By combing out the historical development logic of sports and health integration and the current development achievement, the underlying logic of sports and health integration is described systematically in multiple dimensions, and the prominent dilemmas in development are analyzed as follows: lack of residents' health literacy, excessive dependence on medical treatment, low bridging of talent team construction, lack of the guidance of funds centralization, insufficient financial support, imperfect management system and mechanism, and unspecific departmental collaboration.The strategies for solving the problems are as follows: strengthening the integration of sports science and clinical medicine, consolidating the technical integration of sports prescription and clinical standardization process, further improving the business integration of exercise intervention and clinical treatment, and enhancing the industrial integration of sports products and medical treatment.

Fitness for all has undergone development more than two decades in China, from " outline" to " national strategy" . As an important support for realizing a healthy China and an important guarantee for the great rejuvenation of the Chinese nation, national fitness should keep pace with the development of the times, grasp the characteristics of national fitness in the new period, and constantly explore new horizons and develop new achievements.Scientific fitness literacy is a new system put forward by combining the latest achievements of research and practice in the field of national fitness at home and abroad with China's national conditions, including four dimensions: scientific fitness knowledge, scientific fitness attitudes, scientific fitness behaviors and habits, and scientific fitness abilities and skills.The purpose of this paper is to clarify the philosophical basis of scientific fitness literacy, the disciplines involved, the meanings, the specific components and the ultimate goal, so as to provide an analytical framework and a theoretical basis for the next step of the research, and also to provide a reference for the formulation of national fitness policies, the evaluation and supervision of the implementation process and results, and the comparison of the practice among countries.

Objective:To investigate the current status of scientific fitness literacy (SFL) and its influencing factors among Chinese adults aged 20-59 years.Methods:Totally 63 338 adults aged 20-59 years in the status of national fitness activities in 2020 from 1 January to 31 March 2020 were selected as the subjects, and they were divided into four age groups, namely, the 20-29 age group, the 30-39 age group, the 40-49 age group and the 50-59 age group. Data were analyzed by SPSS 29.0.Comparative analyses for age, gender, urban-rural difference were carried out by applying non-parametric tests, and multiple regression models were applied to find the influencing factors of SFL.Results:The SFL score of Chinese adults aged 20-59 years was 53.40 (41.67, 63.73), and the scores of cognition, attitude, ability and skills, behavior and habits sub-dimensions were 86.11 (72.22, 100.00), 62.96 (50.62, 75.31), 27.78 (11.11, 44.44) and 33.33 (11.11, 55.56), respectively. The SFL and the four sub-dimensions were demonstrated to have higher scores for males than females, and higher scores for adults in urban area than those in rural area(all P<0.01). The multiple regression results showed that regular exercise at a fitness facility (20-29 age group: β=0.321, t=5.940, P<0.01; 30-39 age group: β=0.187, t=2.937, P<0.01; 40-49 age group: β=0.230, t=3.988, P<0.01; 50-59 age group: β=0.415, t=5.671, P<0.01) was the Chinese adults' common influence factor on SFL.Motivation, evaluation by those around them, experience from exercising, and convenience and atmosphere of exercising were the main influence factors in the 20-29 and 30-39 age groups(all P<0.05).Comfort level of fitness venue, convenience, safety, and support of fitness place were the main influence factors in adults aged 40-59 years(all P<0.05). Conclusions:Chinese adults aged 20-59 years old have high SFL awareness scores, but low overall SFL scores. Surrounding people's evaluation, experience in exercise, comfort level of fitness place, convenience, safety and fitness policy support are the influential factors of scientific fitness literacy.

BACKGROUND:Stem cells can promote nerve regeneration,repair damaged nerves,inhibit inflammation and apoptosis of nerve cells,and provide a new way for the treatment of Alzheimer's disease. OBJECTIVE:To make a bibliometrical analysis of the articles on stem cell therapy for Alzheimer's disease published internationally from 2004 to 2023,in order to reveal the research hotspot and trend of stem cell therapy for Alzheimer's disease. METHODS:From the Web of Science Core Collection database,by using Excel,VOSviewer,and Citespace software,the annual number of publications,countries,institutions,journals/co-cited journals,authors,and keywords of articles related to stem cells and Alzheimer's disease published from January 1,2004 to October 31,2023 were visually analyzed. RESULTS AND CONCLUSION:A total of 3 521 core papers were included,and the number of published papers increased year by year.The United States is the country with the most papers.Harvard Medical School is the most prolific institution.Maiese kenneth is the author with the most papers.International Journal of Molecular Sciences has the most papers in this field.The journal PLoS One published the most citations.At present,the field of stem cell therapy for Alzheimer's disease focuses on pathophysiological mechanism and animal experimental research,and"neurogenesis","oxidative stress","extracellular vesicles",and"mesenchymal stem cells"are the research trends in this field.Stem cell therapy for Alzheimer's disease has broad prospects.In the future,exchanges and cooperation between institutions and authors should be strengthened to further explore the main mechanism of stem cell therapy for Alzheimer's disease,solve possible clinical problems such as immune rejection,effectiveness,and safety,and further tap the potential of stem cells in the treatment of Alzheimer's disease.
