Neglect of preschool children in urban area of Xi an under the background of multi-child policy / 中国学校卫生

Objective@#To understand the situation of neglect of preschool children in the urban area of Xi an under the background of multi child policy, so as to provide a reference for making effective prevention.@*Methods@#In Novmber 2022, according to the multi stage stratified cluster sampling principle, 2 450 parents of children aged 3-6 years were randomly selected from 7 urban areas of Xi an to participate in the questionnaire survey. A questionnaire survey was conducted using the "Neglect Evaluation Norms of 3-6 Years Old (Preschool) Children in Urban Areas of China". SPSS 18.0 software was used for statistical description, Chi square test and variance analysis.@*Results@#The total neglect rate of preschool children in the urban area of Xi an was 29.0% and the total neglect score was (37.58±8.44). There was no statistical difference in the neglect status of children in different grade groups ( χ 2/ F =1.61, 2.98, P >0.05). The neglect score of boys was higher than girls ( t =2.45, P <0.05). There was no statistical difference in the neglect rate and neglect score of boys and girls in other levels ( P >0.05); except for the significant difference in the neglect degree of medical treatment, education and safety ( t =2.01, 2.28, 2.02, P <0.05). The rate and score of neglect in multi-child families were higher than only-child families ( χ 2/ t = 13.68, -4.54, P <0.05). There were significant differences in the rate and degree of neglect of children with different birth order, which were "third and fourth-born>second-born>first-born" ( χ 2/ F = 10.84 , 2.79, P <0.05). The neglect rate and score of "single parent family" were significantly higher than that of "nuclear family" and "three-generation family" ( χ 2/ F =4.78, 2.79, P <0.05).@*Conclusion@#The neglect situation of preschool children in urban area of Xi an is still serious, especially in multi-child families. It should actively explore the risk factors and formulate effective intervention measures.

Progress on the role of Toll-like receptors in Candida albicans infections / 浙江大学学报·医学版

Toll like receptors (TLRs) are expressed mainly on innate immunocytes such as dendritic cells and macrophages, and may have the potential to recognize and bind to pathogen-associated molecular patterns (PAMPs) from Candida albicans, thereby triggering the downstream signals. The genetic polymorphism of TLRs is associated with susceptibility to Candida albicans. The activation of TLRs by PAMPs from Candida albicans can induce the production of proinflammatory cytokines that play key roles in the anti-infection of Candida albicans. However, in order to evade the immune response of host,Candida albicans can also change its bacterial phase. Understanding of the interaction between TLRs and Candida albicans will provide novel evidence to further clarify the mechanisms of anti-fungal immune response.
