Objective To investigate the potential suppression role of Pingchuan-Guben Decoction in airway chronic inflammation and remodeling by observing the expression of vascular endothelial growth factor (VEGF) and NF-κB on the mice asthma model Methods Forty Kunming mice were randomly divided into three groups.Those were negative control group(A),asthma model group(B),Pingchuan-Guben Decoction group (C),and every group was 8 mice.Total and differential cells were counted from bronchoalveolar lavage fluid (BALF).Histological examination(HE) was performed to observe the general pathologic alteration and analyze the thickness of airway wall.The protein expression of VEGF and NF-κB were detected by immunohistochemistry.Results (1)HE staining showed that compared with the Pingchuan-Guben Decoction group,there were a large number of inflammatory cells infiltration,heavier smooth muscle hypertrophy and mucous membrane hyperemia in mice of the asthma group,(2) The Eosinophil cell counting in BALF,airway wall thickness NF-κB,VEGF expression levels in rats asthma model group were (2.15 ± 0.44) × 108/L,(16.66 ± 1.52) μm2/μm,(36.01 ± 4.78),(35.87 ± 4.92) respectively,significantly higher than that in control group ((0.03 ±0.03) × 108/L,(6.61 ± 1.14) μm2/μm,(12.78 ± 1.47),(11.57 ± 1.64) ;P ＜ 0.01).The Eosinophil cell counting in BALF,airway wall thickness NF-κB,VEGF expression levels in Pingchuan-Guben Decoction group were (0.35 ± 0.12) × 108/L,(11.57 ± 1.26) μm2/μm,(29.13 ± 1.92),(28.28 ± 2.02) respectively,significantly higher than that in rats asthma model group (P ＜ 0.01).Conclusion PingchuanGuben Decoction can decrease NF-κB and VEGF expression of asthma mice,and then inhibits airway chronic inflammation and remodeling.
