Abstract
Objective:
2
To investigate the effect of Gancao Fuzitang on the proliferation of fibroblast-like synoviocytes (FLS) in synovial tissue of mice with adjuvant-induced arthritis (AA).
Method:
2
The 48 male Balb/c mice were randomly divided into 4 groups: normal control group
model group(arthritis induced through injection with adjuvant)
Gancao Fuzitang group and triptolide group. The normal control group and the model control group were orally given physiological saline. After the successful modeling
the mice of the other two groups were treated with Gancao Fuzitang or triptolide orally for 18 days. Then the animals were euthanized
the paw edema of the animals was measured
and arthritic ankles were observed by histological examination. Tumor necrosis factor (TNF)-
α
was examined by immunoassays. The proliferation of synovial cells of foot joints was detected by immunohistochemical expressions of Vimentin. The expressions of Cyclin D
1
proliferating cell nuclear antigen (PCNA)
p53 and p21 were detected by Western blot.
Result:
2
Compared with the normal control group
the mice of synovial hyperplasia and bone erosion in model group were obvious. The joint swelling degree
TNF-
α
level and proliferation of FLS were increased (
P
<
0.05). The expressions of Cyclin D
1
PCNA were up-regulated(
P
<
0.05)
but the expressions of p53 and p21 were down-regulated(
P
<
0.05). Compared with the model group
Gancao Fuzitang significantly alleviated joint swelling and injuries
reduced the level of TNF-
α
cell cycles (Cyclin D
1
and PCNA)
and increased protein expressions of p53 and p21 (
P
<
0.05).
Conclusion:
2
Gancao Fuzitang has a therapeutic effect on AA mice
and the mechanism might be associated with its anti-inflammatory effect and the effects in regulating Cyclin D
1
PCNA
p53 and p21 expressions and inhibiting FLS proliferation.
