Objective:
2
To investigate the effect and mechanism of Xiaoyaosan on lipopolysaccharide(LPS)-induced nerve injury.
Method:
2
The 56 rats were randomly divided into control group
sham group
model group
amitriptyline group (10mg·kg
-1
)
fluoxetine group (10mg·kg
-1
)
Xiaoyaosan group high and low-dose (30
15g·kg
-1
). The nerve injury model rat were established by LPS injection into lateral ventride
rats were administrated for 14 days by gavage. The levels of brain-derived neurotrophic factor (BDNF) and
β
-nerve growth factor (
β
-NGF) in serum were detected by enzyme linked immunosorbent assay(ELISA)
and the expressions of BDNF
nerve growth factor (NGF)
tropomyosin receptor kinase B (TrkB)
tropomyosin receptor kinase A (TrkA)
cAMP response element-binding protein (CREB) mRNA in hippocampus and cortex were detected by Real-time PCR.Protoin expression of BDNF
TrkB
CREB
p-CREB
postsynaptic density protein 95 (PSD95)
synaptophysin (SYP) in hippocampus and cortex were detected by Western blot.
Result:
2
Compared with control group
LPS decreased the level of BDNF and
β
-NGF in serum(
P
<
0.01)
reduced the expression of BDNF
NGF
TrkB
TrkA
CREB mRNA and the expression of BDNF
TrkB
CREB
Phospho-CREB (p-CREB)
PSD95
SYP in hippocampus and cortex(
P
<
0.05
P
<
0.01). Compared with model group
levels of BDNF and
β
-NGF in serum in Xiaoyaosan high and low-dose group were increased significantly (
P
<
0.05
P
<
0.01)
and expressions of BDNF
NGF
TrkB
TrkA
CREB
PSD95
SYP in hippocampus and cortex were increased significantly (
P
<
0.05
P
<
0.01).
Conclusion:
2
Xiaoyaosan has a certain antagonistic effect on LPS inducednerve injury
which suggests that the effect is related to activate BDNF/NGF-TrkB/TrkA-CREB pathway and upregulated the expression of synaptic protein.
