以承德石油高等专科学校为例,分析了应用型本科学生的学情和信息素养现状,结合网络教学手段,以需求为导向,探讨了应用型本科专业科技文献检索课的教学改革措施。分别对教学内容、教学模式、教学方法进行改革,增加实用性强的网络信息检索教学内容,教学全程使用移动教学平台、在线考试及存储平台实现无纸化教学和考核,教学章节设计中分别采用翻转课堂、嵌入式教学、案例教学法、问题教学法、互动教学法等方式方法提升受教者的学习兴趣,教学改革效果良好,满足了学生的信息需求。

Objective： To prove the quality of propofol or sevoflurane general anesthesia in children based on preoperative and postoperative levels of blood sugar,transaminases and creatinine. Methods： Our study was a randomized controlled trial. Two hundred ASA physical I pediatric patients aged 4 to 7 years,the time less than 60 min of elective surgery under general anesthesia,were randomized in two groups based on different approaches： total intravenous anesthesia was used for the propofol group（ n = 100）（ TIVA） and the inhalation technique was used for the sevoflurane group（ n = 100）. Blood sugar,transaminases and creatinine were detected and recorded at pre and post operation. Results： There were on significantly different between the two groups in blood sugar,transaminases（ ALT,AST） and creatinine at preoperative and postoperative（ P 0. 05）. Conclusion： Analysis of the examined laboratory parameters shows that propofol and sevoflurane provide full security of general anesthesia in pediatric patients.
