Caffeic acid phenethyl ester alleviates asthma by regulating the airway microenvironment via the ROS-responsive MAPK/Akt pathway.

In the pathophysiology of asthma, structural cell dysfunction and concomitant microenvironment changes in airways are crucial to pathological progression, which involves oxidative stress. Caffeic acid phenethyl ester (CAPE) is an active anti-oxidative component obtained from propolis, and has been shown to have beneficial effects on several respiratory disorders, such as chronic obstructive pulmonary disease and lung cancer. However, the impact of CAPE on asthma is not well understood.

Morin Attenuates Ovalbumin-Induced Airway Inflammation by Modulating Oxidative Stress-Responsive MAPK Signaling.

Asthma is one of the most common inflammatory diseases characterized by airway hyperresponsiveness, inflammation, and remodeling. Morin, an active ingredient obtained from Moraceae plants, has been demonstrated to have promising anti-inflammatory activities in a range of disorders. However, its impacts on pulmonary diseases, particularly on asthma, have not been clarified.

Galangin attenuates airway remodelling by inhibiting TGF-β1-mediated ROS generation and MAPK/Akt phosphorylation in asthma.

Galangin, a natural flavonol, has attracted much attention for its potential anti-inflammatory properties. However, its role in the regulation of airway remodelling in asthma has not been explored. The present study aimed to elucidate the effects of galangin on chronic inflammation and airway remodelling and to investigate the underlying mechanisms both in vivo and in vitro.

Elimination of central sleep apnea by cardiac valve replacement: a continuous follow-up study in patients with rheumatic valvular heart disease.

Background: Recent studies have suggested that cardiac surgery may affect sleep-disordered breathing (SDB) in chronic heart failure patients. However, the dynamic changes in sleep apnea and heart function after cardiac surgery and the mechanisms responsible for these changes remain unknown.

Methods: Patients with rheumatic valvular heart disease (RVHD) and SDB were enrolled and followed up at three, six and 12 months after cardiac valve replacement (CVR).

[Flexible bronchoscopic intervention for endobronchial hamartoma].

Objective: To evaluate the effectiveness and safety of interventional treatment in the removal of endobronchial hamartoma by flexible bronchoscopy.

Methods: A retrospective analysis was conducted in 8 inpatients with histologically confirmed endobronchial hamartoma , diagnosed between May 2009 to January 2012 in the First Affiliated Hospital of Nanjing Medical University. The clinical, radiological and bronchoscopic features of hamartoma, and the clinical outcomes after bronchoscopic intervention were described.

Invasive examinations in patients with suspected lung cancer: more may be too many.

The recent article entitled "Principles of biopsy in suspected lung cancer: priority still based on invasion in the era of targeted therapy?" published in Journal of Thoracic Disease by Chen et al., concluded the principles of biopsy in suspected lung cancer should be prioritized in sequence based on weight in clinical management, acquisition of tissue, invasion, efficiency and cost. We reported a patient with a 30-year history of pulmonary silicosis, had been found no evidence of tumor after receiving a series of invasive examinations.

Galangin Abrogates Ovalbumin-Induced Airway Inflammation via Negative Regulation of NF-κB.

Persistent activation of nuclear factor κB (NF-κB) has been associated with the development of asthma. Galangin, the active pharmacological ingredient from Alpinia galanga, is reported to have a variety of anti-inflammatory properties in vitro via negative regulation of NF-κB. This study aimed to investigate whether galangin can abrogate ovalbumin- (OVA-) induced airway inflammation by negative regulation of NF-κB.
