Chinese stroke association guidelines on reperfusion therapy for acute ischaemic stroke 2024.

Background: Stroke remains a major global health challenge, with China experiencing a significant burden due to its high incidence and severe outcomes. Reperfusion therapies, such as intravenous thrombolysis and endovascular thrombectomy, have shown substantial benefits in improving early outcomes for ischaemic stroke. Recent clinical trials have validated the safety and efficacy of a broader range of thrombolytic agents and expanded the eligible patient populations for both intravenous thrombolysis and mechanical thrombectomy.

Case report: paraneoplastic cerebellar degeneration associated with anti-Yo antibody successfully treated with ofatumumab.

Paraneoplastic cerebellar degeneration (PCD) with anti-Yo antibodies represents a rare immune-mediated paraneoplastic neurological syndrome. Its diagnosis and management remain clinically challenging. Here, we present a case of PCD with confirmed anti-Yo antibodies, validated through anti-cerebellar degeneration protein 2 (CDR2) and anti-CDR2-like antibodies detection, which demonstrated a favorable response to ofatumumab therapy.

Oxidative metabolism mechanism of terpenoid compound ZQ-8 by cytochrome P450 enzyme in Helicoverpa armigera.

In our previous research, we identified that treatment of Helicoverpa armigera with ZQ-8 led to upregulation of CYP450 genes. To clarify the metabolic pathway of ZQ-8, this study analyzed the expression of CYP450 genes and proteins in H. armigera after ZQ-8 treatment through transcriptomics and proteomics.

Beyond low-density lipoprotein cholesterol levels: Impact of prior statin treatment on ischemic stroke outcomes.

Although essential for cardiovascular therapy, the pleiotropic effects of statins on ischemic stroke lack clinical evidence. This study examined the effects of statins beyond low-density lipoprotein cholesterol (LDL-C) levels on mortality and stroke severity. A total of 825,874 patients with ischemic stroke were included in this study, of whom 125,650 statin users were 1:1 matched with non-users based on their LDL-C levels (±0.

Methods: A total of 60 patients with PD with depression hospitalised between February 2022 and February 2023 were selected using a convenience sampling method. They were divided into a study group (30 cases) and control group (30 cases) using the random number table method.

Duration of Benefit and Risk of Dual Antiplatelet Therapy up to 72 Hours After Mild Ischemic Stroke and Transient Ischemic Attack.

Background And Objectives: Clopidogrel-aspirin initiated within 72 hours of symptom onset is effective in patients with mild ischemic stroke or transient ischemic attack (TIA) in the Intensive Statin and Antiplatelet Therapy for Acute High-risk Intracranial or Extracranial Atherosclerosis (INSPIRES) trial. Uncertainties remain about the duration of the treatment effect. This study aimed to assess duration of benefit and risk of clopidogrel-aspirin in these patients.

Glycated albumin levels are associated with adverse stroke outcomes in patients with acute ischemic stroke in China.

Background And Aim: Glycated albumin (GA) is a biomarker monitoring glycemia 2-4 weeks before stroke onset. This study was designed to explore the association between GA levels with poststroke outcomes in patients with acute ischemic stroke or transient ischemic attack (TIA).

Method: Participants with ischemic stroke or TIA who had a baseline GA measurement were included in the Third China National Stroke Registry study.

Effects of different tooth movement patterns and aligner thicknesses on maxillary arch expansion with clear aligners: a three-dimensional finite element study.

Objectives: The objective of this study was to investigate the biomechanical effects of different tooth movement patterns and aligner thicknesses on teeth and periodontal tissues during maxillary arch expansion with clear aligners, to facilitate more precise and efficient clinical orthodontic treatments.

Methods: Three-dimensional models including teeth, maxilla, periodontal ligament, and aligner were constructed and subjected to finite element analysis. Tooth displacement trends and periodontal ligament stresses were measured for seven tooth displacement patterns (divided into three categories including overall movement of premolars and molars with gradually increasing molar expansion in each step; distributed movement of premolars and molars; and alternating movement between premolars and molars at intervals) and two aligner thicknesses (0.

