Objective To explore the correlation between stroke etiology and clinical and imaging features in patients with acute ischemic stroke(AIS)due to large vessel occlusion treated by intravascular thrombectomy.Methods A total of 213 patients with AIS and endovascular embolectomy in our hospital from Oct.2016 to Jun.2018 were enrolled retrospectively.According to the etiological classification criteria of Trial of Org 10172 in Acute Stroke Treatment(TOAST),there were 116 cases of cardioembolism and 97 cases of non-cardioembolism.Multivariate logistic regression analysis was used to screen the clinical and imaging characteristics for identifying cardioembolism and non-cardioembolism.Results Compared with non-cardioembolism AIS,cardioembolism AIS was associated with higher NIHSS scores(adjusted odds ratio[OR]=1.09,95%confidence interval[95%CI]1.01-1.18,P=0.02),atrial fibrillation(adjusted OR=76.46,95%CI 26.75-218.51,P＜0.01),absence of hypertension(adjusted OR=0.32,95%CI 0.12-0.84,P=0.02),antiplatelet drug use(adjusted OR=5.03,95%CI 1.22-20.63,P=0.03),shorter onset-to-puncture time(adjusted OR=0.998,95%CI 0.996-1.000,P=0.04),and presence of hyperdense artery sign(HAS)(adjusted OR=4.45,95%CI 1.47-13.49,P=0.01).Conclusion There are some differences in clinical and imaging characteristics between patients with cardioembolism and non-cardioembolism AIS.The occurrence of HAS suggests a higher probability of cardioembolism in AIS patients.

Objective:To explore the mediating effect of self-rated health status between living space and social frailty of the elderly in community, and to provide reference for intervention strategies.Methods:From December 2023 to March 2024, 550 community elderly in Yandun Community, Yicheng Community and Binhu Community in Baohe District of Hefei City were selected as the research objects by convenient sampling method. The general information questionnaire, self-rated health questionnaire, social frailty index and living space assessment scale were used to investigate a cross-sectional survey. Spearman correlation analysis was used to explore the correlation between self-rated health, living space and social frailty of community elderly. Bootstrap method was used to test the mediating effect.Results:A total of 542 valid questionnaires were collected. Among the 542 elderly residents in the community, aged 65-94 (71.69 ± 6.54) years, there were 267 males and 275 females. Among the 542 community elderly, the self-rated health score, living space score and social frailty index were (2.52 ± 0.95), (73.39 ± 16.77) and 0.0 (0.0, 3.0), respectively. Spearman analysis showed that the total score of living space was negatively correlated with the scores of self-rated health and social frailty ( r=-0.477, -0.538, both P<0.01), and the score of self-rated health was positively correlated with the score of social frailty ( r=0.711, P<0.01).The mediating effect results showed that the living space could play a partial mediating effect on social frailty through the mediating variable of self-rated health (-0.028), accounting for 49.12% of the total effect. Conclusions:The self-rated health status of the elderly in the community has an indirect mediating effect between living space and social frailty. Medical workers should take the improvement of the living space mobility of the elderly as the starting point, and improve their self-rated health level through diversified intervention means, so as to reduce the occurrence of social frailty and promote active aging.

This study investigated the incidence,prevention and control measures,diagnostic and treatment methods,and treatment costs of hoof diseases in dairy cows across 87 large-scale farms,aiming to provide a scientific basis and new insights for the treatment and prevention of hoof disea-ses in dairy herds.The results showed that the incidence rate of lameness in most farms was con-trolled between 3％and 7％,with a cure rate above 85％.The importance ranking of prevention and control measures was as follows:hoof trimming＞leveling the ground＞disinfection＞regular foot baths＞manure removal＞locomotion(lameness)scoring.The importance ranking of treat-ment measures was:hoof trimming＞disinfection and astringents＞anti-inflammatory treatment＞antibiotics＞block application＞traditional Chinese medicine(fire therapy).Economic analysis showed that the treatment cost of lameness was closely related to the incidence rate,with higher treatment expenses observed in farms with higher incidence rates.Farms with higher individual milk yields typically had more efficient disease management strategies,leading to lower treatment costs.Large-scale farms should continuously optimize management practices to reduce the occur-rence of lameness and improve overall farm efficiency by using effective treatment strategies.

