METHODS: QHD is composed of 11 herbs, which was prepared by a fixed Pharmacy and concentrated into clear paste. High-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry(HPLC-QTOF/MS) was used to detect the phytochemical profile of QHD. The toxicity of QHD against H. pylori and human gastric epithelial cells was evaluated by the toxicology test and cell counting kit-8 assay. The adhesion model was constructed by incubating H. pylori and gastric mucosal epithelial cells for 2 h. The urease assay was used to examine the antiadhesion effects of QHD, and gene expression of adhesins was evaluated by quantitative polymerase chain reaction. The antioxidant activity was assessed by DCFHDA labeling. To evaluate the anti-inflammatory effect, the levels of pro-inflammatory cytokines in the culture supernatant were detected by enzyme-linked immunosorbent assay. RESULTS: HPLC-QTOF/MS profiling indicated the presence of primary compounds 1-20 in QHD. Drug concentration was determined as 1, 2, and 5 mg/m L by the toxic concentration of QHD against H. pylori and human gastric epithelial cells. QHD prevented H. pylori adhesion to the human gastric epithelial cells and reduced levels of reactive oxygen species. QHD also reduced the level of interleukin-8 and other proinflammatory cytokines that were upregulated by H. pylori infection. CONCLUSION: QHD could inhibit H. pylori adhesion, and exert antioxidant and anti-inflammatory effects in vitro.展开更多

文摘OBJECTIVE:To determine the effect of Traditional Chinese Medicine(TCM)Fuzheng Xuanfei Huashi prescription(扶正宣肺化湿方,FZXF)on lipopolysaccharide(LPS)-induced pneumonia in mice and identify the mechanism of FZXF in the treatment of LPS-induced lung inflammation.METHODS:The pneumonia model was established by intraperitoneal injection of 5 mg/kg LPS in mice.Cytokines were detected by enzyme-linked immuneosorbent assay(ELISA),macrophages in lung tissue were determined by immunofluorescence,and pathwayrelated data were determined by quantitative real-time polymerase chain reaction(qPCR)and Western blot.RESULTS:The liver,thymus,and spleen index values and the levels of aspartate aminotransferase(AST)and alanine aminotransferase(ALT)obviously increased in LPS-treated mice.FZXF decreased the white blood cell count and reduced the increase in the lung wet weight/dry weight ratio caused by LPS.The hematoxylin-eosin staining result showed that FZXF could maintain the integrity of lung tissue structure,alleviate interstitial oedema and alveolar wall thickening,and reduce inflammatory cell infiltration.Moreover,FZXF markedly reduced the expression of proinflammatory cytokines.FZXF also significantly reduced LPS-induced malondialdehyde production and increased superoxide dismutase level in the lung.By immunofluorescence,we found that FZXF could reduce macrophage infiltration.The mRNA expression levels of cyclooxygenase-2(COX-2),prostaglandin E2(PGE2),toll-like receptor 4(TLR4)and nuclear transcription factorκB(NF-κB)in the lung tissue of mice were decreased by treatment with FZXF.In addition,FZXF inhibited the protein expression of TLR4,p-p65 and COX-2.These results indicated that FZXF could inhibit the inflammatory response of LPS induced cytokine storm in mice through TLR4/NF-κB and COX-2/PGE2 signaling pathway.CONCLUSION:These findings were suggested that FZXF prescription suppresses inflammation in LPSinduced pneumonia in mice via TLR4/NF-κB and COX-2/PGE2 pathway.

文摘OBJECTIVE: To investigate the phytochemical profile of Qingre Huashi decoction( 清 热 化 湿 方, QHD) and evaluate the mechanisms rationalizing the use of QHD against Helicobacter pylori(H. pylori)-associated gastritis. METHODS: QHD is composed of 11 herbs, which was prepared by a fixed Pharmacy and concentrated into clear paste. High-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry(HPLC-QTOF/MS) was used to detect the phytochemical profile of QHD. The toxicity of QHD against H. pylori and human gastric epithelial cells was evaluated by the toxicology test and cell counting kit-8 assay. The adhesion model was constructed by incubating H. pylori and gastric mucosal epithelial cells for 2 h. The urease assay was used to examine the antiadhesion effects of QHD, and gene expression of adhesins was evaluated by quantitative polymerase chain reaction. The antioxidant activity was assessed by DCFHDA labeling. To evaluate the anti-inflammatory effect, the levels of pro-inflammatory cytokines in the culture supernatant were detected by enzyme-linked immunosorbent assay. RESULTS: HPLC-QTOF/MS profiling indicated the presence of primary compounds 1-20 in QHD. Drug concentration was determined as 1, 2, and 5 mg/m L by the toxic concentration of QHD against H. pylori and human gastric epithelial cells. QHD prevented H. pylori adhesion to the human gastric epithelial cells and reduced levels of reactive oxygen species. QHD also reduced the level of interleukin-8 and other proinflammatory cytokines that were upregulated by H. pylori infection. CONCLUSION: QHD could inhibit H. pylori adhesion, and exert antioxidant and anti-inflammatory effects in vitro.

