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.

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.

Objective To study the effect of olanzapine combined with repetitive transcranial magnetic stimulation(rTMS) in the treatment of phonism dominated schizophrenia.Methods From August 2015 to November 2016,112 patients with phonism based schizophrenia in Ningbo Kangning Hospital were selected in the research . According to the different treatment ,the patients were divided into observation group and control group ,with 56 cases in each group.The observation group was treated with olanzapine combined with rTMS chemotherapy ,the control group was treated with olanzapine.Before and after treatment,the positive and negative symptom scale ( PANSS) score, Wisconsin Card Sorting Test ( WCST) score of the two groups were observed.The clinical efficacy was compared between the two groups.Results Before treatment,there were no statistically significant differences in PANSS score and WCST score between the two groups ( all P＞0.05).After treatment for 1 week,2 weeks,4 weeks,the PANSS scores of the two groups were significantly lower than those before treatment (F＝170.710,106.028,28.530,30.328, 25.806,10.832,203.342,372.253,all P＜0.05).The PANSS scores decreased more significantly in the observation group.After treatment for 1,2,4 weeks,the scores of positive symptoms in the observation group were (25.95 ±3.50)points, (24.72 ±4.50)points and(16.51 ±2.70)points,respectively,which were significantly lower than those in the control group[(27.27 ±2.03)points,(27.80 ±5.37)points,(19.53 ±3.07)points](t＝2.441,3.290,5.528,all P＜0.05).After treatment for 1 week,2 weeks,4 weeks,the continuous response scores in the observation group were (45.62 ±5.41)points,(44.69 ±4.91) points,(35.89 ±3.30) points,respectively,which were significantly lower than those in the control group[(50.61 ±5.35)points,(46.80 ±5.14)points,(42.70 ±5.04)points](t＝4.908, 2.221,8.459,all P＜0.05).The scores of continuous errors in the observation group were (49.47 ±4.59) points, (46.53 ±6.05) points and (36.35 ±5.18) points,respectively,which were lower than those in the control group [(83.1 ±6.58)points,(81.85 ±6.70)points and (76.86 ±76.86)points](t＝31.369,29.279,38.464,all P＜0.05).After treatment for 1 week,2 weeks,the classification scores in the observation group were (4.21 ±2.03) points and (5.35 ±2.23) points,respectively,which were significantly higher than those in the control group [(3.35 ±1.24)points and (3.95 ±1.24)points] (t＝2.705,4.106,all P＜0.05).The effective rate was 91.0%in the observation group ,which was 89.2%in the control group,there was no statistically significant difference (χ2＝0.022,P＞0.05).Conclusion Olanzapine combined with rTMS is effective in the treatment of schizophrenia ,and olanzapine combined with rTMS is more effective in improving the cognitive ability of patients than olanzapine alone .

Objective To explore the clinical features, treatment and follow-up of Cockayne syndrome with renal involvement. Method The clinical data of one child with Cockayne syndrome confirmed by gene detection with renal injury were reviewed, and the clinical features of renal involvement in Cockayne syndrome were summarized. Results A male child aged 3 years and 8 months had clinical manifestations of mental retardation, growth retardation, special face and photosensitive dermatitis, and renal involvement was manifested by nephrotic syndrome. Cranial CT showed symmetrically calcification in bilateral basal ganglia. The targeted next generation sequencing results showed homozygous mutations of c.394_398del and p.Leu132Asnfs in ERCC8 gene (NM_000082) of the child, and the same heterozygous mutation was found in both his parents (non-consanguineous marriage). After the diagnosis of nephrotic syndrome, full dose prednisone was given for experimental treatment. The urine protein decreased but did not disappear, which was considered hormone resistance. After 4 months of combined treatment with cyclosporin, the urine protein turned negative. During 20 months of follow-up, urine protein remained negative and renal function remained stable. The renal involvement in Cockayne syndrome was seldomly reported, and its clinical manifestations are heterogeneous. Condusion Renal involvement in Cockayne syndrome may be manifested with nephrotic syndrome which should be noticed.

Objective: The present study was aimed to explore the role and distinctive mechanism of SPIDR, the key regulatory protein of homologous recombination pathway, in progression of small cell lung cancer (SCLC). Methods: 60 SCLC specimens and 44 normal lung tissues were collected from the patients undergoing tumor resection and bronchoscopic puncture in Shanghai Pulmonary Hospital Affiliated to Tongji University from January 2013 to January 2015. The expression of SPIDR in clinical samples and NCIH446 (SCLC cell line) and MRC-5 (normal cell line) were assayed by Real-time PCR. The role of SPIDR in SCLC was investigated in vivo and in vitro by the expression of SPIDR were artificially modified in NCI-H446. Results: Smoking was significantly associated with the occurrence of SCLC (P<0.01). The expression of SPIDR mRNAin SCLC tissues was lower than that of normal lung tissues (P <0.01), and the SPIDR transcriptional and translational levels of NCI-H446 cells were also lower than that of MRC-5.Although there is no significant changes of cell growth rate and susceptibility to cisplatin and etoposide in the NCI-H446 cells overexpressing SPIDR. However, the volume of xenograft tumors of overexpressed SPIDR group decreased by 58.99% (P<0.01) and 61.84% (P<0.01) than that of the original NCI-H446 cells and the NCI-H446 cells transfected with vector (pMSCV) and the average tumor mass decreased by 61.70% (P<0.01) and 70.25% (P<0.01) respectively. When the fetal bovine serum content in the medium was reduced to 3%, the growth rate of NCI-H446 cells overexpressing SPIDR was 22.33% (P<0.01) and 20.24% (P<0.05) lower than that of the original NCIH446 cells and control group, the similar results were obtained from the 1% serum concentration experiment as well. Conclusion: The expression of SPIDR, the key regulatory protein in the DNAdouble strand break homologous recombination repair pathway, was significantly suppressed in SCLC tissues, which markedly accelerated the growth of NCI-H446 cells in vivo and reduced the reliance of NCIH446 cells to the serum. The detailed mechanism is worthy of further investigation.
