Extracellular vesicles (EVs) are pivotal mediators of intercellular communication within the tumor immune microenvironment (TME). They are broadly categorized into exosomes, microvesicles, and apoptotic bodies based on their distinct biogenesis pathways. Exosomes originate from the endosomal system via multivesicular body fusion, microvesicles bud directly from the plasma membrane, and apoptotic bodies are released during programmed cell death. By shuttling diverse bioactive cargoes—including proteins, lipids, and nucleic acids such as mRNA, miRNA, and DNA—EVs exert dual modulatory effects on tumor initiation, progression, and immune evasion. Importantly, EVs exhibit remarkable compositional heterogeneity that is intrinsically linked to their cellular origin. Tumor-derived EVs (TDEVs) are typically enriched with immunosuppressive molecules like PD-L1, TGF‑β, and miR-21, which promote tumor immune escape and metastasis. In contrast, EVs derived from immune cells, such as dendritic cells or cytotoxic T lymphocytes, often carry immunostimulatory components including antigens, co-stimulatory molecules, and granzymes, thereby potentiating anti-tumor immunity. This review systematically delineates the biogenesis and molecular composition of EVs, with a particular emphasis on their dynamic regulatory functions within the TME. Specifically, we discuss how EVs mediate intricate crosstalk between immune and tumor cells, facilitating signal transfer that reshapes immune surveillance. For instance, TDEVs can induce macrophage polarization toward an M2-like pro-tumor phenotype, while also suppressing natural killer cell cytotoxicity and dendritic cell maturation. The clinical utility of EV-associated biomarkers in liquid biopsy is increasingly recognized. Circulating EVs carry tumor-specific molecular signatures that mirror the genetic and proteomic alterations of primary tumors, enabling non-invasive early diagnosis, molecular subtyping, and real-time monitoring of therapeutic responses. Their natural biocompatibility, low immunogenicity, and intrinsic ability to traverse biological barriers make them ideal candidates for drug delivery systems. This review explores cutting-edge applications, including the use of EVs in immune checkpoint blockade therapy—for instance, engineered EVs displaying anti-PD-1 antibodies or carrying siRNA to silence immunosuppressive genes. Moreover, EV-based tumor vaccines are being developed, leveraging dendritic cell-derived EVs loaded with tumor antigens to elicit potent T cell responses. The feasibility of loading EVs with therapeutic molecules such as chemotherapeutic agents, oncolytic viruses, or CRISPR-Cas9 components is also under active investigation. The advent of engineered EVs has further expanded their therapeutic potential. Through surface modification or cargo encapsulation, EVs can be tailored for targeted delivery and controlled release, enhancing precision immunotherapy. However, several hurdles impede clinical translation. Current isolation and purification methods, such as ultracentrifugation and size-exclusion chromatography, suffer from low yield and purity. Distinguishing EV subpopulations remains technically challenging due to overlapping size and marker expression. Moreover, the lack of standardized protocols for EV production, characterization, and quality control poses significant barriers to regulatory approval and clinical adoption. Looking forward, the convergence of multi-omics technologies with artificial intelligence offers a powerful approach to decipher EV heterogeneity and identify robust diagnostic signatures. Machine learning algorithms can integrate proteomic, transcriptomic, and lipidomic data from large patient cohorts to construct predictive models for cancer diagnosis and prognosis. Concurrently, advances in bioengineering are enabling the design of next-generation EVs with enhanced targeting specificity, on-demand drug release, and reduced off-target effects. Future efforts should also focus on establishing good manufacturing practice (GMP)‑compliant production processes and conducting rigorous preclinical and clinical evaluations. In summary, this review provides a comprehensive overview of EV biology, their multifaceted roles in the TME, and their transformative potential in cancer diagnostics and therapeutics. By addressing current challenges and leveraging emerging technologies, EV-based strategies are poised to revolutionize precision oncology.

