ObjectiveTo investigate the incidence and relevant factors of visual acuity abnormalities in preschool children undergoing kindergarten entrance physical examinations in Shannan City, Xizang, in 2022, so as to formulate policies for protecting children’s visual acuity and provide a basis for optimizing the children’s health service system in this region. MethodsA cross sectional study was conducted among the children undergoing kindergarten entrance physical examinations in Shannan City in 2022. A diopter examination was performed for these children, and a questionnaire survey was administered to their caregivers. Additionally, factors affecting children’s visual acuity abnormalities were analyzed using the χ² test and binary logistic regression analysis. ResultsA total of 759 children were included in the analysis, with an incidence rate for visual acuity abnormalities of 11.20%. Univariate analysis showed that statistically significant differences were observed in the incidence rate for visual acuity abnormalities among preschool children in terms of different family monthly income (χ²=17.395, P<0.001), father’s education level (χ²=5.133, P=0.023), postnatal vitamin A and D supplementation (χ²=9.575, P=0.008), and feeding method within the first 6 months after birth (χ²=9.330, P=0.009). Multivariate analysis results indicated that family monthly income <5 000 yuan (OR=2.599, P=0.003), insufficient postnatal vitamin A and D supplementation (OR=1.912, P=0.011), and formula feeding (OR=2.131, P=0.010) were relevant factors for abnormal visual development in children. ConclusionThe incidence of visual acuity abnormalities in preschool children in Shannan City is slightly higher than that previously reported in other regions of Xizang. The occurrence of visual acuity abnormalities in children is related to factors such as family monthly income, postnatal vitamin A and D supplementation, and feeding method within the first 6 months after birth. Future interventions should be strengthened on the promotion and dissemination of knowledge related to eye use, such as improve parental awareness of eye care, promote timely vitamin A and D supplementation and encourage breast feeding for children after birth, more specifically, attentions need to be focused on the visual acuity problems of children from low-income families to safeguard the visual health in preschool children in Shannan City, Xizang.

Objective: To explore the association between dietary behaviors and sleep duration among middle school students in Shanghai, so as to provide reference for interventions targeting insufficient sleep. Methods: From May to June 2021, a stratified cluster random sampling method was employed to select a sample of 10-17yearold middle school students for monitoring their healthrisk behaviors. A total of 5 538 valid questionnaires were collected. The survey included items such as daily sleep duration, weekly consumption of sugary beverages, freshly squeezed fruit juice, fresh fruits, fresh vegetables, fried foods, milk and yogurt, breakfast habits, and frequency of eating outside. Statistical analysis was conducted using Chisquare test, Wilcoxon ranksum test, and multivariable Logistic regression model. Results: About 73.7% of middle school students reported insufficient sleep in Shanghai. There was a positive correlation between the average daily consumption of fresh fruits and breakfast consumption with sleep duration. In other words, a higher frequency of consuming fresh fruits (OR=1.29) and eating breakfast (OR=1.07) were associated with a higher likelihood of sufficient sleep. Conversely, there was a negative correlation between the frequency of consuming desserts (OR=0.78) and fried foods (OR=0.88) and sleep duration (P<0.05). Conclusions Increasing the consumption of fresh fruits and maintaining regular breakfast habits while reducing the intake of fried foods can contribute to achieving sufficient sleep among middle school students. When implementing interventions to improve sleep among middle school students, promoting healthy and balanced diets can be considered as one of the intervention strategies.

