摘要:

文题释义:
超声乳化:在局部麻醉的情况,通过常规超声影像辨别病变组织并引导超声吸引手术系统经皮对软组织病变进行灌注、碎解乳化、吸引清除等操作,从而达到消除病变、恢复系统正常生理功能的目的。
跟腱炎:一般指跟腱因过度活动、损伤或摩擦等急慢性劳损后形成的无菌性炎症。

背景:肌腱炎目前保守治疗和手术治疗都难以达到治愈效果,临床尚未有可广泛应用的微创便捷的治疗手段。
目的:通过建立跟腱炎兔模型探究应用超声乳化仪治疗跟腱炎的可行性。
方法:使用胶原酶注射法构建新西兰白兔右下肢跟腱炎模型,将30只新西兰白兔随机分为3组:对照组注射生理盐水,不治疗;模型组注射胶原酶造模,不治疗;治疗组注射胶原酶造模,造模后3周应用超声引导下的超声乳化法治疗跟腱炎病灶。治疗后3周取3组兔的跟腱组织进行生物力学测试、测定组织羟脯氨酸含量及苏木精-伊红染色观察跟腱修复情况。
结果与结论:经超声乳化治疗3周后,苏木精-伊红染色显示治疗组胶原纤维杂乱排列及细胞聚集的情况较模型组有所改善,但生物力学分析及羟脯氨酸含量测定无明显改善。说明超声乳化在治疗肌腱炎方面具有应用前景,但还需对治疗参数和模式进一步探索与优化以多方面提高应用效果。

Abstract: BACKGROUND: At present, conservative and surgical treatments are difficult to cure tendinitis. A minimally invasive and convenient treatment has not been widely used in clinical practice.
OBJECTIVE: To explore the feasibility of applying ultrasonic emulsification device to treat Achilles tendinitis in a rabbit model of Achilles tendinitis.
METHODS: Thirty New Zealand rabbits were randomized into a control group, a model group and an ultrasonic emulsification group. A model of Achilles tendinitis was built in the model and ultrasonic emulsification groups by collagenase injection. Rabbits in the control and model groups were only given normal saline, while those in the ultrasonic emulsification group were subjected to ultrasonic emulsification under guidance of B-mode ultrasonic scan within at 3 weeks after modeling. Three weeks after treatment, tendon repair was estimated by biomechanical analysis, hydroxyproline concentration measurement, and hematoxylin-eosin staining of the tendon tissue.
RESULTS AND CONCLUSION: Three weeks after ultrasonic emulsification treatment, hematoxylin-eosin staining showed that the disordered arrangement of collagen fibers and the cell condensation were improved compared with the model group, while the biomechanical analysis and hydroxyproline concentration showed no relief in tendinitis. Therefore, ultrasonic emulsification treatment has an application prospect in tendon repair; however, it is necessary to further explore and optimize the treatment parameters and modes to improve the therapeutic effect in many aspects.
