bjective To analyze the growth trends of height and weight among primary and secondary school students, and explore the developmental characteristics and gender differences at different age groups, and to provide a scientific basis for adolescent health policy formulation. Methods Based on 675 175 health examination records of 227 978 students aged 6-17 years in Shiyan City from 2015 to 2024, a logistic growth model was employed to fit the curves of height and weight changes with age. Results From 2015 to 2024, height and weight showed steady increases across all age groups, exhibiting typical sigmoidal growth patterns. The growth rates varied across age groups: the younger age group (6-9 years) showed a moderate growth (annual height increase of 0.5-1.0 cm, weight increase of 0.03-0.06 kg/year), while the older age group (10-17 years) demonstrated a significant growth (annual height increase of 1.5-2.0 cm, weight increase of 0.22-0.38 kg/year). The growth rate curves displayed a unimodal distribution. The growth inflection points of male students occurred later than that of female students (height inflection point: 9.87 years for males vs. 8.98 years for females; weight inflection point: 10.70 years for males vs. 9.99 years for females). Female students experienced a more concentrated but shorter period of growth and development. The peak height growth rate was 7.40 cm/year at age 9 for females and 7.09 cm/year at age 10 for males, while the peak weight growth rate was 5.04 kg/year at age 10 for females and 5.27 kg/year at age 11 for males. Conclusion The physical development of primary and secondary school students in Shiyan City follows a logistic growth pattern, with significant gender differences and characteristics of adolescent growth spurts. Female students exhibit an earlier and more concentrated growth process.

ObjectiveTo investigate the effect of Sanet Vision Integrator (SVI)-based visuomotor integration training on the severity of neglect symptoms, upper limb motor function and activities of daily living (ADL) in patients with post-stroke unilateral spatial neglect (USN). MethodsFrom July, 2023 to September, 2025, 41 patients with post-stroke USN in Beijing Bo'ai Hospital were enrolled and randomly assigned to control group (n = 20) and experimental group (n = 21). Both groups received conventional rehabilitation and visual scanning training, while the experimental group received supplementary SVI-based visuomotor integration training, including saccadic, rotation and hand-eye coordination training, for eight weeks. They were assessed with Chinese Behavioral Inattention Test-Hong Kong version (CBIT-HK), Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and modified Barthel Index (MBI) before and after treatment. ResultsAfter treatment, all the scores significantly improved in both groups (|t| > 4.004, P < 0.001), and the total scores of CBIT-HK and the core visual search sub-items (star cancellation, line crossing and letter cancellation), FMA-UE and MBI were better in the experimental group than in the control group (t > 2.096, P < 0.05). ConclusionSVI-based visuomotor training can effectively alleviate the USN symptoms, broaden the span of visual attention, facilitate the functional recovery of the affected upper extremity, and improve ADL in patients after stroke.

Objective:To analyze the predictive role of WT1 expression levels pre-and early post-transplantation on relapse and overall survival(OS)in patients with acute myeloid leukemia(AML)undergoing allogeneic hematopoietic stem cell transplantation(allo-HSCT)during their first complete remission(CR1).Methods:A retrospective analysis was conducted on the clinical data of 107 adult AML patients who underwent allo-HSCT during their CR1 at our center between May 2012 and December 2021.The predictive role of bone marrow WT1 expression levels before transplantation and at 3 and 6 months post-transplantation on relapse and OS was explored in combination with relevant clinical factors.Results:The median follow-up time for the 107 patients was 70(range:11-117)months.Among the patients,15 cases died.Kaplan-Meier survial analysis showed that the 3-year overall survival(OS)rate was 85.0％.20 patients experienced relapse,with a median time to relapse of 8(range:0.5-44)months and a l-year cumulative relapse rate of 13.1％.The overall median value of WT1 before transplantation,3 months after transplantation,and 6 months after transplantation was 0.26％(range:0％-23.64％),with an upper quartile value of 0.74％.No statistically significant differences in WT1 expression levels were observed among the pre-transplantation,3-month post-transplantation,and 6-month post-transplantation time points(P=0.227).Univariate analysis showed that patients with WT1 levels＞0.74％at 3 months post-transplantation had a higher 1-year relapse rate(P=0.029)and lower 3-year OS rate(P＜0.001)compared to patients with WT1 levels ≤0.74％.Other significant factors affecting 1-year relapse included stem cell source(P=0.041)and chronic graft-versus-host disease(cGVHD)(P=0.013).For 3-year OS,additional influencing factors were genetic high risk(P=0.048)and stem cell source(P=0.016).Multivariate analysis revealed that WT1 level＞0.74％at 3 months post-transplantation had a trend to affect 1-year relapse rate(HR=3.309,95％CI:0.958-11.431,P=0.058),while the absence of cGVHD was an independent risk factor for 1-year relapse(HR=3.473,95％CI:0.749-16.100,P=0.037).Only WT1 level＞0.74％at 3 months post-transplantation was an independent risk factor for 3-year OS(HR=6.886,95％CI:2.402-19.738,P＜0.001).Conclusion:High WT1 expression level at 3 months post-transplantation in AML patients undergoing allo-HSCT during CR1 affects the 1-year relapse rate and 3-year OS,and is an independent risk factor affecting 3-year OS.These findings suggest that dynamic monitoring of WT1 expression levels has certain value in prognostic assessment of AML patients who received allo-HSCT during CR1.

