Background
Bronchopleural fistula (BPF) is a common and severe complication in thoracic surgery, characterized by its complex nature and high mortality rate. Bronchial occluder is one of the effective methods for the interventional treatment of BPF under bronchoscopy.
Objective
This work was to evaluate the adoption and efficacy of individualized bronchial occluder designed with the assistance of 3D printing technology in the treatment of BPF.
Material and Methods
This single-center, retrospective study included 60 patients (35 males and 25 females, aged 40–78 years, without severe dysfunction of major organs or history of mental disorders) diagnosed with BPF between January 2020 and December 2023, who received different treatment and were divided into the Control Group (CG, receiving thoracotomy treatment), Therapy group-I (TG-I, receiving septal occluder treatment), and Therapy group-II (TG-II, receiving treatment with 3D-printed individualized bronchial occluder). Serum levels of high-sensitivity C-reactive protein (hs-CRP) and procalcitonin (PCT) were measured by enzyme-linked immunosorbent assay preoperatively and at 1, 4, and 12 weeks postoperatively. Daytime cough scores were assessed according to guidelines, pain scores were evaluated using a visual analog scale, clinical efficacy was determined based on consensus criteria, and complications were recorded. Quantitative variables were compared using one-way ANOVA with Bonferroni correction, while categorical variables were analyzed by chi-square or Fisher’s exact test.
Results
the overall clinical efficacy was higher in TG-I and TG-II versus CG, with TG-II showing a greatly higher efficacy after twelve weeks of treatment (P < 0.05). Relative to CG, both TG-I and TG-II demonstrated lower serum levels of hs-CRP and PCT, markedly reduced cough and pain symptom scores, and markedly lower complication rates (P < 0.05). Additionally, TG-II resulted in notably lower serum inflammatory markers, cough and pain symptom scores, and complication rates versus TG-I (P < 0.05).
Conclusion
The 3D-printed personalized occluder (TG-II) significantly reduced postoperative inflammatory responses and alleviated cough-associated pain, demonstrating superior short-term efficacy and safety compared to conventional treatment (CG) and commercially available occluders (TG-I). This approach offers distinct advantages for the personalized precision treatment of BPF. However, further clinical studies are required to validate its potential as an alternative to surgical repair.

Optic disc and cup segmentation is a crucial subfield of computer vision, playing a pivotal role in automated pathological image analysis. It enables precise, efficient, and automated diagnosis of ocular conditions, significantly aiding clinicians in real-world medical applications. However, due to the scarcity of medical segmentation data and the insufficient integration of global contextual information, the segmentation accuracy remains suboptimal. This issue becomes particularly pronounced in optic disc and cup cases with complex anatomical structures and ambiguous boundaries. In order to address these limitations, this paper introduces a self-supervised training strategy integrated with a newly designed network architecture to improve segmentation accuracy. Specifically,we initially propose a non-local dual deformable convolutional block,which aims to capture the irregular image patterns( boundary). Secondly,we modify the traditional vision transformer and design an adaptive K-Nearest Neighbors(KNN) transformation block to extract the global semantic context from images. Finally,an initialization strategy based on self-supervised training is proposed to reduce the burden on the network on labeled data. Comprehensive experimental evaluations demonstrate the effectiveness of our proposed method, which outperforms previous networks and achieves state-of-the-art performance,with IOU scores of 0.9577 for the optic disc and 0.8399 for the optic cup on the REFUGE dataset.

Background: In recent years, nanosilver gel has gained attention due to its excellent antimicrobial properties and wound healing effects. Meanwhile, the comprehensive care model has improved the rehabilitation environment for patients with its holistic and individualized care approach. This study aimed to investigate the promoting effects of nanosilver gel on wound healing in hand injury patients and the intervention effects of the comprehensive care model.
Methods: This study adopted a randomized controlled trial (RCT) design. A total of 120 hand injury patients admitted to the Hand Surgery Department of Beijing Jishuitan Hospital between January 2020 and January 2023 were enrolled and randomly allocated into three groups (n=40 each). The control group (C group) received standard care, experimental group A (Exp A) underwent a comprehensive nursing intervention, and experimental group B (Exp B) received additional nanosilver gel dressing treatment based on the comprehensive nursing protocol. Primary outcome measures included wound healing time, pain intensity (visual analogue scale (VAS) score), functional recovery (grip strength, hand dexterity, and range of motion), and wound healing rate.
Results: Exp group B had notably better outcomes in terms of wound healing time, pain intensity, functional recovery, and wound healing rate versus C group and Exp group A.
Conclusion: This study demonstrates that the combination of nanosilver gel and the comprehensive care model significantly improves wound healing outcomes in hand injury patients, providing a new and effective possibility for the treatment of hand injuries.

Implant-associated infections remain a significant challenge in orthopaedic and dental implants because they frequently result in implant failure, extended hospital stays, reoperations, and increased healthcare costs. Studies have shown that the cost of managing orthopaedic implant infections can range from USD 30,000 to over USD 100,000 per case, depending on severity and required surgical interventions. One of the primary pathogens responsible for these infections is Staphylococcus aureus, known for its potential to make biofilms on the surfaces of implants. To address this problem, this study investigates the formation of calcium phosphate-based biomimetic coatings substituted with calcium-doped ZnO nanoparticles on titanium discs to strengthen the antibacterial properties and enhance tissue integration. The SEM analysis of discs revealed uniform and dense coating layers with negligible surface defects, indicating a strong adhesive coating on titanium discs. The biomimetic-coated titanium implants with Ca-doped ZnO NPs were then evaluated for antibacterial activity using a closed system in an in vitro biofilm model. In case of 14 days treated disc, a significant increase in the antibacterial properties was observed against (Staphylococcus aureus, p < 0.0001). These findings suggest that calcium phosphate-based biomimetic coatings, doped with calcium-doped ZnO NPs show great potential for reducing the risk for implant-associated infections and improving the success rate of implants in clinical settings.
