BACKGROUND Chronic obstructive pulmonary disease (COPD) is characterised by airflow limitation, and has many components including mucus hypersecretion, oxidative stress, and airway inflammation. We aimed to assess whether carbocisteine, a mucolytic agent with anti-inflammatory and antioxidation activities, could reduce the yearly exacerbation rate in(More)
BACKGROUND There is increasing evidence for a possible association between chronic obstructive pulmonary disease (COPD) and the use of biomass fuels for cooking and heating in developing countries. Data on the prevalence of COPD and objective measurements of indoor pollution from biomass fuel have not been widely available from China. A study was undertaken(More)
OBJECTIVE To evaluate the effects of a community based integrated intervention for early prevention and management of chronic obstructive pulmonary disease (COPD) in China. DESIGN Cluster randomised controlled trial. SETTING Eight healthcare units in two communities. PARTICIPANTS Of 1062 people aged 40-89, 872 (101 with COPD and 771 without COPD) who(More)
BACKGROUND Lung cancer is the most common malignancy in humans and its high fatality means that no effective treatment is available. Developing new therapeutic strategies for lung cancer is urgently needed. Malaria has been reported to stimulate host immune responses, which are believed to be efficacious for combating some clinical cancers. This study is(More)
OBJECTIVE To investigate the local epidemiology of Klebsiella penumoniae carrying bla(CTX-M-15) in southern China and to characterize the genetic environment of bla(CTX-M-15). METHODS PCR and DNA sequencing were used to detect and characterize the genetic contexts of bla(CTX-M-15). The clonal relatedness of isolates carrying bla(CTX-M-15) was determined(More)
The novel avian origin influenza A (H7N9) virus has caused severe diseases in humans in eastern China since the spring of 2013. Fatal outcomes of H7N9 infections are often attributed to the severe pneumonia and acute respiratory distress syndrome (ARDS). There is urgent need to discover biomarkers predicting the progression of disease and fatal outcome of(More)
BACKGROUND Indacaterol is a novel, once-daily (od), inhaled, long-acting β(2)-agonist bronchodilator for maintenance treatment of airflow limitation in patients with COPD. The aim of this study was to evaluate the efficacy of indacaterol on dyspnea, using available randomized placebo-controlled trials. METHODS A systematic search was made of MEDLINE,(More)
Oxidative stress is an important part of host innate immune response to foreign pathogens. However, the impact of vitamin C on oxidative stress and inflammation remains unclear in community-acquired pneumonia (CAP). We aimed to determine the effect of vitamin C on oxidative stress and inflammation. CAP patients were enrolled. Reactive oxygen species (ROS),(More)
BACKGROUND The current Global initiative for chronic Obstructive Lung Disease (GOLD) treatment strategy recommends the use of one or more bronchodilators according to the patient's airflow limitation, their history of exacerbations, and symptoms. The LANTERN study evaluated the effect of the long-acting β2-agonist (LABA)/long-acting muscarinic antagonist(More)
BACKGROUND Despite the rapid increase in research in China, little is known about the quality of clinical trials conducted there. METHODS A systematic review and critical appraisal of randomised controlled trials (RCTs) conducted in China and published in 2004 was undertaken to describe their characteristics, assess the quality of their reporting, and(More)
