The personality abnormality is a remarkable characteristic in schizophrenia. Some evidence to date indicated that there existed measurable scores of personality traits in schizophrenic patients, though the psychotic symptoms were concomitant. The psychotic symptoms were deemed to influence the assessment of personality traits in schizophrenia for the symptoms and personality abnormality were entangled tightly. Yet, it cannot exclude the personality pathology in the psychopathology of schizophrenia. Moreover, the personality abnormality was related to cognitive deficit, prognosis, and insight in schizophrenics. It was difficult to disentangle the relationship between personality psychopathology and schizophrenia. Spectrum, pathoplasty, and etiology model each could explain the relationship partially. An integrated viewpoint incorporating all three models was discussed. However, it needs further researches to investigate some important issues such as the physiological basis and psychological mechanism of the relationship, the influence of culture on personality assessment.

Background Based on prior research in the field, a preliminary questionnaire was created to compare the coping strategies of schizophrenic patients to those of non-ill community residents. Results of the comparison were subsequently used to develop a questionnaire suitable for use in schizophrenic patients.Methods Ninety-one of the 92 items in the preliminary questionnaire were identified from previous questionnaires, and one additional item was created based on information provided in individual interviews with schizophrenic patients. This questionnaire was administered to 315 community controls and 208 schizophrenic inpatients. Exploratory Factor Analyses to identify the factor structure of coping strategies were independently conducted for controls and patients. Based on these results, a revised 65-item instrument was developed and administered to a new group of 287 controls and 219 schizophrenic inpatients. Confirmatory Factor Analyses (CFA) using Linear Structural Relations (LISREL) were independently conducted for the two groups to confirm their respective factor structures.Results Six coping categories identified in normal controls were problem solving, avoidance, cognitive adjustment, emotional adjustment, seeking special support, and denial. Among schizophrenic patients, however,coping strategies of "seeking special support" and "denial" were not independent of the other four coping categories. Their items were distributed among the others. Results of CFA confirmed this four-category model of coping strategies for schizophrenic patients.Conclusions Coping categories employed by schizophrenic patients were different from those employed by normal community controls. Schizophrenic patients lacked the necessary flexibility of selecting appropriate coping strategies.

Objective:To analyze the prognostic factors in patients with metastatic breast cancer (MBC). Methods:A total of 205 patients with pretreated MBC were included in this study. These patients were admitted to the Tianjin Medical University Cancer Insti-tute&Hospital and had undergone radical surgery of breast cancer between January 2008 and December 2010. The clinicopathologic information of the patients was collected in this retrospective analysis. Results: The median overall survival of the patients was 32 months (1 month to 132 months). Luminal A, Luminal B, HER-2 overexpression, and triple-negative patients had a median overall sur-vival of 36 months (4 months to 132 months), 32 months (7 months to 122 months), 29 months (1 month to 85 months), and 24 months (1 month to 98 months), respectively. Univariate analysis showed that lymph node metastases, clinical stage, molecular type, visceral disease, first multiple metastatic sites, and shorter metastasis-free interval were significantly associated with poor outcomes. In multivar-iate analysis, lymph node metastases, clinical stage, molecular type, visceral metastasis, and the number of first metastatic sites were significant predictors of patient survival. Conclusion:Lymph node metastasis, clinical stage, triple-negative breast cancer, and visceral metastasis were used as independent poor prognostic indicators for survival in patients. Results of this study may assist physicians in evaluating the survival potential and determining the appropriate therapeutic strategy for MBC patients.

Objective To construct the recombinant RIP3 over-expressed plasmids and transfect them in breast cancer MCF7 cells, and identify the expression and localization of fusion protein, as well as its effect on the death way of MCF7 cells. Methods The expression levels of RIP3 mRNA in four breast cancer cell lines and normal mammary epithelial cells were detected by reverse transcription polymerase chain reaction (RT-PCR). The RIP 3 coding sequence was amplified by polymerase chain reaction and subcloned into mCherry vector to construct recombinant plasmids. The plasmids were transfected into MCF7 cells by lentivirus after DNA sequencing, then screened by basticidin (4 mg/L) for 1 week. The efficiencies of RIP3 expression were validated by Western blotting assay. The death way of mCherry-RIP3-MCF7 cells was observed under the treatment of TNF-αand Z-VAD-FMK. Results The lowest expression of RIP3 mRNA was found in MCF7 cells. The sequencing results validated the well recombinant plasmids. The expression of mCherry-RIP3 fusion pro-tein with a molecular weight of 85 ku was detected by Western blot assay. The mCherry-RIP3 expression enhanced the sensi-tivity of MCF7 cells to TNF-αand Z-VAD-FMK induced cell death. Conclusion The recombinant RIP3 over-expressed plasmids were successfully constructed, and the stable MCF7 cells with ectopic RIP3 transfection were obtained. The mCher-ry-RIP3 fusion protein was expressed in the cytoplasm and was conformed to mediate TNF-αinduced necroptosis.

