Evaluation value of contrast enhanced ultrasound quantitative parameters in ischemic-type biliary lesions after liver transplantation-a prospectively study.

Purpose: To explore the evaluation value of contrast enhanced ultrasound (CEUS) quantitative parameters in ischemic-type biliary lesions after liver transplantation to assist its early-diagnosis.

Methods: Patients who underwent liver transplantation and intravenous CEUS at Beijing Friendship Hospital, Capital Medical University from June 25, 2020 to December 28, 2022 and were diagnosed with Ischemic-type biliary lesions (ITBLs) by Magnetic Resonance Cholangiopancreatography (MRCP) or Endoscopic Retrograde Cholangiopancreatography (ERCP) or Percutaneous Transhepatic Cholangiography (PTC) were prospectively enrolled. SonoLiver software was used to quantitatively analyze the contrast images, transplanted livers with normal biliary tracts as the control group.

Metalgel Fiber with Excellent Electrical and Mechanical Properties.

With the rapid advancement of soft electronics, particularly the rise of fiber electronics and smart textiles, there is an urgent need to develop high-performance fiber materials with both excellent electrical and mechanical properties. However, existing fiber materials including metal fibers, carbon-based fibers, intrinsically conductive polymer fibers, and composite fibers struggle to simultaneously meet the requirements. Here, we introduce a metalgel fiber with a unique structure.

Targeting MAPK14 by Lobeline Upregulates Slurp1-Mediated Inhibition of Alternative Activation of TAM and Retards Colorectal Cancer Growth.

Colorectal cancer (CRC) usually creates an immunosuppressive microenvironment, thereby hindering immunotherapy response. Effective treatment options remain elusive. Using scRNA-seq analysis in a tumor-bearing murine model, it is found that lobeline, an alkaloid from the herbal medicine lobelia, promotes polarization of tumor-associated macrophages (TAMs) toward M1-like TAMs while inhibiting their polarization toward M2-like TAMs.

Multiplexed inhibition of immunosuppressive genes with Cas13d for combinatorial cancer immunotherapy.

The complex nature of the immunosuppressive tumor microenvironment (TME) requires multi-agent combinations for optimal immunotherapy. Here we describe multiplex universal combinatorial immunotherapy via gene silencing (MUCIG), which uses CRISPR-Cas13d to silence multiple endogenous immunosuppressive genes in the TME, promoting TME remodeling and enhancing antitumor immunity. MUCIG vectors targeting four genes delivered by adeno-associated virus (AAV) (Cd274/Pdl1, Lgals9/Galectin9, Lgals3/Galectin3 and Cd47; AAV-Cas13d-PGGC) demonstrate significant antitumor efficacy across multiple syngeneic tumor models, remodeling the TME by increasing CD8 T-cell infiltration while reducing neutrophils.

Liver transplantation for homozygous familial hypercholesterolemia: a retrospective analysis from Chinese experience.

Background: Homozygous familial hypercholesterolaemia (HoFH) increases risk of premature cardiovascular events and cardiac death. In severe cases of HoFH, clinical signs and symptoms cannot be controlled well by non-surgical treatments, liver transplantation (LT) currently represents the viable option.

Method: To assess the clinical efficacy, prognosis, and optimal timing of LT for HoFH, a retrospective analysis was conducted on the preoperative, surgical conditions, and postoperative follow-up of children who received an LT for HoFH at the Beijing Friendship Hospital over the period from December 2014 to August 2022.
