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.

文摘Osteomyelitis remains a global challenge in the field of orthopedics.Even after standard debridement and antibiotic-assisted treatment,the long-term recurrence rate remains at 20%-30%.Given the dynamic changes in immune responses and defense mechanisms during bone infection,as well as the complex“race for the surface”involving bacterial adhesion and host cells(macrophages and tissue cells)on implant surfaces,biomaterials with immunomodulatory functions have attracted considerable attention.Macrophages,as crucial components of the immune system,participate in the inflammatory regulation and tissue remodeling of bone infections through highly plastic polarization mechanisms after bacterial invasion.The different microenvironmental characteristics and therapeutic needs at different stages of bone infection highlight the promising applications of biomaterials capable of macrophage polarization remodeling and sequential regulation.In this review,we provide a detailed discussion of the complex immune regulatory patterns in the bone infection microenvironment and the critical functions of macrophage polarization.We then explore how implant surface properties influence bacterial adhesion and macrophage function,highlighting the importance of achieving precise and dynamic regulation of macrophage polarization based on the Race for the Surface theory.Furthermore,we focus on recent advances,potential challenges,and opportunities in biomaterial-mediated macrophage polarization remodeling and sequential modulation strategies across different stages of osteomyelitis,aiming to offer insights that may accelerate the clinical translation of novel biomaterial-based macrophage immunotherapies.

文摘Respiratory infections are associated with high morbidity and mortality and are a major global health problem[1].Acute respiratory infections are caused by multiple respiratory pathogens,including viruses and bacteria.Viral-bacterial co-infections,which have become increasingly common and a global concern,can lead to substantial complications,causing higher morbidity and adverse prognosis[2].Previous studies have reported low positive detection rates of targeted pathogens related to acute respiratory infections,owing to the limited number of detected pathogens and variations in the sensitivity of diagnostic methods[3-4].Low positive detection rates may impede our understanding of respiratory pathogen characteristics and hamper the development of precise treatment and prevention strategies.
文摘BACKGROUND The application of perioperative disinfection and isolation measures to patients undergoing gastrointestinal surgery with postoperative infection can provide a data reference for reducing the postoperative infection rate,improving post-operative biochemical markers,and enhancing postoperative recovery outcomes.AIM To explore the effectiveness of perioperative disinfection and isolation measures in controlling postoperative infection following gastrointestinal surgery.It also sought to compare infection rates and biochemical markers between the obser-vation and control groups and evaluate the impact of disinfection and isolation measures on reducing postoperative complications.METHODS A retrospective analysis was conducted.Ninety-six patients who underwent gastrointestinal surgery between January 2022 and December 2023 were selected and divided into an observation group and a control group,with 48 cases in each.The observation group received disinfection and isolation measures during the perioperative period,whereas the control group received standard nursing care.The incidence of infection,white blood cell count,C-reactive protein levels,hemoglobin levels,and liver function markers(alanine aminotransferase,aspartate aminotransferase,creatinine,and blood urea nitrogen)were monitored postoperatively in both groups.RESULTS The postoperative infection rate in the observation group was significantly lower than that in the control group(P<0.05).White blood cell and C-reactive protein levels decreased significantly after surgery in the observation group and were significantly lower than those in the control group(P<0.05).Alanine aminotransferase,aspartate aminotransferase,creatinine,and blood urea nitrogen levels in the observation group were lower than those in the control group on postoperative days 1 and 3,showing a significant difference(P<0.05).CONCLUSION Perioperative disinfection and isolation measures effectively reduce postoperative infection rates in gastrointestinal surgery patients and improve biochemical markers,thereby enhancing recovery outcomes.This study provides a valuable basis for postoperative infection control and has significant clinical applications.
