Objective To investigate the registration rate and trend of pulmonary tuberculosis complicated with diabetes mellitus (PTB-DM) in Wuhan from 2020 to 2024, and to provide scientific evidence for formulating PTB-DM prevention and control policies. Methods PTB-DM case data in Wuhan (2020-2024) were collected through the Infectious Disease Registration and Management Information System. Joinpoint regression model was employed to analyze the trend of registration rates of PTB-DM among the general population and across different regions, genders, and age groups. ARIMA model was used to predict the short-term prevalence of PTB-DM. Results Among 26275 pulmonary tuberculosis cases registered in Wuhan (2020-2024), 2669 cases (10.16%) were PTB-DM. The average annual registration rate of PTB-DM was 3.96/100,000, increasing from 2.74/100,000 in 2020 to 5.40/100,000 in 2024 (APC=19.07%, 95% CI:12.99%-26.92%, P<0.001). The PTB-DM registration rates showed an upward trend across different regions, genders, and age groups in Wuhan, with higher registration rates observed in near urban area, males, and individuals aged 60~64 and 65 years and above (χ²=99.566, P<0.001; χ²=781.891, P<0.001; χ²=2211.930, P<0.001). ARIMA model predicted that the prevalence of PTB-DM in Wuhan would remain stable and fluctuating in the short time. Conclusion PTB-DM registration rate in Wuhan increases from 2020 to 2024. Near urban area, males, and elderly populations are high risk groups. Future efforts should focus on strengthening the prevention and control of PTB-DM among these populations.

This paper provides a systematic review of the policies, regulations, and management requirements in the development and use of in vitro diagnostic reagents by healthcare institutions, along with their current implementation status both domestically and internationally, and includes a case analysis of the pilot program at Peking Union Medical College Hospital (PUMCH). The Medical Affairs Department of PUMCH, serving as the leading and operational management unit, established a multi-department collaborative governance structure and developed a full-lifecycle management model encompassing project selection, manufacturing approach determination, regulatory submission and approval, batch production, and clinical implementation. Under this management model, the hospital successfully completed five projects within just one year, achieving the highest number of project filings nationwide. Economic benefit evaluation of the first approved reagent, which is urgently required by clinical practice and named allergen-specific immunoglobulin E detection assay for Fraxinus pennsylvanica pollen, demonstrates that the project realized controllable risk and predictable commercial value, and proves that proactive implementation of systematic management model and project systematic construction is the key to successfully advancing laboratory-developed test programs. The experiences provide both theoretical insights and practical guidance for peer medical institutions seeking to develop and implement self-developed in vitro diagnostic reagents.

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.

Objective To investigate the efficacy of combined telephone and WeChat follow-up for patients discharged with an indwelling closed thoracic drainage tube after surgery for stage Ⅲ tuberculous empyema. Methods Patients with stage Ⅲ tuberculous empyema who were discharged with an indwelling drainage tube from the Department of Thoracic Surgery, Public Health Clinical Center of Chengdu, between November 2021 and November 2022 were enrolled in this study. They were divided into an observation group (combined telephone and WeChat follow-up) and a control group (telephone-only follow-up). The quality of life (QoL), treatment adherence, and recovery outcomes were compared between the two groups. Results A total of 81 patients were included. The observation group consisted of 49 patients (31 males, 18 females) with a mean age of (38.63±15.86) years. The control group consisted of 32 patients (27 males, 5 females) with a mean age of (36.91±17.33) years. The observation group showed significantly better postoperative QoL outcomes in the domains of physical functioning, emotional functioning, physical symptoms, global health status, and overall QoL compared to the control group (all P<0.05). Regarding treatment adherence, the observation group demonstrated superior performance in daily activity duration, use of a respiratory trainer, and adherence to coughing exercises compared to the control group (all P<0.001). The duration of chest tube indwelling was significantly shorter in the observation group (P<0.001). Furthermore, the observation group showed better recovery in albumin and hemoglobin levels (both P<0.05). Conclusion A combined telephone and WeChat follow-up approach can significantly improve the QoL and treatment adherence for patients discharged with an indwelling drainage tube. This method effectively shortens the duration of postoperative tube drainage, promotes nutritional recovery, and accelerates overall postoperative rehabilitation.

