To analyze the disease burden of acute lymphoid leukemia(ALL) and its changing trends in China and globally from 1990 to 2021, aiming to provide a theoretical basis for disease prevention, treatment, and policy formulation. Data on the incidence, prevalence, mortality, and disability adjusted life years(DALYs) of ALL in China and globally from 1990 to 2021 were extracted from the Global Burden of Disease(GBD) 2021 database. The Joinpoint regression model was used to calculate the average annual percentage change(AAPC) to assess the trends in disease burden. Decomposition analysis was employed to identify and quantify the contributions of different factors to the changes in ALL disease burden. The population attributable fraction(PAF) was used to compare the risk factors for ALL in China and globally in 1990 and 2021. Stratified by the sociodemographic index(SDI), the locally estimated scatterplot smoothing(LOESS) method was used to assess the association between age-standardized incidence rate(ASIR), age-standardized mortality rate(ASMR), and SDI. The incidence-mortality ratio(IMR) was calculated to evaluate the diagnostic level and current treatment status of ALL. From 1990 to 2021, ASIR of ALL in the Chinese population increased from 3.385/100 000 to 3.637/100 000(AAPC: 0.005), the age-standardized prevalence rate(ASPR) increased from 6.596/100 000 to 22.022/100 000(AAPC: 0.478), the ASMR decreased from 3.051/100 000 to 1.357/100 000(AAPC: -0.056), and the age-standardized DALYs rate(ASDR) decreased from 195.792/100 000 to 74.063/100 000(AAPC: -3.996). Globally, the corresponding figures were: ASIR decreased from 1.789/100 000 to 1.371/100 000(AAPC: -0.014), ASPR increased from 4.122/100 000 to 5.425/100 000(AAPC: 0.039), ASMR decreased from 1.551/100 000 to 0.898/100 000(AAPC: -0.021), and ASDR decreased from 94.894/100 000 to 48.858/100 000(AAPC: -1.494). During this period, the aforementioned disease burden indicators were generally higher in males than in females, both in China and globally.In 2021, the peak incidence of ALL in China and globally was primarily concentrated in the 0-19 years age group, with the highest rate observed in those under 5 years of age. The burden of prevalence and DALYs was also mainly concentrated in this age group. Regarding mortality, the death burden in China was predominantly observed in the older adult age group, particularly among those aged ≥60 years. Globally, the mortality burden was highest in the under-5 age group, while remaining at a relatively high level in the older adult population. SDI correlation analysis based on data from 204 countries/regions globally from 1990 to 2021 showed that ASIR gradually increased with increasing SDI, whereas ASMR showed an initial increase followed by a decreasing trend. The ASIR and ASMR for the overall Chinese population and by sex were higher than expected. PAF results indicated that smoking and high body mass index were the main attributable risk factors for ALL mortality and DALYs burden, with their contribution consistently increasing. Decomposition analysis revealed that population growth and epidemiological changes were the primary drivers behind the changes in ALL incidence and mortality burden. Compared with 1990, the IMR for ALL in both China and globally increased in 2021. Over the past three decades, the ASMR and ASDR for ALL in China and globally have generally declined. During the same period, the ASIR and ASPR for ALL increased in China, while globally, the ASIR decreased and the ASPR increased. However, the disease burden of ALL remains high in males, children, and the older adult population. Differentiated prevention and control measures should be implemented in accordance with changes in SDI. The findings highlight the importance of strengthening prevention and early diagnosis, and suggest the need for targeted screening and treatment strategies for different age and sex groups. Concurrently, attention should be paid to the role of weight management and tobacco control in comprehensive prevention and control efforts to further reduce the disease burden of ALL.

Implementation science (IS) aims to systematically analyze and address the real-world gaps from evidence to practice and the influencing factors of the context. It is necessary to carry out qualitative research to gather relevant implementation outcomes. Nevertheless, traditional qualitative analysis has issues such as consuming a great deal of time and energy, and it is unable to promptly provide the crucial data required for implementation science research. The Rapid Qualitative Analysis (RQA) method, through semi-structured interviews and the adoption of techniques such as immediate data condensation and matrix analysis, can effectively shorten the cycle of qualitative data collection and data processing. RQA can promptly identify social determinants of health such as structural barriers, facilitators, and the behavioral characteristics of target groups. It provides a real-time basis for public health decision-making, the interpretation of complex social phenomena, and the process and effectiveness evaluation of research projects. Although RQA is difficult to conduct in-depth theoretical analysis based on grounded theory, its efficiency and flexibility make it the preferred tool for large-scale and time-sensitive research. Thus, it has been widely applied in implementation science research. This paper sorts out the core concepts and commonly used technical methods of RQA, as well as the differences between RQA and traditional qualitative analysis. It also explores the applications of RQA in intervention optimization, process evaluation, and implementation outcome evaluation. By integrating specific cases, this paper clarifies its application value in the field of implementation science. In the future, it is advisable to explore the integration of RQA with technologies such as artificial intelligence and big data, in order to bridge the gap between the transformation of scientific research achievements into practice. Under circumstances of limited resources or tight time constraints, RQA can be used to efficiently conduct implementation science research, providing convenient and scientific methodological and technical support for accelerating evidence-based practice.

