Objective To evaluate the effects of group medical visits and peer education on the compliance behaviors of patients with acne vulgaris,and to explore the effective health education approaches for patients with acne vulgaris.Methods A total of 80 patients with acne vulgaris were enrolled from Hospital of Dermatology,Chinese Academy of Medical Sciences during December 2016.They were randomly and equally divided into 2 groups:intervention group receiving conventional health education combined with group medical visits and peer education,and control group receiving conventional health education alone.At week 1,2 and 4 after the intervention,the compliance behaviors were compared between the 2 groups.Results Totally,18 patients were lost to the follow-up due to refusals and non-response,and 32 patients in the intervention group and 30 patients in the control group finally completed the study.At week 1,2 and 4 after the intervention,the scores of compliance behaviors were significantly higher in the intervention group (83.6 ± 9.3,85.9 ± 9.1,91.2 ± 8.4 respectively) than in the control group (77.1 ± 7.3,77.1 ± 8.6,79.1 ± 10.2 respectively;all P ＜ 0.05).Moreover,the scores of compliance behaviors significantly increased over time (P ＜ 0.05),and there was a significant interaction effect between the intervention methods and treatment duration (P ＜ 0.05).Conclusion Health education approaches including group medical visits and peer education can improve the compliance behaviors of patients with acne vulgaris.

Cyanobacteria is one of the promising microbial chassis in synthetic biology, which serves as a typical host for light-driven production. With the gradual depletion of fossil resources and intensification of global warming, the research on cyanobacterial cell factory using CO2 as carbon resource is ushering in a new wave. For a long time, research focus on cyanobacterial cell factory has mainly been the production of energy products, such as liquid fuels and hydrogen. One of the critical bottlenecks occurring in cyanobacterial cell factory is the poor economic performance, which is mainly caused by the inherent inefficiency of cyanobacteria. The problem is particularly prominent for these extremely cost-sensitive energy products. As an indispensable basis for modern industry, polymer monomers belong to the bulk chemicals with high added value. Therefore, increasing attention has been focused on polymer monomers which are superior in overcoming the economic barrier in commercialization of cyanobacterial cell factories. Here, we systematically review the progress on the production of polymer monomers using cyanobacteria, including the strategies for improving production, and the related technologies for the application of this important microbial cell factory. Finally, we summarize several issues in cyanobacterial synthetic biology and proposed future developing trends in this field.
