Ischemic stroke is a complex cerebrovascular disorder characterized by highly unpredictable outcomes influenced by patient-specific variables, including age, stroke severity, and preventable stroke-related complications such as infections. Analyses of clinical data have indicated a cumulative post-stroke infection rate of approximately 30%, with reported rates ranging from 5% to 65%. Post-stroke infections pose a significant challenge, as they not only increase the financial burden of stroke care but are also associated with adverse clinical outcomes, prolonged hospital stays, and a higher risk of stroke recurrence. The inflammatory response plays a pivotal role in the pathophysiology of ischemic stroke, encompassing the activation of inflammatory cells, the release of inflammatory mediators, and the engagement of inflammatory signaling pathways. Recent advances in molecular biology have facilitated the identification and investigation of numerous inflammation-related biomarkers. This article reviews the roles and mechanisms of key inflammatory biomarkers, including cytokines, chemokines, adhesion molecules, inflammation-related enzymes and mediators, receptors, signaling pathway molecules, and acute-phase proteins in the context of ischemic stroke, highlighting their significance in stroke pathophysiology and prognostic assessment. Additionally, in conjunction with the latest research advances, the article discusses novel biomarkers such as microRNAs and galectin-3, which are emerging as important tools in multiple domains, including diagnosis and treatment. Drawing on clinical diagnostic and therapeutic practices, this review analyzes the diagnostic and therapeutic roles of both novel and traditional biomarkers in the progression of ischemic stroke, following the temporal sequence from disease onset to prognosis. Finally, the article addresses the limitations of current research and offers perspectives on future directions, providing insights that may contribute to the advancement of precision medicine in the management of ischemic stroke.

Hepatocellular carcinoma (HCC) is the most common subtype of primary liver cancer and continues to be a major cause of cancer-related mortality, particularly in regions of China with a high hepatitis B virus prevalence. Early-stage diagnosis remains challenging due to its asymptomatic onset and the limited sensitivity of conventional biomarkers, which together contribute to delayed detection, suboptimal therapeutic outcomes, and poor prognosis. These limitations underscore the urgent need for reliable, sensitive, and specific biomarkers to enable timely detection and targeted intervention. Protein induced by vitamin K absence or antagonist-II, an abnormal prothrombin variant generated under vitamin K deficiency or antagonism, has emerged as a promising candidate with diagnostic and therapeutic relevance in HCC. This review critically examines the molecular and biological characteristics of protein induced by vitamin K absence or antagonist-II, evaluates its clinical utility in HCC diagnosis and management, and delineates the current limitations hindering its broader application. Furthermore, future perspectives are proposed to guide translational research and clinical implementation. Collectively, this review aims to provide a comprehensive theoretical framework to advance precision diagnosis and individualized treatment strategies for HCC.

Laboratory-acquired infections (LAIs) have been documented since the first report of typhoid fever in 1885 and continue to endanger laboratory professionals despite decades of biosafety advances. This review provides a comprehensive overview of LAIs, emphasizing their history, modes of transmission, and strategies for prevention.

A systematic review of historical records, case series, and biosafety guidance (1885–2025) identified documented LAIs, their transmission routes, and preventive measures. Data were extracted on pathogen spectrum, geographic distribution, incident outcomes, and the effectiveness of biosafety interventions.

Historical analysis identified 50 laboratory-acquired typhoid infections with six deaths from 1885 to 1915, largely due to mouth pipetting and aerosol exposure. A sharp decline in fatal bacterial infections was observed following the introduction of Class II biosafety cabinets in the 1960s. From 2000 to 2021, 309 LAIs were reported across 94 studies, most commonly Salmonella enterica (56.6%), vaccinia virus (4.2%), and Brucella species (3.9%), with Brucella responsible for over half of hospital-laboratory cases (60 per 100,000 personnel-years). In Canada during 2023, 63 exposure events occurred, including three confirmed infections despite adherence to biosafety level protocols. Environmental persistence studies underscored surface-borne risks. The most effective preventative measures included abolishing mouth pipetting, mandatory use of gloves and eye/face protection, routine Class II biosafety cabinet use for aerosol-generating procedures, surface disinfection with 0.5% sodium hypochlorite, and annual competency-based biosafety training with incident reporting.

LAIs remain geographically widespread and pathogen-diverse. Quantitative historical trends and contemporary surveillance highlight critical transmission routes, including ingestion, inoculation, mucosal splash, and inhalation, while reinforcing evidence-based prevention strategies. Sustained investment in biosafety infrastructure, real-time exposure reporting, and pathogen-specific training is essential to further reduce LAI incidence and severity in the face of emerging antimicrobial resistance and novel agents.

Craniopharyngioma (CP), although histologically benign, is a surgically challenging sellar-region tumor for which stereotactic irradiation is increasingly used as an alternative or adjuvant strategy. This review summarizes the role of stereotactic radiosurgery (SRS) in managing CP, with a focus on treatment outcomes, technical advances, and emerging strategies to support evidence-based clinical practice. Literature reports indicate that Gamma Knife radiosurgery achieves variable tumor control rates (36–100%), with optimal outcomes (79.6–91.4%) when marginal doses ≥12 Gy are delivered and patients receive adequate follow-up. Smaller tumors (<5 cm3) and those with higher solid components show particularly favorable outcomes. SRS demonstrates a favorable safety profile, with visual impairment occurring in approximately 4% of cases and endocrine dysfunction in 6%. Compared to conventional radiotherapy, SRS significantly reduces the risk of hypothalamic obesity in pediatric patients. The identification of BRAF mutations in papillary CPs has created novel opportunities for combining targeted therapies with SRS. Collectively, these advances underscore the role of SRS as an essential component of multidisciplinary CP management, particularly in the treatment of residual or recurrent lesions. It offers a more favorable toxicity profile and may improve quality of life outcomes compared to conventional radiotherapy. Further studies are needed to optimize patient selection, dosing strategies, and integration with novel systemic therapies.
