），白三烯B

（LTB

）以及白三烯C

（LTC

）的影响。

方法

原代培养气道上皮细胞和AECOPD气道上皮细胞，另将60只SPF级雄性SD大鼠随机分为6组清金化痰汤高、中、低剂量组、罗红霉素组、模型组以及正常组，各10只。除正常组外，其余各组采用脂多糖（LPS）气管滴入法+烟熏联合方法构建AECOPD模型。造模后清金化痰汤高、中、低剂量组分别灌胃给予30，15 ，7.5 g·kg

Abstract

Objective

To regulate autophagy protein p62 of airway epithelial cells in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) rats with Qingjin Huatantang

in order to explore its effect on interleukin (IL) -1

and tumor necrosis

tumor necrosis factor-

(TNF-

)

leukotriene B

(LTB

)

and leukotriene C

(LTC

Method

Airway epithelial cells and AECOPD airway epithelial cells were cultured. Sixty SPF male SD rats were randomly divided into 6 groups

namely high

medium and low-dose Qingjin Huatantang groups

western medicine group

model group and normal group. Except for the normal group

the remaining groups were included into the AECOPD model by lipopolysaccharide (LPS) tracheal instillation method + fumigation method. After modeling

the dosage of the high-dose traditional Chinese medicine group was 30 g·kg

that of the middle-dose group was 15 g·kg

that of the low-dose group was 7.5 g·kg

the positive control group was given luo erythromycin (0.017 5 g·kg

)

the model group and the blank control group were orally given normal saline with the volume of 20 mL·kg

. Serum was extracted two weeks after administration

and the cells were intervened with drug-containing serum. The content of interleukin IL-1

TNF-

and LTB

in cell supernatants were detected by enzyme-linked immunosorbent assay (ELISA). And LTC

content

p62 mRNA and protein expressions in lung airway epithelial cells were detected by quantitative real-time fluorescence polymerase chain reaction (Real-time PCR) and Western blot.

Result

Compared with the normal group

ELISA results showed that IL-1

TNF-

LTB

and LTC

in the model group were significantly increased (

0.01). Compared with the model group

IL-1

TNF-

LTB

LTC

in cell supernatants in each administration group were significantly reduced (

0.01)

mRNA and protein expressions in p62 showed that compared with the normal group

mRNA and protein expressions in p62 of model group significantly decreased (

0.01). Compared with the model group

the mRNA and protein expressions of p62 in each administration group significantly increased to different degrees (

0.01). The expression of autophagy in Qingjin Huatantang high-dose group and western medicine group was comparable.

Conclusion

Qingjin Huatantang can reduce the inflammatory response in airway epithelial cells

which may be related to the regulation of autophagy protein p62.
