[Effect of yifei jianpi recipe on inflammatory cells, levels of interleukin-8 and tumor necrosis factor-alpha in sputum from patients with chronic obstructive pulmonary disease].

Objective: To explore the effect and the mechanism of yifei jianpi recipe (YFJPR) on patients with chronic obstructive pulmonary disease (COPD).

Methods: Forty patients with COPD in stable phase were randomly divided into two groups, the treated group and the control group. Indexes including the total and differential count of inflammatory cell in sputum, levels of interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-alpha), as well as the percentage of forced expiratory volume in one second in its predicted value (FEV1%) and ratio of FEV1/forced vital capacity (FVC) in patients were measured before and after treatment, and compared with those in 20 healthy subjects.
