OBJECTIVE: To study the impacts of electroacupuncture (EA) on memory impairment after cerebral infarction through the observation of hydrogen proton magnetic resonance spectroscopy (1H-MRS) of brain tissue metabolites in the patients of cerebral infarction. METHODS: Sixty cases of memory impairment after cerebral infarction were randomized into an observation group and a control group, 30 cases in each one. The conventional rehabilitation training and medication were applied to all the patients. In the observation group, beside the basic treatment, EA was applied to bilateral Ezhongxian (MS 1), Dingzhongxian (MS 5), Dingniehouxiexian (MS 7), Hegu (LI 4), Taichong (LR 3), Zusanli (ST 36), Taixi (KI 3), Xuanzhong (GB 39) and Fengchi (GB 20). The treatment was given once a day, 5 times a week, for 8 weeks. The clinical memory scale was used for the score evaluation before and after treatment in all the patients. The magnetic resonance image (MRI) and 1H-MRS scanning were applied to the head. The ratio of N-acetyl aspartate (NAA) and creatine (Cr) and the ratio of choline (Cho) and Cr were determined in the foci of cerebral infarction. RESULTS: Eight weeks later, the scores of clinical memory scale were all increased after treatment as compared with those before treatment in the two group (all P<0. 01). The ratio of NAA and Cr was increased as compared with that before treatment (P<0. 05); the ratio of Cho and Cr was reduced as compared with that before treatment (P<0. 05). The changes in the observation group were more obvious than those in the control group (all P<0. 05). CONCLUSION: On the basis of the conventional medication and rehabilitation training, EA improves the metabolism of brain tissue and memory function of the patients. The efficacy of this therapy is better than that of medication combined with rehabilitation training.