文摘BACKGROUND Helicobacter pylori(HP),the most common pathogenic microorganism in stomach,can induce inflammatory reactions in the gastric mucosa,causing chronic gastritis and even gastric cancer.HP infection affects over 4.4 billion people globally,with a worldwide infection rate of up to 50%.The multidrug resistance of HP poses a serious challenge to eradication.It has been monstrated that compared to bismuth quadruple therapy,Qingre Huashi decoction(QHD)combined with triple therapy exhibits comparable eradication rates but with a lower incidence of adverse reactions;in addition,QHD directly inhibit and kill HP in vitro.METHODS In this study,12 HP strains were isolated in vitro after biopsy during gastroscopy of HP-infected patients.In vitro,the minimum inhibitory concentration(MIC)values for clinical HP strains and biofilm quantification were determined through the E-test method and crystal violet staining,respectively.The most robust biofilm-forming strain of HP was selected,and QHD was evaluated for its inhibitory and bactericidal effects on the strain with strong biofilm formation.This assessment was performed using agar dilution,E-test,killing dynamics,and transmission electron microscopy(TEM).The study also explored the impact of QHD on antibiotic resistance in these HP strains with strong biofilm formation.Crystalline violet method,scanning electron microscopy,laser confocal scanning microscopy,and(p)ppGpp chromatographic identification were employed to evaluate the effect of QHD on biofilm in strong biofilm-forming HP strains.The effect of QHD on biofilm and efflux pump-related gene expression was evaluated by quantitative polymerase chain reaction.Non-targeted metabolomics with UHPLC-MS/MS was used to identify potential metabolic pathways and biomarkers which were different between the NC and QHD groups.RESULTS HP could form biofilms of different degrees in vitro,and the intensity of formation was associated with the drug resistance of the strain.QHD had strong bacteriostatic and bactericidal effects on HP,with MICs of 32-64 mg/mL.QHD could inhibit the biofilm formation of the strong biofilm-forming HP strains,disrupt the biofilm structure,lower the accumulation of(p)ppGpp,decrease the expression of biofilm-related genes including LuxS,Spot,glup(HP1174),NapA,and CagE,and reduce the expression of efflux pump-related genes such as HP0605,HP0971,HP1327,and HP1489.Based on metabolomic analysis,QHD induced oxidative stress in HP,enhanced metabolism,and potentially inhibited relevant signaling pathways by upregulating adenosine monophosphate(AMP),thereby affecting HP growth,metabolism,and protein synthesis.CONCLUSION QHD exerts bacteriostatic and bactericidal effects on HP,and reduces HP drug resistance by inhibiting HP biofilm formation,destroying its biofilm structure,inhibiting the expression of biofilm-related genes and efflux pump-related genes,enhancing HP metabolism,and activating AMP in HP.

