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.

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.

Acute urinary retention(AUR)occurs frequently among astronauts on orbit.The current treatment is complex and easy to damage the urethra,which seriously affects the life and work of astronauts.In contrast,acupuncture,a traditional Chinese remedy,has shown promising results in managing urinary retention.However,the specific acupoints that could potentially prevent AUR remain uncertain due to the unique physiological conditions experienced by individuals in space compared to those on Earth.To address this gap,our research delved into the mechanisms of AUR and acupuncture within both traditional Chinese medicine and modern medical practices.We conducted a thorough literature review from Pubmed,Web of Science,CNKI,Wanfang database,VIP database and Chinese Medical Code database.A hierarchical evidence-scoring approach was utilized to analyze the included literatures,thus devised acupuncture protocols for the treatment of AUR.The outcomes of our study aim to establish a foundation for the application of acupuncture in managing AUR.

Under the influence of long-term space flights and the confined space environment,it is very easy to induce space depression syndrome,mainly manifested as decreased emotional stability,sleep disorders,mental fatigue,etc.,which seriously affect the living conditions and working abilities of astronauts.The current treatment methods mainly focus on psychological support and drug intervention.Acupuncture has a good effect in treating depression.Therefore,starting from the TCM pathogenesis and modern medical pathogenesis of aerospace depression syndrome,we conducted literature retrieval from databases such as the Chinese Medical Classic,China National Knowledge Infrastructure(CNKI),Wanfang,VIP,PubMed,and Web of science.For the included literature,we adopted the stratified evidence scoring method and combined the TCM mechanism and modern medical mechanism of the effect of acupuncture.A prescription for acupuncture points was constructed to provide a basis for selecting acupuncture points for the prevention of aerospace depression syndrome through acupuncture.

Acute myocardial infarction(AMI)is a common cardiovascular emergency in clinic.Early reperfusion is a typical and effective method for the treatment of AMI.However,the recovery of blood supply after reperfusion therapy will accelerate the damage of ischemic myocardium and cause myocardial ischemia-reperfusion injury(MI/RI).In recent years,studies have found that TCM has the unique advantages of multi-component,multi-channel and multi-target in the intervention of MI/RI.Janus tyrosine kinase/signal transducer and activator of transcription(JAK/STAT)signaling pathway is closely related to MI/RI,which can reduce MI/RI process by regulating inflammation,oxidative stress,cell proliferation,differentiation and apoptosis.This article reviewed the mechanism of JAK/STAT signaling pathway in MI/RI and the research of TCM targeting this pathway,in order to provide references for the prevention and treatment of MI/RI and further drug development.

Myocardial injury is a pathological change of myocardium caused by many factors,which can lead to the decline of cardiac function and the occurrence of cardiovascular events.Astragaloside Ⅳ is one of the main pharmacological components in Astragali Radix,which plays an anti-myocardial injury role by regulating various signaling pathways.This article reviewed the anti-myocardial injury mechanism of astragaloside Ⅳ from five aspects:inhibition of oxidative stress,inhibition of apoptosis,anti-myocardial fibrosis,improvement of myocardial energy metabolism and inhibition of myocardium inflammation,in order to provide reference for the mechanism research and clinical application of astragaloside Ⅳ in the prevention and treatment of myocardial injury.

