Patient safety education among chinese medical undergraduates: An empirical study / 华中科技大学学报（医学）（英德文版）

Patient safety education is conducive to medical students' cognition on patient safety and to improvement of medical quality and safety. Developing patient safety education for medical students is more and more widely recognized by World Health Organization and countries all over the world. However, in China, patient safety courses aiming at medical students are relatively few, and there are few reports about the effect of patient safety courses. This paper explored the influence of patient safety curriculum on medical students' attitude to and knowledge of patient safety. The patient safety curriculum was carried out for 2011-grade undergraduates of Tongji Medical College, Huazhong University of Science and Technology. The students participated in the class according to free choice. After the curriculum, the information of gender, major, attended course, attitude toward patient safety, and knowledge of laws and regulations of the 2011-grade undergraduates were collected. After rejecting invalid questionnaires, the number of undergraduates that participated in the survey was 112 (61 students did not take part in the curriculum; 51 took part in). Chi-square test was applied to analyze patient safety education's influence on medical students' attitude to patient safety and their knowledge mastery situation. The influence of patient safety education on the attitude of medical students to patient safety was not significant, but that on their knowledge of patient safety was remarkable. No matter male or female, as compared with medical students who had not accepted patient safety education, they both had a better acquisition of knowledge after having this education (for male students: 95% CI, 4.556-106.238, P<0.001; for female students: 95% CI, 3.183-33.238, P<0.001). Students majoring in Western Medicine had a relatively better mastery of knowledge of patient safety after receiving patient safety education (95% CI, 6.267-76.271, P<0.001). Short-term patient safety education cannot change medical students' stereotyped cognition on matters related to patient safety, but it can effectively enhance their knowledge of laws and regulations of patient safety.

Role of focal adhesion kinase in the hypoxia-induced invasion of SMMC-7721 cells / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To study focal adhesion kinase (FAK) expression in hypoxia-stressed SMMC-7721 cells and the role of FAK expression in the hypoxia-induced invasion of SMMC-7721 cells.</p><p><b>METHODS</b>SMMC-7721 cells were cultured in 21% O2 or 1% O2. FAK expression was determined by Western blot. The siRNA expression vector pshRNA-FAK targeting to FAK and the control vector pGensil-2 were transfected into SMMC-7721 cells. The hypoxia-induced migration and invasion ability of SMMC-7721 cells transfected with pshRNA-FAK were analyzed. In normoxia, invasion of SMMC-7721 cells transfected with pcDNA3-FAK was analyzed.</p><p><b>RESULTS</b>The expression of FAK was increased significantly in SMMC-7721 cells 24 h after hypoxia stress (P<0.01). The level of FAK protein was decreased by 74.6%+/-5.1% after the pshRNA-FAK transfection in normoxia and hypoxia. The migration and invasion of SMMC-7721 cells was increased in 1% O2 (P<0.01). However, the migration and invasion of SMMC-7721 cells transfected with pshRNA-FAK was decreased in 1% O2 (P<0.05). Overexpression of FAK significantly stimulated the invasion of SMMC-7721 cells.</p><p><b>CONCLUSION</b>Up-regulation of FAK may play an important role in the invasion of SMMC-7721 cells induced by hypoxia.</p>

Relationship between mucosal surface patterns under enhanced magnification endoscopy and pathological epithelial types of Barrett esophagus / 中华消化内镜杂志

Objective To evaluate the enhanced magnification endoscopy in the diagnosis of Barrett esophagus,and to explore the relationship between mucosal surface patterns and pathological epithelial types of Barrett esophagus.Methods Enhanced magnification endoscopy was performed 'after spraying 2%-3% acetic acid on the surface of distal esophagus in 40 Barrett esophagus patients.Mucosal specimen were biop- syed.Results According to the mucosal types of Toyoda in 2003,there were three mucosal types:Ⅰ dot pat- tern 7(17.5%),5 of 7(71.4%)fundie type,Ⅱ reticular pattern 24(60.0%),16 of 24(66.7%)fundic type,Ⅲ cerebroid/villous 9(22.5%),intestinal metaplasia or dysplasia.Conclusion Enhanced magnifi- cation endoscopy helps to identify areas with intestinal metaplasia and dysplasia,and is useful in the diagno- sis of Barrett esophagus.
