Methods According to the random mumber table, 104 cases of herpes zoster were randomized into an observation group and a control group, 52 cases in each one. In the observation group, the blocking method was used at the starting site and the ending site of herpetic zone, the surrounding needling method was applied toward the center of the painful zone, with horizontal needling technique; and the local pricking and cupping methods as well as the bloodletting at Longyan （Extra） acupoint were adopted. In the control group, Jiáj （夹脊 EX-B 2） at the corresponding affected nerve segments and the local Ashi points were selected and stimulated with electroacupuncture. The visual analogue scale （VAS） was adopted to determine the analgesic effect 20 min, 1, 6, 12, 24 and 48 h after treatment separately in each group. Results The onset time of analgesic effect in the observation group was shorter than that in the control group and the efficacy time of duration was longer than that in the control group （all P0.05）. The analgesic effect and the result of comprehensive efficacy assessment were superior to those of the control group （both P0.05）. Conclusion The comprehensive therapy of blocking, surrounding needling, pricking and cupping method combined with bloodletting at Longyan （Extra） achieves the significant analgesic effect on herpes zoster.展开更多
