Association of general self-efficacy,self-esteem and professional identification among nursing students / 中华医学教育探索杂志

Objective To analyze the relationship among the general self-efficacy,self-esteem and professional identification of nursing baccalaureate students and to provide some suggestions for educational practice. Methods A total of 403 nursing baccalaureate students in traditional Chinese medicine colleges were recruited. They were investigated with general self-efficacy scale (GSES), Rosenberg self-esteem scale(SES)and questionnaire for baccalaureate nursing students (QBNS). The relationship among general self-efficacy,self-esteem and professional identification was analyzed by multiple stepwise regression analysis. Results The mean score of general self-efficacy was 23.81± 5.27. There were significant differences in the score of general self-efficacy among different grades and enrollment methods (P<0.01). The nursing students,general self-efficacy was positively correlated with self-esteem,professional identification,professional emotion and professional skills(r=0.11-0.50, P<0.05). Conclusions Nursing educator should pay attention to the cultivation of self-esteem and professional identity in the training of nursing student in order to improve the self-efficacy of nursing students.

International Digestive Endoscopy Network 2012: A Patchwork of Networks for the Future

This special September issue of Clinical Endoscopy will discuss various aspects of diagnostic and therapeutic advancement of gastrointestinal (GI) endoscopy, explaining what is new in digestive endoscopy and why international network should be organized. We proposed an integrated model of international conference based on the putative occurrence of Digestive Endoscopy Networks. In International Digestive Endoscopy Network (IDEN) 2012, role of endoscopy in gastroesophageal reflux disease and Barrett's esophagus, endoscopy beyond submucosa, endoscopic treatment for stricture and leakage in upper GI, how to estimate the invasion depth of early GI cancers, colonoscopy in inflammatory bowel disease (IBD), a look into the bowel beyond colon in IBD, management of complications in therapeutic colonoscopy, revival of endoscopic papllirary balloon dilation, evaluation and tissue acquisition for indeterminate biliopancreatic stricture, updates in the evaluation of pancreatic cystic lesions, issues for tailored endoscopic submucosal dissection (ESD), endoluminal stents, management of upper GI bleeding, endoscopic management of frustrating situations, small bowel exploration, colorectal ESD, valuable tips for frustrating situations in colonoscopy, choosing the right stents for endoscopic stenting of biliary strictures, advanced techniques for pancreaticobiliary visualization, endoscopic ultrasound-guided biliopancreatic drainage, and how we can overcome the obstacles were deeply touched. We hope that IDEN 2012, as the very prestigious endoscopy networks, served as an opportunity to gain some clues for further understanding of endoscopic technologies and to enhance up-and-coming knowledge and their clinical implications from selected 25 peer reviewed articles and 112 invited lectures.

Construction and identification of the eukaryotic expression vector carrying specific siRNA of LEDGF p52 gene / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To construct and identify LEDGFp52 eukaryotic expression vector for RNA interference.METHODS: Recombinants were designed and established by targeting gene LEDGFp52 and plasmid pGensil-1 based on LEDGFp52 cDNA sequences of Genomes. Two pairs of oligonucleotides were synthesized according to the Tuschl principle and inserted into plasmid pGenSil-I to generate siRNA eukaryotic expression vector. DH5α strains were transformed, plasmids were extracted, and recombinant vectors were identified by the restriction map and the sequence analysis. The cultured cells were transfected by the recombinant plasmid (pGensil-1-RNA. LEDGFp52-1). At 48 hours after transfection, the whole cell protein was extracted, and the protein level was detected using Western blotting with mouse anti-human LEDGFp52 monoclonal antibody.RESULTS: Recombinant plasmids completely concord with the designs by the restriction map and the sequence analysis,the proteinlevel of LEDGFp52 was down regulated at 48hours after transfecting pGensil-1- LEDGFp52-1 expression vector into HeLa cells, the recombinant eukaryotic expression vectors were successfully constructed.CONCLUSION: siRNA recombinant can be successfully constructed by RNAi technique to inhibit the expression of LEDGFp52.
