Aim To explore the mechanism by which dioscin regulates IL-17+γδT cells in the treatment of arthritis.Methods A collagen-induced arthritis(CIA)model was established in DBA/1 mice using bovine type Ⅱ collagen.The mice were randomly divid-ed into the CIA model group,methotrexate(MTX)positive control group,and dioscin low-dose(Dioscin-L),medium-dose(Dioscin-M),and high-dose(Dios-cin-H)groups.After intervention,the therapeutic effects were evaluated using scoring methods.Joint pathological damage was analyzed by hematoxylin and eosin(HE)staining.The levels of anti-collagen-spe-cific antibodies and the pro-inflammatory cytokine IL-17 were measured by ELISA.The expressions of γδT cells and their subtypes,as well as the secretion level of IL-17,were detected by flow cytometry.Results Dioscin significantly reduced the arthritis severity score in collagen-induced arthritis(CIA)mice,alleviated joint pathological damage,inhibited the production of IL-17 by splenic lymphocytes and the levels of anti-col-lagen-specific antibodies total IgG and IgG3,and de-creased the proportion of γδT cells in the lymph nodes,splenic γδT cells,and the Vδ4+T-cell subset.The level of IL-17 produced by the Vδ4 subtype in the lymph nodes of the intervention groups was lower than that in the model group,but the difference was not sta-tistically significant.Conclusion Dioscin has signifi-cant therapeutic effect on CIA,and its mechanism may be through the inhibition of γδT cells,but it is unlikely to be related to IL-17 derived from γδT cells.

Objectives:To investigate the distribution and change of the burden of cardiovascular diseases attributable to tobacco consumption in China and the world from 1990 to 2021.Methods:Based on Global Burden of Disease(GBD)2021 database,age standardized mortality and age standardized disability-adjusted life year(DALY)rates and estimated annual percentage change(EAPC)from cardiovascular disease(including ischemic heart disease,stroke,atrial fibrillation and flutter,aortic aneurysm,peripheral artery disease)attributable to tobacco consumption were analyzed.The association of the human development index(HDI)and social demographic index(SDI)with age-standardized mortality was also analyzed.Results:Compared to 1990,the global burden of cardiovascular diseases attributable to smoking declined in 2021,age-standardized mortality decreased from 57.2/100 000 to 26.3/100 000(EAPC=-1.81%,95% CI:-2.00% to-1.63% ).The global burden of cardiovascular diseases attributable to second-hand smoke also decreased,age-standardized mortality decreased from 11.4/100 000 to 8.3/100 000(EAPC=-1.72%,95% CI:-1.91% to-1.53% ).In China,the burden of cardiovascular diseases attributable to smoking also decreased,age-standardized mortality decreased from 52.2/100 000 to 39.6/100 000(EAPC=-1.23%,95% CI:-1.44%-1.02% );the burden of cardiovascular diseases attributable to second-hand smoke decreased,age-standardized mortality decreased from 15.3/100 000 to 14.7/100 000(EAPC=-1.26%,95% CI:-1.63% to-0.90% ).Notably,the decrease in cardiovascular diseases burden attributable to second-hand smoke among Chinese women was more significant than the global level,the age-standardized mortality rate of Chinese women decreased from 17.9/100 000 to 14.5/100 000(EAPC=-2.24%,95% CI=-2.78%～-1.86% ).Among the five types of cardiovascular diseases attributable to tobacco consumption globally and in China,the age-standardized mortality and age-standardized DALY rates of aortic aneurysm,ischemic heart disease and peripheral artery disease were higher.Globally,ischaemic heart disease is the leading cause of death,accounting for 60.2% in 1990 and 61.7% in 2021,while stroke is the leading cause of death in China,accounting for 68.1% and 51.4% in 1990 and 2021,respectively.In addition,HDI and SDI are the two main factors affecting the disease burden.In regions and countries with SDI>7.2,age standardized mortality is below our forecast line.In the later part of the forecast,China's age standardized mortality showed a downward trend,possibly due to changes in tobacco control measures.Conclusions:Over the past 30 years,the burden of cardiovascular diseases attributed to tobacco consumption has decreased globally and in China.The decline in disease burden has been most pronounced among women.However,in countries and regions with an SDI below 7.2,the burden of disease remains significant high.Therefore,it is necessary to take tobacco control measures in key regions(China,East Asia,Central Europe,Central Asia and Southeast Asia)to actively reduce smoking rates and exposure to secondhand smoke in public places,so as to reduce the burden of cardiovascular diseases.

