文摘Burn infection is one of the most common and severe complications in burn patients and a major factor contributing to high mortality rates.The loss of skin barrier function and the immunosuppressive state following burns make patients highly susceptible to wound infections,which can progress to systemic sepsis.Although burn wounds are initially sterile,they are rapidly colonized by Gram-positive bacteria(e.g.,Staphylococcus aureus)within a short period,followed by colonization with Gram-negative bacteria(e.g.,Pseudomonas aeruginosa),thereby increasing therapeutic challenges.Current clinical management relies on a multidisciplinary collaborative approach,combining conventional antibiotics,emerging therapies,and comprehensive care strategies.Among these methods,early intervention,precise treatment administration,and prevention and control are critical to improving patient survival and prognosis.In recent years,drug-loaded hydrogels,as a class of wound repair materials characterized by biocompatibility,controlled drug release,and multifunctional integration,have demonstrated significant advantages in the treatment of burn infections.They can effectively inhibit pathogenic microorganisms,alleviate inflammation,and promote tissue regeneration.This review systematically summarizes recent research advances in the application of drug-loaded hydrogels for the treatment of infected burn wounds,aiming to provide a reference for their further development and clinical translation.

文摘As natural killer(NK)cells eliminate cancer cells and virus-infected cells,as well as modulate various other medical conditions,including aging-associated conditions such as neurodegenerative disorders,understanding NK cell regulation is of considerable clinical importance.This article reviews the role of circadian processes(melatonin and the cortisol system),aryl hydrocarbon receptor,and vagal nerve in the modulation of NK cell function,highlighting the importance of the endogenous mitochondrial melatonergic pathway in NK cells.As circadian and exogenous melatonin increase NK cell cytotoxicity,the presence of the endogenous melatonergic pathway may be of some importance not only to NK function and immune checkpoint regulation but also from the efflux of melatonin,which decreases tumor cell survival,proliferation,and metastasis,as well as decreasing immune checkpoint ligands,such as programmed cell ligand 1(PD-L1).NK cell melatonergic pathway regulation may therefore have significant impacts not only on NK cell cytotoxicity but also on the intercellular interactions within tumors and other pathological microenvironments.As melatonin has anti-viral effects,the regulation of the NK cell melatonergic pathway can have wider impacts on how NK cells regulate viral infections,including in the course of viral-induced susceptibility to neurodegenerative conditions.Recent data indicate that the endogenous melatonergic pathway is regulated by interactions of signal transducer and activator of transcription(STAT)3 and nuclear factor kappa-light-chain-enhancer of activated B cells(NF-κB)dimer composition.As both STAT3 and NF-κB dimer composition modulate NK cells,their interaction in the modulation of the NK cell melatonergic pathway will be important to determine.This has significant future research and treatment implications,including improving the clinical efficacy of current treatment approaches such as immune checkpoint inhibition and chimeric antigen receptor(CAR)NK cell therapy,and may accelerate a means of preventing cancer.

文摘Recent increases in infectious diseases affecting the central nervous system have raised concerns about their role in neuroinflammation and neurodegeneration.Viral pathogens or their products can invade the central nervous system and cause damage,leading to meningitis,encephalitis,meningoencephalitis,myelitis,or post-infectious demyelinating diseases.Although neuroinflammation initially has a protective function,chronic inflammation can contribute to the development of neurodegenerative diseases.Mechanisms such as protein aggregation and cellular disturbances are implicated with specific viruses such as herpes simplex virus type 1 and Epstein-Barr virus being associated with Alzheimer's disease and multiple sclerosis,respectively.Extracellular nucleotides,particularly adenosine triphosphate and its metabolites are released from activated,infected,and dying cells,acting as alarmins mediating neuroinflammation and neurodegeneration.When viruses infect central nervous system cells,adenosine triphosphate is released as an alarmin,triggering inflammatory responses.This process is mediated by purinergic receptors,divided into two families:P1,which responds to adenosine,and P2,activated by adenosine triphosphate and other nucleotides.This review highlights how specific viruses,such as human immunodeficiency virus type 1,Theiler's murine encephalomyelitis virus,herpes simplex virus type 1,Epstein-Barr virus,dengue virus,Zika virus,and severe acute respiratory syndrome coronavirus 2,can initiate inflammatory responses through the release of extracellular nucleotides,particularly adenosine triphosphate,which act as critical mediators in the progression of neuroinflammation and neurodegenerative disorders.A better understanding of purinergic signaling pathways in these diseases may suggest new potential therapeutic strategies for targeting neuroinflammation to mitigate the long-term consequences of viral infections in the central nervous system.

文摘Mucormycosis is an invasive fungal infection with an acute onset,rapid progression,and high mortality rate.Since its incidence is lower than that of common fungal infections such as Aspergillus,Candida,and Cryptococcus,it is often overlooked in clinical practice.[1]However,in recent years,the incidence of mucormycosis has increased worldwide,potentially correlating with the growing population of diabetic patients.
文摘Surgical site infections remain a significant challenge in gastrointestinal surgery,despite advances in surgical techniques and antimicrobial therapy.Wang et al’s retrospective analysis highlights the transformative potential of comprehensive perioperative disinfection and isolation protocols in gastrointestinal surgery,demonstrating a 55%reduction in postoperative infection rates and attenuation of systemic inflammation.Their findings underscore the critical role of multidisciplinary strategies—such as preoperative povidone-iodine decolonization,intraoperative laminar airflow systems,and strict postoperative wound care—in mitigating infection risk and preserving organ function.However,the study revealed persistent gaps in protocol standardization and compliance monitoring,particularly in resource-limited settings.Although these measures reduce reliance on antibiotics and align with global antimicrobial resistance containment efforts,challenges such as the high cost of technology and issues with contextual adaptability warrant urgent attention.This study conclusively demonstrated that structured perioperative disinfection protocols significantly transform surgical outcomes by creating comprehensive infection barriers that extend beyond traditional antibiotic prophylaxis.Future priorities include prospective multicenter trials to validate efficacy,cost-benefit analyses for equitable implementation,and integration of artificial intelligence-driven innovations to optimize infection prevention.This study redefines infection control as a cornerstone of surgical quality,urging collaborative action to bridge the gap between clinical evidence and real-world practice.
