About this study

Official title: Studies in Pulmonary Inflammation and the Effectiveness of Pulmonary Recovery in COPD Patients:the Mechanism of Proteoglycan 4

The investigators previous research has demonstrated that proteoglycan 4 (PRG4) may be a biomarker for identification of severity in COPD. PRG4 was more sensitive and specific than CRP for confirming COPD severity and acute exacerbation frequency. It was related to the 1-year force vital capacity decline in COPD patients. The past study found that Prg4 is an immunomodulatory factor regulating parathyroid hormone actions on hematopoietic cells in mice. Previous report showed that voluntary wheel running and fluid flow shear stress that promote the expression of the Prg4 and association with pulmonary inflammation. COPD patients are characterized by a progressive decrease of lung function that is associated with increased in the airway and systemic inflammation. Pulmonary recovery (PR) is able to decrease acute exacerbation, maintain pulmonary function, increase exercise tolerance and improve quality of life in COPD patients, but it is unknown the mechanism of PRG4. The current study aimed to study in the pulmonary inflammation and the effectiveness of pulmonary recovery in COPD Patients:The mechanism of PRG 4.

  1. Proteoglycan 4 is correlated with pulmonary inflammation and decline of pulmonary function in the different phenotype of COPD. 1-1 Classification of characteristic、the severity of disease、pulmonary functional test、exercise capacity and blood sample collection for routine analysis. 1-2 Human blood bio-bank and molecular analysis: PRG4、IL-6、IL-8、TNFα、CRP\& IL-10. 1-3 To investigate whether daily physical activity、hypoxia and hyperinflation were associated with airway inflammation and PRG4 in COPD patients.
  2. The mechanism of PRG 4 in the effectiveness of PR on the AECOPD. 2-1 The PR program: The combination effect of negative pressure ventilation and exercise training program on acute exacerbation of COPD (AECOPD). 2-2 To examine the efficacy of PR on cytokines and PRG4 protein. 2-3 Correlation between PR effects and PRG4:PR is correlation with PRG4、clinical progression、exercise tolerance、PFT change and SpO2 during exercise.
  3. In vitro cell culture research models 3-1 Pulmonary inflammatory model establishment:Human primary epithelium cell culture and Beas-2B for IL-1β、TNFα、LPS、IL-10 and H2O2 effects. 3-2 Purification of peripheral blood monocyte cells:Primary culture to evaluate pulmonary inflammation and treatment effects. 3-3 Hypoxia experiments:To test whether hypoxia induces regulation of PRG4 protein or different cytokines in epithelial cells. 3-4 Inhibit PRG4:To prove the mechanism of PRG4 under the hypoxia model by PRG4 siRNA。
  4. In vivo animal research models 4-1 Smoke-COPD mice models establishment: 4-2 To determinate the effects of exercise training in COPD mine. 4-3 To investigate on PRG4 protein in pulmonary inflammation and the effectiveness of exercise training in the tissue and serum of mice.

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The systemic inflamation biomakers (time frame: 0~12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 May 2016.
