摘要:

背景:膝骨关节炎的病理学改变不可逆转,属中医“痹证”范畴,治疗目的是缓解或解除症状,延缓关节退变。健膝强骨丸方是武汉大学基础医学院荆州市第三人民医院的经验方,可补益肝肾,祛风散寒,除湿通络,强骨健膝。
目的:观察健膝强骨丸对膝骨关节炎兔模型膝骨关节软骨的保护作用,及其对软骨细胞骨形态发生蛋白7表达的影响。
方法:36只新西兰兔随机分为3组,每组12只,分别运用改良Hulth术制备兔膝骨关节炎模型。造模后第6周,给药组予健膝强骨丸0.1 g/kg灌胃,模型组和正常对照组予等量生理盐水灌胃。给药4周后通过软骨Mankin’s评分方法行兔膝关节软骨评分,电镜下观察软骨形态,免疫组化法检测膝关节软骨细胞骨形态发生蛋白7表达情况。
结果与结论:给药组兔膝关节软骨病理退变程度较其他2组轻,膝关节软骨细胞骨形态发生蛋白7的表达量较其他2组高,差异有显著性意义(P < 0.05)。提示健膝强骨丸可增强膝骨关节炎模型兔关节软骨细胞骨形态发生蛋白7的表达,从而促进膝关节软骨再生,减少软骨变形坏死,达到治疗关节炎的目的。

Abstract:

BACKGROUND: Knee osteoarthritis is characterized by inreversible pathological changes, belonging to arthragia syndrome. The goal of the treatment is to release or relieve symptoms and delay joint degeneration. Jianxi Qianggu Pill is an empirical formula developed by the Third People’s Hospital of Jingzhou, School of Basic Medical Science, Wuhan University, China. This prescription can nourish liver and kidney, eliminate wind and disperse cold, expel wet and dredge the collaterals, consolidate bone and reinforce knee. 

OBJECTIVE: To observe the protective effect of Jianxi Qianggu Pill on joint cartilage and expression of bone morphogenetic protein 7 in rabbits with knee osteoarthritis.
METHODS: A total of 36 New Zealand rabbits were randomly divided into three groups, with 12 ones in each. The involved rabbits were applied to establish the model of knee osteoarthritis by using the modified Hulth’s method. At 6 weeks after modeling, the drug group was given 0.1 g/kg Jianxi Qianggu Pill via intragastric administration, while model group and normal control group received equal volume of saline. At 4 weeks after drug administration, rabbit articular cartilage was evaluated with Mankin’s scoring method. The cartilage morphology was observed under electron microscopy, and bone morphogenetic protein 7 expression was detected using immunohistochemistry.
RESULTS AND CONCLUSION: The pathological degeneration degree of articular cartilage in the drug group was significantly lighter, and bone morphogenetic protein 7 expression was significantly higher than the other two groups (P < 0.05). Experimental findings indicate that, Jianxi Qianggu Pill can promote the expression of bone morphogenetic protein 7 in articular cartilage of knee osteoarthritis rabbits, thereby promoting articular cartilage regeneration and reducing cartilage deformation or necrosis for the treatment of arthritis.