High myopia has become a major public health concern worldwide, particularly in China and Southeast Asia. It is associated not only with a variety of fundus diseases but also with earlier onset and greater severity of cataracts, resulting in significant visual impairment. Phacoemulsification is currently the main surgical treatment for cataracts. However, intraoperative fluctuations in perfusion pressure and exposure to ultrasonic energy may affect the vitreoretinal structures, potentially accelerating the progression of fundus pathology after surgery in highly myopic eyes. This article summarizes current evidence on the progression of posterior scleral staphyloma, myopic maculopathy, and retinal detachment following phacoemulsification in highly myopic eyes.

AIM: To observe the preoperative and postoperative clinical efficacy of comprehensive dry eye treatment in cataract patients complicated with diabetes mellitus, with a focus on comparing the differences between the two groups in terms of postoperative dry eye symptoms, tear film function, visual recovery, and complication rates, aiming to provide an effective protocol for the perioperative management and long-term prognosis improvement in this patient population.METHODS:Patients diagnosed with both cataract and diabetes mellitus and presenting with varying degrees of dry eye symptoms, scheduled for cataract surgery at the hospital from May 2023 to December 2024, were enrolled as study subjects. They were divided into two groups using a random number method: the control group received sodium hyaluronate eye drops alone, and the experimental group underwent comprehensive preoperative dry eye treatment(sodium hyaluronate eye drops+warm compress+meibomian gland cleaning and massage+Chinese herbal fumigation+health guidance). Tear film breakup time(BUT), corneal fluorescein staining(FL), Ocular Surface Disease Index(OSDI)score, tear meniscus height(TMH), and non-invasive first tear film breakup time(NIBUT)were compared between the two groups before and after 4 wk of treatment. Meibomian gland loss, tear film lipid layer thickness, and basic ocular symptoms were also assessed.RESULTS:This study included 60 eyes of 60 patients, with a control group of 30 eyes of 30 patients(aged 56.24±10.24 y, 13 males and 17 females)and an experimental group of 30 eyes of 30 patients(aged 58.01±9.79 y, 15 males and 15 females).After 4 wk of preoperative treatment, the BUT in the experimental group increased from 4.09±1.13 s to 10.35±1.46 s, and from 4.15±1.05 s to 8.26±1.36 s in the control group, showing a significant intergroup difference(t=5.737, P<0.001). The FL score in the experimental group decreased from 6.83±0.46 points to 2.86±0.38 points, whereas in the control group it decreased from 6.79±0.39 points to 5.32±0.43 points(t=23.480, P<0.001). After 4 wk of treatment, the NIBUT in the experimental group increased from 5.19±1.12 s to 9.36±1.47 s, compared to an increase from 5.21±1.04 s to 7.18±1.25 s in the control group(t=6.188,P<0.001). The proportion of patients with a thin tear film lipid layer was significantly higher in the experimental group than in the control group(all P<0.01). Ocular clinical symptoms decreased after treatment in both groups, with the experimental group showing lower scores than the control group(all P<0.001).CONCLUSION:Preoperative comprehensive dry eye treatment can multi-dimensionally improve dry eye symptoms and tear film stability in cataract patients with diabetes mellitus, providing an effective strategy for the perioperative management of cataract patients.

