Expression levels of induced sputum IL-8 and IL-10 and drug intervention effects in patients with acute exacerbated COPD complicated with chronic cor pulmonale at high altitude

The aim of this study was to assess the expression levels of induced sputum interleukin (IL)‑8 and IL‑10 levels in patients with acute exacerbated chronic obstructive pulmonary disease (AECOPD) complicated with chronic cor pulmonale (CCP) at high altitude, and to evaluate the intervention effects of an inhaled corticosteroid (ICS) and a β2‑adrenoceptor agonist in this disease. A total of 186 patients with AECOPD complicated with CCP were...
