Objective:To determine the prevalence and compare the related factors of depressive symptoms among urban primary school students in Hefei and Shenzhen.Methods:Participants from Hefei and Shenzhen were asked to fill out the questionnaires including Children's Depression Inventory(CDI)and items of Social Support and demography.Results:The prevalence of depressive symptoms was significantly higher among the participants in Hefei(11.9%)than that in Shenzhen(8.2%)(?2 =10.37,P=0.001).The students with depressive symptoms had significant lower social support scores than those with no depressive symptoms in Hefei and Shenzheng cities(Parents support score was 3.6?1.6 vs 5.0?0.9,school support score was 2.1?0.9 vs 2.6?0.8,peer support score was 3.2?1.5 vs 4.4?1.0,total support score was 8.9?2.9 vs 12.0?1.8 in Hefei.Parents support score was 3.4?1.8 vs 4.9?0.7,school support score was 2.2?1.2 vs 2.9?0.8,peer support score was 3.4?1.5 vs 4.4?0.9,total support score was 9.0?2.7/12.3?1.6 in Shenzheng,all P

Objective:To investigate whether lanthanum(La 3+)can enter into ossification induced bone marrow stromal cells(BMSCs)cultured in vitro and its influences on the ultrastructure of BMSCs.Methods:Dog BMSCs were ossification induced and the cells of the third passage were cultuerd with the presence of lanthanum chloride(LaCl_3)at 5.564?102,5.564 and 5.564?10-2 ?g/ml respectively for 5 days,the same passage cells without LaCl_3 treatment were used as the controls.Transmission electron microscope(TEM),electron microprobe with wave spectrum(EMWS)and high resolution TEM with energy spectrum(HRTEM)were used to observe the change of BMSCs ultrastructure and the distribution of lanthanum ions in the cells.Results:Electron-dense granules in lysosome were observed in BMSCs treated with LaCl_3 but not in control BMSCs under TEM.Slight denaturation of some organelles was found in both LaCl_3 treated and control cells.EMWS examination showed that there was La element in BMSCs treated with 5.564?102 ?g/ml LaCl_3.La element was not found in all the treated cells under HRTEM.Conclusion:La 3+ at a certain concentration might enter into the ossification induced BMSCs cultured in vitro.

Objective To investigate the HBV- positive pregnant women about the knowledge of the route of hepatitis B transmission, hepatitis B hazards, health care during pregnancy, announcements of child- care to explore targeted and effective health education model with self- designed question-naires. Methods Nurses in obstetrics department carried out this questionnaire investigation in the outpa-tients of HBV- positive pregnant women, after that the results underwent statistic analysis. Results The overall knowledge of HBV- positive pregnant women in announcements of child- care, health care during pregnancy and hepatitis B hazards was not very well, and the announcements of child- care was the lowest, followed by health care during pregnancy and hepatitis B hazards. The route of hepatitis B transmission was better, but still not satisfactory. The education should highlight these areas. Well- educated women were better than those who lack education. The age between 20 to 30 years old was better. Conclusions The HBV-positive pregnant women is lack of heath knowledge, so we should gave health intervention in a multi- level, multi- stage standardized and a variety of ways.

Objective To evaluate the strictness and self-consistency of the charge nurses in the nurses examination using venipunctnre trocar operation as research object.Methods FACETS,the polyhedral Rasch software was used in the examination.Results The strictness and self-consistency of charge nurses were evidently different.Conclusions The variable strictness and self-consistency of the charge nurses in the examination leads to unreliability of the results.Developing a scientific and reliable evaluation system is essential to improve the ability of the teaching nurses and the student nurses as well as the hospital nursing quality.

Objective To understand the job burnout status of bank staff and analyse the relationship between job burnout and self-efficacy,job satisfaction.Methods The job burnout,self-efficacy and job satisfaction of 8 942 bank staff was surveyed by Maslach burnout inventory-general survey(MBI-GS),general self-efficacy scale (GSES) and job satisfaction scale (JSS) respectively.Results A total of 8 942 questionnaires were issued and 7 486 valid questionnaires were returned.The score of self-efficacy in male was significantly higher than that in the female(P ＜0.05).There was no significant difference in job satisfaction score between male and female(P ＞ 0.05).The score of emotional exhaustion (EE) in female was significantly higher than that in male,while the score of reduced personal accomplishment(RPA) was significantly lower than that in male (P ＜ 0.05);there was no significant difference in depersonalization (DP) score between male and female (P ＞ 0.05).The EE,DP and PAL scores of bank staff with post-graduate education were significantly lower than those with high school/secondary school and junior college/undergraduate (P ＜ 0.05);the DP and PAL scores of bank staff with junior college/undergraduate were significantly lower than those with high school/secondary school(P ＜ 0.05);there was no significant difference in EE score of bank staff between junior college/undergraduate and high school/secondary school(P ＞ 0.05).The EE score of age ＞ 50 years old bank staff was significantly lower than that of age ＜ 30 years old,30-40 years old and 41-50 years old (P ＜0.05);there was no significant difference in EE score among age ＜30 years old,30-40 years old and 41-50 years old bank staff (P ＞ 0.05).The DP score of 41-50 years old bank staff was significantly higher than that of age ＜ 30 years old (P ＜0.05);there was no significant difference in DP score among age ＜30 years old,30-40 years old and 41-50 years old bank staff (P ＞ 0.05).There was no significant difference in PAL score among all age groups (P ＞ 0.05).The three dimensions of job burnout had significant negative correlation with self-efficacy and job satisfaction (P ＜ 0.05).Conclusion Bank staff have a certain degree of job burnout.Age,sex,and education level maybe the influence factors of job burnout.Improvement of self-efficacy and job satisfaction may help to reduce the job burnout.
