RESUMO
@#Objective To study the coordination mechanism of brain induced by stimulating on acupoints of different meridians by means of constructing cerebral cortex functional networks reflecting actual brain functional connections. Methods A 128-lead electroencephalogram (EEG) recording and analysis system was used to collect the EEG signals of 14 healthy subjects (eight males and six females) aged 21 to 25 in resting state and magnetic stimulation on the acupuncture points of Guangming (GB37) and Neiguan (PC6) located in different meridians from October to November, 2017. Then EEG sources were localized by group independent component analysis and standard low-resolution brain electromagnetic tomography, and the statistical relationships of EEG components were calculated. Finally, alpha-wave cerebral cortex functional networks were constructed and analyzed based on complex network theory. Results The connections of brain regions associated with movement, vision increased in the stimulation of Guangming acupoint. The brain regions associated with movement, attention and working memory in the stimulation of the Neiguan acupoint were reduced in the network. Some common brain areas were activated and some changes of functional connections were similar. Conclusion The changes in the topological structure of brain networks are basically consistent with the efficacy of the acupuncture point during magnetic stimulation on Guangming and Neiguan of different meridians, however, it causes some similar changes in functional connectivity connections of some brain regions.
RESUMO
Objective To evaluate the clinical efficacy of different combinations with "Shugan Jianpi" acupuncture and Yintang acupoint magnetic stimulation in the treatment of depression with liver depression and spleen deficiency type.Methods 160 patients with depression treated in hospital from December 2013 to June 2017 were divided into 4 groups according to the random number table,with 40 cases in each group.Group A received basic drug therapy," Shugan Jianpi" acupuncture combined with Yintang acupoint magnetic stimulation,group B received basic drug therapy combined with Yintang acupoint magnetic stimulation,group C received basic drug therapy combined with " Shugan Jianpi" acupuncture treatment,group D was treated with basic medicine only for 4 weeks.Hamilton Depression Scale (HAMD) was used to assess the short-term and long-term efficacy for 4 groups before treatment,after 2 weeks of treatment,after 4 weeks and 2 months after treatment and the safety of these 4 types of therapy was evaluated with the side effects scale (TESS).2 months after the treatment,the quality of life universal scale (SF-36) was evaluated for patients in 4 groups.Results After 2 weeks,4 weeks and 2 months of treatment,HAMD scores in the 4 groups were significantly lower than those before treatment (P＜0.05).After 2 weeks of treatment,HAMD score of A group was (15.28±3.45),and HAMD score of B,C,D group were ((18.30±3.57),(22.50±3.71),(27.30±4.82)) respectively.HAMD score of A group was significantly lower than those of B,C,D group (P＜0.05).After 4 weeks of treatment,HAMD scores in A,B group were significantly lower than those in C,D group (P ＜0.05).After 2 months of treatment,HAMD scores in all the 4 groups were further declined compared with those after 4 weeks of treatment (P＜ 0.05),however,there was no significant difference between the four groups (P＞0.05).The scores of each dimension of SF-36 in group A were significantly higher than those of group B,C and D (P＜0.05),and which in group B and C were significantly higher than those in D group after 2 months of treatment.(P＜0.05).There was no statistical difference among the 4 groups in TESS scores (P ＞0.05).Conclusion The results suggest that there is a synergistic effect in combination of the " ShuganJianpi" acupuncture combined with Yintang acupoint magnetic stimulation in the treatment of depression of liver qi stagnation and spleen deficiency type,and it can effectively reduce the degree and improve their quality of life in patients with depression.
