Objective To explore the differential expression and mechanisms of bone formation-related genes in osteoporosis(OP)leveraging bioinformatics and machine learning methodologies;and to predict the active ingredients of targeted traditional Chinese medicine(TCM)herbs.Methods The Gene Expression Omnibus(GEO)and GeneCards databases were employed to conduct a comprehensive screening of genes and disease-associated loci pertinent to the pathogenesis of OP.The R package was utilized as the analytical tool for the identification of differentially expressed genes.Least absolute shrinkage and selection operator(LASSO)logis-tic regression analysis and support vector machine-recursive feature elimination(SVM-RFE)algorithm were employed in defining the genetic signature specific to OP.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses for the selected pivotal genes were conducted.The cell-type identification by estimating rela-tive subsets of RNA transcripts(CIBERSORT)algorithm was leveraged to examine the infiltra-tion patterns of immune cells;with Spearman’s rank correlation analysis utilized to assess the relationship between the expression levels of the genes and the presence of immune cells.Coremine Medical Database was used to screen out potential TCM herbs for the treatment of OP.Comparative Toxicogenomics Database(CTD)was employed for forecasting the TCM ac-tive ingredients targeting the key genes.AutoDock Vina 1.2.2 and GROMACS 2020 softwares were employed to conclude analysis results;facilitating the exploration of binding affinity and conformational dynamics between the TCM active ingredients and their biological targets.Results Ten genes were identified by intersecting the results from the GEO and GeneCards databases.Through the application of LASSO regression and SVM-RFE algorithm;four piv-otal genes were selected:coat protein(CP);kallikrein 3(KLK3);polymeraseγ(POLG);and transient receptor potential vanilloid 4(TRPV4).GO and KEGG pathway enrichment analy-ses revealed that these trait genes were predominantly engaged in the regulation of defense response activation;maintenance of cellular metal ion balance;and the production of chemokine ligand 5.These genes were notably associated with signaling pathways such as ferroptosis;porphyrin metabolism;and base excision repair.Immune infiltration analysis showed that key genes were highly correlated with immune cells.Macrophage M0;M1;M2;and resting dendritic cell were significantly different between groups;and there were signifi-cant differences between different groups(P<0.05).The interaction counts of resveratrol;curcumin;and quercetin with KLK3 were 7;3;and 2;respectively.It shows that the interac-tions of resveratrol;curcumin;and quercetin with KLK3 were substantial.Molecular docking and molecular dynamics simulations further confirmed the robust binding affinity of these bioactive compounds to the target genes.Conclusion Pivotal genes including CP;KLK3;POLG;and TRPV4;exhibited commendable significant prognostic value;and played a crucial role in the diagnostic assessment of OP.Resveratrol;curcumin;and quercetin;natural compounds found in TCM;showed promise in their potential to effectively modulate the bone-forming gene KLK3.This study provides a sci-entific basis for the interpretation of the pathogenesis of OP and the development of clinical drugs. 展开更多

[Objectives]To establish the chromatographic fingerprint of Gancao Qinlian Extracts(GQE)and reveal the possible material basis of the anti-inflammatory effect of GQE by the correlation analysis between the fingerprint chromatographic peaks of different components of GQE and its anti-inflammatory activity.[Methods]Ultra-performance liquid chromatography(UPLC)was used to detect the different ingredients of GQE to establish its chromatographic fingerprint and analyze the differences among the three medicine components;LPS stimulated RAW264.7 cells to construct an inflammatory cell model.The NO secretion of cells was detected by the Griess method.ELISA was used to detect the changes in TNF-αand IL-10 contents.RT-qPCR tested the mRNA expression levels of TNF-αand IL-10.Grey relational analysis was carried out by combining fingerprint chromatographic peak data and anti-inflammatory activity data.[Results]The GQE fingerprint was established,34 fingerprint characteristic peaks were calibrated,and 33 related chromatographic peaks were screened out.The corresponding chromatographic peaks in the three components were obtained,and the content of the components was calculated;the anti-inflammatory results showed that the content of NO,TNF-α,and the expression of TNF-αmRNA in the high and medium-dose groups of GQE were significantly lower than those in the blank group(P<0.01).The NO content and TNF-αmRNA expression in the high-dose group of GQE I was considerably lower than those in the blank group(P<0.01).The secretion of NO,TNF-α,and the expression of TNF-αmRNA in the high,medium,and low dose groups of GQE II were significantly lower than those in the blank group(P<0.01);the results of grey relational analysis showed that the correlation degree of the three components was GQE II>GQE>GQE I,and the characteristic fingerprint peaks 12,15,22,23,28,31,33 may be closely related to the anti-inflammatory effect.[Conclusions]The best component of the anti-inflammatory effect in GQE is water-soluble component,and its main components are flavonoids and alkaloids.These components can alleviate cellular inflammatory damage by inhibiting the excessive secretion of NO and reducing the expression of TNF-αmRNA. 展开更多

