91.7%. This method can provide helps for the market supervision on the aged liquors.

Characterization of Formacell Lignin Derived from Black Liquor as a Potential Green Additive for Advanced Biocomposites

Black liquor is obtained as a by-product of the pulping process,which is used to convert biomass into pulp by removing lignin,hemicelluloses and other extractives from wood to free cellulose fibers.Lignin represents a major constituent in black liquor,with quantities varying from 20%to 30%,of which a very low share is used for manufacturing value-added products,while the rest is mainly burned for energy purposes,thus underestimating its great potential as a raw material.Therefore,it is essential to establish new isolation and extraction methods to increase lignin valorization in the development of bio-based chemicals.The aim of this research work was to determine the effect of KOH or ethanol concentration as an isolation agent on lignin yields and the chemical characteristics of lignin isolated from formacell black liquor of oil palm empty fruit bunch(OPEFB).Isolation of lignin was carried out using KOH with various concentrations ranging from 5%to 15%(w/v).Ethanol was also used to precipitate lignin from black liquor at concentrations varying from 5%to 30%(v/v).The results obtained showed that the addition of KOH solution at 12.5%and 15%concentrations resulted in better lignin yield and chemical properties of lignin,i.e.,pH values of 3.86 and 4.27,lignin yield of 12.78%and 14.95%,methoxyl content of 11.33%and 10.13%,and lignin equivalent weights of 476.25 and 427.03,respectively.Due to its phenolic structure and rich functional groups that are favorable for modifications,lignin has the potential to be used as a green additive in the development of advanced biocomposite products in various applications to replace current fossil fuel-based material,ranging from fillers,fire retardants,formaldehyde scavengers,carbon fibers,aerogels,and wood adhesives.

Research of the molecular mechanism of Hai Honghua medicinal liquor in the treatment of fracture based on network pharmacology combined with molecular docking

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.

从元代“汗酒”看中国蒸馏酒起源

元代的蒸馏酒虽有“汗酒”“烧酒”“重酿酒”等汉语名称,但一度流行的“阿剌吉酒”等音译名称,使得中国蒸馏酒起源成为颇具争议的国际性学术问题。本文在系统梳理史籍所载“汗酒”及其制备用具的基础上,结合考古发现的相关资料,通过“汗酒”名称和蒸馏器具渊源的探析,认为“汗酒”之名理应源自历史典故“汗出如浆”,而制备“汗酒”的酒铛实乃釜、甑等多件套甗式蒸馏器。尤其“酒铛”与古代蒸馏器实物的相互对应,有助于重新审视中国蒸馏酒、蒸馏器的起源及演化历程。
