The expression profiles of circular RNAs and competing endogenous RNA networks in intrahepatic cholangiocarcinoma.

Intrahepatic cholangiocarcinoma (iCCA) is a heterogeneous entity with diverse etiologies, morphologies, and clinical outcomes, but our knowledge of its epidemiology and carcinogenesis is very limited. The expression patterns of circRNAs were explored in iCCA tissues and corresponding adjacent normal ones, denoted by (iCCA) and (iCCAP), respectively, using high-throughput sequencing. A total of 117 differential expressed (DE) circRNAs were identified.

Posterior reversible encephalopathy syndrome with a special focus on seizures.

Posterior reversible encephalopathy syndrome (PRES) is a neurological disorder characterized by headache, seizures, confusion and visual disturbances, as well as potentially reversible neuroimaging findings in most patients after proper treatment. Seizures is one of the most common clinical presentations of PRES. This review summarizes the potential pathophysiology and clinical features of PRES, as well as a multimodal approach to imaging and also briefly discusses the phenomenon of seizures in paediatric population.

Thioredoxin-Interacting Protein (TXNIP) Regulates Parkin/PINK1-mediated Mitophagy in Dopaminergic Neurons Under High-glucose Conditions: Implications for Molecular Links Between Parkinson's Disease and Diabetes.

Patients with diabetes mellitus have a higher risk of developing Parkinson's disease (PD). However, the molecular links between PD and diabetes remain unclear. In this study, we investigated the roles of thioredoxin-interacting protein (TXNIP) in Parkin/PINK1-mediated mitophagy in dopaminergic (DA) cells under high-glucose (HG) conditions.

X-ray induces mechanical and heat allodynia in mouse via TRPA1 and TRPV1 activation.

Radiotherapy-related pain is a common adverse reaction with a high incidence among cancer patients undergoing radiotherapy and remarkably reduces the quality of life. However, the mechanisms of ionizing radiation-induced pain are largely unknown. In this study, mice were treated with 20 Gy X-ray to establish ionizing radiation-induced pain model.

Case of Childhood Absence Epilepsy with Focal Spikes.

Background: Childhood absence epilepsy is a common generalized epilepsy syndrome characterized by childhood onset of frequent sporadic absence seizures. During onset, the electroencephalogram exhibits bilateral, symmetric, and synchronous discharges of approximately 3 Hz of generalized spike-and-wave complexes. Focal spikes are often found in children with focal epilepsy but are not common in absence epilepsy.

Mixed cerebrovascular disease in an elderly patient with mixed vascular risk factors: a case report.

Background: Mixed cerebrovascular disease is a diagnostic entity that presents with hemorrhagic and ischemic stroke clinically and/or subclinically. Here, we report a patient with mixed vascular risk factors, who presented with multiple intracerebral hemorrhages and a simultaneously occurring cerebral infarction with hemorrhagic transformation.

Case Presentation: A 63-year-old male with no history of trauma or prior neurological disease presented with a sudden onset of weakness in his right limbs, followed by an episode of focal seizure without impaired awareness.

Analysis of heart rate variability-related indexes in the interictal period in patients with focal epilepsy.

Aims: Changes in cardiac autonomic nervous function have been evaluated by studying the related indexes of heart rate variability (HRV) in patients with focal epilepsy (FE) in the interictal period.

Main Methods: A total of 30 FE patients who were treated in our department from July 2015 to May 2017, were included into this study. These patients were divided into three pairs of groups: less frequent seizure group and more frequent seizure group; medication group and non-medication group; <10 years disease group and ≥10 years disease group.

Thioredoxin-interacting protein induced α-synuclein accumulation via inhibition of autophagic flux: Implications for Parkinson's disease.

Aims: Thioredoxin-interacting protein (TXNIP) is associated with activation of oxidative stress through inhibition of thioredoxin (Trx). However, some evidences point out that TXNIP acts as a scaffolding protein in signaling complex independent of cellular redox regulation. The autophagy-lysosomal pathway plays important roles in the clearance of misfolded proteins and dysfunctional organelles.

