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.

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.

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: 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.

Objective To investigate the therapeutic potential of brain-derived neurotrophic factor (BDNF) and Schwann cells(SCs) in experimental autoimmune neuritis (EAN) and assess the effect and mechanism.Methods EAN model was established by immunization of Lewis rats with 400 μg of specific peptide P2(57-81)and complete Freund adjuvant.In the therapy group,the SCs (n =28) and the combination of BDNF administration and SCs (n =48) were labeled by the nuclear fluorescent dye injected into the intracerebroventricularly in 14 d after immunization.Transplanted cell migration tracking respectively were at 25,35 and 45 days after immunization.The rats were observed for signs of disease daily and subjected to clinical score,of which the sciatic nerves were subjected to histopathological examination (hematoxylin eosinstaining,luxol-fast-green and immunohistochemical staining).The inflammatory cell infiltration and demyelination were assessed,and the CD4,CD8,CD68,S-100 and nerve growth factor (NGF) positive cells numbers were compared among the 3 different groups.Results AIl the rats had the neurological deficits.Compared with control group,there were no significant differences in SCs therapy group.In SCs + BDNF therapy group,the recovery of paralytic symptom was faster and the score was lower after immunization 45 d.After immunization 25 and 35 days,both the inflammatory cells infiltration (EAN model group:325.8 ±10.8,221.4 ± 35.2;SCs + BDNF transplantation group:307.3 ±4.6,197.2 ± 16.8; t =2.172,P =0.031 ;t=3.756,P=0.000) and the expression of CD4+,CD8+ T cells and CD68+ macrophages were reduced.After immunization 35,45 days,the demyelination degree (EAN model group:3.4 ± 0.5,2.9 ± 0.8 ; SCs +BDNF transplantation group:2.9 ±0.8,2.3 ±0.5) was reduced (t =-7.408,P =0.000;t =-6.092,P =0.000),the expression of S-100 is higher,and NGF was lower than the control group in each time point after immunization.Conclusions SCs transplanted into the cerebellar ventricle of animals can migrate into the sciatic nerve.The combination of BDNF administration and SCs transplantation may represent an effective strategy by reducing inflammation reaction,improving the expression of S-100 in the donor cell,and reducing NGF irritability heighten in sciatic nerve.However,delivery of SCs alone is inefficiency to the treatment of EAN.

Clinician-scientists are doctors who perform laboratory-based or clinically oriented research and have direct patient contact.Not only do they play a critical role in the research and practice of translational medicine,but also they are the educators of the next generation of clinician-scientists.However,clinician-scientists are vanishing.It is urgent to train new clinician-scientists who can be engaged in clinic work,research,and also education.Thus,in order to correct understand the importance of the work of clinical scientists,from multi angle analysis of clinical scientists training problems that may be encountered in the process,the active improvement of the education system and condition,and sustained and efficient guidance to the outstanding seedlings are advocated.Besides,aspiring candidates are also encouraged to seek ideal guidance and support through their career,arrange their work reasonably,strengthen their cooperation and the management ability,and strive to grow into excellent clinician-scientists.

Objective To investigate the clinical effect of high dose of calcitriol on end-stage renal disease (ESRD) in patients with secondary hyperparathyroidism (SHPT). Methods The clinical data of patients with ESRDcomplicated with SHPT were retrospectively analyzed. According to the treatment method were divided into control group and observation group, the control group were given conventional dose of calcitriol treatment, the observation group were treated with high dose of calcitriol. The differences of calcium and phosphorus levels, parathyroid hormone (PTH) level and quality of life were observed between the two groups before and after treatment. Results The serum phosphorus, calcium and calcium-phosphorus product in two groups of patients before treatment had no significant difference. After treatment, the above indicators decreased in two groups of patients compared with those before treatment, and the observation group was significantly lower (P<0.05). Before treatment, there was no difference in the levels of PTH between the two groups. After treatment, the level of PTH in the observation group was lower than that in the control group, and the difference was statistically significant (P<0.05). There was no significant difference in quality of life between the two groups before treatment. After treatment, the quality of life in the two groups were higher than before treatment, and the observation group was significantly higher (P<0.05). Conclusion High dose of calcitriol has good therapeutic effect for ESRD patients with SHPT and can significantly improve the patient's calcium and phosphorus and PTH levels, improve the quality of life of patients.

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.
