Evaluating high-flow oxygen therapy after mechanical thrombectomy under general anesthesia in acute ischemic stroke: A retrospective single-center study.

Background: The use of mechanical thrombectomy for acute intracranial vascular occlusion under general anesthesia with endotracheal intubation is well-established as a safe and effective method. However, the process of extubation post-surgery presents challenges for certain patients. This retrospective study assesses the safety and efficacy of combining mechanical ventilation with high-flow oxygen inhalation as an interim strategy, while also examining its impact on long-term clinical outcomes.

Factors influencing the prognosis of acute basilar artery occlusion patients treated endovascularly: the impact of treatment time window and preoperative symptoms.

Objective: The aim of this study was to examine the factors influencing the prognosis of patients diagnosed with acute basilar artery occlusion (BAO) who receive endovascular treatment. Our particular emphasis was on the predictive implications of the time window for treatment (from symptom onset to femoral artery puncture) and preoperative symptoms for prognosis.

Methods: A retrospective analysis of data collected from 51 BAO patients who received endovascular treatment at the Neurosurgery Department of Jinhua Central Hospital from April 2018 to October 2021 was undertaken.

Methods: In this prospective observational study, serum RvD1 levels were measured in 123 patients with aSAH and in 123 healthy volunteers.

Progress in Stem Cell Therapy for Spinal Cord Injury.

Background: Spinal cord injury (SCI) is one of the serious neurological diseases that occur in young people with high morbidity and disability. However, there is still a lack of effective treatments for it. Stem cell (SC) treatment of SCI has gradually become a new research hotspot over the past decades.

Immunogenicity and protective efficacy of an EB66 cell culture-derived duck Tembusu virus vaccine.

The avian EB66 cell line, derived from duck embryonic stem cells, has been widely used for producing human and animal therapeutic proteins and vaccines. In current study we evaluated the potential use of EB66 cell line in a cell culture-derived duck Tembusu virus (DTMUV) vaccine development. After optimizing the growth conditions of DTMUV HB strain in EB66 cells, we successfully generated three batches of viruses with ELD titres of 10/0.

Retrospective analysis of brain abscess in 183 patients: A 10-year survey.

This study aims to identify predictive factors related to clinical outcome, reoperation, and complications in patients with brain abscess.Patients with a diagnosis of brain abscess at discharge at the Second Affiliated Hospital of Zhejiang University School of Medicine between 2008 and 2018 were reviewed. Logistic regression was used to identify predictive factors associated with Glasgow Outcome Scale (GOS) at discharge, GOS at 1 year after discharge, reoperation and complications.

The Neuroprotective Effects of Necrostatin-1 on Subarachnoid Hemorrhage in Rats Are Possibly Mediated by Preventing Blood-Brain Barrier Disruption and RIP3-Mediated Necroptosis.

Despite the substantial efforts to elucidate the role of early brain injury in subarachnoid hemorrhage (SAH), an effective pharmaceutical therapy for patients with SAH continues to be unavailable. This study aims to reveal the role of necroptosis after SAH, and explore whether the disruption of the blood-brain barrier (BBB) and RIP3-mediated necroptosis following SAH in a rat SAH model are altered by necrostatin-1 via its selective inhibition of receptor-interacting protein kinase 1 (RIP1). Sixty-five rats were used in the experiments.

Mesencephalic astrocyte-derived neurotrophic factor affords neuroprotection to early brain injury induced by subarachnoid hemorrhage via activating Akt-dependent prosurvival pathway and defending blood-brain barrier integrity.

This study aimed to explore the neuroprotective effect of mesencephalic astrocyte-derived neurotrophic factor (MANF) protein on early brain injury caused by subarachnoid hemorrhage (SAH) and the relevant mechanisms in experimental rats, expecting to understand whether MANF was a potential therapeutic target for SAH treatment. A perforation model of SAH was introduced into the study. Recombinant human MANF (rh-MANF) and protein kinase B (Akt) inhibitor (MK2206) were used to explore the effect and the mechanisms.

Neuroprotective Effects of Magnesium Lithospermate B against Subarachnoid Hemorrhage in Rats.

