Objective:To explore the factors influencing the supportive communication ability of medical undergraduates, and to propose strategies to improve supportive communication.Methods:By cluster sampling, we selected 388 medical undergraduates of grades 2017 and 2018 from Harbin Medical University for a questionnaire survey on supportive communication, general self-efficacy, and health education abilities. SPSS 22.0 was used for descriptive statistical analysis. AMOS 22.0 was used to construct a structural equation model to verify the relationship between the three variables. Mediating effects were also tested.Results:The students showed good supportive communication ability, with a total score of (74.28±10.84) points. The general self-efficacy score was (27.81±5.58) points, and the total score of health education ability was (25.50±4.76) points. General self-efficacy had direct positive effects on supportive communication and health education abilities ( β=0.75, 0.31, both P<0.001). Health education ability had a direct positive effect on supportive communication ability ( β=0.14, P<0.001). Health education ability played a significant mediating role in the influence of general self-efficacy on supportive communication ability (standardized mediating effect value=0.042, P<0.01), with the mediating effect accounting for 5.1%. Conclusions:The health education competency of medical undergraduates can mediate the effect of general self-efficacy on supportive communication ability. By strengthening medical humanities education to increase general self-efficacy and also emphasizing the cultivation of health education competency, the supportive communication ability of students can be improved.

In this regard, the research group proposed countermeasures to change online teaching concept, reform online teaching methods, improve the function of online teaching platform, and optimize online course resources in order to timely summarize the online teaching situation, improve the shortcomings and promote advanced experience, and ensure the quality of follow-up online teaching.

Objective:To analyze the worldwide development status and frontier hotspots in the field of critical care nutrition in recent 10 years, and to inform domestic future research direction.Methods:Publications on critical care nutrition researches between January 1, 2012 and December 31, 2021 were retrieved from Web of Science core database. CiteSpace and VOSviewer were used for visual analysis.Results:After screening, a total of 2,467 articles were included, with an overall increasing trend in the number of publications. A total of 11,301 authors devoted to critical care nutrition researches, among whom Daren K. Heyland (81) published the most globally and Academician Jieshou Li (9) published the most in China. The United States (812), China (221) and Canada (206) were the top 3 countries concerning numbers of publications in this field. The main research institutions were Harvard University, Queen's University and University of Leuven while Nanjing University ranked the highest domestically. Journal of Parenteral and Enteral Nutrition, Nutrition in Clinical Practice and Clinical Nutrition were the three most active journals in this field. Cluster analysis of keywords identified 11 representative cluster labels. Global focuses in critical care nutrition were influence of malnutrition, nutritional treatment pattern and energy and protein supplementation. Special interests were in the nutrition therapy in newborns, obese population and sepsis patients as well as intestinal microbial flora and coronavirus disease 2019.Conclusions:Critical care nutrition research is still under rapid development. Close collaboration between domestic core research circles and institutions should be emphasized while promoting international interactions. Researches on key issues such as energy and protein supplementation should be encouraged, so as to provide stronger evidence for better diagnosis and treatment standards in critical care nutrition.

Objective:To analyze the use of policy tools for rural-oriented tuition-waived medical student training policy and to provide relevant suggestions for the continuous promotion of the policy.Methods:With "rural-oriented tuition-waived medical students" as the key word, the policy texts were collected and screened from government portals. Using ROTHWELL disaggregated method to build the rural order directional medical students training policy analysis framework, applying Excel 2019 software for classification and coding of policy texts.Results:A total of 13 rural-oriented medical student training policy texts were screened and obtained. The X dimension of the policy analysis framework for rural order-oriented medical student training included three policy tools, namely, supply, environment and demand, and the Y dimension included three policy objectives, namely, available, usable, and retained. In X dimension, environmental policy tools were most frequently used. In Y dimension, the "retained" target had the highest frequency of use.Conclusion:There were differences in the frequency of using policy tools for targeted medical student cultivation in different policies. The frequency of using environmental tools is higher, which highlighted the attention of the state to medical and health services. The internal structure of policy tools is unbalanced, so the configuration of supply-oriented policy tools should be optimized, and the construction of demand-oriented policy tools should be emphasized. It is suggested to continuously optimize the combination of policy tools, improve the compatibility between policy tools and rural order-oriented medical student training, and pay attention to the sustainability of policy tools.

