Flipped classroom teaching method based on micro-lecture in bedside teaching of standardized training in pediatric residents / 中华医学教育探索杂志

Objective:To explore the effect of flipped classroom teaching method based on micro-lecture in bedside teaching of standardized training in pediatric residents.Method:s A total of 30 residents in pediatric rotation were selected as subjects, with 15 subjects in each group. The students in the experimental group carried out the bedside teaching of "flipped classroom based on micro-lectures", while the students in the control group carried out traditional teaching rounds. The bedside teaching of the two groups were conducted every two weeks, and the same cases were selected with the same instructors. Both groups completed the quizzes before the bedside teaching. After six months' training, the difference of training effect between the two groups was compared through the examination (case analysis and clinical skills).Result:s The scores of the quizzes in the experimental group were significantly higher than those in the control group ( P<0.05). The scores of case analysis and clinical skills in the experimental group were significantly higher than those in the control group ( P<0.05), and logical thinking and doctor-patient communication abilities in the experimental group were significantly better than those in the control group( P<0.05). The results of the questionnaire survey in the experimental group showed that the students believed that the new bedside teaching method could promote learning initiative, help to inspire clinical thinking and improve doctor-patient communication abilities. Conclusion:Flipped classroom teaching method based on micro-lecture in bedside teaching of pediatric residents not only strengthens their basic theoretical knowledge, but also improves their clinical skills, especially in establishing correct clinical thinking and mastering doctor-patient communication skills.

Expressions of tissue factor and tissue factor pathway inhibitor in patients with acute graft-versus-host disease after allogeneic hematopoietic stem cell transplantation / 华中科技大学学报（医学）（英德文版）

This study examined the expressions of human serum tissue factor (TF) and tissue factor pathway inhibitor (TFPI) in patients with acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and their clinical significance. The serum TF and TFPI levels were detected by ELISA in 28 allo-HSCT recipients before and after the transplantation and the changes of TF and TFPI levels were dynamically monitored at different phases of the disease. No significant differences in the serum TF and TFPI levels were found in allo-HSCT recipients in the absence of aGVHD or with grade I aGVHD before and after the transplantation. The levels of serum TF and TFPI were substantially increased in the patients with gradeII aGVHD at the peak of aGVHD (P0.05) and the TF level was lowered but still higher than the baseline level (P<0.05). It was concluded that the levels of serum TF and TFPI were increased significantly in the patients with grade II-IV aGVHD after allo-HSCT and decreased markedly after the treatment. Monitoring the levels of serum TF and TFPI in the patients with allo-HSCT is important to predict the occurrence, outcome and prognosis of aGVHD.
