AIM:To observe the defocus state and myopia control in myopic children wearing single-vision, defocus, and orthokeratology lenses using multispectral refraction topography(MRT).METHODS: A total of 279 myopic patients aged 8-14 years old, with a spherical equivalent(SE)from -7.00 to -0.50 D, treated at the Chengdu Aier Eye Hospital from June 2022 to December 2023. Patients who volunteered for the study were assigned to three groups. A total of 94 cases were provided with single-vision spectacle lenses(SVL group), 90 cases received individualized ocular refraction customization(IORC group), and 95 cases received orthokeratology lenses(OK group). Simultaneously, the three groups were further categorized into low(-3.00 to -0.50 D), moderate(-6.00 to -3.25 D), and high myopia(-7.00 to -6.25 D)groups according to different SE. MRT was used to measure and compare the defocus changes of the retina in supperior, inferior, nasal, and temporal quadrants(RDV-S, RDV-I, RDV-N, RDV-T), and three angles of field of view, including 0-15°, 15°-30°, and 30°-45°(RDV-15, RDV-30, RDV-45)in the three groups(the data divide for the connected regions is grouped to the latter group). A one-way analysis of variance was used for intergroup comparisons. Univariate and multivariate linear regression analyses were used to analyze the factors related to changes in the axial length(AL)at 1 a after intervention.RESULTS:There were significant differences in 1-year SE and AL growth among patients in the SVL, IORC, and OK groups before and after intervention(P<0.001). The 1-year SE and the difference of AL growth in patients with low myopia was significantly different among SVL, IORC, and OK groups(P<0.001); however, there was no significant difference between the IORC and OK groups(P>0.05); there were significant differences in the SE and AL growth changes between the OK group and the IORC and SVL groups in moderate myopia(P<0.001); and there were significant differences between the OK group and the IORC and SVL groups in SE and AL growth of high myopia group after wearing lenses for 1 a(P<0.001), while there were no significant differences between the IORC and SVL groups(P>0.05). In addition, there were significant differences in the relative peripheral refractive errors(RPRE)of 4 quadrants and 3 eccentric regions among the three groups of patients in different degrees of myopia groups(P<0.001). Pair-wise comparison of the growth difference of eccentric D-RDV-15 in low myopia group after wearing lenses for 1 a showed significant differences between the SVL, IORC, and OK groups(P<0.001), but no significant differences between the IORC and OK groups(P>0.05). The angle of field of view D-RDV-30 in moderate myopia subgroups was statistically different between the SVL group and the IORC and OK groups after wearing lenses for 1 a(P<0.001), while the IORC and OK groups showed no significant differences(P>0.05); the angle of field of view D-RDV-15 in high myopia subgroups was statistically different between the OK group and the IORC and SVL groups after wearing lenses for 1 a(P<0.001), but there was no significant difference between the IORC and SVL groups(P>0.05). Univariate and multivariate linear regression model analysis showed that the changes in D-TRVD, D-RDV-45, D-RDV-N, and D-RDV-I correlated with the increase in the difference in 1 a AL.CONCLUSION: MRT can be used to guide the clinical control of myopia. Myopia development is related to the peripheral retinal defocus state, and the difference of defocus quantity in the inferior nasal side at 30°-45° eccentricity may be a factor regulating the rapid progression of myopia.

As the volume of medical research using large language models (LLM) surges, the need for standardized and transparent reporting standards becomes increasingly critical. In January 2025, Nature Medicine published statement titled by TRIPOD-LLM reporting guideline for studies using large language models. This represents the first comprehensive reporting framework specifically tailored for studies that develop prediction models based on LLM. It comprises a checklist with 19 main items (encompassing 50 sub-items), a flowchart, and an abstract checklist (containing 12 items). This article provides an interpretation of TRIPOD-LLM’s development methods, primary content, scope, and the specific details of its items. The goal is to help researchers, clinicians, editors, and healthcare decision-makers to deeply understand and correctly apply TRIPOD-LLM, thereby improving the quality and transparency of LLM medical research reporting and promoting the standardized and ethical integration of LLM into healthcare.

