文摘BACKGROUND Rheumatic immune diseases are a group of chronic inflammatory diseases charac-terized by joint and systemic multi-organ involvement,including rheumatoid arthritis,systemic lupus erythematosus,and Sjogren’s syndrome,among others.The pathogenesis of these diseases is related to the abnormal activation and regulatory imbalance of the immune system.The prevalence and morbidity of rheumatic immune diseases are high,imposing a significant burden on patients'quality of life and socio-economic costs.Currently,the treatment of rheumatic immune diseases mainly relies on Western medicine,such as non-steroidal anti-inflammatory drugs,glucocorticoids,disease-modifying antirheumatic drugs,and biologics.However,the therapeutic effects of Western medicine are not ideal,some patients poorly respond or are resistant to Western medicine,and long-term use often causes various adverse reactions.AIM To systematically evaluate the efficacy and safety of Tripterygium wilfordii gly-cosides tablets combined with Western medicine in the treatment of patients with rheumatic immune diseases.METHODS This study conducted a meta-analysis to systematically evaluate the efficacy and safety of Tripterygium wilfordii glycosides tablets combined with Western medicine for patients with rheumatic immune diseases.Chinese and English databases were searched for randomized controlled trials(RCTs)on the treatment of rheumatic immune diseases with Tripterygium wilfordii glycosides tablets combined with Western medicine.The quality of the included studies was assessed using the Cochrane risk of bias assessment tool.Meta-analysis was performed using RevMan 5.4 software.RESULTS The meta-analysis included 11 RCTs involving 1026 patients with rheumatic immune diseases.The combined treatment significantly reduced the risk of disease recurrence(relative risk=1.07,95%confidence interval:1.01-1.15,P<0.05)and showed no significant heterogeneity(I2=0%,P=0.53),indicating that Tripterygium wilfordii glycosides tablets combined with Western medicine is an effective method to reduce the possibility of postoperative recurrence in patients with rheumatic immune diseases.However,due to the limited number and quality of the studies included,these results should be interpreted with caution.CONCLUSION Tripterygium wilfordii glycosides tablets combined with Western medicine is an effective and safe treatment option for patients with rheumatic immune diseases and can be considered a clinical choice.However,more high-quality research is needed to validate this conclusion and provide more solid evidence for clinical practice.

文摘Inspired by brick-and-mortar architectures and suture interfaces,we propose a design of bioinspired nacre-like materials with interlocking sutures to improve the toughness of brittle materials.Laser-engraved glass interlockers are laminated with soft interlayers in a staggered arrangement,and the fundamental mechanical properties of the structure are investigated through experiments and numerical modeling.It is found that the tensile performance,such as the strength and toughness,is strongly affected by the interlocking angle and suture line spacing.The geometric interlocking originated from suture interfaces as well as tablet sliding arising from the staggered arrangement of interlockers cooperatively contribute to enhancing the strength and toughness of this bioinspired design.Additionally,the finite element modeling shows the interfacial failure and plastic deformation,revealing the interplay of the geometric interlocking mechanism and the sliding mechanism.This novel bioinspired design paves a new path for fabrication of structural materials combining high stiffness,high strength,and enhanced toughness.
文摘This article presents a case study of a 20-year-old male patient diagnosed with dilated cardiomyopathy(DCM)(NYHA IV).This condition was diagnosed as"heart failure disease"(water overflowing due to yang deficiency,intermingled phlegm and stasis)in traditional Chinese medicine(TCM).The treatment approach employed a combination of TCM and Western medicine.Western medicine involved the administration of sacubitril valsartan sodium tablets to inhibit ventricular remodeling,in conjunction with diuretics and cardiotonic agents.Initially,TCM utilized a static infusion of Shenfu injection,which was subsequently supplemented with Qiliqiangxin capsules to invigorate qi,warm yang,activate blood circulation,and promote diuresis.After a follow-up period of 3 years,the patient's ejection fraction(EF)improved from 23%to 51%,and the left ventricular end diastolic diameter(LVed)decreased from 68 to 52 mm,accompanied by a significant alleviation of symptoms.These findings indicate that the combined treatment of TCM and Western medicine can synergistically enhance cardiac function and impede the progression of the disease,thereby offering valuable insights for the optimal management of DCM.

