[Method] Acute alcohol intoxication was induced by administering alcohol to mice. Three different doses （low, middle and high） of compound of traditional Chinese drugs were administered to mice before and after administering alcohol respectively to investigate the preventive and therapeutical effect of drugs on acute alcohol intox-ication through doing statistical analysis about drunk mice and their sleeping time. The concentration of malondialdehyde （MDA）, reduced glutathione （GSH） and triglyc-erides （TG） in liver was also determined to investigate the protective effect of drugs on liver. [Result] The efficacy of compound of traditional Chinese drugs on acute al-cohol intoxication was dose-dependent. High-dose administration decreased the number of drunk mice significantly compared with control group; middle- and high-dose administration reduced the sleeping time of drunk mice and the concentration of MDA and TG in liver tissue; three doses al increased the concentration of GSH. [Conclusion] The compound of Japanese raisintree fruit, lobed kudzuvine flower bud and lightyel ow sophora root had preventive and therapeutical effect on hangover, and it also had certain preventive and therapeutical effect on liver damage caused by alcohol.展开更多

In this work, the two kinds of traditional Chinese medicines collected from eleven areas of Dezhou, were analyzed by inductively couple plasma-mass spectrometry （ICP-MS） to compare the content and distribution of 14 kinds of rare earth elements （REEs）. The method was verified by analyzing GBW07605 certified reference material. The results showed that ICP-MS is an accurate, sensitive and reliable technique for determining REEs in traditional Chinese medicine. There were big differences in contents for REEs in Flos Sophorae and Fmctus Sophorae from different areas. The contents of total REEs in Flos Sophorae samples from different areas ranged from 1.0785 to 2.2659 μg/g, while those in Fmctus Sophorae from 0.6826 to 1.0527 ktg/g. The contents of total REEs in Flos Sophorae samples from different areas were obviously higher than those in Fmctus Sophorae of the same area and there was big difference between various Flos Sophorae samples. Interestingly, the higher the content of total REEs in Flos Sophorae samples, the lower the content of total REEs in Fmctus Sophorae samples of the same area. The plots of normalized element concentration versus atomic number showed some characteristic distribution trends. The distribution trend of light REEs （La-Gd） was relatively fiat except a positive Eu anomaly, however, that was steep and discrepant for heavy REEs （Tb-Lu）. The results could provide a valuable reference for understanding the relationship between the curative mechanism, pharmacology characteristics and their geological condition for the two traditional Chinese medicines investigated.展开更多

In order to find out the characteristic chemical constituents potentially leading to the unique medicinal properties claimed for each of the two closely related TCMs, an HPLC fingerprint method was developed for analyses of the alkaloid and flavonoid constituents of SFR and STR, respectively, which were further evaluated and compared through similarity calculation and hierarchical clustering analysis(HCA). The results from the present study showed that the alkaloid fingerprints of the two herbs were similar, with many components co-existing in both drugs and various batches of samples from different species being mixed together in the HCA dendrogram. However, their flavonoid constituents were totally different with specific fingerprints being yielded for each herb, and further HCA analysis showed that the tested samples could almost be clearly divided into two groups based on their origins of species. The results from the present study indicated that the flavonoid constituents could serve as the differentially diagnostic constituents of SFR and STR and might potentially attributed to their distinct therapeutic effects.展开更多

[ Meth- od] Using total DNA ERIC-PCR and 16S rRNA sequencing analysis method, a total of 48 endophytic bacteria were carried out genetic diversity and phylogenetic analysis. [Result] ERIC-PCR fingerprint map showed that 48 endophytic bacteria were divided into 6 ERIC groups and 2 strains with independent groups at Wat- son distance of 0.31. Representative strains were selected from each group to determine 16S rRNA gene for phylogenetic analysis, and the results showed that these strains belonged to Bacillus atrophaeus, Bacillus subtilis, Bacillus cereus, Bacillus megaterium, Bacillus pumilus and Serratia marcescens, respectively. [ Conclu- sion ] The genetic diversity of 48 strains of bacteria was obvious. Determination of 48 strains of bacteria on diversity and phylogenetic status could lay foundation for study on mechanism of F. oxysporum and V. dahliae, which could also provide new strain sources for biological control of diseases in cotton production.展开更多

