Previous studies have proved and investigated the mechanism of the analgesic effect of tuina treatment on neuropathic pain. The purpose of this study was to analyze changes in gene expression in the dorsal root ganglia (DRG) and spinal dorsal horn (SDH) after 1-time tuina intervention to investigate the immediate analgesic mechanism by tuina. An improvement in nociceptive behavior in minor chronic constriction injury (CCI) rats after 1-time tuina was observed. 1-time tuina was more effective in the amelioration of thermal hyperalgesia, but no changes were found in the ultrastructure of DRG and SDH. Sixty-five differentially expressed genes (DEGs) modulated by tuina were detected in the DRG and 123 DEGs were detected in the SDH. Potential immediate analgesic mechanisms of tuina were analyzed by the Kyoto Encyclopedia of Genes and Genomes. DEGs were enriched in 75 pathways in DRG, and 107 pathways in SDH. The immediate analgesic mechanism of tuina is related to the calcium signaling pathway, thermogenesis, and regulation of lipolysis in adipocytes.
以往的研究已经证实并探讨了推拿治疗神经性疼痛的镇痛作用机制。本研究的目的是分析单次推拿干预后背根神经节(DRG)和脊髓背角(SDH)中基因表达的变化,以探讨推拿的即时镇痛机制。观察到单次推拿后轻微慢性压迫损伤(CCI)大鼠的伤害性感受行为有所改善。单次推拿在改善热痛觉过敏方面更有效,但DRG和SDH的超微结构未发现变化。在DRG中检测到65个受推拿调节的差异表达基因(DEG),在SDH中检测到123个DEG。通过京都基因与基因组百科全书分析了推拿潜在的即时镇痛机制。DEG在DRG中富集于75条通路,在SDH中富集于107条通路。推拿的即时镇痛机制与钙信号通路、产热以及脂肪细胞中脂肪分解的调节有关。
