Objective:To assess the antimicrobial,antibiofilm,anti-inflammatory,angiogenic,and wound healing activities of zinc nanoparticles(ZNPs)green synthesized using Ferula macrecolea extract.Methods:The green synthesis was conducted using the precipitation method.Then,the minimum inhibitory concentration(MIC),minimum bactericidal concentration(MBC),and minimum biofilm inhibition concentration 50%(MBIC50)of ZNPs against Staphylococcus aureus(S.aureus)and Pseudomonas aeruginosa(P.aeruginosa)were evaluated.The effects of ZNPs on the gene expressions of Staphylococcus spp.[intracellular adhesion A(icaA)and D(icaD)]and P.aeruginosa(rhlI and rhlR)were investigated using quantitative real-time PCR.In addition,the effects of ZNPs on wound healing,angiogenesis,and anti-inflammatory markers were assessed.Results:The green-synthesized ZNPs demonstrated significant antimicrobial efficacy against S.aureus and P.aeruginosa.The biofilm formation in S.aureus and P.aeruginosa was also inhibited by ZNPs with MBIC50 values of 3.30μg/mL and 2.08μg/mL,respectively.Additionally,ZNPs downregulated the expression of biofilm-related genes icaA,icaD,rhlI,and rhlR in the tested bacteria.They also demonstrated promising in vitro wound healing effects by promoting fibroblast cell proliferation and wound closure in a dose-dependent manner.A significant increase in the expression of HLA-G5 and VEGF-A genes as well as a marked decrease in the expression of NF-κB,IL-1β,and TNF-αgenes were observed in cells treated with ZNPs compared to the control group(P<0.05).Conclusions:ZNPs display promising antibacterial effects against S.aureus and P.aeruginosa and wound-healing effects by inhibiting biofilm formation,inducing angiogenesis,and reducing inflammation.However,further studies must be conducted to specify the accurate mechanisms of action and toxicity of ZNPs. 展开更多

Ferula spp. are traditional medicinal plants found in arid land. Large-scale excavation for extracting bioactive compounds from the plants in arid regions of Xinjiang over the last few years has, however, significandy decreased their distributions. Due to the urgent need for preservation of these plant resources, along with the need of searching for alternative source of the useful metabolites, it is important to screen the endophytic microbial resources associated with the plant Ferula sinkiangensis K. M. Shen. In the study, a total of 125 endophytic bacteria belonging to 3 phyla, 13 orders, 23 families, and 29 genera were isolated based on 16S rRNA gene sequencing data. Among the different isolates, three strains isolated from roots were potential novel species of the genera Porphyrobacter, Paracoccus and draycofatopsis. In this study, 79.4% and 57.1% of the total isolates were capable of producing indole-3-acetic acid (IAA) and siderophore, respectively. And, 40.6% of the strains inhibit the growth of fungal pathogen Afternaria alternata, 17.2% and 20.2% strains were positive for antagonism against Vertidllium dahlia 991 and V. dahlia 7, respectively. These results demonstrated that E sinkiangensis is a rich reservoir of endophytic bacterial resources with potential for production of biologically important functions such as plant growth-promoting factors. 展开更多

Background:Alzheimer’s disease(AD)is a neurodegenerative disease that primarily manifests as progressive memory loss and cognitive impairment.Traditional herbal medicines may be helpful in the discovery of new anti-AD drugs.Studies have shown that Ferula assafoetida has neuroprotective and memory-enhancing effects,which may be beneficial for the treatment of AD.However,the combination of active ingredients and their mechanisms remain unclear.Therefore,we aimed to identify potential active ingredients in F.assafoetida and their mechanisms of action against AD by using network pharmacology.Methods:In our study,an integrated network pharmacological approach,that included adsorption,distribution,metabolism and excretion screening,target identification,network construction,topological analysis,gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis,and molecular docking,was used to predict the pharmacological material basis and potential mechanisms through which these ingredients may treat and prevent AD.Results:The results indicated that 12 key active ingredients,obtained by topological analysis(including farnesiferol a,conferol,farnesiferol b,ferulic acid,etc.),may be the primary pharmacological components that may ameliorate AD.The 2 key significant pathways identified are the cholinergic synapse signaling pathway(critical targets include ACHE,CHRM1,CHRM2,MAPK1,PIK3CA,PIK3CB,PIK3CD,and PIK3CG)and the AD signaling pathway(critical targets include APP,BACE1,GSK3B,MAPK1,NCSTN,NOS1,PSEN1).These critical targets are closely related to the regulation of three typical pathological features of AD[central nervous system(CNS)cholinergic hypofunction,amyloid-β(Aβ)plaques,and hyperphosphorylated tau proteins].Finally,14 critical targets in the 2 key significant pathways were validated by molecular docking analysis.Conclusion:F.assafoetida may be effective for alleviating AD symptoms,through multi-component,multi-target,and multi-pathway synergistic effects,associated with the multiple pathogenesis hypotheses of AD.Our study may provide certain clues for the further development and utilization of this natural herbal medicine. 展开更多

OBJECTIVE Learning and memory impairment is one of the common sequelae of stroke patients,which is called"post-stroke dementia"and seriously affects the quality of life of the patients.For post-stroke dementia,there is still no effective clinical treatment.In the present study,we aim to investigate the effect of the active ingredient of Ferula sinkiangensis,AW09,on global cerebral ischemia-reperfusion mice.METHODS The bilateral common carotid artery occlusion(BCCAO)reperfusion model was used to investigate the protective effect of AW09 on cognitive dysfunction in mice with global cerebral ischemia reperfusion.Y-maze and Morris water maze were used to test the learning and memory ability of mice.RESULTS Y-maze test showed that AW09 treatment significantly increased the spontaneous alternation rate of BCCAO model animals and had no significant effect on the total number of arm entries.The results of Morris water maze showed that AW09 significantly reduced the escape latency of BCCAO mice during the training period.During the probe test phase,AW09 significantly increased the swimming time in target quadrant,distance in target quadrant and number of platform crossings and decreased the swimming time in the quadrant opposite the target quadrant of BCCAO mice.CONCLUSION AW09,the active ingredient of Ferula sinkiangensis,can improve working memory impairment and spatial memory impairment in animals with global cerebral ischemia-reperfusion,suggesting that AW09 has poten⁃tial therapeutic value for cognitive dysfunction caused by global cerebral ischemia. 展开更多
