针刺治疗脊髓损伤细胞信号转导机制的研究与思考

Reviews on acupuncture for cellular signal transduction in spinal cord injury

研究针刺对细胞信号转导的影响,是揭示针刺治疗脊髓损伤(SCI)作用机制的有效途径。笔者通过回顾和分析近10年来针刺治疗SCI的实验研究文献,发现针刺可通过调节胞间第一信使和环磷酸腺苷、环磷酸鸟苷、Ca^(2+)及一氧化氮等胞内第二信号分子的表达,干预细胞凋亡信号通路、Rho/Rock信号通路、Wnt信号通路、MAPK信号通路及Notch信号通路等信号途径而发挥促进SCI再生修复的效应,认为今后的研究应重视细胞信号转导立体网络的探索,并注意研究不同配穴、刺激方法等对细胞信号转导影响的差异,这对揭示针刺的临床应用规律,优化临床治疗方案具有重要意义。

Investigating the influence of acupuncture on cellular signal transduction is an efficient pathway to reveal the action mechanism of acupuncture on spinal cord injury（SCI）. In this study, the experiment research literature regarding acupuncture for SCI during past 10 years was reviewed and analyzed. As a result, it was found that acupuncture could regulate the expression of the first intercellular messenger as well as the second signal molecules including cyclic adenosine monophosphate, cyclic guanosine monophosphate, Ca2＋, nitric oxide to intervene the apoptotic signaling pathway, Rho/Rock signaling pathway, Wnt signaling pathway, MAPK signaling pathway, Notch signaling pathway, etc., which could improve regeneration and repair of SCI. In conclusion, in future researches more attention should be paid to the cellular signal transduction networks and different effects among various acupoint combinations and acupuncture modalities on cellular signal transduction, which have an essential role for revelation of clinical application rules and optimization of clinical treatment protocol.
