Background: Three-dimensional (3D) visualization has become increasingly prevalent in orthopedic education to tackle the distinct anatomical challenges of the field. However, there is a conspicuous lack of systematic reviews that thoroughly evaluate both the advantages and drawbacks of integrating 3D with problem-based learning (3D + PBL).
Methods: A rigorous search of English databases (Cochrane Library, Embase, PubMed, Scopus, and Web of Science) and Chinese databases (National Knowledge Infrastructure: CNKI, Chongqing VIP: VIP, and Wan Fang) were performed up to July 2024 to identify relevant studies. Relevant studies were selected based on established eligibility criteria, with clinical data carefully extracted for analysis. Eighteen randomized controlled trials involving a total of 1,077 participants were included in the analysis.
Results: The findings indicated that 3D + PBL instruction significantly outperformed traditional lecture-based learning (LBL) in terms of theoretical knowledge (SMD = 1.62, 95% CI: 1.14-2.10, P < 0.00001) and practical operational scores (SMD = 2.29, 95% CI: 1.41-3.16, P < 0.00001). Furthermore, students exposed to 3D + PBL teaching exhibited a significantly better understanding of orthopedic anatomical structures compared to those receiving LBL (SMD = 1.18, 95% CI: 0.71-1.65, P < 0.00001). Additionally, students in the 3D + PBL group achieved higher theoretical grades (OR = 2.95, 95% CI: 1.57-5.55, P = 0.0008) and reported greater overall satisfaction (OR = 3.26, 95% CI: 1.91-5.54, P < 0.0001) compared to their LBL counterparts.
Conclusion: Given the unique demands of orthopedic education, 3D + PBL emerges as a highly effective teaching method. It not only improves students' theoretical scores but also enhances their communication skills and comprehension of complex concepts. Furthermore, students exhibit greater satisfaction with this approach.

Automatic segmentation of angiographic structures can aid in assessing vascular disease. While recent deep learning models promise automation, they lack validation on interventional angiographic data. This study investigates the feasibility of angiographic segmentation using in-context learning with the UniverSeg model, which is a cross-learning segmentation model that lacks inherent angiographic training.

Aspect Category Sentiment Analysis (ACSA) is a fine-grained sentiment analysis task aimed at predicting the sentiment polarity associated with aspect categories within a sentence.Most existing ACSA methods are based on a given aspect category to locate sentiment words related to it. When irrelevant sentiment words have semantic meaning for the given aspect category, it may cause the problem that sentiment words cannot be matched with aspect categories.

The problem of ground-level ozone (O) pollution has become a global environmental challenge with far-reaching impacts on public health and ecosystems. Effective control of ozone pollution still faces complex challenges from factors such as complex precursor interactions, variable meteorological conditions and atmospheric chemical processes. To address this problem, a convolutional neural network (CNN) model combining the improved particle swarm optimization (IPSO) algorithm and SHAP analysis, called SHAP-IPSO-CNN, is developed in this study, aiming to reveal the key factors affecting ground-level ozone pollution and their interaction mechanisms.

Predicting the 3D structure of RNA is a significant challenge despite ongoing advancements in the field. Although AlphaFold has successfully addressed this problem for proteins, RNA structure prediction raises difficulties due to the fundamental differences between proteins and RNA, which hinder its direct adaptation. The latest release of AlphaFold, AlphaFold3, has broadened its scope to include multiple different molecules such as DNA, ligands and RNA.
