5.Advances in Research on Hepatitis B Virus DNA Integration
Virologica Sinica 2008;23(2):93-99
Since HBV DNA integration was discovered for the first time in 1980, various methods have been used to detect and study it, such as Southern Blot, in situ hybridization, polymerase chain reaction and so on. HBV DNA integration is thought to be random on the whole although some hot spots of integration were described by some researchers, one of which might be the repetitive sequences of the genomic DNA. Besides, DNA damage, especially double-strand breaks could promote HBV DNA integration into host genome. HBV DNA integration into cells may damage the stability of the genome, cause DNA rearrangement, promote DNA deletion and induce the formation of HCC.
6.A retrospective analysis of 1028 adverse events of medical device reports.
Chinese Journal of Medical Instrumentation 2013;37(6):447-450
OBJECTIVETo provide suggestion for MDAEs monitoring with analyzing the features of the 1028 reports of MDAEs.
METHODSWith retrospective case study, this paper analyzed 1 028 MDAE reports in Guiyang during 2012.
RESULTSThe intrauterine device (IUD) caused the higher proportion of adverse events with serious degree. Monitoring consciousness of grassroots users needs to be improved. The quality of the reports should be enhanced.
CONCLUSIONSMore attention should be paid to monitoring on IUD. The level of MDAEs monitoring should be improved through carrying out targeted training and publicity, establishing and improving MDAEs monitoring network.
