Action recognition for sports combined training based on wearable sensor technology and SVM prediction.
In the field of sports, coaches have mainly relied on observing the performance of athletes on the spot to formulate suitable training plans for athletes, which has extremely high requirements for the professionalism of coaches. Based on the above requirements, this paper designs a sports action recognition system for sports enthusiasts based on the SVM algorithm optimization model, and for the purpose of verifying the applicability of the system to different sports fields, experiments are carried out on basketball actions and race walking actions. The system uses wearable sensors to capture the motion data of the user, and then analyzes and identifies the user's actions through the SVM algorithm optimization model. ⋯ Combining the forward kinematics of the robot and the homogeneous coordinate transformation, the human body joint rotation motion model and the human bone position and posture model are established. In the end, the user can standardize the sports combination training under the system algorithm. In this paper, through the research of wearable sensor technology and sports combined training action recognition, and apply it to practical life, it aims to promote its development and application.

Analysis of metabolic syndrome and cognitive functional analysis in schizophrenic patients based on psychological intervention.
In this paper, we explore the characteristics of cognitive dysfunction in patients with schizophrenia complicated with metabolic syndrome (MS), and to explore the effects of psychological intervention on MS and cognitive function changes in patients with schizophrenia, and to provide theoretical basis for early intervention of MS. 159 patients with schizophrenia were retrospectively analyzed and divided into 2 groups according to whether they were accompanied by MS. (41 cases), the second group was not MS. (118 cases). Results shows PANSS total score as (53.72 ± 5.03), positive symptom score (12.39 ± 2.68), negative symptom score (14.94 ± 3.27), general pathological score (26.27 ± 3.63). ⋯ Increasing psychological intervention can effectively improve the therapeutic effect and cognitive function of schizophrenia patients. Early identification and intervention of MS in the clinical treatment of schizophrenia is particularly important.

A novel protective role of lipoxin in inhibiting diabetic vascular calcification via YAP signalling: Health prevention and regulation.
Vascular calcification is highly prevalent in diabetes patients, with detrimental consequences and no effective prevention and treatment strategies are currently available. Though the protective effect of lipoxin (LX) against vascular diseases has been demonstrated, its effect on diabetic vascular calcification remains unknown. AGEs dose-dependently induced calcification and the expression of osteogenesis-related markers, coupled with the activation of yes-associated protein (YAP). ⋯ Further, an in vivo diabetic mouse model was established using a combination of a high-fat diet and multiple formulations of low-dose streptozotocin. Consistent with the in vitro results, diabetes promoted YAP expression and its subcellular localization in the nucleus in the arterial tunica media. The results demonstrate that LX attenuates the trans-differentiation and calcification of VSMCs in diabetes mellitus via YAP signalling, suggesting LX to be a potent therapeutic for preventing diabetic vascular calcification.

Accumulating evidence suggests that the built environment may be associated with cardiovascular disease via its influence on health behaviours. The aim of this study was to estimate the associations between traditional and novel neighbourhood built environment metrics and clinically assessed cardio-metabolic risk factors among a sample of adults in Canada. A total of 7171 participants from Albertas Tomorrow Project living in Alberta, Canada, were included. ⋯ Space syntax walkability was also associated with lower odds of overweight/obese among women and men (OR = 0.93, 95% CI 0.87, 0.99 and OR = 0.88, 95% CI 0.79, 0.97, respectively). No significant associations were observed between traditional walkability and cardio-metabolic outcomes. This study showed that the novel built environment metric based on the space syntax theory was associated with some cardio-metabolic risk factors.

Yield and cost of government-organized colorectal cancer screening in young high-risk population in Northeast China.
Guidelines for colorectal cancer (CRC) screening recommend screening at age 40 for high-risk population in China. However, the yield and cost of CRC screening in younger population are lacking. This analysis aimed to evaluate the yield and cost of CRC screening in high-risk 40- to 54-year-olds. ⋯ Among the male screening population, NNS and cost to detect one advanced lesion in participants aged 45-49 years were similar to that aged 50-54 years, saving approximately half endoscopic resources and financial expenses compared with screening that aged 40-44 years. From the perspective of screening results and costs, it might be beneficial to delay the starting age of screening by gender. This study may provide reference for optimizing CRC screening strategies.
