1.Expert recommendations on vision friendly built environments for myopia prevention and control in children and adolescents
Chinese Journal of School Health 2026;47(1):1-5
Abstract
The prevention and control of myopia in Chinese children and adolescents has become a major public health issue. While maintaining increased outdoor activity as a cornerstone intervention, there is an urgent need to explore new complementary approaches that can be effectively implemented in both indoor and outdoor settings. In recent years, environmental spatial frequency has gained increasing attention as one of the key environmental factors influencing the development and progression of myopia. Both animal studies and human research have confirmed that indoor environments lacking mid to high spatial frequency components, often characterized as "visually impoverished", can promote axial elongation and myopia through mechanisms such as disruption of retinal neural signaling, impaired accommodative function, and altered expression of related molecules. Based on the scientific consensus, it is recommended that "enriching of environmental spatial frequency" should be integrated into the myopia prevention and control framework. Following the principles of schoolled organization, family cooperation, community involvement, and student participation, specific measures are put forward in three areas:optimizing school visual settings, improving home spatial environments, and promoting healthy visual behavior. The aim is to create "visually friendly" indoor environments as an important supplement to outdoor activity, thereby providing a novel perspective and strategy for comprehensively advancing myopia prevention and control among children and adolescents.

3.Indoor environment management and CO 2 volume concentration of primary and secondary school classrooms in winter across three provinces and municipalities of China
Chinese Journal of School Health 2026;47(2):163-167
Objective:
To evaluate the classroom environmental management and CO 2 volume concentration in primary and secondary schools from Liaoning, Tianjin, and Shanghai, thereby providing a scientific basis for developing targeted strategies to improve classroom air quality.
Methods:
From December 16 to 26, 2024, by using stratified random cluster sampling method, the questionnaire survey was conducted in 72 primary and secondary schools (24 each of primary, junior high, and regular high schools) across Liaoning, Tianjin and Shanghai. Information on heating, ventilation and other classroom environmental management was collected. Additionally, 108 classrooms were selected for on site microclimate measurements, including temperature, humidity, wind speed and CO 2 volume concentration. Univariate analysis and multiple linear regression models were employed to explore related factors of classroom CO 2 volume concentration.
Results:
Among the three provinces/municipalities, 20.8% of schools regularly monitored the microclimate. The overall compliance rate for classroom CO 2 volume concentration was 17.6%. Multiple linear regression analysis showed that CO 2 volume concentration in regular and junior high school classrooms were higher than in primary school classrooms ( β=0.067, 0.046, 95%CI =0.036-0.099, 0.013-0.080); classrooms ventilated regularly in the morning and afternoon had higher CO 2 volume concentration than those ventilated during every break between classes ( β=0.043, 95%CI = 0.007- 0.080); both temperature ( β=0.010, 95%CI =0.004-0.016) and humidity ( β=0.003, 95%CI =0.002-0.004) were positively correlated with CO 2 volume concentration (all P <0.05).
Conclusions
Excessive CO 2 volume concentration in primary and secondary school classrooms is a prominent issue, and ventilation frequency is a key intervenable factor for controlling CO 2 levels. It is recommended to promote ventilation during every break between classes as a core management measure and to emphasize air quality supervision in regular high school classrooms.

Intravitreal anti-vascular endothelial growth factor(anti-VEGF)therapy has been widely used, but the variability in its therapeutic efficacy limits individualized treatment. In recent years, the application of artificial intelligence(AI)has opened up new avenues for personalized treatment response prediction, and its core branches include machine learning(ML)and deep learning(DL). This review systematically retrieved and analyzed 41 relevant studies published up to April 2025. Comprehensive analysis reveals that AI predictive models are evolving from forecasting single endpoints(such as visual acuity or central retinal thickness)to integrating multi-dimensional endpoints(encompassing anatomical, functional, and treatment demand parameters)and generating predictive imaging outputs. In terms of technical approaches, DL models(28 studies, accounting for 68.3%)dominate this field due to their robust image interpretation capabilities, while ML models(10 studies, 24.4%)retain significant value in the analysis of structured clinical data. Cross-disease comparisons indicate that research efforts are most concentrated on age-related macular degeneration(ARMD)and diabetic macular edema(DME), with shared conceptual frameworks for model construction, yet distinct anatomical and functional indicators are prioritized for each disease. Currently, the field confronts several key challenges, including insufficient prospective clinical validation, limited model interpretability(the “black box problem”), and a scarcity of high-quality multi-center datasets. Moving forward, it is imperative to advance real-world validation and develop explainable AI techniques to expedite the clinical translation of these predictive models.

