Abstract To clarify the service targets, service contents, and safeguard mechanisms of the basic public service program for student vision health management, the study grounded in the current status of child and adolescent myopia prevention and control in China and integrated with the practical experience and innovative practices of Wuhan National Demonstration Area for Student Vision Health Management, takes education as the main thread and schools as the base, consolidating resources from multiple stakeholders including education administrative departments, schools, families, and professional technical service institutions. Centering on four core components—vision health education, monitoring and record keeping, risk prevention and control, and dynamic management, the study constructs a multi tiered basic public service system for vision health management of primary and secondary school students. It further proposes the use of an intelligent management platform and a "three tier color coded early warning" mechanism (red, yellow, blue) to prevent and control student myopia at the source, providing schools with replicable and operable implementation pathways to enhance the level of student vision health management.

Abstract Smartphone addiction adversely effects the physical and mental health of adolescents. Individual psychological factors serve as direct contributors to smartphone addiction in adolescents, and smartphone addiction also affects the individual mental well being. Research suggests that psychological factors such as anxiety and depression, social anxiety and loneliness, self control, sensation seeking, and mindfulness interact with adolescent smartphone addiction. The article reviews the research progress on the relationship between these individual psychological factors and adolescent smartphone addition, so as to provide a reference for understanding and addressing adolescent smartphone addiction from an individual psychological perspective.

ObjectiveTo observe the effect of gene mutation on the effectiveness of arsenic-containing Chinese herbal compound formulas in the treatment of myelodysplastic syndromes （MDS） of different traditional Chinese medicine （TCM） patterns， so as to provide the basis for the clinical application. MethodsClinical data of 442 MDS patients who were treated with arsenic-containing herbal compound formulas were retrospectively collected， including the baseline demographic and clinical characteristics of the patients. Based on the TCM four examinations， the patients were divided into the spleen-kidney deficiency group as well as the qi-yin deficiency group， and according to the results of the next-generation sequencing （NGS） test， they were divided into the group with and without gene mutation respectively. The influence of gene mutation on the clinical effectiveness of patients with different TCM patterns was analyzed， the baseline demographic and clinical characteristics of the patients with different outcomes of the two TCM patterns were compared， and multivariate Logistic regression analysis was conducted on the influencing factors of the effective rate of MDS patients with gene mutation. ResultsA total of 190 cases were included in the spleen-kidney deficiency group （119 cases with gene mutation） and 43 cases in the qi-yin deficiency group （23 cases with gene mutation）. No statistically significant differences were noted in effectiveness assessment， total effective rate， and total response rate between the spleen-kidney deficiency group and the qi-yin deficiency group （P＞0.05）. In the spleen-kidney deficiency group， the total effective rate of MDS with gene mutation was 65.55% （78/119）， which was lower than 80.28% （57/71） of MDS without gene mutation， with statistical significance （P = 0.033）， while no statistical differences in effectiveness assessment and total response rate were noted （P＞0.05）. In the qi-yin deficiency group， no statistical differences were observed in effectiveness assessment， total effective rate， and total response rate of the patients in with or without gene mutation （P＞0.05）. In the spleen-kidney deficiency group with gene mutation， the rate of complex karyotype （P = 0.031） and the mutation rate of CBL gene （P = 0.032） in the ineffective population were higher than those in the effective population， while the mutation rate of DDX41 gene in the effective population was higher than that in the ineffective population （P = 0.033）. No statistically significant differences were found in other gene mutations， age， gender distribution， number of gene mutations， bone marrow hyperplasia degree， blast cell range， reticular fiber tissue proliferation or not， and prognosis of chromosomal abnormalities between the effective and ineffective populations （P＞0.05）. In the qi-yin deficiency group with gene mutation， no statistically significant differences were found in various items between populations with different outcomes （P＞0.05）. Multivariate Logistic regression analysis showed that complex karyotype， CBL mutation， and DDX41 mutation were independently associated with the effective rate of MDS with spleen-kidney deficiency and gene mutation （P＜0.05）. DDX41 mutation was an independent protective factor in the spleen-kidney deficiency group （OR＞1）， while complex karyotype and CBL mutation were independent risk factors （OR＜1）. ConclusionThe arsenic-containing TCM compound formulas exhibited better effectiveness in MDS with spleen-kidney deficiency pattern without mutation； and in MDS with spleen-kidney deficiency pattern without complex karyotypes， CBL mutation， and with DDX41 mutations. Furthermore， DDX41 mutation was an independent protective factor in the spleen-kidney deficiency group， while complex karyotype and CBL mutation were independent risk factors. In MDS with qi-yin deficiency pattern， gene mutation-related factors showed no significant impact on the effectiveness of arsenic-containing TCM compound formulas.

