Objectives: Vasa vasorum is associated with the pathogenesis of various cerebrovascular diseases, but its presence in intracranial aneurysms (IA) and its ability to act as a predicting factor of IA rupture remain unrevealed.

Methods: Histological investigation was performed for 3 middle meningeal arteries and 25 human IAs that were sequentially collected from 2017 to 2019. Relevant medical information was collected from the hospital information and imaging system.

Background And Purpose: Brainstem hemorrhage (BSH) is the most devastating subtype of intracerebral hemorrhage (ICH) with the highest mortality ranging from 56 % to 61.2 %. However, there is no effective medical or surgical therapy to improve its outcomes in clinic to date due to lack of understanding of its injury mechanisms.

Background: Ventriculoperitoneal shunt (VPS) surgery remains the most widely accepted and used option method to treat post-hemorrhagic hydrocephalus (PHH) worldwide while lumboperitoneal shunt (LPS) serves as an effectively alternative treatment. However, the outcomes of VPS and LPS in the treatment of PHH have not been compared in a prospective trial.

Methods And Design: In this monocentric, assessor-blinded, non-randomized controlled trial, 75 eligible patients with PHH for each group will be recruited to compare the outcomes of VPS cohort with that of LPS cohort.

Objective: Published studies have shown hyperglycemia is associated with poor outcome in patients with intracerebral hemorrhage (ICH). However, the association between blood glucose and outcome in surgical ICH patients is unknown. In the present study, we sought to evaluate the predictive value of admission and postoperative glucose for 30-day outcome in patients with ICH undergoing neurosurgical treatment.

Skin wound caused by trauma, inflammation, surgery, or burns remains a great challenge worldwide since there is no effective therapy available to improve its clinical outcomes. Herein, we report a copper sulfide nanoparticles-incorporated hyaluronic acid (CuS/HA) injectable hydrogel with enhanced angiogenesis to promote wound healing. The prepared hydrogel could not only be injected to the wound site but also exhibited good photothermal effect, with temperature increasing to 50°C from room temperature after 10 min of near-infrared light irradiation.

Context: A well-established cell line of hemangioblastomas (HBs) is still lacking.

Aim: This study aims to explore a stable way to establish primary cell lines of HB stromal cells and investigate the morphological and molecular features of these cells.

Patients And Methods: Specimens of HBs from 13 patients were collected for establishment of primary cell lines of stromal cells.

While deferoxamine (DFO) has long been used as an FDA-approved iron chelator, its proangiogenesis ability attracts increasing number of research interests. To address its drawbacks such as short plasma half-life and toxicity, polymeric conjugated strategy has been proposed and shown superiority. Owing to intravenous injection and application in blood-related conditions, however, the blood interactions and antioxidation of the DFO-conjugates and the mechanisms underlying these outcomes remain to be elucidated.

Background: Intracranial aneurysm (IA) is a debilitating cerebrovascular degeneration. Current clinical diagnosis relies mainly on conventional angiogram except for some peculiar aneurysms. Nonetheless, there is no documentation of aneurysm showing robust intracranial artifact on computed tomography or magnetic resonance imaging.

Background: Aneurysmal subarachnoid hemorrhage (SAH) is a severe cerebrovascular disease. Rebleeding is an independent predictor of unfavorable outcome after aneurysmal SAH. However, the accuracy of aneurysm size for predicting rebleeding after aneurysmal SAH is still unclear.

The surgical suture has long been used to reconnect the injured tissues to restore their structure and function. However, its utility remains challenging in many areas, such as surgical site infections and minimally invasive surgeries. Herein, we report a novel surgical suture that possesses both antibacterial activity and shape memory effect to address these issues.

Toxicity to central nervous system tissues is the common side effects for radiotherapy of brain tumor. The radiation toxicity has been thought to be related to the damage of cerebral endothelium. However, because of lacking a suitable high-resolution vivo model, cellular response of cerebral capillaries to radiation remained unclear.

To detect the suitability of kiwifruit bacterial canker in Sichuan, a MaxEnt model based on distribution information and environmental variables was used to predict its potential distribution area and to analyze the impact of major environmental variables. The receiver operating characteristic curve was used to evaluate the accuracy of the model simulation. The average area under curve of 10 replicates was 0.

Objective: Seizures are common complications following intracranial aneurysms and present a greater risk to pediatric patients than adults. Though the risk factors of seizures in adults with intracranial aneurysms have been well documented, the risk factors in pediatric patients remain unknown. The aim of this study was to evaluate the risk factors for preoperative seizures and the effect of the treatment approach on postoperative seizures in pediatric patients with intracranial aneurysms.

Background: It has been acknowledged that delayed cerebral ischemia (DCI) can be diagnosed by computed tomography perfusion (CTP) when it occurs following aneurysmal subarachnoid hemorrhage (aSAH); however, the clinical role of CTP in the prediction of DCI remains unclear. We performed a meta-analysis to investigate the role of CTP in the identification of patients at risk for DCI during the acute phase (<4 days) after aSAH.

Materials And Methods: Relevant articles were systematically searched for analysis on PubMed, EMBASE, and Cochrane databases.

Objective: To evaluate whether the postoperative neutrophil-to-lymphocyte ratio (NLR) is a prognostic marker for patients with intracerebral hemorrhage (ICH) undergoing surgical hematoma evacuation.

Methods: This retrospective cohort study was conducted to identify patients with ICH who underwent hematoma evacuation between January 2013 and December 2018. Data on demographics, clinical features, laboratory tests (admission and postoperative), and imaging information were collected.

Previous studies indicated that both inflammatory responses and hyperglycemia are involved in the similar pathophysiological mechanisms after onset of intracerebral hemorrhage (ICH). However the relationship between hyperglycemia and inflammation remains unknown. We aim to evaluate the associations of hyperglycemia with inflammation and neutrophil to lymphocyte ratio (NLR) in patients with ICH.