OBJECTIVE: Circadian rhythm disruption (CRD) is a risk factor that correlates with poor prognosis across multiple tumor types, including hepatocellular carcinoma (HCC). However, its mechanism remains unclear. This study aimed to define HCC subtypes based on CRD and explore their individual heterogeneity. METHODS: To quantify CRD, the HCC CRD score (HCCcrds) was developed. Using machine learning algorithms, we identified CRD module genes and defined CRD-related HCC subtypes in The Cancer Genome Atlas liver HCC cohort (n = 369), and the robustness of this method was validated. Furthermore, we used bioinformatics tools to investigate the cellular heterogeneity across these CRD subtypes. RESULTS: We defined three distinct HCC subtypes that exhibit significant heterogeneity in prognosis. The CRD-related subtype with high HCCcrds was significantly correlated with worse prognosis, higher pathological grade, and advanced clinical stages, while the CRD-related subtype with low HCCcrds had better clinical outcomes. We also identified novel biomarkers for each subtype, such as nicotinamide n-methyltransferase and myristoylated alanine-rich protein kinase C substrate-like 1. CONCLUSION We classify the HCC patients into three distinct groups based on circadian rhythm and identify their specific biomarkers. Within these groups greater HCCcrds was associated with worse prognosis. This approach has the potential to improve prediction of an individual's prognosis, guide precision treatments, and assist clinical decision making for HCC patients.

A comprehensive phytochemical investigation of the leaves and twigs of Physalis angulata. var. villosa resulted in the isolation of 23 withanolide derivatives, including one novel 13,20-γ-lactone withanolide derivative (1) and three new withanolide derivatives (2-4). Architecturally, physalinin A (1) represents the first identified type B withanolide featuring a 13,20-γ-lactone moiety. The molecular structures of all isolates were elucidated using an integrated approach combining nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS), infrared (IR) spectroscopy, and quantum chemical calculations to confirm structural assignments. The antiproliferative activities of all isolated withanolides were evaluated against four human cancer cell lines (HEL, HCT-116, Colo320DM, and MDA-MB-231). Among them, eight derivatives (2, 5-8, 14, 15, and 23) exhibited significant inhibitory effects, with half-maximal inhibitory concentration (IC₅₀) values of 0.18 ± 0.03 to 17.02 ± 0.21 μmol·L^-1. Structure-activity relationship (SAR) analysis suggested that the presence of an epoxide ring enhances anticancer activity, potentially through increased reactivity or specific interactions with molecular targets involved in cancer progression. These findings underscore the pharmacological potential of withanolides as promising lead compounds for the development of novel anticancer therapeutics.

OBJECTIVE: Hepatocellular carcinoma (HCC) is sensitive to ferroptosis, a new form of programmed cell death that occurs in most tumor types. However, the mechanism through which ferroptosis modulates HCC remains unclear. This study aimed to investigate the oncogenic role and prognostic value of FANCD2 and provide novel insights into the prognostic assessment and prediction of immunotherapy. METHODS: Using clinicopathological parameters and bioinformatic techniques, we comprehensively examined the expression of FANCD2 macroscopically and microcosmically. We conducted univariate and multivariate Cox regression analyses to identify the prognostic value of FANCD2 in HCC and elucidated the detailed molecular mechanisms underlying the involvement of FANCD2 in oncogenesis by promoting iron-related death. RESULTS: FANCD2 was significantly upregulated in digestive system cancers with abundant immune infiltration. As an independent risk factor for HCC, a high FANCD2 expression level was associated with poor clinical outcomes and response to immune checkpoint blockade. Gene set enrichment analysis revealed that FANCD2 was mainly involved in the cell cycle and CYP450 metabolism. CONCLUSION To the best of our knowledge, this is the first study to comprehensively elucidate the oncogenic role of FANCD2. FANCD2 has a tumor-promoting aspect in the digestive system and acts as an independent risk factor in HCC; hence, it has recognized value for predicting tumor aggressiveness and prognosis and may be a potential biomarker for poor responsiveness to immunotherapy.