Objective:To investigate the impact of achievement goals on the academic achievement of medical students.Methods:In May to June of 2019, an online questionnaire survey was performed for data collection, and the stratified sampling method was used for sampling. Demographic factors, Achievement Goal Scale, and Academic Achievement Scale were used in this study, and descriptive statistics, the Pearson correlation analysis, and the multivariate linear hierarchical regression analysis were performed to analyze the impact of achievement goals on the academic achievement of medical students.Results:For these medical students, the mean value of achievement-near to the goal orientation was (3.45±0.77), the mean value of achievement-dodge the goal orientation was (3.43±0.80), and the mean value of mastery goal orientation was (3.85±0.66). Achievement-near to the goal orientation had a significant positive impact on academic achievement ( β=0.336, P<0.01), and mastery goal orientation also had a significant positive impact on academic achievement ( β=0.540, P<0.01). Conclusion:The achievement goals dominated by mastery goal orientation is the most beneficial dimension for the development of medical students.

Objective:To investigate the current situation of students' academic procrastination behavior in medical colleges and universities and its influencing factors, and to put forward suggestions to reduce the academic procrastination of medical students.Methods:A total of 1 327 undergraduate students from three medical colleges and universities in Heilongjiang Province were randomly selected to receive questionnaire investigation on life satisfaction, anxiety, and academic procrastination. SPSS 23.0 was used for data analysis.Results:①The total procrastination scores of medical students were (35.00±8.92) points. ②There were statistical differences in the academic procrastination of medical students with different genders, whether the only children, the reasons for choosing the major, and the level of achievement ( P < 0.05). There was no statistical difference in academic procrastination among medical students of different ages and grades ( P > 0.05). ③Medical students' procrastination was positively correlated with their anxiety level ( r = 0.102, P < 0.01), and negatively correlated with life satisfaction ( r = -0.117, P < 0.01). ④Regression analysis showed that the following six predictive variables including the level of achievement, gender, life satisfaction, anxiety, reasons for choosing the major, and whether the only children could effectively explain the variance of 14.2% academic procrastination of medical students. Conclusion:The overall degree of academic procrastination of medical students is higher than that of non-medical students. And the students' achievement level, gender, life satisfaction, anxiety, the reasons for choosing this major and whether the only child are the influencing factors of academic procrastination.

Objective:To investigate the current situation of general practitioners' occupational pressure in Heilongjiang Province, and explore its relationship with professional identity and perceived organizational support. It aims to provide references for the construction of general practitioners and the development of general medical education.Methods:The general situation questionnaire, perceived organizational support scale, occupational pressure scale, and professional identity scale were applied through network and site surveys for collecting data. A total of 288 questionnaires were collected with 263 valid questionnaires (91.3%). Pearson correction analysis and bootstrap analysis were performed for data analysis.Results:The average score of occupational pressure among general practitioners was (115.95±22.40), and the results of Pearson correction analysis showed that perceived organizational support was negatively correlated with occupational pressure ( r=-0.413, P<0.01) and positive correlation with professional identity ( r=0.587, P<0.01). There were also significant negative correlations between professional identity and occupational pressure ( r=-0.442, P<0.01). Moreover, the mediating effect showed that professional identity had a certain mediating effect on the relationship between perceived organizational support and occupational pressure (LLCI=-0.2039, ULCI=-0.0760, P<0.05). Conclusion:General practitioners' occupational pressure was at a high level, which can be reduced through improving the perceived organizational support and professional identity.

Medical curriculum integration is of great significance for reforming traditional medical education models and cultivating new medical talents with competency. On the basis of reviewing the concepts and development history of medical curriculum integration in China, this article sorts out three relatively mature medical curriculum integration models based on the practice of medical education reform in China, namely, organ-system-based curriculum model, and problem-based curriculum model and modular curriculum integration model. It also points out the difficulties of the current curriculum integration reform in medical colleges and universities from the aspects of the construction of teaching staff, the construction of integrated curriculum teaching materials, the design and connection of curriculum, and the assessment and evaluation. Finally, we should deeply analyze the concept of curriculum integration and create a curriculum model suitable for the reality of China's medical education in practice, hoping to provide reference for the practice of medical curriculum integration reform in China.

Long non-coding RNAs (lncRNAs) regulate various biological processes ranging from gene expression to animal behavior. Although protein-coding genes, microRNAs, and neuropep-tides play important roles in the regulation of phenotypic plasticity in migratory locust, empirical studies on the function of lncRNAs in this process remain limited. Here, we applied high-throughput RNA-seq to compare the expression patterns of lncRNAs and mRNAs in the time course of locust phase change. We found that lncRNAs responded more rapidly at the early stages of phase transition. Functional annotations demonstrated that early changed lncRNAs employed different pathways in isolation and crowding phases to cope with changes in the population density. Two overlapping hub lncRNA loci in the crowding and isolation networks were screened for func-tional verification. One of them, LNC1010057, was validated as a potential regulator of locust phase change. This work offers insights into the molecular mechanism underlying locust phase change and expands the scope of lncRNA functions in animal behavior.
