Abstract :

The development of BACE-1 (beta-site amyloid precursor protein cleaving enzyme 1) inhibitors is a crucial focus in exploring early treatments for Alzheimer's disease (AD). Recently, graph neural networks (GNNs) have demonstrated significant advantages in predicting molecular activity. However, their reliance on graph structures alone often neglects explicit sequence-level semantic information. To address this limitation, we proposed a Graph and multi-level Sequence Fusion Learning (GSFL) model for predicting the molecular activity of BACE-1 inhibitors. Firstly, molecular graph structures generated from SMILES strings were encoded using GNNs with an atomic-level characteristic attention mechanism. Next, substrings at functional group, ion level, and atomic level substrings were extracted from SMILES strings and encoded using a BiLSTM-Transformer framework equipped with a hierarchical attention mechanism. Finally, these features were fused to predict the activity of BACE-1 inhibitors. A dataset of 1548 compounds with BACE-1 activity measurements was curated from the ChEMBL database. In the classification experiment, the model achieved an accuracy of 0.941 on the training set and 0.877 on the test set. For the test set, it delivered a sensitivity of 0.852, a specificity of 0.894, a MCC of 0.744, an F1-score of 0.872, a PRC of 0.869, and an AUC of 0.915. Compared to traditional computer-aided drug design methods and other machine learning algorithms, the proposed model can effectively improve the accuracy of the molecular activity prediction of BACE-1 inhibitors and has a potential application value.

Abstract :

BACKGROUND The degree of obstruction plays an important role in decision-making for obstructive colorectal cancer (OCRC). The existing assessment still relies on the colorectal obstruction scoring system (CROSS) which is based on a comprehensive analysis of patients' complaints and eating conditions. The data collection relies on subjective descriptions and lacks objective parameters. Therefore, a scoring system for the evaluation of computed tomography-based obstructive degree (CTOD) is urgently required for OCRC. AIM To explore the relationship between CTOD and CROSS and to determine whether CTOD could affect the short-term and long-term prognosis. METHODS Of 173 patients were enrolled. CTOD was obtained using k-means, the ratio of proximal to distal obstruction, and the proportion of nonparenchymal areas at the site of obstruction. CTOD was integrated with the CROSS to analyze the effect of emergency intervention on complications. Short-term and long-term outcomes were compared between the groups. RESULTS CTOD severe obstruction (CTOD grade 3) was an independent risk factor [odds ratio (OR) = 3.390, 95% confidence interval (CI): 1.340-8.570, P = 0.010] via multivariate analysis of short-term outcomes, while CROSS grade was not. In the CTOD-CROSS grade system, for the non-severe obstructive (CTOD 1-2 to CROSS 1-4) group, the complication rate of emergency interventions was significantly higher than that of non-emergency interventions (71.4% vs 41.8%, P = 0.040). The postoperative pneumonia rate was higher in the emergency intervention group than in the non-severe obstructive group (35.7% vs 8.9%, P = 0.020). However, CTOD grade was not an independent risk factor of overall survival and progression-free survival. CONCLUSION CTOD was useful in preoperative decision-making to avoid unnecessary emergency interventions and complications.

Abstract :

Atrial fibrillation (AF) is a prevalent heart rate arrhythmia and its incidence is increasing with the aging population. The late gadoliniumenhanced magnetic resonance imaging (LGE-MRI) provides pathologic changes in the left atrium, allowing for a detailed assessment of the left atrial anatomy, which is critical for diagnosis and treatment decisions in AF. The segmentation performance of current left atrial segmentation methods is significantly degraded when applied to multicenter data. In this work, we propose ResCAUNet, a deep learning method based on residual neural networks. Specifically, a pre-trained model driven residual segmentation network is first designed to alleviate the problem of gradient disappearance and help to extract more complex image features. Secondly, an adaptive scale weight loss function was introduced to solve the problem of discontinuous segmentation boundary, so as to ensure higher accuracy of object segmentation. Furthermore, the coordinate attention(CA) mechanism is introduced for adaptive weight allocation, focusing on the key parts of the image to improve the accuracy of left atrial reconstruction. Our method is evaluated on the LAScarQS2024 validation set and achieves an average Dice of 0.853. The evaluation results show that the proposed method is effective in left atrium segmentation of LGE-MRI. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Abstract :