Intestinal aging is central to systemic aging, characterized by a progressive decline in intestinal structure and function. The core mechanisms involve dysregulation of epithelial cell renewal and gut microbiota dysbiosis. In addition to previous results in model organisms like Drosophila melanogaster, recent studies have shown that in mammalian models, aging causes increased intestinal permeability and intestinal-derived systemic inflammation, thereby affecting longevity. Therefore, anti-intestinal aging can be an important strategy for reducing frailty and promoting longevity. There are three key gaps remaining in the study of intestinal aging: (1) overemphasis on aging-related diseases rather than the primary aging mechanisms; (2) lack of specific drugs or treatments to prevent or treat intestinal aging; (3) limited aging-specific dysbiosis research. In this review, the basic structures and renewal mechanisms of intestinal epithelium, and mechanisms and potential therapies for intestinal aging are discussed to advance understanding of the causes, consequences, and treatments of age-related intestinal dysfunction.

OBJECTIVES:
To investigate the therapeutic mechanism of Danzhi Jiangtang Capsule (DZJTC) for repairing renal vascular endothelial injury in rats with diabetic nephropathy (DN).
METHODS:
Fifty male SD rat models of DN, established by left nephrectomy, high-sugar and high-fat diet and streptozotocin injection, were randomized into DN model group, low-, medium-, and high-dose DZJTC treatment groups, and DAPT (a γ-secretase inhibitor) treatment group, with 10 rats with normal feeding as the control group. DZJTC was administered by daily gavage at 0.315, 0.63, or 1.26 g/kg, and DAPT (20 mg/kg, dissolved in 50% CMC-Na solution) was given by gavage every other day for 4 weeks; normal saline was given in the control and model groups. After treatment, the levels of creatinine (CRE), blood urea nitrogen (BUN), and microalbuminuria (mALB) were detected with ELISA, and renal pathologies were observed by transmission electron microscopy. Renal expressions of vascular endothelial growth factor (VEGF) and endothelin-1 (ET-1) were measured by immunohistochemistry, and the protein expressions of CD31 and Notch signaling pathway components were detected using Western blotting.
RESULTS:
The rat models of DN showed significantly increased CRE, BUN, and mALB levels, obvious renal pathologies under electron microscopy, increased renal VEGF, ET-1 and CD31 expressions, and upregulated Notch1, NICD, and MAML1 protein levels. Treatment with DZJTC at the 3 doses and DAPT significantly reduced CRE, BUN, and mALB levels, improved renal pathology, decreased VEGF, ET-1 and CD31 expressions, and lowered Notch1, NICD and MAML1 levels, and the effects were the most pronounced with high-dose DZJTC.
CONCLUSIONS
DZJTC ameliorates hyperproliferation and dysfunction of renal vascular endothelium in DN rats possibly by regulating renal VEGF and ET-1 levels via inhibiting NICD- and MAML1-mediated Notch signaling pathway.

Adolescent depression is increasingly recognized as a serious mental health disorder with distinct clinical and molecular features. Using single-nucleus RNA sequencing, we identified cell-specific transcriptomic changes in the nucleus accumbens (NAc), particularly in astrocytes, of adolescent macaques exhibiting depressive-like behaviors. The level of diacylglycerol kinase beta was significantly reduced in neurons and glial cells of depressed macaques, while FKBP5 levels increased in glial cells. Disruption of GABAergic synapses and disruption of D-glutamine and D-glutamate metabolism were linked to depressive phenotypes in medium spiny neurons (MSNs) and subtypes of astrocytes. Communication pathways between astrocytes and D1/D2-MSNs were also disrupted, involving factors like bone morphogenetic protein-6 and Erb-B2 receptor tyrosine kinase-4. Bulk transcriptomic and proteomic analyses corroborated these findings, and FKBP5 upregulation was confirmed by qRT-PCR, western blotting, and immunofluorescence in the NAc of rats and macaques with chronic unpredictable mild stress. Our results highlight the specific roles of different cell types in adolescent depression in the NAc, offering potential targets for new antidepressant therapies.

