Bioequivalence study of fluticasone propionate nebuliser suspensions in healthy Chinese subjects.

Background: Fluticasone propionate is a synthetic trifluoro-substituted glucocorticoid, a highly selective glucocorticoid receptor agonist. Fluticasone propionate nebuliser suspensions is an inhaled corticosteroid with the low systemic bioavailability which provides a low risk (benefit outcome without the adverse effects that accompany systemically administered corticosteroids), referred as a first-line preventive agent for patients with persistent asthma. China has become one of the countries with the highest asthma mortality rate in the world in the past years.

METTL14 Promotes Ischemic Stroke-induced Brain Injury by Stabilizing HDAC3 Expression in an m6A-IGF2BP3 Mechanism.

N6-methyladenosine (m6A) modification is the most abundant post-transcriptional modification of mRNAs and has been identified to play critical roles in ischemic stroke (IS). Herein, this study aimed to investigate the function and mechanism of Methyltransferase-like 14 (METTL14) methylase in cerebral IS. Murine BV-2 microglial cell OGD/R models and rat middle cerebral artery occlusion (MCAO) models were established to mimic IS-induced neuronal damage in vitro and brain injury in vivo.

Clinical efficacy of low-intensity pulsed ultrasound in Parkinson's disease with cognitive impairment.

Low-intensity pulsed ultrasound (LIPUS) is a new technique for invasive brain stimulation and modulation that has emerged recently, but the effects in Parkinson's disease with cognitive impairment (PD-CI) have been less observed. In this study, we recruited 56 patients with PD-CI who were continuously treated with LIPUS for 8 wk, and observed the clinical efficacy of LIPUS on patients with PD-CI by comparing with the Sham stimulation continuous treatment. Fifty-six patients with PD-CI were divided into the Sham group (given Sham stimulation on top of conventional medication, = 28) and the LIPUS group (given LIPUS stimulation on top of conventional medication, = 28), and both groups continued treatment for 8 wk.

Short sleep duration is associated with worse quality of life in Parkinson's disease: A multicenter cross-sectional study.

Objective: To characterize sleep duration and investigate its association with quality of life among Parkinson's Disease (PD) patients.

Methods: In this multicenter cross-sectional study, 970 PD patients were divided into five groups based on self-reported sleep duration: <5, ≥5 to <6, ≥6 to <7, ≥7 to ≤8, and >8 h. The quality of life was evaluated using the 39-Item Parkinson's Disease Questionnaire (PDQ-39).

The Relationship Between Serum Netrin-1 Expression Levels and Prognosis in Revascularized Patients with Acute Ischemic Stroke.

Background: This study aimed to explore the relationship between serum netrin-1 expression levels and acute prognosis in patients with acute ischemic stroke (AIS) within 24 hours after revascularization.

Methods: A total of 121 revascularized patients admitted to the Jinshan Branch of the Shanghai Sixth People's Hospital, China, between July 2019 and July 2021 were selected as study subjects. The primary outcome was the modified Rankin Scale (mRS) score three months after revascularization: patients with an mRS score >2 were classified into the unfavorable prognosis group and others into the favorable prognosis group.

A series of naphthalenediimide-based metal-organic frameworks: synthesis, photochromism and inkless and erasable printing.

Three new three-dimensional metal-organic frameworks were synthesized based on a naphthalenediimide derivative ligand, all of which exhibit photochromic behaviour due to the presence of the naphthalenediimide core. Interestingly, two of them possess significant colour changes under light, excellent stability, and appropriate photochromic lifetimes, thus showing potential for application in inkless and erasable printing media.

Identification of Novel Biomarkers in Platelets for Diagnosing Parkinson's Disease.

Background: Parkinson's disease (PD) is a common neurodegenerative disease affecting the elderly, but there is no blood test for PD diagnosis in the clinic currently. This study aimed to explore promising biomarkers in platelets (PLTs) for PD diagnosis.

Methods: PLTs were isolated from whole blood samples of PD patients and healthy controls (HCs), and RNA was extracted for sequencing.

