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 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 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.

To investigate the advantage of using the medical sodium hyaluronate gel undergo goniosynechialysis, and to compare the difference of the viscoelastic agent and perfusion fluid by clinical control study.
●METHODS:Totally 103 cases (103 eyes) patients who had angle- closure glaucoma (ACG) with cataract all in Beijing Tongren Hospital affiliated to Capital Medical University, from September 2012 to February 2013. All the patients had primary glaucoma or recurrence ACG with cataract. Their intraocular pressure (lOP) could be controlled in normal value using one or two anti -glaucoma medications. We divided all the patients into two groups by chance. Experimental group had 53 cases (50 eyes), and control group had 50 cases (53 eyes). Two groups all had been performed phacoemulsification combined with goniosynechialysis by the same experiential operator. But experimental group did goniosynechialysis using the medical sodium hyaluronate gel, control group did goniosynechialysis using perfusion fluid. We observed the change of lOP, central anterior chamber depth and anterior chamber structure of two groups in postoperative 1mo.
●RESULTS: SPSS19. 0 statistics software was utilized to analyze the data, This study selected one- side test α =0. 05, adopted paired t - test or two- sample t - test. We obtained that experimental group lOP decreased 12. 42 ± 0. 04mmHg, anterior chamber depth increased 1. 276 ± 0. 201mm; that control group lOP decreased 6. 56 ± 0. 08mmHg, anterior chamber depth increased 0. 852 ± 0. 132mm. And experimental group anterior chamber angle opened more widely than the other group, the comparison had statistical significance (P<0. 05).
●CONCLUSlON: ln phacoemulsification combine with goniosynechialysis,use medical sodium hyaluronate gel do goniosynechialysis can more effectively decrease lOP. This because the medical sodium hyaluronate gel has high glutinousness, it can separate angle of anterior chamber and controlling lOP effectively.
