Objective To explore the executive function and working memory ability of patients with social phobia. Methods The study included 42 social phobia patients whose age, sex, and level of education were matched with those of a healthy control group. Wisconsin Card Sorting Test and Digit Span, Spatial Span, Multiple-Objects-Spatial span were used to study the executive function and working memory. Results Patients with social phobia scored higher than the control group in terms of the number of non perseverative errors on the Wisconsin Card Sorting Test ( 18. 75 ± 6. 20, 8. 89 ± 3. 22 respectively ). No differences were observed in perseverative errors and other scores between the patient and control group. Patients with social phobia scored lower than the control group in terms of Digit Span(7.25 ±1.35,8.03 ±2. 30 respectively) ,Spatial Span(6. 11±1.85,8.61 ±2.87 respectively) and Multiple-Objects-Spatial span(4.03 ± 1. 39 ,5. 18 ± 1.07 respectively). Conclusion Working memory ability in the social phobia patients is impaired, and this may cause the poor performance in patients with the social phobia in academic and social working.

ObjectiveTo explore the influence of clinical symptoms and applicability of discontiguous naikan cognitive therapy(DNCT) among convalescent schizophrenic patients.MethodsApplying DNCT,100 convalescent paranoid schizophrenic patients with convalescent clinical state were consecutively recruited.All the patients were randomly divided into DNCT group and control group and were pretreated with antipsychotic agent therapy,40 patients in DNCT group and 49 patients in control group entered the statistic analysis,11 lost.In DNCT group,the patients received DNCT for successive 28 days.In control group,the patients only received antipsychotic agent therapy.Positive and Negative Syndrome Scale (PANSS),Nurses'Observation Scale for Inpatient Evaluation (NOSIE) were administered to all subjects pre- and post-treatment.ResultsAfter treatment,in the study group,total PANSS scales ( (54.00 ± 10.19 ) vs (45.05 ± 5.28 ),t =5.430,P ＜ 0.01 ),the positive symptom item ((11.00±3.33) vs (9.53 ±1.85),t=3.670,P=0.01),negative symptoms item((12.15 ±4.38) vs (9.40± 2.15 ),t =4.371,P ＜ 0.01 ),general psychopathology item ( (26.90 ± 5.66) vs (22.65 ± 3.07 ) 分,t =4.494,P＜0.01 ) scored lower than before,The difference was statistically significant.PANSS study group after treatment,total scores( (45.05 ±5.28 ) vs (52.04 ± 10.36),t=-3.876 P＜0.01 ),negative symptom item score( t =- 3.789,P ＜ 0.01 ),composite item ( t =2.251,P =0.027 ),the general psychopathology item ( t =- 3.336,P =0.01 ),score significantly lower than the control group.After twelve weeks follow-up study,in the study group,PANSS total scores ( t =4.764,P ＜ 0.01 ),item score of positive symptoms ( t =2.335,P =0.025 ),negative symptoms item score( t =3.083,P =0.004) ),genial psychopathology item score ( t =4.325,P ＜ 0.01 ) was still significantly lower than before treatment,the difference was statistically significant.In study group,after treatment,NOSIE Scale total negative factors scores( t =3.083,P =0.004) were significantly lower than before,total positive factors( t =-2.446,P=0.019),the total estimated factor in the disease scores ( t =-4.730,P ＜ 0.001 )were significantly higher than before treatment.After treatment,in the study group,negative factors ( t =-3.953,P=0.000) were significantly lower than the control group,twelve weeks follow-up,study group total negative factors of NOSIE scale score( t =2.126,P =0.040) was still lower than before treatment,the difference was statistically significant,total positive factor( t =- 2.054,P =0.047 ) still higher than before treatment,the difference was statistically significant.ConclusionDNCT can possibly improve part clinical symptoms of patients with convalescent schizophrenia to a certain extent,especially negative symptom,and the impact remained to the twelve weeks,but need to further prove the effect of naikan cognitive therapy.

