Zhou and its relatives. [Method] The morphological characteristics of the mature seed-like fruits of Salvia shandongensis and its three congeners, S. miltiorrhiza, S. miltiorrhiza f. alba and S. bowleyana, were comparatively observed using both optical microscope and scanning electron microscope. [Result] The results showed that there were distinct differences in the shape, size and exine sculpture of the seed-like fruits of the four Danshen congeners： the seed-like fruits of S. shandongensis that were elliptical and had areolate sculpture with subquadrangular convex meshes as well as densely filamentous transverse lines were easy to be distinguished from those of S. miltiorrhiza Bge., which were broadly elliptical and had reticulate sculpture with subquadrate concave meshes. The seed-like fruits of S. bowleyana were fusiform and their ektexine had reticulate sculpture with polygonal meshes, which were slightly convex at the center, which are obviously different from those of S. shandongensis. [Conclusion] This study first accumulates data of the seed-like fruits of S. shandongensis, which provides important bases for establishing its taxonomical status and studying its germplasm. The morphological characteristics and reticulate sculpture on ektexine of the seed-like fruits S. miltiorrhiza Bge. are consistent with the previous report. The results in this study not only provide references for uncovering the genetic relationships between S. shandongensis and S. miltiorrhiza Bge., as well as the interspecific classification and identification. In addition, this study also provides new scientific proofs for the identification of Danshen species and their introduction and cultivation, genetics and breeding.展开更多

In the present study, a Shimadzu CLC-ODS column(150 mm x 6 mm, 5 μm) was utilized and 0.5% formic acid (A) and acetonitrile (B) were used forgradient elution at a total flow rate of 0.8 mL· min^(-1). All calibration curves showed goodlinear regression ( r > 0.999) within test ranges. Extraction was conducted by refluxing methanol(10 mL) with dried herb (0.5 g) for 1.0 h.The assay was simple, convenient and reproducible. Theproposed method was successfully applied to the determination of nine major constituents in thirteenSalvia. species and the results showed that the contents of Salvia components vary in differentspecies and origin. Tanshinone was hardly detected in S. yunnanensis and S. prionitis, thereforethey are not suitable for clinical use as Danshen.展开更多

Five components(10 μmol/L)were shown to inhibit superoxide anion generation by xanthine─xanthine oxidase system. It was also demonstrated that six components( 100 μmol/L) prevented H_2O_2─induced hemolysis and MDA fonnation in mouse erythrocytes.The effects of Sal A, Sal B, Sal C and Ros A were dose dependent. In Langendorff rat heart, pretreatment with Sal A 20μmol/L significantly prevented MDA production induced by 30 min reoxygenation after 45 min anoxia.The results indicated that there were also other potent antioxidant componentts in Salvia milliorrhiza besides Dphl and Pal. The protection of Sal A against myocardial anoxiareoxygenation inury may be mainly ascribed to its oxygen free radical scavenging activity.展开更多

文摘Salvia miltiorrhiza(Danshen)is a traditional Chinese herb that is commonly known for its cardiovascular and hepatoprotective benefits.Recent studies have confirmed that Danshen and its bioactive components can influence gut microbial homeostasis,thereby affecting Helicobacter pylori(HP)colonization in the human stomach.HP is a bacterial pathogen associated with various gastrointestinal diseases.Current HP treatments mainly involve antibiotics and proton pump inhibitors.However,their efficacy is strongly compromised by the rapid emergence of antibiotic resistance in HP and genetic heterogeneity among patients.The interaction between Danshen and gut microbial status provides a novel perspective for HP treatment.Understanding the medical properties of Danshen in altering gut microbiota and eliminating HP,as well as the underlying mechanisms,is important for improving human gastrointestinal healthcare.This review investigates the interaction between Danshen and gut microbiota and its impact on HP infection using databases including Web of Science,PubMed,and Google Scholar.We explored the unconventional intersection between Danshen,gut microbiota,and HP infection,shedding light on their intricate interplay and potential therapeutic implications.A comprehensive understanding of this interaction provides valuable insights into developing novel therapeutic strategies that target the gut microbiota to mitigate HP-associated gastrointestinal disorders.
文摘Objective:This study aims to investigate the potential molecular mechanism of Salvia miltiorrhiza in treating benign prostatic hyperplasia(BPH)based on network pharmacology.Methods:Active components of Salvia miltiorrhiza were screened via the TCMSP database,and their potential targets were predicted using Swiss Target Prediction.BPH-related targets were obtained from Gene Cards and OMIM databases.Common targets between the herb and BPH were used to con-struct a protein-protein interaction(PPI)network via STRING and visualized using Cytoscape.Core targets were identifi ed,and Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were conducted(P≤0.01).Results:A total of 57 active components and 818 targets of Salvia miltiorrhiza were identifi ed.Intersection analysis yielded 458 potential targets associated with BPH.PPI network analysis revealed core targets including SRC,PIK3R1,and PIK3CA.GO enrichment analysis indicated that the targets were primarily associated with biological processes(BP)such as calcium ion homeostasis,cellular components(CC)including focal adhesions,and molecular functions(MF)such as tyrosine kinase activity.KEGG pathway analysis indicated that Salvia miltiorrhiza may exert therapeutic effects through pathways including MAPK,PI3K-Akt,and calcium signaling(P≤0.01).Conclusion:Salvia miltiorrhiza may regulate BPH through a multi-component,multi-target,and multi-pathway network,providing a theoretical basis for its clinical application.