Objective:To analyze the clinical features and genetic sequencing results of a patient with Kallmann syndrome(KS) carrying digenic mutations who initially presented with osteoporosis, and to enhance awareness of this disease phenotype.Methods:Clinical data were collected, and peripheral blood DNA was extracted for whole-exome sequencing. Relevant literature was reviewed to summarize phenotypes associated with digenic/oligogenic variants involving CHD7.Results:The patient exhibited back pain, delayed development of secondary sexual characteristics, and hyposmia. Laboratory tests revealed reduced sex hormones and gonadotropin levels, while pituitary imaging was unremarkable. Bone mineral density imaging confirmed osteoporosis, and thoracolumbar X-rays showed multiple vertebral compression fractures. Genetic analysis identified a heterozygous splice-site mutation in CHD7(c.2698-1G>T) and a heterozygous missense mutation in WDR11(c.439G>A: p.D147N). According to ACMG criteria, the CHD7 mutation was classified as pathogenic, while the WDR11 variant was defined as a variant of uncertain significance(VUS). Literature review indicated that 40% of KS patients with digenic/oligogenic variants involving CHD7 presented with hearing or ocular abnormalities.Conclusion:This study reports a novel CHD7 mutation and a previously undescribed digenic combination of CHD7 and WDR11 variants in a KS patient. CHD7 variants may be implicated in auditory or ocular involvement in KS cases with digenic/oligogenic inheritances. KS patients may also manifest skeletal abnormalities in addition to hypogonadotropic hypogonadism. Tailored management of sex hormones and osteoporosis therapies across life stages is essential for optimizing bone health in KS.

[Objective]Based on the holistic view of"correspondence between nature and humans"in Huangdi Neijing,which is central to traditional Chinese time medicine theory,to explore a new diagnostic and therapeutic approach to insomnia from the perspective of"time".[Methods]By grounding in ancient and modern literature,this study elucidates the connotations of traditional Chinese time medicine and systematically reviews the temporal rhythms and derived theories related to insomnia in Huangdi Neijing,summarizing the approach to treating insomnia through time medicine.[Results]The disruption of the wake-sleep rhythm is a primary pathological mechanism of insomnia.The circadian rhythm,the four seasons rhythm,the exceeding the age rhythm and the meridians rhythm discussed in Huangdi Neijing are closely related to insomnia.They could be encapsulated into four major theories:the waxing and waning of Yin and Yang,the viscera and bowels managing time,the five movements and six climates,and the midnight-midday ebb flow theory.This study advocates a four-level strategy for insomnia,closely aligned with time medicine theory and the pathogenesis of insomnia,namely"regulating Yin and Yang""adapting to the four seasons""responding to annual Qi"and"reinforcement and elimination of Nazhi".[Conclusion]The time medicine concept in Huangdi Neijing has objectively effects in the prevention and treatment of insomnia,providing a new breakthrough and integration point for clinical diagnosis and treatment of insomnia.In clinical diagnosis and treatment of insomnia,the consideration of time rhythms should be fully integrated to achieve optimal therapeutic outcomes.

