BACKGROUND: Inflammation plays a critical role in severe cerebral venous thrombosis (CVT) pathogenesis, but the benefits of anti-inflammatory therapies remain unclear. This study aimed to investigate the association between steroid therapy combined with anticoagulation and the prognosis of acute/subacute severe CVT patients. METHODS: A prospective cohort study enrolled patients with acute/subacute severe CVT at Xuanwu Hospital (July 2020-January 2024). Patients were allocated into steroid and non-steroid groups based on the treatment they received. Functional outcomes (modified Rankin scale [mRS]) were evaluated at admission, discharge, and 6 months after discharge. Serum high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), cerebrospinal fluid (CSF) IL-6, and intracranial pressure were measured at admission and discharge in the steroid group. Fundoscopic Frisén grades were assessed at admission and 6 months after discharge. Univariate and multivariate logistic regression were used to evaluat associations between steroid use and favorable outcomes (mRS ≤2) at the 6-month follow-up. Paired tests assessed changes in hs-CRP and other variables before and after treatment, and Spearman's correlations were used to analyze relationships between these changes and functional improvements. RESULTS: A total of 107 and 58 patients in the steroid and non-steroid groups, respectively, were included in the analysis. Compared with the non-steroid group, the steroid group had a higher likelihood of achieving an mRS score of 0-2 (93.5% vs . 82.5%, odds ratio [OR] = 2.98, P  = 0.037) at the 6-month follow-up. After adjusting for confounding factors, the result remained consistent. Pulsed steroid therapy did not increase mortality during hospitalization or follow-up, nor did it lead to severe steroid-related complications (all P  >0.05). Patients in the steroid group showed a significant reduction in serum hs-CRP, IL-6, CSF IL-6, and intracranial pressure at discharge compared to at admission, as well as a significant reduction in the fundoscopic Frisén grade at the 6-month follow-up compare to at admission (all P  <0.001). A reduction in serum inflammatory marker levels during hospitalization positively correlated with improvements in functional outcomes ( P  <0.05). CONCLUSION: Short-term steroid use may be an effective and safe adjuvant therapy for acute/subacute severe CVT when used alongside standard anticoagulant treatments, which are likely due to suppression of the inflammatory response. However, these findings require further validation in randomized controlled trials. TRAIL REGISTRATION ClinicalTrials.gov , NCT05990894.

In China,stroke has become a major public health issue.In response to the growing high-risk population and the substantial health and economic burden,the National Health Commission initiated"the Stroke Prevention Project,National Health Commission"in 2021.This program aims to systematically enhance the stroke prevention and control capacities,therebyreducing the harm caused by stroke.This report offers an overview of the program's background and strategic implementation from a policy and governance perspective.

Objective To investigate the association between extensive perivascular space(EPVS)burden in different locations and ischemic stroke(IS),its subtypes,and transient ischemic attack(TIA)through Mendelian randomization(MR)analysis.Methods The summary data from large-scale Genome-wide Association Studies(GWAS)and various MR methods were employed.We applied multivariable MR to mitigate potential confounding factors and conduct sensitivity analyses to enhance result robustness.Subsequently,meta-analysis was utilized to integrate causal relationships between EPVS burden in different locations and IS from various sources.Additionally,reverse MR was employed to observe the impact of various IS types on EPVS burden.Finally,linkage disequilibrium score regression was conducted to assess genetic correlations between exposures and outcomes.Results EPVS burden in both the white matter(OR=1.12,95％CI:1.01-1.25;P=0.04)and basal ganglia(OR=1.57,95％CI:1.30-1.89;P＜0.01)are significant risk factors for IS.EPVS burden in the basal ganglia is also a risk for IS(small-vessel)(OR=4.56,95％CI:2.57-8.27;P=5.95× 10-7).After IS and TIA there seems to be a potential increase in extensive basal ganglia perivascular space burden.Conclusions Extensive white matter perivascular space burden and extensive basal ganglia perivascular space burden may serve as important indicators to predict IS.

Objective:To analyze the current status of registrations in randomized controlled trials (RCTs) of endovascular therapy for ischemic stroke.Methods:The ClinicalTrials.gov database was searched for RCTs of endovascular therapy for ischemic stroke from January 1, 1994 to June 30, 2024. The registration time, sites, sample size, complete status and design types, contents, and outcome evaluation methods of the trails were analyzed.Results:(1) A total of 195 RCTs were included. Number of RCTs registrations during 1994-2004, 2005-2014 and 2015-2024 were 2, 21 and 172, respectively. RCTs registration sites mainly concentrated in China, the United States and France, with 90 (46.1%), 29 (14.9%) and 24 (12.3%) registrations, respectively. There were 43 RCTs with sample size≤100 (22.1%), 143 RCTs with sample size of 100-1000 (73.3%), and 9 RCTs with sample size ≥1000 (4.6%). Fifty-seven RCTs were completed (29.2%, the average time from registration to trial completion was 1044 days); 91 RCTs (46.7%) were in the recruitment or pre-recruitment states; 23 RCTs (11.8%) were suspended or terminated. (2) RCTs design types included parallel design ( n=189, 96.9%), factorial design ( n=2, 1.0%), group-sequential design ( n=2, 1.0%), cross-over design ( n=1, 0.5%), and single-arm design ( n=1, 0.5%). Forty-four open trials (22.6%) and 151 blinded trials (77.4%) were recorded; among the blind trials, 108 RCTs (71.5%) were single-blind design, 19 (12.6%) were double-blind design, and 24 RCTs (15.9%) were triple-blind design. (3) A total of 69 RCTs (35.4%) focused on drug use, including 23 trails related to arterial thrombolysis drugs (mainly alteplase and tenecteplase); 67 RCTs (34.4%) were about endovascular therapy and perioperative management, among which 27 trials compared the efficacy of endovascular therapy, intravenous thrombolysis or placebo; 49 RCTs (25.1%) were about equipment use during treatment. (4) Outcome evaluation method: modified Rankin scale was most frequently used (153 RCTs), followed by National Institutes of Health Stroke Scale (100 RCTs). Conclusions:In the past decade, the number of RCTs about endovascular treatment for ischemic stroke has increased rapidly, and most of them were multi-center and blinded RCTs investigating the selection of arterial thrombolytic drugs, optimization of thrombectomy devices, and perioperative management. China is particularly prominent in this area of research.

Cardiovascular disease is the leading cause of death worldwide,with atherosclerosis(AS)-its core pathological manifestation-representing a multifactorial-driven chronic inflammatory disorder.The pathogenesis of AS involves intricate pathological mechanisms including dyslipidemia,inflammatory cascades,and plaque vulnerability,whose complexity necessitates animal models capable of accurately recapitulating specific pathological features.Genetically engineered murine models have emerged as pivotal tools for deciphering AS mechanisms,owing to their genetic manipulability,phenotypic traceability,and molecular conservation with human pathophysiology.This review provides a systematic overview of current methodologies for establishing AS mouse models,with particular emphasis on evaluating the pathological fidelity of dietary induction approaches,genetic modification strategies[notably apolipoprotein E(ApoE)-/-and low density lipoproteins receptor(LDLr)-/-models],and physical injury paradigms.