Objective:To evaluate the efficacy and safety of 532-nm picosecond laser in the treatment of early-stage facial seborrheic keratosis.Methods:A total of 95 patients with early-stage facial seborrheic keratosis were prospectively enrolled from the Department of Dermatology, General Hospital of Ningxia Medical University between December 2020 and September 2022. All the patients received a session of 532-nm picosecond laser treatment, and were followed up for 6 months. A 4-point scale was used to evaluate the overall improvement of skin lesions for assessing the clinical efficacy. A VISIA skin detector was used to quantitatively determine the characteristic counts, absolute scores, and percentiles of brown spots before and after treatment, and the paired sample t-test was used to compare the quantitative indicators of brown spots before and after treatment. The patients′ pain grades were evaluated, and adverse reactions were recorded. Results:All the 95 patients with early-stage facial seborrheic keratosis received a session of 532-nm picosecond laser treatment, and completed a 6-month follow-up. All the patients achieved over 25% regression of skin lesions in the treatment area, of whom 10 received mild improvement, 17 received favorable improvement, and 68 received marked improvement, with the response rate being 89.47% (85/95). The examination with the VISIA skin detector showed that the characteristic counts (195.19 ± 51.06) and absolute scores (28.80 ± 6.20 points) of brown spots significantly decreased, while the percentiles of brown spots (38.48% ± 10.80%) significantly increased at 6 months after treatment compared with the corresponding baseline indicators (211.48 ± 50.94, 35.16 ± 6.84 points, 30.61% ± 10.27%, t = 12.73, 16.90, -15.73, respectively, all P < 0.001). All the patients experienced varying degrees of pain during the treatment, with the pain scores being 2 - 6 (3.64 ± 1.67) points, but all of them could tolerate the pain and completed the treatment. Temporary postinflammatory hyperpigmentation and hypopigmentation occurred in 9 (9.47%) and 4 (4.21%) patients respectively, and the skin color restored to normal during the 6-month follow-up. Conclusion:The 532-nm picosecond laser was safe and effective for the treatment of early-stage facial seborrheic keratosis.

AIM:To explore the potential targets and mechanisms of Angelica sinensis and Astraga-lus membranaceus ultrafiltration(RAS-AM)in the treatment of radiation induced myocardial fibrosis(RIMF)through network pharmacology combined experimental validation.METHODS:Using the TC-MSP database TCM@TAIWAN The Taiwan Tradition-al Chinese Medicine Database and TCMID Tradition-al Chinese Medicine Database screen the compo-nents and targets of RAS-AM,and use the Swiss Target Prediction database for target prediction.Obtain RIMF disease targets from Gene Cards and OMIM databases,obtain intersection targets of dis-eases and drugs through Wayne's online tool,ob-tain protein interaction relationships(PPIs)through STRING database,and use Cytoscape 3.9.1 soft-ware to construct a visualized network topology di-agram of"drug component target disease".Con-duct GO and KEGG enrichment analysis on core tar-gets through the David database,and use the mi-crobiome platform for mapping.Experimental veri-fication:Sixty Wistar rats were randomly divided in-to a blank group,a model group,a positive drug group,a RAS-AM low-dose group,a RAS-AM medi-um dose group,and a RAS-AM high-dose group.A RIMF model was established using a 38Gy dose of radiation induction,and was administered orally for 4 weeks.The general condition of the rats was also observed.After blood and heart collection in rats,HE staining was used to observe the morpho-logical changes of myocardial tissue,and ELISA and Western blot methods were used to detect key tar-gets for network pharmacology prediction.RE-SULTS:Network pharmacology analysis revealed 34 active components and 705 targets of Angelica si-nensis and Astragalus membranaceus ultrafiltra-tion,with a total of 154 targets,with IL-6,VEGFA,MMP2,MMP9,and ACE as the top five core tar-gets;GO enrichment analysis screened a total of 153 entries,and KEGG enrichment had 25 path-ways.Experimental part:HE staining results showed that the degeneration and necrosis of myo-cardial cells improved in each medication group,the infiltration of inflammatory cells in the myocar-dial interstitium decreased,and the proliferation of fibrous connective tissue in the myocardial intersti-tium decreased.ELISA and Western blot results showed that compared with the normal group,the expression of IL-6,VEGFA,and MMP-9 in the mod-el group increased.Compared with the model groupthe expression of IL-6,VEGFA,and MMP-9 in each medication group decreased to varying de-grees,in a dose-dependent manner.CONCLUSION:RAS-AM may inhibit RIMF by downregulating core targets such as IL-6,VEGFA protein,MMP-9 pro-tein,and regulating inflammatory pathways,colla-gen degradation,and other processes.