Objective:To explore the diagnostic value of the macrophage activation syndrome/systemic juvenile idiopathic arthritis（MS）score in macrophage activation syndrome（MAS）associated with systemic juvenile idiopathic arthritis（sJIA），and to provide a reference for clinical work.Methods:This study was a retrospective case-control analysis，conducted on the patients initially diagnosed as sJIA-associated with MAS and admitted into the Department of Rheumatology and Immunology of Children's Hospital Affiliated to Xi 'an Jiaotong University from July 1st，2016 to June 30th，2023. All of the patients met the diagnostic criteria for patients with MAS associated with sJIA according to the 2016 European Alliance of Associations for Rheumatology（EULAR）/American College of Rheumatology（ACR）/Pediatric Rheumatology International Trials Organization（PRINTO）standards. The basic information at baseline，clinical manifestations，and auxiliary examination results were collected. The MS score was applied to re-evaluate the children diagnosed as sJIA-associated with MAS. When the MS score ≥-2.1，the possibility of sJIA with MAS was high. Thirty cases of sJIA without MAS were randomly selected as the control group.Results:There were 28 cases in the MAS group，including 13 males（46.43%）and 15 females（53.57%），with an average age of（7.51±4.01）years. Compared with the control group，the MAS group were significantly more likely to have high fever（ χ2=8.539， P=0.003），hepatomegaly（ χ2=11.621， P<0.001），splenomegaly（ χ2=11.710， P<0.001）and neurological involvement（ χ2=27.619， P<0.001），with the differences being statistically significant. Meanwhile，there were statistically significant differences between the two groups in terms of white blood cell count（ Z=-4.001， P<0.001），neutrophil count（ Z=-3.659， P<0.001），platelet count（ Z=-4.687， P<0.001），albumin level（ Z=-4.018， P<0.001），alanine aminotransferase（ Z=-3.846， P<0.001），aspartate aminotransferase（ Z=-5.932， P<0.001），lactate dehydrogenase（ Z=-6.150， P<0.001），triglycerides（ Z=-5.874， P<0.001），fibrinogen（ Z=-5.808， P<0.001），ferritin（ Z=-5.280， P<0.001），erythrocyte sedimentation rate（ Z=-3.971， P<0.001），ferritin/erythrocyte sedimentation rate（ Z=-5.433， P<0.001），reduction of two-line cells in blood（ χ2=11.408， P<0.001）and the presence of hemophagocytosis in bone marrow smears（ χ2=28.260， P<0.001）. Moreover，there was a statistically significant difference in MS scores between the two groups（ Z=-6.148， P<0.001），with higher MS scores in the MAS group. Nevertheless，this study showed the median MS scores of both groups ≥-2.1. Conclusion:The MS score was significant to a certain degree as reference for the diagnosis of MAS，and this study showed that the MS score in the MAS group was significantly higher than the control group. However，the median MS scores in both groups were no less than -2.1. This might be related to the influence of factors during the assessment，which made it necessary to optimize the cutoff values of the MS score. Therefore，prospective studies should be carried out on the role of MS score in early identification of MAS.

Peganum harmala L. (P. harmala) is a significant economic and medicinal plant. The seeds of P. harmala have been extensively utilized in traditional Chinese medicine, Uighur medicine, and Mongolian medicine, as documented in the Drug Standard of the Ministry of Health of China. Twelve novel tryptamine-derived alkaloids (1-12) and eight known compounds (13-20) were isolated from P. harmala seeds. Compounds 1 and 2 represent the first reported instances of tryptamine-derived heteromers, comprising tryptamine and aniline fragments with previously undocumented C-3-N-1' linkage and C-3-C-4' connection, respectively. Compounds 3-5 were identified as indole-quinazoline heteromers, exhibiting a novel C-3 and NH-1' linkage between indole and quinazoline-derived fragments. Compound 6 demonstrates the dimerization pattern of C-C linked tryptamine-quinazoline dimer. Compound 8 represents a tryptamine-derived heterodimer with a distinctive carbon skeleton, featuring an unusual spiro-tricyclic ring (7) and conventional bicyclic tryptamine. Compounds 9-11 constitute novel 6/5/5/5 spiro-tetracyclic tryptamine-derived alkaloids presenting a unique ring system of tryptamine-spiro-pyrrolizine. Compounds 1-3 and 6-11 were identified as racemates. Compounds 2, 7, 9, 10, and 12 were confirmed via X-ray crystallographic analysis. All isolated compounds (1-20) exhibited varying degrees of antiviral efficacy against respiratory syncytial virus (RSV). Notably, the anti-RSV activity of compound 12 (IC₅₀ 5.01 ± 0.14 μmol·L^-1) surpassed that of the positive control (ribavirin, IC₅₀ 6.23 ± 0.95 μmol·L^-1), as validated through plaque reduction and immunofluorescence assays. The identification of anti-RSV compounds from P. harmala seeds may enhance the development and application of this plant in antiviral therapeutic products.