The assumptions and models for solubility modelling or prediction in systems using nonpolar solvents, or water and complex triterpene and other active pharmaceutical ingredients as solutes aren't well studied. Furthermore, the assumptions concerning heat capacity effects(negligibility, experimental values or approximations) are explored, using non-polar solvents(benzene), or water as reference solvents, for systems with solute melting points in the range of 306–528 K and molecular weights in the range of 90–442 g/mol. New empirical estimation methods for the Δ_(fus)C_(pi) of APIs are presented which correlate the solute molecular masses and van der Waals surface areas with Δ_(fus)C_(pi). Separate empirical parameters were required for oxygenated and non-oxygenated solutes. Subsequently, the predictive capabilities of the various approaches to solubility modelling for complex pharmaceuticals,for which data is limited, are analysed. The solute selection is based on a principal component analysis, considering molecular weights, fusion temperatures, and solubilities in a non-polar solvent, alcohol, and water, where data was available. New NRTL-SAC parameters were determined for selected steroids, by regression. The original UNIFAC, modified UNIFAC(Dortmund), COSMO-RS(OL), and COSMO-SAC activity coefficient predictions are then conducted, based on the availability of group constants and sigma profiles. These are undertaken to assess the predictive capabilities of these models when each assumption concerning heat capacity is employed. The predictive qualities of the models are assessed, based on the mean square deviation and provide guidelines for model selection, and assumptions concerning phase equilibrium, when designing solid–liquid separators for the pharmaceutical industry on process simulation software. The most suitable assumption regarding Δ_(fus)C_(pi) was found to be system specific, with modified UNIFAC(Dortmund) performing well in benzene as a solvent system, while original UNIFAC performs better in aqueous systems.Original UNIFAC outperforms other predictive models tested in the triterpene/steroidal systems,with no significant influence from the assumptions regarding Δ_(fus)C_(pi). 展开更多

The antidepressive effect of Xiaoyaosan is doubtless by researches while the potential antidepressive ac- tive ingredients and their mechanisms remain unclear. In order to explain the antidepressive effect of Xiaoyaosan, all of the recent reports were sought out on the current situation of the antidepressive monomer compositions of Xi- aoyaosan and their mechanism. By exploring the relationship between the effects and the active ingredients, the mechanism and the active ingredients, the antidepressive active ingredients such as quercetin, isorhamnetin, isoliquiritigenin, saikosaponinA, saikosaponinD, glycyrrhiz- kaempferol, liquiritin, isoliquiritin, liquiritigenin, inate, paeoniflorin, albiflorin, ferulic acid, curcumin and their mechanism of antidepressive such as regulating the monoamine neurotransmitter systems, regulating the neuroendocrine system, affecting the neural plasticity and neu- affecting the cytokines level, anti-oxidative stress were rotrophic, affecting the cellular and molecular mechanisms , summarized. By the overview in the level of monomer rather than formulae, we uncovered the antidepressive mech- anism of Xiaoyaosan and further confirmed that Xiaoyaosan, as a classic antidepressive Chinese prescription, had many characteristics, such as multi-level , multi-channel, multi-target and so on . 展开更多

Multiple emulsions are of great therapeutic interest especially in the administration of medicines which can be inactivated by digestive enzymes;moreover the researches of formulation not being often easy, a control of the different phases physicochemical parameters would be of great interest in rapid formulations and at low cost. When formulating emulsions, the preliminary tests, also known as formulation tests, constitute a step which can be long and expensive because of the quantity of reagents that can be used. A rigorous methodology could thus be of great interest, which is at the aim of our study which consists of evaluating the physico-chemical parameters of different phases used to make thus multiple emulsions. In our study, physico-chemical parameters such as conductivity, pH, density, viscosity, and surface tension have been studied by direct measurement using equipment and also by means of suitable mounting. The results showed that the pH and the surface tension have an important role in the prediction of the stability of emulsions, these latter must be of the same order of magnitude. For all phases conductivity does not have too much interest apart from helping to determine the type of the emulsion. 展开更多

Metasurfaces have opened the door to next-generation optical devices due to their ability to dramatically modulate electromagnetic waves at will using periodically arranged nanostructures.However,metasurfaces typically have static optical responses with fixed geometries of nanostructures,which poses challenges for implementing transition to technology by replacing conventional optical components.To solve this problem,liquid crystals(LCs)have been actively employed for designing tunable metasurfaces using their adjustable birefringent in real time.Here,we review recent studies on LCpowered tunable metasurfaces,which are categorized as wavefront tuning and spectral tuning.Compared to numerous reviews on tunable metasurfaces,this review intensively explores recent development of LC-integrated metasurfaces.At the end of this review,we briefly introduce the latest research trends on LC-powered metasurfaces and suggest further directions for improving LCs.We hope that this review will accelerate the development of new and innovative LC-powered devices. 展开更多
