ABSTRACT
ObjectiveTo investigate the current status of sleep quality among adult residents in urban areas of Mianyang， and to explore the influencing factors. MethodsA cross-sectional survey was conducted on 126 adult residents from three communities in Mianyang. The selected individuals were assessed using self-made general information questionnaire， Pittsburgh Sleep Quality Index （PSQI）， the sleep-hygiene awareness activities subsection and sleep-hygiene practice sections of Sleep Hygiene Awareness and Practice （SHAP）. Then the sleep quality among residents of different demographic characteristics， sleep-hygiene awareness activities and sleep-hygiene practices was compared， meantime， the influencing factors of sleep quality were screened via multiple linear regression model. ResultsThe PSQI score was （7.51±4.05） among urban adults in Mianyang. Correlation analysis yielded that the sleep-hygiene awareness score was positively correlated with the daytime dysfunction dimension score in PSQI （r=0.232， P=0.009）， and the sleep-hygiene habit score was positively correlated with PSQI score， the dimension scores of sleep latency， sleep quality， sleep duration， use of sleeping medication and daytime dysfunction （r=0.188~0.362， P<0.05 or 0.01）. Regression analysis showed that sleep-hygiene habit was the influencing factor of sleep quality （P<0.01）. ConclusionThe sleep quality among adult residents in urban areas of Mianyang needs to be improved， moreover， sleep-hygiene habit is a key factor affecting sleep quality.
ABSTRACT
As the morbidity of metabolic syndrome like obesity and diabetes increases rapidly worldwide, the issue of nutrition (functional food) and health has drawn more attention. D-psicose, a rare natural ketohexose, has become a hot topic in functional food and health-care field because of its hypoglycemic and hypolipidemic function with good sweetness. This article mainly discusses the functional properties and biosynthesis research progress of D-psicose, together with the crystal structure of ketose-3-epimerase, to provide theoretical guidance for D-psicose-producing strain screening as well as improving the thermostability and catalytic efficiency of ketose-3-epimerase for industrial application.
ABSTRACT
This review is intended to present the latest information on the pathogenesis of diabetic nephropathy based on the studies of recent years,involving potential therapeutic targets of diabetic nephropathy,such as hemodynamic dysfunctions,advanced glycation end-product,lipid metabolism disorders,inflammatory cytokines,and oxidative stress. Further studies are mandatory to investigate the effect of various interventions that modulate the pathogenesis in the treatment of diabetic nephropathy.
