Louqin Zhisou Decoction Inhibits Mucus Hypersecretion for Acute Exacerbation of Chronic Obstructive Pulmonary Disease Rats by Suppressing EGFR-PI3K-AKT Signaling Pathway and Restoring Th17/Treg Balance

Figure 2

Effect of LQZS on goblet cell hyperplasia in the bronchial epithelium of rats with AECOPD. Goblet cell of bronchial epithelium detected by AB/PAS-staining (magnification ×400). The positive staining was presented blue or purple. Quantification of goblet cell hyperplasia in the airway (n=6). AB/PAS-positive rates were determined by the ratio of AB/PAS-positive area to the total bronchiolar epithelial area. The values were expressed as mean ± SD. One-way ANOVA was adopted for statistical analysis. Compared to Control group P < 0.01; compared to AECOPD group P < 0.01; compared to CAM group P < 0.01.