Objectives:To explore the prevalence and correlates of attempted suicide among Beijing psycho-logical aids hotline callers,in order to provide knowledge of hotline-based suicide prevention.Methods:From De-cember 2002 to December 2008,all the effective callers who consulted themselves'psychological problem,by Bei-jing psychological aids hotline were interviewed by professional hotline operators during the consulting calling.Data of whether callers attempted suicidal behavior in 2 weeks prior to the calling,gender and other 5 demographic char-acteristics of callers were collected via hotline interview.A questionnaire including depression screening scale,com-mon psychiatric symptoms such as delusion,hallucination,etc.,a history of substance abuse or dependence,a histo-ry of suicidal behavior,having had acute or chronic life events,and severity of hopeless was used during hotline in-terview.Logistic regression model was used.Results:In 22 415 interviewed callers,362 (1.6%)callers (233 fe-males)reported that they attempted suicidal behavior in 2 weeks prior to the calling.After adjusted for demographic characteristics,prior suicidal behavior 2 weeks before calling (OR=4.43,95%CI:3.37-5.83),hopelessness (OR=2.01,95%CI:1.52-2.67),substance abuse (OR=1.97,95%CI:1.48 -2.62),acute negative life events (OR=1.94,95%CI:1.49-2.52),and severe depressive symptoms (OR=1.45,95%CI:1.08-1.95)were associatedwith attempted suicide among hotline callers.Conclusion:The rates of attempted suicide among hotline callers are probably high.Suicide prevention in hotline would shed light on improving coping skills for life events and sub-stance abuse problems for hotline callers.

Objective To Compare characteristics between the psychological aids hotline callers who had single attempted suicide and those callers who had repeated attempted suicide. Methods The analysis was conducted on the da?tabase of Beijing psychological aids hotline from Dec., 2002 to Dec., 2008. All the effective callers were consulted by pro?fessional hotline operators. During the calling, the callers were interviewed on their attempted suicides, depression and 11 correlates associated with caller's suicidal behaviors. Results Among 4519 callers who had attempted suicide, 2441 (54%) of them had attempted suicide once, and the other 2078 (46.0%) callers had repeated suicide attempts. After ad?justed for gender, age, and the other 4 demographic variables, history of being abused (OR=1.35, 95%CI: 1.08~1.67), afraid of being attack (OR=1.35, 95%CI: 1.01~1.59), relatives or associates with prior suicidal behavior history (OR=1.17, 95%CI: 1.001~1.36), hopelessness (OR=1.20, 95%CI: 1.02~1.40), and psychological treatment history (OR=0.73, 95%CI:0.62~0.86) were associated with repeated suicide among hotline callers. Conclusions To improve the effective?ness of hotline based suicide prevention, assessment of risk of repeated attempted suicide among the callers with a histo?ry of prior attempted suicide should focus on the history of being abused, afraid of being attack, hopelessness, relatives or associates with prior suicide history, and psychological treatment history.

