Objective To study the attentional deployment strategy of emotion regulation and its processing mechanisms in alexithymia.Methods 21 alexithymia subjects and 22 normal subjects completed attentional deployment task.The reaction time(RT) and accuracy were recorded automatically and the event-related potentials (ERPs) were recorded by neuroscan system.Results ①From the behavioral results,the differences of RT and accuracy to neutral pictures ((1840.17±204.44) ms vs (1845.17±252.97) ms;(0.859±0.073) vs (0.884±0.068)) and negative pictures ((1888.94±200.09) ms vs(1890.38±263.72) ms);(0.845±0.088) vs (0.845±0.091)) in calculation task between two groups were not statistically significant(all P＞0.05).The differences of RT and accuracy in emotion task were not statistically significant(P＞0.05).②In RT and accuracy,the task main effects were statistically significant(F(1,42) =637.40,P＜0.01;F(1,42)=15.00,P＜0.01),the emotion main effects were statistically significant (F(1,42)=30.23,P＜0.001;F(i,42)=47.87,P＜0.01),the interaction effects of task and emotion were statistically significant(F(2,41) =5.20,P＜0.05;F(2,41)=6.01,P＜0.05).③The differences between two groups in P3 amplitude induced by neutral pictures and negative pictures in calculation task were not statistically significant(P＞0.05).P3 amplitude induced by negative pictures were siguificantly greater than those induced by neutral pictures in emotion task((-0.138±0.463) μV vs (0.789±0.541) μV).Conclusion The attentional deployment can effectively regulate the negative pictures processing and occur in the late stage of the picture processing.No attentional deployment defects in alexithymia.

Objective:To explore the correlation between hypersomnia and anhedonia in patients with major depressive disorder.Methods:From November 2018 to May 2019, patients hospitalized with major depressive disorder who met the ICD-10 diagnostic criteria were selected.According to the Epworth Sleepiness Scale (ESS), 46 patients were divided into daytime sleepiness group with ESS ≥ 7, and 171 patients were divided into non-sleepiness group with ESS < 7.The Chinese Revised Social Anhedonia Scale (RSAS) and the Chinese Revised Physical Anhedonia Scale (RPAS) were used to evaluate the patients' anhedonia symptoms.Two-way ANOVA and Pearson correlation analysis were used for data processing.Results:(1)There was no interaction between the hypersomnia and gender on the score of physical anhedonia ( F=0.274, P=0.601). The main effect analysis showed that there was significant difference in the influence of gender on physical anhedonia ( F=10.948, P<0.05). (2)There was interaction between the hypersomnia and age on the score of physical anhedonia ( F=4.396, P=0.013). Further simple effect analysis showed that the score of physical anhedonia in 40-49 age(21.54±12.37) was lower than that in 50-64 age(34.13±12.53) in daytime sleepiness group( P<0.05). (3) There was interaction between hypersomnia and sitting and lying on the score of social anhedonia ( F=4.247, P=0.041). Further simple effect analysis showed that the score of social anhedonia in patients with sitting and lying time less than 2 hours (13.71±5.18) was lower than that in patients with sitting and lying time more than 2 hours (19.75±6.39) in daytime sleepiness group( P<0.05). (4)Pearson correlation analysis showed that the total sleepiness score of depression patients was positively correlated with the social anhedonia score ( r=0.206, P<0.01). After adjusting for gender, age and sitting and lying time, the total sleepiness score was still positively correlated with the social anhedonia score( r=0.225, P<0.01). Conclusion:Hypersomnia may be associated with anhedonia in patients with major depressive disorder.

ObjectiveTo explore the relationship among dream threat level,life events and childhood trauma in obsessive-compulsive patients.Methods 59 obsessive-compulsive patients and 57 healthy controls were tested with Dream Threat Questionnaire (DTQ),Childhood Trauma Questionnaire ( CTQ ) and Life Events Scale (LES).The dream threat level were compared between the two groups,and correlation and regression analysis were used to research the relationship of the variables for patients’ data.ResultsCompared with the healthy controls,patients had significantly higher DTQ score ( 1.40 ± 2.23 vs 3.31 ± 3.04,P ＜ 0.01 ),CTQ total score (34.21 ± 8.47 vs 43.02 ± 10.78,P ＜ 0.01 ),LES total score ( 16.88 ± 16.42 vs 45.39 ± 46.01,P ＜ 0.01 ) and its negtive life events subscore ( 14.14 ± 14.61 vs 39.56 ± 42.94,P ＜ 0.01 ).Correlation analysis showed that dream threat level,negative life events and childhood trauma were significantly positively correlated each other( r =0.326 ～0.402,P ＜ 0.05 ～0.01 ).Regression analysis indicated that childhood trauma directly predicted dream threat level (β =0.104,P ＜ 0.05 ) and completely mediated the relationship between negative life events and dream threat level.ConclusionObsessive-compulsive patients have higher dream threat level,more childhood trauma experience and life events.Childhood trauma experience is a significant factor influencing dream threat level,and as a complete mediation by which life events influence dream threat level.

