Method A total of 60 SD rats were randomly divided into control group, model group, ST 37 group, Zúsānl？（足三里 ST 36） group, Xiàjùxū（下巨虚 ST 39） group and Yánglíngquán（阳陵泉 GB 34） group. There were ten rats in each group; five were males, and five were females. UC models were established by clysis with 2, 4, 6-trinitrobenzene sulfonic acid/alcohol solution. After modeling, treatment was conducted for ten days, specimens were collected, colonic ulcers and inflammation were inspected visually and scored. The content of serum IL-1β and the expressions of TNF-α and HMGB 1 in colon were detected through ELISA. Results 1 Compared with control group, the scores of colonic ulcers and inflammation, the content of serum IL-1β and the expressions of TNF-α（except ST 37 group） and HMGB 1 were all higher（P〈0.05, P〈0.01）; 2 compared with model group, the scores of colonic ulcers in ST 36 group and ST 37 group were lower obviously（P〈0.05, P〈0.01）; the expressions of IL-1β, TNF-α and HMGB 1 in the four treatment groups were lower obviously（P〈0.01）; 3 compared with ST 37 group, the expressions of IL-1β, TNF-α and HMGB 1 in other three treatment groups were higher obviously（P〈0.05, P〈0.01）; and the scores of colonic ulcers in ST 39 group and GB 34 group were higher obviously（P〈0.05）. Conclusion 1 The score of colonic ulcers can be reduced through electroacupuncture at ST 37, ST 36, ST 39 and GB 34, which can also reduce the content of serum IL-1β and the expressions of TNF-α and HMGB 1, and effectively inhibit inflammatory response of colon caused by UC; 2 the effect trend of the four acupoints in treatment of UC is： ST 37ST 36ST 39GB 34, and electroacupuncture at ST 37 has the best effect with relative specificity.展开更多

Methods Seventy healthy SD rats were randomly divided into seven groups, including control group, model group, ＂Zúsānlǐ＂（足三里 ST 36） group, ＂Shàngjùxū＂（上巨虚 ST 37） group, ＂Xiàjùxū＂（下巨虚 ST 39） group, ＂Yánglíngquán＂（阳陵泉 GB 34） group and ＂Chéngjīn＂（承筋 BL 56） group, with five male rats and five female rats in each group. Acute gastric mucosal lesion model was established by applying WRS method. After successful modeling and treatment for ten days, sampling was conducted, gastric mucosal lesion was observed visually and scored, the levels of serum HMGB 1 and gastric tissue TNF-α were detected by ELISA method, and the expression of NF-κB was detected by immunohistochemical method. Results①Compared with the model group, the levels of Ulcers and inflammation（UI） in gastric mucosal and serum HMGB1, and the expression of gastric tissue TNF-α and NF-κB in the four lower he-sea points groups reduced（P〈0.01 or P〈0.05）;② compared with ST 36 group, the levels of gastric mucosal UI and serum HMGB1, and the expression of gastric mucosal TNF-α and NF-κB in other treatment groups increased significantly, and the difference was statistically significant（P〈0.01 or P〈0.05）. Conclusion①Electroacupuncture at relevant lower he-sea points can inhibit the body＇s immune response, relieve inflammatory reaction and reduce mucosal lesion by regulating HMGB 1, TNF-α and NF-κB, so as to realize the intervention and treatment on AGML rats;② the total intervention effect in ST 36 group is superior to that in other groups, indicating partially that there is a relative specificity between ST 36 and stomach.展开更多