文摘OBJECTIVE:To examine Hedan tablet(HDT,荷丹片)'s potential mechanisms in hyperlipidemic rats induced by a high-fat diet(HFD),as well as its regulatory effects and primary active constituents.METHODS:By using ultra-performance liquid chromatography(UPLC)-quadrupole-time-of-flight(QTOF)-tandem mass spectrometry(MS/MS),the components of HDT that can enter the circulatory system were found,aiming to investigate its active constituents with pharmacological effects.Based on network pharmacology approaches,the relevant HDT targets in the therapy of hyperlipidemia were anticipated.The possible mechanism of HDT for hyperlipidemia treatment was verified by in-vivo experiments,and the main active components of HDT for hyperlipidemia treatment were analyzed via in-vitro experiments.RESULTS:UPLC-QTOF-MS/MS identified 30 components of HDT entering the circulatory system,primarily consisting of flavonoids,diterpenoids and alkaloids.The results of a network pharmacology study revealed that 30 active components mostly target 74 genes associated with hyperlipidemia.The primary active ingredients may include quercetin,kaempferol,and epicatechin,and the main gene targets may be tumor necrosis factor(TNF),interleukin-6(IL-6),interleukin 1 beta(IL-1β),etc.The results of animal experiments demonstrated that HDT can significantly regulate the blood lipid level in rats with HFD,improve the degree of inflammatory infiltration in rat liver cells,lower TNF-α,Creactive protein(CRP),IL-6,matrix metalloproteinase 9(MMP9) and malondialdehyde(MDA) levels while raising total superoxide dismutase(T-SOD) level.Meanwhile,HDT can considerably lower the expression of sterol regulatory element-binding transcription factor 2(SREBF2),3-hydroxy-3-methylglutaryl-CoA reductase(HMGCR),and MMP9 while significantly increasing the expression of peroxisome proliferator-activated receptor alpha(PPAR-α) and PPAR-γ.In vitro study confirmed that quercetin and kaempferol could reduce the levels of IL-6,IL1B,MMP9 and HMGCR in the high-fat model of hepatoma G2 cells.CONCLUSIONS:The mechanism by which HDT treats hyperlipidemia involves modification of the lipid metabolism targets such as downregulating SREBF2,HMGCR and MMP9,and upregulating PPAR-α and PPAR-γ,as well as anti-inflammatory and antioxidant actions.This study provides a pharmacological and biological rationale for the use of HDT in clinical hyperlipidemia management.

文摘Rheumatoid arthritis(RA),a globally increasing autoimmune disorder,is associated with increased disability rates due to the disruption of iron metabolism.Tripterygium glycoside tablets(TGTs),a Tripterygium wilfordii Hook.f.(TwHF)-based therapy,exhibit satisfactory clinical efficacy for RA treatment.However,drug-induced liver injury(DILI)remains a critical issue that hinders the clinical application of TGTs,and the molecular mechanisms underlying the efficacy and toxicity of TGTs in RA have not been fully elucidated.To address this problem,we integrated clinical multi-omics data associated with the anti-RA efficacy and DILI of TGTs with the chemical and target profiling of TGTs to perform a systematic network analysis.Subsequently,we identified effective and toxic targets following experimental validation in a collagen-induced arthritis(CIA)mouse model.Significantly different transcriptome–protein–metabolite profiles distinguishing patients with favorable TGTs responses from those with poor outcomes were identified.Intriguingly,the clinical efficacy and DILI of TGTs against RA were associated with metabolic homeostasis between iron and bone and between iron and lipids,respectively.Particularly,the signal transducer and activator of transcription 3(STAT3)–hepcidin(HAMP)/lipocalin 2(LCN2)–tartrate-resis tant acid phosphatase type 5(ACP5)and STAT3–HAMP–acyl-CoA synthetase long-chain family member 4(ACSL4)–lysophosphatidylcholine acyltransferase 3(LPCAT3)axes were identified as key drivers of the efficacy and toxicity of TGTs.TGTs play dual roles in ameliorating CIA-induced pathology and in inducing hepatic dysfunction,disruption of lipid metabolism,and hepatic lipid peroxidation.Notably,TGTs effectively reversed“iron–bone”disruptions in the inflamed joint tissues of CIA mice by inhibiting the STAT3–HAMP/LCN2–ACP5 axis,subsequently leading to“iron–lipid”disturbances in the liver tissues via modulation of the STAT3–HAMP–ACSL4–LPCAT3 axis.Additional bidirectional validation experiments were conducted using MH7A and AML12 cells to confirm the bidirectional regulatory effects of TGTs on key targets.Collectively,our data highlight the association between iron-mediated metabolic homeostasis and the clinical efficacy and toxicity of TGT in RA therapy,offering guidance for the rational clinical use of TwHF-based therapy with dual therapeutic and toxic potential.

