Background: Mechanical thrombectomy (MT) has become the mainstay of treatment for acute ischemic stroke (AIS) recently. This case-control study aimed to identify the pivotal role of inflammation in the prognosis of AIS patients after MT.

Methods: Altogether, 70 AIS patients who underwent MT were retrospectively recruited for this study.

Aims: This study aimed to unravel the dehydration status of patients with cerebral venous sinus thrombosis (CVST) to facilitate the understanding of dehydration in CVST.

Methods: This was a multicenter retrospective study and three populations were recruited, namely, patients with CVST, CVST mimics, and healthy subjects. Blood samples were obtained 1-2 days after admission to assess dehydration status.

Association between inflammatory biomarkers and venous thromboembolism: a systematic review and meta-analysis.

Background: Venous thromboembolism (VTE) is a common thrombotic vascular disease that has a significant impact on people's well-being and quality of life. A plethora of clinical studies explore the relationship between inflammatory biomarkers and VTE but yield conflicting results. This article proposed to pool these studies to draw a more convincing conclusion.

Neuroinflammation and anti-inflammatory therapy for ischemic stroke.

Stroke remains one of the most devastating and challenging neurological diseases worldwide. Inflammation, as well as oxidative stress is one of the main contributors to post-stroke injuries, and oxidative stress can further induce inflammation. Moreover, the inflammatory response is closely related to immune modulation in ischemic stroke progression.

LncRNA Expression Profiling of Ischemic Stroke During the Transition From the Acute to Subacute Stage.

Ischemic stroke induces profound effects on the peripheral immune system, which may participate the infectious complications. However, the exact function and mechanism of immune reaction in stroke development are not well-elucidated. Recently, several long non-coding RNAs (LncRNAs) are reported to affect ischemic stroke process, especially the immunological response after stroke.

Multiple intracranial arterial stenosis influences the long-term prognosis of symptomatic middle cerebral artery occlusion.

Background: Large intracranial occlusive vascular disease is a major contributor to the incidence of stroke worldwide, especially when it involves the middle cerebral artery (MCA). The data on the prognosis of symptomatic atherosclerotic MCA occlusions (MCAO) with concomitant intracranial arterial disease (MCAO-AIS) are limited. MCAO-AIS may reflect the extent of the atherosclerotic intracranial disease, we hypotheses that coexisting intracranial arterial disease influenced the prognosis of MCAO.

Chromosome 9p21.3 Variants Are Associated with Cerebral Infarction in Chinese Population.

Common variants of chromosome 9p21.3 associated with coronary disease have been established, but the association of 9p21.3 and cerebral infarction (CI) is not consistent.

Ranitidine reduced levodopa-induced dyskinesia in a rat model of Parkinson's disease.

Background: Chronic administration of levodopa in Parkinson's disease leads to debilitating involuntary movements, termed levodopa-induced dyskinesia (LID). The pathogenesis of LID is poorly understood. Previous research has shown that histamine H2 receptors are highly expressed in the input (striatum) and output (globus pallidus, substantia nigra) regions of the basal ganglia, particularly in the GABAergic striatopallidal and striatonigral pathways.

Intranasal administration of nerve growth factor ameliorate β-amyloid deposition after traumatic brain injury in rats.

The marked increase of amyloid-β (Aβ) peptide after traumatic brain injury (TBI), confers a risk factor for Alzheimer's disease (AD) in patients' later life. Nerve growth factor (NGF) is great potential to repair brain injury. But its clinical application is limited because of lacking feasible methods for delivering NGF into brain.

Association between plasma homocysteine levels and obstructive sleep apnoea in patients with ischaemic stroke.

We aimed to investigate the association between plasma homocysteine and obstructive sleep apnoea (OSA) syndrome in patients with ischaemic stroke. A total of 102 patients with ischaemic stroke were classified into four OSA groups based on their apnoea-hypopnoea index (AHI): absent (AHI < 5/hour); mild (5-14/hour); moderate (15-30/hour); and severe (> 30/hour). The mean (± standard deviation) homocysteine levels in the four OSA groups were: absent, 8.

Intranasal ginsenoside Rb1 targets the brain and ameliorates cerebral ischemia/reperfusion injury in rats.

Ginsenoside Rb1 (GRb1) has been shown to benefit many central nervous system (CNS) disorders, including stroke. However, its bioavailability is low after oral administration due to poor absorption. Intranasal administration has been considered as an effective method for central nervous system drug delivery for its brain-targeting effect.

Evaluation of angiographic changes of the anterior choroidal and posterior communicating arteries for predicting cerebrovascular lesions in adult moyamoya disease.

To ascertain the relationship between angiographic changes of the anterior choroidal and posterior communicating arteries (AChA-PComA) and cerebrovascular lesions in adult patients with moyamoya disease (MMD), we reviewed cerebral angiograms from 132 adult patients with MMD (68 with ischemia and 64 with hemorrhage). The angiographic findings of the AChA-PComA in each symptomatic hemisphere were graded on a scale of 0 to 3. The data were statistically analyzed for correlation with cerebrovascular lesions.

Decreased serum brain-derived neurotrophic factor (BDNF) is associated with post-stroke depression but not with BDNF gene Val66Met polymorphism.

Background: Decreased brain-derived neurotrophic factor (BDNF) has been demonstrated in animal models and patients with depression. However, little is known about changes in BDNF in post-stroke depression (PSD). This study investigated the changes in serum BDNF in patients with PSD, and evaluated whether serum concentrations of BDNF were associated with BDNF gene Val66Met polymorphism.

Hyperintense vessels on FLAIR: a useful non-invasive method for assessing intracerebral collaterals.

Objective: This study was aimed to evaluate relationship between hyperintense vessels (HV) on fluid-attenuated inversion recovery (FLAIR) and artery steno-occlusion related intracerebral collaterals.

Materials And Methods: A total of 233 patients with 260 atherosclerotic lesions in the M1 segment of the middle cerebral artery (MCA) were examined with FLAIR and digital subtraction angiography (DSA). HV were graded as 0, 1, 2 and 3 by its distributions in the MCA territory.

Influence of residual stenosis on clinical outcome and restenosis after middle cerebral artery stenting.

Background: The purpose of this study was to assess whether the residual stenosis has effect on restenosis after stenting for atherosclerotic stenosis in the middle cerebral artery.

Methods: Sixty-seven patients underwent 69 single-stent procedures successfully for atherosclerotic stenosis ≥70% in the M1 segment of middle cerebral artery were reviewed retrospectively. All patients were classified into two groups: nonresidual (≤30%) and residual (>30%) stenosis.

Influence of vessel size and tortuosity on in-stent restenosis after stent implantation in the vertebral artery ostium.

Purpose: Percutaneous transluminal angioplasty and stenting is emerging as an alternative for treating atherosclerotic stenosis in the vertebral artery ostium. However, in-stent restenosis (ISR) still remains a critical issue to be addressed. Little is known about the relationship between anatomic characteristics of the artery and ISR after stent implantation.

Comparison of BMSs with SES for symptomatic intracranial disease of the middle cerebral artery stenosis.

This study was designed to compare the clinical and angiographic outcomes of patients with symptomatic atherosclerotic middle cerebral artery stenosis treated with balloon-mounted stents (BMS) and self-expandable Wingspan system (SES). We reviewed the 69 consecutive stent placement procedures for symptomatic atherosclerotic stenosis (≥70) in M1 segment of middle cerebral artery in 67 patients in 3 years. According to the stent types, the patients were classed as BMS and SES groups.