Non-invasive prenatal testing (NIPT) based on fetal free DNA is a non-invasive technique to screen for common fetal aneuploidies by analyzing cell-free fetal DNA (cffDNA) in the peripheral blood of pregnant women. This technique has opened a new era of prenatal screening for its high safety and reliability. In recent years, it has been shown that NIPT can not only screen for fetal aneuploidies, but may also reveal maternal genomic abnormalities. The incidental detection of maternal tumors has aroused widespread concern in the clinical settings. The aim of this review is to systematically summarize the research progress of NIPT technique in incidental detection of maternal tumors, and to discuss its clinical significance, technical challenges, and future development direction. It has been found that multiple chromosome aneuploidies (MCAs) in NIPT detection is one of the important biomarkers suggesting occult maternal malignant tumors. In this paper, the relevant progress of NIPT technique in the incidental discovery of maternal tumors were reviewed in order to provide a reference for individualized and standardized application of NIPT technique in maternal health monitoring.

Objective:
To explore the relationship of social anxiety and emotion regulation strategy with short video addiction among college students, so as to provide reference for alleviating social anxiety, improving the level of emotion regulation and preventing short video addiction.
Methods:
From May to June 2024, 2 172 college students from a university in Guangzhou were selected by multistage random cluster sampling method. The Interaction Anxiousness Scale, Emotion Regulation Questionnaire and Short Video Addiction Scale were used as the measurement tools. The potential profile was used to analyze the potential categories of social anxiety and emotion regulation strategy. The Chi square test was used to analyze the characteristics of the distribution of potential profile categories of college students with different demographic characteristics. Multiple linear regression analysis was used to analyze the relationship between social anxiety, emotion regulation strategy and short video addiction.
Results:
The potential categories of social anxiety and emotion regulation strategy in college students were divided into adaptive regulation type (784 cases, 36.10 %), low anxiety-expression type (623 cases, 28.68%), inhibition-anxiety type (478 cases, 22.01%), high anxiety-disorder type (287 cases, 13.21%). There were statistically significant differences in the distribution of various potential categories of social anxiety and emotion regulation strategy among cadres of different gender, family residence, class cadres or not ( χ 2=42.55, 17.86 , 39.05, all P <0.01). Multiple linear regression analysis showed that after controlling the confounding factors such as demographic variables, the potential categories of social anxiety and emotion regulation strategy of college students (low anxiety-expression type, inhibition-anxiety type, high anxiety-disorder type) were the important related factors of short video addiction ( β =0.15,0.25,0.35, all P <0.05).
Conclusions
Social anxiety and emotion regulation strategy of college students exhibit distinct categorical characteristics, and its varying latent categories are associated with short video addiction. Schools should implement targeted intervention measures for different categories of college students to promote their comprehensive mental health development.
7.Epidemiological characteristics of category C intestinal infectious diseases among children and adolescents in Shenzhen from 2012 to 2024 and the association with meteorological factors
Chinese Journal of School Health 2026;47(4):553-557
Objective:
To analyze the epidemiological characteristics of category C intestinal infectious diseases among children and adolescents in Shenzhen from 2012 to 2024 and the association with meteorological factors, so as to provide a scientific basis for the targeted prevention and control of infectious diseases for children and adolescents.
Methods:
Using data from the "Infectious Disease Reporting Information Management System" of the "China Disease Prevention and Control Information System" covering the period from January 1, 2012 to December 31, 2024, the study analyzed clinical and confirmed cases of hand, foot, and mouth disease, other infectious diarrhea, and acute hemorrhagic conjunctivitis among individuals aged 6-19 years old to describe demographic and temporal characteristics. It used Joinpoint regression to calculate the average annual percent change (AAPC) and annual percent change (APC) to analyze incidence trends, and Spearman s correlation was combined to generalize linear models so as to assess the association between category C intestinal infectious diseases and meteorological factors.
Results:
From 2012 to 2024, a cumulative total of 61 019 cases of hand, foot, and mouth disease among children and adolescents, 58 498 cases of other infectious diarrhea, and 6 377 cases of acute hemorrhagic conjunctivitis were reported. The AAPC in the incidence rates of these three diseases was 19.19%, 31.03% and 31.48 %, respectively(all P <0.05). Notably, the incidence of hand, foot, and mouth disease increased significantly after 2022 (APC= 133.66 %, P <0.01). The temporal distribution showed that hand,foot,and mouth disease was most prevalent in May,June and July (seasonal index of 2.39,3.64,1.97), other infectious diarrhea was most prevalent in February,March and December (seasonal index of 1.22,1.25,1.47), and acute hemorrhagic conjunctivitis peaked in September and October (seasonal index of 4.22,2.16). Monthly average temperature could increase the risk of hand,foot,and mouth disease( β = 0.18 ,95% CI =0.11-0.25); as monthly average wind speed increased, the incidence of other infectious diarrhea ( β =-0.86, 95% CI = -1.50 to -0.22) and acute hemorrhagic conjunctivitis ( β =-1.32, 95% CI =-2.60 to -0.05) both decreased (all P < 0.05 ).
Conclusions
Among children and adolescents in Shenzhen, category C intestinal infectious diseases remain prevalent throughout the year;the number of reported hand, foot, and mouth disease cases has shown an upward trend in recent years.Temperature and wind speed significantly affect the number of reported cases of three types with category C intestinal infectious diseases.