In this work, starting from 4-hydroxycoumarin, three series of 22 coumarin derivatives, among which 8 have not been reported in the literature, were synthesized and their in vitro anti-inflammatory activities and mechanisms of action were preliminarily investigated using mouse macrophage model. The results showed that most of the derivatives could significantly inhibit the production of pro-inflammatory factor NO, with compounds 2e, 2f, 2g, 2h, 2i, 2j, 4e, and 4f showing better anti-inflammatory activity than the positive control drug dexamethasone. Further experiments showed that compounds 2h and 4f significantly inhibited the production of pro-inflammatory factors IL-6, TNF-α and IL-1β in RAW264.7 macrophages, and could, therefore, be used as lead compounds for further studies.

ObjectiveTo investigate the efficacy and safety of the direct-acting antiviral agents coblopasvir hydrochloride/sofosbuvir (CLP/SOF) regimen used alone or in combination with ribavirin (RBV) in the treatment of patients with genotype 3 hepatitis C virus (HCV) infection in terms of virologic response rate, liver function recovery, improvement in liver stiffness measurement (LSM), and adverse drug reactions, and to provide a reference for clinical medication. MethodsA total of 98 patients with genotype 3 HCV infection who attended The Third People’s Hospital of Kunming from January 2022 to December 2023 were enrolled, and according to the treatment method, the patients were divided into CLP/SOF+RBV treatment group with 55 patients and CLP/SOF treatment group with 43 patients. The patients were observed in terms of rapid virologic response at week 4 (RVR4), sustained virologic response (SVR), previous treatment experience, underlying diseases, laboratory and imaging indicators, and adverse reactions during treatment. The course of treatment was 12 weeks, and the patients were followed up for 12 weeks after drug withdrawal. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the Friedman test was used for comparison within each group at different time points, and the Bonferroni method was used for further comparison and correction of P value; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The univariate and multivariate Logistic regression analyses were used to investigate the influencing factors for SVR12. ResultsBefore treatment, there were significant differences between the CLP/SOF+RBV treatment group and the CLP/SOF treatment group in terms of LSM, total bilirubin (TBil), gamma-glutamyl transpeptidase (GGT), HCV genotype, and the presence or absence of liver cirrhosis and compensation (all P<0.05). The 98 patients with genotype 3 HCV infection had an RVR4 rate of 81.6% and an SVR12 rate of 93.9%. The patients with genotype 3a HCV infection had an RVR4 rate of 84.44% and an SVR12 rate of 97.78%, while the patients with genotype 3b HCV infection had an RVR4 rate of 79.25% and an SVR12 rate of 90.57%. There were significant differences in RVR4 and SVR12 rates between the patients without hepatocellular carcinoma and those with hepatocellular carcinoma, there was a significant difference in RVR4 rate between the patients without HIV infection and those with HIV infection, and there was a significant difference in SVR12 rate between the previously untreated patients and the treatment-experienced patients (all P<0.05). The univariate Logistic regression analysis showed that treatment history, hypertension, hepatocellular carcinoma, ascites, albumin (Alb), and platelet count were influencing factors for SVR12 (all P<0.05), and the multivariate Logistic regression analysis showed that hepatocellular carcinoma (odds ratio=0.034, 95% confidence interval: 0.002 — 0.666, P=0.026) was an independent influencing factor for SVR12. After treatment with CLP/SOF combined with RBV or CLP/SOF alone, the patients with genotype 3 HCV infection showed gradual reductions in the liver function parameters of TBil, GGT, and alanine aminotransferase (all P<0.05) and a gradual increase in the level of Alb (P<0.05). As for renal function, there were no significant changes in blood urea nitrogen and creatinine after treatment (P>0.05). For the patients with or without liver cirrhosis, there was a significant reduction in LSM from baseline after treatment for 12 weeks (P<0.05). Among the 98 patients with genotype 3 HCV infection, 9 tested positive for HCV-RNA at 12 weeks after treatment, 2 showed no response during treatment, 4 showed virologic breakthrough, and 3 experienced recurrence. The overall incidence rate of adverse events during treatment was 17.35% for all patients. ConclusionCLP/SOF alone or in combination with RBV has a relatively high SVR rate in the treatment of genotype 3 HCV infection, with good tolerability and safety in patients during treatment, and therefore, it holds promise for clinical application.