文摘BACKGROUND The Correa sequence,initiated by Helicobacter pylori(H.pylori),commonly progresses to gastric cancer through the stage of chronic atrophic gastritis(CAG).Although eradication of H.pylori only reduces the risk of gastric cancer,it does not eliminate the risk for neoplastic progression.Yiwei Xiaoyu granules(YWXY)are a commonly used composite preparation in Chinese clinics.However,the pursuit of excellence in clinical trials and the establishment of standardized animal experiments are still needed to contribute to full understanding and application of traditional Chinese medicine in the treatment of CAG.AIM To demonstrate the effectiveness of YWXY in patients with CAG and spleenstomach deficiency syndrome(DSSS),by alleviating histological scores,improving response rates for pathological lesions,and achieving clinical efficacy in relieving DSSS symptoms.METHODS We designed a double-blind,randomized,controlled trial.The study enrolled seventy-two H.pylori-negative patients(mean age,52.3 years;38 men)who were randomly allocated to either the treatment group or control group in a 1:1 ratio,and treated with 15 g YWXY or 0.36 g Weifuchun(WFC)tablet combined with the respective dummy for 24 wk.The pre-randomization phase resulted in the exclusion of 72 patients:50 participants did not meet the inclusion criteria,12 participants declined to participate,and 10 participants were excluded for various other reasons.Seven visits were conducted during the study,and histopathological examination with target endoscopic biopsy of narrow-band imaging was requested before the first and seventh visits.We also evaluated endoscopic performance scores,total symptom scores,serum pepsinogen and gastrin-17.RESULTS Six patients did not complete the trial procedures.Treatment with YWXY improved the Operative Link on Gastric Intestinal Metaplasia Assessment(OLGIM)stage,compared with WFC(P<0.05).YWXY provided better relief from symptoms of DSSS and better improvement in serum gastric function,compared with WFC(P<0.05).CONCLUSION YWXY compared with WFC significantly reduced the risk of mild or moderate atrophic disease,according to OLGIM stage,significantly relieved symptoms of DSSS,and improved serum gastric function.

文摘Xiaoyankangjun tablet(XYKJP)is a traditional Chinese medicine formulation used to treat intestinal disorders in clinical practice.However,the specific therapeutic mechanism of action of XYKJP in colitis has not yet been elucidated.This study aimed to reveal the multifaceted mechanisms of action of XYKJP in treating colitis.The model established based on DSS-induced colitis in C57BL/6 mice was employed to estimate the effect of XYKJP on colitis,which was then followed by histological assessment,16S rRNA sequencing,RT-qPCR,ELISA,and Western blot.XYKJP alleviated the symptoms of DSS-induced colitis mainly by reducing oxidative stress,inflammatory responses,and intestinal mucosal repair in colitis tissues.In addition,XYKJP regulated the intestinal flora by increasing the relative abundance of Akkermansia and Bifidobacterium and reducing the relative abundance of Coriobacteriaceae_UCG-002.Mechanistically,XYKJP increased the content of short-chain fatty acids(SCFAs)in the feces,particularly propanoic acid and butyric acid,activated their specific receptor GPR43/41,furthermore activated the Nrf2/HO-1 pathway,and suppressed the JAK2/STAT3 pathway.XYKJP significantly alleviated the symptoms of experimental colitis and functioned synergistically by regulating the intestinal flora,increasing the production of SCFAs,and activating their specific receptors,thereby repressing oxidative stress and inflammation.
