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 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 study the method, advantage and shortcoming of mini-laparoscopic treatment for indirect inguinal hemia in children. Methods 136 cases with indirect inguinal hernia(right:75cases,left:44 cases,bilateral:17 cases) had been treated by high ligation with mini-laparoscopy. Results The mean operation time was 10 mmin for unilateral hernia and 23 mmin for bilateral hernia. Among 119 cases with unilateral hernia,38 cases had been found with contralateral latent hernia. The mean of postoperative inhospital stay were about 1 ～ 2 day(s). All patients had been followed-up for 3 ～ 12 months,there were only 2 cases recurrence found but no complications was detected.Conclusion Mini-laparoscopic high ligation for indirect inguinal hernia in children is a single, safe, satisfactory, effective,and minimally invasive surgical method.

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 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 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 To explore the protective effects of 10-HDA combined with AA-2G on UVA-induced photodamage in fibroblasts. Methods The primary cultured human skin fibroblasts were divided into three groups: blank control group, UVA irradiation group and 10-HDA+AA-2G group. The cell viability and cellular senescent state were analyzed using CCK-8 and senescence associated-β-galactosidase (SA-β-gal) staining, respectively. Fluorometric assays were performed to detect the formation of reactive oxygen species (ROS) in the cells. Results Compared with those in control group, the cell viability was decreased (P < 0.05), and the SA-β-gal positive cells and ROS level were significantly increased (P<0.01 for both) in UVA-irradiated group. Compared with those in UVA-irradiated group, the cell viability was significantly increased (P < 0.01), and the SA-β-gal positive cells and ROS level were significantly reduced (P < 0.05, P < 0.01, respectively) in the 10-HDA combined with AA-2G group. Conclusion Fibroblasts treated with 10-HDA and AA-2G are significantly protected from UVA-induced cytotoxicity, cellular senescence and ROS, indicating that 10-HDA combined with AA-2G has photoprotective effects. Therefore, 10-HDA combined with AA-2G may be a potential combination for the prevention and treatment of skin photoaging.

Purpose To investigate the diagnostic value of multi-slice spiral CT (MSCT) enhanced scanning in borderline and invasive ovarian tumor,and to provide valuable image evidence for clinical treatment.Materials and Methods One hundred and one patients with pathological-confirmed borderline and invasive ovarian tumor in the First Affiliated Hospital of Jinzhou Medical University from October 2012 to October 2016 were selected,and the preoperative abdominal MSCT enhanced imaging,clinical and pathological data were retrospectively analyzed.The MSCT imaging was observed,and the prediction model of MSCT differentiating borderline and invasive ovarian tumor was established.Results The differences of onset age,menopausal status,tumor solid components,maximum diameter,septa and margin were all statistically significant between borderline and invasive ovarian tumor groups (P＜0.05).The prediction model of MSCT differentiating borderline and invasive ovarian tumor was established using multivariate Logistic regression,on the basis of following variables (OR＞l,P＜0.05):tumor size,solid components and septa.The sensitivity and specificity of the prediction model were respectively 81.3％ (95％ CI:0.622-1.000) and 85.7％ (95％ CI:0.741-0.973) in predicting borderline ovarian tumor for patients before menopause,and respectively 92.1％ (95％ CI:0.835-1.000) and 91.7％ (95％ CI:0.761-1.000) for those after menopause.Conclusion MSCT enhanced scanning is helpful to differential diagnose of borderline and invasive ovarian tumor,and it has important significance for clinical treatment and prognosis evaluation.

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
