Objectives: To explore the effect of comfort nursing on joint function, pain degree and Baird score after minimally invasive ankle fracture. METHODS: A total of 62 patients with minimally invasive fracture of ankle joint treated in our hospital from July 2019 to July 2020 were selected as the research subjects. According to random number method, all patients were divided into observation group and control group, with 31 cases in each group. Conventional nursing intervention was carried out in the control group and comfort nursing intervention was given in the observation group. After surgery, the recovery of bare joint function was compared between the two groups. Pain scale (VAS) was used to evaluate the degree of pain in the two groups, the Hamilton Anxiety Scale (HAMA) was used to assess patients' anxiety levels, and the comparison was made before, 3 months and 6 months after surgery. The postoperative Baird scores of the two groups were compared. The incidence of postoperative complications between the two groups was statistically analyzed and compared. The nursing satisfaction of the two groups of patients was compared. RESULTS: Compared with the control group, the number of excellent and good cases in observation group was significantly increased (P<0.05), while the number of poor cases was significantly decreased (P<0.05). There was no significant difference in the degree of pain and anxiety between the two groups before operation (P>0.05). Compared with preoperation, the pain degree, body anxiety degree and mental anxiety degree in 2 groups at 3 and 6 months after operation were significantly decreased (P<0.05); The pain score, somatic anxiety score and mental anxiety score of the observation group were significantly lower than those of the control group at 3 and 6 months after surgery (P<0.05); The pain scores of observation group at 3 months and 6 months after surgery were significantly lower than those of control group (P<0.05). Compared with the control group, the postoperative Baird score in observation group was significantly increased (P<0.05); The incidence of pressure sores, wound infection and complications of lower extremity deep vein thrombosis in the observation group was significantly lower than that in the control group (P<0.05). Compared with the control group, the nursing satisfaction of the observation group was significantly increased (P<0.05). Conclusion: The postoperative nursing of patients with minimally invasive fracture of ankle joint, taking comfortable nursing can effectively improve the joint function and nursing satisfaction of patients, relieve thepain of patients, improve their prognosis, has certain advantages, worthy of further clinical promotion and application.

After the reform and opening up, the speed of changes in China's rural areas is extremely rare in the history of China and even the world. The rapid development of China's economy leads this process of change. During this period, the speed of China's development caused great changes in ethnic identity, physical space, and cultural structure of traditional villages. On the whole, these changes were made passively along with the economic development of the entire country's large-scale system. Such passive village changes are mainly positive, but there are also negative aspects. Excessive reliance on exogenous economic forces can easily lead to lower uniqueness of the village’s culture, which is unconducive to the sustainable development of the village. Therefore, traditional Chinese villages should be developed based on the differences between urban and rural areas and the uniqueness of specific villages. This can not only meet the economic development needs of the village, but also achieve cultural diversity inheritance of traditional Chinese villages, thereby avoiding the continuous destruction and damage of the unique culture of specific villages in economic development.

Using literature research methods, analysis and comparison, and using the multidisciplinary theoretical knowledge of culturology and sociology, and guided by the school's inheritance and promotion of China's excellent traditional sports culture, the school makes a theoretical analysis on the value and path of the inheritance of China's excellent traditional sports culture. The results show that Chinese excellent traditional sports culture can cultivate students' cultural self-confidence and realize cultural power, awaken students' collective memory and enhance their patriotic consciousness; it is of great educational value to improve students' physical and mental health and help build a healthy China. Conclusion and suggestion: The inheritance of Chinese excellent traditional sports culture in school should focus on the construction of school education environment, improve the training system of sports talents, strengthen the construction of traditional sports characteristic courses and the development of teaching materials, and enhance the educational and cultural functions of fostering character and civic virtue, so as to provide a solid theoretical basis for the development of Chinese school sports and the great rejuvenation of the Chinese nation in the new era.

Objectives: To investigate the psychological state of front-line medical staff during the prevention and control of COVID-19, in order to provide effective psychological support and social intervention, and to provide reference ideas. Methods The research method was a cross-sectional research method. The convenience sampling method was adopted to select 156 first-line medical staff during the prevention and control period of the COVID-19. The online survey scale developed by the "Questionnaire Star" was used to investigate the psychological state of the first-line medical staff. Results There were significant differences in the overall status of depression, anxiety, and stress among front-line medical staff in terms of gender, education level, professional title status, children’s status, and working years (P<0.05); among the five dimensions of mental state, the fear and worry dimension scored the highest. The overall confidence dimension score was the lowest (P<0.05). According to Pearson correlation analysis, the overall confidence of front-line medical staff is related to the dimensions of fear and worry, hospital support, and psychological support (P<0.05); while fear and worry are mainly related to hospital support and psychological support (P<0.05). Front-line medical staff all have different degrees of depression and anxiety. The incidence of depression is 71.15%, and the incidence of depression is 30.77%. The incidence of anxiety is 74.36%, and the incidence of anxiety is 58.97%. Conclusion During the prevention and control of COVID-19, the psychological conditions of front-line medical staff are worrying. Therefore, it is advisable to formulate corresponding management and intervention measures to help medical staff survive the psychological crisis and ensure the smooth progress of the prevention and control of the new crown pneumonia epidemic.

