Early Microcirculatory Dysfunction on Perfusion CT Is Related to Prognosis After Aneurysmal Subarachnoid Hemorrhage.

Microcirculatory dysfunction is an important pathophysiology mechanism of early brain injury after aneurysmal subarachnoid hemorrhage (aSAH), which contributes to poor outcomes. The study was performed in Beijing Tiantan Hospital from October 2020 to July 2023. Patients with aSAH who underwent computed tomographic perfusion (CTP) within 24 h after ictus were enrolled prospectively.

Contralateral Neurovascular Coupling in Patients with Ischemic Stroke After Endovascular Thrombectomy.

Background: Neurovascular coupling (NVC) refers to the process of aligning cerebral blood flow with neuronal metabolic demand. This study explores the potential of contralateral NVC-linking neural electrical activity on the stroke side with cerebral blood flow velocity (CBFV) on the contralesional side-as a marker of physiological function of the brain. Our aim was to examine the association between contralateral NVC and neurological outcomes in patients with ischemic stroke following endovascular thrombectomy.

Impact of Microcirculatory Dysfunction on Persistent Global Cerebral Edema After Aneurysmal Subarachnoid Hemorrhage: An Age-Stratified Analysis.

Background: Microcirculatory dysfunction is one of the most important pathophysiology mechanisms of global cerebral edema (GCE) after aneurysmal subarachnoid hemorrhage (aSAH). Data regarding the impact of microcirculatory dysfunction on persistent GCE following aSAH are currently lacking. The aim of our study was to investigate whether microcirculatory dysfunction is correlated with persistent GCE in patients with aSAH across different age groups.

Complexity of intrinsic brain activity in relapsing-remitting multiple sclerosis patients: patterns, association with structural damage, and clinical disability.

Functional plasticity has been demonstrated in multiple sclerosis (MS) studies. However, the intrinsic brain activity complexity alterations remain unclear. Here, using a coarse-graining time-series procedure algorithm, we obtained multiscale entropy (MSE) from a retrospective multi-centre dataset (208 relapsing-remitting MS patients and 228 healthy controls).

Association Between Folate Metabolism Risk, Collateral Circulation, and Hemorrhagic Risk in Moyamoya Disease.

Methylenetetrahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) polymorphisms are known risk factors for vascular diseases due to the impact on folate metabolism dysfunction and homocysteine (Hcy) accumulation. This study aimed to investigate the association between folate metabolism risk and hemorrhagic risk in moyamoya disease (MMD). In this prospective study, we enrolled 350 MMD patients with complete genotype data for MTHFR and MTRR.

Dual antiplatelet therapy with ticagrelor vs clopidogrel in patients with TIA or minor stroke with or without symptomatic carotid artery stenosis: a post hoc analysis of the CHANCE-2 trial.

Nerelimomab Alleviates Capsaicin-Induced Acute Lung Injury by Inhibiting TNF Signaling and Apoptosis.

Capsaicin is commonly used as a flavoring and a riot control agent. However, long-term exposure or high doses can cause acute lung injury in military and police personnel. The mechanisms underlying capsaicin-induced pulmonary toxicity remain unclear.

GP73 reinforces cytotoxic T-cell function by regulating HIF-1α and increasing antitumor efficacy.

Background: Immunotherapy that targets immune checkpoints has achieved revolutionary success, but its application in solid tumors remains limited, highlighting the need for reliable enhancement of the efficacy of immunotherapy. Golgi protein 73 (GP73), a Golgi membrane protein, has been implicated in various cellular processes, including immune regulation. Recent studies suggested that GP73 may play a role in modulating the immune response in patients with cancer.

Advances in research on metabolic dysfunction-associated steatotic liver disease.

The global increase in obesity-related metabolic disorders has led to metabolic dysfunction-associated steatotic liver disease (MASLD) emerging as one of the most prevalent chronic liver disease worldwide. Despite growing concerns, the exact pathogenesis of MASLD remains unclear and no definitive treatments have been made available. Consequently, the need for comprehensive research on MASLD is more critical than ever.

Understanding Chinese Early-Career Neurosurgeons' Professional Identity Construction as Clinician-Researchers.

Background: Medical professionals with both M.D. and Ph.

Gain-of-function ANXA11 mutation cause late-onset ALS with aberrant protein aggregation, neuroinflammation and autophagy impairment.

Mutations in the ANXA11 gene, encoding an RNA-binding protein, have been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS), but the underlying in vivo mechanisms remain unclear. This study examines the clinical features of ALS patients harboring the ANXA11 hotspot mutation p.P36R, characterized by late-onset motor neuron disease and occasional multi-system involvement.

Oxygenation targets for endovascular therapy in acute ischemic stroke patients (Oxy-TARGET): protocol for a single-centre, open-label randomised controlled trial.

Introduction: Preclinical studies have shown that oxygen therapy can improve ischaemic brain tissue oxygen tension, reduce reperfusion injury after revascularisation, promote neuroregeneration and inhibit inflammatory responses potentially exerting a beneficial effect after endovascular treatment (EVT) in patients with acute ischaemic stroke (AIS). However, the optimal fraction of inspired oxygen (FiO) during EVT under general anaesthesia is currently unknown. Therefore, we are conducting a randomised controlled trial (RCT) to evaluate the impact of high-concentration oxygen vs low-concentration normobaric oxygen on early neurological function after EVT.

SEEG seizure onset patterns in mesial temporal lobe epilepsy: A cohort study with 76 patients.

Objectives: In the present study with a large cohort, we aimed to characterize intracerebral seizure onset patterns (SOP) of mesial temporal lobe epilepsy (mTLE), with or without hippocampal sclerosis (HS) as identified via magnetic resonance imaging (MRI).

Methods: We retrospectively analyzed 255 seizures of 76 consecutive patients with mTLE explored by stereoelectroencephalography (SEEG), including HS-mTLE (n = 52) and non-HS- mTLE (n = 24). Relevant results were obtained by a combination of spectral analysis and manual review.

Associations between stress hyperglycemia and outcomes in patients with ischemic stroke and TIA: the data comes from the Third China National Stroke Registry (CNSR-III).

In the acute stage of stroke, stress hyperglycemia is common in both diabetic and nondiabetic patients. The associations between stress hyperglycemia and functional outcomes, as well as stroke recurrence were heterogeneous in previous studies. We aimed to demonstrate these associations in a general population of patients with ischemic stroke and transient ischemic attack (TIA).

Recent advances in mRNA-based therapeutics for neurodegenerative diseases and brain tumors.

Messenger RNA (mRNA) therapy is an innovative approach that delivers specific protein-coding information. By promoting the ribosomal synthesis of target proteins within cells, it supplements functional or antigenic proteins to treat diseases. Unlike traditional gene therapy, mRNA does not need to enter the cell nucleus, reducing the risks associated with gene integration.

Enhancing prognosis in multiple myeloma bone disease: insights from a retrospective analysis of surgical interventions.

Background: Multiple myeloma (MM) is a hematological malignancy characterized by bone marrow infiltration and osteolytic tumor formation. Despite advancements in the treatment of this disease, MM remains incurable and often leads to complications, such as multiple myeloma bone disease (MMBD). Surgical intervention is frequently necessary to manage symptoms associated with bone disease, including pain and fractures.
