头针对抑郁症患者脑葡萄糖代谢的影响

Effect of Scalp Acupuncture on Glucose Metabolism in Brain of Patients with Depression

目的 运用正电子发射型计算机断层显像(PET)技术,观察头针对抑郁症患者不同脑区葡萄糖代谢的影响。方法 12例抑郁症患者均接受头针治疗,取穴为顶中线(MS5)、额中线(MS1)和双侧额旁1线(MS2)。电针前和治疗6周后分别接受PET检测。框取感兴趣脑区(ROI),将各脑区所得葡萄糖代谢放射性计数采用半定量方式进行治疗前后比较。结果 上述穴位头针能升高双侧额叶、双侧顶叶、右侧扣带回、右侧尾核和左侧小脑葡萄糖代谢,降低右侧颞叶、双侧丘脑葡萄糖代谢。结论 电针抑郁症患者顶中线、额中线和双侧额旁1线能影响不同脑区的葡萄糖代谢,初步表明头针治疗抑郁症的机理与其调整皮质-边缘通路功能障碍、提高脑区葡萄糖代谢有关。

To observe the effect of scalp acupuncture (SA) on the glucose metabolism in different regions of brain in patients with depression by positron emission computed tomography (PET). Methods Twelve depressive patients were treated by scalp acupuncture on middle line of vertex (MS5) , middle line of forehead (MS1) and bilateral lateral line 1 of forehead (MS2) , once a day for six days per week, and received PET detection on different region of brain before and after 6 weeks acupuncture treatment. Semiquantitative analysis was used to compare the average values of radioactive count gotten from various brain regions before and after treatment, which could reflect the condition of glucose metabolism at the brain region detected. Results SA could increase the glucose metabolism at bilateral frontal lobes, bilateral parietal lobes, right occipital lobe, right caudate nucleus, right cingulated gyrus and left cerebellum and decrease that at right temporal lobe and bilateral thalamus. Conclusion SA on MS5, MS1 and MS2 in depressive patients could influence the glucose metabolism in various brain regions. It primarily illustrated that the mechanism of SA in treating depression is related with its regulation on cortex-limbic circuitry dysfunction and increase the glucose metabolism in various brain regions.
