Inflammatory diseases (IDs) are a general term of diseases characterized by chronic inflammation as the primary pathogenetic mechanism, which seriously affect the quality of patient′s life and cause significant social and medical burden. Current drugs for IDs include nonsteroidal anti-inflammatory drugs, corticosteroids, immunomodulators, biologics, and antioxidants, but these drugs may cause gastrointestinal side effects, induce or worsen infections, and cause non-response or intolerance. Given the outstanding performance of metal polyphenol network (MPN) in the fields of drug delivery, biomedical imaging, and catalytic therapy, its application in the diagnosis and treatment of IDs has attracted much attention and significant progress has been made. In this paper, we first provide an overview of the types of IDs and their generating mechanisms, then sort out and summarize the different forms of MPN in recent years, and finally discuss in detail the characteristics of MPN and their latest research progress in the diagnosis and treatment of IDs. This research may provide useful references for scientific research and clinical practice in the related fields.

Aim To explore the mechanism of ligustil-ide(LIG)improving demyelination by inhibiting in-flammatory response in mice with distal middle cerebral artery occlusion(dMCAO)through AIM2/caspase-1 signal pathway.Methods Thirty C57BL/6N male mice were randomly divided into three groups:sham operation group(Sham group,n=10),model group(dMCAO group,n=10)and treatment group(LIG group,n=10).The dMCAO mouse model was estab-lished by electrocoagulation in dMCAO group and LIG group.The mice were scored by Longa after waking up,and the changes of cerebral blood flow were moni-tored by laser speckle blood flow imaging system after dMCAO.One hour after modeling,LIG(30 mg·kg-1·d-1)was injected intraperitoneally in LIG group,and the same amount of normal saline was injected in sham group and dMCAO group for one week until the end of the experiment.The mice in each group were stained with TTC,and the brain injury was observed pathologically.Fatigue turning bar test and open field test were used to evaluate the motor function and anxie-ty degree of mice,and then the brain tissues of mice were taken for black gold staining to compare the chan-ges of myelin sheath in each group.Immunofluores-cence staining was used to detect the average fluores-cence intensity of MBP,IBA1 and GFAP in CC,CPU and CX regions of mouse brains.ELISAwas used to de-tect the contents of TNF-α,IL-6,IL-1 β,IL-17A and BDNF in brain tissue proteins of mice.Western blot-ting was used to detect the protein expressions of AIM2,caspase-1 and ASC-in each group.Results Compared with the dMCAO group,the infarct area was reduced,the behavior was significantly improved and the demyelination was reduced in the LIG group.The expression of MBP protein in CC,CPU and CX regions increased(P<0.05),the expression of IBA1 in CX decreased(P<0.01),and the expression of GFAP in-creased in CC,CPU and CX regions(P<0.01).The results of ELISA showed that the levels ofTNF-α(P<0.01),IL-6(P<0.01),IL-1β(P<0.05)and IL-17A(P<0.01)significantly decreased,while the ex-pression of BDNF increased(P<0.05).The protein expression levels of AIM2,caspase-1 and ASC in mouse brain decreased after treatment(P<0.01).Conclusion LIG has a protective effect on demyelina-tion in dMCAO mice,which may be related to the inhi-bition of AIM2/caspase-1 signaling pathway and in-flammation and to the promotion of BDNF secretion.

Objective To investigate the perioperative management of antithrombotic drugs in patients undergoing non-cardiac surgery.Methods Patients on long-term antithrombotic drugs who underwent non-cardiac surgery in our hospital were included.Through interviews with patients and physicians,perioperative antithrombotic medication regimens were reviewed and compared with the"Multidisciplinary Expert Consensus on Perioperative Management of Antithrombotic Therapy"to evaluate compliance with consensus and analyze influencing factors.Results A total of 372 patients were included in the analysis.Among them,355 patients were on long-term antiplatelet therapy alone,and 17 were on long-term oral anticoagulantion.364(97.8%)discontinued antithrombotic medications prior to surgery.109 patients(29.3%)received low molecular weight heparin(LMWH)bridging therapy.Among the 355 patients on antiplatelet therapy,108(30.4%)had discontinuation durations consistent with the consensus recommendations,while 186(52.4%)discontinued medications for longer periods.Postoperatively,the average hospital stay for antiplatelet therapy patients was 6.64 days,with only 37(10.4%)resuming therapy during hospitalization.The average hospital stay for patients on anticoagulants was 9.94 days,with only 2(11.8%)resuming therapy during hospitalization.Regarding perioperative risk assessment,only 40(10.8%)of patients underwent additional internal medical evaluation for thromboembolic risk after medication discontinuation,with the remainder assessed soly by surgeons.Coronary heart disease was an independent risk factor associated with internal medical evaluation(OR 2.851,95%CI 1.160-7.011,P=0.022).For bleeding risk assessment,surgeons evaluations aligned with the consensus in 68.0%of cases,but surgeons tended to underestimate risk compared to the consensus.Conclusions In this single-center study,perioperative antithrombotic management showed low compliance with expert consensus,characterized by prolonged preoperative medication discontinuation,high rates of LMWH bridging,and low postoperative in-hospital resumption of therapy.A robust multidisciplinary collaboration system should be established to enhance comprehensive patient assessment.

