Evaluation of Reactive Oxygen Metabolites in the Value of COPD

19. november 2014 oppdatert av: Jie liu, Beijing Chao Yang Hospital

System Evaluation of Reactive Oxygen Metabolites in the Value of Chronic Obstructive Pulmonary Disease

This study through the long-term observation followed up for 2 years to find the change of the COPD patients blood ROMs, systematically evaluate the relationship between ROMs and the severity of COPD. Evaluate the differences of prognosis between the different oxidative stress level (according to the level of ROMs are divided into higher and normal phenotype). Explore the new oxidative stress evaluation index ROMs application value in COPD.

Detaljert beskrivelse

Reactive oxygen metabolites (reactive oxygen metabolites, ROMs) test is a method by measuring the total reactive oxygen metabolites (ROMs) content in blood so as to evaluate the overall level of oxidative stress in the human body .Our previous studies have established the method of detecting ROMs which is suitable for fully automatic biochemical analyser.Our study through the long-term observation followed up for 2 years to find the change of the COPD patients blood ROMs, systematically evaluate the relationship between ROMs and the severity of COPD. Evaluate the differences of prognosis between the different oxidative stress level (according to the level of ROMs are divided into higher and normal phenotype). Explore the new oxidative stress evaluation index ROMs application value in COPD.

Kohorter og intervensjoner

Gruppe / Kohort
Stability in patients with COPD Those patients diagnosed COPD according to the GOLD guideline and without acute exacerbation within one month.
AECOPD the diagnosis of an exacerbation relies exclusively on the clinical presentation of the patient complaining of an acute change of symptoms (baseline dyspnea, cough, and/or sputum production) that is beyond normal day-to-day variation.
Healthy persons without smoking The healthy people who do not smoke
Healthy persons with smoking Healthy persons who smoke
