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
