Objective:To investigate the relationship between narcissism and entrepreneurial intention and roles of achievement motive and risk aversion in college students.Methods:In this study,375 college students were selected from Henan University.Their narcissism,entrepreneurial intention,achievement motive and risk aversion were assessed with the Narcissism Scale,Entrepreneurial Intentions,The Achievement Motive Scale,and General Risk Aversion Scale.Results:The scores of overt narcissism positively predicted the scores of entrepreneurial intention (3 =0.37,P ＜ 0.001),the predictive effect of covert narcissism on entrepreneurial intention was not significant (β =-0.05,P ＞ 0.05).The scores of achievement motive partly mediated the relationship between the scores of overt narcissism and entrepreneurial intention (95％ CI:0.06-0.22),and this mediation effect was moderated by the scores of risk aversion (β =0.09,P ＜ 0.05).Only when the score of risk aversion was higher (above one standard deviation),achievement motive was a mediator between narcissism and entrepreneurial intention.When the score of risk aversion was lower,the mediate effect was not valid.Therefore,the moderated mediation model was confirmed.Conclusion:It suggest that the moderated mediation model is feasible,that is,achievement motive is a mediator between narcissism and entrepreneurial intention,but this mediation is moderated by risk aversion.

High incidence of liver metastases from colorectal cancer was found. To the patients with liver metastases from colorectal cancer, regardless of whether the liver metastases could be resected or not, hepatectomy after neoadjuvant chemotherapy was recommended. The combination of cetuximab and chemotherapy based on irinotecan and oxaliplatin as the second-line and first-line for the liver metastases from colorectal cancer could get higher response and longer survival, and more patients got the chance of hepatectomy. However, cetuximab was only good for the colorectal cancer patients with wild-type k-ras.

Objective Diagnosis of GDM during the early period and treatment in time can improve motherchild prognosis.Methods 805 pregnant women with gestational age of 24～28 weeks were screened by the 50g 1hour glucose challenge test(GET).75g oral glrcose tolerance test(OGTT)were further performed in the abnormal pregnant women,and the normal or abnormal pregnant outcomes were followed.Results The morbidity of pregnant women and neonates were higher in-group of gestational impaired glucose tolerence(GIGT)and geztational diabetes mellittts(GDM)(P＜0.05 or P＜0.01).Conclusion The research suggests that all pregnant women must be screened for detecting diabetes mettitus.The abnormality of glucose tolerance test need to be further treated and monitored.

Objective: A cross-sectional study was conducted to determine the general symptom clusters and study its influence on life quality of cancer patients in community. The association between the symptom clusters and life qualities was analyzed to provide guidance for targeted intervention. Methods: We randomly selected 200 cancer patients living in Pengpu Community from "Shanghai Cancer Patients Database". They filled in the Chinese version of Functional Assessment of Cancer Therapy-General (FACT-G) selfrating scale. Partial correlation and multiple linear regression analysis were used for statistical analysis. Results: Partial correlation analysis showed that symptom clusters had no apparent correlation with the score of social/family well-being in FACT-G scale. The symptom clusters including anorexia, insomnia, fatigue, pain, and diarrhea mainly correlated with the scores of FACT-G self-rating scale. Multiple linear regression analysis explained 13.2% of the variance in FACT-G score, explained 41.8% of the variance in physical well-being, explained 27.0% of the variance in emotional well-being, and explained 4.2% of the variance in functional well-being, respectively. Conclusion: The life qualities of tumor patients in Shanghai community were associated with anorexia, pain, and insomnia named as QOL-related symptom clusters. Paying attentiation to QOL-related symptom clusters may help health care professionals to increase the intervention efficacy and improve the life quality of tumor patients.

