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.

This study was aimed to establish a method for quality control of Tibetan medicine Shi-Wei Xiao-Shi-San (SWXSS). Thin layer chromatography (TLC) was established for the qualitative determination. Cinnamal and piperine were determined by HPLC. The separation was performed on Phenomenex C18 column (4.6 mm × 250 mm, 5μm). The results showed that TLC can be used in the identification of pomegranate seed and Terminalia chebula. The linear ranges of cinnamal and piperine were within the range of 0.06-0.37μg and 0.05-0.33μg, respectively. And the standard line was Y=9.273 2×106X-2.348 2×105, r=0.999 8;Y=7.315×103X-3.857, r=1.000 0. It was concluded that the identification method was specific, accurate and practical, which can be applied in the quality control of SWXSS.

Objective To investigate the interseed dose attenuation for multiple 125I seeds.Methods Monte Carlo simulation was done by Geant 4 to investigate the dose distribution of single seed and multiple seeds.The results were compared with the dose calculation method from TG43-U1 and examined by experiments.Results The difference of single seed dose distribution between Monte Carlo method and line source model was ± 3％.The difference between Monte Carlo method and experiment result was ± 5％.The interseed dose attenuation of multiple seeds at the interesting points was 3.8％ to 13.2％ and the average interseed dose attenuation was 7.2％.The difference of experiment result and Monte Carlo result was less than 6％.Conclusions The interseed attenuation is about 7％ and the maximum value may be larger than 13％ for multiple seeds.The interseed dose attenuation may be larger in tissue.So it is not accurate to calculate the dose distribution by using TG43-U1.

Purpose To investigate the expression pattern and c1inicopatho1ogica1 significance of D2-40 in craniopharyngioma( CP). Methods Immunohistochemica1 method was used to assess D2-40 expression in 126 cases of craniopharyngioma. Statistic software was used to ana1yze the corre1ation between D2-40 expression and c1inicopatho1ogica1 features. Results The overa11 positive rate of D2-40 expression in 126 craniopharyngioma was 87. 30%. The rate of +, and  were 44. 44%( 56/126 ),37. 30%( 47/126 )and 5. 56%(7/126)respective1y. In adamantinomatous CPs,D2-40 expression was observed in epithe1ia1 components corresponding to the stratum intermedium,whi1e in papi11ary CPs,it was immuno-positive in basa1 ce11s. With the increasing of the existence of inf1amma-tion in tumor,D2-40 expression was up-regu1ated. Tumor ce11s were over-expressed for D2-40 in basa1 ce11s and stratum intermedium ce11s of the invasive frontier. D2-40 expression was higher in the invasive craniopharyngioma than in the non-invasive craniopharyngio-ma. In addition,D2-40 expression was higher in the recurrent craniopharyngioma than in the non-recurrent craniopharyngioma. There were no significant re1ationship between D2-40 expression and gender,and histo1ogica1 c1assification of tumors. Conclusions D2-40 expression is associated with the deve1opment of craniopharyngioma,which can 1ead to enhance the tumor ce11 invasion,and may be re-1ated to inf1ammation-re1ated mechanisms. D2-40 expression may be one of the recurrence factors in patients with craniopharyngioma.

Objective:To investigate the correlation of Mena protein expression with the invasion and metastasis of Mena SNPs with genetic susceptibility in gastric cancers (GC). Methods:A tissue microarray that simulates the invasion and metastasis process of GC was created, and immunohistochemistry was performed to detect the expression of Mena protein. The Mena gene 5 SNP loci geno-types of 188 healthy people and 389 GC patients were assayed using PCR-based LDR analysis. Results:The expression of Mena pro-tein in GC was significantly upregulated and greatly increased in the intestinal-type and mixed-type GC than that in the diffuse-type and was negatively related to the invasion and metastasis of GC. Patients with Mena overexpression had better prognosis. The frequen-cies of the A and G alleles, as well as the AA, AG, and GG genotypes, at the Mena SNP rs3795443 locus were significantly different be-tween patients with gastric carcinoma and the control groups (OR=2.1489,95%CI 1.4607~3.1613, P<0.01). The frequencies of these five Mena gene SNP loci were not significantly related with the survival of patients with gastric carcinoma. Conclusion:The upregula-tion of Mena expression is involved in maintaining the histological phenotype, invasion, metastasis, and prognosis of gastric adenocarci-noma. Individuals with GG and AG genotypes at the Mena rs3795443 locus have increased risk of gastric carcinoma, which suggests that screening for this genotype would be helpful in assessing the genetic susceptibility of gastric carcinoma.

Purpose To investigate the expression of Par3, Par6 and aPKC in gastric carcinoma and their significance. Method Ex-pression of Par3, Par6 and aPKC, by using immunohistochemistry, was detected in different sites of gastric carcinoma ( including the gastric carcinoma in gastric mucosa, the central area and the invasive front of gastric carcinoma) and the lymph node metastasis, using normal gastric mucosa as controls. Results Expression of Par3, Par6 and aPKC in different sites of gastric carcinoma was lower than in that of normal gastric mucosa (P<0. 01). Expression of Par3, Par6 and aPKC was obviously lower in gastric carcinoma with gastric phenotype than in that with intestinal phenotype and mixed phenotype of gastric carcinoma (P<0. 05, P<0. 01, P<0. 01);the rate of down-regulation of Par6 and aPKC in gastric carcinoma with invasion to ectoptygma and out of ectoptygma was obviously higher than that in gastric carcinoma which located at mucosa and under mucosa (P both<0. 01), and the rate of down-regulation of Par6 in gas-tric carcinoma with lymph node metastasis was obviously lower than that with no lymph node metastasis ( P>0. 05 ) . Conclusions The down-regulation expression of Par3, Par6 and aPKC may promote the carcinogenesis and progression of gastric carcinoma.

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.
