Objective:
To learn the health literacy status, trend and associated factors of Ningbo residents from 2015 to 2019, so as to provide basis for developing health policies and interventions.
Methods:
The monitoring data of health literacy of Ningbo residents from 2015 to 2019 was collected. The health literacy level was calculated and standardized by the population data of the sixth national census of Ningbo in 2010; five-year absolute growth and growth rate were used to reflect the changing trend. Multivariate logistic regression model was employed to analyze the influencing factors for the health literacy level.
Results:
The health literacy levels from 2015 to 2019 were 15.44%, 21.73%, 22.41%, 27.60% and 30.03%, with an annual increase trend ( P<0.05 ). The five-year absolute growth and growth rate were 14.59% and 94.49%. The Results of multivariate logistic regression analysis indicated that the year ( OR=1.158, 95%CI: 1.132-1.184 ), age ( 25-<35岁 years, OR=1.235, 95%CI: 1.039-1.468; 35-<45岁 years, OR=1.416, 95%CI: 1.193-1.681; 45-<55岁 years, OR=1.221, 95%CI: 1.024-1.455 ) , education level ( primary school, OR=1.790, 95%CI: 1.461-2.195; junior high school, OR=2.574, 95%CI: 2.102-3.154; high school/vocational high school/technical secondary school, OR=4.863, 95%CI: 3.943-5.998; college or above, OR=8.829, 95%CI: 7.109-10.965 ) , urban areas ( OR=0.934, 95%CI: 0.874-0.998 ) and occupation ( farmers, OR=0.692, 95%CI: 0.608-0.787; workers, OR=0.746, 95%CI: 0.664-0.837; enterprise staff, OR=0.822, 95%CI: 0.745-0.906; others, OR=1.106, 95%CI: 1.009-1.211 ) were the influencing factors for health literacy level.

Objective To evaluate the efifcacy and safety of Xiyanping in the treatment of hand-foot and mouth disease. Methods Based on the principles and methods of Cochrane systematic reviews, Cochrane Library, PubMed, Medline, Chinese Bio-medicine Database (CBM), China Journal Full-text Database (CNKI), VIP database and Wanfang database were searched. All of the randomized controlled trials (RCT) of Xiyanping versus ribavirin were included. The data were extracted and evalu-ated by two reviewers independently. Risk assessment tool was used to assess the risk of bias and software Revman5.0 was used for meta-analysis. Results Twenty-four RCT and 3314 patients were included. Comparing to ribavirin, Xiyanping showed better therapeutic outcomes regarding to total effective rate, durations of fever and rash elimination (RR=1.17, 95%CI:1.12~1.23;MD=-1.56, 95%CI:-2.10~-1.02;MD=-1.41, 95%CI:-1.90~-0.93). Side effects were rare in both groups and could be recovered after drug withdrawal. Conclusions The current evidence suggests that Xiyanping is superior to ribavirin in the treatment of hand-foot and mouth disease.

Objectives To explore the relevant factors of liver X receptor (LXR) and lipid metabolism in school-age chil-dren with obesity. Methods A total of 80 obese children were selected by indexes of physical growth from pupils in Grades 1-6, aged 7-14 years from June 2011 to October 2011. Fifty-one age and sex matched children with normal BMI were chosen as nor-mal controls. The metabolic indexes including aspartate transaminase (AST), alanine aminotransferase (ALT), glutamyl transpep-tidase (GGT), total cholesterol (CHOL), triacylglycerol (TG), high density lipoprotein cholesterol (HDL-C), low density lipopro-tein cholesterol (LDL-C) and expression of LXR were detected in fasting blood. Results The expression level of LXR in obese children (9.14 ± 1.15) was higher than that in control children (2.84 ± 3.68) with significant difference (t=4.55,P=0.000). Eighty percent (80%) of obese children were LXR>1 (64/80) which was higher than that of control children (23/51, 45.1%), and signifi-cant difference was found between the two groups (χ2=17.01, P=0.000). Compared to controls, the levels of AST, ALT, GGT, CHOL, TG and LDL-C were higher while the level of HDL-C was lower in obese children (P<0.05). The correlation analysis found that AST, ALT, CHOL, LDL-C and BMI were positively correlated with LXR (r=0.18~0.26,P<0.05). Logistic regression ana-lysis showed that AST≥40IU/L (OR=1.076), ALT≥40IU/L (OR=1.036), CHOL≥5.20 mmol/L (OR=2.038), LDL-C≥3.36 mmol/L (OR=2.176) and BMI≥18.9 kg/m2 (OR=1.131) were risk factors for LXR>1 (P<0.05). Conclusions Obesity in school-age chil-dren can up-regulate the expression of liver X receptor and cause liver damage and abnormal lipids metabolism.
