摘要:

文题释义:
推拿振法:推拿手法是指以治疗、保健为目的,用手或肢体其他部位,采用推、拿、按、揉、捏等技巧动作,在身体的特定部位或腧穴等位置进行操作的方法。操作振法时将手指或手掌着力在体表,前臂和手部的肌肉强力地静止性用力,产生振颤动作,具有祛瘀消积、缓解痉挛、和中理气及消食导滞等作用。
周围神经损伤:指周围神经干或其分支意外受到外界直接或间接创伤而发生的损伤,导致躯干和肢体的运动、感觉及自主神经功能出现障碍的一种临床病症,严重影响患者的生活质量。目前动物实验中关于周围神经损伤的研究常采用较为粗大且便于观察的坐骨神经。
背景:推拿振法治疗周围神经损伤疗效明确,但其作用机制的相关研究较少。
目的:探讨推拿振法对周围神经损伤后再生的作用机制。
方法:将28只SD大鼠随机分成假手术组(8只)和模型组(20只)。模型组大鼠给予坐骨神经钳夹损伤建立坐骨神经损伤模型,再随机取4只进行模型鉴定后,将剩余大鼠随机分为假干预组(8只)与推拿振法组(8只);假手术组仅开皮后缝合。分别于造模7 d后进行干预,推拿振法组用振动仪笔尖接触右下肢皮肤进行治疗,频率为8 Hz,1次/d,2 min/次,连续4周;假干预组振动仪仅接触皮肤,不给予推拿振法治疗;假手术组不做治疗。于干预后7,14,28 d行斜板试验及坐骨神经功能指数行为学指标检测,治疗28 d后取材行肌卫星细胞、胰岛素样生长因子1、MyoD生化指标检测。实验方案经上海中医药大学附属岳阳中西医结合医院动物实验伦理委员会批准。
结果与结论:①治疗7,14,28 d,假干预组和推拿振法组斜扳试验角度显著小于假手术组(均P < 0.05);假干预组与推拿振法组的斜板试验角度整体呈上升趋势,但两组之间差异不明显(P > 0.05);②治疗14,28 d推拿振法组坐骨神经功能指数明显优于假干预组;③治疗28 d后推拿振法组肌卫星细胞、胰岛素样生长因子1、Myod的吸光度值均显著高于假干预组,假干预组高于假手术组(均P < 0.05);④结果提示:推拿振法能促进大鼠运动功能的恢复,加速胰岛素样生长因子1、MyoD的表达及肌卫星细胞的增殖与分化,缓解骨骼肌肌萎缩状态,加速坐骨神经损伤后再生。

Abstract: BACKGROUND: Massage vibration therapy has definite effects on peripheral nerve injury. However, less is reported on its mechanism of action.
OBJECTIVE: To explore the mechanism of massage vibration on peripheral nerve regeneration after injury.
METHODS: Twenty-eight SD rats were randomly divided into sham operation group (n=8) and model group (n=20). Animal models of sciatic nerve injury were established in the model group by sciatic nerve clamping. Four rats in the model group were then randomly selected for model identification, and the remaining rats in the model group were randomly divided into sham intervention group (n=8) and massage vibration method group (n=8). In the sham operation group the skin was opened and sutured with no injury. The rats were intervened on the 7th day after modeling. In the massage vibration group, massage vibration was given using a vibrator by touching the skin of the right lower extremity at a frequency of 8 Hz, once a day, 2 min per time, for 4 consecutive weeks. In the sham intervention group, the vibrator only touched the skin but with no massage treatment. No treatment was given in the sham operation group. Incline plane test and behavioral indexes of sciatic function index were performed and measured after 7, 14, and 28 days of treatment, and muscle satellite cells, insulin-like growth factor 1, and MyoD biochemical index were detected after 28 days of  treatment. The study protocol was approved by the Animal Experiment Ethics Committee of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine.
RESULTS AND CONCLUSION: In the inclined plane test, the inclination angle of the sham intervention group and the massage vibration group was significantly smaller than that in the sham operation group after 7, 14, and 28 days of treatment (P < 0.05), but there was no significant difference between the sham intervention group and the massage vibration group (P > 0.05). The sciatic function index value in the massage vibration group was significantly better than that in the sham intervention group after 14 and 28 days of treatment. The positive expression of muscle satellite cells, insulin-like growth factor 1, and MyoD in the massage vibration group was highest after 28 days of treatment, followed by the sham intervention group and sham operation group (P < 0.05). To conclude, massage vibration method can effectively promote the recovery of motor function, accelerate the expression of insulin-like growth factor 1 and MyoD, expedite the proliferation and differentiation of muscle satellite cells, alleviate skeletal muscle atrophy, and accelerate sciatic nerve regeneration after injury.
