Subject To explore the features of the abnormalities of the sex chromatin and the sex chromosome of the patients with mental disorders. Methods The sex chromatin in the cells of buccal mucous membrane of the 2 784 patients with mental disorders were examined by using a blinding and random way. The chromosome karyotypes in peripheral blood were further examined in those whose measure showed abnormal. The comparison group consisted of 1 069 normal persons.Results Compaired with the control group,the average frequency of Y chromatin in the male patients [(28.0±6.6)%] and the average frequency of X chromatin in the female patients [(22.3±8.0)%] rose significantly ; the average frequency of X chromatin in the female patients of the schizophrenia subgroup and the affective disorder subgroup were higher than that of neurosis and psychogenic mental disorder subgroup. X chromatins of eight male patients were positive and the karyotypes of the abnormal X chromosome were 47,XXY in 3 cases and 47,XXY/46,XY in 5 cases, the rate of 47,XXY was 7.7 , it rose significantly to the control group. X chromatin of two female patients were negative and the karyotypes of the abnormal X chromosome was 45,X/46,XX, the rate of 45,X was 1.2 ; one female patient had double X chromatin and the karyotypes of the abnormal X chromosome was 47,XXX/46,XX,there is no abnormal sex chromatin and sex chromosome in the control group.Conclusions The higher rate of the sex chromatin might be closely associated with the tendency of heredity of mental disorders , and the rate of the lacking X chromosome in females and the increasing X chromosome in males rise in the patients with mental disorders.

Objective To understand the job stressors, coping style and general self-efficacy of emergency nurses and relationship of them. Methods A cross-sectional study involving 83 emergency nurses were conducted through the Chinese Nurses′ Job Stress Sources Scale, Trait Coping Style Questionnaire, General Self-efficacy Scale. Results Job stress among nurses in emergency department was caused by heavy workloads and time distribution (2.88±0.82), issue of patient care (2.78±0.59). The score of emergency nurses′coping propensity was 3.77, indicating more use of positive coping. Negative coping scored higher than the norm (26.99±4.76 vs.21.25±7.41), the difference was significant (t=10.290, P<0.01). The average score of general self-efficacy was 2.40 ± 0.48, lower than the norm (2.86±0.52), the difference was significant (t=-8.07, P<0.01). Active coping style scores were negatively correlated with job stress (r =-0.294, P < 0.05), negative coping style scores were positively correlated with job stress (r =0.239, P<0.05). General self-efficacy and positive coping scores were positively correlated (r=0.270, P<0.05). Conclusions The job stress among emergency nurses was at high level, self-efficacy was not high, but they still have a positive behavior patterns. Nurse managers should take advantage of the positive psychological characteristics of nurses and give reasonable support and guidance, in order to enhance the confidence of nurses and promote self-efficacy, optimize coping, improve the physical and mental health in emergency nurses.

Aim To investigate the specificity of angiostatin to vascular endothelial cells. Methods S-180 tumor imaging and autoradiography of angiogenesis on Matrigel model was developed with 99 Tcm-recombinant human angiostatin ( 99 Tcm-rhAS) as a tracer, and FCM on human microvascular endothelial cell-1 (HMEC-1) with FITC-rhAS or rhAS antibody. The binding protein of rhAS on HMEC-1 was isolated by af-finity chromatography, and the proteins was sequenced with MS. Results 99 Tcm-rhAS was concentrated on the tumor site in vivo, and the rhAS was specific to angiogenesis of tumor. There were some binding sites on the surface of HMEC-1. Three proteins which are able to bind rhAS were obtained by affinity chromatography, among which tubulin sequenced was an important target for tumor. Conclusion The angiostatin is specific to novel vascular endothelial cell, and its mechanism targeting tumor is complicated.

AIM:To investigate the effects and mechanisms of microRNA-25 (miRNA-25) on the proliferation of human esophageal squamous-cell carcinoma cell line TE1.METHODS: The abundance of miRNA-25 in different tis-sues was measured by RT-PCR.After silencing or over-expression of miRNA-25 with mimics or inhibitor in TE1 cells, the cell proliferation, cell cycle distribution and the expression of cyclin E1 and cyclin-dependent kinase 2 (CDK2) at mRNA and protein levels were measured by CCK-8 assay, BrdU detection, flow cytometry, RT-PCR and Western blot, respective-ly.RESULTS:miRNA-25 was prominent in esophageal mucosal tissue and highly expressed in TE1 cells (P<0.05).O-ver-expression of miRNA-25 increased TE1 cell proliferation, promoted the cell cycle progression and enhanced the en-trance of the cells into S phase (P<0.05).Inverse results were obtained after down-regulation of miRNA-25 (P<0.05). Furthermore, the expression of cyclin E1 and CDK2 at mRNA and protein levels was significantly increased after over-ex-pression of miRNA-25, but decreased after down-regulation of miRNA-25 (P<0.05).CONCLUSION: miRNA-25 en-hances cell cycle transition by increasing the expression of cyclin E1 and CDK2, thus accelerating TE1 cell proliferation. This study provides a novel mechanism by which miRNA-25 increases the proliferation of human esophageal squamous-cell carcinoma cell line TE1, suggesting that down-regulation of miRNA-25 may be a potential new therapeutic strategy for trea-ting esophageal squamous-cell carcinoma.

Objective To observe the effects of adenosine and adenosine receptor agonist on the expression of inter?leukin-18 (IL-18) in patients with unstable angina (UAP), and the mechanism of adenosine receptor agonists thereof. Meth?ods Fifteen UAP and 15 healthy volunteers were included in this study. The effects of adenosine and the selective adenos?ine receptor agonists on the expression of IL-18 were measured by enzyme-linked immunosorbent assay (ELISA). Results The lower concentration of adenosine (1-100μmol/L) increased the expression of IL-18 in UAP group;whereas the higher concentration of adenosine (1 mmol/L) inhibited the expression of IL-18. The adenosine A1 receptor agonist and A3 receptor agonist increased the expression of IL-18, while the adenosine A2a receptor agonist inhibited the expression of IL-18. There was no significant effect for A2b receptor agonist on the expression of IL-18. Conclusion The lower concentrations of ade?nosine can enhance the expression of IL-18 through adenosine A1 and A3 receptors in UAP. The higher concentrations of ade?nosine can inhibit the expression of IL-18 through adenosine A2a receptors. Adenosine can promote IL-18 expression in lower concentrations.
