摘要:

临床上应用隔药灸可有效减轻炎症性肠病引起的内脏痛,但其镇痛机制仍无共识。有研究发现,细胞外信号调节激酶、P物质和神经激肽1能共同引起疼痛信号的转导,因此作者推测隔药灸镇痛效应可能与上述因子有关。为验证此假设,实验设计以5%三硝基苯磺酸和50%乙醇混合溶液灌肠建立炎症性肠病内脏疼痛大鼠模型,在双侧天枢(ST25)和气海(CV6)进行隔药灸约10min,1次/d,连续7d。结果显示,隔药灸能明显减轻大鼠的内脏疼痛,并降低背根神经节中细胞外信号调节激酶、P物质和神经激肽1蛋白及mRNA的表达,说明隔药灸抑制细胞外信号调节激酶、P物质和神经激肽1表达,是其发挥肠性镇痛作用的分子机制之一。

Abstract:

Herb-partitioned moxibustion can effectively mitigate visceral pain, a major symptom in inflammatory bowel disease, but the analgesic mechanism is still unclear. Moreover, extracellular signal-regulated kinase, substance P, and neurokinin-1 are involved in formation of central hyperalgesia. Thus, we postulated that the analgesic effect of herb-partitioned moxibustion may be associated with these factors.Accordingly, in this study, we established an inflammatory bowel disease visceral pain model in rat by enema with a mixed solution of 5% trinitrobenzenesulfonic acid and 50% ethanol. Bilateral Tianshu (ST25) and Qihai (CV6) points were selected for herb-partitioned moxibustion.Our results showed that herb-partitioned moxibustion improved visceral pain and down-regulated extracellular signal-regulated kinase, substance P, and neurokinin-1 protein and mRNA expression in dorsal root ganglia. These results indicate that down-regulation of extracellular signal-regulated kinase, substance P, and neurokinin-1 protein and mRNA may be a central mechanism for the analgesic effect of herb-partitioned moxibustion.
