Objective: To conduct a scoping review on the types, construction methods and predictive performance of health literacy prediction models based on machine learning methods, so as to provide the reference for the improvement and application of such models. Methods: Publications on health literacy prediction models conducted using machine learning methods were retrieved from CNKI, Wanfang Data, VIP, PubMed and Web of Science from inception to May 1, 2024. The quality of literature was assessed using the Prediction Model Risk of Bias ASsessment Tool. Basic characteristics, modeling methods, data sources, missing value handling, predictors and predictive performance were reviewed. Results: A total of 524 publications were retrieved, and 22 publications between 2007 and 2024 were finally enrolled. Totally 48 health literacy prediction models were involved, and 25 had a high risk of bias (52.08%), with major issues focusing on missing value handling, predictor selection and model evaluation methods. Modeling methods included regression models, tree-based machine learning methods, support vector machines and neural network models. Predictors primarily encompassed factors at four aspects: individual, interpersonal, organizational and society/policy aspects, with age, educational level, economic status, health status and internet use appearing frequently. Internal validation was conducted in 14 publications, and external validation was conducted in 4 publications. Forty-two models reported the areas under the receiver operating characteristic curve, which ranged from 0.52 to 0.983, indicating good discrimination. Conclusion Health literacy prediction models based on machine learning methods perform well, but have deficiencies in risk of bias, data processing and validation.

Abstract Health literate schools (HeLit-Schools) play a significant role in fostering students health literacy. The paper elucidates the background and conceptual connotations of HeLit-Schools, and analyzes how HeLit-Schools effectively integrate and enhance the health literacy of schools in three aspects: philosophy and core drivers, strategy and method implementation, as well as evaluation mechanisms and standard setting. Furthermore, the paper explores the implications of foreign HeLit-Schools research and practice for China under the context of "Healthy China" construction, as well as the key strategies for Chinese schools in the implementation of HeLit-Schools, aiming to provide a new perspective and theoretical support for Chinese schools to practice the "Healthy China initiative" and strengthen school construction from the perspective of health literacy.

Abstract As dietary issues of children and adolescents become increasingly complex, the assessment of food literacy (FL) is increasingly importance. FL involves a comprehensive cognition and practical ability concerning food among children, playing a key role in fostering healthy eating habits and improving health levels. The article explores the definition and connotations of FL, and introduces eight FL assessment tools in terms of theoretical foundations, dimensions, assessment methods, and their reliability and validity. Moreover, it provides a comparative analysis of these tools by examining their dimensional design, evaluation indicators, strengths, and weaknesses, as well as their applicable subjects and scenarios, aiming to offer references for implementing relevant policies and developing more comprehensive and effective FL assessment tools.

Bacterial resistance is a serious problem in use of antibiotics and an urgent global public health challenge. The drug-resistant bacteria and drug-resistant genes carried by migratory birds are not only related to clinical antibiotics, but also the use of pesticides and veterinary drugs as well as the pollution of the surrounding environment of drug factories. However, studies on drug-resistant genes carried in migratory birds have been gradually reported around the world. Migratory birds have the characteristics of large range of movement and long flight distance, which leads to the complexity of bacterial resistance. Under the influence of environment and human activities, drug-resistant genes carried in bacteria are transmitted among species,human beings, domestic animals, environment and wild birds through mobile elements. This study summarizes the current situation of antibiotic resistance bacteria carried by migratory birds,the status of drug-resistant genes in migratory birds and the relationship between the resistance of migratory birds and the environment and human activities. The aim is to better understand the important role of migratory birds as hosts and vectors in the global spread of antibiotic resistance.

Objective:To observe the morphological changes of the sylvian fissure on the transthalamic section of fetal brain at 20-32 weeks, and grade the fetal sylvian fissure development by means of a simple scoring system and explore its clinical feasibility.Methods:From September 2018 to June 2020, 487 normal single fetuses of 20-32 weeks were examined in Shenzhen Maternal and Child Health Hospital Affiliated to Southern Medical University. The sylvian fissure maturation was analyzed on the transthalamic section of fetal brain at 20-32 weeks and was graded from 0 to 5: un-visualized (grade 0), shallow arc (grade 1), obtuse-angled platform (grade 2), right-angled platform (grade 3), acute-angled platform (grade 4), and closed operculum (grade 5). The pregnancy outcomes and gestational age were recorded.Statistical analysis was performed by SPSS 20.0 software using box plot, Mann-Whitney U test, Weighted Kappa coefficient. Results:Left sylvian fissuer grades were obtained in 280 fetuses and right sylvian fissure grades were obtained in 247 fetuses. The fetal sylvian fissure maturation at 20-32 weeks was graded from 0 to 5, which increased with advancing gestation. Grade 0 only appeared in 3 fetuses at 20 weeks, and 99.4% fetuses at 20 weeks had grade ≥1. Grade 1 appeared in 20-22 weeks, grade 2 in 20-25 weeks, grade 3 in 22-26 weeks, grade 4 in 25-32 weeks, and grade 5 in 27-32 weeks. Box-plot and Mann-Whitney U test showed that gestational week distribution of sylvian fissure at all grades was symmetric on both sides ( P>0.05). The Weighted Kappa coefficients were 0.857(95% CI=0.750-0.957) and 0.939 (95% CI=0.859-1.000), respectively, with strong consistency regarding inter- and intra-observer agreements. Conclusions:Fetal sylvian fissure maturation at 20-32 weeks can be evaluated by means of a simple scoring system with symmetrical grading of both sides.

Myopia is a significant global health issue,and its exact causes are still not fully understood,leaving a lack of effective and propaqable treatment options.The prevalence of myopia among children and adolescents in China remains high,posing challenges for prevention and control efforts.According to the"theory of imbalance of essence and tendon",an imbalance in the essential elements and tendons can impede the passage of eye essence and blood,resulting in delayed expansion and contraction of the eye meridians and tendons,leading to blurred vision.Modern research indicates that during the development of myopia,there are notable changes in the microstructure,activation range,and signaling of various brain regions,providing a biological basis for the"brain-eye"mechanism.Moreover,abnormal activity in the brain nucleus contributes to alterations in choroid blood flow and the impairment of eye muscle regulation,thereby accelerating the progression of myopia,this phenomenon represents the manifestation of the brain-eye imbalance.Consequently,strategies for myopia prevention and control should prioritize nourishing kidney essence,replenishing brain marrow,promoting liver and blood health,and softening the meridians.These measures aim to optimize the functioning of the brain and eyes,maintain the flexibility of eye tendons,enhance eye regulation,sustain the strength of eye tendons,and delay the advancement of eye axis growth and myopia.By enriching the scientific understanding of the appropriate application of traditional Chinese medicine techniques to prevent and control myopia through the brain,this research provides valuable insights for future explorations in this field.

Diabetic retinopathy(DR)is one of the major complications of diabetes mellitus, characterized by neurodegeneration and microangiopathy. Currently, the treatment of DR is mainly focused on the management of late complications and has not achieved the desired clinical outcome. Evidence suggests that the PI3K/AKT pathway, as one of the important intracellular signaling pathways during the cell cycle, is involved in the whole process of DR pathogenesis. This article focuses on the structural composition, activation and blocking pathways, conduction pathways, regulatory mechanisms and biological functions of the PI3K/AKT signaling pathway to review its role in DR and to explore the potential of targeting the PI3K/AKT pathway for the treatment of DR.
