Management of want to long-term situations from the outlying underneath the co-ordination involving nurses.
The species diversity of bacteria in the initial fermentation samples was also high, and Enterobacter was the dominant species. Enterobacter cloacae, Pediococcus pentosaceus and Cronobacter sakazakii became dominant bacterial species 17 h after fermentation commencement, while the species diversity was decreased. Our results will be a scientific basis for promoting the fermentation process of Massa Medicata Fermentata by using pure microbial cultures.Licorice has long been regarded as one of the most popular herbs, with a very wide clinical application range. Whether being used alone or as an ingredient in prescription, it has an important role which cannot be ignored. However, the efficacy and chemical constituents of licorice will change after honey-processing. Therefore, it is necessary to find quality markers before and after honey-processing to lay the foundation for a comprehensive evaluation of the differences between raw and processed licorice pieces. HPLC-DAD was employed to establish fingerprints of raw and processed licorice. Multivariate statistical analysis methods including principal component analysis(PCA) and orthogonal partial least squares discrimination analysis(OPLS-DA) were applied to screen out the differential components before and after processing of licorice. Based on network pharmacology, the targets and pathways corresponding to the differential components were analyzed with databases such as Swiss Target Prediction and Metascape, and the "component-target-pathway" diagram was constructed with Cytoscape 3.6.0 software to predict the potential quality markers. A total of 17 common peaks were successfully identified in the established fingerprint, and seven differential components were selected as potential quality markers(licoricesaponin G2, glycyrrhizic acid, liquiritigenin, liquiritin, isoliquiritin, liquiritin apioside and isoliquiritigenin). The HPLC fingerprint method proposed in this study was efficient and feasible. selleck chemical The above seven differential chemical components screened out as potential quality markers of licorice can help to improve and promote the overall quality. These researches offer more sufficient theoretical basis for scientific application of licorice and its corresponding products.In order to discuss the "entropy weight method" for weighting various indicators in the comprehensive evaluation of Angelicae Sinensis Radix slices(ASR), the quality of ASR was comprehensively evaluated by entropy weight-based gray systematic theory and cluster analysis. In this study, the contents of ferulic acid, volatile oil, polysaccharide, alcohol extract, water extract, moisture, total ash and acid-insoluble ash in 44 batches of ASR from different sources were determined. The entropy weight method was used for objective weighting. With relative correlation(r_i) as a measure, a multi-index comprehensive evaluation model was constructed for the quality of ASR. The results showed that the relative correlation value of 44 batches of ASR ranged from 0.301 9 to 0.662 9. There were certain differences in the quality of ASR from different sources. The ASR S1-S8, traceable and standardized in processing techno-logy, showed a high relative correlation degree and high quality ranking, indicating that the implementation of systemic management of the production chain of Chinese herbal pieces was beneficial to the quality control of ASR. The quality evaluation results of 44 batches of ASR were consistent with those of traditional geo-authentic habitats for ASR and the mainstream varieties of ASR on market, and basically consistent with the results of cluster analysis. This study suggests that the gray systematic theory based on the entropy weighting method can be used for the quality evaluation of ASR. The objective weighting of the entropy weight method improves the reliability of the gray correlation method and the scientificity of ASR quality evaluation.Based on the previous study of compound liquorice microemulsion, this paper aims to prepare the compound liquorice microemulsion gel and investigate its pharmacodynamics of chronic eczema. The type, dosage and adding method of gel matrix, and formula dosage of humectant were optimized by single factor method to obtain the formula and preparation technique of the gel. With glycyrrhizic acid, glycyrrhetin and oxymatrine used as evaluation indexes, the Franz diffusion cell method was adopted to monitor the in vitro release profile of the gel. Eczema model of delayed-type hypersensitivity in mice was chosen to detect the ear swelling rate, degree of inflammatory cell infiltration of ear pieces, and pathological changes of ear pieces, so as to investigate the therapeutic effect of the microemulsion gel. The preparation process of the compound liquorice microemulsion gel was stable. The release of glycyrrhizin and oxymatrine was most consistent with the Hixcon-Crowell kinetic model, while the release of glycyrrhizic acid was most consistent with the Ritger-Peppas kinetic model. The pharmacodynamics studies proved that compound liquorice microemulsion gel could significantly reduce the ear swelling rate in mice, with good anti-inflammatory effect as well as the ability to resist the pathological changes of chronic eczema and inhibit the infiltration of dermal inflammatory cells. Therefore, the preparation process of compound liquorice microemulsion gel is feasible, with stable drug release and a significant therapeutic effect on chronic eczema.Ginsenoside Rg_3 is widely used in clinical practice as an anti-tumor adjuvant drug, but its application is limited due to its poor oral absorption. In this study, we intended to construct a ginsenoside Rg_3 nanostructured lipid carrier modified by the pullulan(PUL-Rg_3-NLC) to improve the adhesion properties of ginsenoside Rg_3, promote the drug uptake and improve the anti-tumor efficacy. PUL-Rg_3-NLC was characterized by morphology, particle size and Zeta potential. In vivo adhesion characteristics were evaluated by oral gavage tests, and the results were verified from multiple perspectives in combination with in vitro uptake behavior and in vitro pharmacodynamics. The results showed that PUL-Rg_3-NLC, with a particle size of(102±1.89) nm, was characterized by gastric adhesion and could be retained in gastric tissues for a long time, and its uptake by BGC-823 cells was promoted mainly through the pathway mediated by the caveolin-mediated endocytosis. In vitro MTT, cell apoptosis, wound-healing assay and invasion assay all showed some anti-tumor effects.
