Platelets are small, anucleated cells generated by cytoplasmic fragmentation and shedding from mature megakaryocytes. Upon vascular stimulation or injury, platelets become activated and adhere to exposed vascular endothelial cells, ultimately forming thrombi to promote blood coagulation and wound healing. In recent years, increasing evidence from in-depth studies on platelet function has revealed that autophagy plays a crucial role in platelet production and functional performance. Autophagy is an intracellular process of material recycling and reuse, involving autophagosome formation, cargo degradation, and nutrient recycling, which facilitates the maintenance of homeostasis and defense against pathogen infection. Numerous studies have demonstrated that autophagy participates in the regulation of platelet production, activation, and aggregation, and is closely implicated in the pathogenesis of platelet dysfunction-related diseases such as immune thrombocytopenia. Additionally, platelet-rich plasma therapy, by modulating the autophagic process, has shown great potential in treating osteoarthritis and promoting diabetic foot wound healing. This review thoroughly explores the potential roles of autophagy in regulating platelet production and function, as well as in platelet-related diseases. Future research should focus on the molecular mechanisms of platelet autophagy, investigate its dynamic changes under different disease conditions, and explore how autophagy modulation can improve platelet function and treat related diseases. This will provide a theoretical foundation for developing novel therapeutic strategies and is expected to bring breakthroughs in the treatment of platelet-related diseases.

Hypertension ranks among the most prevalent chronic non-communicable diseases worldwide, with its prevalence rising steadily and exerting substantial impacts on the demographic composition of voluntary blood donors and the safety of blood supply. The eligibility of hypertensive individuals for safe blood donation and the relevant screening and management strategies have long remained controversial in transfusion medicine. This article systematically reviews the epidemiological characteristics of hypertension, donation-related physiological alterations and underlying risk mechanisms. By synthesizing evidence from international multicenter studies and regulatory practices across major nations, it conducts a comprehensive analysis of blood donation safety and donor admission criteria for hypertensive patients. Available evidence demonstrates that for hypertensives with well-stabilized blood pressure and no severe cardiac, cerebral or renal complications or target organ damage, the overall incidence of adverse reactions following blood donation is comparable to that in healthy donors, and no definitive correlation has been identified between blood pressure levels and vasovagal responses. Current mainstream international management frameworks are gradually shifting from screening reliant on a single blood pressure cutoff value toward an integrated strategy combining stratified risk classification and individualized dynamic assessment, with core focus on long-term blood pressure control, consistency of medication regimens and complication status. Meanwhile, emerging technologies including artificial intelligence, ambulatory blood pressure monitoring and wearable devices have opened innovative avenues for blood donation risk evaluation and full-cycle donor management. In light of existing clinical evidence, future efforts should further refine the multi-dimensional risk stratification system, facilitate the implementation of intelligent screening and continuous monitoring technologies, and scale up health education and follow-up management for hypertensive populations. Such measures aim to appropriately expand the pool of eligible blood donors while safeguarding donation safety, ultimately achieving coordinated improvement in blood safety and blood supply capacity.

Objective This study aims to develop and evaluate an emergency medical information management system for the medical rescue of mass casualties in public health emergencies at civil airports,focusing on on-site triage and emergency treatment.Methods A retrospective analysis was conducted to compare the effects of on-site emergency drills for mass-casualty rescue in public health emergencies at the Guangzhou Baiyun International Airport Emergency Center in 2018 and 2024.The 2018 drills involving 21 casualties for which conventional emergency medical rescue equipment and procedures were utilized were set as a control group,while the 2024 drills involving 19 casualties for which an emergency medical information processing system were set as an experimental group.Data were analyzed using descriptive epidemiology,chi-square test,and t-test in terms of in-jury conditions,triage time,and total transfer and handover time.By integrating the entire process and all elements to achieve in-formation-based handling in the practical emergency medical rescue drills,the role and advantages of the emergency medical in-formation processing system in scientific command,rapid response,rapid triage,and emergency treatment for mass casualties in public health emergencies were examined.Results The two drills had no difference in the number of casualties(x2=0.054,P=0.973).The time spent on casualty triage and the total time for transfer and handover in 2024 were significantly reduced com-pared with those in 2018(t′=18.992,14.787,both P＜0.001).Conclusion The emergency medical information management system enhances the command,response capabilities and rescue efficiency and level of emergency medical rescue of mass casual-ties in public health emergencies at civil airports.It has promoted the informatization,digitalization and intelligence construction of emergency medical rescue for public health emergencies at civil airports in China,thereby offering a reference for optimizing the informatization model of emergency medical rescue at civil airports in China.
