Objective: To observe the histological changes of lamina extema cranii at both the graft and donor areas after having been grafted in animal experiment. Methods; 4 mini pigs aged from 8 to 12 months were selected. Part of the outer table of skull (2.5 cm × 1.0 cm) was decorticated and was divided equally. Both were implanted on each side of the snouts of animals. 2 pigs were selected randomly and were killed 12 weeks postoperation. Each 1, 0 cm ×0. 5 cm specimen was harvested and histological study was performed. The other 2 animals were killed 24 weeks after operation. Gross inspection of the donor site was performed and histological study was done. Results; In the graft area; bone absorption was obvious 12 weeks postoperation, but bone matrix increased obviously at 24 weeks postoperation. Results of scanning electron microscope showed that interface between bone graft and recipient site was discernment and collagen type I was malaligned 12 weeks postoperation. Collagen fibers were in good order and good mineralization was found 24 weeks postoperation. In the donor area; small amounts of new bone formation could be seen and alignment of cemental line was chaotic 12 weeks postoperation. At 24 weeks, bone formation was obvious and alignment of haversian canal was regular. Scanning electron microscopy showed that structure of the tissue was uneven and disorder at 12 weeks postoperation. Collagen fibers were in good order and good mineralization was found 24 weeks postoperation. On gross view, raw surface of the donor site got complete healing, os-teanagenesis was incomplete and introcession could be observed in the local area. Conclusion; Histological remodeling of lamina exter-na cranii is complete at 24 weeks after having been grafted. The donor site can regenerate but morphologic introcession could be observed.

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 investigate the efficacy and safety of preoperative systemic chemotherapy combined with regional intraarterial chemoembolization in the treatment of locally advanced gastric cancer.Methods Clinical data of 158 patients of locally advanced gastric receiving neoadjuvant chemotherapy cancer from January 2008 to July 2012 were retrospectively analyzed.Patients were divided into two groups:those who received preoperative systemic chemotherapy plus regional intraarterial chemoembolization (group A,n =78) and those who received preoperative systemic chemotherapy (group B,n =80).Radical resection was perfomed after 3 to 4 weeks.Results The overall satisfactory rate was significantly higher (60％) in group A compared with 42％ in group B (x2 =6.136,P ＜0.05).The incidence rate of toxicity reaction (except nausea) and postoperative conplications such as anastomotic leakage,intestinal obstruction,poor wound healing,abdominal infection and pulmonary infection were all lower in group A than in group B (all P ＜ 0.05),while the incidence rate of nausea was higher in group A than in Group B (x2 =16.458,P ＜ 0.01).There was no perioperative mortality related to neoadjuvant therapy in two groups.Conclusions Preoperative systemic chemotherapy combined with regional intraarterial chemoembolization was associated with better efficacy,and fewer toxicity reactions and postoperative complications in the treatment of locally advanced gastric cancer.

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.