Objective To investigate the correlation between physical activity duration,sleep quality,weight control,and PRO(patient-reported outcomes)in individuals with hypertension,providing effective information for enhancing patient-reported outcomes in this population.Methods A total of 625 hypertensive patients were randomly selected from four counties in Yunnan Province from April to June 2020 to participate in a field survey.The questionnaire included patients'basic information,lifestyle,health status and the PRO Scale for Hypertension-PROISCD-HY(V1.0).Statistical analyses including t-tests,one-way ANOVA,and multivariate linear regression were conducted to investigate the relationships between physical activity duration,sleep quality,weight control,and PRO,with the Bootstrap method used to examine potential mediating effects.Results After adjusting for potential covariates,the multiple linear regression model indicated a significant association between a physical activity duration of≥2 hours with PRO[B=6.551,95%CI(2.611,10.491)].Stratified analysis showed that this association was only present among males,females,and younger adults,but not in older adults.Additionally,a positive correlation was found between good sleep quality and PRO[B=1.870,95%CI(0.449,3.291)],with this association being consistent across all populations after stratification.Patients who managed their condition through exercise and diet had higher PRO scores[B=1.904,95%CI(0.383,3.424)],while those controlling weight through diet and other methods exhibited a decrease in PRO scores[B=-4.873,95%CI(-7.860,-1.887);B=-7.105,95%CI(-12.211,-1.999)],with variations among different groups.The bootstrap method revealed that physical activity duration had both direct and indirect effects on PRO,with sleep quality acting as a partial mediator between physical activity duration and PRO.Conclusion A Physical activity duration of at least 2 hours,good sleep quality,and weight control have been shown to improve PRO in individuals with hypertension.

Objective:To evaluate the efficacy of a low-fluence Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser combined with light-emitting diode (LED) phototherapy in the treatment of melasma.Methods:A total of 46 female patients with melasma, with age ranging from 30 to 58 (41.4±5.8) years, were retrospectively collected from August 2022 to February 2024 at the Department of Plastic Surgery, the First Affiliated Hospital of Army Medical University. The patients were divided into two groups according to the treatment method. The experimental group received low-fluence Q-switched Nd:YAG laser treatment combined with LED phototherapy ( n=23), whereas the control group received low-fluence Q-switched Nd:YAG laser treatment alone ( n=23). The treatment interval for both groups was 4 weeks, and a total of four treatments were conducted. Treatment efficacy was evaluated at the 12-week follow-up after completion of the entire treatment course. Pre-treatment and post-treatment melasma area and severity index (MASI) scores were compared between the two groups. The pain visual analog scale (VAS) score was obtained immediately after each treatment. The occurrence of adverse reactions after treatment, including blisters, persistent erythema, hyperpigmentation, hypopigmentation, and scarring, was recorded in both groups. Results:The efficacy rates in the experimental and control groups were 87% (20/23) and 82.61% (19/23), respectively, with no statistically significant difference between them ( P=1.000). The pre-treatment MASI scores of the experimental and control groups were (24.60±8.69) and (21.48±9.01) scores, respectively, with no statistically significant difference between them ( P=0.239). The post-treatment MASI scores of the experimental group was (7.70±4.36) scores, which was significantly lower than that of the control group [(16.34±7.29) scores, P<0.001). In both groups, the post-treatment MASI scores were significantly lower than the pre-treatment MASI scores (all P<0.001). Both groups experienced mild pain during the treatment. The VAS scores for pain during laser treatment in the experimental and control groups were (1.78±0.90) and (1.61±0.89) scores, respectively, with no statistically significant differences between them ( P=0.514). In the experimental group, the VAS score for pain was zero during LED phototherapy, indicating no increase in pain. No adverse reactions such as blisters, persistent erythema, hyperpigmentation, hypopigmentation, or scarring were observed in either group. Conclusion:Low-fluence Q-switched Nd:YAG laser combined with LED phototherapy can effectively improve the efficacy of melasma treatment, without increasing pain or any other serious adverse effects during or after therapy.

Severe open tibiofibular fractures account for approximately 28.1% of all open fractures. Among them, Gustilo-Anderson type IIIB/C fractures present significant clinical challenges due to associated bone and soft tissue defects, high infection rates, and risk of amputation. Inadequate preoperative assessment may lead to suboptimal emergency surgical planning or intraoperative complications. Historically, external fixation was often preferred, but this approach has been associated with limitations such as restricted joint mobility, delayed bone union, joint stiffness, and disuse osteoporosis, resulting in poor functional recovery. With advancements of debridement techniques, standardization of antibiotic use, and popularization of early soft tissue coverage, early internal fixation has gained broader acceptance. Nevertheless, controversies persist regarding the choice of fixation method, timing of definitive fixation, use of reamed versus unreamed intramedullary nailing, and necessity of fibular fixation. To standardize the diagnosis and early management of severe open tibiofibular fractures, reduce complication rates, and improve functional recovery, the Society of Microsurgery of the Chinese Medical Association organized a panel of domestic experts to develop the Evidence-based guideline for the diagnosis and early fixation of severe open tibiofibular fractures ( version 2025), using evidence-based methodology. The guidelines provided 12 recommendations covering diagnostic and early fixation strategies of severe open tibiofibular fractures, aiming to provide clinicians with scientifically grounded and standardized guidance.