文摘Objective:To investigate the therapeutic effect of Biling Weitong Granules combined with oryz-aspergillus enzyme and pancreatin tablets on patients with reflux esophagitis with functional dyspepsia.Methods:Sixty patients diagnosed with reflux esophagitis with functional dyspepsia who were admitted to the Affiliated Hospital of Hebei University between June 2020 and June 2023 were selected and divided into two groups:the control group and the observation group,each consisting of 30 cases.The control group received oryz-aspergillus enzyme and pancreatin tablets only,while the observation group received Biling Weitong Granules in addition to the tablets.The clinical efficacy,Chinese medicine syndrome points,esophageal kinetic indexes,gastrointestinal hormone levels,and therapeutic safety of both groups were evaluated.Results:The total efficiency of the observation group reached 93.33%,significantly higher than the 73.33%of the control group(P<0.05).After treatment,patients in the observation group exhibited significantly lower scores for Chinese medicine symptoms such as early satiety,belching,abdominal distension,abdominal pain,and loss of appetite compared to the control group(P<0.05).Furthermore,the observation group showed significantly higher upper esophageal sphincter pressure,lower esophageal sphincter pressure,and distal esophageal contraction scores compared to the control group(P<0.05).Additionally,levels of gastric motility hormone,vasoactive intestinal peptide,and gastrin were significantly higher in the observation group compared to the control group(P<0.05).Throughout the treatment period,there was no significant difference in the incidence of adverse reactions between the two groups,indicating comparable safety of the two treatment modalities(P>0.05).Conclusion:The combination of Biling Weitong Granules with oryz-aspergillus enzyme and pancreatin tablets demonstrates significant efficacy in the treatment of reflux esophagitis with functional dyspepsia,with a better safety profile.This finding warrants further clinical promotion.

文摘The structures of solid dosage forms determine their release behaviors and are critical attributes for the design and evaluation of the solid dosage forms.Here,the 3D structures of doxazosin mesylate sustained-release tablets were parallelly assessed by micro-computed tomography(micro-CT).There were no significant differences observed in the release profiles between the RLD and the generic formulation in the conventional dissolution,but the generic preparation released slightly faster in media with ethanol during an alcohol-induced dose-dumping test.With their 3D structures obtained via micro-CT determination,the unique release behaviors of both RLD and the generic were investigated to reveal the effects of internal fine structure on the release kinetics.The structural parameters for both preparations were similar in conventional dissolution test,while the dissolutions in ethanol media showed some distinctions between RLD and generic preparations due to their static and dynamic structures.Furthermore,the findings revealed that the presence of ethanol accelerated dissolution and induced changes in internal structure of both RLD and generic preparations.Moreover,structure parameters like volume and area of outer contour,remaining solid volume and cavity volumewere not equivalent between the two formulations in 40%ethanol.In conclusion,the structure data obtained from this study provided valuable insights into the diverse release behaviors observed in various modified-release formulations in drug development and quality control.

文摘Owing to its high sensitivity,selectivity,and accuracy,liquid chromatography coupled with mass spectrometry(LC-MS)is commonly employed to screen,confirm,and quantify impurities in drugs[1].However,LC-MS has certain drawbacks such as complicated pretreatment steps,long analysis time,large consumption of organic solvents,high maintenance costs,and,most notably,the need for high-pressure pumps and compatible hardware because of the high column backpressure[2].In this study,a two-dimensional(2D)microscale carbon fiber(CF)/active carbon fiber(ACF)system combined with a quadrupole time-of-flight high-resolution mass spectrometry(2DmCFs-QTOF-HRMS)system was developed to rapid screening impurities in the typical three generations of oral cephalosporins,i.e.,cephalexin tablets(CPXTs),cefuroxime axetil tablets(CFATs),and cefixime tablets(CFXTs)(Fig.S1).The“fuzzy chromatographic separation”sample pretreatment method separates complex samples into high-,medium-,and weak-polar fractions for successive detection of MS,achieving effective reduction of the ion suppression effect in electrospray ionization(ESI)-MS and improving the MS detection sensitivity.Compared to high performance liquid chromatography(HPLC)-MS,this method has distinct advantages such as less organic solvent consumption(1.5 mL),shorter separation and analysis times(5 min),more information on impurities,and high reproducibility.

