Objective To understand the knowledge,attitudes and impact factors related to voluntary counseling and testing(VCT)for HIV/AIDS among migrants in Minhang district of Shanghai.Method Using a convenience sampling strategy,74 migrants,27 key informants and 20 community service providers were selected to participate in in-depth interviews and focus group discussions.Results Most migrants were young,less educated and poorly aware of HIV prevention.Only one third of the migrants heard of VCT,but few of them knew where to seek VCT or had any personal VCT experience.Nearly half of the interviewees took a negative attitude towards those who participated in VCT service.The main factors influencing the participation in VCT service among the migrants were the knowledge of VCT,having risk behavior and perception,supportive environments and availability of HIV/VCT services.Conclusions There is an urgent need to promote extensive health education about HIV/VCT,adopt flexible and available approaches to VCT service and provide appropriate care following the HIV test among migrants.

Keloid is defined as special pathological scar invading adjacent healthy skin. The pathogenesis of keloid is not yet fully elucidated. Many factors such as epigenetic inheritance, inflammatory response and mechanical tension have been shown relating to keloid. In recent years, with the rapid progress of epigenetics, more and more studies on long noncoding RNA (lncRNA) have confirmed that it is closely related to keloid formation. Based on the research results of lncRNA, this article reviews its roles in formation and invasion of keloid, by analyzing the relationship between lncRNA and abnormal proliferation of fibrocytes, excessive collagen formation, cell microenvironment, cell migration and other processes.
