BACKGROUND: At present, the internationally public recognition of childhood trauma questionnaire is the authorized version of Bernstein,American psychologist, in 1998.OBJECTIVE: To set up the scale of Chinese version of childhood trauma questionnaire with 28 items and analyze its reliability and validity.DESIGN: Community investigation was designed.SETTING: Mental Health Institute, Xiangya Second Hospital, Central South University.PARTICIPANTS: Totally 441 students from 8 classes were randomized from a countryside middle school of a city in Henan in October 2004.METHODS: A total of 441 students were measured with childhood trauma questionnaire and 93 of them were re-measured 2 months later. Childhood trauma questionnaire included 28 items and divided into 5 subscales,named emotional abuse, physical abuse, sexual abuse, emotional neglect and physical neglect. Five grades were adopted in each item, named 1 score: never; 2 scores: occasionally; 3 scores: sometimes; 4 scores: often;and 5 scores: always. Every subscale was varied from 5 to 25 scores, and the total results were in the range from 25 to 125 scores. It was to analyze the internal identical property, reliability of re-measuring, average correlation coefficient among items and correlation coefficient between total score and every subscale. And the analysis was carried on validation factors. MAIN OUTCOME MEASURES: Homogeneity reliability, re-measuring reliability and validity, absolute fit index, relative fit index and parsimony index of childhood trauma questionnaire were involved.RESULTS: Totally 441 pieces of questionnaire were distributed on the spot and 435 pieces of questionnaire with integral and regular answers were collected. Totally 93 pieces of questionnaire were delivered for the second evaluation 2 months later and 93 pieces with regular answers were collected. All of those were used for the evaluation of re-measuring reliability of such measuring table. ① Cronbach α coefficient was 0.64 in Chinese version of childhood trauma questionnaire of and re-measuring reliability was 0.75. Cronbach αcoefficient of every subscale was varied from 0. 16 to 0.65 and re-measuring reliability was in the range from 0.27 to 0.73. The correlation coefficient among items was varied from -0.20 to 0. 44; ②The correlation coefficient between total score and every subscale was varied from 0. 36 to 0.68 and the correlation coefficient among subscales was from-0.01 to 0.39; ③ Indexes of validation factor analysis:The load coefficient of physical neglect was varied from 0.09 to 0. 64 and that in 2 items was less than 0.20. Multiple correlation coefficient was varied from-0. 20 to 0. 82, X2/df was 2.48 and root mean square error of appr0ximation(RMSEA) was 0.06. Added indexes: IFI (0. 76), CFI (0.75) and TLI (0.72) .Parsimony index: PNFI (0.58) and PCFI (0. 67).CONCLUSION: Chinese version of childhood trauma questionnaire provides better reliability and validity. According to validation analysis, except physical neglect, every index tallies with psychometric standards. The results of analysis on normative pathways are satisfactory, which explains that the subscales of such measuring model provide good matching property and conception validity.

Objective To compare the efficacy of amisulpride and other SGAs in treating the negative symptoms of Schizophrenia.Methods The randomized controlled trials (RCTs) about Schizophrenia treated with amisulpride and other SGAs from Jan 1995 to Mar 2013 were searched in The Pubmed,EMbase,Cochrane Library,WanFang Data,CNKI and VIP.Two reviewers independently screened the literatures,extracted the data,and evaluated the methodological quality.Than meta-analyses were conducted by using RevMan 5.1 and Stata 12.0 software.Results The totall3 RCTs were included.Among the 1814 patients involved.The results of meta-analyses showed that the score of PANSS-N was no significant differences between two groups (MD =-0.33,95％ CI:(-0.87,0.21),Z =1.20,P =0.23) ; and the score of SANS was no significant differences between two groups (MD =-0.21,95％ CI:(-1.51,1.50),Z =0.31,P =0.76).The side effects were more in other SGAs group than those in amisulpride group.Conclusion Amisulpride is as effective as other SGAs for the treatment of schizophrenia with predominantly negative symptoms,and it has more advantage than other SGAs in safety.

