摘要:

目的 研究消瘀散新组方对膝骨关节炎(knee osteoarthritis,KOA)兔关节软骨的作用及机制。 方法 将42只6月龄普通级新西兰白兔随机分为正常组、模型组、消瘀散组、消瘀散新组方组,每组10只(另2只用于模型验证)。除正常组外,其他各组兔均按照改良Hulth法对右侧膝关节进行KOA造模。造模5周后,对消瘀散组、消瘀散新组方组动物分别给予相应的贴膏进行膝关节炎治疗,每天1次,每次持续10 h。连续给药治疗2周后,取4组兔膝关节软骨,行大体观察并采用Outerbridge分级法评价各组软骨损伤情况,采用HE染色法在光学显微镜下观察各组兔膝关节软骨、钙化层和软骨下骨病理改变,并采用Mankin's法评价软骨退变程度,采用免疫组织化学法在光学显微镜下观察各组兔膝关节软骨组织中基质金属蛋白酶13(matrix metalloproteinase- 13,MMP-13)的表达情况。 结果 关节软骨大体观察后Outerbridge评级比较发现,消瘀散组较模型组的高分级动物数减少(P<0.05),消瘀散新组方组比消瘀散组的高分级动物数也减少(P<0.05)。HE染色发现4组兔关节软骨的Mankin's评分由高到低依次为模型组(10.82±1.76)、消瘀散组(6.19±1.23)、消瘀散新组方组(2.64±1.18)和对照组(0.28±0.17),各组间差异有统计学意义(P<0.05)。免疫组织化学检测发现各组兔关节软骨组织中MMP-13表达阳性率由高到低依次为模型组(67.90±13.94)%、消瘀散组(37.10±19.16)%、消瘀散新组方组(13.60±3.10)%和对照组(3.20±2.39)%,各组间差异有统计学意义(P<0.05)。 结论 消瘀散新组方可修复KOA兔关节软骨损伤,降低软骨组织中MMP-13的表达水平,这可能是其治疗骨关节炎的作用机制之一。

Abstract:

Objective To study the effect of Xiaoyusan new formula on the articular cartilage of knee osteoarthritis (KOA) rabbits and its mechanism. Methods A total of 42 New Zealand white rabbits aged 6 months were randomly divided into normal group, model group, ointment of Xiaoyusan group, and ointment of Xiaoyusan new formula group, with 10 rabbits in each group (the other 2 rabbits were used for model validation). Except for the normal group, the right knee joints of all rabbits in the other groups were prepared as KOA models according to the modified Hulth method. After 5 weeks of molding, the rabbits in ointment of Xiaoyusan group, ointment of Xiaoyusan New Formula group were given corresponding ointments for knee arthritis treatment, once a day, each time for 10 hours. After 2-week continuous administration and treatment, the knee joint cartilage of the four groups of rabbits was taken and the cartilage damage of each group was evaluated by Outerbridge grading method. The pathological changes of the cartilage, calcified layer and subchondral bone of the knee joint of rabbits in each group were observed by HE staining method under the light microscope, and the degree of cartilage degeneration was evaluated by Mankin's method. The expression of matrix metalloproteinase-13 (MMP-13) in the cartilage of rabbit knee joint in each group was deteced by immunohistochemistry. Results After the general observation of articular cartilage, the Outerbridge grading showed that the number of high-grade animals in ointment of Xiaoyusan group was reduced compared with the model group (P<0.05), and the number of high-grade animals in ointment of Xiaoyusan new formula group was also reduced (P<0.05) compared with ointment of Xiaoyusan group. HE staining showed that Mankin's scores of articular cartilage in the four groups ranked from high to low: model group (10.82±1.76), ointment of Xiaoyusan group (6.19±1.23), ointment of Xiaoyusan new formula group (2.64±1.18) and normal group (0.28±0.17). The difference among four groups was statistically significant (P<0.05). Immunohistochemical detection showed that the positive rates of MMP-13 expression in rabbit articular cartilage tissues in each group were (67.90±13.94)% of model group, (37.10±19.16)% of ointment of Xiaoyusan group, (13.60±3.10)% of ointment of Xiaoyusan new formula group and (3.20±2.39) % of normal group, ranking from high to low, and the difference among four groups was statistically significant (P<0.05). Conclusion Xiaoyusan new formula can repair articular cartilage degeneration in KOA rabbits and decrease the expression of MMP-13 in cartilage, which may be one of the mechanisms of the treatment.
