OBJECTIVE: To investigate the surgical technique and preliminary effectiveness of closed reduction and internal fixation (CRIF) using antegrade elastic intramedullary nailing (ESIN) via a novel approach through the proximal radius for treating distal radius metaphyseal-diaphyseal junction (DRMDJ) fractures in children. METHODS: A retrospective analysis was conducted on 34 children with DRMDJ fractures who met the selection criteria and were treated between January 2020 and June 2023. There were 21 boys and 13 girls, aged 6-14 years (mean, 8.2 years). Injury causes included falls in 11 cases and sports-related trauma in 23 cases. Twenty-six cases were associated with ipsilateral distal ulnar fractures. All patients had failed initial closed reduction in the outpatient clinic. The time from injury to operation ranged from 1 to 15 days (mean, 4 days). All patients underwent CRIF using antegrade ESIN inserted via a novel approach at the proximal one-third of the radius. The operation time, intraoperative fluoroscopy frequency, fracture healing time, and complications were recorded. Fracture reduction was assessed immediately after operation on anteroposterior and lateral X-ray films for residual translation and angulation. Wrist function was evaluated using the modified Mayo wrist score. RESULTS: Surgery was successfully completed in all 34 children. CRIF with ESIN failed in 2 cases with associated ipsilateral distal ulnar fractures, requiring conversion to open reduction of the ulna. Operation time ranged from 15 to 56 minutes (mean, 21 minutes). Intraoperative fluoroscopy frequency ranged from 5 to 21 times (mean, 7 times). Immediate postoperative X-ray films showed residual translation of 0-15% on anteroposterior view and 0-10% on lateral view, and residual angulation of 0°-5° on both anteroposterior and lateral views. All children were followed up 6-18 months (mean, 12 months). There was no complication such as neurovascular injury, incision infection, or limitation of forearm rotation. Follow-up X-ray films showed no fracture displacement, implant loosening, delayed union, or nonunion. Fracture healing time ranged from 4 to 8 weeks (mean, 6 weeks). Implants were removed at 4-6 months postoperatively (mean, 5 months). At last follow-up, all fractures had achieved anatomic or near-anatomic healing. The modified Mayo wrist score ranged from 80 to 100 (mean, 94), with 27 excellent and 7 good results, yielding an excellent and good rate of 100%. CONCLUSION CRIF using antegrade ESIN via a novel approach through proximal radius is a safe and effective treatment for pediatric DRMDJ fractures, associated with few postoperative complications and excellent restoration of wrist function.

Objective:To build an internet hospital cost-benefit evaluation index system based on a large public tertiary hospital, for references for improving the operation and management of internet hospitals.Methods:From May to October 2024, this study identified the elements of cost-benefit through on-site investigation, literature analysis and expert discussion, and built an initial evaluation index system of cost-benefit of internet hospitals; Delphi method and Pareto chart method were used to determine indicators and their weights; This evaluation index system was used to quantitatively evaluate an internet hospital since its operation for two years (from May 2022 to April 2024).Results:Five profit entities and 26 cost-benefit components had been identified; The expert authority coefficient of the two rounds of Delphi method was 0.73, and the Kendall coefficient was 0.80 ( P<0.001). The costs and benefits of an internet hospital since its operation for two years were 14.06 million yuan and 134.95 million yuan, respectively, with a benefit cost ratio of 9.60. Conclusions:The cost-benefit evaluation index system of internet hospitals built in this study was suitable for these relying on physical hospitals. This system was scientific and practical, and could provide references for cost-benefit evaluation of other Internet hospitals.

Elderly stroke patients generally have restricted life space,which increases the incidence of falls,weakness,and dementia,reduces their quality of life,and ultimately leads to an increase in readmission and mortality rates.This article mainly introduces the concept,theoretical model and measuring tools of life space.The level and influencing factors of life space in elderly stroke patients were reviewed in order to provide references for medical staff to carry out relevant research and formulate targeted intervention programs about life space for elderly stroke patients.

This case report summarizes the experience from diagnosis and treatment of a patient with repeated high fever, hepatosplenomegaly and pancytopenia. Following exclusion of bacterial, viral, fungal infections and hematological diseases, metagenomic next-generation sequencing of the patient’s peripheral blood revealed Leishmania infantum infection, and rK39 rapid diagnostic test showed positive for anti-Leishmania antibody, while microscopic examination of bone marrow smears identified Leishmania amastigotes. Therefore, the case was definitively diagnosed as visceral leishmaniasis, and given anti-infective treatment with sodium antimony gluconate and hormone, hepatoprotection, elevation of white blood cell counts and personalized nursing. Then, the case was cured and discharged from hospital. Metagenomic next-generation sequencing is of great value in etiological detection of fever patients with unknown causes, which deserves widespread clinical applications.