Objective:
To understand the epidemiological characteristics and disease burden of influenza like illness (ILI) among student populations, so as to provide data support for policy formulation and optimal allocation of health resources.
Methods:
From January 2024 to February 2025, a questionnaire survey was conducted among parents of kindergarten, primary school, junior and senior high school students in 9 districts of Shenzhen, including Longhua, Futian, Bao an, Longgang, Luohu, Nanshan, Guangming, Pingshan and Yantian. Parents were asked to complete the questionnaire based on whether their children had fever, cough, vomiting, diarrhea, rash and other common symptoms in 2024. A total of 3 537 parents were investigated, and 444 ILI cases were included as study subjects. The epidemiological burden, including incidence rate of influenza, visitation rate, years lived with disability (YLDs) and economic burden (including direct economic burden, indirect economic burden and intangible burden) were analyzed.
Results:
The incidence rate of influenza among students in Shenzhen in 2024 was 12.55%. The ILI incidence rates in kindergarten, primary school, junior and senior high school were 14.01%, 11.69% and 5.23%, respectively, with a statistically significant difference ( χ 2= 45.20, P <0.01). The ILI consultation rate among students was 85.36%, and the consultation rates in kindergarten (87.36%) and primary school students (84.62%) were higher than those in junior and senior high school students ( 56.52 %) ( χ 2=16.47, P <0.01). A total of 78.88% of cases did not receive etiological detection.The median total economic burden per ILI case was 2 354.62 yuan, including direct medical costs of 300.00 yuan, direct non medical costs of 212.50 yuan, indirect costs of 1 000.00 yuan, and intangible burden of 500.00 yuan.
Conclusions
Schools are high risk environment for influenza, and younger students are a high risk group for ILI. The disease burden caused by student ILI remains substantial.

ObjectiveTo delineate imaging findings using an imaging platform and investigate the correlation between MRI characteristics of spinal cord atrophy and clinical diagnosis in children with spinal cord injury (SCI). MethodsImaging data of 150 children with SCI admitted to Beijing Bo'ai Hospital, China Rehabilitation Research Center, from January, 2002 to March, 2024 were collected and imported into the imaging platform. The anteroposterior and transverse diameters of the middle part of the spinal cord at the cross-section with the most severe atrophy were measured, and the relevant indicators of the previous normal spinal cord segment were measured as controls; the radiomic features were extracted. Clinical data of the children including gender, age, cause of injury, sensory level, motor level, spinal cord injury level, injury severity and disease course were collected. ResultsSpinal cord atrophy was identified in 81 cases (54%), among which 78 cases (96%) were American Spinal Injury Association Impairment Scale (AIS) grade A and 3 cases (4%) were AIS grade C. The upper boundary of the spinal cord atrophy site strongly correlated with the injury level, motor level and sensory level (r > 0.8, P < 0.001). ConclusionMore than half of children with SCI may develop secondary spinal cord atrophy, the vast majority of whom suffer from complete spinal cord injury; the upper boundary of spinal cord atrophy is correlated with the injury level.

Wilson disease (WD) is one of the few treatable neurogenetic disorders. Currently, Western medicine remains the main treatment method for WD, while since the 1990s, multiple studies conducted by Professor Yang Renmin and his team have shown that traditional Chinese medicine (TCM) also has a favorable therapeutic effect. Based on the principle of low-copper diet for WD, this article systematically elaborates on the advantages, limitations, and key considerations of current Western medicine therapies (pharmacotherapy, liver transplantation, and splenectomy) and reviews the research findings of TCM in China, especially the wide application of Gandou Decoction in clinical practice. Studies have shown that Gandou Decoction can effectively improve neurological symptoms, protect hepatic and renal function, and avoid the adverse drug reactions associated with metal chelating agents, and therefore, it can be used an effective long-term adjuvant therapy for WD. It should be noted that symptoms and signs should be considered in integrated traditional Chinese and Western medicine therapy for WD, and high-copper TCM drugs should be avoided to prevent deterioration.
