脑血流显像对眼针治疗脑梗塞的疗效评价

目的：应用脑血流SPECT显像一日负荷法，评价眼针疗法对脑梗塞患者的即时疗效。方法：对照组20人，均为健康人，脑梗塞组10人，经CT或MRI确诊的脑梗塞患者，两组均先后两次接受99mTc－ECD SPECT显像，利用图像减影技术及局部感兴趣区半定量分析法，观察治疗前后局部脑血流量（rCBF）变化。结果：对照组针刺后额叶、颞叶、基底节和小脑皮质增高为主。脑梗塞组静息状态下18处脑血流分布低下，针灸治疗后，16处病灶脑血流明显改善，2例无明显改善。额叶和小脑病灶对眼针的反应性较高（平均改善率分别为55.15％和平均改善率53.06%）；基底节和颞叶对眼针的反应性相对稍低（平均改善率分别为31.79％和平均改善率36.67%）。结论：一日法99mTc－ECD SPECT脑血流显像对评价眼针治疗脑梗塞疗效有临床应用价值。

Evaluation of Ocular Acupuncture on Cerebral Infarction With Cerebral Blood Flow Perfusion Imaging

Objective to evaluate the immediate effect of ocular acupuncture on patients with cerebral infarction by SPECT image of cerebral blood flow daily stress test，to explore the mechanism about treating cerebral infarction by ocular acupuncture. Material and Methods Comparable group are 20 healthy people and experimental group are 10 patients diagnosed as cerebral infarction by CT or MRI. They all received two times of 99mTc－ECD SPECT image before and after ocular acupuncture. By means of image subtraction technology and semi-quantitative method of regional interesting area，change of regional cerebral blood flow was observed between the two images. Result After acupuncture hypoperfusion of cerebral blood flow was found at the frontal Lobe、the cerebellum、the basal ganglia and temporal lobe. Under resting hypoperfusion of cerebral blood flow was found in 18 areas. after ocular acupuncture cerebral blood flow was improved obviously in 16 areas，not obviously in 2 areas. Reactivity was high in focus of the frontal Lobe and the cerebellum（average improvement rate was 55.15% and 53.06% respectively），low in the basal ganglia and temporal lobe（average improvement rate was 31.79% and 36.67% respectively）.Conclusion 99mTc－ECD SPECT cerebral perfusion image has significant clinic value for evaluating the effect about ocular acupuncture to treat cerebral infarction.
