Objective To analyze the research hotspots and development trends regarding the effect of proprioceptive training in the rehabilitation of anterior cruciate ligament(ACL)injury.Methods Relevant literatures on the effect of proprioceptive training on ACL injury rehabilitation were retrieved in the Web of Science Core Collection database from 2015 to 2024,and were analyzed with CiteSpace 6.2 R4.Results A total of 108 articles were included,with a fluctuating trend in publication volume,and the number of publica-tions peaked in 2021.The United States and China published the most articles.High-frequency keywords includ-ed posture balance,neuromuscular control,joint position sense,muscle strength and gait analysis.The most cen-tral keyword was posture stability.The research focused on improving the postoperative rehabilitation outcomes and efficiency of ACL injury,with particular emphasis on returning to play,posture stability,strength training and knee joint function.Conclusion Proprioceptive training can enhance proprioception and motor control of patients with ACL injury and im-prove rehabilitation outcomes by strengthening rehabilitation techniques and optimizing treatment approaches.Future research should continue to focus on the diversification of proprioceptive training,the individulization of rehabilitation plans and the application of new technologies.

ObjectiveThis research focused on examining the distinctive characteristics of nutrient intake and dietary patterns among long-lived elderly individuals. Additionally， the study was aimed to explore the specific dietary components that may impact the skeletal muscle mass in this particular group. MethodsThis study was conducted in the Chongming area of Shanghai， China. A total of 206 long-lived elderly individuals aged 90 or above were recruited. The 3-day 24-hour dietary recall method was used to collect dietary information and general demographic data through face-to-face interviews with professional nutritionists. The skeletal muscle mass index（SMI） was measured by bioelectrical impedance analysis（BIA）， and low skeletal muscle mass was diagnosed based on the 2019 Asian Working Group for Sarcopenia criteria. T-test analysis， chi-square test， and logistic regression were used to analyze the relationship between dietary nutrient intake and skeletal muscle mass. ResultsIn terms of food intake categories， compared with the long-lived elderly people with normal muscle mass， the intake of cereals containing miscellaneous beans and vegetables in the long-lived elderly people with low muscle mass was significantly lower（P<0.05）. In terms of the nutrient intake， compared with the long-lived elderly people with normal muscle mass， the intake of total energy， carbohydrate， dietary fiber， vitamin D， folic acid， phosphorus， potassium， magnesium， iron， and manganese in the long-lived elderly people with low muscle mass was significantly lower（P<0.05）. After continuous adjustment for the covariates， multivariate logistic regression analysis found that the intake levels of folic acid and dietary fiber were important factors influencing skeletal muscle mass， Individuals with lower intake levels of folic acid and dietary fiber are at a higher risk of low muscle mass in long-lived elderly individuals ［OR_{folic acid T1}， _{dietary fiber T1} （95%CI）： 2.90 （1.11‒7.61）； 4.09 （1.53‒10.91）］. ConclusionThe consumption of cereals that include a variety of beans and vegetables was noticeably lower in the long-lived elderly individuals with lower muscle mass when compared to those with normal muscle mass. Furthermore， low levels of folic acid and dietary fiber intake are associated with an increased risk of low skeletal muscle mass.

The United States is the country with the most pilot practices in value-based healthcare payment reform, and value-based purchasing (VBP) is one of its pilot projects. The authors introduced the basic situation and implementation effects of the pilot projects of VBP payment reform in the United States from the hospital and physician levels respectively, and analyzed the causes for their unsatisfactory implementation effects. Then, the authors proposed its enlightenments for China from such aspects as the construction of value-based medical payment index system, implementation of value-based medical payment reform, and management costs, to provide reference for the construction of high-quality value-based medical service system in China.

The pilot project for alternative payment models was originated from the implementation of the 2010 Affordable Care Act in the United States, which aimed to establish a new payment mode to replace the traditional payment based on service fees, thereby achieving the goals of ensuring healthcare quality, reducing healthcare costs, and improving healthcare equity. The pilot projects of alternative payment models included two types: accountable care organizations and bundled payments for care improvement. The authors introduced their profile and implementation effects, analyzed the causes of the current implementation effects, and then proposed enlightenments for the value-based medical payment reform in China, with the aim of providing reference for the construction of a high-quality value based medical service system in China.
