Chronic obstructive pulmonary disease (COPD) is associated with cognitive decline, but the molecular link between COPD and dementia or Alzheimer’s disease (AD) remains unclear. This study was aimed to investigate whether serum Aβ levels are correlated with COPD. 77 cognitively normal COPD patients and 45 age- and gender-matched normal controls were admitted(More)
Investigations into the structure-activity relationships (SAR) of a series of phthalazine-based inhibitors of p38 are described. These efforts originated from quinazoline 1 and through rational design led to the development of a series of orally bioavailable, potent, and selective inhibitors. Kinase selectivity was achieved by exploiting a collection of(More)
OBJECTIVE To observe the changes of apoptosis and proliferation of pulmonary tissue cells in rats with chronic obstructive pulmonary disease (COPD). METHODS The rat model of COPD was established by exposure to cigarette smoking. Thirty-three Wistar rats were randomly divided into a normal control (NC) group, a smoking inhalation for 1 month (COPD-1) group(More)
We reported a previously healthy 25-year-old female patient who developed hypersensitivity pneumonitis following repeated exposures to the smoke of mosquito coils. The patient presented with vague symptoms of cough and fever for 3 days. Diagnostic criteria proposed for clinical use in this case included history, exposure to a recognized antigen, physical(More)
The p38 mitogen-activated protein kinase (MAPK) is a central signaling molecule in many proinflammatory pathways, regulating the cellular response to a multitude of external stimuli including heat, ultraviolet radiation, osmotic shock, and a variety of cytokines especially interleukin-1beta and tumor necrosis factor alpha. Thus, inhibitors of this enzyme(More)
A one-pot procedure for the synthesis of 2-alkyl-2-arylcyanoacetates based on a Pd(OAc)2/DPPF (DPPF = 1,1'-diphenylphosphino ferreocene)-catalyzed enolate arylation followed by in situ alkylation has been developed. This procedure tolerates a diverse range of aryl and heteroaryl bromides, and provides a rapid entry to a variety of(More)
The present report describes a case of diffuse panbronchiolitis (DPB) in a child from Western China and the favorable outcome associated with early diagnosis. DPB is an uncommon presentation in pediatric patients. A 13-year-old Chinese boy was admitted to the respiratory outpatient department due to recurrent cough and progressive exertional dyspnea that(More)
