摘要:

电针刺激已被证实有缓解疼痛作用,但治疗臂丛神经损伤后疼痛的效果仍有待验证。实验设计了以电针刺激左侧全臂丛根性撕脱伤上肢慢性神经疼痛模型大鼠双侧曲池、合谷、足三里及阳陵泉的实验方案,发现电针治疗后,上肢慢性神经性疼痛大鼠疼痛明显减轻,且免疫荧光染色结果显示与疼痛相关的蛋白β-内啡肽在疼痛大鼠弓状核中的表达明显升高。证明电针能通过提高β-内啡肽的表达减轻臂丛神经损伤后的神经性疼痛。

Abstract:

Electroacupuncture has traditionally been used to treat pain, but its effect on pain following brachial plexus injury is still unknown. In this study, rat models of an avulsion injury to the left brachial plexus root (associated with upper-limb chronic neuropathic pain) were given electroacupuncture stimulation at bilateral Quchi (LI11), Hegu (LI04), Zusanli (ST36) and Yanglingquan (GB34). After electroacupuncture therapy, chronic neuropathic pain in the rats’ upper limbs was significantly attenuated. Immunofluorescence staining showed that the expression of β-endorphins in the arcuate nucleus was significantly increased after therapy. Thus, experimental findings indicate that electroacupuncture can attenuate neuropathic pain after brachial plexus injury through upregulating β-endorphin expression.