Objective To evaluate the effect of theta burst stimulation( TBS) paradigm of repetitive tran?scranial magnetic stimulation ( rTMS ) on the treatment of schizophrenia through assessing executive function. Methods 60 patients met with DSM?4 and ICD?10 for schizophrenia disorders criteria were enrolled in this study. The group was divided into theta burst stimulation group(research group, n=30) and sham intervention group ( control group, n=30) . The research group and control group were assessed with the Wisconsin card sorting test (WCST) and the go/no?go task by event?related potential(ERPs) before and after 4 weeks treatment. Each test results of all groups before and after treatment were compared with each other respectively. Results Regarding the WCST test,compared with the baseline,the post?rTMS state of the TBS group showed a decrease in the error selec?tion percentage((59.8±14.7)%),the preservative error number(55.3±18.0) and the preservative error percentage (71.3±12.6)%,but the percentage of conceptual level(71.3±12.6)% increased in the TBS group(P<0.05). Re?garding the go/no?go task by ERPs,compared with the baseline,the post?rTMS statet of the TBS group showed an increase in the no?go P3 amplitude(P<0.05 or 0.01) . After intervention,the score of WCST test and the no?go P3 amplitude were significant differences in TBS group compared with same rTMS group(P>0.05).Conclusions The?ta burst stimulation paradigm of rTMS can improve the executive function in schizophrenic patients.

Objective To explore the effect of theta burst stimulation (TBS) paradigm of repetitive transcranial magnetic stimulation (rT-MS) on executive function in patients with chronic schizophrenia. Methods 60 patients meeting DSM-IV for chronic schizophrenia disor-ders criteria were enrolled. They were randomly divided into TBS group (n=30) and sham intervention group (n=30). They were assessed with digit span performance, space span performance and Wisconsin Card Sorting Test (WCST) before and 4 weeks after intervention. Re-sults After intervention, the forward score of digit span performance, the total score and forward score of space span performance increased (P<0.05), the error selection percentage, the error selection number and the percentage of error number of WCST decreased, the percentage of conceptual level of WCST increased (P<0.05) in the TBS group. However, there was no significant difference in the digit span perfor-mance, space span performance and WSCT in the sham intervention group (P>0.05). There was significant difference in all the items be-tween 2 groups after intervention (P<0.05). Conclusion TBS paradigm of rTMS could improve the executive function in schizophrenic pa-tients.

Fhx/P25 in silkworm, Bombyx mori, one of the main components of silk fibroin, is presumed in previous reports to be expressed exclusively in the posterior silk gland (PSG) of the animal with strict territorial and developmental specificities. On the basis of a large-scale analysis ofthe silkworm EST data, it was found that Fhx/P25 gene is transcribed not only in the posterior silk gland, but in the ovary and in other tissues of the larvae at day 3 of the fifth-instar as well and that this gene has distinct transcription start sites (TSSs) in the posterior silk gland and the ovary. The TSS in the ovary is located about 115 bp upstream sequence of that in the posterior silk gland. Subsequent RT-PCR, FQ-PCR and sequencing have verified the validity of this presumption. In addition, alternative splicing is predicted in pre-mRNA of Fhx/P25 gene and confirmed by RT-PCR. In conclusion, Fhx/P25 gene is not a gene with strictly tissue-specific transcription.Complicated regulation mechanisms may exist for its transcription and expression and it may have other functions to perform.