BACKGROUND:Nuclear transcription factor(NTF) ?B is a transcription factor,which exists universally in eukaryocyte.It has been identified that its overacting is correlated to the ongoing and development of many diseases.Among the pathomechanism of rheumatoid arthritis,the abnormal activation of NTF ?B has a lot to do with the inflammatory hyperplasia of synovium and the erosion of tissue around articulation.OBJECTIVE:To review the recent progress of NTF ?B,pathogenesis and treatment of rheumatoid arthritis.RETRIEVAL STRATEGY:A computer-based online search of PubMed database was undertaken to identify the articles published in English from January 2000 to July 2007,with the Key words of "nuclear transcription factor ?B,rheumatoid arthritis,pathogenesis,treatment".Meanwhile,Wanfang database was searched for the related Chinese articles published between January 2000 and July 2007,with the same key words in Chinese.A total of 72 articles were finally selected for the first trial.Inclusive criteria:the articles focus on the NTF ?B,the pathogenesis and treatment of rheumatoid arthritis.Exclusive criteria:repeated experiments.LITERATURE EVALUATION:Among the 30 inclusive literatures,7 were related to reviews while the others were clinical or basic researches.DATA SYNTHESIS:①NTF ?B is a significant transcription factor,which participates in regulating many genes related to immune function and inflammation reaction.The promoters of many genes have the binding sites of NTF ?B.②It is indicated that the abnormal activation of NTF ?B plays an important role in the pathogenesis of rheumatoid arthritis.In recent years,many researches inhibiting its activation through different components of signaling pathways have been doing,which become very hot in anti-inflammatory and anti-rheumatism treatment.③In recent years,people have been making great progress in the therapy of rheumatoid arthritis aiming at cytokine and its receptor,however,interfering NTF ?B to treat rheumatoid arthritis is still in study stage.CONCLUSION:NTF ?B target therapy provides a new therapeutic strategy for the treatment of rheumatoid arthritis,which is a very exciting prospect indeed.

Methods 180 women with postmenopausal osteoporosis were randomized to receive combination therapy and independent therapy with compound danshen tablets and alendronate for 6 months. Scores of VRS were assessed,mean serum alkaline phosphatase, serum osteocalcin, urinary creatinine, urinary hydroxyproline, urinary calcium were detected. Bone mineral density of lumbar vertebra 1 ~5 was determined by dual X - ray absorptiometry. Results Mean serum alkaline phosphatase, serum osteocalcin, and urinary creatinine, urinary hydroxyproline, urinary calcium were statistically different between the combination therapy group and the independent therapy group, and bone mineral densities increased in all therapy groups while there was higher elevated level in the combination therapy group. Conclusions The combination therapy of compound danshen tablets with alendronate has a favorable influence on women with postmenopausal osteoporosis.

Background and purpose:Fumagillin is an inhibitor of type 2 methionine aminopeptidase that can block blood vessel formation. However, its molecular mechanism and therapeutic value in colon cancer still remain to be elucidated.In this study, the effect of Fumagillin on the growth of colon cancer was examined. Methods:Twenty mice were divided into 4 groups and injected subcutaneously with 5?105/L WiDr or HT-29 cells in 200 ?L phosphate-buffered saline (PBS) respectively. After 4 weeks, intraperitoneal injections of Fumagillin (0.1 mg/kg), Cyclo (1 mg/kg), or both were given every 2 days for 4 weeks. The tumor weight and microvessel density (MVD) were examined. Geneexpression profiles were examined by microarray analysis of human umbilical endothelial cells (HUVECs). Results: The Fumagillin-treated mice showed smaller tumor mass and lower MVD-CD105 levels than control ones. In vitro proliferation and tube formation of HUVEC was also significantly decreased by Fumagillin. Microarray analysis of Fumagillin-treated HUVECs showed up-regulation of 71 genes and down-regulation of 143 genes. Expression changes were involved in cell proliferation, migration, adhesion and gene transcription. Quantitative real time-polymerase chain reaction and Western blot revealed decreased expression of cyclin E2, activated leukocyte cell adhesion molecule (ALCAM), and intercellular adhesion molecule-1 (ICAM-1) genes in the presence of Fumagillin. Conclusion: Fumagillin was found to suppress colorectal cancer growth by suppressing angiogenesis. The down-regulation of cyclin E2, ALCAM and ICAM-1 by fumagillin may be involved in the anti-angiogenesis.
