Objective:To design and develop a battlefield first-aid simulated training system, to evaluate the application effect of the system through a quasi-experimental controlled trial, and to provide training means to support the enhancement of Chinese army's first-line treatment capability.Methods:A battlefield first-aid simulated training system was designed and developed with the guidance of the theory of "experiential learning cycle". From March to June 2023, 108 health sergeants who participated in non-academic education training from a military medical university were recruited to a quasi-experimental controlled trial and randomly divided into a control group and an experimental group, with 54 sergeants each. The control group was trained using traditional face-to-face simulation training, and the experimental group was trained using the Battlefield First-aid Simulated Training System. The differences in effects of computer simulation training and traditional face-to-face simulation training were compared, with the primary evaluation indices being the first-aid knowledge level and inferential capability of rescue on the battlefield, and the secondary evaluation indices being the self-perception and training satisfaction. The SPSS 26.0 software was used for conducting the t test, chi-square test or Fisher's exact probability test, and non-parametric test. Results:All 108 subjects completed the training and had an improvement in the knowledge level, self-perception, and inferential capability of rescue after the training ( P<0.001). The difference in the degree of improvement in the knowledge level [(19.93±8.98) vs. (16.55±10.10)] and self-perception [10.50 (7.00, 13.25) vs. 10.00 (7.00, 12.50)] was not statistically significant between the experimental group and the control group ( P>0.05), but the degree of improvement in the inferential capability of rescue of the experimental group [6.00 (5.00, 9.25)] was significantly lower than that of the control group [8.00 (7.00, 11.00)] ( P<0.05). There was no significant difference in the training satisfaction scores between the two groups ( P>0.05). Conclusions:The system has a similar training effect to traditional face-to-face simulation training, but shows a slight deficiency in the improvement in the inferential capability of rescue. It serves as a recommended training resource and format from battlefield first-aid theory learning to practical application. The system still needs to be optimized and improved in the aspects of functionality, simulation, and intellectualization in the future.

Based on the sampling survey data of 11 164 medical researchers in China, this paper analyzed the understanding, attitude and compliance of medical researchers on scientific research ethics in China. The survey found that although most medical researchers claim to have more understanding of scientific research ethics, the level of understanding of scientific research ethics is not optimistic; the channels to scientific research ethics knowledge are diversified, but the standardized training channels are insufficient; most researchers held the positive attitude toward following the ethical norms, but those male, youth under 35, with senior professional titles, or from northeast China held negative attitude relatively; more than half of the researchers claimed that the supervision of research ethics in China was basically in place, but some people said that the violation of scientific research ethics was common, and some researchers reported that there was a phenomenon of "direct seal consent and reply" in ethical review. Compared with medical institutions, enterprises and universities are the weak links of scientific research ethics training, education and review. Based on the above actuality, it puts forward policy suggestions to strengthen the scientific research ethics training and ethics review requirements.

Objective:To develop a systematic and comprehensive training program focusing on infectious disease emergencies, which is suitable for continuing education of medical staff.Methods:The emergency competence index system constructed in previous study was used as the content framework. The training method was selected based on the core concept of "Lindeman's View of Adult Education". The training form was designed based on the results of the questionnaire survey. The expert group meeting was used to demonstrate and revise the concrete training items.Results:The finally formed Training Program on Infectious Diseases Emergencies for Medical Staff adopted a "small-group" training format and modular design, including a total of 3 modules and 9 items, and the training program database included portable training manuals, skills videos, scenario cases scripts, and assessment papers, etc.Conclusion:The developed training program could be applied to regular continuing education or intensive training of response team for certain infectious disease emergencies, so as to improve their response competence.

【Objective】 To summarize a rapid and effective method to eliminate autoantibodies interference with blood group identification and evaluate its treatment effect. 【Methods】 Blood samples with suspicious results in initial blood group identification were collected, and those caused by autoantibodies were chosen, and their red blood cells were washed, dispersed or treated with sulfhydryl reagent. After allogeneic or autologous absorption of plasma, blood groups of those patients were re-detected to evaluate the effectiveness of the above method. 【Results】 Among 39 patients presenting suspicious ABO blood group, 9 were interfered by autoantibodies. After appropriate treatment, the ABO/RhD blood group of those patients could be identified. 【Conclusion】 Autoantibodies could interfere the identification of ABO/RhD blood group, and the efficiency and accuracy of blood group identification could be improved by analyzing the test results and selecting appropriate treatment methods.

Objective:To apply the standardized wounded soldier (SWS) grading evaluation indicator system in naval troops and naval colleges of China respectively to test its effectiveness.Methods:A total of 30 soldiers from 15 naval troops were trained as basic-level SWS, and 6 students from a naval college were trained as professional-level SWS. The indicator system was verified in the form of knowledge questionnaire and quality report. Convenience sampling was used to select medics, instructors and SWS as subjects for evaluation.Results:The reliability, discrimination and difficulty of the knowledge questionnaire were good, and the reliability and validity of quality report were good. The general evaluation of the professional-level SWS was better than that of the basic-level SWS.Conclusion:SWS grading evaluation indicator system is suitable and feasible for reasonably evaluating the simulation quality of SWS and stepping up CPLA military training in real combat condition, and is conducive to promoting the popularization and application of SWS in military medical simulation training.