ObjectiveTo reveal the changing pattern of fungal communities and isoflavone content during the fermentation of Sojae Semen Praeparatum. MethodsInternal transcribed spacer (ITS) amplicon sequencing was used to analyze the changes in fungal communities during the fermentation. High-performance liquid chromatography (HPLC) was employed to determine the composition and content of isoflavones. Spearman correlation analysis was conducted to identify fungal communities positively correlated with isoflavone content. ResultsDuring the fermentation of Sojae Semen Praeparatum, the abundance of Penicillium continued to increase and became the dominant genus from the "yellow cladding" to the early "secondary fermentation" stage (9 days). However, in the mid-to-late "secondary fermentation" stage (12-21 days), the abundance of Penicillium decreased, while the abundance of Barnettozyma increased rapidly, becoming the dominant genus during the later stages (18-21 days). Alpha diversity analyses showed that fungal diversity was higher in the "secondary fermentation" stage than in the "yellow cladding" stage. Beta diversity analyses showed greater variability in fungal communities during the "yellow cladding" stage, with relatively stable fungal communities during the "secondary fermentation" stage. The aglycone isoflavone content exhibited a gradual increase, rising from 5.56% at the start of fermentation to 96.84% by the end. In contrast, the glucoside isoflavone content experienced a corresponding decline, decreasing from 94.44% to 3.16%. Spearman analysis showed that Penicillium, Barnettozyma, and Ilyonectria were positively correlated with the contents of daidzein, glycitein, and genistein, and promoted the conversion of isoflavones from glucoside to aglycone forms. ConclusionThe fungal communities of Penicillium, Barnettozyma, and Ilyonectria promote the conversion of isoflavones from glucoside to aglycone forms during the fermentation of Sojae Semen Praeparatum. The findings provide an important reference for improving the scalability and quality of Sojae Semen Praeparatu fermentation.

