Materials And Methods: We retrospectively reviewed 40 patients who met the criteria from October 2019 to April 2021.

Direct carotid artery puncture for acute ischemic stroke: Local experience and systematic review.

Background: To establish surgical access during endovascular treatment of ischemic stroke, femoral artery puncture is most commonly performed followed by a small number of radial artery access procedures. However, there are few reports of carotid artery puncture.

Methods: We report the case of an 87-year-old woman who was admitted to hospital with hemiplegia of the left limb and loss of consciousness for 40 min, accompanied by urinary incontinence.

Cerebral Vasospasm-Left Heart Failure-Cerebral Infarction May Be a Potential Pathophysiological Mechanism of Malignant Cerebral Vasospasm.

Cerebral vasospasm (CV) and delayed cerebral ischemia are serious complications after ruptured aneurysm with high mortality and disability rate. However, there are few reports of cardiogenic CV, the mechanism is unclear, and the treatment recommended by the guidelines is not detailed. This article describes in detail a 47-year-old woman with intracranial aneurysm rupture and hemorrhage.

Mechanical Embolectomy for Superior Cerebellar Artery Embolism.

Acute embolism of the superior cerebellar artery is rarely reported. The treatment is mainly medication, decompressive craniectomy is performed when necessary, and mechanical thrombus removal is not recommended. This article describes the admission of a 69-year-old man with acute superior cerebellar artery embolization.

Glioma stem cell-derived exosomal miR-944 reduces glioma growth and angiogenesis by inhibiting AKT/ERK signaling.

In this study, we investigated the regulatory role of exosomal microRNA-944 (miR-944) derived from glioma stem cells (GSCs) in glioma progression and angiogenesis. Bioinformatics analysis showed that miR-944 levels were significantly lower in high-grade gliomas (HGGs) than low-grade gliomas in the Chinese Glioma Genome Atlas and The Cancer Genome Atlas datasets. The overall survival rates were significantly shorter for glioma patients expressing low miR-944 levels than high miR-944 levels.

Management of Elevated Blood Pressure After Stroke Thrombectomy for Anterior Circulation.

Thrombectomy is superior to intravenous thrombolysis for patients with large vessel occlusion in acute ischemic stroke, but nearly half of the patients still experience poor functional outcomes. Elevated blood pressure (BP) is widely observed in acute ischemic stroke, and BP may be one of the modifiable parameters that can potentially influence the outcomes; however, only observational studies exist to support current guidelines, and the recommended range for BP after thrombectomy is too wide to meet the clinical requirement. Randomized controlled trials are therefore needed to better understand the relationship between BP and outcomes after thrombectomy.

Silencing of PRDM5 increases cell proliferation and inhibits cell apoptosis in glioma.

Aim: PR-domain-containing 5 (PRDM5), a family member of PR-domain-containing zinc finger genes, has been reported to participate in modulate cellular processes, including cell growth, differentiation and apoptosis. It has also been found to function as a putative tumor suppressor in different types of cancer. The present study is the first, to the best of our knowledge, to report on the clinical significance of the expression of PRDM5 in glioma cell line.

Cutaneous Metastases of the Glioma.

Low grade glioma (LGG) is a very common primary brain neoplasm with a very good prognosis and the median survival of patients is approximately 8 years. With the development of current treatments such as surgery resection, radiotherapy, and chemotherapy, the recurrence rate and the distant metastasis rate of LGGs are largely decreased. Extracranial metastases are seldom happened.

Suppression of the Smurf1 Expression Inhibits Tumor Progression in Gliomas.

Glioblastoma, one of the common malignant brain tumors, results in the highly death, but its underlying molecular mechanisms remain unclear. Smurf1, a member of Nedd4 family of HECT-type ligases, has been reported to contribute to tumorigenicity through several important biological pathways. Recently, it was also found to participate in modulate cellular processes, including morphogenesis, autophagy, growth, and cell migration.

Overexpression of interleukin-33 is associated with poor prognosis of patients with glioma.

Interleukin-33 (IL-33) has shown diagnostic and prognostic values in multiple human cancers. However, there is little knowledge on the role of IL-33 in human gliomas and its association with disease prognosis. This study aimed to evaluate the value of IL-33 in the prognosis of glioma patients.

Background: The purpose of this study was to evaluate the visual outcome after extended endoscopic endonasal transsphenoidal surgery in patients with tuberculum sellae meningiomas (TSM).

Methods: A retrospective analysis was performed for 12 patients (4 men and 8 women) with TSMs who underwent extended endonasal transsphenoidal surgery with pure endoscopy between 2003 and 2008. Neuro-ophthalmic evaluation was performed preoperatively and postoperatively.

The expression of NF-E2-related factor 2 in the rat brain after traumatic brain injury.

Background: Secondary brain damage plays a critical role in the outcome of patients with traumatic brain injury (TBI). The mechanisms underlying secondary brain damage are complex. A target that can interrupt multiple mechanisms underlying secondary brain damage may represent a promising new therapeutic approach for TBI.

Role of Nrf2 in protection against traumatic brain injury in mice.

Previous studies have shown that nuclear factor erythroid 2-related factor 2 (Nrf2) plays a unique role in many physiological stress processes. The present study investigated the role of Nrf2 in modulating traumatic brain injury (TBI)-induced secondary brain injury. Wild-type Nrf2 (+/+) and Nrf2 (-/-)-deficient mice were subjected to a moderately severe weight-drop impact head injury.

Expression of vascular endothelial growth factor in human meningiomas and peritumoral brain areas.

Vascular endothelial growth factor (VEGF) is a regulator of angiogenesis, vasculogenesis, and vascular permeability. Recent reports suggest that VEGF may play a critical role in formation of peritumoral brain edema (PTBE) associated with meningiomas. While VEGF expression has been shown in meningiomas, studies have not focused on VEGF in the adjacent peritumoral brain regions.

Progesterone prevents traumatic brain injury-induced intestinal nuclear factor kappa B activation and proinflammatory cytokines expression in male rats.

We have previously shown that traumatic brain injury (TBI) can induce an upregulation of nuclear factor kappa B (NF-kappaB) and proinflammatory cytokines in the gut, which play an important role in the pathogenesis of acute gut mucosal injury mediated by inflammation. In this work, we investigated whether progesterone administration modulated intestinal NF-kappaB activity and proinflammatory cytokines expression after TBI in male rats. As a result, we found that administration of progesterone following TBI could decrease NF-kappaB binding activity, NF-kappaB p65 protein expression, and concentrations of interleukin-1beta (IL-1beta), and tumor necrosis factor-alpha (TNF-alpha) in the gut.

Expression of Toll-like receptor 4 in the basilar artery after experimental subarachnoid hemorrhage in rabbits: a preliminary study.

Inflammation and immunity play a crucial role in the pathogenesis of cerebral vasospasm after subarachnoid hemorrhage (SAH). Recently, a growing body of evidence indicates that Toll-like receptor (TLR) 4 is vital for inflammation and immunity. Therefore, this study aimed to detect the expression of TLR4 in the basilar artery in a rabbit SAH model and to clarify the potential role of TLR4 in cerebral vasospasm.
