Background: The mossy fiber sprouting (MFS) in the dentate gyrus is a common pathological change of epilepsy. Previous studies suggested that it is associated with drug-resistant epilepsy, and mossy cells control spontaneous seizures and spatial memory. Methods: We investigated the correlations among cognitive impairment, MFS, seizure frequency and drug resistance in a rat model of epilepsy induced by lithium–pilo Read More

Aim and Purpose: Progressive Stroke (PS) lacks effective treatment measures and leads to serious disability or death. Retinol binding protein 4 (RBP4) could be closely associated with acute ischemic stroke (AIS). We aimed to explore plasma RBP4 as a biomarker for detecting the progression in patients with AIS. Methods: Participants of this retrospective study were 234 patients with AIS within the 48 h onset of dise Read More

Introduction: This study aimed to investigate the clinical value of bispectral index (BIS) monitoring in assessing the consciousness and prognosis of Acute Cerebral Infarction (ACI) patients. Methods: In total, 64 patients who suffered from ACI with consciousness disturbance were enrolled in this study. Glasgow Coma Scale (GCS) was performed to evaluate the consciousness level of ACI patients, and BIS was used to monitor the d Read More

Background: Extracellular Vesicle (EV)-based therapy has been identified as a leading alternative approach in several disease models. EV derived from the Olfactory Ensheathing Cell (OEC) has been documented for its strong neuro-regenerative capacity. However, no information on its cargo that may contribute to its therapeutic effect has been available. Objective: To report the first miRNA profile of human OEC (hOEC) -EV, a Read More

Background: Stroke is one of the leading causes of death and disability in adulthood worldwide. A simple and convenient diagnostic method is needed for monitoring high-risk patients for stroke. Few POCTs are available for stroke diagnosis. Soluble blood P-selectin is known as a biomarker for platelet aggregation. Increased expression of P-selectin is observed in coronary artery disease, acute myocardial infarction, stroke a Read More

Objective: Angiogenesis led by brain microvascular endothelial cells (BMECs) contributes to the remission of brain injury after brain ischemia reperfusion. In this study, we investigated the effects of hydroxysafflor yellow A(HSYA) on angiogenesis of BMECs injured by OGD/R via SIRT1-HIF-1α-VEGFA signaling pathway. Methods: The OGD/R model of BMECs was established in vitro by OGD for 2h and reoxygenation for 24h. At Read More

Background: We investigated the combined effect of white blood cell (WBC) and platelet count on in-hospital mortality and pneumonia in acute ischemic stroke (AIS) patients. Methods: A total of 3,265 AIS patients enrolled from December 2013 to May 2014 across 22 hospitals in Suzhou city were included in the present study. We divided patients into four groups according to their level of WBC and platelet count: LWHP (low W Read More

Objective: The objective of this study is to determine whether the administration of intravenous alteplase would be beneficial or futile to patients with acute ischemic stroke caused by large vessel occlusion (LVO) before endovascular treatment (EVT) and determine the relationship between Hounsfield units (HU) in non-contrast computed tomography (NCCT) and recanalization by alteplase. Methods: We performed a retrospe Read More

Objective: Insulin resistance (IR) is a key pathological process during the development of cerebral small vessel disease (CSVD) and vascular cognitive impairment (VCI). The triglyceride- glucose index (TyG index) is considered a novel marker of insulin resistance and can represent peripheral tissue insulin sensitivity. Interleukin-34 (IL-34) is a cytokine of the short-chain helical hematopoietic cytokine family and recent Read More

Aim: This study investigated the protective effect of dimethyl fumarate (DMF) in rats by mediating glycogen synthase kinase 3β (GSK-3β)/Nrf2 using the middle cerebral artery embolization reperfusion (MCAO/R) rat model. Background: After an acute ischemic stroke (AIS), oxidative stress occurs. Dimethyl fumarate (DMF), a nuclear factor-E2-related factor 2 (Nrf2) activator, approved by the US Food and Drug Administration (FDA), Read More

Objective: Previous studies revealed that 18F-FDOPA uptake was significantly decreased in the subregions of striatum contralateral to the side with predominant symptoms and was helpful for improving the early diagnostic accuracy of PD. However, in these studies, more than half of the PD patients already have bilateral motor symptoms (mH stage≥2). This study was aimed to extend previous findings to a milder disease sta Read More
