OBJECTIVE To construct ensemble learning models for predicting high-use days of budesonide based on meteorological factors， thereby providing reference for hospital pharmacy management. METHODS Meteorological data for 2024 and outpatient budesonide usage data from the jurisdiction of Sanming Hospital of Integrated Traditional Chinese and Western Medicine were collected. High-use days were defined as the 75th percentile of outpatient budesonide usage， and a corresponding dataset was established. The prediction task was formulated as a classification problem， and three ensemble learning models were developed： Random Forest， Extreme Gradient Boosting （XGBoost）， and Histogram-based Gradient Boosting Classifier. Model performance was evaluated using accuracy， precision， recall， F1-score， and log-loss. Model interpretability was analyzed using Shapley Additive Explanations （SHAP）. RESULTS The Histogram-based Gradient Boosting Classifier achieved the best performance （accuracy＝0.75， F1-score＝0.48）， followed by XGBoost （accuracy＝0.74， F1-score＝0.43） and Random Forest （accuracy＝0.72， F1-score＝0.22）. SHAP results suggested that the prediction results of the last two models have the highest correction. CONCLUSIONS Ensemble learning models can effectively predict high-use days of budesonide， with the Histogram- based Gradient Boosting Classifier demonstrating the best predictive performance. Low temperature， high humidity， and low atmospheric pressure show significant positive impacts on the prediction of daily budesonide usage.

Objective:To compare the mid-term efficacy of one anastomosis gastric bypass (OAGB) and sleeve gastrectomy (SG) in the treatment of obesity and metabolic syndrome, and related postoperative complications.Method:Clinical data of patients undergoing indirect OAGB or SG from Jan to Dec 2022 was enrolled. Firty-eight patients were included in the OAGB group and 178 patients were included in the SG group. Propensity matching scores was performed with matching ratio of 1∶1. Eighty-four patients (42 in each group) were included in the analysis finally. We compared the differences in weight loss, metabolic syndrome remission, and postoperative complications among different groups.Result:The 2-year follow-up results show that the OAGB group and SG group showed similar improvements in weight, BMI, percentage of total weight loss, percentage of excess weight loss [(71.60±11.47)kg vs. (72.90±11.21)kg, t=0.529, P>0.05;(26.13±4.16)kg/m 2vs. (26.86±4.12)kg/m 2, t=0.805, P>0.05; (30.89%±9.68%) vs. (27.59%±7.74%), t=1.726, P>0.05; (99.25%± 36.35%) vs. (97.02%±40.97%), t=0.264, P>0.05]. In terms of metabolic complications, the OAGB group had a higher remission rate. The OAGB group showed more significant improvements in fasting plasma glucose, glycated Hemoglobin A1c, triglycerides, uric acid [(5.11±0.36)mmol/L vs. (5.40±0.63)mmol/L, t=2.593, P<0.05; (5.13%±0.4%) vs. (5.38%±0.36%), t=2.889, P<0.05; (0.94±0.35)mmol/L vs. (1.12±0.41)mmol/L, t=2.145, P<0.05; (330.60±73.73)μmol/L vs. (394.30±111.43)μmol/L, t=3.089, P<0.05]. There was no statistically significant difference in hemoglobin and albumin, but the serum iron in the OAGB group was lower than SG group, and the difference was statistically significant [(14.45±7.75)μmol/L vs.(17.78±6.58)μmol/L, t=2.118, P<0.05]. There was no difference between the two groups in terms of postoperative complications. Conclusion:OAGB has similar weight loss effects and postoperative complication rates compared to SG, and effectively improves metabolic symptoms.

In recent years, with the rapid development of artificial intelligence technology, the application of deep learning in the field of pathology has been continuously expanding. Particularly, the rise of multimodal data fusion methods has opened up new technical paths for the precise diagnosis, prognosis assessment, and individualized treatment of tumors. By integrating multi-level and multi-source data such as clinical information, pathological omics, molecular omics, and imaging omics, deep learning models can identify potential associated features and key biological mechanisms that are difficult to reveal by a single modality, thereby significantly improving the accuracy of disease classification and the scientific nature of risk stratification. This article systematically reviews the research progress of multimodal data fusion methods based on deep learning in the field of pathology in recent years, focuses on sorting out different types of fusion strategies, evaluates their advantages and challenges in practical clinical applications, and looks forward to future development trends.

