Results Analyzing the 10 questionnaires, G1 (video group) obtained a median result of 82 exact answers (74-97), whereas G2 (textbook group) obtained a median result of 64.2 correct answers (53-79). Analyzing statistically the results of two groups, using unpaired t-Student's test with a level of statistical significance >95%, the results of G1 were statistically significantly better that G2 with a P = .0265 for the average scores. Conclusion Video-based coaching to learn surgical techniques is a novel, feasible, and excellent modality for supplementing surgical techniques learning for pediatric surgery trainees. Objective evaluation using a multianswered questionnaire demonstrates that video-based coaching in pediatric surgery is statistically better than textbook classic education. We suggest to adopt this teaching modality in every surgical training program above all to teach MIS and robotic surgery.PM2.5 plays an important role in the physiological and pathological progression of lung cancer. Lentinan exerts antitumor activity in many kinds of human cancers. Plasmacytoma variant translocation 1 (PVT1) exerts antitumor activity in many kinds of human cancers. However, the role and underlying molecular mechanism of PVT1 in the role of lentinan in PM2.5-exposed lung cancer are still largely unknown. Our study confirmed that PM2.5 exposure induced the production of inflammatory factors, epithelial-mesenchymal transition (EMT) and migration of lung cancer cells. Lentinan exerted antitumor effects by inhibiting the production of inflammatory factors, EMT, and migration of lung cancer cells. Lentinan suppressed PM2.5 exposure-induced cellular progression by inhibiting the PM2.5 exposure-induced elevation of PVT1 expression. PVT1 absorbed miR-199a, and miR-199a inhibited caveolin1 expression and thus formed the PVT1/miR-199a/caveolin1 sign