OBJECTIVE To formulate Guidelines for the standardized implementation of pharmacist-managed clinics （ 2026 edition ） in response to the challenges faced by such clinics in China， including uneven development， large discrepancies in service specifications， insufficient patient awareness， and limited medical insurance coverage. METHODS Led by the Pharmaceutical Affairs Professional Committee of the Chinese Hospital Association， the Evidence-based Pharmacy Professional Committee of the Chinese Pharmaceutical Association， and the Hospital Pharmacy Professional Committee of the Cross-strait Medical and Health Exchange Association， a total of 19 domestic hospital pharmacy experts were organized. Through a systematic review of national policies and literature research， current practical experience was summarized. Consensus on the contents of the guidelines was reached after in-depth discussions. RESULTS &CONCLUSIONS The guidelines covered five sections： definition and connotation of pharmacist-managed clinics， establishment requirements， implementation and management， post competency， and practical research. Firstly， the definition and connotation included three operational forms of pharmacist-managed clinics （independent mode， physician-pharmacist joint mode， and online pharmacist-managed clinic mode） and classified service modes （specialty-specific， drug-specific， and disease-specific pharmacist-managed clinics）. The establishment requirements were further refined， covering system construction （pharmaceutical service management system， quality control and assessment mechanism）， personnel qualifications （professional credentials， continuing education and professional training， etc）， service recipients， as well as service venues and facilities. Subsequently， the implementation and management of pharmacist-managed clinics were proposed， involving service procedures， intervention measures， documentation and records， patient education and follow-up， humanistic care， as well as risk management and quality control. Finally， post competency encompassed the competency requirements for pharmacists providing services in pharmacist-managed clinics， as well as the suggestions on teaching methods； practical research encouraged the conduct of high-quality pharmaceutical practice in the setting of pharmacist-managed clinics. The guidelines provide valuable guidance for the standardized implementation of pharmacist-managed clinics in China in terms of establishment， management， teaching， and research， fill the guideline gap in this field， and can promote the high-quality development of pharmacist-managed clinics.

Objective In order to understand the current resistance status of Aedes albopictus(Ae. albopictus) adult population to commonly used insecticides and the resistance dynamics development in Zhejiang Province and provide a theoretical basis for the scientific and rational use of hygienic insecticides. Methods Resistance determination was carried out using the diagnostic dose method(GB/T 26347-2010)recommended by WHO in the adult mosquito contact cylinder method to monitor the resistance of Ae. albopictus field populations in 11 cities and districts in Zhejiang Province in 2024. Results The monitoring result showed that adult Ae. albopictus in 11 areas were resistant or suspected resistant populations to both cis-cypermethrin and permethrin; suspected and resistant populations to the organophosphate insecticide malathion were as high as 81.82%; while suspected resistance to the carbamate insecticide residual carbofuran accounted for 45.45%, and the rest of the monitoring sites were sensitive to it. Conclusions The result suggest that the generalized resistance of Ae. albopictus populations to pyrethroids and organophosphorus insecticides in the field in Zhejiang Province needs to be highly emphasized. In future mosquito vector and mosquito-borne disease control, insecticides should be selected based on the resistance monitoring information, while following scientific guidelines for insecticide use.

Metabolic associated fatty liver disease （MAFLD） is the most prevalent chronic liver disease worldwide， and its progression is closely associated with the development of liver fibrosis， liver cirrhosis， and even hepatocellular carcinoma. However， there is still a lack of effective therapies for MAFLD in clinical practice. Telomere is the protective structure at the end of chromosomes， and telomere shortening and functional impairment have been identified as one of the key factors regulating the pathological progression of MAFLD. This article systematically reviews the core mechanism of action of telomere regulation in MAFLD， including its molecular functions in nucleotide metabolism， oxidative stress， and epigenetic regulation， as well as its pathological effect in hepatocytes and hepatic stellate cells. In addition， this article explores the clinical prospects of telomeres as biomarkers and therapeutic targets for MAFLD， in order to provide a theoretical reference for improving the precise diagnosis and treatment system of MAFLD.

A method was developed for determination of dilauryl thiodipropionate(DLTDP)in fried foods by coupling solid-phase extraction(SPE)pretreatment with reverse-phase liquid chromatography-tandem mass spectrometry(RPLC-MS/MS)detection.Samples were extracted with n-hexane as the solvent,purified using a neutral alumina SPE cartridge,and finally analyzed by RPLC-MS/MS.Quantitative analysis was performed using matrix-matched calibration curves combined with an external standard method under optimal experimental conditions.The results showed that DLTDP exhibited good linearity in the range of 2.0-50.0 μg/L,with a correlation coefficient(R2)≥0.999.The limit of detection(LOD)and the limit of quantification(LOQ)of the method were 0.15 mg/kg and 0.5 mg/kg,respectively.The mean recoveries at three fortification levels(0.5,1.0,and 200 mg/kg)in different samples ranged from 84.8%to 96.8%,with the relative standard deviations(RSDs)all less than 8.0%.The developed method was highly sensitive,accurate and reliable,and easy to operate,making it well suited for the routine quantitative analysis of DLTDP in fried foods.

