Objective To investigate the clinical safety and efficacy of mechanical thrombectomy(MT) with Solitaire stent compared with the selective intra-arterial thrombolysis (IAT) in the treatment of acute cerebral infarction.Methods Totally 82 cases patients with severe acute ischemic stroke caused by middle cerebral artery stenosis from January 2014 to May 2016 in the stroke treatment center of the first people's Hospital in ZunYi city who were applied with the mechanical thrombectomy or the selective intra-arterial thrombolysis was included,and a comparative analysis was conducted on the mTICI rating to assess the interventional recanalization,the NIHSS score after the treatment,bleeding rate,and conditions of neurological functional recovery 90 days after operation.Results There were 42 cases applied with the mechanical thrombectomy (MT group),40 cases applied with the intra-arterial thrombolysis (IAT group).The total effective rate reached 85.70％ in the MT group and 62.50％ in the IAT group,the difference was significant (P ＜ 0.05).Compared with NIHSS score before operation,the score after the treatment showed a decreased trend.And the NIHSS score of MT group was better than that of the IAT group in a week after the treatment (P ＜ 0.05).The bleeding rate was lower in the MT group with statistically significant difference (P ＜ 0.05).Conclusion Compared to IAT,MT can provide broader time window,higher recanalization rate and better outcome in patients with severe acute ischemic stroke.

Objective To investigate the association between catechol-O-methyltransferase (COMT) Val158Met polymorphism and the memery function of schizophrenia treated with Aripiprazole.Methods Schizophrenic patients were diagnosed in according to Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV).A total of 78 Chinese Han subjects were involved in this study.The polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) was used to identify COMT genotypes.The Chinese revised version of Wechsler Memory Scale (WMS-RC) was used twice to evaluate the memory function of patients treated with Aripiprazole alone before and after drug treatment for 8 weeks.ANOVA,rank sum test and t-test were used to statistical analysis.Results There was statistical difference of cumulative memory among the three groups (F=12.371,P=0.002),and Met/Met genotype showed much poorer cumulative memory than Val/Met and Val/Val genotypes (Z=-3.168,-2.641 ; P=0.002,0.008,respectively) Memory function was significantly improved after patients been treated with Aripiprazole except the associative memory(P＜0.05).Met/Met genotype showed more improvement of cumulative memory than other genotypes after Aripiprazole treatment (t=4.203,P＜0.01 ; t=3.024,P ＜0.01,respectively).Conclusions There may be a relationship between COMT Val158Met polymorphism and the memory function of schizophrenia in Aripiprazole treatment.Met/Met genotype of schizophrenia showed worst cumulative memory but best responsiveness in Aripiprazole treatment.

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.
