The biological macromolecules constructed Matrigel for cultured organoids in biomedical and tissue engineering.

Matrigel is the most commonly used matrix for 3D organoid cultures. Research on the biomaterial basis of Matrigel for organoid cultures is a highly challenging field. Currently, many studies focus on Matrigel-based biological macromolecules or combinations to construct natural Matrigel and synthetic hydrogel scaffolds based on collagen, peptides, polysaccharides, microbial transglutaminase, DNA supramolecules, and polymers for organoid culture.

Ultrasomics in liver cancer: Developing a radiomics model for differentiating intrahepatic cholangiocarcinoma from hepatocellular carcinoma using contrast-enhanced ultrasound.

Background: Hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) represent the predominant histological types of primary liver cancer, comprising over 99% of cases. Given their differing biological behaviors, prognoses, and treatment strategies, accurately differentiating between HCC and ICC is crucial for effective clinical management. Radiomics, an emerging image processing technology, can automatically extract various quantitative image features that may elude the human eye.

Supramolecular Photothermal Nanomedicine Mediated Distant Tumor Inhibition via PD-1 and TIM-3 Blockage.

Supramolecular nanoparticles for photothermal therapy (PTT) have shown promising therapeutic efficacy in the primary tumor and great potential for turning the whole-body immune microenvironment from "cold" to "hot," which allows for the simultaneous treatment of the primary tumor and the metastatic site. In this work, we develop a liposome-based PTT nanoparticle through the self-assembly of FDA-approved intravenous injectable lipids and a photothermal agent, indocyanine green (ICG). The obtained ICG-liposome shows long-term storage stability, high ICG encapsulation efficiency (>95%), and enhanced near-infrared (NIR) light-triggered photothermal reaction both and .

Anticancer bioactive peptides suppress human colorectal tumor cell growth and induce apoptosis via modulating the PARP-p53-Mcl-1 signaling pathway.

Aim: We have reported novel anticancer bioactive peptides (ACBPs) that show tumor-suppressive activities in human gastric cancer, leukemia, nasopharyngeal cancer, and gallbladder cancer. In this study, we investigated the effects of ACBPs on human colorectal cancer and the underlying mechanisms.

Methods: Cell growth and apoptosis of human colorectal tumor cell line HCT116 were measured using cell proliferation assay and flow cytometry, respectively.

Dynamic Changes in Phenotypic Groups in Patients with Stable Angina Pectoris after Treatment with Xinxuekang Capsule: A Randomized Controlled Trial.

Objective: To reveal the cutoff point and influencing factors in the dynamic change in phenotypic group in patients with stable angina pectoris (SAP) after Xinxuekang capsule treatment.

Methods: Five hundred and seventy-six SAP patients were randomly assigned to receive Xinxuekang (XXK) capsules or Compound Danshen (CDS) tablets for 8 weeks. Global similarity degree analysis and nonlinear mixed effects modeling (NONMEM) were employed to reveal the cutoff points and influencing factors in dynamic changes in the SAP phenotypic group.

Anticancer bioactive peptide (ACBP) inhibits gastric cancer cells by upregulating growth arrest and DNA damage-inducible gene 45A (GADD45A).

Recently, we reported that anticancer bioactive peptide (ACBP), purified from goat spleens immunized with human gastric cancer extracts, significantly inhibited gastric cancer cells in vitro and gastric tumors in vivo via repressing cell growth and promoting apoptosis, making it a promising potential biological anticancer drug. However, it is not known what genes are functionally required for the ACBP effects. Here, we first found that two tumor suppressor genes, cyclin-dependent kinase inhibitor 2B (CDKN2B) and growth arrest and DNA damage-inducible alpha (GADD45A), were upregulated significantly in the cells with ACBP treatment by microarray screening and the findings were validated by real-time RT-PCR.

[Anaplastic large cell lymphoma: an array-based comparative genomic hybridization study].

Objective: To use array-based comparative genomic hybridization (aCGH) technology to study the molecular cytogenetic abnormalities of anaplastic large cell lymphoma (ALCL) at genome level.

Methods: ALK protein expression and molecular genetic abnormalities were detected by immunohistochemistry and fluorescence in situ hybridization, respectively, in 25 cases of ALCL. Any chromosomal gains/losses were detected by aCGH and correlated with ALK status.

Differential diagnosis of isolated calf muscle vein thrombosis and gastrocnemius hematoma by high-frequency ultrasound.

Background: Differential diagnosis of isolated calf muscle vein thrombosis (ICMVT) and gastrocnemius hematoma is essential for early identification of deep vein thrombosis (DVT). This study aimed to investigate the diagnostic value of high-frequency color Doppler ultrasound for differential diagnosis of ICMVT and gastrocnemius hematoma.

Methods: A retrospective case series of 35 ICMVT (M:F, 21:14; mean age (64.

[Retrospective analysis of ultrasonography for autoimmune pancreatitis].

Objective: To explore the sonographic characteristics of autoimmune pancreatitis (AIP).

Methods: The ultrasonographic features and clinical data of 8 AIP patients were analyzed retrospectively and compared with the findings of computed tomography and magnetic resonance imaging.

Results: Ultrasound images showed diffuse pancreatic swelling (n = 6), focal pancreatic head thickening (n = 1) and tail enlargement (n = 1).
