Objective:To develop an air transfer stretcher for severely injured patients,so as to meet the requirements of severely injured patients for rapid transport of aviation medical treatment.Methods:The guide rails of hatch of mainstream civil airliner models were analyzed through investigation.Based on the principles of modularization,integration and intelligence,a highly universal and portable aviation stretcher with the functions of rapid transport and life support was designed and developed.The design of the stretcher was verified through simulation analysis and calculation,as well as tests in laboratory,which should meet the requirements of the standards from China Civil Aviation Regulations(CCAR)-25.Results:The results of simulation analysis and tests of laboratory showed that the aviation transport stretcher,and the strength and stiffness of its structure reached to requirement of CCAR-25 standard,which was suit to the portable aviation evacuation of severely injured patients on civil airliners,and the rapid transfer between air and ground.It has the function of supporting life,and the aviation transport stretcher with high universality and convenience can enhance the safety and rescue capability of aviation evacuation system of medical treatment of aviation.Conclusion:The portable aviation stretcher with high-versatility that was researched and developed by this study can effectively solve the problems of life support,injury monitoring,and emergently rescue and treatment during the transport for severely injured patients,which improve the support ability of air-ground transportation for severely injured patients.

The air-ground transfer device for patients with serious injury is one kind of medical equipment and system that can realize the safe and efficient transfer for patients with serious injury between the air and the ground under scenarios of emergency medical rescue,which plays an important role in the process of aviation rescue.At present,a variety of air-to-ground transport devices for patients with serious injury have been developed abroad,such as the trauma life support and transportation system of United States,the medical transport aircraft of Israel and so on.In China,it has also been developed,such as general-purpose airborne stretcher supports,life support system for patients with serious injury in moving,cross-platform and etc..However,there are still many challenges in current research and development of air-to-ground transfer devices,including technical stability,intelligent level,the application of new materials and so on.Based on this,this paper systematically reviewed the domestic and international development status of air-to-ground transport devices for patients with serious injury,and analyzed the facing problems and technical challenges of these devices,and discussed their development trends in future.Through the research and analysis for existing devices,this study aimed to provide references for the research and development of air-to-ground transport devices for patients with serious injury,so as to improve the efficiency and quality of emergency medical rescue.

BACKGROUND: Spicy food consumption has been reported to be inversely associated with mortality from multiple diseases. However, the effect of spicy food intake on the incidence of vascular diseases in the Chinese population remains unclear. This study was conducted to explore this association. METHODS: This study was performed using the large-scale China Kadoorie Biobank (CKB) prospective cohort of 486,335 participants. The primary outcomes were vascular disease, ischemic heart disease (IHD), major coronary events (MCEs), cerebrovascular disease, stroke, and non-stroke cerebrovascular disease. A Cox proportional hazards regression model was used to assess the association between spicy food consumption and incident vascular diseases. Subgroup analysis was also performed to evaluate the heterogeneity of the association between spicy food consumption and the risk of vascular disease stratified by several basic characteristics. In addition, the joint effects of spicy food consumption and the healthy lifestyle score on the risk of vascular disease were also evaluated, and sensitivity analyses were performed to assess the reliability of the association results. RESULTS: During a median follow-up time of 12.1 years, a total of 136,125 patients with vascular disease, 46,689 patients with IHD, 10,097 patients with MCEs, 80,114 patients with cerebrovascular disease, 56,726 patients with stroke, and 40,098 patients with non-stroke cerebrovascular disease were identified. Participants who consumed spicy food 1-2 days/week (hazard ratio [HR] = 0.95, 95% confidence interval [95% CI] = [0.93, 0.97], P <0.001), 3-5 days/week (HR = 0.96, 95% CI = [0.94, 0.99], P = 0.003), and 6-7 days/week (HR = 0.97, 95% CI = [0.95, 0.99], P = 0.002) had a significantly lower risk of vascular disease than those who consumed spicy food less than once a week ( Ptrend <0.001), especially in those who were younger and living in rural areas. Notably, the disease-based subgroup analysis indicated that the inverse associations remained in IHD ( Ptrend = 0.011) and MCEs ( Ptrend = 0.002) risk. Intriguingly, there was an interaction effect between spicy food consumption and the healthy lifestyle score on the risk of IHD ( Pinteraction = 0.037). CONCLUSIONS Our findings support an inverse association between spicy food consumption and vascular disease in the Chinese population, which may provide additional dietary guidance for the prevention of vascular diseases.

Objective:Pediatric chronic sinusitis （CRS） is a common disease within the field of otolaryngology-head and neck surgery. Due to the immaturity of sinus development and immune competence in children, its etiology and pathophysiology are complex, and its clinical features and outcomes differ significantly from those in adult patients. Currently, there are issues in the diagnosis and treatment of pediatric CRS, particularly in areas such as antibiotic use and surgical interventions, owing to a lack of sufficient attention. In recognition of this, the Chinese Rhinopathy Research Cooperation Group developed this expert consensus based on a systematic review of the latest literatures from both domestic and international sources, with reference to the latest evidence-based medical evidence worldwide, and in combination with their own clinical experience. The consensus covers various aspects including epidemiology, predisposing factors, pathophysiology, diagnosis and differential diagnosis, as well as treatment strategies such as medical therapy and surgical intervention. It aims to standardize the clinical diagnosis and treatment of pediatric CRS, improve clinical efficacy and patient satisfaction, reduce clinical expenditures, and decrease the occurrence of adverse reactions.
