In this study, the expression of IL-24 at maternal-fetal interface and the roles in extravillous trophoblast (the TEV-1 cell line) invasion were examined. Immunohistochemistry was used to detect the expression of IL-24 in villi and decidual tissue. The proliferation of TEV-1 cells under the effect of IL-24 was measured by MTT assay. The invasiveness of TEV-1 cells under the effect of recombinant IL-24 (rhIL-24) was examined by transwell system. Immunohistochemical detection showed that IL-24 was expressed in the villi and decidual tissue, and distributed in villous column, trophoblasts, stroma and blood vessels. The proliferation of TEV-1 cells was not inhibited by rhIL-24 of various concentrations. The examination of invasion in vitro showed that rhIL-24 could inhibit the invasion of TEV-1 cells in a concentration-dependent manner. The results suggested IL-24 could inhibit the invasion of TEV-1 cells. Therefore, IL-24 produced by maternal-fetal interface in human first trimester pregnancy may influence the invasion of trophoblasts and is involved in normal pregnancy.

At first this paper discusses the concept,the types,the main expressions,and the explanations of deviant behaviors online. On the basis of above-mentioned discussions,the authors then open up prospects for research and suggest that the concept and the research method,the factors,the influences,the prevention,and intervention strategies of the deviant behaviors online and the relationship between deviant behaviors online and offline are important topics to be explored in the future.

Objective: To explore the relationship among adolescents’ ego identity,internet service preference and pathological internet use. Methods: A survey research method was adopted in which questionnaires were administered to 404 middle school students from Junior I to Senior Ⅱ city. Results: The relationship between ego-identity achievement and pathological internet use was significantly negative(r=-0.19,P

Objective:To explore the developmental characteristics of adolescents' family functioning and its influence on mental health.Methods:928 middle school students in Xi'an were surveyed with The Chinese Family Assessment Instrument and SCL-90.Results:There were grade differences in parental control (F=7.50,P

Objective To evaluate the reliability and validity of Chinese version of Arthritis Self-Efficacy Scale.Methods Arthritis Self-Efficacy Scale was translated and adapted according to Chinese culture,and content validity was evaluated by panel of experts.Then preliminary test was proceeded and revised the scale.90 effective questionnaires were recollected,and 40 patients were tested once again after two weeks randomly.Correlation analysis and factor analysis was conducted.Results The Cronbach's α of Arthritis Self-Efficacy Scale was 0.920 and the Cronbach's α of each subscale was ranged from 0.807 to 0.831.The test-retest reliability was 0.800 to 0.921.The correlations among subscales were ranged from 0.705 to 0.799,the correlations between each subscale and total scale were ranged from 0.875 to 0.921.Component analysis revealed three factors accounting for 56.47％ of the sample variance.Conclusions Chinese version of Arthritis Self-Efficacy Scale is of better reliability and validity,it could be used in the evaluation of self-efficacy for arthritis patients.

The data on nosocomial infection of 4060 patients who were stayed in intensive care unit (ICU) more than 48 h from January 1997 to August 2008 were reviewed.From Jan 2004 the target monitoring of hospital-acquired infection was implemented in ICU.The nosocomial infection rates before and after target monitoring were 35.25% (871/2471) and 30.77% (489/1589) respectively (P ＜ 0.01);however there was no significant difference in case infection rate before and after target monitor were practiced (47.67% vs.45.25%,χ~2 = 2.2836,P ＞0.05).The incidence of Acinetobacter infection was increased after target monitoring.Targeted monitoring can decrease the nosocomial infection rate in ICU,and also reduce the cost of medical care.