Subarachnoid hemorrhage (SAH) is a severe cerebrovascular disease with few effective pharmacotherapies available. Salvia miltiorrhiza, a traditional Chinese medicinal herb, has been widely used to treat cardiovascular diseases for centuries. Recent studies have demonstrated that magnesium lithospermate B (MLB), a bioactive ingredient extracted from Salvia miltiorrhiza, exerts neuroprotective effects in several central nervous system insults.

ErbB4 Preserves Blood-Brain Barrier Integrity via the YAP/PIK3CB Pathway After Subarachnoid Hemorrhage in Rats.

Studies have suggested that blood-brain barrier (BBB) disruption contributes to the pathogenesis of early brain injury after subarachnoid haemorrhage (SAH). Activation of the receptor tyrosine kinase ErbB4 can cause intramembrane proteolysis and release a soluble intracellular domain (ICD) that modulates transcription in the nucleus. This study was carried out to investigate the potential roles of ErbB4 in preserving BBB integrity after experimental SAH, as well as the underlying mechanisms of its protective effects.

Phosphodiesterase-4 inhibition confers a neuroprotective efficacy against early brain injury following experimental subarachnoid hemorrhage in rats by attenuating neuronal apoptosis through the SIRT1/Akt pathway.

Phosphodiesterase-4 (PDE4) plays a fundamental role in a range of central nervous system (CNS) insults, however, the role of PDE4 in early brain injury (EBI) after subarachnoid hemorrhage (SAH) remains unclear. The current study was designed to investigate the role of PDE4 in EBI after SAH and explore the potential mechanism. The SAH model in Sprague-Dawley rat was established by endovascular perforation process.

Rolipram Attenuates Early Brain Injury Following Experimental Subarachnoid Hemorrhage in Rats: Possibly via Regulating the SIRT1/NF-κB Pathway.

Early brain injury (EBI) is the primary cause of poor outcome in subarachnoid hemorrhage (SAH) patients. Rolipram, a specific phosphodiesterase-4 inhibitor which is traditionally used as an anti-depressant drug, has been recently proven to exert neuroprotective effects in several central nervous system insults. However, the role of rolipram in SAH remains uncertain.

Mdivi-1 ameliorates early brain injury after subarachnoid hemorrhage via the suppression of inflammation-related blood-brain barrier disruption and endoplasmic reticulum stress-based apoptosis.

Aberrant modulation of mitochondrial dynamic network, which shifts the balance of fusion and fission towards fission, is involved in brain damage of various neurodegenerative diseases including Parkinson's disease, Huntington's disease and Alzheimer's disease. A recent research has shown that the inhibition of mitochondrial fission alleviates early brain injury after experimental subarachnoid hemorrhage, however, the underlying molecular mechanisms have remained to be elucidated. This study was undertaken to characterize the effects of the inhibition of dynamin-related protein-1 (Drp1, a dominator of mitochondrial fission) on blood-brain barrier (BBB) disruption and neuronal apoptosis following SAH and the potential mechanisms.

Chicken IL-7 as a potent adjuvant enhances IBDV VP2 DNA vaccine immunogenicity and protective efficacy.

Our previous work has demonstrated that the mammalian interleukin-7 (IL-7) gene can enhance the immunogenicity of DNA vaccine. Whether chicken IL-7 (chIL-7) possesses the ability to enhance the immunogenicity of VP2 DNA vaccine of infectious bursal disease virus (IBDV) remained unknown. To investigate this, we constructed a VP2 antigenic region (VP2366) gene and chIL-7 gene vectors, co-immunized chicken with these vectors and analyzed the effects of the chIL-7 gene on VP2366 gene immunogenicity.

Efficacy Evaluation of an Inactivated Duck Tembusu Virus Vaccine.

To evaluate the potential use of an inactivated virus-based vaccine for the control and prevention of the newly emerged duck Tembusu virus infection in China, a duck Tembusu virus isolate, Tembusu-HB, was propagated in 12-day-old duck embryos and inactivated by treatment with formaldehyde. The inactivated viral antigen was emulsified with mineral oil, and five batches of the vaccine were manufactured. The immunogenicity and protection efficacy of the vaccine were evaluated in Beijing ducks and Beijing white geese.
