Effects of electroacupuncture at lower he-sea points on interleukin-1β and high mobility group box 1 in model rats with ulcerative colitis

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; the effect trend of the four acupoints in treatment of UC is: ST 37>ST 36>ST 39>GB 34, and electroacupuncture at ST 37 has the best effect with relative specificity.
