Adipose-Derived Mesenchymal Stem Cell-Derived Exosomal miR-301a-3p Regulates Airway Smooth Muscle Cells During Asthma by Targeting STAT3.

Background: Asthma is a chronic inflammatory disease featured by inflammation and remodeling of airway. Adipose-derived mesenchymal stem cell (ADSCs)-derived exosomal miRNAs have been suggested as promising therapeutic manners for diseases.

Methods: ADSCs and airway smooth muscle cells (ASMCs) were isolated from SD rats.

HDAC8-inhibitor PCI-34051-induced exosomes inhibit human bronchial smooth muscle cell proliferation via miR-381-3p mediated TGFB3.

The present study aimed to investigate the effects of PCI-34051-induced human bronchial epithelial cells (HBECs)-derived exosomes (PCI-Exo) on human bronchial smooth muscle cells (HBSMCs) and the key exosomal miRNAs involved in this process. Blank exosomes (Exo) and PCI-Exo were extracted from HBECs treated with PBS and PCI-34051, respectively. RNA-sequencing was performed to uncover the miRNA expression profile affected by PCI-Exo.

Membranous Nephropathy Complicated with Disseminated Infection: A Case Report and Literature Review.

Disseminated infection caused by with primary nephrotic syndrome is exceedingly rare. A 66-year-old female visited the outpatient department due to fever and fatigue who had been diagnosed as membranous nephropathy and with a long-term prednisone and immunosuppressive therapy. After lung biopsy for many times, culture from space-occupying lesion of the right lung and species identification by mass spectrometry-based methods (MALDI-TOF) revealed .

Proteomics profiling asthma induced-lysine acetylation.

Asthma is a chronic inflammatory disease that has been extensively studied for many years. However, finding a complete cure remains a significant challenge. Protein acetylation, especially histone acetylation, plays a significant role in the anti-asthma process.

HDAC8 inhibitor attenuates airway responses to antigen stimulus through synchronously suppressing galectin-3 expression and reducing macrophage-2 polarization.

Background: This study was to investigate of the mechanism by which histone deacetylase (HDAC) 8 inhibitor ameliorated airway hyperresponsiveness (AHR) and allergic airway inflammation.

Methods: Mice were sensitized and then treated with budesonide (BUD) or PCI-34051 (PCI) prior to exposing to normal saline (NS) or ovalbumin (OVA). The raw264.

Treatment with eucalyptol mitigates cigarette smoke-induced lung injury through suppressing ICAM-1 gene expression.

The present study was conducted to investigate the clinical significance of Eucalyptol in treating cigarette smoke-induced lung injury with the potential mechanism involved in the event. Rats were exposed to air (control) and cigarette smoke (smoking) after they were treated with Eucalyptol (260 mg/kg) orally once a day for 12 weeks. Cell counts of bronchoalveolar lavage fluid (BALF), measurements of mean liner intercept (MLI) and mean alveolar number (MAN), and lung function test were executed in experimental animals.

Eucalyptol protects lungs against bacterial invasion through attenuating ciliated cell damage and suppressing MUC5AC expression.

This study was conducted to investigate whether eucalyptol plays a role in influencing bacterial growth in cigarette smoke-exposed lungs. Rats were exposed to air (control) and cigarette smoke (smoking) in the presence and absence of eucalyptol (260 mg/day). Morphological analysis of lung structures and status of airway mucous production were observed under microscope.

Melatonin attenuates TGFβ1-induced epithelial-mesenchymal transition in lung alveolar epithelial cells.

Idiopathic pulmonary fibrosis (IPF) is the most common interstitial lung disease. However, the pathogenesis remains to be fully elucidated. Melatonin is secreted by the pineal gland, it has a strong antioxidant effect, and exerts an anti-fibrosis effect.

Effectiveness of inhaled corticosteroids in the treatment of acute asthma in children in the emergency department: a meta-analysis.

Objectives: This meta-analysis aimed to compare the treatment of an acute asthma attack in children in the emergency department (ED) with inhaled corticosteroids (ICS) versus placebo or oral systemic corticosteroids (SC) as assessed by the hospital admission rates.

Methods: After searching Medline, Cochrane, EMBASE, and Google Scholar, we identified ten articles that described randomized controlled trials of ICS versus placebo or oral SC for treating children with asthma attacks in the ED. Primary outcome was the hospital admission rate as defined as inpatient admission or admission into intensive care unit.

Bloody pleural effusion--a rare manifestation of sarcoidosis.

Sarcoidosis is a multisystemic granulomatous disease of unknown etiology. Pleural effusion is rare in patients with sarcoidosis, occurring in 0.7% to 20% of cumulative series.

EGF-recruited JunD/c-fos complexes activate CD2AP gene promoter and suppress apoptosis in renal tubular epithelial cells.

CD2-associated protein (CD2AP) plays a critical role in the maintenance of the kidney filtration barrier. In this study, we showed that epidermal growth factor (EGF) led to an increase of the CD2AP protein and mRNA in the human renal proximal tubular epithelial cell line HK-2 cells, which was due to the elevation of CD2AP promoter activity. Upon deletion and mutation analysis, electrophoretic mobility shift assays and chromatin immunoprecipitation, an AP-1-like element within CD2AP promoter was characterized, by which EGF recruited c-fos and JunD, two components of AP-1, to the human CD2AP gene promoter and suppressed angiotensin II-induced apoptosis in HK-2 cells.

Functional characterization of the regulatory region of human CD2-associated protein promoter in HEK 293 cells.

Background: The mRNA of CD2-associated protein (CD2AP) was found to be changed in glomerular diseases. The promoter plays an important role in the regulation of gene expression, but the characterization of the human CD2AP promoter has not been systematically analyzed in HEK 293 cells.

Aims: To analyze in detail the promoter of human CD2AP in HEK 293 cells.

[Relation of resting energy expenditure to respiratory mechanics and arterial blood gases in chronic obstructive pulmonary disease patients].

Objective: To investigate the relationships of the rest energy expenditure to the respiratory mechanics and arterial blood gases in chronic obstructive pulmonary disease (COPD) patients.

Methods: Twenty six patients with COPD and 21 healthy subjects were involved in the study. The rest energy expenditure (REE), oxygen consumption (VO(2)), carbon dioxide production (VCO(2)) and respiratory quotient (RQ) were measured with indirect energy measurements of canopy test; the arterial blood gases were measured soon after energy measurements; then routine pulmonary function, P(0.