Pulmonary arterial hypertension(PAH)is a serious and fatal cardiovascular disease that significantly affects patients'quality of life and survival.Current treatments offer some relief but have limited effectiveness and notable side effects.Sotatercept,as a novel drug,modulates the transforming growth factor-β(TGF-β)signaling pathway and shows promising therapeutic effects in PAH.By summarizing the pharmacological mechanisms and clinical research progress of sotatercept in PAH,assessing its application prospects,and analyzing future research directions in the light of current clinical research results,we provide an important perspective for understanding the clinical application of this drug in China,with a view to promoting its promotion and application in China.

Objective:To explore the latent categories and influencing factors of health activation among community-dwelling older adults with chronic diseases.Methods:Older patients with chronic diseases attending three community health centers in Hefei City from August to December 2023 were selected for the study using the convenience sampling method. The survey utilized the General Information Questionnaire, Consumer Health Activation Index, Chinese version of the Life-Space Assessment, Social Support Rating Scale, and Simplified Coping Style Questionnaire. Mplus 8.3 software was applied for latent profile analysis to examine patients' health activation, and unordered multicategory Logistic regression was used to explore the factors influencing different categories of health activation.Results:A total of 382 questionnaires were distributed, and 368 valid questionnaires were recovered, with a valid recovery rate of 96.34%. Three latent categories of health activation existed in community-dwelling older adults with chronic diseases, which were named as low health activation-high efficiency-coping inability group (16.85%, 62/368) , medium health activation group (27.99%, 103/368) , and high activation perception-action group (55.16%, 203/368) . Multicategory logistic regression analysis indicated that place of residence, age, self-rated health status, life space, social support, and active coping strategies were significant factors influencing the health activation of different latent categories of community-dwelling older adults with chronic diseases (all P<0.05) . Conclusions:The health activation of community-dwelling older adults with chronic diseases can be classified into three latent categories. Primary healthcare providers should identify the characteristics of patients in different categories and implement targeted nursing interventions to enhance their health activation levels.

Background::Homoharringtonine (HHT) is an effective anti-inflammatory, anti-viral, and anti-tumor protein synthesis inhibitor that has been applied clinically. Here, we explored the therapeutic effects of HHT in a mouse heart transplant model.Methods::Healthy C57BL/6 mice were used to observe the toxicity of HHT in the liver, kidney, and hematology. A mouse heart transplantation model was constructed, and the potential mechanism of HHT prolonging allograft survival was evaluated using Kaplan–Meier analysis, immunostaining, and bulk RNA sequencing analysis. The HHT-T cell crosstalk was modeled ex vivo to further verify the molecular mechanism of HHT-induced regulatory T cells (Tregs) differentiation. Results::HHT inhibited the activation and proliferation of T cells and promoted their apoptosis ex vivo. Treatment of 0.5 mg/kg HHT for 10 days significantly prolonged the mean graft survival time of the allografts from 7 days to 48 days ( P <0.001) without non-immune toxicity. The allografts had long-term survival after continuous HHT treatment for 28 days. HHT significantly reduced lymphocyte infiltration in the graft, and interferon-γ-secreting CD4 + and CD8 + T cells in the spleen ( P <0.01). HHT significantly increased the number of peripheral Tregs (about 20%, P <0.001) and serum interleukin (IL)-10 levels. HHT downregulated the expression of T cell receptor (TCR) signaling pathway-related genes ( CD4, H2-Eb1, TRAT1, and CD74) and upregulated the expression of IL-10 and transforming growth factor (TGF) -β pathway-related genes and Treg signature genes ( CTLA4, Foxp3, CD74, and ICOS). HHT increased CD4 + Foxp3 + cells and Foxp3 expression ex vivo, and it enhanced the inhibitory function of inducible Tregs. Conclusions::HHT promotes Treg cell differentiation and enhances Treg suppressive function by attenuating the TCR signaling pathway and upregulating the expression of Treg signature genes and IL-10 levels, thereby promoting mouse heart allograft acceptance. These findings may have therapeutic implications for organ transplant recipients, particularly those with viral infections and malignancies, which require a more suitable anti-rejection medication.
