Objective To investigate behavioral disposition of nurses in emergency room and analyze influential factors.Methods A total of 200 nurses from the emergency room participated in the survey using demographic questionnaire and the nursing behavior questionnaire.Results The total average score of the nursing behavior was(3.13±0.54),and the influential factors included the level of hospital,the time span for the job and the continued education on the infectious diseases(all P<0.01).Conclusions The nursing behaviors was at the medium level.The nursing administrators should provide the nurses with personal protection apparatus,strengthen education on infectious diseases and use incentive mechanism so as to improve the ER nurses' nursing behavior.

Objective This study investigates the effect of collectivism-individualism on parenting goals of middle school students' parents. Methods COLINDEX and Kohn's Parental Values Survey were used. 378 parents participated in the study. Results Fathers had higher score(3.23±0.73) on individualism than do mothers (3.05±0.44,F(1,359)=5.25,P <0.05);and highly educated (college or above) parents had higher scores(4.00±0.86) than do those with less education(for senior high school:3.91±0.81; junior high school or below:3.83±0.97,F(2,363)=4.72,P <0.01). Regression analysis indicated that collectivism had significant effects on goals of "take responsibilities and adapt to environment" ( P <0.01) and "conform to norm and obey parent" ( P <0.01). Both collectivism and individualism had significant effects on goal of "explore and be enterprising" ( P <0.05;P <0.01). Conclusion Parents with high collectivistic value expected their children to assume responsibilities,to adapt to the society,to adhere to norms and to obey authority. However,parents with high individualistic value encouraged their children to be independent and enterprising.

Objective To reduce the complications of male indwelling urinary catheter and improve patient compliance by improved the traditional male urinary catheter.Methods Inspired by using ‘condom’‘fresh-keeping bags’and other pseudo catheter in clinic,the tradi-tional male urinary catheter was improved as‘pseudo catheter ’and the hydrocolloid dressing was used as bonding device.Results An im-proved male urinary catheter was successfully designed,which applied in 68 patients without urinary tract infection,catheterization failure nor foreskin edema.Conclusion The improved male urinary catheter has the advantages of less cost,simple operation,no pain,higher patient com-pliance and less complications,wihch is worthy to spread in clinic,especially in young patients and long-term bedridden elderly patients at home.

Objective To observe the effect of early mild hypothermia on the opening of tight junction of cerebral endothelial cells following traumatic brain injury in order to illustrate possible mechanism of low permeability of blood brain barrier (BBB) treated by mild hypothermia. Methods A total of 90 Wistar rats were randomly divided into normothermia control group (n=10),normothermia injury group (n=40) and mild hypothermia group (n=40). The opening state and its extent of tight junction were observed using lanthanum trace labeling with electron microscope. At the same time,water content of cerebral tissue at different phases in normothermia injury group and mild hypothermia group was measured by means of dry-wet weight and analyzed statistically. Results The tight junction was under preliminary opening three hours after trauma and reached the maximum opening within 24-48 hours after trauma,lasting for 72 hours in the normothermia injury group. However,slight opening appeared only in the mild hypothermia group. Water content of cerebral tissue in the mild hypothermia group lessened obviously in contrast to that in the normothermia injury group,with significant difference 3,24 and 72 hours after trauma ( P

In the future,anti-ship missiles(ASM) will be major weapons in the sea war.It is very important to handle the profile of the casualties aboard warships attacked by ASM for development of naval health service.The statistical result shows there is a greater chance of casualties but less chance of warships being sunken by ASM.Besides,medical staffs should pay more attention to the first aid for victims due to blast,burn,smoke inhalation and penetration while the danger of the sea water immersion should not be ignored.

Objective To explore the role of apoptosis and Fas, bax and bcl-2 proteins in the pathogenesis of testicular carcinoma. Methods Cell apoptosis was determined with TUNEL and flow cytometry, and the expression of Fas, bax and bcl-2 proteins were detected by cellular immunofluoresence technique in 56 cases of testicular carcinomas. Results Apoptotic index was closely correlated with the pathological type and lymph node metastasis of testicular carcinomas(P0.05). The apoptotic index was positively correlated with Fas and bax expression, and negatively correlated with bcl-2 expression (P

Objective To explore the construct validity of collectivism and individualism scale( COLINDEX) and the reliability and construct validity of its Chinese revision;and to study the development of middle school students' value. Methods The revised scale was used and 5875 middle school students were tested. Resuits Two-factor model of COLENDEX was not substantiated by data,while three factors were abstracted by EFA and confirmed subsequently by CFA. Four factors were abstracted from the Chinese revision of COLINDEX, and four-factor model was confirmed. The Cronbach's alpha coefficients of the total scale (0.90) and four sub-scales (0.84,0.76,0.84 and 0.74 )were all significantly high. MANOVA was performed to detect gender and grade differences of means in the four dimensions of the revised scale. The main effects of gender and grade reached the significant level; however, interaction between them did not. Conclusion Collectivism and individualism, two dimensions of Chinese middle school students' value, were not mutually independent. The revised version of COLINDEX was qualified to be used in further research. The grades on collectivistic items of middle school students were higher than those on individualistic items.

Objective To investigate the effect of baicalin on inflammatory factors and oxygen free radical metabolism in patients with traumatic shock.Methods 38 patients with traumatic shock were treated with baicalin 200mg intravenous injection when admitted to hospital.Before and 1 h after treatment,TNF-α,IL-6,IL-8,MDA and SOD were measured in blood.Results Compared with before treatment,TNF-,IL-6,IL-8,and MDA levels were decreased after treatment (t =7.32,6.12,20.21,16.10,all P ＜ 0.05),while SOD activity was significantly increased (t =1.69,P ＜ 0.01).Conclusion Baicalin could inhibit the production and release of inflammatory factors TNF-α,IL-6,IL-8 in patients with traumatic shock,reduce the damage of oxygen free radicals to the cells.Early treatment with baicalin had protective effect on patients with traumatic shock.

Objective To explore diagnosisand treatment of intestinal obstruction by foodballs in children. Methods The clinical datum of 21 cases of intestinal obstruction by foodballs in children were retrospectively ana- lyzed.Results While admission,only 2 cases could provide the history of having eaten foodballs wholly which could not be digested easily.The characteristics of clinical manifestation were intestinal obstruction completely or incom- pletely.All 21 cases had been treated conservatively first,only one case was successful and the other 20 cases had been cured by surgery afterwords.Conclusion There is no specific feature in clinical manifestations of intestinal ob- struction by foodballs in children,so it is difficult to make the diagnosis,but it must be considered suspicious especial- ly for those from rural area and with simple intestinal obstruction with reasons not known yet.If conservative therapy is failure in a short period,an operation should be done immediately.During operation,it is necessary to examine the whole digestive system thoroughly.