文摘[Objective] This study aimed to compare and analyse the morphological characteristics of the seed-like fruits between Salvia shandongensis J. X. Li et F. Q. Zhou and its relatives. [Method] The morphological characteristics of the mature seed-like fruits of Salvia shandongensis and its three congeners, S. miltiorrhiza, S. miltiorrhiza f. alba and S. bowleyana, were comparatively observed using both optical microscope and scanning electron microscope. [Result] The results showed that there were distinct differences in the shape, size and exine sculpture of the seed-like fruits of the four Danshen congeners： the seed-like fruits of S. shandongensis that were elliptical and had areolate sculpture with subquadrangular convex meshes as well as densely filamentous transverse lines were easy to be distinguished from those of S. miltiorrhiza Bge., which were broadly elliptical and had reticulate sculpture with subquadrate concave meshes. The seed-like fruits of S. bowleyana were fusiform and their ektexine had reticulate sculpture with polygonal meshes, which were slightly convex at the center, which are obviously different from those of S. shandongensis. [Conclusion] This study first accumulates data of the seed-like fruits of S. shandongensis, which provides important bases for establishing its taxonomical status and studying its germplasm. The morphological characteristics and reticulate sculpture on ektexine of the seed-like fruits S. miltiorrhiza Bge. are consistent with the previous report. The results in this study not only provide references for uncovering the genetic relationships between S. shandongensis and S. miltiorrhiza Bge., as well as the interspecific classification and identification. In addition, this study also provides new scientific proofs for the identification of Danshen species and their introduction and cultivation, genetics and breeding.

文摘To elucidate the mechanism underlying the therapeutic impact of Astragalus-Danshen in chronic glomerulonephritis(CGN),a comprehensive exploration was conducted utilizing network pharmacology.The TCMSP database was employed to aggregate the chemical constituents and targets associated with Astragalus and Danshen.Simultaneously,disease targets specific to CGN were sourced from the Genecards database.The convergence of these datasets yielded a set of intersection genes,representing potential targets for CGN treatment through Astragalus-Danshen formulations.Subsequently,protein interaction networks and“chemical composition-target”networks were meticulously constructed.Core targets were subjected to GO and KEGG enrichment analyses.The investigation revealed a total of 240 targets corresponding to 20 and 65 chemical components of Astragalus and Danshen,respectively.From this pool,86 potential targets associated with CGN treatment were discerned,ultimately identifying 29 core targets.Noteworthy among these were TNF,JUN,TP53,IL1B,RELA,MMP9,CASP3,IL10,MAPK14,MYC,and TGFB1.KEGG enrichment analysis illuminated pathways pertinent to CGN,encompassing the IL-17 signaling pathway,TNF signaling pathway,and the AGE-RAGE signaling pathway in diabetic complications.In summary,Astragalus-Danshen exhibited a potential anti-inflammatory and renoprotective effect on CGN,particularly through modulating the IL-17 signaling pathway,TNF signaling pathway,and AGE-RAGE signaling pathway in diabetic complications,involving key regulators such as TNF,JUN,TP53,IL1B,MAPK14,and others.