Cardiac scarring and edema are critical pathological features of heart diseases. Accurate segmentation of these features in Cardiac Magnetic Resonance (CMR) imaging is crucial for understanding the pathological changes associated with cardiac diseases. In the field of myocardial scar and edema segmentation, it is of significant importance to study the C0, T2, and LGE modalities. These modalities offer different perspectives on myocardial tissue characteristics, aiding in the more accurate diagnosis and assessment of cardiac diseases. However, the high-intensity features of scars and edema cannot be directly obtained from individual CMR imaging sequences, making simultaneous accurate segmentation challenging. To address this, we propose a multi-modal, multi-channel fusion interactive progressive segmentation strategy that leverages the distinctive properties of each modality and the surrounding tissue characteristics for the segmentation of myocardial scars and edema. We have designed a multi-channel fusion interactive progressive segmentation model, suitable for scar and myocardial segmentation, which incorporates an attention mechanism that enhances channel information interaction within a U-Net structure to extract features across different modalities. On the MyoPS++ 2024 public dataset, our method achieved an average Dice score of 0.5486 for scar segmentation and 0.6081 for the segmentation of both scars and edema. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Dual-phase airway segmentation: Enhancing distal bronchial identification with anatomical prior guidance SCIE
期刊论文 | 2025 , 153 | ENGINEERING APPLICATIONS OF ARTIFICIAL INTELLIGENCE
Abstract&Keyword Cite Version(2)

Abstract :

Airway segmentation and reconstruction are critical for preoperative lesion localization and surgical planning in pulmonary interventions. However, this task remains challenging due to the intrinsically complex tree structure of the airway and the imbalance in branch sizes. While current deep learning methods focus on model architecture optimization, they underutilize anatomical priors such as the spatial correlation between pulmonary arteries and bronchi beyond geometric grading level III. To address this limitation, we propose dual-decoding segmentation network (DDS-Net) integrated with a pulmonary-bronchial extension generative adversarial network (PBE-GAN), which explicitly embeds artery-bronchus adjacency priors to enhance distal bronchial identification. Experimental results demonstrate state-of-the-art performance, achieving a Dice Similarity Coefficient (DSC) of 88.46%, Branch Detection Rate (BD) of 88.31%, and Tree Length Detection Rate (TD) of 84.93%, with significant improvements in detecting peripheral bronchi near pulmonary arteries. This study confirms that incorporating anatomical relationships substantially improves segmentation accuracy, particularly for fine structures. Future work should prioritize clinical validation through multi-center trials and explore integration with real-time surgical navigation systems, while extending similar anatomical synergy principles to other organ-specific segmentation tasks.

Abstract :

Background: Automatic pulmonary artery-vein separation has considerable importance in the diagnosis and treatment of lung diseases. However, insufficient connectivity and spatial inconsistency have always been the problems of artery-vein separation. Methods: A novel automatic method for artery-vein separation in CT images is presented in this work. Specifically, a multi-scale information aggregated network (MSIA-Net) including multi-scale fusion blocks and deep supervision, is proposed to learn the features of artery-vein and aggregate additional semantic information, respectively. The proposed method integrates nine MSIA-Net models for artery-vein separation, vessel segmentation, and centerline separation tasks along with axial, coronal, and sagittal multi-view slices. First, the preliminary artery-vein separation results are obtained by the proposed multi-view fusion strategy (MVFS). Then, centerline correction algorithm (CCA) is used to correct the preliminary results of artery- vein separation by the centerline separation results. Finally, the vessel segmentation results are utilized to reconstruct the artery-vein morphology. In addition, weighted cross-entropy and dice loss are employed to solve the class imbalance problem. Results: We constructed 50 manually labeled contrast-enhanced computed CT scans for five-fold cross -validation, and experimental results demonstrated that our method achieves superior segmentation perfor-mance of 97.7%, 85.1%, and 84.9% on ACC, Pre, and DSC, respectively. Additionally, a series of ablation studies demonstrate the effectiveness of the proposed components. Conclusion: The proposed method can effectively solve the problem of insufficient vascular connectivity and correct the spatial inconsistency of artery-vein.

