Early autoimmunity and outcome in virus encephalitis: a retrospective study based on tissue-based assay.

Unlabelled: To explore the autoimmune response and outcome in the central nervous system (CNS) at the onset of viral infection and correlation between autoantibodies and viruses.

Methods: A retrospective observational study was conducted in 121 patients (2016-2021) with a CNS viral infection confirmed via cerebrospinal fluid (CSF) next-generation sequencing (cohort A). Their clinical information was analysed and CSF samples were screened for autoantibodies against monkey cerebellum by tissue-based assay.

Serological biomarkers in autoimmune GFAP astrocytopathy.

Autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A) is a newly defined meningoencephalomyelitis. The pathogenesis of GFAP-A is not well understood. The present study measured the expression levels of 200 serological cytokines in GFAP-A patients, NMOSD patients and healthy controls (HCs).

Serum molecular biomarkers in neuromyelitis optica and multiple sclerosis.

Background: Neuromyelitis optica spectrum disorder (NMOSD) is a rare and severe inflammatory demyelinating disorder of the central nervous system (CNS), which mainly affects the optic nerves and spinal cord. The aims of this study were to determine whether the expression levels of serological cytokines could distinguish 1) NMOSD from healthy controls (HCs); and 2) NMOSD patients with and without the aquaporin-4 (AQP4) antibody biomarker from each other; and 3) NMOSD patients without the antibody to AQP4 from MS patients.

Methods: The expression levels of 200 proteins in serum from 41 NMOSD (32 with antibodies to AQP4, 9 without antibodies to AQP4), 12 MS patients, and 34 HCs were measured using glass-based antibody arrays.

Autoimmune glial fibrillary acidic protein astrocytopathy with lesions distributed predominantly in the entire spinal cord.

Autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy has been considered a novel central nervous system autoimmune disease characterized by relapse and responsiveness to corticosteroid with a specific GFAP-Immunoglobulin G (IgG) being noted in cerebrospinal fluid. We report the case of a 21-year-old girl presenting with dysuria and weariness, who subsequently developed blurry vision, slight dysphagia, slurred speech, and sensory abnormality. GFAP-IgG was detected in her cerebrospinal fluid.

The Effects of Statins on Infections after Stroke or Transient Ischemic Attack: A Meta-Analysis.

Background: Previous studies have reported that statins can prevent infections, and these findings were ascribed to the anti-inflammatory and immunomodulatory properties of statins. However, the effects of statins on the risk of infection after stroke or transient ischemic attack (TIA) remain controversial. The aim of this study was to evaluate the relationship between statins and the risk of infection after stroke or TIA by means of a meta-analysis.

Is serum total bilirubin useful to differentiate cardioembolic stroke from other stroke subtypes?

Background: Previous studies have reported that the total bilirubin (TB) level is associated with coronary artery disease, heart failure and atrial fibrillation. These heart diseases can produce cardiogenic cerebral embolism and cause cardioembolic stroke. However, whether the serum TB could be a biomarker to differentiate cardioembolic stroke from other stroke subtypes is unclear.

Relationship between neuromyelitis optica-IgG status and spinal cord magnetic resonance imaging in patients with neuromyelitis optica.

Background: Despite the large scale technical innovations that have been made, a number of patients with neuromyelitis optica (NMO) are lacking NMO-IgG in both serum and cerebrospinal fluid. Longitudinally extensive spinal cord (LESC) lesions and linear lesions are associated with NMO. However, differences of spinal cord magnetic resonance imaging (MRI) features, including LESC lesions and linear lesions, between NMO-IgG positive and negative patients still remain unknown.

Cell-permeable Tat-NBD peptide attenuates rat pancreatitis and acinus cell inflammation response.

Aim: To investigate the effects of Tat-NEMO-binding domain (NBD) peptide on taurocholate-induced pancreatitis and lipopolysaccharide (LPS)-stimulated AR42J acinus cells inflammatory response in rats.

Methods: Sodium taurocholate (5%) was used to induce the pancreatitis model. Forty-eight rats from the taurocholate group received an intravenous bolus of 13 mg/kg Tat-NBD (wild-type, WT) peptide, Tat-NBD (mutant-type, MT) peptide, NBD peptide or Tat peptide.

Nuclear factor kappa B: a marker of chemotherapy for human stage IV gastric carcinoma.

Aim: To detect the nuclear factor kappa B (NF-kappaB) condition in human stage IV gastric carcinoma patients and to explore the correlation between NF-kappaB activation and survival of these patients after chemotherapy.

Methods: Expression of NF-kappaB-p65 was determined by immunohistochemical analysis. Activity of NF-kappaB DNA-binding in carcinoma tissue was detected by electrophoretic mobility shift assay.

[Activation of nuclear factor-kappa B and its modulalorg effects on intercellular adhesion molecule-1 expression in mice with dextran sulphate sodium-induced rat colitis].

Objective: To investigate the changes in the activity of nuclear factor-kappaB (NF-kappa B) in mice with dextran sulphate sodium (DSS)-induced rat colitis and its modulalorg effect on intercellular adhesion molecule-1 (ICAM-1) expression.

Methods: Twenty normal male mice were randomized into DSS group and normal saline (NS) control group according to a matched-pair design. From days 1 to 7, the mice in DSS group were subjected to oral administration of 5%DSS solution, and from days 8 to 20, NS was given instead, for a total of 3 cycles.

Activation of nuclear factor-kappa B and effects of pyrrolidine dithiocarbamate on TNBS-induced rat colitis.

Aim: To explore the changes of nuclear factor-kappa B (NF-kappaB) DNA-binding activity, the expression of intercellular adhesion molecule-1 (ICAM-1) regulated by NF-kappaB at various times and to evaluate the effects of pyrrolidine dithiocarbamate (PDTC) on trinitrobenzene sulfonic acid (TNBS)-induced rat colitis.

Methods: TNBS of 0.6 mL was mixed with ethanol of 0.
