Background: Hospital-acquired multidrug-resistant (MDR) bacterial meningitis and/or ventriculitis (MEN) is a severe condition associated with high mortality. The risk factors related to in-hospital mortality of patients with MDR bacterial MEN are unknown. We aimed to examine factors related to in-hospital mortality and evaluate their prognostic value in patients with MDR bacterial MEN treated in the neurointensive care unit.

Pre-treatment of rapamycin transformed M2 microglia alleviates traumatic cervical spinal cord injury via AIM2 signaling pathway in vitro and in vivo.

Background: Traumatic spinal cord injury (SCI) is still devastating. It was suggested that the inhibition of mTOR may alleviate neuronal inflammatory injury but its underlying mechanism remained to be elucidated. AIM2 (absent in melanoma 2) recruits ASC (apoptosis-associated speck-like protein containing a CARD) and caspase-1 to form the AIM2 inflammasome, activate caspase-1, and elicit inflammatory responses.

Surgical outcomes of basilar invagination type B without atlantoaxial dislocation through simple posterior fossa decompression: a retrospective study of 18 cases.

Background: Basilar invagination (BI) is a common disease in the craniocervical junction (CVJ) area. Posterior fossa decompression with/without fixation is a controversial surgical strategy for BI type B. This study aimed to evaluate the efficacy of simple posterior fossa decompression in treating BI type B.

Characteristics and therapeutic profile of TBI patients who underwent bilateral decompressive craniectomy: experience with 151 cases.

Background: Decompressive craniectomy (DC) and intracranial pressure (ICP) monitoring are common approaches to reduce the death rate of Traumatic brain injury (TBI) patients, but the outcomes of these patients are unfavorable, particularly those who receive bilateral DC. The authors discuss their experience using ICP and other potential methods to improve the outcomes of TBI patients who receive bilateral DC.

Methods: Data from TBI patients receiving bilateral DC from Jan.

Blood Pressure Variability Associates with Six-Month Outcomes in Acute Cervical Spinal Cord Injury: An Analysis of 105 Patients.

Objective: Blood pressure variability (BPV) has been shown to correlate with poor outcomes in patients with intracerebral hemorrhage (ICH) and traumatic brain injury. However, this association has not been elucidated in patients with traumatic cervical spinal cord injury (cSCI). We hypothesized that 24-hour BPV from time of admission is associated with worse outcomes in patients with cSCI.

p53 Inhibition Protects against Neuronal Ischemia/Reperfusion Injury by the p53/PRAS40/mTOR Pathway.

The underlying mechanisms of cerebral ischemia/reperfusion (I/R) injury are unclear. Within this study, we aimed to explore whether p53 inhibition exerts protective effects via the p53/PRAS40/mTOR pathway after stroke and its potential mechanism. Both an in vitro oxygen-glucose deprivation (OGD) model with a primary neuronal culture and in vivo stroke models (dMCAO or MCAO) were used.

Contribution of factor VII polymorphisms to coagulopathy in patients with isolated traumatic brain injury.

Background: Coagulopathy is a severe complication of traumatic brain injury (TBI) and can cause secondary injuries and death. Decrease of FVII activity contributes to the coagulopathy and progressive hemorrhagic injury (PHI) in patients with isolated TBI. Some polymorphic loci of coagulation factor VII (FVII) are shown to be essential for FVII activity.

Hypoxia-Induced Glioma-Derived Exosomal miRNA-199a-3p Promotes Ischemic Injury of Peritumoral Neurons by Inhibiting the mTOR Pathway.

The underlying molecular mechanisms that the hypoxic microenvironment could aggravate neuronal injury are still not clear. In this study, we hypothesized that the exosomes, exosomal miRNAs, and the mTOR signaling pathway might be involved in hypoxic peritumoral neuronal injury in glioma. Multimodal radiological images, HE, and HIF-1 staining of high-grade glioma (HGG) samples revealed that the peritumoral hypoxic area overlapped with the cytotoxic edema region and directly contacted with normal neurons.

Expression of TNF‑α and IL‑β can be suppressed via the PPAR‑γ/mTOR signaling pathway in BV‑2 microglia: A potential anti‑inflammation mechanism.

Currently, microglia are considered as crucial factors in suppressing inflammatory reactions, but the specific molecular mechanism remains unknown. To elucidate whether peroxisome proliferator‑activated receptor‑γ (PPAR‑γ) can inhibit neuroinflammatory cytokine expression via the mTOR signal pathway, the BV‑2 cell line was incubated with lipopolysaccharide (10 mM/ml) to induce an inflammatory injury. PPAR‑γ was activated by rosiglitazone, and was inhibited by GW9662.

Circulating neutrophil-to-lymphocyte ratio at admission predicts the long-term outcome in acute traumatic cervical spinal cord injury patients.

Background: The prognostic value of Neutrophil-to-Lymphocyte Ratio (NLR) for the outcome of acute cervical traumatic spinal cord injury (tSCI) patients has rarely been studied by now throughout the world.

Methods: We performed a single-center retrospective cohort study to evaluate the prognostic value of NLR from peripheral whole blood count in patients with acute cervical tSCI. Patients within 6 h of acute cervical tSCI treated between Dec 2008 and May 2018 in Huashan Hospital of Fudan University were enrolled.

Selection of Patients' Recumbent Position Laterality According to Physician Handedness Bias Increases the Success Rate of Lumbar Puncture: A Multicenter Study.

Background: Lumbar puncture (LP) is a medical procedure required during spinal anesthesia and for obtaining cerebrospinal fluid samples in the diagnosis of neurological disorders. The aim of this study was to assess the effects of physicians' handedness bias and the laterality of patients' recumbent position on the success rate of LPs.

Methods And Patients: A prospective multicenter study including 36 physicians (18 left-handed and 18 right-handed) and 7200 patients was conducted in 6 medical centers.

Effects of preadmission beta-blockers on neurogenic stunned myocardium after aneurysmal subarachnoid hemorrhage: A meta- analysis.

Objective: Spontaneous subarachnoid hemorrhage is mostly caused by the rupture of an aneurysm. Neurogenic stunned myocardium (NSM) is one of the most frequent complications caused by aneurysmal subarachnoid hemorrhage (aSAH). The possible pathogenesis of NSM may be that the catecholamine peak resulting from aSAH leads to subendocardial ischemia or coronary artery spasm.

Deep sequencing of the transcriptome reveals distinct flavonoid metabolism features of black tartary buckwheat (Fagopyrum tataricum Garetn.).

Black tartary buckwheat is recognized as 'black pearl' because of containg more rutin and other flavonoids as compared to yellow tartary buckwheat (traditional tartary buckwheat). Here, we show a genome-wide comparison of their transcriptomes by using an RNA-seq approach to elucidate the different molecular metabolism on the flowers from Black tartary buckwheat (HEIFENG No1) and yellow tartary buckwheat (XIQIAO No2). Over 48.
