    摘要:

    目的] 观察关节内注射不同剂量河蚌葡聚糖 (anodonta glucan, HBP-A) 对豚鼠膝关节软骨退变及相关标志物的影响。[方法]豚鼠 20 只随机分为五组,分别为正常组、模型组、低浓度组、中浓度组和高浓度组,每组 4 只。正常组行右膝假手术处理,其余动物均行右膝前交叉韧带切断,建立骨性关节炎模型。术后 3 d,正常组和模型组右膝关节内注射生理盐水, 而低、中、高剂量组分别注射 7.5 mg/ml、15 mg/ml、30 mg/ml 的 HBP-A 200 μl,每周注射 1 次,连续 5 周。5 周后处死动物, 取右膝关节标本行组织学、免疫组织化学和 qPCR 检测。[结果]组织学观察见,与正常组相比,模型组出现显著软骨退变,而注射 HBP-A 组织结构显著改善。模型组较正常组 OARSI 评分显著增加(P<0.05),在给予低、中、高浓度 HBP-A 关节腔注射, OARS 评分呈剂量依赖性显著降低(P<0.05)。免疫组化方面,模型组较正常组软骨 ALP、Ihh、Runx2 和 MMP13 的 OD 值显著升高(P<0.05),而低、中、高浓度 HBP-A 关节注射软骨 ALP、Ihh、Runx2 和 MMP13 的 OD 值呈剂量依赖性显著降低(P<0.05)。 qPCR 检测表明,模型组较正常组软骨 IL-1β、Ihh、Runx2 和 MMP-13 的 mRNA 的相对表达量均显著增加 (P<0.05),在给予低、中、高浓度 HBP-A 关节腔注射,IL-1β、Ihh、Runx2 和 MMP-13 的 mRNA 的相对表达量均呈剂量依赖性显著降低 (P< 0.05)。[结论]关节腔内注射 HBP-A 能够减少或延缓豚鼠膝关节软骨退变程度。

    Abstract:

    [Objective] To explore the effects of intraarticular injection of anodonta glucan (HBP-A) in different dosages on cartilage de- generation of the knee, and related markers in guinea pigs. [Methods] Twenty guinea pigs were randomly divided into five groups, including the normal group, model group, low concentration group, medium concentration group and high concentration group, with 4 animals in each group. Four animals in the normal group were treated with right knee sham operation, while the remaining all animals were treated with ante- rior cruciate ligament transection of right knee to establish osteoarthritis (OA) model. Three days later, the normal group and model group were injected with normal saline into right knee joint, while the low, medium and high dose groups were injected with 7.5 mg/ml, 15 mg/ml and 30 mg/ml of HBP-A 200 μl, respectively, once a week for consecutive 5 weeks. Five weeks later, the animals were sacrificed, and the right knee samples were harvested for histological, immunohistochemical and qPCR assays. [Results] With histological observation, signifi- cant changes of cartilage degeneration were found in the model group compared with those in the normal group, whereas which significantly reversed in a dosage-dependent manner in the 3 groups with HBP-A in different dose. OARSI score in the model group was significantly higher than that of the normal group (P<0.05) , which significantly decreased in a dose-dependent manner in the 3 HBP-A groups (P<0.05) . In terms of immunohistochemistry, the optical density (OD) values of ALP, Ihh, Runx2 and MMP13 in the model group were significantly higher than those of the normal group (P<0.05) , whereas which declined significantly in the 3 HBP groups in the dose-dependent manner (P<0.05) . As results of qPCR assay, the mRNA relative expression levels of IL-1β, Ihh, Runx2 and MMP-13 in the model group were signif-icantly higher than those in the normal group (P<0.05) , which also reduced significantly after injection of low, medium and high concentra- tions of HBP-A into the joint cavity in the dose-dependent manner (P<0.05) . [Conclusion] In this study, intraarticular injection of HBP-A does reduce or delay the cartilage degeneration of the knee in guinea pigs.
