Objective:To explore the relations of psychological stress reactions to workplace violence and so-cial acknowledgement among emergency nurses.Methods:Totally 444 emergency nurses from 8 tertiary hospitals and 1 second A hospital in Beijing were selected.Psychological stressful reactions were measured with the Impact of Event Scale-Revised (IES-R).The social acknowledgment from general society and family to victims was assessed with the Social Acknowledgment Questionnaire (SAQ).Results:Among the 444 samples,96.8% sustained verbal assaults,43.2% underwent physical assaults,32.0% encountered threats,and 4.3% suffered sexual assaults.The results of ANOVA analysis indicated that nurses who suffered 3 types of violence had higher scores of IES-R than the ones who endured one type of violence and 2 types of violence[(22.0 ±16.1)vs.(15.4 ±15.6),(18.1 ± 16.1),Ps <0.01)].Similarly,those nurses who suffered 4 types of violence had higher scores of IES-R than the ones who enduredone type of violence and 2 types of violence [(33.4 ±17.1)vs.(15.4 ±15.6),(18.1 ±16.1), Ps <0.01].Regressive analysis showed that family disapproval,general disapproval,and violence types predicted psychological stress reactions,(β=0.13 -0.40,P <0.05,adjust R2 =0.27).Conclusion:It suggests that violence types,social disapproval and family disapproval may play vital roles in predicting the degree of posttraumatic dis-tress in emergency nurses after suffering from hospital violence.

Objective To explore the expression and significance of Annexin Ⅱ protein in ovarian adenocar-einoma.Methods The expressions of Annexin Ⅱ protein were detected in 48 cases of ovarian adenocarcinoma and 10 cases of ovarian adenoma by SP immunohistochemistry.Results The positive rates of expression of Annexin Ⅱprotein in ovarian adenoma were 50.00% (5/10), and were 81.25% (39/48) in ovarian adenocareinoma (χ2 =4.414, P <0.05), in well and moderately-differentiated, poorly differentiated ovarian serous adenocarcinoma were 93.33% (14/15) and 78.95% (15/19) respectively (χ2 = 1.383 ,P0.05 ), and on the Ⅰ and Ⅱ stage, Ⅲ and Ⅳ stage of ovarian serous adenocarcinoma were 60.00% (6/10) and 95.83% ( 23/24 ) respectively (χ2=7.226, P <0.05).The positive rate in the group of ovarian serous adenocarcinoma with lymph node metastasis was 90.00% (27/30), while 50.00% (2/4) in the group without lymph node metastasis (χ2=4.502, P<0.05).Conclusion The positive expression of Annexin Ⅱ protein may be correlated with the carcinogenesis, development and lymph node metastasis of ovarian serous adenocarcinoma.

Objective To summarize the clinical experiences of total cavopulmonary connection (TCPC), investigate the applications and short and mid term effects. Methods From 1999 to 2007,31 patients with complex congenital heart disease underwent TCPC. All patients were divided into child group(≤16 years old ,n =21 ) and a-dult group( n = 10 ), including 15 cases of functional univentricle, 8 cases of complete atrioventricular septal defect with double outlet of right ventricle, 3 cases of transposition with double outlet right ventricle, 3 cases of tricuspid atresia, 1 case of double outlet of right ventricle with hypoplastic left heart. 1 case of corrected transposition of the great arteries with TOF. Among them, 1 patient had cortriatriatum, 10 patients had left superior vena cave, moderate or severe mitral valve insufficiency occurred in 1, moderate atrioventricular valve insufficiency occurred in 3.28 pa-tients underwent TCPC with cardiopulmonary bypass ( CPB ) and 3 patients without CPB ;Of them, 21 patients were treated with extracardiac conduit and 10 cases with intratrial lateral tunnel. Results There was no early death,post-operative death or large quantities of pleural effusion in child group;but two deaths and three patients with large quantities of pleural effusion in adult group. One case caught up in inferior venous stasis and was cured. Follow- up was carded out from 6 months to 6 years. 26 patients were in NYHA class Ⅰ ,2 patients in NYHA class Ⅱ and only one patient in NYHA class Ⅲ. Conclusions TCPC is effectively used for complex congenital heart disease which can not be corrected in anatomy;serious postoperative complications often occur in adults. Atrioventricular valve in-sufficiency decisively affects the short and midterm effects, even the long-term effects.