文摘[Objectives]This study was conducted to screen lavandulyl flavonoids with anti-inflammatory activity from Sophora flavescens.[Methods]35 compounds were screened from traditional Chinese medicine S.flavescens using the nitric oxide(NO)anti-inflammatory activity model.[Results]Five components,8(xanthohumol),13(kurarinol),27(4-methoxysalicylic acid),28(b-resorcic acid)and 30(b-resorcic acid),exhibited significant anti-inflammatory activity,with IC 50 values of 5.99,4.76,6.96,3.41 and 5.22μM,respectively.Especially,8(xanthohumol)and 13(kurarinol)were typical lavandulyl flavonoids in S.flavescens,which were worth further exploration.Furthermore,UPLC-Q-Exactive and GNPS molecular networking technique were used for rapid analysis of lavandulyl flavonoids from S.flavescens.A total of 15 components were identified.[Conclusions]This work lays a theoretical foundation for further separation and analysis of lavandulyl flavonoids with anti-inflammatory activity from S.flavescens.
文摘This study aimed to investigate the mechanism of action of Sophora Flos(SF)in the treatment of hyperlipidemia(HLP)using network pharmacology and molecular docking methods,and to optimize the extraction process of the predicted active components.The STRING database was used for protein interaction analysis and PPI network construction via Cytoscape 3.9.1.Pymol was employed for docking and visualization.An extensive review of SF identifi ed 6 active ingredients,297 related objectives,84 disease objectives,and 57 total objectives.After protein interaction and topology analysis,18 core targets were identified.These included 146 gene function entries(P<0.05).Active compounds,mainly flavonoids,can modulate the expression of various proteins such as TNF,IL-6,IL-1β,PPARG,and TGFB1 to achieve therapeutic effects on HLP.The network pharmacology and molecular docking results suggested that the active fl avonoids component in SF may be related to the treatment of hyperlipidemia.Therefore,the orthogonal experiment method was used to optimize the extraction process of total fl avonoid from SF using ethanol refl ux extraction,based on a single factor experiment.The effects of refl ux time,solid-liquid ratio,ethanol concentration,and other factors on the extraction of total fl avonoid from SF were investigated.The optimum process conditions were refl ux time of 1.25 h,solid-liquid ratio of 1:15 g/mL and ethanol concentration of 60%.Using these conditions,the purity of total fl avonoid extracted from SF was 70.33±0.22%.

文摘Objective:This study used comprehensive bioinformatics analysis and network pharmacology analysis to investigate the potentially relevant mechanisms of Sophora flavescens against cervical squamous cell carcinoma.Methods:Consistently altered genes involved in cervical squamous cell cancerization were analyzed in the GEO database.The chemical ingredients and target genes of Sophora flavescens were explored using the TCMSP database.We obtained the potential therapeutic targets of Sophora flavescens by intersecting the above genesets and validated them in the GEPIA database.The interaction between Sophora flavescens and target genes was predicted by molecular docking.RT-qPCR was used to verify the changes of target genes in HeLa cells treated with Sophora flavescens.Single-gene GSEA functional analysis were performed to determine the molecular mechanisms.Results:Fifteen genes related to the transformation of cervical squamous cell carcinoma were identified,among which AR and ESR1 were confirmed as targets for kaempferol,wighteone,formononetin,and phaseolinon.These compounds are the active ingredients in Sophora flavescens.Low expressions of AR and ESR1 correlate with a poor prognosis,while Sophora flavescens treatment increases the expression of AR and ESR1 in HeLa.GSEA analysis showed that AR and ESR1 mainly participate in the epithelial-mesenchymal transition in cervical squamous cell carcinoma.Conclusion:Sophora flavescens exert anti-tumor effects by targeting AR and ESR1,which may regulate cancer metastasis.
文摘A lectin protein(SFL) with molecular weight about 32 kD which markedly agglutinated rabbit and human red blood cells was purified from the roots of Sophora flavescens Ait. This protein, and apparently inhibited the growth of Fusarium vasinfectum Atk., Gibberella saubinetii (Mont.) Sacc., and Piricularia oryzae Cav. A set of degenerate PCR primer was synthesized according to the N-terminal sequence of the purified protein. The full-length cDNA coding the lectin was cloned by RT-PCR and 5'-RACE and sequenced (GenBank AF285121). The deduced amino acid sequence indicates that a preprotein with 284 amino acid residues is firstly translated and then processed to a mature protein with 254 amino acids. A N-Glycosylation site is the Asn 182 residue.

