OBJECTIVE:To construct the structure equation model for the burden of chronic disease inpatients in primary hos-pital before and after the implementation of zero price policy,and analyze the changes of burden factor loading. METHODS:6 pri-mary hospitals were randomly selected in Danyang,Jiangsu province. The data of hospitalization expenses for chronic diseases(hy-pertension,diabetes,bronchitis)were collected before and after the implementation of zero price policy. Using drug cost,nursing fees,inspection fees and treatment fees as independent variables,hospitalization burden as latent variable,SPSS and AMOS 24.0 software were adopted to establish the model. RESULTS:The burden factor loading of inpatients changed greatly before and after the implementation of zero price policy. χ2=24.586,χ2/df=1.446, RMSEA=0.019,GFI=0.995,AGFI=0.989,CFI=0.988,NFI=0.963 manifested good model fitting. Factor loading of drug cost increased greatly,indicating the burden of inpatients was reduced after the implementation of zero price policy. Factor loading of inspection fees and treatment fees increased significantly,the charac-terization effects of them to the burden of inpatients were enhanced. Factor loading of nursing fees was the lowest,and it had the weakest effects on the burden of inpatients,of which the government should enhance the regulation. CONCLUSIONS:Established model has good reliability and validity. It can reflect the change of burden factor loading of inpatients before and after the implemen-tation of zero price policy.

Objective: To investigate the effect of urolithin A (UA) on liver insulin signaling pathway in type 2 diabetes model mice and its relationship with autophagy. Methods: C57BL/6 mice were randomly divided into four groups according to body weight, namely control group, model group, UA (50 mg/kg) group, UA (50 mg/kg) combined with chloroquine (50 mg/kg) group. After 6 weeks of high-fat diet, a type 2 diabetes model was established by ip streptozotocin (STZ). The mice in each group were ig administrated for 7 weeks, and their body weight, water intake, blood lipids, fasting blood glucose (FBG), and fasting insulin (FINS) levels were measured; HE staining was used to observe pathological changes in mouse liver tissue; Western blotting was used to detect mouse phosphorylated protein kinase B (p-Akt), glucose transporter 2 (Glut2), phosphorylated glycogen synthase kinase-3β(p-GSK3β) and autophagy-related protein microtubule-related protein 1 light chain 3 II/I (LC3II/I) and selective autophagy linker protein (p62) expression levels. Results: Compared with the model group, UA significantly improved liver tissue steatosis and edema in diabetic model mice, significantly reduced plasma triacylglycerol, free fatty acids, low-density lipoprotein-cholesterol, FBG, FINS levels, and increased high-density lipoprotein-cholesterol level (P < 0.01); UA significantly reduced HOMA-IR and increased ISI (P < 0.01), up-regulated the protein expression of p-Akt, Glut2, p-GSK3β, and LC3II/I in liver tissues, and inhibited the expression of p62 protein (P < 0.01). Combined with chloroquine, FBG, FINS, and HOMA-IR in mice were increased, and ISI was decreased (P < 0.05); Liver tissue edema and steatosis were significantly aggravated; The expression levels of p-Akt, Glut2, LC3II/I protein in liver tissue were decreased, and p62 protein expression levels were increased (P < 0.05), indicating that the autophagy inhibitor chloroquine significantly weakened the effect of UA. Conclusion: UA may improve liver insulin resistance in diabetic mice by activating liver autophagy.
