The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.

Objective:To analyze the current situation of professional identity of nursing students in China, and explore the research hotspots and development trends.Methods:We searched relevant articles in China National Knowledge Infrastructure, VIP and WanFang Data, and the retrieval time limit was from January 1, 2006 to December 31, 2021. CiteSpace software (version 5.8. R2) was used for bibliometric and visual analysis of the number of articles, authors, institutions and keywords.Results:Since 2016, the number of articles increased significantly. At present, there were large numbers of cross-sectional studies, but there were some limitations and lack of longitudinal studies. There was much cooperation between authors and little cooperation between research institutions, and no large-scale cooperation network was formed. The keyword emergence analysis found that the research on nursing students' professional identity and clinical practice had the longest emergence time, and the keyword with the highest emergence in 2020 was "COVID-19".Conclusions:At present, it is a critical period for the development direction of nursing students' professional identity research to change. It is necessary to establish a large cooperation network model, carry out longitudinal investigation and intervention research, so as to improve nursing students' professional identity.

Objective:To explore whether health and wellness coaching can promote healthy lifestyle among highrisk people with stroke.Methods:The highrisk people with stroke admitted to the hospital were randomly divided into a test group (49) and a control group (49) by excel random function method.The control group was given telephone health education once a week, a total of 12 times last 3 months; On this basis, the test group carried out from every week to every months,a total of 8 timeshealth and wellness coaching, measuring the health promotion lifestyle (HPLP-Ⅱ) scale scores of the two groups of subjects at baseline, at the end of the intervention, and 3 months after the end of the intervention.Results:There was no statistical difference in the general demographic data of the two groups of subjects. Repeated measures analysis of variance showed that three months after the intervention, the two groups of subjects had statistically significant differences in nutrition, health responsibilities, physical activity, self-actualization, and health promotion lifestyle scores between the groups, time, and interaction ( F values were 12.131-502.649, P<0.01). There were no statistical differences in interpersonal relationship and stress coping dimensions ( P>0.05). Simple effect analysis found that at the end of the intervention, the two groups of subjects had only statistical differences between the self-actualization dimension and the total score of health promotion lifestyle ( P<0.01). Three months after the end of the intervention, the total scores of nutrition, health responsibilities, sports, self-actualization and health-promoting lifestyles of the two groups of study subjects were significantly different ( P<0.01). Conclusions:Health and wellness coaching can promote healthy lifestyle among highrisk people with stroke.

Ego-depletion is a phenomenon in which an individual's cognitive, emotional and behavioral control ability or willingness declines after long-term self-control. Patients with chronic diseases need to change their lifestyles for a long time, understand and master the knowledge of the disease, and they are prone to self-depletion after diagnosis. This paper summarized the research progress of ego-depletion in patients with chronic diseases through the concept of ego-depletion, subjective measurement tools, and the current research status of ego-depletion in patients with chronic diseases, and provided inspiration for future research directions, with a view to providing ideas for further research on ego-depletion in patients with chronic diseases.

Objective:To explore the application effect of online teaching supervision in nursing teaching quality of undergraduate nursing students.Methods:Using the convenient sampling method, the 2017 (September 2019 to January 2020) and 2018 (March to July 2020) undergraduate nursing students from the School of Nursing of Harbin Medical University were selected as the research objects. The 2018 undergraduate nursing students were included in the online live teaching group ( n=80) , and the 2017 undergraduate nursing students were included in the offline teaching group ( n=76) . A total of 10 supervisors were selected to evaluate the teaching quality of teachers' online and offline classes through the Multiple Comprehensive Evaluation Tables. The results of the final examination of nursing students in the two groups were used to evaluate the effect of the online live teaching form. The teaching satisfaction with the online live teaching method of nursing students in the two groups was compared. Results:The online teaching scored (95.05±2.14) on the Multiple Comprehensive Evaluation Tables, which was higher than that of the offline teaching (90.05±0.96) , and the difference was statistically significant ( t=6.745, P<0.01) . There were no statistically significant differences in the final exam scores of nursing students in the two groups and their satisfaction with online live teaching methods ( P>0.05) . Conclusions:The practice form of online classroom teaching supervision can effectively ensure the teaching quality and teaching effect of teachers and ensure the teaching satisfaction of nursing students with online live teaching.