purpose: To observe the effect of ultrasound-guided intrafascial heat on ankle dorsiflexion of chronic gastrocnemius muscle injury contracture. Methods: 90 patients with chronic gastrocnemius muscle injury contracture were selected and these patients were randomized to three random groups (n=30): Static stretching therapy (group C), ultrasound-guided intrafascial hot needle release therapy (group R1), static stretching combined with ultrasound-guided intrafascial hot needle release therapy (group R2). Ankle dorsiflexion Angle (ADA) was measured before treatment, one week one month and three Months after treatment. Quantitative ultrasonography was used to evaluate the fascicle length (FL), pinnate Angle (PA) and muscle thickness (MT) of the medial gastrocnemic muscle, and the adverse reactions were recorded. Results: After treatment, ADA and FL increased, while PA and MT decreased in the 3 groups. In R2 group, ADA and FL increased and PA and MT decreased at one week, one month and three Months after treatment, which were better than those in R1 group and C group (P < 0.05); ADA, FL, PA and MT in group R1 at one week after treatment had no statistical significance compared with group C (P > 0.05), but the ADA, FL and PA and MT were higher than patients in group C (P < 0.05), and no serious complications occurred during the treatment. Conclusion: Ultrasound-guided intrafascial thermal needle release combined with static stretching can significantly improve the ankle dorsiflexion angle and restore muscle function in patients with chronic gastrocnemius muscle injury contracture, with definite efficacy and few adverse reactions, which is worthy of clinical promotion.

Objectives: As the Coronavirus disease 2019 (COVID-19) continues to spread and smokeless sports influences sports, large-scale sporting events fascinate international and national host-country athletes and millions of travelers, which has a profound impact on large-scale sports events. Based on the methods of literature, case analysis and induction, this paper analyzes the experience of holding smokeless large-scale sports events in the context of PHEIC through the epidemic background, the measures taken by countries and the results of holding large-scale sports events. The result shows that countries took measures to strengthen surveillance of infectious diseases and be fully prepared for any incident during PHEIC. Though it may need added resources and support, these endeavors were beneficial and formed part of the experience of major events. The successful experience of holding smokeless large-scale sports events in the context of PHEIC should not dissipate with the epidemic abating, but should actively upgrade theconcept of crisis management and explore the development path of smoke-free sports events. The path includes the following: International cooperation is the key to the success of large-scale sports events and potential intervention is an effective means to prevent the spread of epidemics. Risk communication provides effective guidance for the evolution of control and prevention of epidemics. The use of digital technology to monitor the outbreak of diseases in sports activities brings new opportunities for the public health prevention and treatment system, aiming to provide support for today's sports events, and then promote the construction of emergency prevention and control systems for large-scale sports events under the trend of globalization and normalization of the epidemic situation.

“Green design” has become a focal point and has caused widespread concerns around the world. In such a large environment, many designers’ sense of social responsibility is stimulated. When designing, they try to avoid the negative impact of the design on the environment, thereby reducing the environment. The key part of this article on the visual image design is the analysis and research of the visual elements of the cigarette label, combined with some examples of the visual image design of the modern cigarette label in some countries, firstly, it mainly analyzes the themes and cultural connotations involved in the modern cigarette label of the country. The analysis and research with pictures and texts are carried out from six aspects respectively. In the next part, this article discusses the graphic characteristics of cigarette labels from the three aspects of subject matter, expression method, and form of expression, and then discusses the color matching characteristics of cigarette labels from four aspects: three primary colors, composite colors and complementary colors, and black and white. Research and analysis of calligraphy fonts, artistic characters, Latin letters, and decorative fonts are given to explore their functions and roles in the visual image design of cigarette labels. Finally, through the analysis of typographic characteristics and Western progressive culture and design thoughts on cigarette label layout design influence, we discuss the characteristics and style of the cigarette label in the layout design.

Objectives: The health and well-ordered development of tobacco agriculture is very important. The incentive effects of plant-coupled subsidies and output-coupled subsidies on farming decisions with the consideration of uncertainty are investigated. The study shows that if the same unit subsidy is adopted, the incentive effect of the two policies will be determined by the expected output. When the expected output is higher, the incentive effect of the output-coupled subsidy is better than that of the plant-coupled subsidy. And when the expected output is lower, the incentive effect of the plant-coupled subsidy is better. If the implementation scheme limits the total amount of subsidies, it is better to determine subsidy policy by optimal output. The higher the optimal output is, the better the plant-coupled subsidy is. And when the optimal output is relatively low, the output-coupled subsidy shows a better incentive effect. Meanwhile, the study results also show that the incentive effects of the two coupled subsidy policies for increasing production and income are consistent, and the advantages of the policy with better incentive effects increase as the amount of subsidies increases.