Objective:To investigate the role of bone morphogenetic protein 2/7 heterodimer (BMP-2/7)in the osteogenesis of human adipose-derived stem cells (hASCs).Methods:hASCs were exposed to three different treatments in vitro:osteogenic medium with 1 50 μg/L BMP-2/7 (experimental group), osteogenic medium alone (OM group)and proliferation medium (PM group).After 1 ,4 and 7 days of osteogenic induction,the amount of cellular DNA was measured to investigate the cytotoxicity.After 7 and 1 4 days,alkaline phosphatase (ALP)staining and quantification were performed to test the activity of ALP.After 21 and 28 days,the calcification deposition was determined by Alizarin Red S (ARS)stai-ning and quantification.The expressions of the osteoblast-related genes were tested on days 1 ,4,7 and 1 4.In the in vivo study,6 nude mice were used and 4 groups were set and implanted subcutaneously into the back of nude mice:(1 )β-TCP scaffold only (scaffold control group );(2 )β-TCP scaffold with hASCs cultured by PMin vitro for 1 week (PMcontrol group);(3)β-TCP scaffold with hASCs cultured by OM in vitro for 1 week (OM control group);(4)β-TCP scaffold with hASCs cultured by OM with 1 50 μg/L BMP-2/7 in vitro for 1 week (test group).After 4 weeks of implantation,histological staining was performed to evaluate the in vivo osteogenesis of hASCs.Results:After induction for 1 day,there was no significant difference between the experimental group and the PM group on the cellular DNA con-tent (P>0.05 ).After 4 days,the cellular DNA content increased under the stimulation of BMP-2/7 (P<0.05).On day 7,there was no significant difference among the three groups (P>0.05).ALP ac-tivity was higher by the induction of BMP-2/7 than in OMalone and PM(P<0.05).More mineraliza-tion deposition and more expressions of osteoblast-related genes such as Runx2,ALP,COL-1 A1 and OC were determined in the experimental group at different time points (P<0.05).HE staining showed that, in the test group and OM control group,the extracellular matrix (ECM)with eosinophilic staining were observed around hASCs,and newly-formed bone-like tissues could be found in ECM around the scaffold materials.Moreover,compared with the OM control group,more bone-like tissues could be observed in ECMwith typical structure of bone tissue in the test group.Masson’s trichrome staining showed that more expression of collagen could be observed in ECM in the test group compared with the other groups.There was small amount of expression of collagen in the OM and PM control groups.No obvious positive results were found in the scaffold group.Conclusion:BMP-2/7 heterodimer plays a significant role in the osteo-genesis of hASCs and is able to enhance the osteogenic differentiation of hASCs in vitro and in vivo.

Objective:This study aimed to observe the synergistic effect of a new tumor vaccine combined with metronomic che-motherapy in vivo on breast cancer. This study was also conducted to investigate the mechanism of this combination. Methods:Balb/c mice inoculated with 4T1 mouse breast cancer cell were used as tumor models. High-mobility group nucleosome-binding protein 1 (HMGN1) gene was used to transfect 4T1 cell lines as cancer vaccines. After 4T1 cell was inoculated, the mice were randomized into four groups:normal saline (NS);metronomic gemcitabine (GEM) alone;cancer vaccine alone;and combination therapy group. Tumor growth and potential toxicities of these regimens were observed. The Foxp3 expression of regulatory T cells (Tregs) was detected by western blot and immunohistochemical staining. The microvessel density (MVD) of the tumor was also detected by immunohistochemi-cal staining. Results:The tumor volume of the mice was significantly lower in the combination group than in the MET group or cancer vaccine group (P<0.05). This result exhibited a higher significant difference than the tumor volume of the mice in the NS group (P<0.01). Foxp3 expression was significantly lower in the mice treated with GEM (combination or MET group). MVD was significantly lower in these two groups than in the cancer vaccine group or NS group (P<0.05). Furthermore, adverse reactions slightly occurred in each group. Conclusion: The combination of cancer vaccines and metronomic GEM is a very active and well-tolerated regimen for breast cancer in mice.

Objective To examine the different effects of impulsive and aggressive personality on college students' suicide attempt. Methods Four thousand nine hundred eighteen sophomores and juniors were selected according to the principle of cluster sampling from Beijing agricultural university and Beijing university of information science and tech?nology. Four thousand seven hundred ninety-seven of them completed the survey. Their impulsive and aggressive person?ality were evaluated by the Barratt Impulsiveness Scale-Chinese Versions (BIS-CV) and the Buss-Perry Aggression Questionnaire-Chinese Versions (AQ-CV). A self-made questionnaire were used to investigate suicidal idea and self-in?jury/suicidal behavior of college students. Results Among the sophomores and juniors, 18 participants had self-injury/suicidal behavior (3.75‰) and 1843 had suicidal idea (38.42%). Compared with the students who didn’t have self-inju?ry/suicidal behavior, those who once had self-injury/suicidal behavior had significantly higher BIS-CV score (P<0.01) and higher scores of non-planning and motor factors (P<0.05). They also had significantly higher score in AQ-CV and the factors of physical aggression, verbal aggression, anger, hostility and pointing to the self attacks (P<0.01). Conclu? sions The college students with self-injury/suicidal behavior have higher tendency in impulsive and aggressive personali?ty. Therefore, it is necessary to prevent suicide behavior, form high impulsive and aggressive intention and behavior.
