摘要:


文题释义:

脾经合穴:即为阴陵泉穴,在古代文献记载与现代临床实践中均可用于治疗“筋伤”类疾病。且脾经气血在此汇合,使得阴陵泉穴本身具备“脾主肌肉四肢”与“脾主统血”的功效,对于四肢损伤具有较好疗效。
急性骨骼肌钝挫伤:指骨骼肌由一种非穿透性的、急剧的暴力损伤,使损伤部位肿胀、瘀血、肌纤维断裂,炎症反应现象明显,临床表现为疼痛、水肿以及活动受限。

背景:既往研究表明,推拿可促进骨骼肌损伤的修复,但其具体机制尚不明确。
目的:探讨点按脾经合穴对急性钝挫伤大鼠骨骼肌修复过程中炎症和钙离子稳态的影响。 
方法:将32只雄性SD大鼠随机分为空白组、模型组、点按非穴组、点按穴位组,除空白组外,其余3组均建立急性腓肠肌钝挫伤模型。点按非穴组取阴陵泉同一水平线与胆经和膀胱经中线的相交点穴;点按穴位组取“阴陵泉”穴,均1次/d,连续治疗7 d。干预结束后采用Catwalk小动物步态分析系统观察各组大鼠运动情况,苏木精-伊红染色法观察骨骼肌形态变化,ELISA法检测炎症因子水平和内质网钙ATP酶的活性,钙含量显色法检测骨骼肌组织钙浓度的变化,TUNEL法检测骨骼肌组织内细胞凋亡水平。
结果与结论:①与模型组比较,点按穴位组的平均支撑时相显著增大(P < 0.01);与点按非穴组比较,点按穴位组平均支撑时相显著增大(P < 0.05);②点按穴位组炎性细胞和红细胞聚集情况减少,且骨骼肌修复情况优于点按非穴组;③与模型组相比,点按穴位组肿瘤坏死因子α、白细胞介素6的质量浓度显著降低(P < 0.01),SERCA活性显著提高(P < 0.01);与点按非穴组比较,点按穴位组肿瘤坏死因子α质量浓度显著降低(P < 0.01),白细胞介素6的变化无显著差异(P > 0.05),SERCA的活性显著提高(P < 0.01);④与模型组比较,点按穴位组Ca2+浓度显著降低(P < 0.01);与点按非穴组相比,点按穴位组Ca2+的浓度显著降低(P < 0.05);⑤与模型组比较,点按非穴组与点按穴位组细胞凋亡率显著降低(P < 0.01);与点按非穴组比较,点按穴位组细胞凋亡率显著降低(P < 0.05);⑥提示点按脾经合穴可有效改善骨骼肌损伤大鼠运动功能,促进骨骼肌修复,其机制可能与降低炎症因子、促进钙泵功能、维持钙内环境稳态、从而减少细胞凋亡相关。

Abstract: BACKGROUND: Previous studies have shown that tuina can promote the repair of skeletal muscle injuries, but the specific mechanism is unclear.
OBJECTIVE: To investigate the effect of point-pressing of the spleen meridian on inflammation and calcium homeostasis in skeletal muscle repair in rats with acute blunt contusion injuries. 
METHODS: Thirty-two male Sprague-Dawley rats were randomly divided into blank group, model group, non-acupoint percussion group, and acupoint percussion group. Except for the blank group, animal models of acute gastrocnemius blunt contusion were established in the other three groups. In the non-acupoint pressing group, the intersection point of the same horizontal line of Yinlingquan acupoint (SP 9) and the midline of the gallbladder and bladder meridians was taken for percussion. In the acupoint pressing group, percussion was performed at the Yinlingquan acupoint. Point-pressing in the two groups was done once a day, for 7 consecutive days. Catwalk small animal gait analysis system was used to observe locomotor activity of rats. Hematoxylin-eosin staining was performed to observe the skeletal muscle morphology changes. ELISA method was used to detect the levels of inflammatory factors and the activity of sarcoplasmic/endoplasmic reticulum Ca2+ATPase (SERCA). Calcium concentration in the skeletal muscle was measured using the calcium assay. The level of apoptosis in the skeletal muscle was detected by TUNEL method.
RESULTS AND CONCLUSION: Compared with the model and non-acupoint pressing groups, the average support phase was significantly increased in the acupoint pressing group (P < 0.01, P < 0.05). Aggregation of inflammatory cells and red blood cells was reduced in the acupoint percussion group, and skeletal muscle repair was also better in the acupoint percussion group than the non-acupoint pressing group. Compared with the model group, the levels of tumor necrosis factor α and interleukin-6 were significantly decreased in the acupoint pressing group (P < 0.01), and the SERCA activity was significantly increased (P < 0.01). Compared with the non-acupoint pressing group, the level of tumor necrosis factor α was significantly decreased (P < 0.01), the level of interleukin-6 changed insignificantly (P > 0.05), and the activity of SERCA was significantly increased in the acupoint pressing group (P < 0.01). Compared with the model and non-acupoint pressing groups, the concentration of Ca2+ was significantly decreased in the acupoint pressing group (P < 0.01, P < 0.05). Compared with the model group, the apoptotic rate was significantly reduced in the two point-pressing groups (P < 0.01). The apoptotic rate in the acupoint percussion group was significantly lower than that in the non-acupoint pressing group (P < 0.05). To conclude, percussion of the spleen meridian can effectively improve the motor function of rats with skeletal muscle injury and promote skeletal muscle repair. Its mechanism may be related to reducing inflammatory factors, promoting calcium pump function, maintaining calcium homeostasis, and thereby reducing cell apoptosis.
