Tanshinone IIA is a lipid-soluble pharmacologically active compound extracted from the rhizome of Chinese herb Salvia miltiorrhiza, a well-known traditional Chinese medicine used for the treatment of cardiovascular disorders. Previous studies have identified that tanshinone IIA inhibited overexpression of miR-1 in hypoxic neonatal cardiomyocytes. This study(More)
BACKGROUND Roflumilast is the only oral phosphodiesterase 4 inhibitor indicated for use in the treatment of COPD. Previous studies of roflumilast have predominantly involved European and North American populations. A large study was necessary to determine the efficacy and safety of roflumilast in a predominantly ethnic Chinese population. METHODS In a(More)
BACKGROUND A higher slow vital capacity (VC) compared with forced vital capacity (FVC) indicates small airway collapse and air trapping. We hypothesized that a larger difference between VC and FVC (VC-FVC) would predict impaired exercise capacity in patients with chronic obstructive pulmonary disease (COPD). METHODS Pulmonary function and incremental(More)
BACKGROUND/AIMS Epoxyeicosatrienoic acids (EETs), a type of lipid mediators produced by cytochrome P450 epoxygenases, exert anti-inflammatory, angiogenic, anti-oxidative and anti-apoptotic effects. However, the role of EETs in cigarette smoke-induced lung injury and the underlying mechanisms are not fully known. The aim of this study was to explore the(More)
Cigarette smoke (CS) increases the risk of chronic obstructive pulmonary disease (COPD) by causing inflammation, emphysema, and reduced lung function. Additionally, CS can induce autophagy which contributes to COPD. Arachidonic acid-derived epoxyeicosatrienoic acids (EETs) have promising anti-inflammatory properties that may protect the heart and liver by(More)
The aim of the present study was to examine the effect and possible mechanism of salvianolic acid B (SalB) on pulmonary microcirculation disturbance induced by lipopolysaccharide (LPS) in rat. Male Sprague-Dawley rats were subjected to thoracotomy under continuous anesthesia and mechanical ventilation. Albumin leakage from pulmonary capillary and the(More)
During growth, C. botulinum is always exposed to different environmental changes, such as temperature increase, nutrient deprivation, and pH change; however, its corresponding global transcriptional profile is uncharacterized. This study is the first description of the genome-wide gene expression profile of C. botulinum in response to heat shock stress.(More)
The exact molecular mechanism that mediates hypoxia-induced pulmonary fibrosis needs to be further clarified. The aim of this study was to explore the effect and underlying mechanism of angiotensin II (Ang II) on collagen synthesis in hypoxic human lung fibroblast (HLF) cells. The HLF-1 cell line was used for in vitro studies. Angiotensinogen (AGT),(More)
BACKGROUND Response to inhaled corticosteroid (ICS)/long-acting beta2-agonist (LABA) combinations varies across ethnic groups. OBJECTIVE To investigate the efficacy and safety of the ICS/LABA combination fluticasone furoate/vilanterol (FF/VI) 100/25 μg in Asian patients with asthma. METHODS A randomized (1:1), 12-week, double-blind, placebo-controlled,(More)
BACKGROUND Histone deacetylase 2 (HDAC2) is a class I histone deacetylase family member that plays a critical role in suppressing inflammatory gene expression in the airways, lung parenchyma, and alveolar macrophages in patients with chronic obstructive pulmonary disease (COPD). However, the expression of HDAC2 in peripheral blood monocytes (PBMCs), nuclear(More)
