Objective:To examine the status of self-perceived aging, family function, and fear of disease progression among elderly patients with peptic ulcer disease (PUD), and to explore the mediating role of self-perceived aging in the relationship between family function and fear of disease progression.Methods:This was a cross-sectional study. Using a convenience sampling method, a total of 307 elderly patients with PUD hospitalized in the Third Hospital of Bethune, Jilin University between December 2023 and May 2024 were included. Data were collected using the General Information Questionnaire, the Brief Ageing Perceptions Questionnaire (B-APQ), the Fear of Progression Questionnaire-Short Form (FoP-Q-SF), and the Chinese version of the Family Adaptability and Cohesion Evaluation Scales (FACES II-CV). The PROCESS macro in SPSS was used to construct and validate a mediation model to assess the mediating effect of self-perceived aging between family function and fear of disease progression among elderly patients with PUD.Results:A total of 307 questionnaires were distributed, with 276 valid responses obtained (effective response rate: 89.90%). The B-APQ score was (53.79±18.30), the FACES II-CV score was (92.17±16.39), and the FoP-Q-SF score was (30.16±6.02). Family function negatively predicted fear of disease progression directly, with a direct effect value of -0.083, accounting for 44.15% of the total effect (-0.083/-0.188). Self-perceived aging exerted a significant mediating effect between family function and fear of disease progression, with an indirect effect value of -0.105, representing 55.85% of the total effect (-0.105/-0.188) .Conclusions:This study reveals the mediating role of self-perceived aging in the relationship between family function and fear of disease progression in elderly PUD patients. The findings enrich the explanatory dimensions of psychosocial models in chronic disease management and underscore the importance of addressing family dynamics and aging perceptions in designing comprehensive interventions for elderly patients with digestive diseases.

Acute respiratory distress syndrome (ARDS) is a common respiratory emergency, but current clinical treatment remains at the level of symptomatic support and there is a lack of effective targeted treatment measures. Our previous study confirmed that inhalation of hydrogen gas can reduce the acute lung injury of ARDS, but the application of hydrogen has flammable and explosive safety concerns. Drinking hydrogen-rich liquid or inhaling hydrogen gas has been shown to play an important role in scavenging reactive oxygen species and maintaining mitochondrial quality control balance, thus improving ARDS in patients and animal models. Coral calcium hydrogenation (CCH) is a new solid molecular hydrogen carrier prepared from coral calcium (CC). Whether and how CCH affects acute lung injury in ARDS remains unstudied. In this study, we observed the therapeutic effect of CCH on lipopolysaccharide (LPS) induced acute lung injury in ARDS mice. The survival rate of mice treated with CCH and hydrogen inhalation was found to be comparable, demonstrating a significant improvement compared to the untreated ARDS model group. CCH treatment significantly reduced pulmonary hemorrhage and edema, and improved pulmonary function and local microcirculation in ARDS mice. CCH promoted mitochondrial peripheral division in the early course of ARDS by activating mitochondrial thioredoxin 2 (Trx2), improved lung mitochondrial dysfunction induced by LPS, and reduced oxidative stress damage. The results indicate that CCH is a highly efficient hydrogen-rich agent that can attenuate acute lung injury of ARDS by improving the mitochondrial function through Trx2 activation.

Objective: To investigate the prevalence of abnormal foot arch morphology and its associated factors among primary and secondary school students in Ganzhou City, so as to provide evidence for the prevention of such abnormalities. Methods: From November 2023 to May 2024, a questionnaire was conducted among 1 013 primary and secondary school students, who were selected from one primary school and one nine year continuous school with stratified cluster random sampling method. Professional equipment, including 2D foot scanning and plantar pressure plates, was utilized to screen pupils for abnormal foot arch morphology (including flatfoot and high arched foot). The Chi square was employed for intergroup comparisons, whilst multifactorial Logistic regression analysis was utilized to investigate the associated factors for the occurrence of foot morphological abnormality of arch among students. Results: The prevalence rate of flatfoot among primary and secondary school students at 61.1%, with bilateral cases accounting for 37.5% and unilateral cases for 23.6%; the prevalence of high arched foot was 8.0%, comprising 3.9% in both feet and 4.0% in one foot. The prevalence rates of flatfoot among boys and girls were 68.7% and 53.6% respectively. Multivariate Logistic regression analysis revealed that boys had a 1.45 times higher risk of developing flatfoot compared to girls ( OR =1.45, 95% CI = 1.05- 2.02), primary and secondary students aged 6-8 and 9-10 had 4.00, 3.81 times higher risk of flatfoot respectively compared to those aged 15-16 ( OR =4.00, 3.81, 95% CI =2.18-7.36, 2.08-6.99) (all P <0.05). Compared to girls, boys had a lower risk of developing high arched foot ( OR=0.52, 95%CI =0.28-0.95), primary and secondary students who frequently corrected their sitting and standing posture also had a lower risk of high arched foot ( OR = 0.30, 95% CI =0.10-0.88) (both P <0.05). Conclusions The prevalence of abnormal foot arch morphology among primary and secondary school students is relatively high, with exercise habits, and postural behaviour identified as associated factors. It is recommended to enhance early screening and behavioural interventions for key populations, thereby advancing the prevention and correction of foot morphological abnormality of arch.

