RESUMEN
Objective:To explore the relation among self-esteem, psychological flexibility and mental health in medical students, and to provide scientific reference for mental health education for medical students.Methods:A total of 788 medical students selected from a medical university in Chongqing City were investigated with the symptom checklist 90 (SCL-90), self-esteem scale (SES), acceptance and action questionnaire-Ⅱ (AAQ-Ⅱ), and cognitive fusion questionnaire-fusion (CFQ-F). SPSS 22.0 software was used for statistical analysis. T test, ANOVA, correlation analysis and tests for mediation effects were conducted. Results:There were significant differences in self-esteem and mental health level among medical students in gender and different grades ( t=-2.55, P<0.05; F=6.53, P<0.05). Mental health, self-esteem and psychological flexibility of medical students were correlated in pairs ( r=-0.528-0.694, P<0.01). Psychological flexibility played a partial mediation role between self-esteem and mental health of medical students, and the mediating effect accounted for 60.03% of the total effect. Conclusion:Self-esteem can directly predict the mental health of medical students, and can also indirectly affect mental health through psychological flexibility. Medical universities should carry out psychological education and promotion work with pertinence.
RESUMEN
Objective:To systematically evaluate and integrate the qualitative research of the practical experience and practical difficulties of advance care planning (ACP), so as to provide a reference for subsequent clinical nurses to better carry out ACP.Methods:PubMed, Web of Science, Embase, Cochrane Library, CINAHL, CNKI, Wanfang, VIP, Chinese Biomedical Literature Database were collected the qualitative research on the practical experience and practical difficulties of nurses′advance care planing, and the search time was the database establishment until August 1, 2022. Literature quality evaluation was conducted by the Joanna Briggs Institute (JBI) (2016), and the results were summarized using Meta integration method.Results:A total of 13 studies were included, and 39 studies were summarized into 11 new categories, forming 4 integrated results: nurses′ cognition of ACP practice, emotional experience of nurses′ ACP practice, personal factors that hinder ACP practice, and external environmental factors that hinder ACP practice.Conclusions:In ACP practice, nurses should be actively guided to have positive cognitive and emotional experience to improve their competence in ACP practice. At the same time, government departments should be united to support, integrate hospitals, society and other forces to formulate coping strategies against obstacles, so as to promote the development and practice of ACP.
RESUMEN
Objective:To systematically review the experience of nurses′ in providing home-based hospice care, so as to provide a basis for improving the quality of home-based hospice care and the nursing service system.Methods:Qualitative researches on nurses′ experience of providing home-based hospice care were retrieved from the Cochrane Library, PubMed,Web of Science, EBSCO, Medline, China National Knowledge Internet, China Biomedical Literature Database, Wanfang Database, VIP Database from inception to April 1, 2022. Adopting Joanna Briggs Institute Critical Appraisal Tool (2016) to evaluate the quality of included studies, the Meta-synthesis was used to explain and integrate the research results.Results:A total of 9 articles were included. This study extracted 23 clear results, 8 new categories, and 3 integrated results, including the significance of nurses′ acceptance of home-based hospice care; positive and negative emotions coexist when nurses provide home-based hospice care; challenges in implementing home-based hospice care.Conclusions:The development of home-based hospice care service is helpful to provide continuous care for the terminally ill patients and improve their quality of life, but at the same time, the ability of home-based hospice care of nurses should be further improved and the related policy guarantee should be perfected to promote the steady development of home-based hospice care in China.
RESUMEN
Moral distress generally exists in the nursing interns and has a far-reaching impact.

RESUMEN
Objective To study the effect of stress on the degradation rate in vitro of novel magnesium alloy bone screw. Methods A three-dimensional （3D） model of the tibia fracture was established using the reverse engineering method. Then, based on the FE model, the in vitro degradation experimental device for bone screws was designed. The stress distribution of the screw by finite element calculation was used as the in vitro experimental load, which effectively improved the accuracy and efficiency of the experiment. The experimental samples were divided into four groups. Group A was treated as control group without force application, while Groups B, C and D were subjected to 150, 250 and 350 N axial forces. The influence of different mechanical environment on the degradation rate in vitro of bone screws was investigated. Finally, combining the stress distributions with the degradation experiment results in vitro, the curve between the stress and the degradation rate in vitro of novel magnesium alloy bone screws was obtained. Results Degradation experiments in vitro showed that Group A had the lowest weight loss and hydrogen production, and the average degradation rate was (0.315±0.005) mm/a. While in the stress groups, the weight loss and hydrogen production increased gradually with the axial force increasing. The average degradation rates of Groups B, C and D were (0.379±0.006), (0.469±0.007) and (0.547±0.009) mm/a, respectively. Conclusions When the novel magnesium alloy bone screw was degraded in mechanical environment, the greater stress on the screw would cause the faster degradation rate in vitro. The obtained relationship between the maximum stress and the average degradation rate in vitro of the novel megnesium alloy bone screw provided data support and theoretical guidance for material selection, design and clinical application of magnesium alloy bone screws.
RESUMEN
Objective To determine the impact of new methods in teaching and examination on students' learning of psychiatry by increasing the proportion of objective questions in the final exam papers through examination reform, so as to help students adapt to the Practitioner Examination. Methods A total of 483 students from grade 2011&2012 were selected as research subjects. Through the comparative study of the test scores under different teaching methods before and after the examination reform, the SPSS 22.0 statistical software was used to analyze the structure, reliability, difficulty and level of differentiation of the examine papers via t tests. Results Examination papers after the reform showed an increase in difficulty in all question types; some question types also had higher levels of differentiation. Students receiving PBL-based education had higher scores compared to those under traditional teaching methods. The difference was statistically significant. Conclusion PBL teaching mode is more conducive to the mastering of knowledge points and helps students improve grades in objective questions. Medical schools should increase the use of PBL teaching reform in psychiatry courses and conduct examination reform, so as to improve the teaching effect and the passing rate of Practitioners Examination.
RESUMEN
Objective:To evaluate the implementation effects of critical illness insurance of New Cooperative Medical System(NCMS) on the occurrence rate and economic burden of major disease expenditure.Methods:Based on the peasant household data of China Family Panel Studies(CFPS) in 2014.the two-part model was applied to analyze the changes in major disease occurrence and burden after the implement of insurance.Results:NCMS critical illness insurance did not reduce the occurrence of critical disease expenditure,but signally cut down the economic burden of serious illness peasants in central and eastern China.Conclusion:The implementation effect of NCMS critical illness insurance was well in central and eastern China,but was poor in western China;the prevention and health care system of NCMS should be built,while the implementation plans and compensation level of critical illness insurance should be improved in western region.
RESUMEN
Transient ischemic attack (TIA) is an independent risk factor of stroke. About two-thirds patients with TIA will reoccur TIA or stroke. To predict the risk of stroke after the onset of TIA may identify the prognosis of patients, so as to have an intervention for the high-risk patients as early as possible. This article reviews the various risk assessment tools for stroke after TIA, in order to provide ideas for the prognostic assessment of TIA.
