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

The complex permittivity of baijiu varies with frequency,and dielectric spectroscopy has been used to evaluate the quality.To simplify the analysis and reduce the number of the parameters,a dielectric relaxation model is often used to fit the permittivity data.However,existing fitting methods such as the least squares and particle swarm optimization methods are often computationally complex and require preset initial values.Therefore,a simpler calculation method of the relaxation parameters considering the geometric characteristics of the permittivity spectrum is proposed.It is based on the relationship between the Cole-Cole relaxation parameters and the Cole-Cole diagram,which is fitted by a geometric method.First,the concepts of the Cole-Cole parameters and the diagram are introduced,and then the process of obtaining the parameters from the complex permittivity measurement data is explained.Taking baijiu with 56%alcohol by volume(ABV)as an example,the fitting is better than the least squares method and similar to the particle swarm optimization.This method is then used for the parameter fitting of baijiu with ABV of 42-52%,and the average error is less than 1%,demonstrating its wider applicability.Finally,a prediction model is used for baijiu with 53%ABV,and the error is only 1.51%.Hence,the method can be applied to the measurement of ABV of baijiu. 展开更多

This study investigated the aroma-active compounds and compared the differences of three different grades of sesame-flavor Baijiu by headspace solid-phase microextraction(HS-SPME)coupled with gas chromatography-olfactometry-mass spectrometry(GC-O-MS).A total of 54 aroma-active compounds were detected.Principal component analysis showed that JZ1,JZ2,and JZ3 were well separated from each other.JZ1 as the premium-grade Baijiu had the highest aroma intensities,concentrations.According to aroma intensities and concentrations,dimethyl trisulfide,butanoic acid,phenylacetaldehyde,2-furylmethanethiol,ethyl hexanoate,2,6-dimethylpyrazine,etc.could be potentially applied as volatile makers to distinguish the three different grades of sesame-flavor Baijiu as their significant difference(P<0.05)in three Baijiu samples.Roasted aroma had the significant difference(P<0.05)in three sample base on aroma profiles.Meanwhile,2-furylmethanethiol,2,6-dimethylpyrazine were related to the roasted aroma,they may be had a significant contribution to the differences of three different grades of sesame-flavor Baijiu.This study has provided a comprehensive understanding of the differences of three different grades of sesame-flavor Baijiu. 展开更多

Excessive alcohol consumption(≥15 drinks per week)causes chronic diseases and multiple other health conditions.Nevertheless,alcohol beverages have been used as a vital medicine ingredient in various cultures since ancient times.A wealth of epidemiological and experimental research has shown that light-moderate alcohol consumption,regardless of beverage type,is associated with reducing cardiovascular incidence and mortality rate.Due to the disparities in raw materials,fermentation techniques,production environment,etc.,alcoholic beverages tend to possess different non-ethanol component profiles,thus resulting in varying degrees of health effects.Furthermore,bioactive compounds in alcohol are continuously discovered as well as the mechanisms underlying their cardioprotective contributions at a molecular level.This article elucidates the epidemiology of moderate alcohol consumption and various cardiovascular conditions,along with the limitations and controversies of current studies.In addition,protective effects and putative mechanisms of both ethanol and non-ethanol components of wine,beer,and Chinese Baijiu,the three most representative alcoholic beverages worldwide,are to be evaluated within the context of a rational drinking pattern. 展开更多

Qingke(highland barley)Baijiu is a special Chinese Baijiu which is mainly produced from Qinghai-Tibet Plateau.Since the pine board is used as the bottom of the fermentation pit,we deduced that the terpenoids and norisoprenoids in pine board might be introduced into Qingke Baijiu.Thus,the terpenoids and norisoprenoids in Qingke Baijiu were investigated by headspace solid phase microextraction(HS-SPME)combined with comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry(GC×GC-TOFMS).The results showed thatγ-terpinene(0.70-530.72μg/L),α-phellandrene(0.34-256.66μg/L),longicyclene(0-38.55μg/L),α-pinene(1.21-35.54μg/L)and limonene(0.93-23.69μg/L)were the top 5 terpenoids/norisoprenoids in Qingke Baijiu.Pulegone was detected and reported for the first time in Baijiu,and the concentrations in Qingke Baijiu were 0.78μg/L(fresh)and 3.90μg/L(7 years old).According to the principal component analysis(PCA)plot,young,aged,and retail Qingke Baijiu could be differentiated clearly.Fold change(FC)and t-tests analysis indicated thatβ-pinene,γ-terpinene,andα-selinene were the most different terpenoids/norisoprenoids between young and aged Qingke Baijiu,and longifolene was the most different terpenoids/norisoprenoids between base and retail Qingke Baijiu.The terpenoids and norisoprenoids,such as(E)-β-ionone,isoborneol andβ-cyclocitral,could be potential markers indicating the ageing process of Qingke Baijiu. 展开更多

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. 展开更多

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“... 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。 展开更多