Phosphodiesterase-4D Knockdown in the Prefrontal Cortex Alleviates Memory Deficits and Synaptic Failure in Mouse Model of Alzheimer's Disease.

Phosphodiesterase 4 (PDE4)-dependent cAMP signaling plays a crucial role in cognitive impairment associated with Alzheimer's disease (AD). However, whether inhibition of PDE4 subtypes or their splice variants in the prefrontal cortex positively regulates synaptic plasticity and antioxidative stress, and reverses β-amyloid 1-42 (Aβ1-42, Aβ42)-induced cognitive impairment still need to be clarified. The present study determined whether and how PDE4D knockdown by microinjection of lenti-PDE4D-miRNA into the prefrontal cortex reversed Aβ1-42-induced cognitive impairment in behavioral, neurochemical, and molecular biology assays.

Personalized risk prediction of symptomatic intracerebral hemorrhage after stroke thrombolysis using a machine-learning model.

Background: Personalized prediction of the risk of symptomatic intracerebral hemorrhage (sICH) after stroke thrombolysis is clinically useful. Machine-learning-based modeling may provide the personalized prediction of the risk of sICH after stroke thrombolysis.

Methods: We identified 2578 thrombolysis-treated ischemic stroke patients between January 2013 and December 2016 from a multicenter database, where 70% were used to train models and the remaining 30% were used as the nominal test sets.

Gastric fundus splenosis with hemangioma masquerading as a gastrointestinal stromal tumor in a patient with schistosomiasis and cirrhosis who underwent splenectomy: A case report and literature review.

Rationale: Splenosis is the heterotopic auto-transplantation of the splenic tissues. Gastric splenosis in a rare location mimics a gastrointestinal stromal tumor (GIST). Gastric splenosis with hemangioma has not been reported throughout the literature.

An Optimization Routing Algorithm for Green Communication in Underground Mines.

With the long-term dependence of humans on ore-based energy, underground mines are utilized around the world, and underground mining is often dangerous. Therefore, many underground mines have established networks that manage and acquire information from sensor nodes deployed on miners and in other places. Since the power supplies of many mobile sensor nodes are batteries, green communication is an effective approach of reducing the energy consumption of a network and extending its longevity.

Interaction between alcohol consumption and CYP 2C19 gene polymorphism in relation to oesophageal squamous cell carcinoma.

Objectives: The purpose of this study is to explore the relationship between the interactions of CYP2C19 gene polymorphisms and several environmental factors and oesophageal squamous cell carcinoma (OSCC).

Methods: In a case-control study of OSCC patients (n = 350) and healthy controls (n = 350), we investigated the roles of polymorphism in the CYP2C19 gene by the use of polymerase chain reaction--restriction fragment length polymorphism (PCR - RFLP) analysis.

Results: The CYP2C19(*)3 AG+AA genotype was significantly more prevalent in OSCC patients (10.

Regulation of inflammatory mediators in lipopolysaccharide-stimulated RAW 264.7 cells by 2''-hydroxy-3''-en-anhydroicaritin involves down-regulation of NF-kappaB and MAPK expression.

2''-hydroxy-3''-en-anhydroicaritin, a flavone, was isolated from the Chinese medicinal herb Epimedium brevicornum for the first time. In our previous study, we have carried out a screening program to identify the anti-inflammatory potentials of 2''-hydroxy-3''-en-anhydroicaritin. In the present study, we further found that this compound regulated lipopolysaccharide (LPS)-induced levels of nitric oxide (NO), and prostaglandin E(2) (PGE(2)) (**p<0.

Isolation of two new prenylflavonols from Epimedium brevicornum and their effects on cytokine production in vitro.

In an attempt to search for bioactive natural products, two new prenylflavonols, 2''-hydroxy-3''-en-anhydroicaritin (1) and 2''-hydroxy-beta-anhydroicaritin (2), were isolated from the Chinese medicinal herb Epimedium brevicornum. Their structures were determined by 1D and 2D NMR spectroscopic analysis. The effects of compounds 1 and 2 on cytokine production in vitro were investigated.
