RESUMO
Objective To investigate the effects of rTMS stimulation in different brain regions combined with paroxetine on treating patients with obsessive -compulsive disorders. Methods Outpatients and inpatients with obsessive-compulsive disorder(OCD) treated at Kangning Hospital of Ningbo province from March 2015 to December 2016 were collected. Patients were randomly divided into control group(29 cases), treatment group 1(30 cases) and treatment group 2(30 cases). Patients in control group were treated with paroxetine only. Patients in treatment group 1 received rTMS stimulation of right prefrontal lobe combined with paroxetine systemic treatment. Patients in treatment group 2 received rTMS stimulation of bilateral supplementary motor area with paroxetine treatment. Obsessive -compulsive idea and behavior were assessed using Y-BOCS before treatment and 1, 2, 4, 6, 8 weeks after treatment. Adverse reaction was assessed after treatment with TESS. Results The Y-BOCS score of the control group decreased significantly at the 6th and the 8th week of treatment compared with before (P＜0. 05). The Y-BOCS score of the treatment group 1 and group 2 were significantly lower at 4, 6 and 8 weeks of treatment than that of the control group (P＜0. 05). The Y-BOCS scores of treatment group 1 and group 2 were significantly lower after 4 weeks of treatment than those before treatment (P＜0. 05). Conclusion rTMS stimulation of the right prefrontal lobe and bilateral supplementary motor area combined with paroxetine in the treatment of obsessive -compulsive disorder has consistent efficacy and take effect rapidly with minor adverse reactions.
RESUMO
Objective To investigate effects of three kinds of neutral,happy,sad emotional faces stimulus on sustained attention task using N170 in depression patients to analysis the correlation of depression in patients with depression,anxiety severity and the amplitude and latency of N170.Methods Twenty-eight patients with depression aged from 22 to 69 years (case group),and 31 healthy controls (control group) aged from 20 to 61 years were recruited for the study.Subjects were asked to perform tasks in the selection of attention following randomly presented three kinds of happy,neutral and sad emotional faces stimuli.Brain auditory evoked potential including N170 amplitude and latency were recorded during the tasks.HAMD and HAMA were used to assess the severity of depression and anxiety.Results There was significant difference between case group and control group in N170 latency by three kinds of happy,neutral and sad emotional faces stimulation in the local skull (T5,T6,O1,O2) (P＜0.05).But the difference was not significant in N170 amplitude (P＞0.05).The total score of HAMD in case group had a positive correlation with N170 amplitude by neutral facial emotion stimulation in part of T5 (r=0.443,P=0.018).Conclusion There is significant change in the initial cognitive processing of different emotional faces in the patients with depression.And the severity of depression is related to the N170 amplitude induced by the neutral emotional faces stimulation in some parts of brain.