Objective To explore the gray matter changes in aggressive patients with schizophrenia,and the relationship between the gray matter and aggression in patients.Methods Eighteen aggressive patients with schizophrenia (SZ1),18 age-and gender-matched un-aggressive patients with schizophrenia (SZ2) and 18 normal controls (NC) were enrolled in the study.Then a 3.0 T magnetic resonance imaging (MRI) scan was conducted for each participant.The voxel-based morphometry (VBM) approach and the Chinese version of Buss & Perry aggression questionnaire (B&P) were used to explore imaging data and to assess the aggression,respectively.Results Compared with NC,patients with schizophrenia showed changes in gray matter volume (GMV) in the frontal,temporal and the occipital lobes (P＜0.05,AlphaSim corrected).Compared with SZ2,SZ1 showed increased GMV in the right supramarginal gyrus,right postcentral gyms,bilateral insula and orbito-frontal gyri (P＜0.05,AlphaSim corrected).The GMV of the right insula,right postcentral gyms and right supramarginal grus were positively associated with B&P scores in patients with schizophrenia (P＜0.01,AlphaSim corrected),respectively.Conclusions These preliminary findings support that the aggression in schizophrenia is associated with GMV changes of brain regions in patients with schizophrenia.The right postcentral gyrus,the right insula and the right supramarginal gyrus may be involved in the neural mechanism of aggression in schizophrenia.

BACKGROUND: The Childhood Experience of Care and Abuse Questionnaire (CECA.Q) compiled by the Institute of Psychiatry, University of London, has been verified to have good reliability and validity in the assessment of foreign community adults and patients with affective disorder,but the application of CECA.Q in China still needs verification of reliability and validity in various population.OBJECTIVE: To analyze the reliability and validity of CECA.Q in community population.DESIGN: The subjects were randomized selected; the principle for the analysis of scale reliability and validity was followed.SETTING: Mental Health Institute of Central South University.PARTICIPANTS: From September 2003 to February 2004, 608 adults were selected from two communities of Hunan Changsha city and Henan Xinxiang city as the common community population group, totally 608scales of CECA.Q were sent out, 8 invalid ones were excluded, and finally 600 subjects finished the investigation. Sixty adult inpatients with depressive disease were randomly selected from Henan Provincial Psychiatric Hospital as the depression group.METHODS: The common community population and patients with depressive disease were investigated with CECA.Q, which was a self-rating scale mainly to retrospectively survey whether the adults had suffered from physical, sexual or mental abuse in their childhood, and the mental abuse had two factors of antipathy and neglect, and each included 8 items. The answers for the items were quantified into 5 grades. The subjects evaluated whether their parents had given any abuse to them; the higher the score was, the greater the mental abuse they suffered. Of the community population, 40 cases were the positive samples with the history of physical and sexual abuse in childhood evaluated by CECA.Q, and they were then assessed with Bifulco provided childhood experience of care and abuse (CECA) together with 40 cases randomly selected from 560 samples with negative evaluation. A total of 100 cases in the community population were also evaluated with Zung self-rating depression scale (SDS), besides, 30 cases were retested with CECA.Q at 2 weeks after the first evaluation.MAIN OUTCOME MEASURES: The internal consistency, test-retest reliability, contents and criterion validity of CECA.Q were analyzed. RESULTS: Of the community population, 8 invalid questionnaires were excluded, and the other 600 cases entered the statistical analysis. ① Testretest reliability of CECA.Q: The Cronbach α coefficient for the mental abuse section was 0.87 (0.85 for maternal one, 0.83 for paternal one); including that of antipathy factor was 0.84 (0.80 for maternal one, 0.81 for paternal one), and that of neglect factor was 0.85 (0.84 for maternal one,.83 for paternal one. The test-retest reliability coefficient for mental abuse as 0.83 (0.81 for maternal one, 082 for paternal one), including that of antipathy was 0.81 (0.82 for maternal one, 0.70 for paternal one), and that f neglect was 0.79 (0.78 for maternal one, 0.75 for paternal one). The twice evaluations of physical and sexual abuse had good consistency (Kappa=0.78). ② Criterion validity of CECA.Q: The correlation coefficients of mental abuse, antipathy and neglect factors in CECA.Q with Zung SDS were 0.58, 0.55 and 0.60 respectively (P＜0.01). CECA.Q and CECA had good consistency in evaluating history of physical and sexual abuse, and the score of mental abuse in the depressive patients was higher than that in community population (P＜0.05).CONCLUSION: The CECA.Q shows acceptable reliability and validity in community population, and can be used as a self-rating measure for childhood abuse experience in China.