Chinese Journal of School Health 2025;46(8):1190-1193
Objective:
To understand the home reading-writing levels among children and adolescents in Shanghai after school, and to explore its association with screening myopia, so as to provide a scientific basis for the prevention and control of myopia.
Methods:
From April to December 2024, 641 primary and middle school students were recruited from 2 urban schools and 1 rural school in Shanghai to participate in the survey. An illuminance meter was used to measure the illuminance of home reading-writing activities after school. Screening myopia was determined through visual acuity examination and refractive detection under non ciliary muscle paralysis conditions among children and adolescents. A binary Logistic regression model was used to analyze the association between home reading-writing illuminance and screening myopia.
Results:
The detection rate of screening myopia among children and adolescents in Shanghai was 59.9%. The median home reading-writing illuminance after school was 340.9(112.2, 753.5) lx, and 45.4% was found of less than 300 lx. The family illuminance in the primary school stage [432.0 (136.9, 837.0) lx] was higher than that in the junior high school stage [113.1(53.7, 375.1) lx], and main urban area group [503.9 (212.6, 969.5) lx] was higher than that in the rural group [141.6 (53.7, 416.9) lx], the differences were statistically significant (Z=-7.56, -9.95,both P<0.05). The results of Logistic regression analysis showed that compared with the family illuminance of 150-500 lx, children and adolescents with family illuminance<150 and >500 lx had increased risks of screening myopia detection[OR(95%CI)=1.56(1.01-2.42), 1.74(1.15-2.62),both P<0.05].
Conclusions
The home reading-writing illuminance after school is suboptimal. Both excessively low and high home reading-writing illuminance levels are associated with screen-detected myopia. It is necessary for children and adolescents to improve lighting conditions during evening reading-writing activities, and strengthen health education according to different regions and school stages.
9.Current status of indoor light at night exposure during sleep among children and adolescents in Shanghai
Chinese Journal of School Health 2025;46(9):1262-1265
Objective:
To understand the indoor light at night (LAN) exposure intensity during sleep among children and adolescents in Shanghai, so as to provide a basis for exploring potential health risks and formulating effective interventions.
Methods:
From April to December in 2024, a total of 628 students in grades 4-7 were recruited from three schools in Shanghai. A portable illuminance meter was used to measure LAN for one week, and participants recorded their sleep time. The Kruskal-Wallis H- test was used for comparison between groups, and the error bar chart was used to show the trend and variation range of average LAN exposure intensity in different sleep periods.
Results:
The indoor LAN exposure intensity of children and adolescents in Shanghai was [2.4(0.8, 5.9)lx] during sleep, and 28.8% of children and adolescents were exposed to indoor LAN≥5 lx. There was no significant differences in indoor LAN exposure intensity between boys [2.4(1.0, 5.9)lx] and girls [2.3(0.7, 5.9)lx] ( Z=-0.86, P > 0.05 ). The indoor LAN exposure intensity of primary school students [2.9(1.1, 6.6)lx] was higher than that of junior high school students [1.0(0.3, 3.1)lx] ( Z =-5.87), and indoor LAN exposure intensity of students in the main urban area [3.2(1.1, 7.8)lx] was higher than that of rural students [1.6(0.5, 4.3)lx] ( Z =-5.23)(both P <0.05). The indoor LAN exposure intensity showed an overall decreasing trend during sleep of children and adolescents ( tau=-0.81, P =0.02), with a slight increase before waking up.
Conclusions
Indoor LAN exposure intensity among children and adolescents in Shanghai is generally high, especially among primary school students and students living in the main urban area. Health policy and education should be strengthened to reduce the impact of LAN on children and adolescent health.

OBJECTIVE To evaluate the efficacy and safety of immune checkpoint inhibitors combined with neoadjuvant chemotherapy and adjuvant chemotherapy in the treatment of early-stage triple-negative breast cancer (TNBC). METHODS A systematic search was conducted in PubMed, Embase, Cochrane Library, CNKI, and Wanfang Data to collect randomized controlled trials (RCT) on the use of immune checkpoint inhibitors combined with neoadjuvant chemotherapy and adjuvant chemotherapy (experimental group) versus neoadjuvant chemotherapy and adjuvant chemotherapy (control group) in the treatment of TNBC. After literature screening, data extraction and literature quality evaluation, meta-analysis was performed using Stata 17.0. RESULTS A total of 5 RCT involving 1 498 patients were included. The meta-analysis results showed that the pathological complete response rate (pCR) [RR=1.34, 95%CI (1.09, 1.63), P=0.03], pCR in patients with positive programmed death-1 (PD-1) and its ligand (PD-L1) [RR=1.33, 95%CI (1.16, 1.51), P=0.01], pCR in patients with positive lymph nodes [RR= 1.56, 95%CI (1.27, 1.93), P=0.01], the incidence of grade 3-4 adverse events (AEs) [RR=1.07, 95%CI (1.01, 1.14), P= 0.04], the incidence of serious AEs [RR=1.57, 95%CI (1.31, 1.87), P=0.03], and the incidence of treatment discontinuation due to AEs [RR=1.45, 95%CI (1.19, 1.76), P=0.01] were significantly higher in the experimental group than control group. There were no statistically significant difference in pCR in patients with negative PD-1/PD-L1[RR= E-mail:biejun23@126.com 1.26, 95%CI (0.98, 1.62), P=0.08] and pCR in patients with negative lymph nodes [RR=1.14, 95%CI (0.97, 1.33), P=0.17] between the two groups. CONCLUSIONS Immune checkpoint inhibitors combined with neoadjuvant chemotherapy and adjuvant chemotherapy demonstrates significant efficacy in early-stage TNBC patients, with more pronounced benefits observed in those who are PD-1/PD-L1 positive and lymph node- positive. However, the incidence of AEs is relatively high.
