Clinical Features and Risk Factors of Mortality in Patients with Posterior Reversible Encephalopathy Syndrome.

Objective: Although the prognosis of posterior reversible encephalopathy syndrome (PRES) is usually favourable and most patients wholly recover, the disorder can result in death in some patients. To date, the data on clinical features and risk factors for death are still lacking; therefore, we aim to investigate the clinical features and long-term prognostic risk factors of PRES in the present study.

Methods: The patients with PRES were identified from the First Affiliated Hospital of Zhengzhou University from June 2011 to June 2020.

MicroRNA-132 attenuates LPS-induced inflammatory injury by targeting TRAF6 in neuronal cell line HT-22.

Epilepsy is a common neurological disorder in the central nervous system. Inflammation disrupts the blood-brain barrier (BBB), which is responsible for maintaining brain homeostasis. This study was aimed to investigate the functional role of microRNA (miR)-132 in hippocampal HT-22 cells under lipopolysaccharide (LPS) stimulation.

Preliminary study on pathogenesis of bronchial asthma in children.

Background: The etiology and pathogenesis of bronchial asthma remain unclear. This study is to investigate the risk factors related to bronchial asthma onset in children from genetics and immunology and preliminarily reveal the pathogenesis of bronchial asthma in children.

Methods: Real-time quantitative PCR was adopted to detect the expression level of TRPV1 gene and mRNA and enzyme-linked immunosorbent assay method to the total immunoglobulin E level and levels of IL-4, IL-5, and IFN-γ in serum in peripheral venous blood for children in two groups.

Catalpol provides protective effects against cerebral ischaemia/reperfusion injury in gerbils.

Objectives: To investigate the protective effect of catalpol on cerebral ischaemia/reperfusion (CI/R) injury in gerbils and further explore the underlying mechanism.

Methods: A gerbil model of CI/R was prepared by bilateral common carotid occlusion for 10 min followed by 6 h reperfusion. Catalpol (5, 10 or 20 mg/kg per day) was injected intraperitoneally for 3 days before the carotid occlusion.

Effects of resveratrol on apoptosis in a rat model of vascular dementia.

Resveratrol is a natural polyphenol widely present in plants, particularly in the skin of red grapes and in wine. It possesses a wide range of biological effects and exhibits neuroprotective effects in numerous diseases. However, data evaluating the effects of resveratrol in vascular dementia (VaD) are lacking.

Effects of catalpol on ATPase and amino acids in gerbils with cerebral ischemia/reperfusion injury.

This study aimed to investigate the effects of catalpol on ATPase and amino acids in gerbils following cerebral ischemia/reperfusion (CI/R) injury. Gerbil model of CI/R was prepared by bilateral common carotid occlusion for 10 min followed by 6 h of reperfusion. Catalpol (5, 10 or 20 mg/kg per day) was injected intraperitoneally for 3 days before the carotid occlusion.

Dendritic morphology of neurons in medial prefrontal cortex and hippocampus in 2VO rats.

Cerebral ischemia is the main cause of cognitive impairment. Changes in dendritic morphology and spines have been shown to occur with synaptic plasticity and cognitive function. Bilateral occlusion of the common carotid arteries (2VO) in rats was an effective model of chronic cerebral ischemia.

Wernicke's encephalopathy in a patient with acute pancreatitis: unusual cortical involvement and marvelous prognosis.

Wernicke's encephalopathy (WE) is a severe neurological disorder caused by thiamine deficiency. Clinically, it is most frequently observed in people with alcohol abuse. WE, however, can occur in any clinical condition associated with malnutrition or thiamine deficiency.

[Protective effect of musk extract on rat's cerebral cortical neurons with inflammatory injury].

Objective: To investigate the protective effects of musk extract (ME) and its possible mechanism on rat's cerebral cortical neurons with inflammatory injury induced by lipopolysaccharide (LPS).

Methods: Neurons and astrocytes from newborn rat cerebral cortex were cultured in vitro respectively, and the astrocyte conditioned medium (ACM), obtained by treating astrocytes with 10 mg/L LPS and different concentrations of ME for 24 h, was added in the culture fluid of neurons. The survival rate and apoptotic rate of neurons were measured by MTT method and AO/EB stain; and the changes of inflammatory factors in the ACM were determined by ELISA.

[Expression of microRNA in neonatal rats with hypoxic-ischemic brain damage].

Objective: To study the changes of microRNA expression in cortex tissues in neonatal rats with hypoxic-ischemic brain damage (HIBD)and the possible roles of microRNA in the pathogenesis of HIBD. METHODS Rat HIBD model was prepared. The cortex tissues were obtained 14 days after the HIBD event.

[Effects of DSCAM on differentiation of rat marrow mesenchymal stem cells into neurons in vitro].

Objective: To study the effects of Down syndrome cellular adhesion molecule (DSCAM) on differentiation of rat marrow mesenchymal stem cells (MSCs) into neurons in vitro.

Methods: MSCs from Sprague-Dawley rats were induced into neurons by baicalin. The expression of DSCAM before and after induction was evaluated by immunocytochemical staining and Western blot assay.

[Effects of Notch-1 signaling in bone marrow mesenchymal stem cells differentiating into neurons: experiment in vitro].

Objective: To investigate the role of Notch-1 signaling in bone marrow mesenchymal stem cells (MSCs) differentiating into neurons.

Methods: Mice Notch-1 small hairpin RNA (mNotch-1 shRNA) was constructed and transfected into the MSCs obtained from the tibiae of BALB/c mice. MSCs transfected with glyceraldehyde-3-phosphate hydoxygenase (GADPH) shRNA and untransfected MSCs were used as controls.