For middle-aged and elderly patients with conditions such as spinal fractures and degenerative spinal diseases, spinal internal fixation is a core surgical procedure for reconstructing spinal stability, heavily relying on the biomechanical stability provided by pedicle screw systems. Whereas, these patients are often complicated by osteoporosis that can significantly compromise the stability of the bone-pedicle screw interface, leading to a marked increase in pedicle screw loosening and surgical failure rates. The bone cement-augmented pedicle screw technique, which involves injecting bone cement into the vertebral body or screw trajectory to optimize the mechanical properties of the bone-pedicle screw composite, has been proven to significantly enhance fixation strength and effectively prevent screw-related failures, thereby reducing the incidence of internal fixation failure in high-risk populations undergoing spinal fusion. However, the widespread clinical application of this technique has faced challenges such as inaccurate clinical decision-making (indication and contraindication selection), non-standardized operative practices, and insufficient awareness of complication prevention, resulting in considerable variability in clinical outcomes and even severe complications. To address this, Prof. Luo Fei from First Affiliated Hospital of Army Medical University initiated the project and the Chinese Association Orthopaedic Surgeons organized relevant experts to develop the Evidence-based clinical practice guideline for bone cement-augmented pedicle screw technique ( version 2025), based on current evidence. The guidelines put forward 8 recommendations regarding the clinical value, scope of application, and operational standards of the technique, aiming to provide evidence-based medical support and technical standardization for clinical decision-making.

Objective:To investigate the effect of Lulongzaisheng decoction on ferroptosis in aplastic anemia (AA) model mice and its potential mechanism of action on AA.Methods:Using female BALB/c mice as controls (control group), a mouse model of AA was established by intraperitoneal injection of interferon-γ (IFN-γ) combined with oral gavage of busulfan. The AA group was treated with continuous oral gavage of Lulongzaisheng decoction for 10 days. The effects on the Jak2/Stat3/Acsl4 signaling pathway were assessed. Bone marrow biopsy and histopathological examination were performed to observe the degree of AA in each group of mice. Flow cytometry was used to detect the production of lipid reactive oxygen species (ROS) in the bone marrow cells. Immunohistochemical staining was performed to observe the expression of 4-HNE in the sternum. Western blot analysis was conducted to determine the protein expression levels of Jak2, p-Jak2, Stat3, p-Stat3, and Acsl4. ELISA was used to measure the levels of interleukin-6 (IL-6) in the peripheral blood plasma.Results:Compared with the control group, mice in the AA group exhibited a reduction in hematopoietic tissues within the bone marrow cavity and significant fatty infiltration. In contrast, mice in the AA+Lulongzaisheng decoction group showed partial recovery of the bone marrow and a decrease in fatty infiltration. The lipid ROS proportions in the control, AA, and AA+Lulongzaisheng decoction groups were (47.01±3.07) %, (53.81±1.99) %, and (49.50±3.98) %, respectively ( P<0.05), indicating that the AA + Lulongzaisheng decoction group had a slightly lower accumulation of lipid ROS than the AA group. The expression areas of 4-HNE in the bone marrow cavity for the control, AA, and AA+Lulongzaisheng decoction groups were (6.34±1.07) %, (35.26±3.68) %, and (16.97±1.30) %, respectively ( P<0.05), demonstrating a significant reduction in 4-HNE accumulation in the bone marrow in the AA + Lulongzaisheng decoction group compared with that in the AA group. Compared with the control group, the AA group exhibited upregulated expression of the ferroptosis-related protein Acsl4, along with increased expression of p-Stat3 and p-Jak2. In the AA+ Lulongzaisheng decoction group, the expression of Acsl4 was downregulated, whereas those of p-Stat3 and p-Jak2 were inhibited ( P<0.05). The levels of IL-6 in the peripheral blood plasma were (65.60±6.01), (166.50±3.32), and (119.37±4.29) pg/ml in the control, AA, and AA+Lulongzaisheng decoction groups, respectively ( P<0.05). Compared with the AA group, the AA + Lulongzaisheng decoction group exhibited a significant decrease in IL-6 levels. Conclusion:This study shows that Lulongzaisheng decoction has a significant therapeutic effect on AA model mice by regulating the Jak2/Stat3/Acsl4 pathway. The mechanism of action of this traditional Chinese medicine involves inhibiting the Jak2/Stat3 signaling pathway and regulating the expression of Acsl4, thereby improving hematopoietic function in AA model mice. These findings provide new drug targets and treatment strategies for the treatment of AA.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

