方法：

将SPF级健康成年雌性Wistar大鼠应用弗氏完全佐剂和牛Ⅱ型胶原制备CFA动物模型。根据随机数字表，将大鼠随机分为正常组、模型组、小柴胡汤低、中、高剂量组、雷公藤多苷组。各组于造模后7 d开始灌胃给药，正常组及模型组均予注射用水，小柴胡汤低、中、高剂量组(5.94，11.88，23.76 g·kg

Abstract

Objective:

To observe the expression of tumor necrosis factor receptor-associated death domain (TARDD)

nuclear transcription factor-

B inhibiting protein

B kinase-

(IKK

) and nuclear transcription factor (NF)-

B p65 protein in the NF-

B signaling pathway of synovial tissues of complete Freund's adjuvant (CFA) rats after treatment with Xiao Chaihutang (XCHT).

Method:

In animal experiments

SPF health adult female Wistar rats were used to prepare the CFA animal model of rats with rheumatoid arthritis with Freund's complete adjuvant and cattle Ⅱ collagen type. According to the random number table

the rats were randomly divided into the normal group

the model group

the low-dose XCHT group

the medium-dose XCHT group

the high-dose XCHT group

and the Tripterygium glucosides group. The drugs were given at 7 d after the model was built. Both normal group and model group were given water for injection

and low-dose XCHT group(5.94 g·kg

-1

)

medium-dose XCHT group(11.88 g·kg

-1

)

high-dose XCHT group(23.76 g·kg

-1

)

Tripterygium glucosides group(0.006 3 g·kg

-1

) were given corresponding drugs by gavage for three times a day

2 mL/time. The histopathology of rat ankle joint was observed

and the protein expressions of TARDD

IKK

NF-

B p65 in the NF-

B signaling pathway in synovial tissue of CFA rats were detected by Western blot.

Result:

With the increase of the dosage of XCHT

the histopathological score of the right posterior ankle joint of the experimental rats was increased. And in the protein expressions of TARDD

IKK

NF-

B p65 in NF-

B signaling pathway in Synovial Tissue of CFA rats

compared with the model group

the statistical results of the low-dose XCHT group showed decreased protein expressions (

0.05) and significant differences. However

the statistical results in the medium-dose XCHT group

the high-dose XCHT group and the tripterygium glucosides group showed decreased protein expression (

0.01) and significant differences. Compared with the normal group

the histopathological score of the right posterior ankle of the model group was significantly increased(

0.01)

and the protein expressions of TARDD

IKK

NF-

B p65 in the NF-

B signaling pathway were significantly increased (

0.01). Compared with model group

with the increase of dose of Xiao Chaihutang

histopathologic score of posterior ankle of experimental rats significantly reduced (

0.01). In rats ankle tissue samples

TARDD

IKK

NF-

B p65 key protein expressions in the NF-

B signaling pathway and protein expressions in low-dose XCHT group were obviously lower (

0.05)

and protein expressions in the medium-dose XCHT group

the high-dose XCHT group and the Tripterygium glucosides group were significantly lower (

0.01).

Conclusion:

This study shows that as the dose of Xiao Chaihutang increases

it could effectively improve synovitis

and suppress the expressions of key proteins in the inflammatory signaling pathway of NF-

thereby preventing inflammation and suppressing bone erosion.