Objective To reveal the incidence and types of acid-base disorder (ABD) of critically ill patients in emergency.Methods The clinical data of critically ill patients in the resuscitation room were collected prospectively from December 1,2008 to March 31,2009.Both arterial and venous blood samples were collected to detect arterial blood gas analysis and serum electrolytes simultaneously and their ABD were analyzed.Results Of totally 766 cases,the incidence of ABD was 97.3％ (745 cases).Among ABD the simple acid-base disorder ( SA BD) was 149 cases ( 20.0％ ),dual acid-base disorder (DABD) 525 (70.5％ ) and triple acid-base disorder (TABD) 71 (9.5％ ).After calculating anion gap (AG),the incidence of TABD increased from 12 to 71 cases and the missed diagnosis rate were 83.1％ (59 cases) and after calculating potential HCO3-,the incidence of TABD increased from 8 to 71 cases and the missed diagnosis rate were 88.7％ (63 cases).The age of patients with TABD (77.9 ± 10.7 years old) was older ( P ＜ 0.01 ) than that of other two groups of SABD and DABD as well as APACHEⅡ score (25.9 ± 7.1 ) and incidence (22.5％ ) of MODS in TABD were higher (P ＜0.01 ).The mortality of patients with TABD on the first,second,third and seven day were 14.1％,23.9％,26.8％ and 38.0％ respectively and significantly higher than those in SABD and DABD (P ＜0.05 or P ＜0.01 ).Conclusions The incidence of ABD was 97.3％.Calculation of AG and potential HCO3- would help find metabolic acidosis and TABD.The age and APACHEⅡ score were key factors to poor prognosis of patients with TABD.

Objective To investigate the interaction between uropathogenic Escherichia coli (UPEC) and host uroepithelial cells, define the role uroepithelial cells play in initiating and modulating the host response to infection with UPEC strain. Methods The human bladder transitional epithelial EJ cells were evaluated for their capacities to allow the adherence and invasion by UPEC132, a clinical strain isolated from Tianjin, China, and a cDNA microarray for 22 000 human genes was used to identify the gene expression differences between EJ cells infected with UPEC132 and uninfected EJ cells. Results Microscope observation showed that UPEC132 could adhere to EJ cells with the adherence rate of (73.20 ± 5.26)%. And visualization by confocal microscope revealed that this microorganism could be seen within the cells. EJ cells infected with UPEC132 changed mRNA expression of a total of 29 genes, including 28 genes up-regulated and 1 gene down-regulated. Of these, regulators of growth and proliferation, cytokines, and modulators of apoptotic responses were the most prominent. Conclusion The gene expression profiling of EJ cells is affected by the infection of UPEC strain. The differentially expressed genes may contribute to further investigate the interaction of UPEC and uroepithelial cells.

Objective:To investigate the causes, characteristics and treatment of maxillofacial trauma in children. Methods: A retrospective analysis of 470 consecutive maxillofacial records of the patients not older than 14 years was conducted. Data regarding age, gender, cause, anatomic site and treatment were reviewed. Results:Most of the patients were mals(335 cases, 71.3% ), with a male and female ratio of approximately 2. 5;1 of the injuries, 28. 5% were due to accidental falls, 17.0% traffic accidents and 10.0% sharp implementt cutting. Injuries of soft tissue often occurred on gingiva, cheek, lip and chin. Mandibuir fratures were the most common (55.1% ) of all bone fractures. Conservative therapy, such as closed reduction surgery, maxillomandibular fixation, was usually performed. Conclusion: ①Boys are more tendent to be victims of maxillofacial trauma than girls. ②Falls are the first cause of child victims. ③Gingiva, chin, lip, check and mandible are the most commonly injuried sites.
