Teaching of Chongqing Institute of Engineering"

With the advent of the"Internet+"era and the development of educational informatization,smart teaching will become an important form of education and teaching.This paper starts with the concept and characteristics of smart teaching and takes the course"Innovation and Entrepreneurship Foundation"as an example.Based on the platform of"Smart Teaching of Chongqing Institute of Engineering",smart teaching practice and research is carried out in four stages:pre-class teaching,in-class teaching,after-class teaching,and teaching evaluation.The practice has proved that this new teaching mode realizes the complementary advantages of online and offline teaching,stimulates students'interest and initiative in learning,improves the teaching quality of the course,and has good application value.

Cumulative probability and risk analysis for Nd:YAG laser capsulotomy

AIM: To estimate the cumulative probability of Nd:YAG capsulotomy at a teaching institution and evaluate secondary risk factors.METHODS: The records of all patients who underwent phacoemulsification with intraocular lens(IOL) placement between 2005-2010 were retrospectively reviewed. The cumulative probability of Nd:YAG capsulotomy(capsulotomy) was calculated using KaplanMeier survival analysis and secondary risk factors were evaluated using the Cox proportional hazards regression model. RESULTS: One thousand three hundred and fifty four charts were reviewed. A total of 70 capsulotomies wereperformed. The mean follow-up was 19.4 mo(standard deviation 17 mo). The cumulative probability of capsulotomy was 4% at 1 year, 5% at 2 year, and 9% at 3 year. Multivariate analysis demonstrated an increased risk with younger age(HR = 1.03, CI 1.01-1.05, P = 0.007), placement of sulcus IOL(HR = 2.57, CI 1.32-4.99, P = 0.005), ocular trauma(HR = 2.34, CI 1.13-4.83, P = 0.02), and phacoemulsification by a more experienced surgeon(HR = 4.32, CI 1.89-9.87, P = 0.001).CONCLUSION: Cumulative probability of capsulotomy was lower than previously reported. Posterior capsule opacification was strongly associated with younger age and factors associated with high-risk cataract surgery. Surgeon awareness to the risk factors that correlate with posterior capsulotomy may allow for more thorough pre-operative disclosure and enhance patient satisfaction.
