Objective:To explore the effects of the scaffolding-based flipped classroom approach in the teaching of Infectious Disease Nursing. Methods:We assigned 152 students of nursing and midwifery majors of grade 2018 (experimental group) to be taught using the scaffolding-based flipped classroom approach and 182 students of grade 2017 (control group) to be taught using the traditional lecture method. Teaching effects were evaluated through students' exam performance and a questionnaire survey. Numerical data were analyzed using the χ2 test and t test with the use of SPSS 18.0, and text data were processed using NVivo 11 for thematic analysis. Results:The experimental group and control group showed significant differences in the interim exam score (83.19±7.96 vs. 79.62±3.14, P<0.001) and final exam score (78.47±6.92 vs. 73.16±8.24, P<0.001). The students of grade 2018 had a high level of participation in online learning. The questionnaire results showed that the scaffolding-based flipped classroom was well recognized in terms of students' overall perception, perceived course quality, perceived value of learning, and satisfaction and the open-ended question, with low scores for learner complaints and loyalty. Conclusions:The scaffolding-based flipped classroom is feasible in the teaching of Infectious Disease Nursing, which can improve students' academic performance and overall competence.

OBJECTIVE: To investigate the periodontal status in patients with oral submucous fibrosis (OSF), and to provide reference for the treatment and prophylaxis in patients with OSF and betel chewers. METHODS: Fifty samples clinically and pathologically diagnosed as OSF patients were selected as the OSF group, another 50 age-matched healthy volunteers in the similar living condition were compared with the OSF patients and non-betel nut chewers were classified as the control group. The 5 periodontal clinical parameters were collected and recorded, including plaque index, periodontal probing depth, clinical attachment loss, gingival index, and tooth count of bleeding of probing. RESULTS: There was a significant difference in plaque index (PLI) between the OSF group (2.14+/-0.64) and the control group (1.7+/-0.89) (P<0.01). Periodontal probing depth (PD) was (1.98+/-0.70) mm in the control group, and (5.57+/-2.39) mm in the OSF group, with significant difference in PD (P<0.01). There was no significant difference in clinical attachment loss, gingival index, and tooth count of bleeding on probing between the 2 groups (P>0.05). CONCLUSION OSF patients tend to accumulate plaque, and have deep periodontal pocket, periodontal inflammation or severe periodontal damage.
