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 evaluate the value of gemstone spectral imaging (GSI)and multi artifact reduction system(MARs)in re-ducing metallic implants artifacts,and find the best monochromatic images.Methods Twenty-one patients with metal implants in our hospital receievd GSI examination ,MARS reconstruction and polychromatic images(140 kVp).Eleven groups of monochromatic and MARS images were obtained from 40 keV to 140 keV every interval of 10 keV by the special GSI viewer ,respetively.Subjective image quality of two methods were assessed by 3 radiologists in consensus.For every patient one group monochromatic images and blend enery images were selected two heaviest artifacts level and no artifacts level,the CT value and the standard deviations(SD)value of the region of interest(ROI)were meatured of artifacts.Contrast-to-noise ratio(CNR)and artifacts index(AI)were also caculated and were analyzed with paired-t test.Results There was significant statistical differences of CNR between energy spectral images and blend energy images in energy level of 40 to 120 keV(P <0.05),while there was no difference in energy level of 130 to 140 keV (P >0.05),and the optimal CNR was acquired at the energy level of 70 keV(CNR=8.75±3.28).The value of AI for two mehtods has no difference in energy level scope 40 to 60 keV(P >0.05),there was significant statistical differences of AI between energy spectral images and blend energy images in energy level of 70 to 140 keV(P <0.05),and the lowest of AI(AI=26.95±9.64)was ac-quired at 1 10 keV images.Conclusion The energy spectral CT possess superiority in decreasing the artifacts and will provide high image quality in the metal implants.Gemstone spectral CT has great significance for postoperative patients with metal implants in imaging diagnosis.

Objective To study current situations of occupational burnout and humanistic care ability of the nurses in our hospital and explore the relationship between them. Method Nursing burnout scale (NBS) and caring ability inventory(CAI) were adopted in the investigation among 542 nurses in our hospital. Results The total score on the nursing burnout of the nurses of my hospital was 96 to 214, with an average of (155.04 ± 17.01). The burnout among 245 of them (45.20%) was in mild to moderate degree and that among 155 of them (28.60%) in a severe level. The score on humanistic care ability was 94 to 253 with an average of (178.14 ± 23.66). The ability among 46.31%of them was at a middle level and that among 25.46%of them at a low level. The occupational burnout of the nurses was negatively correlated with their humanistic care ability as well as with its three dimensions of cognition, courage and patience (P<0.01). Conclusions The occupational burnout can be alleviated by reducing the pressure in their caregiving practice. Their humanistic care ability can be enhanced by improving humanistic care nursing education and bettering humanistic care system.

PURPOSE To investigate the application of CLSM in tumor pathology with the three dimensional reconstruction by confocal laser scanning microscopy in routine pathologic specimens of HCC, METHODS 30 ?m thick sections were cut from the paraffin-embedded tissues of HCC. hyperplasia and normal liver, stained with the DNA fluorescent probe YOYO-1 iodide and examined by CLSM to collect optical sections and 3D reconstructed images. RESULTS HCC displayed chaotic arrangement of carcinoma cell nuclei, marked pleomorphism. indented and irregular nuclear surface, and irregular and coarse chromatin texture. CONCLUSION The serial optical tomograms of CLSM can be used to create 3D reconstruction of cancer cells. Such 3D impressions might be helpful or even essential in arriving at an exact diagnosis

Objective:To understand outcome of heroin addicts after abstinence and analyze the factors related to relapse. Methods:A follow-up of 149 heroin addicts in a correction camp was carried out at 6th months after their discharge. Demographic characteristics, clinical features, addiction severity and psychiatric comorbidity were compared between those who relapsed and those who remained abstinent. Results: 22.8% of the subjects were abstinent, 46.3% relapsed, 29.5% in probation or in treatment,1.3% died. Relapse was related to the presence of drug addiction in family members, lack of abstinence intention, antisocial personality disorder, lack of rehabilitation therapy, intravenous heroin use and ASI scores in heroin abuse, composite family/social and legal factors. Conclusion:The outcome of heroin dependence after correction was poor. Relapse was related to family environment, abstinence intention, the heroin addiction severity,antisocial personality disorder.

Objective To study the correlation between the rabbit glucocorticoid receptor(GR) and steroid-induced glaucoma(SIG).Methods The GR binding in peripheral blood leukocytes and plasma cortisol were measured in 15 adults pigmented rabbits on the first day of experiment, 0.5mg dexamethasone was injected in the right eyes of each rabbit once every 2 days, totally 15 times for 30 days. Right eyes intraocular pressure(IOP) and aqueous outflow facility were measured every week, the relation between GR, plasma cortisol, IOP and aqueous outflow facility(C) was analyzed. Results After the experiment the IOP increased by 0.67kPa±0.49kPa(P<0.01),C decreased by 0.08±0.11(P<0.01).GR may closely be related to IOP and C(r=0.56,P<0.025; r=0.60,P<0.01).Plasma cortisol was independent of IOP and C(r=0.27, P>0.05;r=0.34,P>0.05).Conclusion The level of GR has positive correlation with the sensitivity of tissue of eye to glucocorticoid.
