Objective To systematically analyze the characteristics of the disease burden of hypertensive heart disease (HHD) in the elderly (≥60 years) globally and in China from 1990 to 2021, and to predict its future trends from 2022 to 2040, with the aim of providing data support for optimizing comprehensive prevention and control strategies for HHD. Methods Based on the Global Burden of Disease (GBD) 2021 database, the number of prevalent cases and disability-adjusted life years (DALYs) of HHD in the elderly were extracted for the world, China, and five regions categorized by sociodemographic index (SDI). Joinpoint regression was used to analyze the temporal trends of age-standardized prevalence rate and age-standardized DALYs rate of HHD in the elderly. A three-factor decomposition method was applied to evaluate the relative contributions of aging, population growth, and epidemiological changes to the variations in the elderly HHD burden. Additionally, a Bayesian age-period-cohort model was used to predict the elderly HHD burden from 2022 to 2040. Results In 2021, the number of prevalent elderly HHD cases reached 10 283 000 globally and 3 412 400 in China, representing increases of 179.20% and 159.20% respectively, compared with 1990. The DALYs of elderly HHD were 18 812 700 person-years globally and 4 731 400 person-years in China, rising by 76.08% and 29.45% respectively from 1990. Meanwhile, the growth rates of the number of prevalent cases and DALYs of elderly HHD varied across different SDI regions. From 1990 to 2021, the age-standardized prevalence rate of elderly HHD in China, as well as the age-standardized DALYs rate of elderly HHD both globally and in China, showed significant downward trends (all average annual percentage changes<0, all P<0.001). In 2021, the 70-74 years age group accounted for the highest proportion of prevalent cases and DALYs of elderly HHD, both globally and in China. Decomposition analysis revealed that population growth was the dominant factor driving the increase in the elderly HHD burden across all regions. The prediction model results indicated that the number of prevalent cases and DALYs of elderly HHD would continue to rise globally and in China from 2022 to 2040, with the growth rate of the elderly HHD burden in China between 2021 and 2040 expected to exceed the global average. Conclusion Over the past 32 years, although the age-standardized disease rates of elderly HHD have mainly shown a downward trend globally and in China, the absolute number of the disease burden has increased substantially. The projection model indicates a continued upward trajectory, with the growth rate in China higher than the global average. Therefore, there is an urgent need to implement precise prevention and control strategies to effectively mitigate the disease burden of elderly HHD.

Radiation-induced heart disease(RIHD)is a severe complication in patients with thoracic cancer undergoing radiotherapy,with important impacts on long-term survival among cancer survivors.There is an urgent need to investigate the pathogenesis of RIHD and to develop effective therapeutic agents,and the establishment of high-quality RIHD animal models is pivotal to addressing these issues.This review summarizes the critical factors to consider in establishing RIHD animal models,including species selection,radiation type,dosage,fractionation,and target fields,and modeling timeline,along with the evaluation method and success criteria.We also consider the potential pathogenic mechanisms underlying RIHD,including DNA damage,oxidative stress,inflammatory responses,mitochondrial dysfunction,renin-angiotensin-aldosterone system activation,and myocardial fibrosis,as well as their interrelationships.These insights provide a comprehensive reference framework for constructing RIHD animal models and advancing mechanistic investigations into this condition.

Myocardial ischemia-reperfusion(I/R)injury refers to the irreversible cardiac damage and cardio-myocyte apoptosis that occur upon the restoration of blood flow following ischemia in ischemic heart disease(IHD).Given its high incidence,elevated mortality rate,and poor clinical outcomes,the prevention and treatment of I/R injury are of considerable clinical significance.Mitochondrial dynamics dysfunction,characterized by abnormalities in mitochondrial morphology,fission,and fusion,has emerged as a critical pathological feature.Evidence indicates that correcting these dysfunctions can enhance myocardial energy metabolism,mitigate oxidative stress,calcium overload,and inflammatory responses,and inhibit the pathological opening of the mitochondrial permeability transition pore and vascular remodeling.These effects position mitochondrial dynamics as a promising therapeutic target for IHD and I/R injury.This paper ex-plores the pathophysiological mechanisms by which mitochondrial dynamics dysfunction in cardiomyocytes,vascular endo-thelial cells,and vascular smooth muscle cells contributes to the development and progression of I/R injury,aiming to of-fer novel insights into its prevention and treatment.

ObjectiveMaxing Shigan Tang， as a traditional prescription for treating pneumonia， has a remarkable clinical effect. This study aims to systematically investigate the molecular mechanisms of Maxing Shigan Tang in treating pneumonia by integrating its structural and transcriptomic data at the target level. MethodsNP-TCMtarget， a developed systematic network pharmacological model focusing on drug targets， was used to mine the effect targets of Maxing Shigan Tang for treating pneumonia based on the transcriptome data. The structural targets of chemical components in Maxing Shigan Tang were predicted based on the structural information. The intersection of effect targets and structural targets was taken as the direct targets of Maxing Shigan Tang for treating pneumonia， and the remaining effect targets except direct targets were taken as indirect targets. Finally， functional enrichment analysis was performed on these targets to explore the molecular mechanism of Maxing Shigan Tang in treating pneumonia. ResultsA total of 1 604 effect targets and 816 structural targets of Maxing Shigan Tang for treating pneumonia were identified. Maxing Shigan Tang exerted its therapeutic effects through 164 direct targets and 1 440 indirect targets. The functional analysis of 1 604 effect targets predicted 19 significantly enriched pathways. Comprehensive analysis of these pathways showed that these targets were mainly linked to immune and inflammatory responses， such as cytokine-cytokine receptor interaction， necrosis factor （NF）-κB signaling pathway， and helper T cell 17 differentiation. ConclusionFocusing on the hierarchical feature of drug targets and the structural and transcriptomic data， this study systematically reveals the path of herbal component-direct target-indirect target-biological effects of Maxing Shigan Tang in treating pneumonia.
