Altitude-related features and prognosis in patients with reversible splenial lesion syndrome.

Introduction: RESLES (Reversible splenial lesion syndrome) can be observed secondary to various diseases, and intramyelinic edema may play a crucial role in the pathogenesis of SCC (Splenium of the corpus callosum). Some studies have suggested that hypoxic-ischaemic encephalopathy may constitute a risk factor for SCC lesions. However, the potential impact of high-altitude environments on SCC, especially during chronic exposure, remain obscure.

The treatment of high concentration wastewater in the natural gas processing industry.

The operation of the Cansolv tail gas treatment device in natural gas plants generates acidic and alkaline wastewater from the venturi unit and amine purification unit (APU), respectively. The APU wastewater is complex in composition and contains hard-to-degrade organic matter, which can adversely impact the normal functioning of the water treatment system. This study assesses the efficacy of three ozone-based advanced oxidation processes (ozone (O), ozone/hydrogen peroxide (O/HO), and ozone/Fenton (O/Fenton)) for treating Cansolv wastewater, with chemical oxygen demand (COD) and total organic carbon (TOC) serving as indicators of organic degradation.

A Comparison of Safety and Effectiveness Between Wingspan and Neuroform Stents in Patients With Middle Cerebral Artery Stenosis.

Percutaneous transluminal angioplasty and stenting with the Wingspan stent has proven safe and effective in patients with middle cerebral artery stenosis (MCAS), but the off-label use of the Neuroform stent might be an alternative treatment. This study aimed to compare the safety and effectiveness of the above two intracranial stents in patients with MCAS. We retrospectively analyzed consecutive patients with symptomatic MCAS who had been treated with the Neuroform EZ or the Wingspan stent.

Angioplasty and stenting for severe symptomatic atherosclerotic stenosis of intracranial vertebrobasilar artery.

This retrospective study is to investigate the safety and efficacy of the stent implanting for treating severe symptomatic atherosclerotic stenosis of the intracranial vertebrobasilar artery (ICVBA). 213 patients who had undergone intervention for severe symptomatic ICVBA stenosis between September 2012 to May 2018 were enrolled into this study. Among the 213 enrolled patients, 210 patients (98.

Wall enhancement ratio determined by vessel wall MRI associated with symptomatic intracranial aneurysms.

Purpose: To study the association of the enhancement ratio (ER) of aneurysmal wall enhancement (AWE) with symptomatic intracranial aneurysms (IAs), we hypothesized that the ER of AWE would be stronger in symptomatic IAs than in asymptomatic IAs, as assessed by high-resolution magnetic resonance imaging (HRMRI).

Materials And Methods: Between February 2016 and February 2018, 80 consecutive patients with 89 unruptured IAs were reviewed. Patients and IAs were divided into symptomatic and asymptomatic groups.

Clinical significances and features of prompt brain CT scan after intracranial artery stenting: analysis of 501 cases.

Cerebral hemorrhage is a serious complication of intracranial artery stenting that could be fatal without timely identification and treatment. Prompt brain CT scan would help to evaluate whether cerebral hemorrhage occurs, however, the diverse features of the CT scan immediately after stenting could influence the judgement sometimes. Therefore, we analyzed and summarized these features to help to determine the clinical significance of these CT features.

Wall enhancement ratio and partial wall enhancement on MRI associated with the rupture of intracranial aneurysms.

Objectives: To evaluate the risk factors for rupture of intracranial aneurysms (IAs) using high resolution MRI (HRMRI).

Methods: 91 consecutive patients with 106 IAs were reviewed from February 2016 to April 2017. Patients and IAs were divided into ruptured and unruptured groups.

Safety and Efficacy of Wingspan Stenting for Severe Symptomatic Atherosclerotic Stenosis of the Middle Cerebral Artery: Analysis of 278 Continuous Cases.

Objective: Our objective is to investigate the safety and long-term efficacy of the Wingspan stent (Boston Scientific, Natick, MA, USA) for treating severe atherosclerotic stenosis of the middle cerebral artery (MCA).

Methods: A total of 278 consecutive patients from our stroke database with clinical symptoms within the prior 90 days and intracranial atherosclerotic stenosis of 70% or above of the MCA were enrolled in this study between September 2012 and November 2014, and these patients were followed until the end of June 2015. The endpoint events included any stroke or death within 30 days after stenting and any subsequent ipsilateral ischemic stroke.

Association of CYP2C19 Polymorphisms with the Clinical Efficacy of Clopidogrel Therapy in Patients Undergoing Carotid Artery Stenting in Asia.

The CYP2C19 gene plays a detrimental role in the metabolism of clopidogrel. This study aimed to investigate the association between CYP2C19 polymorphisms and the clinical efficacy of clopidogrel therapy in patients who have undergone carotid artery stenting (CAS). CYP2C19 genotype screening was performed on 959 ischemic stroke patients.

Effects of ultrasound-combined microbubbles on hippocampal AchE fibers in rats.

Objective: To investigate the protective effect of ultrasound-combined microbubbles on hippocampal acetylcholinesterase (AchE) fibers in rats.

Methods: According to random digits table, 60 SD rats were divided into two groups, marrow stromal cells (MSCs) intracranial transplantation group and MSCs intracranial transplantation + ultrasonic microbubbles group. Marrow stromal cells were cultivated and isolated in vitro; 12 weeks after transplantation, spatial learning and memorizing abilities of rats were assessed by Morris water maze; AchE staining method was used to observe changes in density and appearance of AchE staining positive fibers in hippocampal CA1 region.

Serum 25-hydroxyvitamin D levels in Chinese children with autism spectrum disorders.

In recent years, increasing evidence has shown that children with autism spectrum disorders (ASDs) have lower levels of 25-hydroxyvitamin D [25(OH) D] relative to healthy controls. The purpose of this study was to evaluate the serum 25(OH) D levels in Chinese children with ASD. From January 2012 to December 2012, consecutive patients with ASD admitted to the Department of Neurology were identified.

[Triplex-forming oligonucleotide inhibits the expression of tissue factor gene in endothelial cells induced by the blood flow shear stress in rats].

Aim: To study the effect of antiparallel phosphorothioate triplex-forming oligonucleotide (apsTFO) matching with the shear stress response element (SSRE) of tissue factor (TF) gene promoter region on the expression of TF in endothelial cells (ECs) of rat common carotid artery stenosis.
