BACKGROUND: Personality obstacle is a special type of psychopathy. Since it can reflect personal psychological traits, such as emotion, cognition, behavior mode and the ways one gets along with others, it may lead to meaningful functional impairments and psychological pains if they obviously deviate the normal range, resulting in functional malajustment to society, occupation, social ethics, rules and law. Therefore it deserves further investigation with respect to its criminological significance.OBJECTIVE: To investigate the influence of personality traits, age, educational degree, and marriage state before serving the sentence on criminal behavior of female offenders.DESIGN: A retrospective and control study based on patients.SETTING: Center of psychological sanitary in a hospital of a university.PARTICIPANTS: This study was carried out in the Psychological Sanitary Center of the First Affiliated Hospital of Chongqing Medical College between April 2004 and May 2004. Totally 223 female offenders who incarcerated in Chongqing Female prison were selected. Inclusion criteria: All participants aged from 18 to 60 years old and received above elementary school education. Exclusion criteria: Those who have definite body ailments or psychopaths. Finally totally 204 valid questionnaires were collected from female offenders who were then divided into violent criminal group( n = 120) and non-violent criminal group ( n = 84).METHODS: Totally 223 female offenders who incarcerated in Chongqing Female Prison were asked to fill personality diagnostic questionnaires (PDQ-R), Esonk' personality questionnaires(EPQ), and symptom self-rating chart(SCL-90). Finally totally 204 effective questionnaires were collected for statistical analysis with SAS software.MAIN OUTCOME MEASURES: Comparison of scores for three questionnaires between the two groups; relationship between general condition(age,educational degree and marriage state before incarceration) with the scores for the three questionnaires.RESULTS: The total score for PDQ-R was above 30 in both the two groups and without significant difference between them, ( P ＞ 0.05); the different results for EPQ between the two group was of statistical significance( P ＞ 0. 05); but the total scores for SCL-90 were markedly different between the two groups,( P ＜ 0.01 ); only "educational degree" was found positively correlated with "histrionic trait"; all items except "psychopathy" were close lined with the general state in EPQ questionnaires( P ＜ 0.05); "impulsion and the number of positive items" in SCL-90 were found related with the general condition( P＜ 0.05).CONCLUSION:All criminals have personality obstacle of different type and different degree, but the difference of personality traits between violent female offenders and non-violent female offenders was of no statistical significance.

Objective To investigate the suicide attitude and social support system among college students with suicidal attempts in Chongqing .Methods To randomly select 9 808 college students from 11 universities in Chongqing and administer a self-con-structed questionnaire“Suicide Attitude and Mental Health Status Questionnaire”for analyzing the suicide attitude and social sup-port system of college students with or without suicide attempts .Results The reporting rate of suicide attempts was 1 .7% .The college students with suicide attempts consider that suicide is not preventable ,suicide is not self-control ,for the positive attitude to-wards suicide ,and think that suicide can change the behavior of others .People without suicide attempts are more likely to discrimi-nate against suicide ,the attitude to suicide behavior is negative ,do not think suicide can change others behavior and acknowledge the social importance of suicide .Compared to student who did not report prior attempts ,suicide attempts had significantly lower scores in total score for social support ,actual social support provided ,subjective perception of social support and the utilization of social support .There is significant negative correlation between suicide do not preventive ,suicide do not self control ,positive attitude to-wards suicide and social support scores and scores of each dimension in the student with suicide attempts .The social importance of suicide with social support scores and the scores of each dimension has significant positive correlation .Conclusion College students with suicide attempts tended to be more sure about suicide ,their social support system was poorer .It reminds college educators and social relevant departments to strengthen the suicide knowledge education and improve college students'social support systems ,so that we can provide early intervention for high-risk students with suicide risk ,and prevent the occurrence of suicidal behavior .

OBJECTIVE:To discuss the effects of Rujieping capsule on estrogen receptor(ER) and progesteron receptor(PR) of pathological tissues in rats with hyperplasia of mammary glands.METHODS:The rats were injected i.m with Estradiol benzoate injection for 25 days followed by the injection of Progesterone injection i.m for 5 days to establish the model of hyperplasia of mammary glands.Which were treated with high and low doses of Rujieping capsule respectively for 30 days with tamoxifen as positive control.RESULTS:Both tamoxifen and high and low doses of Rujieping capsules could lessen the symptoms of red swelling of nipples or hyperplasia of mammary glands,lower the levels of E2 and PRL,enhance the level of progestone,lower the index of uterus,markedly reduce the number of layers of the ductal epithelial cells,reduce the levels of ER and PR in mammary glands,and suppress mammoplasia.CONCLUSION:Rujieping capsules is effective in the treatment of hyperplasia of mammary glands in rats by regulating the level of estrogen and improve pathomorphologic change of hyperplastic mammary glands.

