Objective： To observe the effect of moxibustion on the protein and mRNA expressions of corticotropin-releasing factor （CRF） and corticotropin-releasing factor receptor 2 （CRFR1） in hypothalamus of trinitrobenzene...Objective： To observe the effect of moxibustion on the protein and mRNA expressions of corticotropin-releasing factor （CRF） and corticotropin-releasing factor receptor 2 （CRFR1） in hypothalamus of trinitrobenzene sulfonic acid （TNBS）-induced experimental colitis rats, and to explore the central mechanisms of moxibustion in improving visceral pain and the pain-related emotions in experimental colitis rats. Methods： Thirty-six Sprague-Dawley （SD） rats were randomly divided into a normal group （NG）, a model group （MG）, a herb-partitioned moxibustion group （HPMG） and a sham herb-partitioned moxibustion group （SHPMG）. Except the NG, rats in the remaining three groups all received TNBS enema to establish experimental colitis models. The HPMG received herb-partitioned moxibustion （HPM） at bilateral Tianshu （ST 25） and Qihai （CV 6） for intervention; for the SHPMG, the herbal cakes and moxa cones were only placed on the acupoints but not ignited; rats in the MG and NG were only fixed in the same way as those in the HPMG but did not receive any treatment. At the end of the intervention, the abdominal withdrawal reflex （AWR） score, the open field test （OFT） score and the elevated plus maze （EPM） score were observed to measure the changes in visceral pain and pain-related emotions of the rats. The enzyme-linked immunosorbent assay （ELISA） was used to examine the expressions of CRF and CRFR1 proteins in hypothalamus; the fluorescence-based quantitative polymerase chain reaction （PCR） was used to detect the expressions of CRF and CRFR1 mRNAs in hypothalamus. Results： Compared with the NG, the AWR score increased significantly and the OFT and EPM scores dropped significantly in the MG （all P〈0.05）, and the expressions of hypothalamic CRF and CRFR1 proteins and mRNAs increased significantly （all P〈0.01）. Compared with the MG and SHPMG, the AWR score dropped significantly and the OFT and EPM scores increased significantly in the HPMG （all P〈0.01）, and the expressions of hypothalamic CRF and CRFRI proteins and mRNAs decreased significantly （all P〈0.05）. There were no significant differences between the MG and the SHPMG （all P〉0.05）. Conclusion： HPM can down-regulate the abnormally increased expressions of CRF and CRFR1 proteins and mRNAs in hypothalamus of the TNBS-induced experimental colitis rats, which is plausibly one of its action mechanisms in mitigating visceral pain and the pain-related emotions in the experimental colitis rats.展开更多