ObjectiveTo investigate the effect of high-definition transcranial direct current stimulation (HD-tDCS) combined with upper limb robot on upper limb dysfunction in patients with ischemic stroke. MethodsFrom January, 2023 to March, 2024, 56 inpatients with upper limb dysfunction after ischemic stroke were selected from Zhejiang Rehabilitation Medical Center, and divided into control group (n = 28) and experimental group (n = 28) randomly. All the patients received comprehensive treatment and upper limb robot training, while the control group received sham HD-tDCS and the experimental group received HD-tDCS, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Wolf Motor Function Test (WMFT) and modified Barthel Index (MBI) before and after treatment. The cortical amplitude, cortical latency and central motor conduction time (CMCT) of transcranial magnetic stimulation motor-evoked potential (MEP) were recorded, and a correlation analysis was conducted. ResultsThe scores of FMA-UE, WMFT and MBI, and MEP cortical amplitude, cortical latency and CMCT improved in both groups after treatment (t > 3.177, P < 0.01), and they were better in the experimental group than in the control group (t > 3.610, P < 0.01). The scores of FMA-UE and WMFT negatively correlated with MEP cortical latency and CMCT, and positively correlated with MEP cortical amplitude (|r| > 0.448, P < 0.001). ConclusionHD-tDCS is effective on upper limb motor function and activities of daily living for patients with ischemic stroke, and can improve corticospinal motor conduction.

BACKGROUND: The main cause of restenosis after percutaneous transluminal angioplasty (PTA) is the excessive proliferation and migration of vascular smooth muscle cells (VSMCs). Lin28a has been reported to play critical regulatory roles in this process. However, whether CCAAT/enhancer-binding proteins β (C/EBPβ) binds to the Lin28a promoter and drives the progression of restenosis has not been clarified. Therefore, in the present study, we aim to clarify the role of C/EBPβ-Lin28a axis in restenosis. METHODS: Restenosis and atherosclerosis rat models of type 2 diabetes ( n   =  20, for each group) were established by subjecting to PTA. Subsequently, the difference in DNA methylation status and expression of C/EBPβ between the two groups were assessed. EdU, Transwell, and rescue assays were performed to assess the effect of C/EBPβ on the proliferation and migration of VSMCs. DNA methylation status was further assessed using Methyltarget sequencing. The interaction between Lin28a and ten-eleven translocation 1 (TET1) was analysed using co-immunoprecipitation (Co-IP) assay. Student's t -test and one-way analysis of variance were used for statistical analysis. RESULTS: C/EBPβ expression was upregulated and accompanied by hypomethylation of its promoter in restenosis when compared with atherosclerosis. In vitroC/EBPβ overexpression facilitated the proliferation and migration of VSMCs and was associated with increased Lin28a expression. Conversely, C/EBPβ knockdown resulted in the opposite effects. Chromatin immunoprecipitation assays further demonstrated that C/EBPβ could directly bind to Lin28a promoter. Increased C/EBPβ expression and enhanced proliferation and migration of VSMCs were observed after decitabine treatment. Further, mechanical stretch promoted C/EBPβ and Lin28a expression accompanied by C/EBPβ hypomethylation. Additionally, Lin28a overexpression reduced C/EBPβ methylation via recruiting TET1 and enhanced C/EBPβ-mediated proliferation and migration of VSMCs. The opposite was noted in Lin28a knockdown cells. CONCLUSION Our findings suggest that the C/EBPβ-Lin28a axis is a driver of restenosis progression, and presents a promising therapeutic target for restenosis.
