Mechanism of Combined Therapy of Lung and Intestine in Alleviating Pulmonary Edema in Treatment of Acute Lung Injury Based on VIP/cAMP/PKA/AQPs Signaling Pathway
To explore the mechanism of the combined therapy of lung and intestine (Mahuangtang + Da Chengqitang) in alleviating pulmonary edema in rats with acute lung injury (ALI) induced by lipopolysaccharide (LPS).
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 positive control group. LPS (10 mg·kg
-1
) was given (
ip
) to induce ALI in rats. After modeling, the blank group was given normal saline (25 mL·kg
-1
), the combined therapy of lung and intestine treatment groups were given (ig) low- (5 g·kg
-1
), medium- (7.5 g·kg
-1
), and high-dose (10 g·kg
-1
) Mahuangtang and Da Chengqitang, and the positive control group was given dexamethasone (5 mg·kg
-1
). Medications were administered 0, 8, and 16 h after LPS injection for 3 times. Then lung tissue and serum were collected after administration. The lung tissues were stained with haematoxylin-eosin (HE), and the pulmonary edema score was evaluated. The dry/wet (D/W) weight ratio of lung tissues in each group was measured, and the content of serum vasoactive intestinal peptide (VIP) in rats was detected by enzyme-linked immunosorbent assay (ELISA). Western blot was used to detect the protein levels of aquaporin-1 (AQP1), AQP5, VIP, cyclic adenosine monophosphate (cAMP), phosphorylated protein kinase A (p-PKA), and PKA in lung tissues of rats in each group. The level of VIP mRNA in lung tissues of rats was detected by real-time quantitative polymerase chain reaction (Real-time PCR).
Result
2
Compared with the blank group, the model group exhibited obvious lung injury, increased edema score, decreased D/W ratio (
P
<
0.01), declined AQP1, AQP5, cAMP, and p-PKA/PKA in lung tissues (
P
<
0.05,
P
<
0.01), elevated VIP content (
P
<
0.01), and up-regulated levels of VIP protein and mRNA in lung tissues (
P
<
0.05,
P
<
0.01). Compared with the model group, combined therapy of lung and intestine treatment groups showed alleviated lung injury, increased D/W ratio (
P
<
0.01), elevated AQP1, AQP5, VIP, cAMP, and p-PKA/PKA in lung tissues (
P
<
0.05,
P
<
0.01), and up-regulated VIP levels in lung tissues (
P
<
0.05,
P
<
0.01).
Conclusion
2
The combined therapy of lung and intestine can alleviate ALI-induced lung tissue edema, and the mechanism may be related to the activation of the VIP/cAMP/PKA signaling pathway, which further promotes the expression of AQP1 and AQP5 and enhances the water metabolism of lung tissue.
