摘要

目的观察复元胶囊(Fuyuan capsule，Fyc)对实验性兔膝骨关节炎（osteoarthritis，OA）软骨中尿激酶型纤溶酶原激活物(urokinase-type plasminogen activator，uPA)、uPA受体(uPA receptor，uPAR)、血浆酶原激活酶抑制因子(plasminogen activator inhibitor，PAI)的影响

探讨其对实验性兔膝OA的作用机制。方法采用膝关节石膏制动法结合d-半乳糖皮下注射6周建立兔衰老骨关节炎模型。48只新西兰兔根据体质量按随机区组法分为健康组、模型组、盐酸氨基葡萄糖胶囊90 mg/（kg·d）组，复元胶囊低、中、高剂量组[1 350、2 700、5 400 mg/（kg·d）

]

，每组8只，造模当日开始灌胃，1次/d，连续10 周。HE染色关节软骨Mankin’s评分，免疫组织化学法检测各组软骨组织中uPA、uPAR、PAI的表达，Western blot检测各组软骨组织中uPA、NF-κB的表达。结果复元胶囊高剂量组和盐酸氨基葡萄糖胶囊组的兔OA关节软骨Mankin’s评分较模型组明显降低（

0.01）；免疫组化检测结果显示，复元胶囊高剂量组和盐酸氨基葡萄糖胶囊组uPA及uPAR表达明显降低，而PAI表达明显升高（

0.01）；Western blot检测结果显示，盐酸氨基葡萄糖胶囊组和复元胶囊高剂量组uPA及NF-κB均较模型组显著降低（

0.01）。复元胶囊高剂量组对uPA的抑制作用与盐酸氨基酸葡萄糖胶囊组比较差异无统计学意义（

>0.05），但对NF-κB的抑制作用强于盐酸氨基酸葡萄糖胶囊组（

0.05）。结论复元胶囊能显著降低兔关节软骨中uPA、uPAR、NF-κB的表达，明显升高PAI的表达，提示复元胶囊可能通过调控uPA系统和NF-κB信号通路对骨关节炎发挥防治作用。

Abstract

Objective To determine the efficiency of Fuyuan capsule (Fyc

a capsule containing several Chinese herbs) on the expression

of urokinase-type plasminogen activator (uPA)

uPA receptor (uPAR)

plasminogen activator inhibitor (PAI) and NF-κB in the cartilage tissues of experimental osteoarthritis (OA) rabbits. Methods A total of 48 New Zealand rabbits were divided into 6 groups randomly with 8 rabbits in each group: normal group

model group

glucosamine hydrochloride capsule group [90 mg/(kg·d)

]

and low-

middle- and high-dose Fyc capsule groups [1 350

2 700 and 5 400 mg/(kg·d)

]

. The rabbits of model and treatment groups were inflicted by combined injection of D-galactose and plaster immobilization into their left knee joint to produce osteoarthritis model. All drugs were given from the same day of modeling

by gavage injection

daily

for 10 weeks. Mankin’s score was detected by light microscopy and HE staining. Then cartilage sections were analyzed by immunohistochemistry for uPA

uPAR and PAI. The protein expressions of uPA and NF-κB were detected by Western blotting. Results After treatment with high-dose Fyc and glucosamine hydrochloride capsule

the Mankin’s score was decreased significantly when compared with model group (3.28±0.46 and 3.46±0.78

8.73±0.94

0.01). Immunohistochemical staining indicated that the expression intensities and positive cell ratio of uPA and uPAR were decreased and those of PAI were increased

and Western blotting showed that the protein expressions of uPA and NF-κB were reduced significantly in high-dose Fyc and glucosamine hydrochloride capsule groups. Compared to the model group

all these difference were significantly (

0.01). But there was no significant difference in the inhibiting effect to uPA in the high-dose Fyc and glucosamine hydrochloride groups (

>0.05)

but the former group showed stronger effect on NF-κB reduction (

0.05). Conclusion Fyc capsule downregulates uPA

uPAR and NF-κB

while upregulate PAI in the cartilage tissues of experimental osteoarthritis rabbits

which suggests the capsule

may exert its effect through regulating the uPA system and NF-κB signaling pathway.