Individualized rituximab treatment for relapsing neuromyelitis optica: a pediatric case report.

Background: Neuromyelitis optica is an autoimmune inflammatory disorder of the central nervous system. Current therapeutic approaches are based on small uncontrolled trials, case series, or case reports. There are only a few case reports describing rituximab for pediatric neuromyelitis optica.

Increased glucagon-like peptide-1 secretion may be involved in antidiabetic effects of ginsenosides.

Panax ginseng is one of the most popular herbal remedies. Ginsenosides, major bioactive constituents in P. ginseng, have shown good antidiabetic action, but the precise mechanism was not fully understood.

Insulin deficiency induces abnormal increase in intestinal disaccharidase activities and expression under diabetic states, evidences from in vivo and in vitro study.

Structural and functional alterations in the gastrointestinal tract of diabetic patients are often accompanied by increase in absorption of intestinal glucose and activities of brush-border disaccharidases. The purpose of this study was to investigate the role of insulin in regulating intestinal disaccharidases using in vivo and in vitro experiments. Streptozotocin-induced diabetic rats and normal rats received protamine zinc insulin (10 IU/kg) subcutaneously twice daily for 5 weeks.

Insulin suppresses the expression and function of breast cancer resistance protein in primary cultures of rat brain microvessel endothelial cells.

The aim of this study was to investigate the role of insulin in the regulation of breast cancer resistance protein (BCRP) function and expression using primary cultured rat brain microvessel endothelial cells (rBMECs) as an in vitro model of the blood brain barrier (BBB). The prazosin uptake assay and western blot analysis were used to assess the function and expression of BCRP, respectively. It was noted that the uptake of prazosin by rBMECs was time-, concentration- and temperature-dependent.

Verapamil exerts biphasic modulation on phenobarbital transport across the blood-brain barrier: evidence from an in vivo and in vitro study.

The aim of the study was to report a concentration-dependently biphasic effect of verapamil (VER) on the transport of phenobarbital (PB) across the blood-brain barrier (BBB) in vitro and in vivo. The uptake of PB by rat brain microvessel endothelial cells (rBMECs) and transport of PB across the rBMEC monolayer from apical to basolateral and basolateral to apical were evaluated in the presence of VER. The effect of VER on PB pharmacological activity on the central nervous system (CNS) and brain distribution of PB in mice were further investigated.

Berberine suppresses intestinal disaccharidases with beneficial metabolic effects in diabetic states, evidences from in vivo and in vitro study.

Clinical reports have demonstrated that berberine is a potential antidiabetic agent, but the underlying mechanism is unclear. The purpose of this study was to investigate if berberine exerts its hypoglycemic action via inhibiting intestinal disaccharidases using in vivo and in vitro experiments. Streptozotocin-induced diabetic rats received berberine (100 or 200 mg/kg) orally once daily or acarbose (40 mg/kg) orally twice daily for 5 weeks.

Huang-lian-jie-du-decoction modulates glucagon-like peptide-1 secretion in diabetic rats.

Aim Of The Study: Huang-lian-jie-du-decoction (HLJDD), a well-known Chinese herbal formula, has been used for diabetic treatment. The purpose of the study was to investigate whether HLJDD affected glucagon-like peptide (GLP)-1 (7-36) amide level in diabetic rats.

Materials And Methods: Streptozotocin (STZ)-induced diabetic rats were treated with HLJDD at low dose (2 g/kg/day) or high dose (4 g/kg/day).

Berberine promotes glucagon-like peptide-1 (7-36) amide secretion in streptozotocin-induced diabetic rats.

Berberine (BBR), a hypoglycemic agent, has shown beneficial metabolic effects for anti-diabetes, but its precise mechanism was unclear. Glucagon-like peptide-1 (GLP-1) is considered to be an important incretin that can decrease hyperglycemia in the gastrointestinal tract after meals. The aim of this study was to investigate whether BBR exerts its anti-diabetic effects via modulating GCG secretion.