Accumulating evidence indicated that microRNAs (miRNA) play an important role in tumor invasion and metastasis by regulating their target genes.However, whether the miRNA-216b-5p(miR-216b-5p ) and their target genes butyrophilin subfamily 3 member A2(BTN3A2) promote glioma invasion and metastasis is unclear.This study aims to study whether miR-216b-5p promoted migration and invasion in glioma cells by negatively regulating BTN3A2.The differential expression analysis of GSE15824 and GSE4290 was analyzed by GEO2R.We found that only BTN3A2 is up-regulated in both GSE15824 and GSE4290 (P<0.05).The gene set enrichment analysis (GSEA) analysis indicated BTN3A2 was related to many cancer-related pathways (P<0.05).The results of survival curves showed that the overall survival of patients with high expression of BTN3A2 decreased significantly (P <0.001).The expression of BTN3A2 was increased with the increase of WHO grade (P<0.05), while the expression of BTN3A2 was increased in 1p/19q uncombined deletion and IDH mutant patients (P<0.001).Western blotting results showed that BTN3A2 was up-regulated in seven glioma tissues and glioma cell lines U87, U251 and LN-229 and downregulated in the miR-216b-5p mimics group; Transwell results showed that transfection with BTN3A2 silencing plasmids(si-BTN3A2) or miR-216b-5p mimics plasmids could inhibit the ability of migration and invasion in LN-229 cells in vitro (P<0.05).The online websites predicted miR-216b-5p as a potential target gene of BTN3A2.The survival curve results show that compared with patients with low expression of miR-216b-5p , the survival rate of patients with high expression was significantly increased (P=0.025).The relative expression of miR-216b-5p was decreased in U87, U251 and LN229 cells was detected by real time quantitative PCR (P<0.05).The results of dual luciferase assay showed that BTN3A2 could bind to miR-216b-5p (P<0.05).Transwell experiment results showed that overexpression of miR-216b-5p can inhibit the migration and invasion ability of LN229 cells (P<0.05).In summary, miR-216b-5p promotes the migration and invasion by targeting BTN3A2 of LN-229 glioma cells.

OBJECTIVE: To investigate the epidemiological characteristics of mumps in mainland China from 2004 to 2018, and to provide data for the key population for prevention and control of mumps. METHODS: The epidemiological characteristics of mumps were analyzed with reference to the data of the cases of mumps reported in the National Scientific Data Sharing Platform for Population and Health and Disease Prevention and Control Bureau of National Health Commission of the People's Republic of China. Descriptive epidemiology was used to analyze the epidemiological characteristics of mumps. RESULTS: A total of 4 272 368 cases of mumps were reported in China during 2004-2018, with an average annual reported incidence rate of 21.44/100 000. A single dose of mumps-containing vaccine was added to the national Expanded Program of Immunization in 2008, but the annual incidence rate ranged from 12.84/100 000 to 35.59/100 000. The second dose of measles, mumps and rubella combined attenuated live vaccine was included in the routine immunization in Beijing, Tianjin and Shanghai, and then the average incidence rate of mumps reported in these three regions dropped to about 10/100 000. From 2004 to 2016, the population aged 3-14 years accounted for 81.16% of all patients with mumps. The children aged 6 years had the highest incidence rate of mumps during 2004-2013. CONCLUSIONS A single dose of mumps-containing vaccine has no obvious effect on the incidence rate of mumps. Children aged 6 years have the highest incidence rate of mumps. A booster dose of mumps-containing vaccine should be given to preschool children.

OBJECTIVE: This study aimed to investigate the oral health service needs and dental treatment among 3-year-old to 5-year-old preschool children in Jiangxi province and provide data to support the development of relevant oral health policies, enhance the oral health service utilization and visit rate, and optimize oral manpower and service resources. METHODS: A total of 2 880 preschool children were selected via stratified cluster sampling. Dental examination methods and criteria according to the fourth national oral health epidemiological survey were adopted. Excel 2007 and SPSS 19.0 softwares were used for statistics analysis. Chi-square test and logistic regression analysis were performed. RESULTS: The caries prevalence was 49.13% (1 415/2 880) among the 2 880 cases of 3-
year-old to 5-year-old preschool children in Jiangxi province, approximately 53.37% (1 537/2 880) of which possessed oral health service needs. The parents of younger children assessed the oral situation better in older age than in their younger years (P<0.05), which was better in urban children than in rural children (P<0.05). The visiting rate of all the respondents was 12.33% (355/2 880), while the visiting rate of children with oral diseases was 17.31% (266/1 537). The top three reasons why patients did not visit the dentist were as follows: children's teeth have no problem, the teeth damage in teeth was considerably minimal, and primary teeth would be replaced without the need for treatment. The influencing factors included lower visiting rate in females than in males (OR=0.499, 95%CI: 0.411-0.606) and lower visiting rates in rural areas than in urban areas (OR=0.428, 95%CI: 0.353-0.519). Subjects with poor oral health and high oral knowledge scores possessed high dental service visit rates. CONCLUSIONS The prevalence of caries in 3-year-old to 5-year-old preschool children in Jiangxi province is at a lower level than that in the national level. The proportion of the population actively seeking medical services is low, and their main purpose of treatment is to treat rather than prevention. Oral health education should be strengthened, and it should be incorporated to the contents of the kindergarten teacher training program to improve residents' awareness regarding children's oral health.
