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 authors developed a standard of medical safety ( adverse) events standardization management, according to the principle of medical safety (adverse) event management, domestic and abroad research results and best practices for medical safety ( adverse) events management, as well as the present specifics and practice of hospital management in China. Such a standards is designed to standardize such key points of medical safety ( adverse) event management in China, namely the definition, classification, risk prevention, reports response and continuous improvement, which serves as an icebreaker for scientific management of medical safety (adverse) events.

Objective To assess the quality of life, prevalence of depression and their influencing factors in patients with alopecia, to investigate, and to provide evidences for relevant clinical therapeutic strategies to improve patients′ quality of life. Methods A questionnaire survey was carried out in 237 patients with androgenetic alopecia or alopecia areata, and their quality of life and depression were measured using dermatology life quality index(DLQI)and center for epidemiologic studies depression scale (CES-D), respectively. Factors influencing the quality of life and depression were analyzed by analysis of variance and logistic regression analysis. Results Among 237 patients with alopecia, 218 questionnaires were eligible with the mean score of DLQI being 9.1 ± 5.4. Alopecia had a moderate effect on the quality of life in general, and 38.07%of the patients were severely affected. The mean score of CES-D was 14.8 ± 9.9, and 37.61%of the patients showed depressive tendency. The DLQI score was positively correlated with CES-D score(r=0.29, P<0.01). One-way analysis of variance(ANOVA)showed that the DLQI score was not affected by age, gender, education level or the number of visits. Multivariate logistic regression analysis revealed that the risk factors for depressive tendency in patients with alopecia were the number of visits (OR = 1.81, 95% CI: 1.21- 2.69) and DLQI score (OR = 1.08, 95% CI: 1.03- 1.13). Conclusion Alopecia not only affects the quality of life, but also mental states of patients.