Rheumatoid arthritis(RA)is characterized by bidi-rectional bone remodeling imbalance,clinically termed the "high resorption-low formation" paradox,stemming not only from osteoclast hyperactivation but also critically involving pro-found suppression of osteoblast differentiation and function.No-tably,this suppression cannot be fully attributed to osteoclast hyperactivity;synovium-resident immune cells exert a pivotal regulatory influence through distinct mechanisms.This review systematically examines how synovial immune cells orchestrate bone remodeling in RA through both paracrine cytokine networks and direct cell-cell communication with bone lineage cells,thereby perturbing physiological homeostasis and driving patho-logical progression.These mechanistic revelations yield innova-tive perspectives on RA pathogenesis,positioning immune-medi-ated osteoimmune dysregulation as a promising therapeutic fron-tier for targeted intervention.

Objective To investigate the risk factors of adverse events in elderly patients with painless gastroenteroscopy,and construct a nomogram model for predicting the risk of adverse events.Methods 302 patients who underwent painless gastroenteroscopy from September 2023 to March 2024 were retrospectively enrolled and randomly divided into training set(211 cases)and validation set(91 cases)according to the 7∶3 ratio.The training set was divided into adverse event group(64 cases)and non-adverse event group(147 cases)according to whether adverse events occurred.Multivariate Logistic regression analysis was used to screen the risk factors for adverse events in elderly painless gastroenteroscopy patients,R 3.4.3 software was used to construct a nomogram model,and the validation set was used for external verification.The nomogram model discrimination was evaluated by drawing the receiver operator characteristic curve(ROC curve),and the calibration curve was drawn to evaluate the calibration degree of the nomogram model.Results Univariate analysis showed that,the comparison of overweight or obesity,smoking,hypertension,coronary heart disease,education level,pre examination sleep time,and exercise habits between the adverse event group and the non-adverse event group were statistically significant(P＜0.05);Multivariate Logistic regression analysis showed that overweight or obesity(OR=4.821,95％CI:1.052～11.651),smoking(OR=1.056,95％CI:1.313～3.109),hypertension(OR=1.356,95％CI:1.175～2.677),and coronary heart disease(OR=1.385,95％CI:1.168～2.765)were risk factors for adverse events during painless gastroenteroscopy in elderly patients(P＜0.05);The areas under the ROC curves for the training and validation sets were 0.921 and 0.795,respectively.The sensitivity was 90.62％(95％CI:0.846～0.965)and 82.14％(95％CI:0.689～0.856),and the specificity was 74.83％(95％CI:1.056～2.939)and 76.19％(95％CI:1.245～4.161),indicating that the nomogram model had good discriminability;The Hosmer-Lemeshow goodness of fit test results showed that the nomogram model had a good fit(P＞0.05),and the calibration curves of the training and validation sets both showed that the nomogram model had a good consistency between the actual and predicting incidence of adverse events(P＞0.05).Conclusion Overweight or obesity,hypertension,cornary heart disease and smoking are independently correlated with adverse events in painless gastroenteroscopy,and the nomogram model constructed based on the above factors to predict the risk of adverse events in painless gastroenteroscopy has good predictive efficacy.

Objective:To investigate the expression of indoleamine 2,3-dioxygenase 1(IDO1)in different types of breast cancer tissues and its relationship with patient prognosis and immune cell infiltration.Methods:RNA sequencing data of breast cancer and corresponding clinical information from the TCGA database were collected.The differential expression of IDO1 mRNA in various breast cancer tissues(different subtypes,stages,menopause statuses,and age groups)and adjacent normal tissues were analyzed.Breast cancer patients with significant differences in IDO1 mRNA expression were divided into high and low expression groups,and their disease-specific survival(DSS)was compared between the two groups.The relationship between IDO1 mRNA expression and immune cell infiltration in cancer tissues with significant DSS differences was analyzed.Immunohistochemistry was used to detect IDO1 protein expression in ER-negative,PR-negative,HER2-positive,and stage Ⅱ breast cancer tissues,to verify the data from the database.Results:IDO1 mRNA was highly expressed in breast cancer tissues but varied across different breast cancer types.IDO1 mRNA was highly expressed in breast cancer tissues of patients with ER-negative,PR-negative,HER2-positive,HER2-negative subtypes,stage Ⅱ,T2 stage,N0 stage,M0 stage,premenopausal,postmenopausal,and age≤60 years(P<0.05 or P<0.01,or P<0.001).In the ER-negative,PR-negative,HER2-positive,and stage Ⅱ subgroups,breast cancer tissues patients with high IDO1 mRNA expression had significantly higher DSS than those with low expression(P<0.05 or P<0.01).In ER-negative,PR-negative,HER2-positive,and stageⅡ breast cancer tissues,IDO1 mRNA expression was associated with immune cell infiltration,including activated dendritic cells(aDCs),Th1 cells,T cells,CD56dim NK cells,CTLs,and Treg cells(all P<0.001).IDO1 protein was highly expressed in ER-negative,PR-negative,HER2-positive,and stage Ⅱ breast cancer tissues(all P<0.001),consistent with the data from the database.Conclusion:IDO1 expression varies across different types of breast cancer tissues.The expression of IDO1 is associated with the prognosis and immune cell infiltration in ER-negative,PR-negative,HER2-positive,and at stage Ⅱ breast cancer patients.

The medulla oblongata,situated at the caudal portion of the brainstem,serves as a critical regulatory center responsible for maintaining fundamental vital functions including respiratory and cardiovascular homeostasis.As a pivotal hub within the autonomic nervous system,it orchestrates the coordinated control of afferent and efferent neural pathways.Dysfunction of this region may precipitate life-threatening cardiorespiratory arrest,associated with substantial mortality rates.This case report presents a patient who developed acute extensive anterior myocardial infarction during treatment with dual antiplatelet therapy and moderate-intensity statins following acute medullary infarction.It is hypothesized that the pathogenesis may involve the acceleration of plaque erosion by the stroke-heart syndrome.This clinical case provides valuable insights into the complex neurocardiac interplay,particularly highlighting the imperative for enhanced recognition of brain-heart axis interactions in cerebrovascular pathology.
