Objective To explore the correlations of adult attachment with interpersonal conflict resolu-tions styles and differences between soldiers and employees. Methods Relationship questionnaire (RQ),experi-ence in close relationships (ECR),and Rahim handling interpersonal conflict inventory (ROCI-II) were adminis-tered to 543 employees from different enterprises in Beijing and Liaoning province and 701 soldiers. Results The results suggested the distribution of adult attachment style between soldiers and employees were significantly differ-ent. Compared with employees, there were higher dismissing hat lower secure rate in soldier sample. On handling interpersonal conflict strategy indices, such as integrating, avoiding, dominating and obliging but not compromising (t_((1120))=1.97, P<0.05), there were no significant differences between soldiers and employees. Only on in-tegrating, there were significant ditterenees among four adult attachment styles (F_((3,1009))=10.18, P<0.001).Attachment avoidance had a significantly negative correlation with integrating, obliging and compromising (r=-0.31,-0.11,-0.13 respectively), while attachment anxiety had moderate but significant correlations with a-voiding, dominating and obliging and compromising (r=0. 16,0.35, 0.35, 0.39, 0.30 respectively). Conclu-sion Adult attachment is closely related to handling interpersonal conflict strategies, and there was difference on compromising between soldiers and employees.

OBJECTIVETo pool the data of studies about anticoagulation in non-massive pulmonary thromboembolism (PTE) and evaluate the efficacy and safety of low molecular weight heparin (LMWH) and unfractionated heparin (UFH) as the initial treatment.

METHODSMEDLINE CD-ROM from January 1966 to August 2003 and CBM CD-ROM from January 1978 to August 2003 were chosen for searching the randomized clinical trials (RCTs) that compared the efficacy or safety of LMWH and UFH in non-massive PTE. A meta-analysis was employed to evaluate the results of these two therapies.

RESULTSFive RCTs including 999 cases were analyzed. Compared with UFH, the combined odds ratio (OR) of LMWH in treating PTE was as follows: (1) The total OR of mortality of PTE patients treated with LMWH was 0.81 (95%CI 0.36-1.81, P > 0.05); (2) The total OR of recurrence of venous thromboembolism (VTE) in PTE patients treated with LMWH was 0.37 (95%CI 0.14-1.00, P=0.05); (3) The total OR of bleeding in LMWH was 0.47 (95%CI 0.16-1.39, P > 0.05);(4) The total OR of heparin-induced thrombocytopenia (HIT) in LMWH was 0.66 (95%CI 0.06-6.92, P > 0.05).

CONCLUSIONSLMWH and UFH can reduce the mortality and recurrence of VTE in patients with PTE in the same degree. The risk of major bleeding was similar in the two treatment groups. Initial subcutaneous therapy with the LMWH appeared to be as effective and safe as intravenous UFH in the initial treatment of PTE.

OBJECTIVEThis paper aims to investigate the anti-tumor mechanism of inactivated Sendai virus (Hemagglutinating virus of Japan envelope, HVJ-E) for murine melanoma (B16F10).

METHODSThe murine dendritic cells (DCs) were treated with HVJ-E, and then the cytokines secreted from DCs and costimulation-related molecules on DCs were measured. Meanwhile, the expression of β-catenin in HVJ-E treated murine melanoma cells was detected. In addition, HVJ-E was intratumorally injected into the melanoma on C57BL/6 mice, and the immune cells, CTL response and tumor volume were analyzed.

RESULTSHVJ-E injected into B16F10 melanoma obviously inhibited the growth of the tumor and prolonged the survival time of the tumor-bearing mice. Profiles of cytokines secreted by dendritic cells (DCs) after HVJ-E stimulation showed that the number of cytokines released was significantly higher than that elicited by PBS (1P<0.05). The co-stimulation-related molecules on DCs were comparable to those stimulated by LPS. Immunohistochemical examinations demonstrated the repression of β-catenin in B16F10 melanoma cells after HVJ-E treatment. Meanwhile, real-time reverse transcription PCR revealed that HVJ-E induced a remarkable infiltration of CD11c positive cells, chemokine ligand 10 (CXCL10) molecules, interleukin-2 (IL-2) molecule, CD4(+) and CD8(+) T cells into HVJ-E injected tumors. Furthermore, the mRNA expression level of β-catenin in the HVJ-E injected tumors was also down-regulated. In addition, B16F10-specific CTLs were induced significantly after HVJ-E was injected into the tumor-bearing mice.

CONCLUSIONThis is the first report to show the effective inhibition of melanoma tumors by HVJ-E alone and the mechanism through which it induces antitumor immune responses and regulates important signal pathways for melanoma invasion. Therefore, HVJ-E shows its prospect as a novel therapeutic for melanoma therapy.

