ABSTRACT
ObjectiveThe aim is to understand the current situation of death literacy among Chinese residents in the Guangdong-Hongkong-Macao Greater Bay Area and explore educational approaches to enhance the death literacy of the social public. MethodThe Death Literacy Index was conducted among 2，002 residents in the Guangdong-Hong Kong-Macao Greater Bay Area， which included 29 items from four dimensions namely practice， experience， fact， and community. ResultsThe average score of death literacy among the respondents was moderate （6.70）， with scores for practical and experiential knowledge （7.32， 7.50） higher than those for factual and community knowledge （6.20， 6.10）. The weakest content included discussing bereavement with people who have just lost loved ones （5.07）， laws and regulations related to death at home （5.35）， and providing support for the terminal person and their families in the community. ConclusionThe death literacy of the Chinese residents in the Greater Bay Area was moderate， in which community knowledge was the weakest with a lack of concern and support for the terminal person and the caregivers. Therefore， community health promotion strategies were proposed to strengthen death education for the public and promote the death literacy of the residents.
ABSTRACT
Objective The study was to evaluate the behavioral differences in learning and memory abilities among three ani -mal models of Alzheimer′s disease. Methods Three SD rat models(n=20) were used in this study.The first SD rat model was es-tablished by intracerebral injection of Aβ25-35 into the bilateral hippocampus , the second mouse model was induced by intraperitoneal in-jection of scopolamine and the third was a senescence accelerated mouse model .Morris Water maze test was performed to investigate behavioral differences by comparison to corresponding blank control groups ( sham operation group , blank group and P8 group ) . Results The learning and memory abilities of senescence accelerated rats and scopolamine -treated rats were worse than those of the corresponding control groups, especially the scopolamine-treated rat ([35.47 ±3.78]s vs [50.61 ±3.94]s, P0.05). Conclusion The model of Alzheimer′s disease in-duced by intraperitoneal injection of scopolamine represents more distinct changes in learning and memory abilities .Morris water maze test can be used to well evaluate whether the scopolamine-induced model is successfully established or not .
