Since the new era, overseas research on the CPC has continued to heat up. This paper analyzed overseas research on the CPC based on the literature with the theme of "The Communist Party of China" between 2013 and 2022 in the core collection of Web of Science databases with CiteSpace software. The study found that the overseas research on the CPC mainly focused on three aspects: governance of China, promotion of officials, and primary-level governance in the regime; it showed the characteristics of a continuous expansion of the research team, clear problem awareness, diversification of research theories and methods, and a gradual shift from macro research to mesoscopic and microscopic research. However, there are also deficiencies, such as exaggeration and a lack of understanding of China's history and culture, etc. Therefore, making a holistic and comprehensive understanding and grasp of the study of the CPC overseas, telling the Chinese story and transmitting Chinese voice can better cultivate new opportunities in the crisis and open a new situation in the changing situation. This study can provide useful references for the theoretical research of the 20th National Congress and overseas propaganda work. [ABSTRACT FROM AUTHOR]

BACKGROUND: Patellofemoral pain syndrome is a common disease in the field of sports injuries. Research in and outside China is increasing year by year, but there is no visual analysis for patellofemoral pain syndrome. OBJECTIVE: To objectively analyze the literature research on patellofemoral pain syndrome in and outside China in the past 13 years, to summarize the recent research directions in this field and to sort out the knowledge structure in and outside China. METHODS: Relevant articles on patellofemoral pain syndrome were collected from Web of Science and CNKI. Citespace software was used for visual analysis to show the research hotspots and development trends of this field. RESULTS AND CONCLUSION: (1) A total of 1 679 articles were finally included in the Web of Science database. The authors with the most articles are De Oliveira Silva D from La Trobe University in Melbourne, Australia and Crossley KM from the University of Melbourne, Australia. Hot keywords are hip, biomechanics, prevention (prognosis), prevalence disease rate, consensus statement, gender differences, electromyographic activity, risk factor, and osteoarthritis. (2) A total of 214 articles were included and analyzed in the CNKI database. The author with the most articles is Miao Ping from the Rehabilitation Department of the Second Affiliated Hospital of Guangzhou Medical University. Hot keywords are arthroscopy, biomechanics, strength training, lateral femoral muscle, surface electromyography, patellofemoral arthritis, and joint replacement. (3) International research hotspots show the biomechanical characteristics of increased knee external rotation, increased hip adduction, and decreased hip internal rotation during patient exercise. Strengthening the hip abductors and external rotators can effectively improve the pain and function of patients. At present, the most appropriate method to treat the disease in the world is a customized multi-modal intervention program, including strengthening of the gluteal muscles and quadriceps, emphasizing education and activity adjustment. (4) The results of major Chinese studies in this field confirm that the use of arthroscopic surgery can improve the pain of patients with patellofemoral pain syndrome, and patellofemoral joint replacement has a certain effect on early severe patellofemoral arthritis in such patients. Rehabilitation training methods are mainly based on hip joint strength training, supplemented by core muscles, lower limb eccentric strength and neuromuscular control training. Compared with foreign countries, the unique research hotspots in China are acupuncture and Chinese medicine. [ABSTRACT FROM AUTHOR]