Objective To study the expression change of pro-brain natriuretic peptide (proBNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) in sudden death of coronary atherosclerotic heart disease,and to explore its application in forensic diagnosis.Methods Myocardial and blood samples were collected from normal control group,sudden death of coronary atherosclerotic heart disease group and single coronary stenosis group (20 cases in each group).The expression of proBNP in myocardial samples were detected by immunohistochemical staining and Western blotting,and that of BNP mRNA were detected by reverse transcription PCR (RT-PCR).The content of NT-proBNP in plasma were detected by ELISA.Results Immunohistochemical staining showed positive expression of proBNP in both sudden death of coronary atherosclerotic heart disease group and single coronary stenosis group.There was no positive expression in normal control group.For sudden death of coronary atherosclerotic heart disease group and single coronary stenosis group,the relative expression of proBNP protein and BNP mRNA in myocardial tissue and the NT-proBNP content in plasma were higher than that of normal control group (P＜0.05).The NT-proBNP content in plasma of sudden death of coronary atherosclerotic heart disease group was higher than that of single coronary stenosis group (P＜0.05).Conclusion In myocardial ischemia condition,the higher expression of proBNP in cardiac muscle cell shows that the detection of NT-proBNP in plasma can be useful to differentially diagnose the degree of coronary atherosclerotic heart disease and determine whether the sudden death due to coronary atherosclerotic heart disease.

Objective To examine the impact of pregnancy termination before 28 weeks of gestation on the overall prevalence of neural tube defects (NTDs).Methods Data collected during the period of 2004 and 2010 from a birth defects surveillance system in Pingding county and Talgu county of Shanxi province were used.Number of births ≥28 weeks of gestation and number of cases with major birth defects among the births were collected.Terminations of pregnancies before 28 weeks of gestation due to prenatal diagnosis were also collected.The total prevalence of neural tube defects,prevalence before 28 weeks of gestation,and prevalenee of ≥28 weeks gestation were calculated using the total number of pregnancies of ≥28 weeks of gestation as denominator.The prevalence data were compared to examine the impact of pregnancy termination on the total prevalence.The proportions of pregnancy terminations before 28 weeks of gestation due to prenatal diagnosis of an NTD against the total number of NTD cases were also calculated.Results During 2004-2010,52 366 births were recorded,and 485 NTD cases were ascertained.The overall prevalence of NTDs was 92.6 per 10 000 births,with prevalence of ＜28 weeks gestation due to pregnancy terminations as 60.9 per 10 000 births,while the prevalence of ≥28 weeks of gestation was 31.7 per 10 000 births.NTD prevalence of ≥28 weeks gestation was 66.0％ lower than the total NTD prevalence.In the last two years,the proportion of NTDs ascertained ≥28 weeks gestation accounted for about 40.0％ of the total NTD cases.Conclusion A birth-defect-surveillance program that covered only tregnancies ≥28 weeks of gestation resulted in a severe underestimation of the total birth prevalence of NTDs,especially for anencephaly.We would recommend that the current national birth defects surveillance system should include pregnancy terminations before 28 weeks of gestation and the calculation of total NTD prevalence should also include these cases into the numerator,so as to better estimate true population NTD prevalence,upon which the related public health policy is based.

Background: It is well-established that serum testosterone in men decreases with age, yet the underlying mechanism of this change remains elusive. Methods: The expression patterns of Fancd2 opposite-strand (Fancd2os) in BALB/c male mice and testicular tissue derived cell lines (GC-1, GC-2, TM3, and TM4) were assessed using real-time polymerase chain reaction (RT-PCR), Western blot and immunofluorescence. The Fancd2os-overexpressing or knockdown TM3 cells were constructed by infecting them with lentivirus particles and were used to evaluated the function of Fancd2os. The testosterone production was measured using enzyme linked immunosorbent assay (ELISA) and the steroidogenic enzymes such as steroidogenic acute regulatory protein (StAR), P450 cholesterol side-chain cleavage (P450scc), and 3β-hydroxysteroid dehydrogenase (3β-HSD) were analysed using RT-PCR. The apoptosis of TM3 cells induced by ultraviolet light or testicular tissues was detected using flow cytometry, Western blot or dUTP-biotin nick end labeling (TUNEL) assays. Pearson correlation analysis was used to assess the correlation between the Fancd2os expression and TUNEL-positive staining in mouse testicular Leydig cells. Results: The Fancd2os protein was predominantly expressed in mouse testicular Leydig cells and its expression increased with age. Fancd2os overexpression inhibited testosterone levels in TM3 Leydig cells, whereas knockdown of Fancd2os elevated testosterone production. Fancd2os overexpression downregulated the levels of StAR, P450scc and 3β-HSD, while Fancd2os knockdown reversed this effect. Fancd2os overexpression promoted ultraviolet light-induced apoptosis of TM3 cells. In contrast, Fancd2os knockdown restrained apoptosis in TM3 cells. In vivo assays revealed that higher Fancd2os levels and mouse age were associated with increased apoptosis in Leydig cells and decreased serum testosterone levels. Pearson correlation analysis exhibited a strong positive correlation between the expression of Fancd2os and TUNEL-positive staining in mouse testicular Leydig cells. Conclusion Our findings suggest that Fancd2os regulates testosterone synthesis via both steroidogenic enzymes and the apoptotic pathway.
