Longer procedure time (PT) predicts worse prognosis after endovascular treatment (EVT) in acute vertebrobasilar artery occlusion (VBAO), but it remains unknown whether it is worth pursuing recanalization when the PT is obviously extended. Patients with acute VBAO who received EVT were retrospectively enrolled from 21 stroke centers in China from December 2015 to December 2018. Multivariable logistic analysis was performed to analyze the associations of PT with favorable outcome (defined as modified Rankin Scale score of 0 to 3) and mortality at 90 days.

Background Endovascular thrombectomy (EVT) is an effective method for vertebrobasilar artery occlusion (VBAO) in patients with moderate to severe deficits but has unclear benefits in patients with low National Institutes of Health Stroke Scale (NIHSS) scores at hospital admission. Purpose To compare the clinical outcomes of best medical management (BMM) alone versus BMM and early EVT (door-to-puncture time [DPT] ≤ 120 minutes) versus BMM and late EVT (DPT > 120 minutes) in patients with VBAO who have NIHSS scores of 10 or less at admission. Materials and Methods This retrospective study evaluated patients with VBAO and admission NIHSS score of 10 or less who were seen at 65 stroke centers in China from December 2015 to June 2022.

Article Synopsis
  • - Niemann-Pick disease Type C (NPC) is a neurodegenerative disorder caused by mutations in the NPC1 gene, resulting in cholesterol buildup in cells, particularly affecting microglial function.
  • - In neonatal Npc1 mutant mice, researchers observed reactive microglia with increased CD68 and phagocytic activity, indicating disrupted TREM2-mTOR signaling pathways.
  • - The study found that deleting the Trem2 gene in Npc1-deficient BV2 cells partially restored microglial function, suggesting that NPC1 loss alters microglial morphology and lysosomal function via TREM2-mTOR signaling.

Metal peroxide nanomaterials as efficient hydrogen peroxide (HO) self-supplying agents have attracted the attention of researchers for antitumor treatment. However, relying solely on metal peroxides to provide HO is undoubtedly insufficient to achieve optimal antitumor effects. Herein, we construct novel hyaluronic acid (HA)-modified nanocomposites (MgO/Pd@HA NCs) formed by decorating palladium nanoparticles (Pd NPs) onto the surfaces of a magnesium peroxide (MgO) nanoflower as a highly effective nanoplatform for the tumor microenvironment (TME)-responsive induction of ferroptosis in tumor cells and tumor photothermal therapy (PTT).

Objectives: A higher reperfusion grade after endovascular thrombectomy (EVT) is associated with a good prognosis. However, the effect of the number of retrievals has not yet been investigated in vertebrobasilar occlusion (VBAO). Therefore, the aim of this study was to investigate whether to continue retrieval after early modified thrombolysis in cerebral infarction (mTICI) 2b to achieve a better reperfusion grade.

This study aimed to explore the topographic features of thalamic subregions, functional connectomes and hierarchical organizations between thalamus and cortex in poststroke fatigue patients. We consecutively recruited 121 acute ischemic stroke patients (mean age: 59 years) and 46 healthy controls matched for age, sex, and educational level. The mean age was 59 years (range 19-80) and 38% of acute stroke patients were females.

Background: Neurological recovery after endovascular treatment (EVT) for large vessel occlusion stroke often has diverse timelines. Understanding the temporal progression of functional independence after EVT, especially delayed functional independence (DFI) and highly delayed functional independence (HDFI), in patients who do not improve early is essential for prognostication and rehabilitation. We aimed to analyze the prevalence and predictors of DFI and HDFI after EVT in acute vertebrobasilar artery occlusions (VBAO).

Network pharmacology is widely used to predict the mechanism of traditional Chinese medicines (TCM), but the framework in traditional network pharmacology analysis ignores the relationship between the concentration of components and drug efficacy. Lanqin oral solution (LOS) is a TCM formulation that widely used in the clinical treatment of pharyngitis, but its pharmacodynamic mechanism is still unknown. The present study was designed to elaborate the anti-inflammatory mechanism of LOS based on the quality markers (Q-markers).
