Based on the theory of "sweet-flavored medicinals retaining and restoring body fluid"， this paper proposed that the core pathogenesis of hypercoagulable state in malignant tumors is qi deficiency and fluid consumption， blood stasis and vessels stagnation， which evolves dynamically according to the pattern "qi deficiency → fluid consumption → blood stasis". Accordingly， a staged treatment system is established with the general principle of "fortifying the middle jiao， restoring fluid and activating blood circulation". In the initial stage， invigorating the spleen and boosting qi to generate body fluid， targeting the onset of middle jiao deficiency and body fluid consumption； in the middle stage， nourishing yin and unblocking collaterals to facilitate body fluid circulation， addressing the disorder of body fluid transportation and collateral injury caused by internal dryness； in the late stage， consolidating yin and resolving blood stasis to retain body fluid， resolving yin impairment， fluid exhaustion， and binding of stasis and toxin. By regulating body fluid metabolism to improve the hypercoagulable state， this system is intended to provide insights for the prevention and treatment of hypercoagulable state in malignant tumors with traditional Chinese medicine.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

The rich club, as a community of highly interconnected nodes, serves as the topological center of the network. However, the similarities and differences in how the rich club supports functional integration and segregation in the brain across different species remain unknown. In this study, we first detected and validated the rich club in the structural networks of mouse, monkey, and human brains using neuronal tracing or diffusion magnetic resonance imaging data. Further, we assessed the role of rich clubs in functional integration, segregation, and balance using quantitative metrics. Our results indicate that the presence of a rich club facilitates whole-brain functional integration in all three species, with the functional networks of higher species exhibiting greater integration. These findings are expected to help to understand the relationship between brain structure and function from the perspective of brain evolution.

Objective:To investigate the efficacy and complications of ventriculoperitoneal shunt (VPS) and endoscopic third ventriculostomy (ETV) in the treatment of hydrocephalus in children.Methods:This study was a retrospective analysis. A total of 120 children with hydrocephalus admitted to Xi'an Children's Hospital from January 2021 to March 2024 were selected. Among them, 49 children who underwent VPS treatment were included in the VPS group, and 71 children who underwent ETV treatment were included in the ETV group. Perioperative indicators, complication rates, postoperative recovery outcomes, levels of neurological injury markers, and developmental status at 6 months postoperatively were compared between the two groups. Measurement data with normal distribution were expressed as Mean ± SD, and intergroup comparisons was performed by independent samples t-test; counting data were expressed as case (%), and intergroup comparisons were performed by χ2 test. Results:The operation time [(83.26±10.67) min], time to first flatus [(2.58±0.44) days], and total complication rate [24.49% (12/49)] in the VPS group were all higher than those in the ETV group [(74.68±8.64) min, (2.21±0.42) days, and 9.86% (7/71)], while the one-time success rate [81.63% (40/49)] was lower than that in the ETV group [95.77% (68/71)]. The differences between the groups were statistically significant ( t=4.85, P<0.001; t=4.65, P<0.001; χ2=4.66, P=0.031; χ2=4.97, P=0.026, respectively). On postoperative day 3, the Glasgow Coma Scale score in the VPS group [(12.46±0.72) points] was lower than that in the ETV group [(12.89±0.67) points], and on postoperative day 7, the National Institutes of Health Stroke Scale score in the VPS group [(8.96±1.09) points] was higher than that in the ETV group [(8.54±1.02) points], with statistically significant differences ( t=3.35, P=0.001; t=2.16, P=0.033, respectively). On postoperative day 3, the levels of central nervous system-specific protein [(12.57±2.51) mg/L], high mobility group box 1 protein [(28.83±3.77) μg/L], and neuron-specific enolase [(21.47±2.56) μg/L] in the VPS group were all higher than those in the ETV group [(10.54±2.11) mg/L, (25.63±3.26) μg/L, (19.27±2.31) μg/L], and the differences were statistically significant ( t=5.04, P<0.001; t=4.96, P<0.001; t=4.91, P<0.001, respectively). At 6 months postoperatively, the developmental quotient score in the VPS group [(84.15±3.14) points] was lower than that in the ETV group [(86.51±3.27) points], and the difference was statistically significant ( t=3.93, P<0.001). Conclusion:Both VPS and ETV can be used for the treatment of hydrocephalus in children. However, ETV has a higher one-time success rate, better perioperative indicators, fewer complications, and superior postoperative neurological recovery compared to VPS.

Bone organoids can simulate the complex structure and function of the bone tissues, which makes them a frontier technology in organoid researches. Bone organoids show a tremendous potential of applications in bone disease modeling, bone injury repair, and medicine screening. Although advancements have been made so far in constructing bone organoids with functional structures like mineralization, bone marrow, trabecular bone, callus, woven bone, etc, the researches in this field are confronted with numerous challenges such as lack of standardized construction strategies and unified evaluation criteria, which limits their further promotion and application. To standardize researches in bone organoids, the Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, the Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, the Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and the Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine organized related experts to formulate Expert consensus on the construction, evaluation, and application of bone organoids ( version 2024) based on an evidence-based approach. A total of 17 recommendations were put forth, aiming to standardize researches and clinical applications of bone organoids and enhance their value in scientific research and clinical practice.

OBJECTIVE: To investigate the consistency and diagnostic performance of magnetic resonance imaging (MRI) for detecting microvascular invasion (MVI) of hepatocellular carcinoma (HCC) and the validity of deep learning attention mechanisms and clinical features for MVI grade prediction. METHODS: This retrospective study was conducted among 158 patients with HCC treated in Shunde Hospital Affiliated to Southern Medical University between January, 2017 and February, 2020. The imaging data and clinical data of the patients were collected to establish single sequence deep learning models and fusion models based on the EfficientNetB0 and attention modules. The imaging data included conventional MRI sequences (T₁WI, T₂WI, and DWI), enhanced MRI sequences (AP, PP, EP, and HBP) and synthesized MRI sequences (T1mapping-pre and T1mapping-20 min), and the high-risk areas of MVI were visualized using deep learning visualization techniques. RESULTS: The fusion model based on T1mapping-20min sequence and clinical features outperformed other fusion models with an accuracy of 0.8376, a sensitivity of 0.8378, a specificity of 0.8702, and an AUC of 0.8501 for detecting MVI. The deep fusion models were also capable of displaying the high-risk areas of MVI. CONCLUSION The fusion models based on multiple MRI sequences can effectively detect MVI in patients with HCC, demonstrating the validity of deep learning algorithm that combines attention mechanism and clinical features for MVI grade prediction.

Type 2 diabetes (T2D) is characterized by the malfunction of pancreatic β cells. Susceptibility and pathogenesis of T2D can be affected by multiple factors, including sex differences. However, the mechanisms underlying sex differences in T2D susceptibility and pathogenesis remain unclear. Using single-cell RNA sequencing (scRNA-seq), we demonstrate the presence of sexually dimorphic transcriptomes in mouse β cells. Using a high-fat diet-induced T2D mouse model, we identified sex-dependent T2D altered genes, suggesting sex-based differences in the pathological mechanisms of T2D. Furthermore, based on islet transplantation experiments, we found that compared to mice with sex-matched islet transplants, sex-mismatched islet transplants in healthy mice showed down-regulation of genes involved in the longevity regulating pathway of β cells. Moreover, the diabetic mice with sex-mismatched islet transplants showed impaired glucose tolerance. These data suggest sexual dimorphism in T2D pathogenicity, indicating that sex should be considered when treating T2D. We hope that our findings could provide new insights for the development of precision medicine in T2D.
