BACKGROUND AND OBJECTIVE Adrenergic β2 receptors (ADRB2) play an important role in regulating pulmonary function. Many previous studies have investigated possible associations between polymorphisms in the ADRB2 gene and asthma, but have yielded conflicting results. Furthermore, little is known regarding the possible role of the Arg19Cys polymorphism in(More)
OBJECTIVE To observe the efficacy of combination therapy with inhaled salmeterol/fluticasone and tiotropium in reducing the frequency of acute episodes of symptom exacerbation and improving lung function and health status in chronic obstructive pulmonary disease (COPD). METHODS One hundred and twenty-six patients (M/F: 92/34) with COPD were treated in a(More)
OBJECTIVE To investigate the relationship between the polymorphism of beta 2 adrenergic receptor (beta 2 AR) at loci 16, 27 and the nocturnal asthma phenotype. METHODS Forty-nine asthmatic patients were divided into nocturnal asthmatic group (n = 25) and non-nocturnal asthmatic group(n = 24) by their peak expiratory flow rates (PEFR). The genotypes at(More)
Cancer stem cells (CSCs) are responsible for tumorigenesis and recurrence, so targeting CSCs is an effective method to potentially cure cancer. BTB/POZ domain-containing protein 7 (Btbd7) has been found in various cancers, including lung cancer and liver cancer, but the role of Btbd7 in non-small cell lung cancer (NSCLC), CSC self-renewal, and(More)
BACKGROUND Recent studies have suggested that susceptibility to chronic obstructive pulmonary disease (COPD) might be related to the length polymorphism of (GT)(n) repeat in the 5'-flanking region of heme oxygenase-1 (HOX-1) gene. However, there has been no research about the relationship between the polymorphism of HOX-1 gene and severity of COPD. (More)
BACKGROUND The role of the antioxidant N-acetylcysteine (NAC) in the treatment of chronic obstructive pulmonary disease (COPD) has not been clarified as yet. In early studies, we found that the proportion of smokers with COPD having extremely slow/slow microsomal epoxide hydrolase (EPHX1) enzyme activity is significantly higher than that in healthy smokers.(More)
To discuss the differences in protein expression among tuberculosis pleural effusion (TBPE), malignant pleural effusion (MPE) and transudative pleural effusion (TSPE). We recruited 50 patients with pleural effusion, including 20 TBPEs, 17 MPEs and 13 TSPEs. Using the two-dimensional electrophoresis (2-DE) and matrix-assisted laser desorption ionization-time(More)
BACKGROUND Heme oxygenase-1 (HO-1) plays a protective role as an antioxidant in the lung, and HO-1 gene promoter polymorphism has been shown to be associated with the severity and prognosis of COPD patients. N-acetylcysteine (NAC), an antioxidant/mucous modifier, has shown an uncertain benefit in COPD patients. We hypothesized that this polymorphism could(More)
