Effect of Combined Therapy of Lung and Intestine on NF-κB Inflammatory Pathway and Macrophage Polarization in LPS-induced Acute Lung Injury Rats
To investigate the effect of combined therapy of lung and intestine (Mahuangtang + Da Chengqitang) on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in rats and its protective mechanism.
Method
2
Wistar rats were randomly divided into blank group, model group, low-, medium-, and high-dose groups with combined therapy of lung and intestine , and dexamethasone group. LPS (10 mg·kg
-1
) was given (
ip
) to induce ALI in rats. The general state of rats in each group was observed and recorded. The body temperature of rats in each group was recorded 0-8 h after modeling by means of anal temperature measurement. Serum and lung tissues were collected 24 h after modeling. Serum levels of interleukin-1
β
(IL-1
β
), tumor necrosis factor-
α
(TNF-
α
), interleukin-10 (IL-10), and arginase-1 (Arg-1) were determined by enzyme-linked immunosorbent assay (ELISA). Western blot was used to detect the protein levels of nuclear factor kappa B p65 (NF-
κ
B p65), phosphorylated NF-
κ
B p65 (p-NF-
κ
B p65), NF-
κ
B inhibitor
α
(I
κ
B
α
), and phosphorylated I
κ
B
α
(p-I
κ
B
α
) in lung tissues of rats. The levels of classically activated (M1) macrophage marker CD80 and IL-1
β
and macrophage markers F4/80 and IL-10 were detected by double immunofluorescence.
Result
2
Compared with the blank group, the model group showed increased body temperature and thermal response index (TRI), elevated serum levels of pro-inflammatory factor TNF-
α
and IL-1
β
and anti-inflammatory factor IL-10 (
P
<
0.01), up-regulated protein levels of p-NF-
κ
B p65 and p-I
κ
B
α
in lung tissues (
P
<
0.01), and increased levels of F4/80, CD80, and IL-1
β
in lung tissues (
P
<
0.01). Compared with the model group, the lung-intestine combined treatment groups and the dexamethasone group exhibited decreased body temperature and TRI in rats (
P
<
0.01), declined serum levels of inflammatory factor TNF-
α
and IL-1
β
(
P
<
0.05,
P
<
0.01), elevated serum levels of anti-inflammatory factor IL-10 and Arg-1 (
P
<
0.05,
P
<
0.01), down-regulated protein levels of p-NF-
κ
B p65 and p-I
κ
B
α
in lung tissues (
P
<
0.05,
P
<
0.01), decreased levels of CD80 and IL-1
β
, and increased levels of IL-10 in lung tissues (
P
<
0.01), while the level of F4/80 was not significantly changed.
Conclusion
2
The combined therapy of lung and intestine can obviously alleviate the fever and inflammatory state of ALI rats, and the mechanism may be related to the inhibition of NF-
κ
B inflammatory pathway and the polarization of lung tissue macrophages to anti-inflammatory phenotype.
