Application of composite antibacterial nanoparticle non-woven fabric in sterilization of hospital infection.
The use of disinfection materials and instruments is an important part of surgical operation. Hospital environment and surgical equipment need comprehensive sterilization treatment. This process is the key to the success of the operation, and it is also one of the first ways to control the hospital to avoid infection during the operation. ⋯ In order to improve the antibacterial properties of medical non-woven fabrics, this paper combines two antibacterial methods of sterilization and antibacterial adhesion, and uses the principle of nanotechnology to design that the non-woven fabrics have good blood compatibility in the sterilization process. Then, a new composite antibacterial nanoparticle antibacterial solution is prepared from the synthesized nano‑silver solution, and the antibacterial solution is attached to the non-woven fabric, so that the nano‑silver particles with antibacterial effect are fixed on the surface of the fabric, and its antibacterial effect is measured through the antibacterial test, and excellent hospital infection sterilization technology is prepared and applied to the non-woven fabric products. The fusion experiment of platelets and red blood cells shows that the prepared surface technology combined with antibacterial adhesion and sterilization can effectively fuse with platelets and red blood cells, and can also effectively prevent the adhesion of platelets and red blood cells, and shows good blood compatibility, which is applicable to the sterilization process of hospital infection.

The preventive effect of PNF stretching exercise on sports injuries in physical education based on IoT data monitoring.
In physical education, in order to prevent sports injuries of students, it is necessary to study and build a set of physical education Internet of Things data monitoring training system to prevent sports injuries of students. This system is mainly composed of sensors, smart phones and cloud servers. ⋯ By analyzing students' sports data and health data, the system generates personalized training programs, including training intensity, training time, training frequency and other parameters, so as to meet the needs and actual conditions of different students and avoid sports injuries caused by overtraining. This system can better analyze and process the collected data, provide teachers with more comprehensive and in-depth assessment and monitoring of students' sports status, and provide students with more personalized and scientific training programs, so as to effectively prevent the occurrence of students' sports injuries.

Socioeconomic inequities and barriers to physical activity in Argentina.
Physical activity (PA) is recognized as a protective factor for health. Despite the importance that has been given to health differences in recent decades, strong inequities still persist. This article examines the inequities in the levels and barriers to PA in Argentina. ⋯ The main barrier to PA was lack of time (37.3%), followed by health reasons (24.3%) and lack of will (15.4%). Females, individuals who were married or in a couple relationship, those with incomplete secondary education, those who belonged to the three low-income quintiles, and people over 65 years old were 34% (OR 0.66 95% CI 0.59-0.65), 17% (OR 0.83 95% CI 0.79-0.88), 41% (OR 0.59 95% CI 0.56-0.62), 36% (OR 0.74 95% CI 0.70-0.78), and 51% (OR 0.49 95% CI 0.45-0.53) less likely to comply with WHO guidelines, respectively. To plan public policies to promote PA, it is necessary to consider inequities related to physical inactivity, while understanding the PA patterns according to social determinants.

Effect of DHCR7 for the co-occurrence of hypercholesterolemia and vitamin D deficiency in type 2 diabetes: Perspective of health prevention.
Type 2 diabetes mellitus (T2DM) is a complex disease caused by multiple factors, which are often accompanied by the disorder of glucose and lipid metabolism and the lack of vitamin D. Over the years, researchers have conducted numerous studies into the pathogenesis and prevention strategies of diabetes. In this study, diabetic SD rats were randomly divided into type 2 diabetes group, vitamin D intervention group, 7-dehydrocholesterole reductase (DHCR7) inhibitor intervention group, simvastatin intervention group, and naive control group. ⋯ Overall, DHCR7 is an indicator for type 2 diabetic glycolipid metabolism disorder and vitamin D deficiency. Targeting DHCR7 will help with T2DM therapy. The management model of comprehensive health intervention can timely discover the disease problems of diabetes patients and high-risk groups and reduce the incidence of diabetes.

The physical activity implications of retirement across occupational activity groups.
Retirement is an important later life transition which may represent a critical period for physical activity in older age. Past findings on the association between retirement and physical activity are inconclusive and there is some evidence that the physical activity implications of retirement may differ by occupational activity level. This study used data from waves 4-9 (June 2008-July 2019) of the English Longitudinal Study on Aging to evaluate whether there is an association between retirement and physical activity, and whether this varies across occupational activity groups. ⋯ This study quantified the importance of retirement for later life physical activity. With demographic aging, the population health importance of later life physical activity will likely become more important. These findings should inform the design of public health interventions to increase physical activity around the retirement transition.