文摘Sanhan Huashi formula(SHHS),a traditional Chinese medicine(TCM),has shown significant therapeutic effects on coronavirus disease 2019(COVID-19)in clinical settings.However,its specific mechanism and components still require further clarification.In vitro experiments with Vero-E6 cells infected with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)demonstrated that SHHS effectively inhibited viral invasion and proliferation.Complementary in vivo experiments using K18-human angiotensin converting enzyme 2(hACE2)mice exposed to virus-like particles(VLPs)further confirmed that SHHS impeded SARS-CoV-2 entry.Although SHHS did not demonstrate direct antiviral effects in K18-hACE2 mice challenged with SARS-CoV-2,it significantly alleviated pathological damage and decreased the expression of chemokines such as C–C motif ligand(CCL)-2,CCL-3,C–X–C motif ligand(CXCL)-1,CXCL-6,CXCL-9,CXCL-10,and CXCL-11 in the lungs,suggesting that SHHS exerts immunomodulatory and anti-inflammatory effects via the CCL-2–CXCL axis.Additional research using a lipopolysaccharide(LPS)-induced acute lung injury(ALI)and RAW264.7 cell model validated the ability of SHHS to reduce the levels of inflammatory biomarkers,including interleukin(IL)-1β,IL-6,and tumor necrosis factor-α(TNF-α).Using advanced analytical techniques such as ultrahigh-performance liquid chromatography coupled with linear trap quadrupole Orbitrap mass spectrometry(UHPLC-LTQ-Orbitrap-MS)and surface plasmon resonance(SPR),nodakenin was identified as a potent antiviral component of SHHS that targets the 3C-like protease(3CL^(pro)),a finding supported by the hydrogen–deuterium exchange mass spectrometry(HDX-MS)and molecular docking analyses.Furthermore,nodakenin demonstrated a significant antiviral effect,reducing the viral load by more than 66%.This investigation reveals that SHHS can combat COVID-19 by inhibiting viral invasion and promoting anti-inflammatory effects.
文摘Objective To observe the effects of Huashi Tongbi Formula(HTF)on blood lipid levels,endothelial cell function,and gut microbiota in rats with erectile dysfunction(ED).Methods SD rats were randomly divided into blank group,sham operation group,model group,sildenafil group,and HTF low,medium,and high dose groups,with 7 rats in each group.Hyperlipidemia combined with bilateral internal iliac artery ligation were used to establish ED model.After modeling,the sildenafil group received sildenafil(4.5 mg/kg)by gavage,while the HTF group received low,medium,and high doses(3.24,6.48,12.96 g/kg)of HTF by gavage.The other three groups received an equal volume of physiological saline by gavage.After 6weeks of intervention,the intracavernous pressure(ICP)of the penis and mean carotid artery pressure(MAP)were measured using a multi-channel physiological signal recorder,and the ICP/MAP were calculated,the number of erections in rats was recorded.Serum total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDLC)were measured using a fully automated biochemical analyzer.ELISA was used to detect the levels of vascular endothelial growth factor(VEGF),endothelin-1(ET-1)in serum,and microplate method was used to detect the level of nitric oxide(NO)in the corpus cavernosum tissue of rats.16 S rDNA sequencing was used to detect the gut microbiota of rats.Results Compared with baseline,the serum LDL-C levels of rats in each dose group of HTF decreased,HDL-C levels increased(P<0.05),the TC levels of rats in the medium dose group of HTF decreased(P<0.05).Compared with the blank group,the model group showed a decrease in number of erections,ICP/MAP,serum HDL-C,and NO levels in the corpus cavernosum tissue of the penis,while serum TC,LDL-C,VEGF,and ET-1 levels increased(P<0.05).Compared with the sham operation group,the model group showed a decrease in number of erections and an increase in serum VEGF and ET-1 levels(P<0.05).Compared with the model group,the sildenafil group showed a decrease in serum ET-1 levels and an increase in NO levels in the corpus cavernosum tissue of the penis(P<0.05).The levels of serum LDL-C,VEGF,and ET-1 in rats of various doses of HTF decreased,while the level of HDL-C increased(P<0.05).The low dose group of HTF had an increase in the level of NO in the corpus cavernosum tissue of the penis,while the medium dose group of HTF had an increase in the number of erections and a decrease in serum TC levels(P<0.05).Compared with the sildenafil group,the serum LDL-C and VEGF levels of rats in each dose group of HTF decreased,the HDL-C levels of rats in the low and high dose groups of HTF increased,and the ET-1 levels of rats in the low dose group of HTF decreased(P<0.05).Analysis of gut microbiota showed that HTF could affect the structure of gut microbiota.Compared with the blank group,the abundance of Butyricicoccus,Ruminococcus,Prevotellaceae_UCG-OOl,and Anaerotruncus increased in the model group,while the abundance of Candidatus_Stoquefichus,Facklamia,Jeotgalicoccus,and Enterococcus decreased(P<0.05).Compared with the model group,the HTF mediumdose groupSshowedan increase inthe abundance of Staphylococcus,Faecalibacterium,Jeotgalicoccus,Halomonas,Negativibacillus,Achromobacter,Subdoliguranulus,Lachnospiraceae UCG-010,Bilophila,and Nosocomicoccus(P<0.05),while Faecalibacterium,Family_XIll_UCG-001,and Lachnospiraceae_UCG-006,Butyricicoccus,unidentified_Ruminococcaceae,Lachnospiraceae_ND3007_group,and Lactococcus decreased(P<0.05).Conclusion The HTF may improve lipid disorders and vascular endothelial cell function in rats via affecting the abundance and diversity of gut microbiota,thereby to enhance erectile function.

文摘Background:Acute respiratory distress syndrome induced by acute lung injury(ALI)is the main cause for the high mortality of coronavirus disease 2019(COVID-19).Huashi Baidu formula(HSBD)with the effects of eliminating dampness,clearing heat,ventilating lung,and removing toxin has been proven to be effective in the treatment of COVID-19,especially in severe cases.However,the underlying mechanism and target proteins of HSBD remain unclear.Objective:To provide evidence and decipher the mechanism of HSBD in alleviating inflammation and ALI.Materials and Methods:A mouse model of ALI was induced by lipopolysaccharide(LPS),and hematoxylin-eosin staining was used to examine the protective effects of HSBD on the model mice.The cellular thermal shift assay and proteomics analysis were used to predict the target proteins.Furthermore,the A549 cells with peroxiredoxin 5(PRDX5)knockdown were established to validate the predicted proteins.Results:Huashi Baidu formula treatment mitigated ALI and inflammatory cytokine dysfunction in LPS-induced mice,thus exerting a therapeutic effect on COVID-19.Huashi Baidu formula could serve as a therapeutic agent to alleviate inflammation and lung injury via nuclear factorκB and phosphatidylinositol 3-kinase signaling and interleukin 17 inhibition as well as targeting PRDX5,which could be one of the promising targets for treating inflammation.In the A549 cell line with PRDX5 knockdown(si-PRDX5),the anti-inflammation effects of HSBD,including reversing LPS-induced increase in the nitric oxide level and reduction in the hydrogen peroxide content,were attenuated.Thus,HSBD protected A549 cells from LPS-induced inflammation mainly by targeting PRDX5.Conclusions:Huashi Baidu formula alleviates ALI by targeting nuclear factorκB/phosphatidylinositol 3-kinase and PRDX5,as well as inhibiting the immune response induced by IL-17.