OBJECTIVE:To study the immunoregularoty effect of Lappaconitine in S180 tumor-bearing mice.METHODS: Each mouse was inoculated hypodermically with S180 tumor cells and normal sodium suspension,24 hours later,all the mice were injected i.m.with Lappaconitine q.d for 10 consecutive days.The immune function of the S180 tumor-bearing mice was detected.RESULTS: In Lappaconitine-treated mice,serum IgG level was heightened significantly;the 2,4-DNFB-induced delayed type hypersensitivity was enhanced;the induction of transformation of lymphocytes into lymphoblast was achieved;the phagocytic function of reticuloendothelial system was enhanced significantly,and the immune function of red cells was promoted.CONCLUSION: Lappaconitine could inhibit the growth of S180 tumor cells and significantly enhance the cellular immune function of S180 tumor-bearing mice.

Objective To develop a Vocational Interest Scale of University Students which fits the contemporary current university students, and it could give directions to university students when they were choosing a vocation. Methods Taking Holland's theory as the guide and taking 65 items of Self-Directed Search (SDS) for reference, then adding 28 items which standed for contemporary current university students' ideas of vocational interest to develop original Vocational Interest Scale of University Students.

The reliability of the scale was very good, the Cronbach's coefficients and spit-half reliability were over 0.7. The factor analysis abstracted 7 factors and the total variance explained reached 45%. The factor analysis results indicated that the scale had a good structure.Conclusion This scale make vocational interest as measuring object and could be a useful tool to give directions to university students who are choosing some vocation.

The skin biopsy specimens from fifteen patients with Langerhans cell histiocytosis were studied. Thirteen out of fifteen cases were positive to S100 protein antibody and peanut agglutinin, but negative to Mac387 and lysozyme antibodies, and three cases were positive for CD1 antibody by immunohistochemistry. Birbeck granules were demonstrated in one of the three cases by electron microscopy. Ten cases were analysed by flow cytometry, six cases (60%) were aneuploid, DNA index was 1.38?0.32, proliferative index was 38.69%. These results showed that these pathognomonic histiocytes were of Langerhans cell origin and their potential malignancy could not be ruled out.

BACKGROUND: The oriented migration of bone marrow mesenchymal stem cells may depend on the interaction between local chemotactic factors and cellsurface receptors. However, which chemotactic factors may mediate the oriented migration of bone marrow mesenchymal stem cells towards the fracture site remains unclear. OBJECTIVE: To tag autologous bone marrow mesenchymal stem cells, evaluate its role in bone healing, and detect the highly expressed factors associated with migration of bone marrow mesenchymal stem cells in the microenvironment. METHODS: The fluorescence/chimeric C57BL/6 mouse models were established, then left shankbone fracture models were also produced. The percentages of green fluorescent protein positive cells to al cells at the fracture site and the percentage of osteoblasts differentiated from bone marrow mesenchymal stem cells to al the osteoblasts were detected at different time points. The role of bone marrow mesenchymal stem cells in the fracture repairing was evaluated. The levels of chemotactic factors protein expression at the fracture site in different time points were detected with immunohistochemistry technology. RESULTS AND CONCLUSION: The percentage of green fluorescent protein positive cells to al cells at the fracture site was (3.011±0.911)%, (9.031±0.145)%, (12.064±0.145)% at 1, 5, 14 days postoperatively; and osteoblasts differentiated from bone marrow mesenchymal stem cells accounted for 50% of al the osteoblasts. After fracture, the stromal cel derived factor-1, colony stimulating factor, hepatocyte growth factor, monocyte chemoattractant protein-1, and matrix metal oproteinases-9 were expressed to varying degrees in the microenvironment, while the expression of granulocyte colony-stimulating factor was negative. The expression of stromal cel derived factor-1 in the fracture microenvironment was the highest, mainly due to the migration of bone marrow mesenchymal stem cells. Experimental findings indicate that, autologous bone marrow mesenchymal stem cells participate in and play an important role in bone healing. The stromal cel derived factor-1 plays an important role in promoting bone marrow mesenchymal stem cells migration and promoting bone healing.
