Objective To study the teaching effects of using case discussion-analysis method in the teaching course of Nursing Research among nursing students and then put forward suggestions for improving teaching.Methods By way of case discussion-analysis,a part of teaching contents of Nursing Research were taught to the 118 nursing students in 2003 grade.The teaching effect was evaluated by observing the design ability of scientific research,the learning interest,learning attitude,etc.Results The design ability of scientific research,recognition of Nursing Research,learning attitude and learning interest,etc of the students were significantly improved.Conclusions Case discussion-analysis method could effectively excite the interest and the potential of students and then improve the ability of discovering and solving problems.

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.

Background: High-dose dual therapy (HDDT) is a novel regimen for the eradication of Helicobacter pylori (Hp) infection, however, its efficacy and safety remain unclear. Aims: To evaluate the efficacy, safety and compliance of HDDT for Hp eradication. Methods: Randomized controlled trials (RCTs) on HDDT for eradication of Hp infection were retrieved from PubMed, Embase, The Cochrane Library, Web of Science from the date of database establishment to October 2020. Literatures were enrolled according to the inclusion and exclusion criteria, and the data were extracted. RevMan 5.2 software was used for performing meta-analysis. Results: Nine RCTs including 2 627 patients were included. Meta-analysis results showed that no significant differences in ITT eradication (85.4% vs. 79.8%, RR=1.03, 95% CI: 0.96-1.10, P=0.40), PP eradication (88.7% vs. 83.4%, RR=1.01, 95% CI: 0.95-1.08, P=0.68), and compliance (96.5% vs. 95.9%, RR=1.01, 95% CI: 0.99-1.02, P=0.37) were found between HDDT and the guideline-recommended regimens, however, the incidence of adverse events was significantly decreased in HDDT (15.3% vs. 27.0%, RR=0.57, 95% CI: 0.42-0.76, P=0.000 2). Conclusions: There are no significant differences in eradication rates and compliance between HDDT and the guideline-recommended regimens, however, HDDT is much safer.
