Filter by:The purpose of this study is to establish the large COPD cohort and biological database in China, aiming for precision medicine to optimize diagnosis and treatment choices and to monitor and improve clinical outcomes in this disease.
With the comparative effectiveness research methods and hospital registration study approach, the purpose of this study is to objectively record the methods, efficacy and its influencing factors of COPD commonly used treatment methods/programs (Western medicine, Traditional Chinese Medicine and Integrative Medicine) in the actual medical environment, analysis of application characteristics for the different programs, and provide the basis for its revision and promotion. It is a first registration study for COPD in China.
The purpose of this study is to determine whether cell therapy with autologous adult stem cells (from bone marrow and/or fat) is safe in the treatment of advanced Chronic Obstructive Pulmonary Disease (COPD).
A preliminary study to evaluate a new nasal interface and portable ventilator system in comparison to standard oxygen therapy in patients with severe chronic lung disease.
This is an observational study aiming to identify and validate biomarkers (including imaging and clinical descriptors) for chronic obstructive pulmonary disease (COPD), cardiovascular disease (CVD) and lung cancer.
- Pulmonary diseases are increasingly important causes of morbidity and mortality in the modern world. - Sildenafil, an orally administered a phosphodiesterase type 5 (PDE-5) inhibitor, targets the nitric oxide (NO) pathway. The drug was first approved for the treatment of Pulmonary Arterial Hypertension (PAH) in 2005. - The aim of the suggested study is to examine the acute effect of oral intake of sildenafil on exercise tolerance and functional capacity in Chronic Obstructive Pulmonary Disease (COPD), Idiopathic pulmonary fibrosis (IPF) and post Pneumonectomy patients. - The investigators hypothesize that oral ingestion of sildenafil prior the exercise may enhance exercise tolerance and improve function in COPD, IPF and post Pneumonectomy patients. - Patients and Methods: Sixty chronic lung disease patients males and females (aged 30 to 90 years) 20 COPD (GOLD III-IV) [9, 39] , 20 IPF and 20 post Pneumonectomy patients will be recruit to this study. - All subjects will carried out two maximal cardiopulmonary exercise tests (CPET) on bicycle ergometer in different days; 60 min after intake of placebo and 60 min after intake of 100 mg sildenafil (Pfizer, Sandwich, UK), in random order. - In first meeting prior exercise test at rest standard pulmonary function test, diffusion of CO, TLC and RV will be measured. In addition, Doppler Echocardiography and blood samples for NT-proBNP will be taken prior and post each CPET. - After 15-20 minute of passive recovery post exercise test all patients will perform 3 short functional tests including 6 minute walk test to assess functional capacity.