文摘[Objective] We aimed to investigate the preventive and therapeutical effect of compound of traditional Chinese drugs （Japanese raisintree fruit, lobed kudzuvine flower bud and lightyel ow sophora root） on acute alcohol intoxication in mice. [Method] Acute alcohol intoxication was induced by administering alcohol to mice. Three different doses （low, middle and high） of compound of traditional Chinese drugs were administered to mice before and after administering alcohol respectively to investigate the preventive and therapeutical effect of drugs on acute alcohol intox-ication through doing statistical analysis about drunk mice and their sleeping time. The concentration of malondialdehyde （MDA）, reduced glutathione （GSH） and triglyc-erides （TG） in liver was also determined to investigate the protective effect of drugs on liver. [Result] The efficacy of compound of traditional Chinese drugs on acute al-cohol intoxication was dose-dependent. High-dose administration decreased the number of drunk mice significantly compared with control group; middle- and high-dose administration reduced the sleeping time of drunk mice and the concentration of MDA and TG in liver tissue; three doses al increased the concentration of GSH. [Conclusion] The compound of Japanese raisintree fruit, lobed kudzuvine flower bud and lightyel ow sophora root had preventive and therapeutical effect on hangover, and it also had certain preventive and therapeutical effect on liver damage caused by alcohol.

文摘Flos Sophorae and Fructus Sophorae are two kinds of traditional Chinese medicines. In this work, the two kinds of traditional Chinese medicines collected from eleven areas of Dezhou, were analyzed by inductively couple plasma-mass spectrometry （ICP-MS） to compare the content and distribution of 14 kinds of rare earth elements （REEs）. The method was verified by analyzing GBW07605 certified reference material. The results showed that ICP-MS is an accurate, sensitive and reliable technique for determining REEs in traditional Chinese medicine. There were big differences in contents for REEs in Flos Sophorae and Fmctus Sophorae from different areas. The contents of total REEs in Flos Sophorae samples from different areas ranged from 1.0785 to 2.2659 μg/g, while those in Fmctus Sophorae from 0.6826 to 1.0527 ktg/g. The contents of total REEs in Flos Sophorae samples from different areas were obviously higher than those in Fmctus Sophorae of the same area and there was big difference between various Flos Sophorae samples. Interestingly, the higher the content of total REEs in Flos Sophorae samples, the lower the content of total REEs in Fmctus Sophorae samples of the same area. The plots of normalized element concentration versus atomic number showed some characteristic distribution trends. The distribution trend of light REEs （La-Gd） was relatively fiat except a positive Eu anomaly, however, that was steep and discrepant for heavy REEs （Tb-Lu）. The results could provide a valuable reference for understanding the relationship between the curative mechanism, pharmacology characteristics and their geological condition for the two traditional Chinese medicines investigated.

文摘Sophorae Flavescentis Radix(Sophora flavescens Ait., SFR) and Sophorae Tonkinensis Radix et Rhizoma(S. tonkinensis Gapnep., STR) are two commonly used traditional Chinese medicines from Sophora(Leguminosae) plants, which are believed to possess similar bioactive components with entirely different clinical applications. In order to find out the characteristic chemical constituents potentially leading to the unique medicinal properties claimed for each of the two closely related TCMs, an HPLC fingerprint method was developed for analyses of the alkaloid and flavonoid constituents of SFR and STR, respectively, which were further evaluated and compared through similarity calculation and hierarchical clustering analysis(HCA). The results from the present study showed that the alkaloid fingerprints of the two herbs were similar, with many components co-existing in both drugs and various batches of samples from different species being mixed together in the HCA dendrogram. However, their flavonoid constituents were totally different with specific fingerprints being yielded for each herb, and further HCA analysis showed that the tested samples could almost be clearly divided into two groups based on their origins of species. The results from the present study indicated that the flavonoid constituents could serve as the differentially diagnostic constituents of SFR and STR and might potentially attributed to their distinct therapeutic effects.

文摘[ Objective ] The paper was to study and analyze the genetic diversity of 48 endophytic bacteria isolated from Sophora alopecuroide with strong antagonis- tic effect against Fusarium oxysporum and Verticillium dahliae, and carry out sequence measurement and phylogenetic analysis on 10 representative strains. [ Meth- od] Using total DNA ERIC-PCR and 16S rRNA sequencing analysis method, a total of 48 endophytic bacteria were carried out genetic diversity and phylogenetic analysis. [Result] ERIC-PCR fingerprint map showed that 48 endophytic bacteria were divided into 6 ERIC groups and 2 strains with independent groups at Wat- son distance of 0.31. Representative strains were selected from each group to determine 16S rRNA gene for phylogenetic analysis, and the results showed that these strains belonged to Bacillus atrophaeus, Bacillus subtilis, Bacillus cereus, Bacillus megaterium, Bacillus pumilus and Serratia marcescens, respectively. [ Conclu- sion ] The genetic diversity of 48 strains of bacteria was obvious. Determination of 48 strains of bacteria on diversity and phylogenetic status could lay foundation for study on mechanism of F. oxysporum and V. dahliae, which could also provide new strain sources for biological control of diseases in cotton production.
