BACKGROUND: Neuroinflammation and oxidative stress after traumatic brain injury (TBI) can further lead to neuronal apoptosis, which plays a crucial role in the process of neuron death. Curcumin, which is derived from the rhizome of the Curcuma longa plant, has multiple pharmacological effects. OBJECTIVE: The objective of this study was to investigate whether curcumin treatment has neuroprotective effects after TBI, and to elucidate the underlying mechanism. METHODS: A total of 124 mice were randomly divided into 4 groups: Sham group, TBI group, TBI+Vehicle group, and TBI+Curcumin group...

BACKGROUND: Ischemic stroke is a major cause of death and disability worldwide and results from inadequate cerebrovascular blood supply; mitochondrial dysfunction plays an essential role in its pathogenesis. DL-3-n-butylphthalide (NBP) is an effective medicine for ischemic stroke that reduces cell apoptosis and improves long-term prognosis. OBJECTIVE: Whether and how NBP regulates mitochondria-associated apoptosis in cerebral ischemia-reperfusion injury remains unclear...

Apolipoprotein E4 (APOE4) is one of the primary genetic risk factors for late-onset of Alzheimer's disease (AD). While its primary function is to transport cholesterol, it also regulates metabolism, aggregation, and deposition of amyloid-β (Aβ) in the brain. The disruption in the generation and removal of Aβ in the brain is the primary cause of memory and cognitive loss and thus plays a significant role in the development of AD. In several prior genetic investigations, the APOE4 allele has been linked to higher susceptibility to severe acute respiratory syndrome (SARS-CoV-2) infection and COVID-19 mortality...

Background: Paeonol (Pae), the main active compound of the root of Paeonia albiflora, is efficacious in treating atherosclerosis (AS). Endothelial dysfunction is throughout the pathological progression of AS. It is expected that inhibition of Endothelial-to-mesenchymal transition (EndMT) will be a key target for AS treatment. Objective: In this study, we investigated the molecular mechanism of the regulatory effect of Pae on EndMT in human umbilical vein endothelial cells (HUVECs). Methods: Cell cytotoxicity, proliferation, and migration were detected by CCK-8, the wound healing assay, and EdU staining, respectively...

BACKGROUND: Neuropathic pain originating from a dysfunction in the nervous system is often intractable and chronic. Recently, several studies using nanoparticles suggested a new way to control neuropathic pain. This study intended to explore the potential neuroprotective effect of Cerium Oxide Nanoparticles (CNPs) synthesized by pullulan in neuropathic pain in rats. METHODS: On the right common sciatic nerve of male Wistar rats, the chronic constriction injury (CCI) procedure was used to establish a neuropathic pain model...

Several pieces of evidence suggest that serum lactate hydrogenase (LDH) level is associated with the pathological process of delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH). This research aimed to investigate the associations of serum LDH level with the occurrence of DCI in aSAH patients. </P> <P> Methods: A total of 122 patients diagnosed with aSAH within 72h of onset were retrospectively enrolled. The serum levels of LDH between 7:00-8:00 am on day 1, day 3 and day 7, patients' demographics, and clinical features were collected...

Recurrent ischemic stroke (IS) is one of the leading causes of disability and death worldwide. Patients with recurrent IS, in comparison with survivors of the initial non-cardiogenic IS, have more serious neurological deficit and longer average hospital stay as well as heavier family and socio-economic burden. Therefore, recurrent IS is a major challenge that we urgently need to address. The recurrence rate of non-cardiogenic IS is not zero, and even shows an increasing trend over a long period of time, despite receiving evidence-based management in accordance with guideline, indicating that patients suffering from non-cardiogenic IS and who are receiving the optimal management remain at considerable residual risks (RRs) responsible for the recurrence of cerebrovascular events...

Background- A certain number of patients with single subcortical small infarction (SSSI) in the lenticulostriate artery (LSA) territory present with early neurological deterioration (END). Objective-We sought to identify more specific predicting imaging marker for END in lenticulostriate SSSI patients. Methods-We screened patients in a prospective hospital-based registry of stroke in the first Affiliated Hospital of Zhengzhou University from January 2015 to December 2020. Lesion locations were defined as posterior type when more than half of the lesion was located in the posterior part of the corona radiata divided by the midline, which was drawn between the tangents of the anterior and posterior horns of the lateral ventricle and was adjacent to the lateral ventricle at the same time...

BACKGROUND: The cognitive impairment after acute intracerebral hemorrhage (ICH) is common. While, the evidence of early cognitive impairment at acute stage after ICH are limited. We determined the frequency and risk factors of early cognitive impairment at acute stage and investigated its association with delayed cognitive impairment after ICH. METHODS: A total of 208 patients with acute ICH were enrolled from January 2017 to February 2019. Cognitive function was assessed during the acute stage and at follow-up using Montreal Cognitive Assessment (MoCA) score...

OBJECTIVE: Mechanical thrombectomy (MT) is an effective treatment for large vessel occlusion (LVO) with a high successful recanalization (SR) rate. However, MT fails in a proportion of patients, leading to poor clinical outcomes. We analyzed the factors associated with the failure of MT. METHODS: A total of 648 consecutive patients with MT were enrolled. MT failure was defined as 0,1, or 2a of modified Thrombolysis in Cerebral Infarction (mTICI) grade. Failed MTs were divided into 3 categories, reaching failure, passage failure, and recanalization failure (RF)...

BACKGROUND: Depressive symptoms are one of the main clinical features of the cerebral small-vessel disease (CSVD). However, the pathogenesis of depressive symptoms of CSVD has not been fully studied, and a lack of effective diagnostic methodseffective diagnostic methods exists. Recently, the emerging body of evidence regarding exosomes has rendered them potentially key players in the neuropsychiatric disease theragnostic. This study's aim was to investigate serumexosome proteomic expression in CSVD patients with depressive symptoms and to screen and analyze potential biomarkers for clinical diagnosis...