Objective:To analyze the clinical characteristic of systemic juvenile idiopathic arthritis (sJIA) patients with Kawasaki disease like onset symptom.Methods:A case-control study was performed. A total of 24 patients with sJIA with Kawasaki disease-like symptoms at the Department of Rheumatology and Immunology, Children′s Hospital of Chongqing Medical University from January 2018 to August 2024 were selected as the Kawasaki disease combined with sJIA group. A total of 96 patients with Kawasaki disease as the Kawasaki disease group and 83 patients with sJIA were selected as the sJIA group. The general information, clinical manifestations, laboratory examinations and complications of the patients were compared among the 3 groups. Differences between groups were assessed by Mann-Whitney U test or Kruskal-Wallis H test and Chi-square test or Fisher's exact test. Results:There were significant differences in age and fever course between Kawasaki disease combined with sJIA groups, Kawasaki disease groups, and sJIA groups (3.4 (2.5, 7.3) vs. 3.4 (1.9, 4.8) vs. 8.8 (5.1, 11.7) years, 24.5 (18.0, 37.3) vs. 23.0 (18.0, 31.0) vs. 7.0 (6.0, 8.0) d, Z=67.09, 138.24, both P<0.05). Among the 24 cases of Kawasaki disease combined with sJIA, 20 cases (83%) had joint symptoms and 9 cases (38%) had conjunctival congestion. There were significant differences in the incidence of coronary artery injury between Kawasaki disease combined with sJIA group, Kawasaki disease group and sJIA group (58% (14/24) vs. 44% (42/96) vs. 6% (5/83), χ2=40.50, P<0.05). There were significant differences in the risk of macrophage activation syndrome between Kawasaki disease combined with sJIA group, sJIA group and Kawasaki disease group (17% (4/24) vs. 10% (8/83) vs. 0, P<0.05). In the Kawasaki disease combined with sJIA group, 11 cases (46%) did not respond after 2 courses of intravenous immunoglobulin (IVIG) treatment, and 21 cases (88%) used glucocorticoids. The use rate of high-dose hormones in the Kawasaki disease combined with sJIA group was higher than that in the sJIA group (29% (7/24) vs. 5% (4/83), χ2=12.95, P<0.05). In the group of Kawasaki disease combined with sJIA group, 17 cases (71%) used biological agents, 1 case used adalimumab, and 16 cases received tocilizumab treatment, of which 4 cases were allergic to tocilizumab. In the group of Kawasaki disease combined with sJIA, 11 cases (46%) treated with tocilizumab were followed up regularly for 1 month, and 10 cases were effective. Conclusions:Children with sJIA who present with Kawasaki disease-like clinical symptoms have clinical features of Kawasaki disease and sJIA. Children with Kawasaki disease who present at a young age, have a long fever course, are accompanied by joint symptoms, and are IVIG-resistant need to be alert to the possibility of sJIA and receive timely treatment with hormones and biological agents.

Objective:To investigate the impact of the birth of preterm infants on their family functioning, and to provide a reference for the formulation of targeted intervention programs.Methods:Based on the socio ecosystem theory, phenomenological research methods and objective sampling were used to conduct semi-structured interviews with 16 preterm infants in the neonatal intensive care unit (NICU) of Children′s Hospital of Soochow University from September 2023 to January 2024, who meet the inclusion and exclusion criteria, and the Colaizzi 7-step analysis method was used to analyze the interview data.Results:All 16 caregivers of the NICU preterm infants who participated in the interviews were the infants′ mothers, aged from 26 to 34 years. A total of 3 themes and 10 sub-themes were summarized. The micro system: physical and mental exhaustion coexisted with role growth of caregivers (physical and mental health was affected, positive experience after psychological adjustment, and adaptation to role change). The intermediate system: family relationship mode change (family satisfaction decreased, family difficulties affected family harmony, family communication content changed, family harmony and conflict coexisted, and family conflict resolution was actively resolved). The outer system: social support system needed to be improved (benefited from social support and not yet perceived external support).Conclusions:Medical staff can improve the multiple support system and provide continuous and personalized family support, so as to improve the family adjustment ability and improve the family functioning of preterm infants in the NICU.