Abstract :

Purpose: The identification of early-stage Parkinson's disease (PD) is important for the effective management of patients, affecting their treatment and prognosis. Recently, structural brain networks (SBNs) have been used to diagnose PD. However, how to mine abnormal patterns from high-dimensional SBNs has been a challenge due to the complex topology of the brain. Meanwhile, the existing prediction mechanisms of deep learning models are often complicated, and it is difficult to extract effective interpretations. In addition, most works only focus on the classification of imaging and ignore clinical scores in practical applications, which limits the ability of the model. Inspired by the regional modularity of SBNs, we adopted graph learning from the perspective of node clustering to construct an interpretable framework for PD classification.Methods: In this study, a multi-task graph structure learning framework based on node clustering (MNC-Net) is proposed for the early diagnosis of PD. Specifically, we modeled complex SBNs into modular graphs that facilitated the representation learning of abnormal patterns. Traditional graph neural networks are optimized through graph structure learning based on node clustering, which identifies potentially abnormal brain regions and reduces the impact of irrelevant noise. Furthermore, we employed a regression task to link clinical scores to disease classification, and incorporated latent domain information into model training through multi-task learning.Results: We validated the proposed approach on the Parkinsons Progression Markers Initiative dataset. Exper-imental results showed that our MNC-Net effectively separated the early-stage PD from healthy controls(HC) with an accuracy of 95.5%. The t-SNE figures have showed that our graph structure learning method can capture more efficient and discriminatory features. Furthermore, node clustering parameters were used as important weights to extract salient task-related brain regions(ROIs). These ROIs are involved in the development of mood disorders, tremors, imbalances and other symptoms, highlighting the importance of memory, language and mild motor function in early PD. In addition, statistical results from clinical scores confirmed that our model could capture abnormal connectivity that was significantly different between PD and HC. These results are consistent with previous studies, demonstrating the interpretability of our methods.

Abstract :

Background: With the wide application of CT scanning, the separation of pulmonary arteries and veins (A/V) based on CT images plays an important role for assisting surgeons in preoperative planning of lung cancer surgery. However, distinguishing between arteries and veins in chest CT images remains challenging due to the complex structure and the presence of their similarities. Methods: We proposed a novel method for automatically separating pulmonary arteries and veins based on vessel topology information and a twin-pipe deep learning network. First, vessel tree topology is constructed by combining scale-space particles and multi-stencils fast marching (MSFM) methods to ensure the continuity and authenticity of the topology. Second, a twin-pipe network is designed to learn the multiscale differences between arteries and veins and the characteristics of the small arteries that closely accompany bronchi. Finally, we designed a topology optimizer that considers interbranch and intrabranch topological relationships to optimize the results of arteries and veins classification. Results: The proposed approach is validated on the public dataset CARVE14 and our private dataset. Compared with ground truth, the proposed method achieves an average accuracy of 90.1% on the CARVE14 dataset, and 96.2% on our local dataset. Conclusions: The method can effectively separate pulmonary arteries and veins and has good generalization for chest CT images from different devices, as well as enhanced and noncontrast CT image sequences from the same device.

Abstract :

Objectives Patients with T4 obstructive colorectal cancer (OCC) have a high mortality rate. Therefore, an accurate distinction between T4 and T1-T3 (NT4) in OCC is an important part of preoperative evaluation, especially in the emergency setting. This paper introduces three models of radiomics, deep learning, and deep learning-based radiomics to identify T4 OCC.Methods We established a dataset of computed tomography (CT) images of 164 patients with pathologically confirmed OCC, from which 2537 slides were extracted. First, since T4 tumors penetrate the bowel wall and involve adjacent organs, we explored whether the peritumoral region contributes to the assessment of T4 OCC. Furthermore, we visualized the radiomics and deep learning features using the t-distributed stochastic neighbor embedding technique (t-SNE). Finally, we built a merged model by fusing radiomic features with deep learning features. In this experiment, the performance of each model was evaluated by the area under the receiver operating characteristic curve (AUC).Results In the test cohort, the AUC values predicted by the radiomics model in the dilated region of interest (dROI) was 0.770. And the AUC value of the deep learning model with the patches extended 20-pixel reached 0.936. Combining the characteristics of radiomics and deep learning, our method achieved an AUC value of 0.947 in the T4 and non-T4 (NT4) classification, and increased the AUC value to 0.950 after the addition of clinical features.Conclusion The prediction results of our merged model of deep learning radiomics outperformed the deep learning model and significantly outperformed the radiomics model. The experimental results demonstrate that combining the peritumoral region improves the prediction performance of the radiomics model and the deep learning model.
