Measurement of lung function in each group at different time point. (a) tidal volume (VT), (b) peak expiratory flow (PEF), (c) peak expiratory at 50 % tidal volume (EF50). The data are expressed as mean ± SEM (n = 18–20). Control: control group; Model: model group; AS: acupoint sticking group; BY: Bufei Yishen group; BY + AS: Bufei Yishen + Acupoint sticking group; APL: aminophyline group