At present,the drug substitutes represented by new psychoactive substances are gradually be-coming popular,leading to an increasing demand for identifying novel drugs with unknown structures in drug investigation.Nuclear magnetic resonance(NMR)spectroscopy is an important tool for ana-lyzing molecular structures.In the absence of standard substances,quantitative NMR(qNMR)can un-dertake the quantitative analysis of target substances in complex mixtures and has unique advantages in the research of new drugs and their precursor drugs.Due to the limitations of the site and mainte-nance costs,as well as relatively complex operation,high-field superconducting NMR is less com-monly applied in drug research.The desktop low-field NMR developed in recent years provides a new alternative solution.Due to the use of permanent magnets,its size is reduced,and the operation and maintenance costs are lowered.It has been widely used in various research fields.This article reviews the development of low-field NMR technology,summarizes the application of desktop low-field NMR in screening and identification of suspicious substances,rapid content determination,analysis of drug manufacturing processes and synthetic routes,and correlation traceability.It also looks forward to the prospects and development directions of this technology in drug research,aiming to provide a reference for researchers who work in analytical chemistry and drug research.

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.

Objective To investigate the antimicrobial resistance patterns of carbapenem-resistant Klebsiella pneumoniae(CRKP)strains isolated from children for better prevention,treatment,and control of CRKP infections in children.Methods A total of 182 clinical CRKP strains were collected between January 2018 and December 2020 in Hebei Children's Hospital.All CRKP strains were identified by matrix-assisted laser desorption ionization-time of flight(MALDI-TOF)mass spectrometry.The common carbapenemase genes(blaKPC,blaNDM,blaIMP,blaVIM,blaOXA-48)of CRKP isolates were studied by PCR.Multilocus sequence typing(MLST)was performed for homology analysis.Results The 182 children infected with CRKP were mainly infants(＞28 days to＜1 years),accounting for 49.45％(90/182),followed by newborns(≤28 days),accounting for 36.26％(66/182).The main source of the 182 CRKP isolates was sputum(50.55％,92/182),blood(15.93％,29/182),and urine(13.19％,24/182).The strains were mainly isolated from patients in neonatology(30.22％,55/182),general surgery(21.43％,39/182),cardiac surgery(13.19％,24/182),and intensive care unit(11.54％,21/182).Antimicrobial susceptibility testing showed that all of the 182 CRKP strains were resistant to cefepime,ceftazidime,piperacillin-tazobactam,and cefoperazone-sulbactam(100％).Overall,97.8％,71.4％,81.9％,75.8％,69.2％,and 2.7％of the strains were resistant to aztreonam,amikacin,ciprofloxacin,levofloxacin,doxycycline,and tigecycline,respectively.The prevalence of carbapenemase gene blaKPC-2 was the highest(73.63％,134/182),followed by blaNDM-5(15.38％,28/182),and blaNDM-1(11.54％,21/182).A total of 15 different sequence types(ST)were identified by MLST,of which ST11 was the most common type(72.53％,132/182),followed by ST17(11.54％,21/182).Conclusions CRKP isolates in Hebei Children's Hospital showed high level resistance to antimicrobial agents.Antimicrobial therapy should be prescribed cautiously according to the results of antimicrobial susceptibility testing to avoid the emergence of resistant strains.KPC-2-producing ST1 1 type CRKP strains may be prevalent in this hospital.Effective control measures should be taken to avoid further spread of such CRKP strains.

Extramedullary disease (EMD) is an independent prognostic factor for multiple myeloma (MM). Compared with MM without EMD, MM with EMD has different genetic characteristics, with a higher incidence of high-risk chromosomal abnormalities, more complex genomic profile, and immunophenotypic features related to adhesion molecule and chemokine expression. The mutual regulation between myeloma cells and tumor microenvironment, including changes in immune environment, deposition of extracellular matrix, abnormal expression of adhesion molecules, and autocrine secretion of myeloma cells, is involved in the extramedullary migration of myeloma cells. Various immune-targeted therapies have improved the prognosis of extramedullary MM (EMM). This article reviews the genetic characteristics of EMM, important role of tumor microenvironment, and progress of treatment.
