ABSTRACT
Abstract@#Improving health literacy can effectively reduce the risk of health risk behaviors and adverse health outcomes in children and adolescents. Global research on health literacy of children and adolescents has been increasing in recent years. The paper reviews the existing research and proposes that there is no universal definition and connotation of health literacy for children and adolescents, most of the studies use or make some revisions on the definition of adult health literacy in child and adolescent health literacy, failing to consider developmental characteristics and unique health needs of children and adolescents. Moreover, the assessment index system and instruments are diversified, making the research findings from different studies difficult to compare, and to obtain consistent and reliable conclusions. Future endeavors are encoouraged to expand health literacy researches and to update more comprehensive and practical definition, and to develop a standardized assessment instrument that can be validated in Chinese culture.
ABSTRACT
Objective To analyze the genotypes of human herpesvirus 8 (HHV-8) by using the polymorphisms in open reading frame(ORF) 26 gene in patients with squamous cell carcinoma (SCC)in Xinjiang Uygur Autonomous Region.MethodsDNA was extracted from paraffin-embeded tissue specimens from 41 patients with skin SCC and 46 patients with esophagus SCC,and subjected to nested-PCR for the amplification of the ORF26 gene of HHV-8 followed by bidirectional sequencing.Phylogenetic analysis was carried out to determine the genotype of HHV-8 by using the DNASTAR software,Clustal W program,and PHYLIP package.The data were analyzed by SPSS 17.0 software.ResultsHHV-8 DNA was detected in 9 (21.95％) of 41 skin SCC specimens and 10 (21.74％) of 46 esophagus SCC specimens (x2 =0.09,P＞ 0.05).As phylogenetic analysis showed,7 HHV-8 isolates from skin SCC specimens belonged to ORF26 subtype A,2 subtype C; 7 HHV-8 isolates from esophagus SCC specimens belonged to ORF26 subtype A,and 3 subtype C.Conclusions ORF26 subtype A and C are the predominate genotypes of HHV in patients with SCC in Xinjiang Uygur Autonomous Region,with the prevalence of subtype A higher than that of subtype C.The distribution of HHV subtypes seems unrelated to the location of SCC.
