Objective:
To investigate the changing trends in the prevalence of health literacy among rural residents in Zhejiang Province from 2016 to 2021, so as to provide the evidence for formulating the health promotion strategy in rural areas.
Methods:
Rural residents' health literacy surveillance data were retrieved in Zhejiang Province from 2016 to 2021. The prevalence of health literacy was evaluated among rural residents according to the criteria defined by Chinese Center for Health Education, and standardized by Zhejiang Provincial population data captured from the national population census in China. The 6-year cumulative increase from 2016 to 2021 was estimated to investigate the changing trends in the prevalence of health literacy.
Results:
Totally 55 568 rural residents were monitored in Zhejiang Province from 2016 to 2021, including 26 893 men (48.40%) and 28 675 women (51.60%) and 32 156 residents at ages of 45 to 65 years (57.87%). The prevalence of health literacy was 18.00%, 21.52%, 25.53%, 27.54%, 30.85%, and 34.32% among rural residents in Zhejiang Province from 2016 to 2021, appearing a tendency towards a rise (χ2trend=661.376, P<0.001), and a 16.32% 6-year cumulative increase was seen. The prevalence of basic knowledge and concept, healthy lifestyle and behaviors and basic skills all appeared a tendency towards a rise (P<0.05), with 6-year cumulative increase rates of 24.48%, 11.08% and 8.11%, respectively. Among six categories of health issues, the prevalence of chronic disease prevention, scientific health outlook and health information literacy showed a tendency towards a rise year by year (P<0.05), with 6-year cumulative increase rates of 29.73%, 21.07% and 15.98%, respectively, and the prevalence of basic medical care, safety and first aid, and infectious disease prevention literacy appeared a fluctuation (P<0.05), with 6-year cumulative increase rates of 12.85%, 6.36% and -0.47%, respectively. The prevalence of health literacy appeared an overall tendency towards a rise in rural residents with different genders, age groups, educational levels and occupations (P<0.05), with a minor 6-year cumulative increase in residents at ages of 55 years and older and farmers, while a tendency towards a decline was seen among illiterate rural residents, with a 6-year cumulative rise of -3.16%.
Conclusions
The prevalence of health literacy appeared a tendency towards a rise among rural residents in Zhejiang Province from 2016 to 2021; however, the rate of increase reduced year by year. Health education and promotion should be enhanced targeting the elderly, individuals with low educational levels and farmers.

OBJECTIVETo investigate the effect of magnesium isoglycyrrhizinate (MgIG) on allergy contact dermatitis (ACD) in mice.
METHODThe model of ACD was sensitized and challenged by 1% dinitrofluorobenzene(DNFB).48 SPF grade mice were divided into 6 groups randomly: a control group, a model group, three dosage groups and a positive group. The drug was injected through vena caudalis. The change of ear's swelling and the scores of ear's thickness and erythema of each mouse was observed. The level of INF-gamma, IgE, IL-4 in serum was detected by ELISA method. Then the pathologic change of mice ears was using HE staining examined under light microscope.
RESULTMgIG could decrease (P < 0.05) the ear's swelling, the scores of ear's thickness and erythema, and INF-gamma and IgE level in mice serum. It was observed that MgIG could significantly alleviate the infiltrate of inflam cell and the hemangiectasis in ear tissue.
CONCLUSIONCertain concentration of MgIG has significant therapeutic effect on ACD in mice. Therapeutic mechanism of MgIG may be relevant with the suppression of INF-gamma and IgE.