文摘OBJECTIVE:To study the effect of Jiangzhi Xiaoban tablet(降脂消斑片,JZXB)on toll-like receptor 4(TLR4)/nuclear factor-kappa B(NF-κB)/Nod-like receptor protein 3(NLRP3)signaling pathway expression in atherosclerosis(AS)mice by establishing a mouse model of AS,and to explore its mechanism of prevention and treatment of AS.METHODS:Sixty-four male C57BL/6J mice were randomly divided into two groups,12 in the normal control group and 52 in the model group(MOD).Seven weeks later,two mice in each of the above two groups were randomly sacrificed,and the whole aortic tissue of the mice was taken out for hematoxylin-eosin staining.After successful modeling,50 mice in the modeling group were randomly divided into 5 groups:MOD,atorvastatin group(ATO),low-dose group of JZXB(JZXB-L),middle-dose group of JZXB(JZXB-M),and high-dose group of JZXB(JZXB-H),10 mice in each group.The mice in each group were killed after 6 weeks of preventive administration.HE staining was used to observe the pathological changes of aorta in AS mice.The levels of serum triglyceride(TG),total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C)and high-density lipoprotein cholesterol(HDL-C)were detected by automatic biochemical analyzer.The levels of inflammatory factor interleukin-1β(IL-1β)were detected by enzyme linked immunosorbent assay.The expression of TLR4,NF-κB and NLRP3 proteins in aortic tissue was detected by immunohistochemistry.RESULTS:Compared with the MOD,the levels of serum TC,TG and LDL-C in the JZXB-H and ATO were significantly decreased,while the level of HDL-C was significantly increased.The levels of serum TG,LDL-C in the JZXB-M were significantly decreased,and the level of HDL-C was significantly increased.Compared with the MOD,the levels of IL-1βwere significantly decreased,aortic lesions were significantly improved,and the expression of TLR4,NF-κB,and NLRP3 proteins in the aortic tissue was significantly decreased in the JZXB-H,JZXB-M,and ATO.CONCLUSION:JZXB has inhibitory effect on atherosclerosis in mice,and its mechanism may be through regulating the TLR4/NF-κB/NLRP3 signaling pathway and reducing the inflammatory response,so as to play a role in inhibiting atherosclerosis.
文摘OBJECTIVE:To investigate the potential pharmacological mechanism of Danlou tablet(丹蒌片,DLT)with a long-term clinical application in the treatment of myocardial ischemia/reperfusion(I/R)injury through network pharmacology,molecular docking and experimental verification.METHODS:The main chemical ingredients in DLT were retrieved from the Traditional Chinese Medicine(TCM)System Pharmacology Database,the TCM information database,the bioinformatics analysis tool for molecular mechanism of TCM,and HERB database.Disease targets of I/R were accessed from the databases of Online Mendelian Inheritance in Man,Gene Cards,Therapeutic Target Database,and Dis Ge NET database.The overlaying genes of DLT and I/R were obtained from the Venny online platform.The core targets and proteinprotein interaction network were constructed and analyzed via the Search Tool for the Retrieval of Interacting Genes Proteins database and Cytoscape software.Furthermore,Gene Ontology(GO)analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis were performed by the Metascape platform.Based on the results,the component-target-pathway network was constructed and drafted via the Cytoscape software and the platform of Bioinformatics.Furthermore,we performed molecular docking to predict the binding information between chemical molecules and target proteins.Finally,oxygenglucose deprivation/recovery(OGD/R)-induced H9c2 cardiomyocytes were used to validate the results of network pharmacology in vitro.RESULTS:A total of 189 active chemical components in DLT and 849 correlative targets of I/R were screened.Of note,133 overlaying genes found from the Venny online platform were concentrated into 28 core genes.Furthermore,the GO and KEGG pathway enrichment analysis presented that DLT might participate in 42 types of GO molecular functions,747 types of GO biological processes,19 types of GO cellular components,and 140 kinds of pathways to treat I/R.In the component-targetpathway network,the indirect relationship between herbs and their possible effective pathways was clarified.Based on the molecular docking,we speculated that Baicalein-prostaglandin G/H synthase 2(PTGS2)with-3.24 kcal/mol,Luteolin-heat shock protein 90 alpha family class A member 1(HSP90AA1)with-3.22 kcal/mol,Baicalein-HSP90AA1 with-3.13 kcal/mol,and QuercetinHSP90AA1 with-3.05 kcal/mol possessed the strongest binding force of less than-3 kcal/mol,sequentially.Experimental verification showed that Quercetin,Luteolin,and Baicalein could increase the relative cell viability of OGD/R-stimulated cardiomyocytes,probably by suppressing PTGS2,and activating HSP90AA1 and estrogen receptor 1 expression.CONCLUSIONS:We predicted the potential active compounds as the material basis of DLT that may provide a new approach to elucidate the novel pharmacological mechanism underlying the treatment of cardiac I/R damage.
