摘要:
目的:探讨柚皮苷降低关节液基质金属蛋白酶-13(MMP-13)、多配体蛋白聚糖-4(Syndecan-4)浓度修复兔膝关节软骨损伤的作用。方法:将16只大耳白兔随机分为假手术组、模型组、柚皮苷组、阳性对照组,每组4只。关节软骨损伤造模后,模型组给予去离子水灌胃,柚皮苷组给予柚皮苷灌胃,阳性对照组给予硫酸氨基葡萄糖灌胃。于第12周采用酶联免疫吸附测定(ELISA)法检测关节液MMP-13、Syndecan-4浓度水平,显微CT(Micro-CT)观察关节软骨损伤结构修复,免疫组化法检测关节软骨损伤处P-Smad2表达水平。结果:与假手术组相比,模型组关节液MMP-13、Syndecan-4浓度显著升高(P<0.05),可见明显关节软骨损伤缺损表现,软骨损伤处骨体积分数、骨小梁分离度、骨小梁厚度参数明显不佳(P<0.05)。与模型组相比,柚皮苷组与阳性对照组关节液MMP-13、Syndecan-4浓度显著下降(P<0.05)。与模型组相比,柚皮苷组关节面出现明显修复表现,柚皮苷组关节软骨损伤处骨体积分数、骨小梁分离度、骨小梁厚度参数明显好转(P<0.05)。与模型组相比,柚皮苷组P-Smad2表达水平明显上升。结论:骨碎补主要活性成分柚皮苷可降低关节液MMP-13、Syndecan-4的浓度水平,改善兔膝关节软骨损伤结构,提高关节软骨损伤的修复水平,其可能的机制与激活TGF-β/Smad信号通路的表达水平密切相关。药证相应,TGF-β/Smad信号通路受到抑制引起炎症水平增强所致的关节软骨损伤可能是膝骨关节炎肝肾亏虚的证候特点之一。
Abstract:
Objective:To investigate the effect of naringin on the repair of knee cartilage injury by reducing the concentration of matrix metalloproteinase-13(MMP-13)and Syndecan-4 in synovial fluid.Methods:16 large-eared white rabbits were randomly divided into four groups:sham surgery group,model group,naringin group,and positive control group,with 4 rabbits in each group.After the establishment of the articular cartilage injury model,the model group was given deionized water for gastric lavage,the naringin group was given naringin for gastric lavage,and the positive control group was given glucosamine sulfate for gastric lavage.At the 12th week,the levels of MMP-13 and Syndecan-4 in the synovial fluid were detected using the enzyme-linked immunosorbent assay(ELISA)method,the repair of articular cartilage injury structure was observed by Micro-CT,and the expression level of P-Smad2 at the site of articular cartilage injury was detected by immunohistochemical method.Results:Compared with the sham surgery group,the concentrations of MMP-13 and Syndecan-4 in the synovial fluid in the model group were significantly increased(P<0.05),indicating obvious articular cartilage injury and defect,bone volume fraction,trabecular separation and trabecular thickness at the site of cartilage injury were significantly lower(P<0.05).Compared with model group,the concentrations of MMP-13 and Syndecan-4 in synovial fluid of naringin group and positive control group were significantly decreased(P<0.05).Compared with model group,naringin group showed obvious repair performance of articular surface,and naringin group significantly improved bone volume fraction,trabecular separation and trabecular thickness at articular cartilage injury(P<0.05).Compared with the model group,the expression level of P-Smad2 in naringin group was significantly increased.Conclusion:The main active ingredient of rhizoma drynariae,naringin,can reduce the concentration levels of MMP-13 and Syndecan-4 in synovial fluid,improve the structure of articular cartilage injury in rabbit knee joints,and enhance the repair level of articular cartilage injury.Its possible mechanism is closely related to the activation of the expression levels of the TGF-β/Smad signaling pathway.Correspondingly,the inhibition of the TGF-β/Smad signaling pathway,which leads to an increase in inflammatory levels and causes articular cartilage injury,may be one of the characteristics of knee osteoarthritis with liver and kidney deficiency.
