摘要:

文题释义:
川续断皂苷VI:是川续断中一种极具药用价值的三菇皂苷类化合物,具有神经保护、心肌保护、抗骨质疏松、保肝降脂等生物学作用,尤其抗骨质疏松作用较好,与功效中的补肝肾、强筋骨、续折伤相吻合。
肌腱病:肌腱损伤是骨科常见的疾病,全球每年有上千万例新诊断的肌腱损伤患者,主要由于肌腱长期过度使用导致肌腱的退行性改变所致。目前肌腱病的病因病理机制尚未定论,仍缺少有效的肌腱病治疗手段,在分子水平上研究肌腱病有助于开发新的治疗策略。
背景:近年来肌腱病是一种高发的骨科慢性损伤,目前仍缺少有效的治疗手段,川续断具有补肝肾、强筋骨、续折伤等功效。
目的:旨在研究川续断中主要成分川续断皂苷VI对兔肌腱病的修复作用。
方法:48只兔随机分为正常组(n=8)、模型组(n=32)和生理盐水组(n=8),其中模型组于左跟骨附着点注射前列腺素E2建立兔跟腱病模型,随后随机分为4个亚组,分别采用0,10,20,40 mg/kg川续断皂苷VI治疗,1次/d,连续4周。动物实验于2019-11-04经成都体育学院动物伦理委员会批准,批准号:成体伦理[2020]21号。
结果与结论:①与正常组相比,模型组基质金属蛋白酶1表达水平较高;而与模型组相比,川续断皂苷VI中、高剂量组基质金属蛋白酶1表达下调(P < 0.05);模型组金属蛋白酶抑制剂1水平高于正常组,而在川续断皂苷VI低、中、高剂量组均可降低金属蛋白酶抑制剂1的表达水平(P < 0.05);与模型组相比,川续断皂苷VI低、中、高剂量转化生长因子β1表达水平上调(P < 0.05);与模型组相比,川续断皂苷VI高剂量纤溶酶原激活物抑制剂1表达水平升高(P < 0.05);②川续断皂苷VI高剂量组纤维组织排列及分布恢复均接近正常肌腱组织。提示川续断皂苷VI可平衡细胞外基质胶原异常代谢,诱导肌腱细胞增殖,利于保持肌腱胶原的稳定性促进愈合,可能是一种潜在的治疗肌腱病的药物。

Abstract: BACKGROUND: In recent years, tendonopathy occurs frequently as a chronic orthopedic injury, and there is still a lack of effective treatment as yet. Dipsacus L. has the effect of tonifying the liver and kidney, strengthening bones, and sustaining broken injuries.
OBJECTIVE: To analyze the repairing effect of Asperosaponin VI in a rabbit model of Achilles tendinopathy.
METHODS: Forty-eight rabbits were randomized into a normal control group (n=8), a model group (n=32), and a noral saline group (n=8). In the model group, the model of tendinopathy was made at the left calcaneus attachment injected with prostaglandin E2, and the models were then randomized into four subgroups, which were treated with 0, 10, 20, and 40 mg/kg Asperosaponin VI, respectively. Treatments in each group were conducted once a day for 4 consecutive weeks. The study protocol was approved by the Animal Ethics Committee of Chengdu Sport University with an approval No. [2020]21 on November 4, 2019. 
RESULTS AND CONCLUSION: Compared with the normal control group, the expression of matrix metalloproteinase-1 was significantly higher in the model group (P < 0.05). Compared with the model group, the expression of matrix metalloproteinase-1 was significantly reduced in the 20 and 40 mg/kg groups (P < 0.05). The expression of tissue inhibitor of matrix metalloproteinases 1 was significantly higher in the model group than the normal control group (P < 0.05), while the expression of tissue inhibitor of matrix metalloproteinases 1 was significantly reduced in the 10, 20 and 40 mg/kg groups compared with the model group (P < 0.05). The expression of transforming growth factor-β1 was significantly higher in the 10, 20 and 40 mg/kg groups compared with the model group (P < 0.05). The expression of plasminogen activator inhibitor 1 was significantly higher in the 40 mg/kg group than the model group (P < 0.05). Tendon fibers in the 40 mg/kg group were intact and arranged orderly, which were similar to normal tendon tissue. Therefore, Asperosaponin VI can inhibit vicious cycle of degeneration of collagen in the extracellular matrix, induce the proliferation of tenocytes and promote the healing. It may be a potential drug for the treatment of tendinopathy.

Key words: Asperosaponin VI, tendinopathy, healing, collagen, extracellular matrix, tenocyte, proliferation, fibrosis
