Effect of Huangqi Guizhi Wuwu Tang on Angiogenesis in Osteoarthritis
To study the effect of Huangqi Guizhi Wuwu Tang on angiogenesis of osteoarthritis with Yang deficiency and cold coagulation.
Method:
2
Totally 60 female SD rats were randomly divided into control group
model group
celecoxib group (20.82 mg·kg
-1
) and low
medium
high-dose Huangqi Guizhi Wuwu Tang groups (3.24
6.48
12.96 g·kg
-1
). All groups
except for control group
were involved in duplicating the osteoarthritis(OA) model through frozen and knee fixation
as well as 42-day cold environmental stimulation. After modeling
all drug-group rats were respectively administrated with corresponding drugs for 28 days
once a day. Meanwhile
control group and model group were given equivalent distilled water by gavage. 24 hours after the last gavage
vascular endothelial growth factor (VEGF)
prostaglandin E
2
(PGE
2
) and transforming growth factor-
β
1
(TGF-
β
1
) in serum were detected with enzyme linked immunosorbent assay(ELISA) method
VEGF expressions in cartilage and synovial with immunohistochemical method
and interleukin-17(IL-17) and VEGF levels in synovial with Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR).
Result:
2
Compared with normal group
the expression of VEGF in serum
cartilage and synovial were significantly increased (
P
<
0.01)
and PGE
2
and TGF-
β
1
expressions
IL-17 level were increased significantly (
P
<
0.01) as well. Compared with model group
VEGF in serum
cartilage and synovial were significantly decreased in the 4 drug groups. Meanwhile
PGE
2
TGF-
β
1
and IL-17 level were decreased significantly (
P
<
0.05). Among drug groups
IL-17 of high-dose group in synovial was higher than that of celecoxib group (
P
<
0.05)
and VEGF of medium and high-dose Huangqi Guizhi Wuwu Tang groups in synovial was higher than that of celecoxib group (
P
<
0.05). There was no significant difference among other drug groups.
Conclusion:
2
Huangqi Guizhi Wuwu Tang has an effect in suppressing angiogenesis of knee and alleviate cartilage lesion by regulating VEGF and its upstream cytokines PGE
2
and TGF-
β
