ABSTRACT

Objective:To explore the application effect of small private online course (SPOC) teaching mode in clinical practice teaching of thoracic surgery.Methods:A total of 56 undergraduate students who were internships from May to July 2018 were selected as subjects. They were randomly divided into experimental group and control group. SPOC teaching mode and traditional teaching mode were respectively adopted in the practice teaching, and the teaching effect was evaluated by questionnaires and written examinations. SPSS 22.0 was used for statistical analysis, ttest for independent-sample test, and chi-square test for counting data. There were significant differences when P<0.05. Results:The questionnaire showed that the six teaching effect evaluation indicators of the experimental group were higher than those of the control group ( P<0.01). In terms of written test assessment, the average score of the experimental group was significantly higher than that of the control group, with significant differences ( P<0.05). Conclusion:The SPOC teaching mode can improve the teaching effect of clinical practice in thoracic surgery and improve students' self-learning ability.

ABSTRACT

Objective To explore the role of Yes-associated protein 1 (YAP1) in the proliferation,cell cycle,migration and invasion of human non-small cell lung cancer (NSCLC) cells.Methods A lenti-siRNA targeting YAP1 (si-YAP1) was used to inhibit the expression of YAP1 gene of human NSCLC cell line A549 cells.CCK-8 assay and flow cytometry were used to determine the effects of silencing of YAP1 expression on A549 cells proliferation and cell cycle,respectively;Transwell assay was used to observe the effect of silencing of YAP1 expression on A549 cell migration and invasion.Results After infection with si-YAP1,the expressions of YAP1 mRNA and protein in A549 cells were significantly down-regulated (P<0.01).YAP1 silencing significantly inhibited A549 cell proliferation,increased the percentage of cells in G0/G1 phase (P<0.01),and significantly decreased the migration and invasion of A549 cells (P<0.01).Conclusion YAP1 silencing can inhibit malignant biological characteristics of NSCLC,which suggests that YAP 1 gene may serve as an important target in the gene therapy of lung cancer.

ABSTRACT

0.05). In the control group, the intima of grafted veins were thickened evidently with proliferated vascular smooth muscle cells (VSMCs) and the media thickness were slight. Compared with the control group, the intima was slightly thickened in the treatment group, but there were significant reductions in proliferated VSMCs. Additionally, the media thickness was unobvious in treatment group. Compared with the control group, the thickness and area of neointima and the expression of PCNA in the treatment group were significantly lower than those in the control group (P