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.

Objective:To investigate the feasibility and value of nomogram based on base line clinical and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) characteristics for pretreatment predicting the depth of myometrial invasion and tumor grade of endometrioid endometrial carcinoma (EEC).Methods:Preoperative baseline clinical characteristics and DCE-MRI characteristics of 194 EEC patients were prospectively collected at Obstetrics and Gynecology Hospital, Fudan University from October 2020 to January 2022 and used as a training set. Univariate analysis was conducted to compare baseline clinical characteristics and DCE-MRI quantitative parameters [including tumor volume, and mean, median, and standard deviation of volume transfer constant (K trans), rate constant (K ep), extravascular extracellular volume fraction (V e), and initial area under the enhancement curve (iAUC)] between patients with deep myometrial invasion (DMI) and those with superficial myometrial invasion (SMI), as well as between high-grade and low-grade EEC. Multivariate logistics regression analysis was used to identify independent predictors for the construction of nomogram. An independent external testing set comprising 127 EEC patients was retrospectively collected from Zhongshan Hospital, Fudan University and Zhongshan Hospital, Fudan University (Xiamen Branch). The area under the receiver operating characteristic curve (AUC) and decision curve analysis (DCA) were used for evaluating the model′s predictive performance and clinical net benefit, respectively. Results:(1) The depth of myometrial invasion: univariate analysis showed that in the training set, the EEC patients with DMI differed significantly from those with SMI in clinical characteristics including higher proportion of postmenopausal state and overweight [body mass index (BMI)≥25 kg/m2], and abnormal levels of serum cancer antigen (CA) 125, CA 199, and human epididymis protein 4 (HE4), and in DCE-MRI quantitative parameters including tumor volume, and median, mean, and standard deviation of K trans, median of V e, as well as median, mean, and standard deviation of iAUC (all P<0.05). Multivariate analysis showed that the patient′s menstrual status, BMI, CA 199, tumor volume, and mean of iAUC were independent predictors of the depth of myometrial invasion, and constructed the nomogram (recorded as Nomogram_1), achieving an AUC of 0.861 (95% CI: 0.803-0.919) in the training set. In the independent external testing set, the AUC was 0.876 (95% CI: 0.815-0.938), with corresponding sensitivity of 82.0%, specificity of 80.7%, accuracy of 81.1%, positive predictive value (PPV) of 65.3%, and negative predictive value (NPV) of 91.0% for predicting DMI. (2) The EEC grade: univariate analysis showed that in the training set, high-grade EEC patients differed significantly from low-grade EEC in clinical characteristics including patient′s age, the proportion of postmenopausal state and overweight, and abnormal levels of serum CA 125, and in DCE-MRI quantitative parameters including tumor volume, median, mean, and standard deviation of K trans, median and mean of V e, as well as median, mean, and standard deviation of iAUC (all P<0.05). Multivariate analysis showed that the patient′s menstrual status, BMI, tumor volume, and median of V e emerged as independent predictors of EEC grade, and constructed the nomogram (recorded as Nomogram_2), achieving an AUC of 0.845 (95% CI: 0.786-0.893) in the training set. While in the external testing set, the AUC was 0.819 (95% CI: 0.744-0.894), with corresponding sensitivity of 72.4%, specificity of 72.4%, accuracy of 72.4%, PPV of 43.8%, and NPV of 89.9% for predicting high-grade EEC. (3) The DCA curves demonstrated that both Nomogram_1 and Nomogram_2 yielded obvious positive clinical net benefits across a wide range of threshold probabilities. Conclusion:The nomogram based on pretreatment clinical and DCE-MRI characteristics has the potential to noninvasive predict the depth of myometrial invasion and grade of EEC, providing valuable reference information for clinical management decision-making.
