ABSTRACT

Based on the analysis of the traditional teaching quality evaluation system,this study designs and develops the immediately teaching and learning evaluation system with the WeChat according to the large data and formative evaluation theory.The B/S + official account of WeChat model is used to design and develop this system to realize instant feedback to the instructor,the background of real-time data analysis and early warning.This system has been applied in Southern Medical University for 2 years and has achieved good results.Due to the adoption of the widely used WeChat public number platform,the participation and evaluation of students have been improved,and the quality of teachers' teaching has improved.And through the background analysis,we find the separation of teaching and learning.

ABSTRACT

Objective@#To observe the efficacy of 755 nm picosecond laser and intense pulsed light in the treatment of facial freckles.@*Methods@#Sixty-six outpatients with freckles were randomly divided into two groups. They were treated with 755 nm picosecond laser (P755 nm) and intense pulsed light (IPL), respectively. Frequent freckles were analyzed before treatment and at 4 week after treatment.@*Results@#Both treatments had good curative effect, but the P755 nm group had better efficacy than the IPL group with significant difference.@*Conclusions@#755 nm picosecond laser and IPL can treat freckles very well, and P755 nm group is superior to IPL.

ABSTRACT

ObjectiveTo explore clinical application of selecting flap by using of digital technique in treatment of hemifacial atrophy.MethodsSeven patients with hemifacial atrophy were selected,preoperative CT angiography was performed,deformity and flap three-dimensional reconstruction and design bone and soft tissues using Mimics 14.3 software, latissimus muscular flap or femur anterolateral flap were selected,according to tilt donor area and recipient area blood vessel diameter. Defect model were printed using rapid prototyping. ResultsHemifacial atrophy had a good postoperative shape,and the flaps survived in all the 7 cases.Follow-up 3 years,the flaps look well and the patients get expecting results. ConclusionsThe digital technique was a relatively useful tool that can assist surgeons with reconstruction of the flap,and accurate marking of the extent of the flap to be harvested.Therefore avoiding intraoperative injuries to the blood vessels to better survival of the flaps.
