Deep Learning for Discrimination of Early Spinal Tuberculosis from Acute Osteoporotic Vertebral Fracture on CT.

Background: Early differentiation between spinal tuberculosis (STB) and acute osteoporotic vertebral compression fracture (OVCF) is crucial for determining the appropriate clinical management and treatment pathway, thereby significantly impacting patient outcomes.

Objective: To evaluate the efficacy of deep learning (DL) models using reconstructed sagittal CT images in the differentiation of early STB from acute OVCF, with the aim of enhancing diagnostic precision, reducing reliance on MRI and biopsies, and minimizing the risks of misdiagnosis.

Methods: Data were collected from 373 patients, with 302 patients recruited from a university-affiliated hospital serving as the training and internal validation sets, and an additional 71 patients from another university-affiliated hospital serving as the external validation set.

Targeting cholesterol-dependent adrenal steroidogenesis for management of primary aldosteronism.

Primary aldosteronism (PA) is a common, salt-sensitive form of endocrine hypertension. Compared with essential hypertension (EH), PA is more susceptible to cardiorenal complications and metabolic risks. However, PA has a low screening rate and a poor response to mineralocorticoid receptor antagonists (MRAs).

Prediction of PD-L1 tumor positive score in lung squamous cell carcinoma with H&E staining images and deep learning.

Background: Detecting programmed death ligand 1 (PD-L1) expression based on immunohistochemical (IHC) staining is an important guide for the treatment of lung cancer with immune checkpoint inhibitors. However, this method has problems such as high staining costs, tumor heterogeneity, and subjective differences among pathologists. Therefore, the application of deep learning models to segment and quantitatively predict PD-L1 expression in digital sections of Hematoxylin and eosin (H&E) stained lung squamous cell carcinoma is of great significance.

Effects of transcranial magnetic stimulation combined with extracorporeal shockwave therapy for poststroke spasticity: study protocol for a randomised controlled trial.

Tau is a receptor with low affinity for glucocorticoids and is required for glucocorticoid-induced bone loss.

Glucocorticoids (GCs) are the most prescribed anti-inflammatory and immunosuppressive drugs. However, their use is often limited by substantial side effects, such as GC-induced osteoporosis (GIO) with the underlying mechanisms still not fully understood. In this study, we identify Tau as a low-affinity binding receptor for GCs that plays a crucial role in GIO.

Results: We observed a significant correlation between increased kappa opioid receptor (KOP receptor) expression and better prognosis in patients with glioma.

Roles of blood monocytes carrying TREM2 mutation in pathogenesis of Alzheimer's disease and its therapeutic potential in APP/PS1 mice.

Introduction: The triggering receptor expressed on myeloid cells 2 (TREM2) arginine-47-histidine (R47H) mutation is a significant risk for Alzheimer's disease (AD) with unclear mechanisms. Previous studies focused on microglial amyloid-β (Aβ) phagocytosis with less attention on the impact of TREM2 mutation on blood monocytes.

Methods: Bone marrow transplantation (BMT) models were used to assess the contribution of blood monocytes carrying TREM2 mutation to AD.

Efficacy and Safety of Chemotherapy or EGFR-TKIs as First-Line Therapy in NSCLC Patients Harboring Non-Ex 20 Ins Uncommon EGFR Mutations: A Retrospective Study in China.

Background: Uncommon EGFR mutations are a kind of heterogeneous group of mutations with various responses to EGFR-TKIs and are often excluded from most prospective clinical trials. In this real-world retrospective study, we retrospectively compared the efficacy and safety of chemotherapy or various generations of EGFR-TKIs as first-line therapy in NSCLC Chinese patients harboring non-ex 20 ins uncommon EGFR mutations.

Methods: We enrolled 139 NSCLC patients with non-ex 20 ins uncommon EGFR mutations in this study retrospectively.

Differences in severity of diffuse and focal coronary stenosis between visual and quantitative assessment.

Background: Coronary Artery Disease (CAD) is a leading cause of mortality, with an increasing number of patients affected by coronary artery stenosis each year. Coronary angiography (CAG) is commonly employed as the definitive diagnostic tool for identifying coronary artery stenosis. Physician Visual Assessment (PVA) is often used as the primary method to determine the need for further intervention, but its subjective nature poses challenges.

The miR-23a/27a/24 - 2 cluster drives immune evasion and resistance to PD-1/PD-L1 blockade in non-small cell lung cancer.

Programmed cell death protein ligand-1 (PD-L1) and major histocompatibility complex I (MHC-I) are key molecules related to tumor immune evasion and resistance to programmed cell death protein 1 (PD-1)/PD-L1 blockade. Here, we demonstrated that the upregulation of all miRNAs in the miR-23a/27a/24 - 2 cluster was correlated with poor survival, immune evasion and PD-1/PD-L1 blockade resistance in patients with non-small cell lung cancer (NSCLC). The overexpression of all miRNAs in the miR-23a/27a/24 - 2 cluster upregulated PD-L1 expression by targeting Cbl proto-oncogene B (CBLB) and downregulated MHC-I expression by increasing the level of eukaryotic initiation factor 3B (eIF3B) via the targeting of microphthalmia-associated transcription factor (MITF).

KCNJ15 inhibits chemical-induced lung carcinogenesis and progression through GNB1 mediated Hippo pathway.

Polycyclic aromatic hydrocarbons (PAHs) are important environmental carcinogens that can cause lung cancer. However, the underlying epigenetic mechanism during PAHs-induced lung carcinogenesis has remained largely unknown. Previously, we screened some novel epigenetic regulatory genes during 3-methylcholanthrene (3-MCA)-induced lung carcinogenesis, including the potassium inwardly rectifying channel subfamily J member 15 (KCNJ15) gene.

SND1-SMARCA5 interaction strengthened by PIM promotes the proliferation, metastasis, and chemoresistance of esophageal squamous cell carcinoma.

Chromatin remodeling plays a pivotal role in the progression of esophageal squamous cell carcinoma (ESCC), but the precise mechanisms remain poorly understood. Here, we elucidated the critical function of staphylococcal nuclease and tudor domain-containing 1 (SND1) in modulating chromatin dynamics, thereby driving ESCC progression in both in vitro and in vivo models. Our data revealed that SND1 was markedly overexpressed in ESCC cell lines.
