Objective To investigate the impact of minocycline(MC)on myocardial cell damage in rats with chronic heart failure(CHF)by regulating the hypoxia-inducible factor 1α(HIF-1α)/B-cell lymphoma-2/adenovirus E1B 19-kDa interacting protein(BNIP3).Methods All rats were randomly divided into Sham,CHF,positive drug(LP),low dose MC,high dose MC(HMC),and HMC+HIF-1α activator(DMOG)groups.Cardiac function was detected using echocardiography.HE staining,transmission electron microscopy,and TUNEL assay were used to evaluate myocardial pathology and apoptosis.Enzyme-linked immunosorbent assay was applied to quantify tumor necrosis factor α(TNF-α),interleukin-1β,superoxide dismutase(SOD),and malondialdehyde(MDA).Quantitative real-time PCR was used to detect the mRNA levels of Bcl-2 and Bcl-2-related X protein(Bax),while Western blotting was applied to detect the expres-sion of HIF-1α,BNIP3,Beclin-1,and microtubule-associated protein 1 light chain 3(LC3)proteins.Results Compared to rats in the sham group,rats from the CHF group exhibited increased left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),cell apoptosis rate,TNF-α,IL-1β,MDA,Bax,HIF-1α,BNIP3,Beclin-1,and LC3Ⅱ/Ⅰwith decreased left ventricular ejection fraction(LVEF),left ventricular shortening fraction(LVFS),SOD,and Bcl-2 levels(P<0.05).Compared with CHF group,rats from LP group,LMC group and HMC group exhibited decreased levels of LVEDD,LVESD,apoptosis rate,TNF-α,IL-1β,MDA,Bax,HIF-1α,BNIP3,Beclin-1,LC3Ⅱ/Ⅰ,and increased levels of LVEF,LVFS,SOD and Bcl-2(P<0.05).DMOG attenuated the protective effect of high-dose MC on myocardial cell damage in rats of the CHF group(P<0.05).Conclusion MC improves myocardial cell damage in rats of CHF group by inhibiting the HIF-1α/BNIP3 signaling pathway.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

With the continuous deepening of medical insurance payment reform, the implementation of the ambulatory patient groups(APG) based point system for payment has posed new challenges to the quality management of outpatient electronic medical record writing, as well as the supervision and operation management of outpatient costs in hospitals. A certain hospital began information technology construction in July 2021. By introducing diagnostic grouping functions into the outpatient electronic medical record system, the hospital strengthened the standardization of medical record writing. It also established an intelligent audit system for medical insurance costs to conduct full-process supervision of outpatient medical expenses and developed an intelligent operation analysis system for outpatient APG to provide a basis for hospital operation management decisions and performance distribution. These measures effectively improved the quality of outpatient medical record, reduced outpatient medical costs, and optimized their structure. The application of the intelligent medical insurance audit system also effectively prevented certain non-compliant issues in medical insurance payments, which can provide a reference for other medical institutions.

Objective To conduct basic research on the structure and function of the heart in cynomolgus monkeys older than 10 years to provide data for animal selection in elderly disease research.Methods A total of 144 cynomolgus monkeys＞10 years old were selected as research subjects,including 37 females and 66 males in the 10～15 years group,and 21 females and 20 males in the 16～20 years group.Basic data on cardiac structure and function in middle-aged and elderly cynomolgus monkeys were obtained through comparative analysis of general indicators(body mass index,blood pressure,and heart rate),blood biochemical indicators(blood glucose,blood lipids,and ion indicators),and cardiac structure and function indicators.Results General indicators for the 10～15 years and 16～20 years groups were compared.As age increased,the blood pressure and heart rate of female and male monkeys increased,and there was a significant difference in blood pressure changes between male monkeys.A comparison of two sets of blood biochemical indicators showed that,as age increased,blood glucose,triglycerides,total cholesterol,low-density lipoprotein cholesterol,blood calcium,blood sodium,and blood potassium increased,while lactate dehydrogenase decreased,in female and male monkeys.Among these,blood glucose,triglycerides(males),total cholesterol,high-density lipoprotein cholesterol(males),low-density lipoprotein cholesterol(males),blood calcium,blood sodium,blood potassium,and lactate dehydrogenase showed significant changes.A comparison of cardiac contractile function between the two groups showed that,as age increased,the anterior and posterior diameters of the left atrium significantly decreased in both female and male monkeys.Female monkeys showed a significant decrease in the interventricular septal end systolic diameter,left ventricular end diastole and systolic diameters,left ventricular end diastolic and systolic volumes,and left ventricular mass index,while no significant changes were seen in male monkeys.A comparison of diastolic function between the two groups showed that,as age increased,the late diastolic velocity of the mitral valve decreased significantly in male monkeys,while the early diastolic velocity of the left ventricular sidewall increased significantly in female monkeys.Correlation analysis was conducted between the metabolic indicators and the cardiac structure and function indicators of female and male monkeys.The correlations between metabolic indicators and cardiac structure and function indicators were weak in female monkeys,for which the maximum absolute Γ value did not exceed 0.39.However,the correlations between metabolic indicators and cardiac structure and function indicators were relatively strong in male monkeys,for which the maximum absolute Γ value reached 0.66.Conclusions Based on ultrasound analysis combined with metabolic indicators,the heart function of cynomolgus monkeys was studied,and basic data related to the structure and function of the heart in middle-aged and elderly cynomolgus monkeys were obtained.As age increased,blood glucose and lipid indicators increased in cynomolgus monkeys,while cardiac systolic and diastolic functions show a downward trend,similar to changes in middle-aged and older adult human populations.These data provide support for animal selection in research on age-related diseases related to heart function.
