结果
2
与正常组比较,OVA组小鼠气道炎性细胞浸润,组织充血水肿,胶原纤维沉积;OVA+RSV组小鼠气道炎性细胞浸润,组织充血水肿较OVA组更显著;与OVA+RSV组比较,五虎汤加味组能显著改善气道周围炎性细胞浸润,组织充血水肿,胶原纤维沉积明显减轻,其中高剂量组作用更加明显。免疫组化结果显示,与正常组比较,OVA组和OVA+RSV组Muc5AC蛋白表达水平均显著升高(
P
<
0.01);与OVA+RSV组比较,五虎汤加味组可明显降低Muc5AC蛋白表达水平,其中高剂量组作用更加明显(
P
<
0.05);与五虎汤加味高剂量组比较,地塞米松组可明显降低Muc5AC蛋白表达水平(
P

Objective
2
To explore effect of modified Wuhutang on airway inflammation and expression of mucin (Muc) 5AC, signal transducer and activator of transcription 3 (STAT3), nuclear factor kappa B (NF-
κ
B), and NOD-like receptor thermal protein domain associated protein 3 (NLRP3) in respiratory syncytial virus (RSV)-infected asthmatic mice.
Method
2
Seventy male BALB/c mice of 6-8 weeks old were randomized into normal control (CON), asthma (ovalbumin, OVA), RSV infection-induced asthma (OVA+RSV), high-, medium-, and low-dose (4.08, 2.04, 1.02 g·kg
-1
·d
-1
, respectively) modified Wuhutang, and dexamethasone (Dxms, 0.1 g·kg
-1
d
-1
) groups (
n
=10). The model of asthma was established by sensitization and atomization inhalation with OVA. The RSV infection-induced asthma model was established by three consecutive RSV nasal infusions (1.0 × 10
6
PFU·mL
-1
, 50 μL). Wuhutang was administrated by gavage, and Dxms by intraperitoneal injection
.
The CON group was given the same amount of normal saline by gavage. The mice were anesthetized with 2.5% pentobarbital sodium 24 h after the last administration, and then the lung tissue was stained by hematoxylin-eosin (HE) and Van Gieson (VG) for observation of airway inflammation. The immunohistochemical assay was employed to detect the expression of Muc5AC. Western blot was employed to determine the protein levels of phosphorylated (p)-STAT3, STAT3, p-NF-
κ
B, NF-
κ
B, and NLRP3.
Result
2
Compared with the CON group, the OVA group presented airway inflammatory cell infiltration, tissue hyperemia and edema, and collagen fiber deposition. The OVA+RSV group showed severer airway inflammatory cell infiltration and tissue hyperemia and edema than the OVA group. Compared with the OVA+RSV group, modified Wuhutang alleviated the airway inflammatory cell infiltration, tissue hyperemia and edema, and collagen fiber deposition, and the high-dose group had the best performance. Compared with the CON group, the OVA group and the OVA+RSV group showed increased expression level of Muc5AC (
P
<
0.01). Compared with the OVA+RSV group, modified Wuhutang reduced the expression level of Muc5AC, and the reduction was significant in the high-dose group (
P
<
0.05). Compared with the high-dose modified Wuhutang group, Dxms lowered the expression level of Muc5AC (
P
<
0.05). Compared with the CON group, the OVA and OVA+RSV groups showed up-regulated protein levels of p-STAT3, p-NF-
κ
B, and NLRP3 (
P
<
0.05,
P
<
0.01). Compared with the OVA+RSV group, modified Wuhutang down-regulated the protein levels of p-STAT3, p-NF-
κ
B, and NLRP3 (
P
<
0.01). Compared with the high-dose modified Wuhutang group, the Dxms group showed up-regulated levels of p-STAT3, p-NF-
κ
B proteins (
P
<
0.01).
Conclusion
2
Modified Wuhutang can reduce airway inflammation and down-regulate the expression of Muc5AC, p-STAT3, p-NF-
κ
B, and NLRP3 in RSV-infected asthmatic mice, which suggests that Wuhutang reduces airway inflammation in RSV-infected asthma by regulating the STAT3/NF-
κ
B signaling pathway.
