推拿通过NF-κB/GT通路对minor CCI大鼠的镇痛启动机制研究OACSTPCD
Explore the analgesic initiation mechanism of tuina in minor CCI rats with NF-κB/GT pathway as the main pathway
目的:探讨推拿治疗神经病理性疼痛的镇痛启动机制.方法:将 32 只雄性大鼠随机分为假手术组、模型组、推拿组和推拿+PDTC组,模型组、推拿组和推拿+PDTC组建立 minor CCI模型.造模后 7d推拿组进行三法三穴干预 1 次.通过 Von Frey法检测大鼠的机械疼痛和热痛阈值,双重免疫荧光标记法、Western blot和 RT-PCR技术检测大鼠 SDH 中 NF-κB/GT 通路相关分子变化.结果:推拿干预 1 次后,与模型组相比,推拿组和推拿+PDTC组的 MWT和TWL值、EAAT2 细胞数目、蛋白及 mRNA表达显著升高(均P<0.05),GFAP 细胞数目、蛋白、mRNA表达和 NF-κB mRNA表达显著降低(均 P<0.05);与推拿组相比,推拿+PDTC 组的 MWT 和 TWL值、EAAT2 细胞数目、蛋白及 mRNA表达升高(均P<0.05),GFAP细胞数目、蛋白、mRNA表达和 NF-κB mRNA表达降低(均P<0.05).结论:推拿可通过调节 NF-κB/GT信号通路发挥即刻镇痛作用.
Objective:To investigate how tuina helps to start pain relief in treating neuropathic pain.Methods:32 male rats were randomly assigned to four groups:sham group,model group,tuina group,and tuina+PDTC group.A minor CCI model was created in the model group,tuina group,and tuina+PDTC group.Seven days after modeling,the tuina group and tuina+PDTC group received treatment using three methods and three points once.The mechani-cal and thermal pain thresholds of the rats were measured using the Von Frey method,and molecular changes related to the NF-κB/GT pathway in the rat SDH were analyzed through dual immunofluorescence labeling,Western blot,and RT-PCR.Results:After one treatment,the MWT and TWL values,EAAT2 cell number,protein,and mRNA ex-pression were significantly higher in the tuina group and tuina+PDTC group compared to the model group(all P<0.05).Conversely,the GFAP cell number,protein,mRNA expression,and NF-κB mRNA expression were signifi-cantly lower(all P<0.05).Compared with the tuina group,the MWT and TWL values,the number of EAAT2 cells,protein and mRNA expression in the tuina+PDTC group were increased(all P<0.05),GFAP cell number,protein,mRNA expression and NF-κB mRNA expression were decreased(all P<0.05).Conclusion:Tuina can pro-vide immediate pain relief by controlling the NF-κB/GT signaling pathway.