文摘Root exudates serve as crucial mediators for information exchange between plants and soil,and are an important evolutionary mechanism for plants’adaptation to environmental changes.In this study,15 different abiotic stress models were established using various stress factors,including drought(D),high temperature(T),nitrogen deficiency(N),phosphorus deficiency(P),and their combinations.We investigated their effects on the seedling growth of Salvia miltiorrhiza Bunge and the activities of Solid-Urease(S-UE),Solid-Nitrite Reductase(S-NiR),Solid-Nitrate Reductase(S-NR),Solid-Phosphotransferase(S-PT),and Solid-Catalase(S-CAT),as well as the contents of polysaccharides in the culture medium.The results showed that the growth of S.miltiorrhiza was inhibited under 15 stress conditions.Among them,13 stress conditions increased the root-shoot ratio.These 15 stress conditions significantly reduced the activity of S-NR,two combinations significantly improved the activity of S-NIR,they were synergistic stresses of high temperature and nitrogen deficiency(TN),and synergistic stresses of drought and nitrogen deficiency(DN)(p<0.05).The activity of S-UE was significantly improved under N,D,T,synergistic stresses of drought and high temperature(DT),DN,synergistic stresses of drought and phosphorus deficiency(DP),and synergistic stresses of high temperature,nitrogen,and phosphorus deficiency(TNP)stress conditions(p<0.05).Most stress combinations reduced the activity of S-PT,but D and T significantly improved it.(p<0.05).The N,DN,and TN stress conditions significantly reduced S-CAT activity.The P,DT,and synergistic stresses of drought,high temperature,and phosphorus deficiency(DTP)significantly decreased the total polysaccharide content of the soil(p<0.05).The research suggested that abiotic stress hindered the growth of S.miltiorrhiza and altered the behavior of root secretion.Roots regulated the secretion of several substances in response to various abiotic stresses,including soil nitrogen cycle enzymes,phosphorus transport-related enzymes,and antioxidant enzymes.In conclusion,plants regulate the utilization of rhizosphere substances in response to abiotic stresses by modulating the exudation of soil enzymes and polysaccharides by the root system.At the same time,soil carbon sequestration was affected by the adverse environment,which restricted the input of organic matter into the soil.
文摘BACKGROUND Diabetic peripheral neuropathy(DPN)is a debilitating complication of diabetes mellitus with limited available treatment options.Radix Salviae,a traditional Chinese herb,has shown promise in treating DPN,but its therapeutic mech-anisms have not been systematically investigated.AIM Radix Salviae(Danshen in pinin),a traditional Chinese medicine(TCM),is widely used to treat DPN in China.However,the mechanism through which Radix Salviae treats DPN remains unclear.Therefore,we aimed to explore the mechanism of action of Radix Salviae against DPN using network pharmacology.METHODS The active ingredients and target genes of Radix Salviae were screened using the TCM pharmacology database and analysis platform.The genes associated with DPN were obtained from the Gene Cards and OMIM databases,a drug-com-position-target-disease network was constructed,and a protein–protein inter-action network was subsequently constructed to screen the main targets.Gene Ontology(GO)functional annotation and pathway enrichment analysis were performed via the Kyoto Encyclopedia of Genes and Genomes(KEGG)using Bioconductor.RESULTS A total of 56 effective components,108 targets and 4581 DPN-related target genes of Radix Salviae were screened.Intervention with Radix Salviae for DPN mainly involved 81 target genes.The top 30 major targets were selected for enrichment analysis of GO and KEGG pathways.CONCLUSION These results suggested that Radix Salviae could treat DPN by regulating the AGE-RAGE signaling pathway and the PI3K-Akt signaling pathway.Therefore,Danshen may affect DPN by regulating inflammation and apoptosis.

文摘A method of gradient-elution HPLC with UV detection was developed for theanalysis of nine major constituents of Salvia species, a commonly used TCM herb, namely danshensu,protocatechuic acid, protocatechualdehyde, salviano-lic acid B, methyltanshinone, dihydrotanshinone,cryptotanshinone, tanshinoneⅠand tanshinoneⅡ_A. In the present study, a Shimadzu CLC-ODS column(150 mm x 6 mm, 5 μm) was utilized and 0.5% formic acid (A) and acetonitrile (B) were used forgradient elution at a total flow rate of 0.8 mL· min^(-1). All calibration curves showed goodlinear regression ( r > 0.999) within test ranges. Extraction was conducted by refluxing methanol(10 mL) with dried herb (0.5 g) for 1.0 h.The assay was simple, convenient and reproducible. Theproposed method was successfully applied to the determination of nine major constituents in thirteenSalvia. species and the results showed that the contents of Salvia components vary in differentspecies and origin. Tanshinone was hardly detected in S. yunnanensis and S. prionitis, thereforethey are not suitable for clinical use as Danshen.
文摘The effects of water─soluble components isolated from Salvia miltiorrhiza on oxygen free radical prodction and lipid peroxidation were estimated. Five components(10 μmol/L)were shown to inhibit superoxide anion generation by xanthine─xanthine oxidase system. It was also demonstrated that six components( 100 μmol/L) prevented H_2O_2─induced hemolysis and MDA fonnation in mouse erythrocytes.The effects of Sal A, Sal B, Sal C and Ros A were dose dependent. In Langendorff rat heart, pretreatment with Sal A 20μmol/L significantly prevented MDA production induced by 30 min reoxygenation after 45 min anoxia.The results indicated that there were also other potent antioxidant componentts in Salvia milliorrhiza besides Dphl and Pal. The protection of Sal A against myocardial anoxiareoxygenation inury may be mainly ascribed to its oxygen free radical scavenging activity.

文摘Cadmium(Cd)has seriously affected the quality of traditional Chinese medicinal material Salvia miltiorrhiza in recent years,threatening human health.The physiological and metabolic profiles of S.miltiorrhiza in response to Cd stress have been revealed in previous studies.However,transcriptional and post-transcriptional regulation in response to different degrees of Cd(0,25,50,and 100 mg/kg)stress in S.miltiorrhiza remains unclear.Here,transcriptome atlas in S.miltiorrhiza under different degrees of Cd Stress was unveiled using RNA sequencing(RNA-seq).These results showed that the profiles of gene expression were different in the response to Cd treatment.Defense response-related biological processes were involved in differentially expressed genes(DEGs).In total,1966 genes were identified as transcription factors(TFs)with seven expressed trends.Retained intron(RI)was the major phenomenon.Targeted genes of intron splicing factors were identified via weighted gene co-expression network analysis(WGCNA).All of these indicated that transcriptional and post-transcriptional regulations were involved in response to Cd stress in S.miltiorrhiza.Our study will provide the most comprehensive resource for studying heavy metals in traditional Chinese medicine plants.
