艾灸对胶原诱导性关节炎大鼠血清白介素-17和肿瘤坏死因子α含量的影响

目的:观察艾灸对胶原诱导性关节炎(CIA)大鼠血清白介素-17(IL-17)和肿瘤坏死因子-α(TNF-α)含量的影响,探讨艾灸对类风湿性关节炎的作用机制。方法:将Wistar大鼠随机抽取8只为空白组,剩余大鼠制备CIA模型。初次免疫乳剂采用鸡Ⅱ型胶原与弗氏完全佐剂制备,0.3mL乳剂(含0.3mg胶原)分别等量皮下注射于大鼠左足底部、尾根上和背部。初次免疫7d后,同法诱发继发免疫,继发免疫乳剂由鸡Ⅱ型胶原与弗氏不完全佐剂制备,总共造模21d。将造模成功的24只大鼠随机分为模型组、药物组和艾灸组,每组8只。艾灸组用小艾条距"足三里"和"昆仑"穴20mm处悬灸,每穴20min,共40min,1次/d,左右肢交替进行,连续干预10d。药物组用0.1mg/100g甲氨蝶呤氯化钠溶液灌胃,1次/5d,共2次。于造模前后及治疗后测量各组大鼠左踝关节直径、体质量;治疗结束后拍摄左足跗部X光片,ELISA法检测大鼠血清中IL-17和TNF-α的含量。结果:造模后,与空白组相比,模型组大鼠踝关节直径、血清IL-17和TNF-α含量升高(P<0.05),体质量下降(P<0.05),X线下可见足跗部关节软组织肿胀,关节间隙变窄,骨质破坏;干预后,与模型组相比,药物组和艾灸组大鼠踝关节直径、血清IL-17和TNF-α含量下降(P<0.05),体质量升高(P<0.05),足跗部软组织肿胀减轻,骨骼畸形好转;药物组和艾灸组相比,各指标差异均无统计学意义(P>0.05)。结论:艾灸对CIA大鼠具有与甲氨喋呤类似的作用,其机制之一可能是艾灸可降低CIA大鼠血清中IL-17和TNF-α的含量。

Clinical Observation on Acupuncture Treatment for Painless Labor

Objective： To observe the clinical effects of acupuncture for relieving pain in delivery. Methods： 240 cases of parturients were randomly divided into a treatment group and a control group, 120 cases in each group. The treatment was given by puncturing Kunlun （BL 60） immediately in the incubation period of labor course in the treatment group. The control group was treated by giving intermittent oxygen inhalation. Results： Pain was relieved obviously in the treatment group, with statistical significance compared with the control group （P〈0.01）. Conclusion： Acupuncture at Kunlun （BL 60） can relieve delivery pain of parturients during the delivery process and is a feasible painless method for delivery.