Objective To evaluate the antiretroviral therapy(ART),analyze the prevalence of resistance in rural areas,Henan,and explore the presence of minor resistant variants in pre-ART.Methods One hundred and forty-nine AIDS patients initiating ART were recruited and investigated at intervals of 6 months. Method of In-house developed by our laboratory for genotypjc resistance test was to analyze the occurrence of resistance among the failure of ART,and the allele-specific real.time PCR(ASPCR)was used to detect the minor resistant variants at the baseline samples once the resistance occurred.Results Vimlload significantly decreased among the patients who received ART(t=275,P=0.0001),but the absolute counts of CD4+T lymphocytes had no significant change(t=1.765 168,P=0.0852).Rate of resistance among the patients of treatment failure was 4.88%.The result of ASPCR in the survey of baseline showed that the minor resistant variants of M184V were detected in 7 patients and mutation K103N presented in 5 patients.Conclusion The primary drug-resistant straias in the untreated patients were found in Henan,and they might develop the dominant resistance strains and bring about the failure of ART.

Objective:To explore the relationship between the childhood trauma and neruocognition in patients with schizophrenia.Methods:Sixty-two patients with schizophrenic were selected from Anhui mental health center, and sixty-three community health controls were selected. All subjects were assessed with the childhood trauma questionnaire (CTQ), Wisconsin card sorting Test (WCST), attention network test (ANT), verbal fluency test (VFT) and digit span test (DST). SPSS 17.0 was used for statistical analysis. t-test was used to compare the measurement data of normal distribution and Mann-Whitney U test was used to compare the measurement data of non-normal distribution. Spearman correlation analysis was used to analyze the relationship between CTQ score and cognitive function score. Results:Compared with health controls(34.00(30.00, 37.00), 6.00 (5.00, 7.00), 5.00(5.00, 5.00), 5.00(5.00, 5.00), 9.00(6.00, 11.00), 7.00(6.00, 10.00)), the total score of CTQ, subscores of emotional abuse, physical abuse, sexual abuse, emotional neglect and physical neglect in patients with schizophrenia were significantly increased (48.50(37.75, 57.00), 9.00(6.00, 12.25), 7.00(5.00, 9.25), 5.50(5.00, 7.25), 13.00 (9.00, 16.25), 11.00(8.00, 13.00)) ( Z=-4.781--6.724, all P<0.01). Compared with the control group, the number of WCST classification completed in the patient group was lower, while the number of wrong answers, continuous answers and persistent errors increased ( Z=-5.655--6.060, all P< 0.01). The correct rate of ant decreased, but the reaction time increased ( Z=-5.796, -6.094, all P< 0.01). VFT and DST scores were decreased ( Z=-3.492--8.499, both P< 0.01). In patients with schizophrenia, CTQ sexual abuse subscore were negatively correlated with completed categories scores ( r=-0.384) and positively correlated with total errors ( r=0.360), perseverative responses( r=0.394) and perseverative errors ( r=0.381) on WCST(all P<0.01). CTQ physical neglect scores were negatively correlated with the ANT correct ratio( r=-0.400) and conflict resolution( r=-0.417) (all P<0.01). CTQ emotional neglect scores were negatively correlated with VFT scores( r=-0.345) ( P<0.01). The significant associations remained after controlling for age, education and PANSS scores. Conclusion:Patients with schizophrenia experience more traumatic events in their early years and have extensive cognitive defects. The childhood trauma has negative effects on cognitive flexibility, attention, memory and speech function in patients with schizophrenia.However, the positive correlation between childhood trauma and executive conflict of attention network needs to be further verified and explored.
