Objective To investigate characteristics and psychological mechanisms of creativity of college students by using divergent thinking tasks and creativity potential test.Methods Totally 150 college students were selected and assessed with three types of open-ended divergent thinking tasks (unusual uses task,instances task,consequences task) and the Williams Scale of the Creativity Assessment Packet (CAP) in this study.The divergent productions were scored by two independent raters on fluency,originality,flexibility dimension,and the CAP results were analyzed on risk-taking,curiosity,imagination and complexity.Results (1) The results showed that scores on fluency,flexibility,and originality correlated with each other on each of the three different divergent thinking tasks (P＜0.01).(2) Scores on fluency and flexibility among the three different divergent thinking tasks significantly correlated with each other (fluency:r=0.22,P＜0.01; r=0.47,P＜0.01 ; r=0.26,P＜0.01 ;flexibility:r=0.26,P＜0.01 ; r=0.28,P＜0.01 ; r=0.18,P＜0.05),while the correction coefficients of scores on originality among the three tasks were not significant.(3) Most scores of fluency or flexibility of different tasks were significandy correlated with risk-taking and imagination (P＜0.05),while originality was correlated with different creativity potentials on each task (originality of instances task and imagination:r=0.18,P＜0.05 ; originality of consequences task and risk-taking:r=0.26,P＜0.01 ; originality of unusual uses task and complexity:r=0.17,P＜0.05).Conclusion The results suggest that fluency and flexibility are the general characteristics of divergent thinking,which are associated with imagination and adventure,while originality is specific nature of divergent thinking,which is associated with various creative potentials according to the tasks.

Objective To investigate the rivalry mechanism of ginkgo in rat brain edema after intracerebral hemorrhage.Methods Totally 80 healthy Wistar rats were divided into 4 groups randomly(20 rats in each group).Fifty microliters saline(group A and group B) or auto-hemoglobin(group C and group D) was infused into the right caudate nuclears using stereo tactic guidance.Groups A and C were lavaged 50 g/L carboxymethyl cellulose sodium solution of 3 mL,groups B and D were lavaged the same amount of ginkgo(200 mg/kg) solution dissolved by 50 g/L carboxymethyl cellulose sodium solution once a day for 3 weeks.All the rats were decapitated after raised for 3 weeks,and superoxide dismutase,malondialdehyde,and the number of hemeoxygenase-1(HO-1) positive cells in brains were assayed.Results The differences in SOD and MDA contents as well as HO-1 positive cell number between every two groups were significant(P

Recently the combination of acupuncture with assisted reproductive technology (ART) to increase the outcomes of ART is being widely studied. In this article, the literatures concerning random controlled clinical trials since 2002 are reviewed and the designs of the trials, especially the timing of acupuncture, are evaluated. Over the past 5 years, the related clinical trials have primarily showed that acupuncture done immediately before and after embryo transfer might increase the assisted reproduction rates, but still requiring further high quality trials with large samples; in addition, different stimulation modes could produce different result, and so far there has not been a consensus as to the optimal time-point for the acupuncture intervention during the in vitro fertilization-embryo transfer (IVF-ET) course. Since the effects of acupuncture change with women's endocrine cycles, it is important and possible to make a breakthrough in ART outcomes if acupuncture is performed at a suitable time point during the cycle of IVF/ET combined with ART.

Objective:To study the effect ofmetformin combined with insulin aspart on the serum cholesterol(TC),total Bilirubin (TBil),uric Acid(UA),urinary Micro Protein(mAlb) levels and Maternal and Infant Outcomes of gravida with Gestational Diabetes Mellitus.Methods:84 patients ofgestational diabetes mellitus who received therapy from June 2014 to June 2016 in our hospital were selected.According to random number table,those patients were divided into the observation group (n=42) and the control group (n=42),on the basis of routine treatment,The control group was treated with insulin aspart,while the observation group was combined with metformin hydrochloride.The blood glucose index and the levels of TC,TBil,UA,mAlb and maternal and infant outcomes were compared.Results:After treatment,the levels of fasting blood glucose (FBG),postprandial 2h blood glucose (2hPG),glycosylated hemoglobin (HbA1c),TC,TBil,UA and mAlb in the observation group were significantly lower than the control group,the levels of TBil was significantly higher than the control group (P＜0.05);the incidence ofgestational hypertension,hydramnios,premature birth,cesarean section,giant child and neonatal jaundice were significantly lower than the control group (P ＜0.05).Conclusion:Metformin combined with insulin aspart was well for gestational diabetes mellitus,which could effectively improve the blood glucose indicators and TC,TBil,UA,mAlb levels,maternal and infant outcomes.

