摘要： 目的 探讨电针治疗腓肠肌损伤的可能机制。方法 30只雄性 Sprague-Dawley大鼠随机分为空白组(n=10)、模型组(n=10)和电针组(n=10)。模型组和电针组采用腓肠肌钝挫伤的方法制备模型，电针组电针三阴交、阴陵泉穴14 d。治疗结束后取腓肠肌组织行HE染色，免疫组化法检测大鼠腓肠肌组织、ELISA法检测大鼠血清碱性成纤维细胞生长因子(bFGF)和胰岛素样生长因子-1 (IGF-1)的表达。结果 与模型组相比，电针组损伤程度较轻，腓肠肌组织 bFGF、IGF-1表达明显升高(P<0.01)，血清含量升高(P<0.05)。结论 电针可以促进腓肠肌损伤大鼠损伤后修复，其机制可能与上调修复因子bFGF和IGF-1的表达水平有关。

Abstract: Objective To investigate the effects of electroacupuncture at Sanyinjiao (SP6) and Yinlingquan (SP9) on muscle repair in the gastrocnemius muscle damaged rats and its possible mechanism. Methods 30 male Sprague-Dawley rats were randomly divided into blank group (n=10), model group (n=10) and electroacupuncture group (n=10). The latter 2 groups were modeled with gastrocnemius muscle crush injury. The electroacupuncture group received electroacupuncture at Sanyinjiao and Yinlingquan for 14 days. Their gastrocnemius was observed with HE staining, and the expressions of basic fibroblast growth factor (bFGF) and insulin-like growth factor-1 (IGF-1) in gastrocnemius tissues and the serum were determined with immunochemical assay and enzyme- linked immunosorbent assay (ELISA). Results Compared with the model group, there was less damage in the electroacupuncture group, with more expression of bFGF and IGF-1 in tissues (P<0.01) and serum (P<0.05). Conclusion Electroacupuncture can promote muscle repair after gastrocnemius muscle damage in rats, which may be related to the increase of the bFGF and IGF-1 expression in gastrocnemius tissue and serum.
