Explainable quality assessment of effective aligned skeletal representations for martial arts movements by multi-machine learning decisions.

How to utilize modern technological means to provide both accurate scoring and objective feedback for martial arts movements has become an issue that needs to be addressed in the field of physical education. This study proposes an intelligent scoring method based on machine learning. Firstly, the key features are extracted by the feature alignment technique, which eliminates the influence of athletes' movement speed, rhythm and duration on the scoring, thus reflecting the athletes' skill level more realistically.

Association between physical activity levels and stroke risk among Chinese adults aged 45 and over based on CHARLS.

Stroke is one of the leading causes of death in developing countries, and China bears the largest global burden of stroke. This study aims to investigate the relationship between different dimensions of physical activity levels and stroke risk using a nationally representative database. We performed a cross-sectional analysis using data from the China Health and Retirement Longitudinal Study (CHARLS) 2020.

Association of physical activity with socio-economic status and chronic disease in older adults in China: cross-sectional findings from the survey of CLASS 2020 after the outbreak of COVID-19.

Background: In 2021, China had a population of 264·01 million individuals over the age of 60, indicating a high prevalence of chronic diseases. Among older adults, physical inactivity (PI) is a significant risk factor for chronic diseases. However, few studies have been conducted on the correlation of physical activity (PA) with the economic status, geography and chronic disease risks in Chinese elderly.

Revealing the Inner-relevance of College Students' Physical Fitness by Association Analysis and Neural Network.

The physical activity and health status of the students in China are not optimistic, there is a general lack of exercise volume and exercise intensity. Normal college students shoulder the future of China's education. Promoting their physical health is the basic requirement for cultivating teachers in the new era; Methods:Testing and recording 1123 male, 3266 female college students' physical fitness indicators in a normal college, the relationship between these indicators was mined by correlation analysis and Apriori, and the intelligent prediction models was constructed according to the mined knowledge; Results: There was no correlation between male 1000m running and vital capacity (P > 0.

Triiodothyronine potentiates angiogenesis-related factor expression through PI3K/AKT signaling pathway in human osteoarthritic osteoblasts.

Objectives: Previous study has indicated that triiodothyronine (T3) facilitated cartilage degeneration in osteoarthritis (OA). This study aimed to investigate the effects of T3 on angiogenesis-related factor expression in human osteoblasts of OA subchondral bone.

Materials And Methods: The subchondral bone specimens were obtained from OA patients and healthy participants.

Abnormal thyroid hormone receptor signaling in osteoarthritic osteoblasts regulates microangiogenesis in subchondral bone.

Aims: Previous study indicated that the increase of local bio-availability of 3'3'5-triiodothyronine (T3) influenced osteoarthritis (OA) initiation. We aimed to investigate the role of thyroid hormone receptors (THRs) signaling in OA osteoblasts.

Materials And Methods: THRs expression in OA was detected by immunohistochemistry, immunofluorescence, RT-qPCR and western blotting.

Ricolinostat (ACY-1215) inhibits VEGF expression via PI3K/AKT pathway and promotes apoptosis in osteoarthritic osteoblasts.

Osteoarthritis (OA) is involved in these pathophysiological changes of articular cartilage, subchondral bone and synovium. As a selective HDAC6 inhibitor, Ricolinostat (ACY-1215) has demonstrated chondroprotective effects in OA. However, its efficacy remains unclear in subchondral bone.