Objective To study the expression of WWOX gene in non-small cell lung cancer and its significance. Methods WWOX protein expression was evaluated by immunohistochemistry in 81 NSCLC patients(50 squamous cell carcinomas,31 adenocarcinomas and 20 adjacent normal lung tissues),and correlation with histopathologic(histotype,grade,tumor-node-metastasis,stage) and clinical characteristics was studied. Results WWOX expression was absent/reduced in 72.8% of NSCLC,whereas it was normal in 80.0% of adjacent normal lung tissues.WWOX expression was strongly associated with tumor histology and histologic grade(P

Objective To investigate the training scale and social demand of nursing undergraduates in recent five years in Henan province,and supply reference for trend of talent supply and demand in future five years in Henan province.Methods A cross-sectional questionnaire survey were taken,6 nursing colleges,78 hospitals took part in the survey.Literature searching and trend extrapolation method were used to predict the demand of nursing talents in Henan province from 2011 to 2015.Results Tertiary hospitals demand more nurses with bachelor degree than secondary hospitals; the appropriate proportion of nurses with bachelor degree in all nurses was 30％～50％; besides,a predictive model equation was proposed.Conclusions The scale of undergraduate nursing should develop in appropriate ratio based on the predictive values; we should strengthen undergraduate nursing education for all-around development to adapt tertiary hospitals and community nursing trend,and the predictive model equation needs continuous emendation.

Objectives To investigate the clinical significance of the airway inflammation mediators,eosinophil cationic protein (ECP) and urinary leukotriene E4 (LTE4),in children with respiratory syncytial virus (RSV) bronchiolitis. Methods A total of 120 inpatients with RSV bronchiolitis were classified into atopic and non-atopic groups. And 30 healthy subjects were se-lected as normal controls. Urinary LTE4 was determined by ELISA and ECP concentration in nasopharyngeal secretions (NPS) was tested by UniCAP100 allergen detector. The differences among groups were compared. Results The urinary LTE4 level in atopic group (172.21 ± 67.29 pg/ml) was elevated significantly (P<0.01) than that of non-atopic group (78.21 ± 28.78 pg/ml) and control group (44.22±16.14pg/ml). Significance was also found between non-atopic and control groups (P<0.01). Statistical anal-ysis indicated that urinary LTE4 positively correlated to serum IgE and ECP in children with RSV bronchiolitis (r=0.57,0.49;P<0.01). Conclusions The level of urinary LTE4 and ECP in NPS can provide the reference for treatment and prognosis of children with RSV bronchiolitis.

Objective To study the expression of WWOX, ErbB2 and Ki67 protein in non-small cell lung cancer(NSCLC) and the relationships with cell proliferation. Methods WWOX and ErbB2 protein expressions were evaluated by immunohistochemistry in 81 NSCLC patients (50 squamous cell carcinomas,31 adenocarcinomas and 20 adjacent normal lung tissues) and the correlations with histopathologic cell proliferation were analyzed. Results WWOX expression was absent/reduced in 72.8% of NSCLC, while it was normal in 80.0% of adjacent normal lung tissues. WWOX expression was strongly associated with tumor histology, histologic grade and lymph node metastasis ( X2 = 5.44, P = 0.019 ; X2 = 4.740, P = 0.029, X2 = 4.51, P = 0.034 ), reduced WWOX expression was higher in squamous cell carcinomas and in poorly differentiated tumors. The overexpression of ErbB2 was associated with TNM stage and lymph node metastasis ( X2 = 6.90, P = 0.009 ; X2= 5.68, P=0.017). WWOX expression was negatively related to the overexpression of ErbB2 (r=-0.239, P <0.05 ). WWOX expression intensity was nega-tively related to the high index of cell proliferation (r=-0.252, P<0.05 ). Conclusion The loss of WWOX ex-pression plays different roles in tumorigenesis of NSCLC and is related to high aggressiveness of tumors. The loss of WWOX expression and the overexpression of ErbB2 can estimate the prognosis of NSCLC.

Objective To compare clinical outcome of intracytoplasmic sperm injection(ICSI)cycle by using fresh and cryopreserved-thawed testicular and epididymal spermatozoa in azoospermic patients.Methods Between September 2006 and May 2007,208 azoospermic patients underwent in vitro fertilization(IVF)were treated in Center of Reproductive Medicine,Peking University Third Hospital.Those couples were divided into two groups based on their wishes,including 171 cases in fresh group and 37 cases in cryopreserved-thawed group.The cryopreserved testicular or epididymal spermatozoa were thawed and recovered before ICSI procedure iu thawed group.The outcomes of ICSI in each group were compared.including clinical outcomes(two pronuclear fertilization,high quality embryo,clinical pregnancy and embryo implantation)and pregnancy outcomes(spontaneous miscarriage,gestational weeks and neonatal birth weight).Results (1),The utilization rate were 92%(23/25)in cryopreserved-thawed testicular spermatozoa and 100%(12/12)in epididymal spermatozoa.(2)Between fresh and cryopreserved-thawed groups,no statistical difference was observed in two pronuclear fertilization rate[62.25%(973/1563)vs.64.53%(282/437),P=0.960],high quality embryo rate[78.9%(768/973)vs.79.1%(223/282),P=0.985],clinical pregnancy rate per embryo transfer[44.4%(60/135)vs.46.9%(15/32),P:0.688]and embryo implantation rate[29.3%(84/287)vs.33.3%(23/69),P=0.508].(3)No significant difference between flesh and cryopreserved group was found in spontaneous miscarriage rate (11%vs.7%,P＝1.000),gestational weeks(single birth:39.0 weeks vs.38.7 weeks,P:0.538;twins:36.8 weeks vs.36.3 weeks,P=0.571)and birth weight(single birth:3409 g vs.3350 g,P=0.699;twins:2584 g vs.2635 g,P=0.703).Conclusion It suggested that tissue from the azoospermic patients who underwent diagnostic testieular and epididymal biopsy should be eryopreseved for IVF-ET.
