Methods： Forty male Wistar rats were randomly divided into 4 groups： a normal group, a model group, a Shangjuxu group and a non-acupoint group, 10 rats in each group. The UC rat model was made with enema of trinitro-benzenesulfonic acid （TNBSA）, and the changes of interleuldn-1β （IL-1β） and interleukin-4 （IL-4） contents after EA at Shangjuxu （ST 37） were observed. Results： EA at Shangjuxu （ST 37） could significantly decrease the IL-1β content and increase the IL-4 content in the colic tissues of the UC rats with significant differences as compared with the model group and the non-acupoint group （P〈0.05 or P〈0.01）. Conclusion： The mechanisms of EA at Shangjuxu （ST 37） for treatment of the UC rats is possibly related with the decrease of IL-1β, a inflammation-promoting cytokine, and the increase of IL-4, a anti-inflammatory cytokine.展开更多

The relative specificity of acupoints was also explored. Methods： A total of 28 male Wistar rats were randomized into a normal group, a model group, a Chize （LU 5） group and a Shangjuxu （ST 37） group, 7 rats in each group. The UC model was established by enema with acetic acid. Since the third day after modeling, rats in the Chize （LU 5） group and Shangjuxu （ST 37） group respectively received EA at Chize （LU 5） and Shangjuxu （ST 37）, 1S min each time for successive 7 d. The variations of mesenteric microvascular calibers and blood flow status were observed by a microcirculation microscopic tester; VIP in the colon, lung and hypothalamus was measured by radioimmunoassay. Results： Compared with the normal group, the mesenteric microvascular calibers were significantly expanded in the model group （P〈0.05）; there was no significant difference between the model group and Chize （LU 5） group （P〉0.05）; compared with the model group and Chize （LU 5） group, the calibers were obviously shrunk in Shangjuxu （ST 37） group （P〈0.05）. The four groups showed no significant inter-group differences in comparing blood flow status （P〉0.05）. The colonic VIP levels in the model group and Chize （LU 5） group were significantly higher than that in the normal group （P〈0.01, P〈0.05）; the VIP level in Shangjuxu （ST 37） group was markedly lower than that in the model group （P〈0.01）. There were no significant differences among the four groups in comparing VIP level in lung and hypothalamus （P〉0.05）. Conclusion： The effects of Chize （LU 5） and Shangjuxu （ST 37） were different in treating UC. Shangjuxu （ST 37） showed a more significant efficacy in down-regulating VIP in the colon and regulating mesenteric microcirculation, while the effects of Chize （LU 5） were not obvious.展开更多
