针刺对原发性抑郁症患者脑干诱发电位的影响

目的：观察针刺对原发性抑郁症患者脑干诱发电位的影响以及针刺的疗效。方法：40例原发性抑郁症患者针刺百会、印堂、大椎、神门、太冲、内关、三阴交，留针30min，隔天治疗1次，每周治疗3次，治疗6N后观察脑干听觉诱发电位（BAEP）和视觉诱发电位（VEP）；观察抑郁症患者治疗前后汉密尔顿抑郁量表（HAMD）评分变化情况。结果：抑郁症患者治疗后VEP各渡潜伏期均显著缩短（P〈0．05），BAEPIII波潜伏期显著缩短（P〈0．05），患者的HAMD评分明显改善。结论：抑郁症患者中枢神经系统对视觉、听觉刺激的应激能力下降；针刺能明显缩短抑郁患者脑干诱发电位的潜伏期；针刺治疗原发性抑郁症患者有效。

Impacts of acupuncture on brainstem evoked potentials in patients with primary depression

Objective To observe the impacts of acupuncture on brainstem evoked potentials in the patients with primary depression. Methods Forty cases of primary depression were treated by acupuncture at Baihui （百会 GV 20）, Yinatng （印堂 GV 29）, DazhuT （大椎 GV 14）, bilateral Shenmen （神门 HT 7）, bilateral Taichong （太冲 LR 3）, bilateral Neiguan （内关 PC 6） and SanyTnjiao （三阴交 SP 6）. The needles were retained for 30 min. Acupuncture treatment was given once every two days, three treatments a week. The brainstem auditory evoked potential （BAEP） and visual evoked potential （VEP） were observed in 6 weeks of treatment. The change in Hamilton depression scale （HAMD） score was observed before and after treatment in the depression group. Results After treatment, VEP wave latency was shortened significantly in patients of depression （P〈0.05）, BAEPIII wave latency was shortened significantly （P〈0.05）. The score of HAMD was decreased apparently in the depression group （P〈0.05）. Conclusions The stressability of visual and auditory stimuli in the central nervous system was decreased in the patients of depression. Acupuncture shortens remarkably the brainstem evoked potentials latency in the patients of depression and achieves the effective results in the treatment of primary depression.