OBJECTIVES: To study the significance of serum 25-hydroxyvitamin D₃ [25-(OH)D₃] level in the clinicopathological characteristics and prognosis of children with immunoglobulin A vasculitis nephritis (IgAVN). METHODS: A retrospective analysis was conducted on the clinical data of children with IgAVN who underwent renal biopsy at Suzhou Hospital Affiliated to Anhui Medical University and Jinling Hospital of the Medical School of Nanjing University from June 2015 to June 2020. Based on serum 25-(OH)D₃ level, the patients were divided into a normal group and a lower group. The clinicopathological characteristics and follow-up data of the two groups were collected and compared. RESULTS: A total of 359 children with IgAVN were included. Compared to the normal group (62 cases), the lower group (297 cases) exhibited higher incidences of hematochezia and gross hematuria, higher levels of serum creatinine, blood urea nitrogen, urinary retinol protein, urinary N-acetyl-β-D-glucosaminidase, and quantitative urinary protein, and a longer duration from renal biopsy to urinary protein becoming negative, as well as lower estimated glomerular filtration rate and albumin level (P<0.05). Renal pathology in the lower group showed a higher occurrence of tubular interstitial injury, crescent formation, segmental sclerosis in glomeruli, and inflammatory cell infiltration in the renal interstitium compared to the normal group (P<0.05). Survival analysis indicated that the cumulative renal survival rate was lower in the lower group (P<0.05). Multivariate Cox regression analysis revealed that low serum 25-(OH)D₃ level is an independent risk factor for poor prognosis in children with IgAVN. CONCLUSIONS Children with IgAVN and low serum 25-(OH)D₃ level have relatively severe clinicopathological manifestations. Low serum 25-(OH)D₃ level is an independent risk factor for poor prognosis in children with IgAVN.

Recent developments indicated that Bowman capsule rupture (BCR) is observed in antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis (AAGN). We aimed to explore the relationship between BCR and clinical manifestations, pathological changes, and prognosis in children with myeloperoxidase (MPO)-AAGN. Methods: A total of 56 children with MPO-AAGN were divided into BCR (+) and BCR (–) groups according to the status of Bowman’s capsule. Results: After retrospective analysis of the data, 24 children (42.9%) were found to have BCR. The results showed that BCR positively correlated with intrarenal immune cell infiltrates, obsolescence and crescents in glomeruli, tubulointerstitial inflammation, tubulitis, and tubular atrophy negatively correlated with normal glomeruli and immunoglobulin G deposition in the kidney. The clinical features and kidney pathological changes were more severe in the BCR (+) group than BCR (–) group, and the renal survival rate was significantly poorer in the BCR (+) group than BCR (–) group (χ2 = 5.45, p = 0.02). Moreover, estimated glomerular filtration rate (≤15 mL/ min/1.73 m2), BCR and ANCA renal risk score (ARRS) were independent risk factors for the development of end-stage kidney disease (ESKD) in children with MPO-AAGN. After combining BCR with the Berden classification and ARRS, our data suggested that the Berden classification + BCR and ARRS + BCR showed better predictive values for ESKD than those of the Berden classification and ARRS, respectively. Conclusion: BCR is an important pathological lesion that correlates with severe clinical manifestations, pathological changes, and poor prognosis in children with MPO-AAGN.
