针刺对大鼠骨骼肌挫伤后肌肉再生的影响

The Impact of Acupuncture on Muscle Regeneration in Rat Skeletal Muscle Contusion

目的:观察针刺对SD大鼠骨骼肌钝挫伤后肌肉再生的影响。方法:将采用打击装置造成后下肢腓肠肌钝挫伤的大鼠随机分为即刻组、针刺治疗组、自然愈合组。针刺治疗组采用阿是穴针刺疗法,自然愈合组不治疗。结果:针刺能促使炎症反应早期出现和及时消退,从而加速坏死组织的清除,并更好地激活肌肉再生过程。大鼠骨骼肌挫伤后,针刺能促进肌卫星细胞的增殖并促使活跃期提前出现,促进肌肉再生。结论:针刺能促进大鼠急性骨骼肌钝挫伤后肌肉再生,加速组织愈合的进程并提高愈合质量。

Objective： The purpose is to observe the effect of acupuncture on muscle regeneration after SD rat skele- tal muscle contusion. Method： In this research, the device was used to combat the rat＇s lower limb gastrocnemius after muscle contusion. And the rats were divided into blunt immediate group,acupuncture group and the natural healing group. The treatment group was treated with Ashi point acupuncture therapy. Result： The results showed that acupuncture could induce inflammatory reaction occurs early and timely dissipated, thereby accelerat- ed the removal of necrotic tissue,and had a better activation of muscle regeneration process. After the damage of the rat＇s skeletal muscle, acupuncture could promote muscle satellite cell proliferation and induce active early e- mergence, contribute to muscle regeneration. Conclusion： acupuncture could promote muscle regeneration after the rat acute skeletal muscle contusion, accelerate tissue healing process and improve the healing quality.
