Association of Morphological Changes in the Posterior Horn of the Meniscus of Knee With Anterior Cruciate Ligament Injury: A New Biological Evaluation Index.

Background: The shape and size of the meniscus are closely related to the stability of the knee joint and the anterior cruciate ligament (ACL) injury. Studies have confirmed the correlation between meniscal morphology and isolated ACL injury.

Purpose: To investigate meniscal parameters, including morphological changes, in participants with isolated ACL injury.

Orthogonal Host-Guest Interactions Enable Programming of Protocell Membranes for Cellular High-Order Assembly and Enhanced Immunogenicity.

The complement system's distinguishing feature is its cell-specific surface ligands. However, the limited scalability and complexity of incorporating surface-customizable ligands into membrane-bound cell-like microassemblages have hindered their widespread adoption in synthetic biology and bioengineering. Here, we present a method for the batch construction of polysaccharide-based microcapsules (polysaccharidosomes, P-somes) with intrinsic functional host membranes capable of docking guest ligands via facile host-guest interactions.

HMPL-306 in relapsed or refractory IDH1- and/or IDH2-mutated acute myeloid leukemia: A phase 1 study.

Background: HMPL-306 has equally high inhibitory activity against mutated isocitrate dehydrogenases 1 and 2 (mIDH1/2).

Methods: This first-in-human, phase 1 dose-escalation/dose-expansion study (this study was registered at ClinicalTrials.gov: NCT04272957) enrolled patients with relapsed/refractory (R/R) acute myeloid leukemia (AML) harboring mIDH1 and/or mIDH2.

Dual targeting PD-L1 and 4-1BB to overcome dendritic cell-mediated lenalidomide resistance in follicular lymphoma.

Immunomodulatory agent lenalidomide is effective in treating follicular lymphoma (FL). We conducted the first trial of immunotherapy rituximab plus lenalidomide in newly diagnosed FL in China (NCT03715309). One-hundred and fifteen patients were enrolled and treated with rituximab 375 mg/m intravenously on day 0 and lenalidomide 25 mg orally on day 1-10 for 6 cycles of induction treatment, as well as lenalidomide for 6 cycles and rituximab for 8 cycles of maintenance treatment.

Novel oral compound Z526 mitigates cancer-associated cachexia via intervening NF-κB signaling and oxidative stress.

Cancer-associated cachexia (CAC) is a severe metabolic disorder syndrome mainly characterized by muscle and fat loss, which accounts for one-third of cancer-related deaths. No effective therapeutic approach that could fully reverse CAC is available. NF-κB signaling and oxidative stress play vital roles in both muscle atrophy and fat loss in CAC.

A machine learning-based model to predict POD24 in follicular lymphoma: a study by the Chinese workshop on follicular lymphoma.

Background: Disease progression within 24 months (POD24) significantly impacts overall survival (OS) in patients with follicular lymphoma (FL). This study aimed to develop a robust predictive model, FLIPI-C, using a machine learning approach to identify FL patients at high risk of POD24.

Methods: A cohort of 1,938 FL patients (FL1-3a) from seventeen centers nationwide in China was randomly divided into training and internal validation sets (2:1 ratio).

Different Role of PET-CT Evaluation in Newly Diagnosed Follicular Lymphoma Upon Rituximab-Based Chemotherapy and Chemo-Free Immunotherapy.

Newly diagnosed follicular lymphoma (FL) patients usually received first-line rituximab-based immunochemotherapy (R-chemo). Recently, rituximab plus lenalidomide (R2) emerged as an alternative chemo-free immunotherapy. We performed a comparative analysis of positron emission tomography/computed tomography (PET/CT) in FL undergoing R-chemo or R2.

Deep learning model for the automated detection and classification of central canal and neural foraminal stenosis upon cervical spine magnetic resonance imaging.

Background: A deep learning (DL) model that can automatically detect and classify cervical canal and neural foraminal stenosis using cervical spine magnetic resonance imaging (MRI) can improve diagnostic accuracy and efficiency.

Methods: A method comprising region-of-interest (ROI) detection and cascade prediction was formulated for diagnosing cervical spinal stenosis based on a DL model. First, three part-specific convolutional neural networks were employed to detect the ROIs in different parts of the cervical MR images.

Synthesis and evaluation of a novel BODIPY fluorescent probe targeting integrin αβ for cancer diagnosis.

A series of integrin αβ targeting BODIPY-RGD conjugate were designed and synthesized. Their in vitro and in vivo fluorescence imaging behaviors were investigated. The small molecule compound was designed as an optical imaging near-infrared fluorescent dye which was combined RGD peptide with the meso-amide BODIPYs using succinic moiety as a spacer.

Prediction of pathological response and lymph node metastasis after neoadjuvant therapy in rectal cancer through tumor and mesorectal MRI radiomic features.

Establishing predictive models for the pathological response and lymph node metastasis in locally advanced rectal cancer (LARC) treated with neoadjuvant chemoradiotherapy (nCRT) based on MRI radiomic features derived from the tumor and mesorectal compartment (MC). This study included 209 patients with LARC who underwent rectal MRI both before and after nCRT. The patients were divided into a training set (n = 146) and a test set (n = 63).

Targeted agents plus CHOP compared with CHOP as the first-line treatment for newly diagnosed patients with peripheral T-cell lymphoma (GUIDANCE-03): an open-label, multicentre phase 2 clinical trial.

Background: Peripheral T-cell lymphoma (PTCL) is a heterogeneous disease with dismal outcomes. We conducted an open-label, phase 2 nonrandomised, externally controlled study to evaluate the efficacy and safety of targeted agents plus CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) (CHOPX) for PTCL in the front-line setting.

Methods: Eligible patients were ≥18 years of age and newly diagnosed PTCL.

Synthesis and Photodynamic Activities of Pyridine- or Pyridinium-Substituted Aza-BODIPY Photosensitizers.

In this work, various novel pyridinyl- and pyridinium-modified Aza-BODIPY PSs were designed and constructed based on monoiodo Aza-BODIPY PSs ( and ) in an attempt to construct "structure-inherent organelles-targeted" PSs to endow potential organelle-targeting ability. Pyridinyl PSs displayed potent photodynamic efficacy, and monorigidified PSs were very effective. The monorigidified PS with -pyridinyl moiety displayed the most potent photoactivity and negligible dark toxicity with a favorable dark/phototoxicity ratio (>4800).

In vivo fluorescence imaging of nanocarriers in near-infrared window II based on aggregation-caused quenching.

Accurate fluorescence imaging of nanocarriers in vivo remains a challenge owing to interference derived mainly from biological tissues and free probes. To address both issues, the current study explored fluorophores in the near-infrared (NIR)-II window with aggregation-caused quenching (ACQ) properties to improve imaging accuracy. Candidate fluorophores with NIR-II emission, ACQ984 (λ = 984 nm) and IR-1060 (λ = 1060 nm), from the aza-BODIPY and cyanine families, respectively, were compared with the commercial fluorophore ICG with NIR-II tail emission and the NIR-I fluorophore P2 from the aza-BODIPY family.