Aging is the result of the accumulation of various molecular and cellular damages over time,encompassing 12 characteristic hallmarks divided into three categories.These include primary hallmarks such as genomic instability,telomere attrition,epigenetic alterations,loss of proteostasis,and disabled macroautophagy;antagonistic hallmarks like deregulated nutrient sensing,mitochondrial dysfunction,and cellular senescence;and integrative hallmarks including stem cell exhaustion,altered intercellular com-munication,chronic inflammation and dysbiosis.Therefore,investigating cellular signaling factors within a single pathway is insufficient to comprehensively understand the complex mechanisms underlying aging.Casein kinase Ⅱ(CK2),one of the earliest identified protein kinases,is capable of phosphorylating ser-ine/threonine/tyrosine residues on hundreds of substrates.It exhibits highly constitutive expression and activity,and is extensively involved in the regulation of cellular processes such as proliferation,differenti-ation,apoptosis,stress response,metabolism,and immune function.CK2 plays a unique role in coordi-nating the cross-talk and integration of various signaling pathways,which is crucial for maintaining cell survival and homeostasis.Recent studies have revealed that CK2 exhibits perturbations in both expression levels and enzymatic activity during aging process,with notable heterogeneity observed across different animals,tissues and cellular models.Overall,the downregulation of CK2 expression not only promotes the development of primary hallmarks but also alleviates antagonistic hallmarks and ameliorates integrative hallmarks of aging,demonstrating dual effect and interconnected mechanisms.Notably,aberrant activa-tion in CK2 expression and activity are associated with various aging-related diseases,including cancer,cardiovascular diseases,chronic metabolic disorders,neurodegenerative diseases and skeletal degenera-tive conditions.Therefore,maintaining CK2 homeostasis may represent an effective strategy for delaying aging.This review summarizes the latest advances in CK2 and aging research,providing not only deeper insights into the common mechanisms underlying aging and aging-related diseases,but also a theoretical foundation for identifying potential targets for the early prevention of aging-related diseases.

The Lambl's excrescences(LEs)are elongated valvular fronds with excessive mobility,commonly found at the closure lines of heart valves.These filiform projections are thin and long,exhibiting undulating independent motion.LEs predominantly occur on the ventricular side of the aortic valve and on the atrial side of the mitral valve,although there have been documented cases involving tricuspid,pulmonic,and prosthetic valves.To detect LEs,transesophageal echocardiography is often recommended.The high stress experienced by left-sided valves during closure can lead to tears or lesions in the endocardium that initiate LEs pathogenesis.In this particular case study,we present a patient who presented with acute non-ST-segment elevation myocardial infarction alongside LEs located on the non-coronary cusp of the aortic valve.This specific anatomical location posed significant challenges during percutaneous coronary intervention(PCI),as it required direct contact between the guiding catheter and the aortic valve,thereby increasing the risk of dislodging the LEs.Fortunately,our team successfully performed PCI without encountering any notable complications or embolic events.

Aim To systematically investigate the ac-tive components,targets,and regulatory pathways of Po-lygonum capitatum in intervening atherosclerosis(AS)through network pharmacology,molecular docking and animal experiments.Methods Active components of Polygonum capitatum and AS-related targets were screened and identified through database searches.Protein-protein interaction(PPI)network analysis was performed using the STRING database,followed by GO and KEGG enrichment analyses via the David plat-form.Molecular docking validation was conducted with AutoDock.An AS model was established in Syrian golden hamsters fed a high-fat diet.Predicted pathways and targets were validated using qPCR,ELISA,and histopathological assessment of aortic and hepatic tis-sues via HE staining.Results Network pharmacology identified 27 potential active components of Polygonum capitatum(primarily flavonoids such as quercetin and luteolin)and 110 drug-disease intersection targets,in-cluding core targets MMP-9,ALB,and AKT1.GO and KEGG analyses enriched 593 and 125 pathways,re-spectively,with the NF-κB inflammatory pathway,TNF signaling pathway and lipid metabolism/atherosclerosis pathways highlighted as key mechanisms.Animal ex-periments demonstrated that Polygonum capitatum im-proved serum lipid profiles(reduced TC,TG,LDL-C)in AS hamsters,suppressed the MMP-9/NF-κB signa-ling pathway(downregulated MMP-9,p65 phosphoryla-tion,TNF-α,and IL-6),and inhibited VSMC synthetic phenotypic transformation(upregulated α-SMA and myocardin)by downregulating MCPIP1.Additionally,Polygonum capitatum ameliorated aortic lesions and he-patic lipid deposition in AS hamsters.Conclusions Polygonum capitatum alleviates AS by synergistically regulating the MMP-9/NF-κB/MCPIP1 axis through flavonoid components,suppressing vascular inflammato-ry cascades and maintaining VSMC contractile pheno-types.This reflects Polygonum capitatum's multi-com-ponent,multi-pathway,and multi-target characteristics in combating AS.
