脑血流显像对眼针治疗脑梗塞的疗效评价

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

为了评价眼针疗法对脑梗塞患者时即时疗效,本工作以99Tcm-ECD为显象剂对脑梗塞组10人先后两次进行SPECT脑血流显像,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后局部脑血流量(rCBF)的改善率。结果显示,脑梗塞患者静息状态下有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36.67%。以上结果提示,一日法99Tcm-ECD SPECT脑血流显像对评价眼针治疗脑梗塞疗效有一定的临床应用价值。

To evaluate the immediate effect of ocular acupuncture on patients, an method of SPECT image of cerebral blood flow daily stress test was established. 10 patients diagnosed as cerebral infarction by CT or MRI were tested. They all received ^99Tc^m-ECD SPECT imaging at twice before and after ocular acupuncture. By means of image subtraction technique and semiuantitative method of regional interesting area, the change of regional cerebral blood flow was observed between the two images. Under restful state perfusion of cerebral blood flow in 18 foci was low at the frontal lobe, the cerebellum, the basal ganglia and temporal lobe. After ocular acupuncture, the perfusions were obviously increased in 16 foci among them and the reactivity of the frontal lobe and the cerebellum to ocular acupuncture was higher, the average improvement rate of which was 55.15% and 53.06% respectively, lower in the basal ganglia and temporal lobe, the average improvement rate was 31.79% and 36.67 % respectively. ^99Tc^m-ECD SPECT cerebral perfusion image has some significant clinic value for evaluating the effect of ocular acupuncture to treating cerebral infarction.
