ABSTRACT
Objective@#To investigate the level and influencing factors of health literacy among the elderly in Gannan Tibetan Autonomous Prefecture, Gansu Province, so as to provide the evidence for developing the strategy to improve health literacy among the elderly. @*Methods@#A total of 3 125 residents at ages of 60 years and older were recruited from Gannan Tibetan Autonomous Prefecture with a multistage random cluster sampling method from June to September, 2021. The level of health literacy was investigate among the elderly using the Questionnaire on the Health Literacy among Chinese Residents, and factors affecting the health literacy were identified using a multivariable logistic regression model. @*Results@# A total of 3 125 questionnaires were allocated and 3 022 valid questionnaires were recovered, with an effective recovery rate of 96.70%. The respondents included 1 562 men (51.69%) and 1 460 women (48.31%), and had a mean age of (67.37±5.78) years. The participants included 1 234 individuals with an ethnic minority (40.83%). The overall prevalence of health literacy was 5.99% among participants, and the prevalence rates of basic healthy knowledge and attitudes, healthy lifestyles and behaviors and basic health-related skills were 13.57%, 8.97% and 7.67%, respectively. Multivariable logistic regression analysis identified Han Ethnicity (OR=2.266, 95%CI: 1.497-3.431), educational level (illiteracy/semi-illiteracy, OR=0.097, 95%CI: 0.038-0.246; primary school, OR=0.125, 95%CI: 0.051-0.303; junior high school, OR=0.276, 95%CI: 0.113-0.672; high school/vocational high school/technical secondary school, OR=0.307, 95%CI: 0.125-0.757), enterprise workers (OR=1.791, 95%CI: 1.089-2.947) and annual household income of less than 10 000 RMB (OR=0.526, 95%CI: 0.294-0.940) as factors affecting health literacy among the elderly in Gannan Tibetan Autonomous Prefecture. @*Conclusions@#The level of health literacy is low among the elderly in Gannan Tibetan Autonomous Prefecture, and ethnicity, educational level, occupation and annual household income are main factors affecting the level of health literacy among the elderly in Gannan Tibetan Autonomous Prefecture.
ABSTRACT
ABSTRACT Objectives: This study aimed to explore the effects of miR-128b in the regulation of Lipopolysaccharide (LPS) induced apoptosis. Methods: Human Pulmonary Microvascular Endothelial Cells (HPMECs) were transfected with an miR-128b inhibitor and stimulated with LPS for 24 h. FCM was performed to detect apoptosis and Reactive Oxygen Species (ROS) production. In addition, miRNA and caspase-3 expression levels were determined using real-time quantitative polymerase chain reaction and western blotting. Results: LPS significantly induced apoptosis and ROS production and upregulated miR-128b and caspase-3 expressions in HPMECs. However, LPS-induced effects were suppressed when an miR-128b inhibitor was used. Preincu-bation with NAC decreased the LPS-induced apoptosis of HPMECs. Conclusions: These effects were mediated by miR-128b via the caspase-3 pathway.
