Mechanism of Qingfei Huatan Zhuyu Decoction in Treatment of COPD Based on "Lung and Intestinal Co-treatment"
To observe the effect of Qingfei Huatan Zhuyu decoction on the lung and intestinal function of rats with chronic obstructive pulmonary diseases (COPD) and explore the deep-seated mechanism of its embodiment of lung and intestinal co-treatment.
Method
2
A total of 60 Wistar rats were randomly divided into six groups, with 10 rats in each group, and the groups were control group, model group, acute syrup group (10 g·kg
-1
·d
-1
), and low, medium, and high-dose groups (10, 15, 20 g·kg
-1
·d
-1
) of Qingfei Huatan Zhuyu decoction. The COPD rat model was established by lipopolysaccharide tracheal drip combined with the smoke inhalation method, and the acute syrup group and the Qingfei Huatan Zhuyu decoction group were administered by gavage with corresponding dose concentrations respectively, while the rest groups were controlled by saline gavage, and the lung function and blood gas indexes of rats were monitored after the last administration. The histopathological changes in the lung and intestine were observed microscopically. The expression of serum interleukin-6 (IL-6), tumor necrosis factor-
α
(TNF-
α
), and secretory immunoglobulin A (IgA) in colon tissue were measured by enzyme-linked immunosorbent assay (ELISA). The biochemical indexes such as serum diamine oxidase (DAO),
D
-lactic acid, and malondialdehyde (MDA) were measured. Immunohistochemistry was used to detect the expression of tight junction protein (Occludin) in rat colon tissue. The expression of F4/80 positive alveolar macrophages in rat lung tissue, and the expression of
α
-actin (
α
-SMA) and colonic atresia small band protein-1 (ZO-1) were determined by immunofluorescence. The protein expression of p-NF-
κ
B p65, NF-
κ
B p65, p-p38 MAPK, and p-p38 MAPK and the expression of Occludin and ZO-1 in colon tissue were detected in rat lung tissue by Western blot.
Result
2
Compared with the normal group, the model group had pulmonary dysfunction, reduced forced vital capacity (FVC), arterial partial oxygen pressure (PaO
2
), arterial oxygen saturation (SaO
2
), and dynamic lung compliance (Cdyn) (
P
<
0.01), and the pathological changes in the lung and intestine were obvious. The expressions of IL-6, TNF-
α
, DAO,
D
-lactic acid, and MDA in serum were increased (
P
<
0.05,
P
<
0.01), and the protein expression ratio of p-NF-
κ
B p65/NF-
κ
B p65 and p-p38 MAPK/p38 MAPK in lung tissue was increased. The expression of F4/80 positive macrophages in lung tissue was enhanced. The expression of IgA, Occludin, and ZO-1 in colon tissue decreased (
P
<
0.05,
P
<
0.01). Compared with the model group, the pulmonary function of the rats in the acute syrup group and groups of Qingfei Huatan Zhuyu decoction was significantly improved, and the FVC, PaO
2
, SaO
2
, and Cdyn were increased (
P
<
0.05,
P
<
0.01). The pathological changes in the lung and intestine were significant. The expressions of IL-6, TNF-
α
, DAO,
D
-lactic acid, and MDA in serum were decreased (
P
<
0.05,
P
<
0.01), and the expressions of F4/80 positive macrophages in lung tissue were decreased (
P
<
0.01). The protein expression ratio of p-NF-
κ
B p65/NF-
κ
B p65 and p-p38 MAPK/p38 MAPK in lung tissue decreased (
P
<
0.01), and the expression of IgA, Occludin, and ZO-1 in colon tissue increased (
P
<
0.01).
Conclusion
2
Qingfei Huatan Zhuyu decoction can effectively reduce the symptoms of COPD rats, and its mechanism of action is related to inhibiting the inflammatory response of lung tissue and improving the barrier function of the intestinal mucosa.