Comprehensive toxicological, metabolomic, and transcriptomic analysis of the biodegradation and adaptation mechanism by SL-6 to diuron.

Biodegradation was considered a promising and environmentally friendly method for treating environmental pollution caused by diuron. However, the mechanisms of biodegradation of diuron required further research. In this study, the degradation process of diuron by SL-6 was systematically investigated.

Importance: Comparisons are limited for immediate-intensive and delayed-intensive statin for secondary stroke prevention and neuroprotection in patients with acute mild ischemic stroke or transient ischemic attack (TIA) from atherosclerosis.

Objective: To estimate whether immediate-intensive statin therapy is safe and can lower the risk of recurrent stroke compared with delayed-intensive statin in patients with acute mild ischemic stroke or high-risk TIA from atherosclerosis.

Design, Setting, And Participants: The Intensive Statin and Antiplatelet Therapy for High-Risk Intracranial or Extracranial Atherosclerosis (INSPIRES) trial, a double-blind, placebo-controlled, 2 × 2 factorial, randomized clinical trial enrolled patients from September 2018 to October 2022.

The FAITHS Model Predicts Functional Disability in Patients With Acute Ischemic Stroke.

The present study aimed to develop a model to predict functional disability at 3 months in patients with acute ischemic stroke (AIS) ( = 5,406). The primary outcome was functional disability (modified Rankin Scale [mRS] >2) at 3 months. A prediction model including blood biomarkers was developed based on a multivariable logistic regression model, which was internally validated by the 100-time bootstrap method.

Rationale and design of Treatment of Acute Ischaemic Stroke with Edaravone Dexborneol II (TASTE-2): a multicentre randomised controlled trial.

Background: Edaravone dexborneol is believed to be a novel cytoprotective drug, demonstrating a synergistic combination of antioxidative and anti-inflammatory properties in animal models. The Treatment of Acute Ischaemic Stroke with Edaravone Dexborneol (TASTE) trial demonstrated its superior efficacy over edaravone alone for acute ischaemic stroke (AIS) patients. However, its efficacy in individuals undergoing endovascular therapy (EVT) remains uncertain.

Effects of subthalamic nucleus deep brain stimulation using different frequency programming paradigms on axial symptoms in advanced Parkinson's disease.

Background: In advanced Parkinson's disease (PD), axial symptoms are common and can be debilitating. Although deep brain stimulation (DBS) significantly improves motor symptoms, conventional high-frequency stimulation (HFS) has limited effectiveness in improving axial symptoms. In this study, we investigated the effects on multiple axial symptoms after DBS surgery with three different frequency programming paradigms comprising HFS, low-frequency stimulation (LFS), and variable-frequency stimulation (VFS).

Implementation of early prophylaxis for deep-vein thrombosis in intracerebral hemorrhage patients: an observational study from the Chinese Stroke Center Alliance.

Background: There is substantial evidence to support the use of several methods for preventing deep-vein thrombosis (DVT) following intracerebral hemorrhage (ICH). However, the extent to which these measures are implemented in clinical practice and the factors influencing patients' receipt of preventive measures remain unclear. Therefore, we aimed to evaluate the rate of the early implementation of DVT prophylaxis and the factors associated with its success in patients with ICH.

Ratio-fluorescence detection of tert-butylhydroquinone based on non-conjugated polymer dots and gold nanoclusters.

A novel ratiometric fluorescent probe based on non-conjugated polymer dots (NCPDs) and gold nanocluster (AuNCs) was constructed to determine tert-butylhydroquinone (TBHQ). The probe exhibited dual emission peaks at 480 nm and 630 nm under 370 nm excitation. The fluorescence of AuNCs was quenched by TBHQ due to strong electrostatic interactions, whereas the emission of NCPDs increased.
