目的:
2
观察防风-乌梅含药血清对气道平滑肌细胞(airway smooth muscle cells,ASMCs)增殖模型表型转化调控的影响,探索防风-乌梅配伍抑制气道重塑的机制,揭示中药配伍机制。
方法:
2
采用血小板衍生因子(platelet derived growth factor,PDGF)诱导的方式建立ASMCs增殖模型;分别给予大鼠灌胃生理盐水、防风、乌梅、防风-乌梅(生药15.425,15.425,30.85 g·kg

Objective:
2
To observe the effect of Saposhnikoviae Radix-Mume Fructus containing-serum in regulating the phenotypic transformation of airway smooth muscle cells (ASMCs) proliferation model
in order to explore the mechanism of combined administration of "Saposhnikoviae Radix
Mume Fructus" in inhibiting airway remodeling
and reveal the compatibility mechanism of traditional Chinese medicine.
Method:
2
The proliferation model of ASMCs was established by platelet derived growth factor (PDGF) induction. The rats were given normal saline
Saposhnikoviae Radix-Mume Fructus
Saposhnikoviae Radix-Mume Fructus(15.425

) to prepare drug serum respectively. Four generations of logarithmic phase human bronchial smooth muscle cells (HBSMC) were collected and divided into blank control group
cell model group
normal rat serum group and normal rat serum cell model group
hormone intervention group
Saposhnikoviae Radix serum group
Mume Fructus serum group
Saposhnikoviae Radix-Mume Fructus serum group. The cells were given corresponding treatment. Immunofluorescence staining and Western blot were adopted to detect ASMCs deflating marks protein
α
-actin and osteopontin (OPN) expressions
and phenotypic transformation was observed; the levels of vascular endothelial growth factor(VEGF)
transforming growth factor-
β
(TGF-
β
) and interleukin-6(IL-6) secreted by ASMCs were detected by enzyme linked immunosorbent assay (ELISA).
Result:
2
Compared with blank group and normal rat serum group
the fluorescence intensity and protein expression of
α
-actin in model group and normal rat serum cell model group were low
whereas the fluorescence intensity and protein expression of OPN were high
and the concentrations of VEGF
TGF-
β
and IL-6 increased significantly (
P
<
0.05). Compared with model group and normal rat serum cell model group
Saposhnikoviae Radix-Mume Fructus serum group and hormone intervention group could significantly enhance the fluorescence intensity and protein expression of alpha-actin
decrease the fluorescence intensity
protein expression of OPN and concentrations of VEGF
TGF-
β
and IL-6 (
P
<
0.05).
Conclusion:
2
The combined administration of "Saposhnikoviae Radix-Mume Fructus" has an inhibitory effect on airway remodeling
which may be related to the inhibition of the transformation of ASMCs from contractile phenotype to synthetic phenotype
so as to reduce the release of active substances
such as VEGF
TGF-
β
and IL-6.