Objective To explore the difference of the oxytocin levels between social phobia patients and normal controls,and the relationship of symptoms severity of social phobia with the oxytocin levels and the relationship of drug effects with oxytocin levels.Methods Twenty seven 16-26 years old social phobia patients and thirty one normal controls were tested by an enzyme-linked immunosorbent assay to evaluate the oxytocin levels,and the Liebowitz Social Anxiety Scale was used to evaluate the symptoms severity of social phobia in patient group.Paroxetine was used to treat the patients with the drugs of 20mg per day,the Clinical Global Impression Scale were used to evaluate the drug effects after 4 weeks treatment.Results Mann-Whitney test showed there were significantly differences in oxytocin level between patients and controls ( (202.93 ± 145.06) pg/ml vs ( 152.29 ± 101.89 ) pg/ml,Z =- 1.307,P=0.030).Multiple liner regression analyses showed that the level of oxytocin was an impact factor of the severity of social phobia symptom (adjusted R2 =0.158,F=5.888,P=0.023 ).Logistic regression analyses showed that the level of oxytocin was an impact factor of the effective of drug treatment( OR=3.132,P =0.029 ).Conclusion This study indicate that the value of plasma oxytocin maybe significantly differences between social phobia and normal controls and the plasma oxytocin level maybe a factor which influence the symptoms severity and the effective of drug treatment in social phobia patients.

Objective To assess the clinical utility of P300 for the assessment of cognitive disorders in Chinese patients with Parkinson's disease (PD) by meta-analysis.Methods Studies comparing the P300 between PD patients with different cognitive disorders (dementia,mild cognitive impairment (MCI),and no cognitive impairment;the former two were “cognitive impairments”,while the latter two were “nondementia”) and healthy controls were retrieved by searching within major Chinese and English databases.Studies,whose case and control groups were matched for age and gender,were rated as high quality.Weighted mean differences (WMDs) in P300 latency and amplitude between groups were calculated by using meta-analysis.Results In total,23 studies were included and 20 of which were rated high quality.Demented PD patients had statistically significant longer P300 latency (WMD:56.14,95％ CI:19.06,93.23) and lower amplitude (WMD:-1.30,95％CI:-2.08,-0.51) than non-demented PD patients.PD patients with MCI had statistically significant longer P300 latency (WMD:13.71,95％CI:5.13,22.29) and lower amplitude (WMD:-1.25,95 ％ CI:-2.29,-0.21) than PD patients without cognitive disorders.However,no significant differences in P300 latency (WMD:4.16,95％ CI:-13.85,22.17) and amplitude (WMD:0.23,95％ CI:-1.72,2.17) were found between PD patients with dementia and MCI.Conclusion Among Chinese PD patients,there are significant P300 differences between those with dementia and without dementia,and between MCI and those without cognitive impairments,however,but no significant P300 differences between those with dementia and MCI.

Objective To explore the relationship between m6A RNA methylation regulators and prognosis of prostate cancer.Methods Clinicopathological and mRNA-related data of 496 cases of prostate cancer were downloaded from the Cancer Genome Atlas(TCGA)database,and 12 m6A regulators were identified:METTL3,METTL14,WTAP,RBM15,ZC3H13,YTHDC1,YTHDC2,YTHDF1,YTHDF2,HNRNPC,FTO,and ALKBH5.The m6A regulators differentially expressed in prostate cancer samples were screened.Unsupervised clustering of prostate cancer tissues was used to compare differences in overall survival.Multivariate Cox regres-sion analysis was used to divide patients into high-and low-risk groups according to the risk scores,and survival rates were compared.The risk score of clinicopathological factors was determined,and a multivariate Cox regression analysis model was constructed to evaluate the prognostic prediction value.Immunohistochemical staining was performed to detect METTL14 and FTO expression in prostate cancer tis-sues.Results Eight differentially expressed regulators were screened from 12 m6A regulators.Unsupervised cluster analysis divided the samples into Clusters 1,2,and 3 and found significant differences in survival time in all three groups.Multivariate Cox regression analyses revealed that METTL14and FTOwere strongly associated with the prognosis of patients with prostate cancer.A Cox regression model con-structed to score the risk of prostate cancer revealed that the high-and low-risk groups had survival differences,and the risk score could be used as an independent prognostic factor.The positive expression rates of METTL14 and FTO protein in prostate cancer tissues were significantly higher than those in adjacent tissues(P<0.05).Conclusion In this study,a prognostic prediction model based on m6A regulators of prostate cancer was constructed,in which the risk score could be used as an independent prognostic factor.METTL14and FTOcould be used as molecular markers for the diagnosis of prostate cancer and as potential targets for treatment.
