Objective:To understand the current status of the level of chronic disease prevention and treatment literacy and health anxiety among chronic disease residents, as well as the urban-rural differences, in order to provide a basis for improving the level of chronic disease prevention and treatment literacy among chronic disease residents.Methods:This was a cross-sectional study. From July to August 2022, a multi-stage random sampling method was adopted to select 201 rural residents with chronic diseases in one rural health center and 242 urban residents with chronic diseases in two community health service centers. General demographic characteristics questionnaire, Chronic Disease Prevention and Control Literacy Questionnaire and Short version of Health Anxiety Scale were used for questionnaire survey.Results:There were 93 males and 108 females with chronic diseases in 201 rural chronic disease residents, and the age range was 19-69 years. There were 116 males and 126 females with chronic diseases in 242 urban chronic disease residents, and the age range was 18-69 years old. The score of chronic disease prevention and control literacy of rural chronic disease residents (7.86 ± 2.25) was lower than that of urban chronic disease residents (8.55 ± 2.03). The score of health anxiety of rural chronic disease residents (13.69 ± 5.26) was higher than that of urban chronic disease residents (11.67 ± 5.95). Both differences were statistically significant ( t=-3.43, 3.79, both P<0.05). After controlling the general demographic data, the layered linear regression analysis of rural chronic disease residents and urban chronic disease residents showed that health anxiety can negatively affect rural chronic disease residents and urban chronic disease residents of chronic disease prevention and treatment literacy level ( β=-0.185, -0.129, both P<0.05). Conclusions:There are urban-rural differences in chronic disease prevention and treatment literacy and health anxiety of chronic disease residents in community. It is necessary to strengthen psychological construction among rural chronic disease residents in order to improve their chronic disease prevention and treatment literacy.

Objective To investigate the role of caspase-1-medicated canonical pyroptosis pathway in chlorogenic acid(CGA)treatment of acute kidney injury(AKI)in mice.Method Twenty-four C57Bl/6J mice were randomized into sham-operated group,cecal ligation and puncture(CLP)group,CLP+dexamethasone group(CLP+DXM group),and CLP+CGA group(n=6)and subjected to either sham operation(laparotomy only)or CLP.After modeling the mice received intravenous infusion of 10 mg/kg normal saline(in sham and CLP groups),1 μg/kg dexamethasone or 15 mg/kg of chlorogenic acid for 6 h delivered using an intravenous pump.Eight hours after the infusion,renal morphology and histology,renal cell apoptosis,and the renal function parameters such as urea nitrogen(BUN),creatinine(Scr),and kidney injury molecule 1(KIM-1)were compared among the 4 groups;the 7-day survival rates of the mice were recorded,and the expressions of NLRP3 inflammasomes and key proteins of the caspase-1 pathway in the renal tissue were detected.Results CGA treatment significantly improved the 7-day survival rate,reduced renal pathologies of the septic mice(P<0.05),and lowered the levels of BUN,Scr,KIM-1,NLRP3 inflammasome and expressions of key proteins of the caspase-1 pathway.Conclusion CGA alleviates AKI in mice with CLP-induced sepsis by inhibiting NLRP3 inflammasomes and the caspase-1 signaling pathway.
