<b><i>Introduction:</i></b> Alzheimer’s disease (AD), which is characterized by abnormal deposition of amyloid-β (Aβ) plaques and impaired neurogenesis and cognition, still lacks an optimally effective therapeutic agent for its management, and mounting evidence has shown that inflammatory processes are implicated in AD. Sophocarpine has been reported to exert inflammation-regulating effects in various diseases. However, whether sophocarpine can exert anti-neuroinflammatory and neuroprotective effects in AD remains unclear. This study investigated whether sophocarpine could ameliorate the pathological features and potential mechanisms in a mouse AD model. <b><i>Methods:</i></b> APP/PS1 mice were treated with sophocarpine for 8 weeks. We quantified the effects of sophocarpine treatment on cognitive performance using a behavioral test. Brain Aβ deposits and neurogenesis were evaluated using immunofluorescence staining. We also assessed the morphology and inflammatory changes induced by sophocarpine administration and its expression in the hippocampus. <b><i>Results:</i></b> Administration of sophocarpine significantly alleviated cognitive impairment and reduced neural loss. APP/PS1 mice treated with sophocarpine showed reduced Aβ plaque deposits and enhanced neurogenesis. Sophocarpine markedly decreased the expression of inflammation markers and inhibited microglial activation. <b><i>Conclusions:</i></b> Sophocarpine could potentially alleviate cognitive impairment and brain damage in APP/PS1 mice with its neuroprotective effects via modulation of the inflammatory pathway.
Context: In the event of accidental trauma, incurable disease and public health emergencies, young adults are unable to participate in their own medical decisions, family members face the huge decision-making pressure and medical resources of the society were unevenly distributed. Objective: The purposes of this study is to investigate the Advanced Care Planning (ACP) acceptance and examine its influencing factors using sequential explanatory mixed methods in order to provide a basis for the formulation of later interventions. Methods: A cross-sectional study of young adults (N = 785) and 12 other young adults from two other communities were investigated from January 2021 to February 2022. Descriptive statistics and multiple linear regressions were conducted. Content analysis was performed on the qualitative data. Results: The primary factors that contributed to the acceptance of ACP were the natural acceptance of death, being female, having a high level of education, having a loved one diagnosed with a chronic disease, and having heard of ACP. Among young adults, the acceptance of ACP may be impeded by a fear of the unknown nature of death, a poor understanding of ACP, and family-led decision-making. Discussion: Our study found that 77.1% had not heard of ACP before participating in the study and showed potential to accept ACP-related interventions. The study highlighted the importance of implementing regular young adult education courses, promoting routine ACP knowledge, individualized education, discussing family member’s disease experiences, conducting family meetings, and identifying young adult responsibilities and roles in implement ACP for young adults in China.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
