Objective To understand the occurrence situation of negative life events in the past year among college students with suicidal ideation and to explore the correlation between negative life events and suicidal ideation. Methods The stratified and cluster sampling method was applied to conduct the questionnaire survey on 12 114 students from 11 universities in Chongqing City. The questionnaire of general demographic information was used to learn sociodemographic characteristics;the perspective on personal life questionnaire was applied to evaluate the suicidal ideation within recent 1 month and the self-designed life event scale was used to investigate the occurrence of negative life events in the past 1 year. Results The report rate of suicidal ideation within 1 month was 9.6%, the occurrence rate of short term suicidal ideation was increased with experiencing more negative life events. The x2 test showed that there was statistically significant difference in the proportion of suicidal ideation occurrence between college students experiencing 1 negative life event and those without experiencing the negative life event (x2 = 37.72,P<0.01) ;besides, the occurrence proportion of recent suicidal ideation had statistical difference between the college students with experiencing two or more negative life events and those without experiencing negative life event (x2 = 65.46,P<0.01). The multivariate Logistic regression analysis showed that the conflict with other family members (OR=0. 295,95%CI 0. 017-0. 571),abuse (OR=7. 295, 95%CI 6. 049-9. 701) were independentrisk factor for the recent suicidal ideation in college students. Conclusion Experiencing more negative life events, conflicting with other family members and abused by others have a correlation with the appearance of short term suicidal ideation in college students.

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.

BACKGROUND:The glial scar is a major obstacle to the regeneration of the central nervous system, which plays a physical and chemical barrier role to central nervous system regeneration. How to effectively inhibit glial scar formation and promote axonal regeneration has great significance. OBJECTIVE:To explore the effect of the immune response in the formation of the glial scar after spinal cord injury. METHODS:A computer-based online search was performed in the PubMed database and the CNKI database for the articles on the mechanisms of spinal cord injury, immune cel s and spinal cord injury as wel as the glial scar formation after spinal cord injury from January 1990 to January 2013. The key words were “spinal cord injury, immunity, glia scar”in Chinese and English. The languages of the articles were limited in Chinese and English. Final y, 72 articles were included for the further analysis according the inclusion criteria. RESULTS AND CONCLUSION: After spinal cord injury, the effect of autoimmune response in which stil been much debated. Studies showed that spinal cord injury can cause suppression of cel ular immunity and non-specific immune function, causing immune function decreasing. Monitoring immune indicators and improving immune function have great significance in promoting the ful rehabilitation of patients with spinal cord injury. Glial scar is the most important factor to prevent the repairing after spinal cord injury. Immune and inflammatory response is the main reason to secondary spinal cord injury. Degree of repair after spinal cord injury mainly depends on the protection of the residual neurons in order to keep them off secondary damage. However, autoimmune T cel s can protect the residual neurons, the specific effect of T lymphocytes in glial scar formation after spinal cord injury is stil unclear, and further exploration is needed.

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.
