Caloric restriction (CR) is a well-established dietary intervention known to extend healthy lifespan and exert positive effects on aging-related diseases, including cardiovascular conditions. Sirtuins, a family of nicotinamide adenine dinucleotide (NAD +)-dependent histone deacetylases, have emerged as key regulators of cellular metabolism, stress responses, and the aging process, serving as energy status sensors in response to CR. However, the mechanism through which CR regulates Sirtuin function to ameliorate cardiovascular disease remains unclear. This review not only provided an overview of recent research investigating the interplay between Sirtuins and CR, specifically focusing on their potential implications for cardiovascular health, but also provided a comprehensive summary of the benefits of CR for the cardiovascular system mediated directly via Sirtuins. CR has also been shown to have considerable impact on specific metabolic organs, leading to the production of small molecules that enter systemic circulation and subsequently regulate Sirtuin activity within the cardiovascular system. The direct and indirect effects of CR offer a potential mechanism for Sirtuin modulation and subsequent cardiovascular protection. Understanding the interplay between CR and Sirtuins will provide new insights for the development of interventions to prevent and treat cardiovascular diseases.

Objective:To assess the impact of the construction of smoke-free government on the smoking and cessation behaviors of staff members.Methods:This was a retrospective cohort study. The study used stratified random cluster sampling method to select 144 government institutions from 31 Provinces (Autonomous Regions and Municipalities) and the Xinjiang Production and Construction Corps. The survey was carried out between October and November, 2023 by filling out questionnaires online among the insiders of the institutions and all the smoking staff members. The main indicators included the number of smokers before and after the construction of smoke-free governments and the measures for the construction of smoke-free governments. 144 questionnaires from insiders were recovered, all of which were included in the analysis; 1 776 questionnaires from smokers were recovered, including 1 716 valid questionnaires. The SAS 9.4 was used to perform χ 2 test and log-binomial regression analysis. Results:The percentage of smoking staff members decreased from 8.81% before the construction to 6.70% after the construction, and the difference was statistically significant ( χ 2=63.23, P<0.001). Comprehensive smoking ban in indoor public places ( OR=2.301, 95% CI: 1.433-3.694), punishment mechanism for smoking staff members ( OR=1.219, 95% CI: 1.124-1.322), smoking cessation competitions ( OR=1.865, 95% CI: 1.234-2.818) and reimbursement for or provision of smoking cessation medications ( OR=2.210, 95% CI: 1.002-4.874) were facilitators to motivate the smoking staff members to quit (all P<0.01). Numbers of smoking leaders ( OR=0.858, 95% CI: 0.807-0.913) and smoking years of smoking staff members ( OR=0.932, 95% CI: 0.918-0.946) negatively influenced the smoking staff members to quit (both P<0.001). Conclusions:The construction of smoke-free governments can effectively promote the smoking cessation behaviors of smoking staff members. In addition, comprehensive smoke-free policies, punishment mechanism for smoking staff members and activities such as smoking cessation competitions, and reimbursement for or provision of smoking cessation medications are important.

Objective To investigate the effect of resistance training on the rehabilitation of patients after hip replacement with the framework of the theory of planned behavior(TPB).Methods A total of 85 patients of hip fracture patients in Gansu Provincial Hospital of Traditional Chinese Medicine from July 2022 to April 2023 were selected as research objects.The patients were separated into intervention group(n=43)and control group(n=42)by random sampling.Both groups were treated with routine nursing,and the intervention group was given resistance training based on TPB.The intervention time was 3 months.The Harris hip score(HHS),36-item short form(SF-36)score and Barthel index(BI)scores of the two groups were compared before intervention,1 month and 3 months after intervention,as well as the functional exercise compliance score of the patients 3 months after intervention.Results After 1 month and 3 months of intervention,the HHS,SF-36 score and BI score of intervention group were better than those of control group,and after 3 months of intervention,the executive ability of functional exercise in intervention group was significantly higher than that of control group,and the mean difference was significant(P＜0.05).Conclusion Resistance training led by TPB can effectively improve the functional exercise compliance of patients after total hip arthroplasty,improve the muscle strength,balance ability and joint stability of patients,and then improve the daily activity ability and quality of life.

Objective To retrospectively analyze the efficacy and safety of abatacept(ABA)in anti citrullinated peptide antibody(ACPA)positive rheumatoid arthritis(RA).Methods Clinical data from ACPA positive RA patients who visited the Department of Rheumatology and Immunology at the Second Hospital of Hebei Medical University from May 2020 to January 2023 and were treated with ABA were retrospectively collected and analyzed,to evaluate the efficacy and safety of ABA at 12 weeks and 24 weeks of treatment.Efficacy evaluation measures included RA disease activity score-28(DAS-28),clinical disease activity index(CDAI),and remission criteria of RA of American College of Rheumatology(ACR).Results A total of 35 ACPA-positive RA patients were included in the final analysis.The DAS-28,CDAI,ACR20,ACR50,and ACR70 remission rates at 12 weeks after treatment were 34.29%,31.43%,60.00%,28.57%,and 14.29%,respectively;the DAS-28,CDAI,ACR20,ACR50,and ACR70 remission rates at 24 weeks after treatment were 74.29%,82.86%,85.71%,54.29%,and 31.43%,respectively;in addition,the remission rate at 24 weeks was significantly higher than that at 12 weeks(P﹤0.05).Among the 35 patients included in the analysis,4 patients experienced respiratory tract infections,3 patients experienced transient creatinine elevation,and 4 patients experienced elevated blood uric acid.Conclusion In the real world,ABA's clinical remission rate is consistent with expectations,and clinical combination drug regimens are flexible and diverse,with high drug safety.
