Article Abstract
Ethnopharmacological Relevance: Dachaihu Decoction (DD), a classic Chinese herbal prescription, is composed of radix of Bupleurum chinense DC. (Chaihu), radix of Scutellaria baicalensis Georgi (Huangqin), radix of Paeonia lactiflora Pall. (Baishao), rhizoma of Pinellia ternata (Thunb.) Breit. (Banxia), fructus of Citrus aurantium L. (Zhishi), rhizoma of Zingiber officinale Rosc. (Shengjiang), fructus of Ziziphus jujuba Mill. (Dazao) and rhizoma of Rheum officinale Baill. (Dahuang). DD has the traditional effects of soothing the liver, relieving depression and clearing heat from the stomach, and is mainly used to treat heat stagnation in the liver and stomach.
Aim Of The Study: Dachaihu decoction (DD), a classic prescription commonly used in clinical practice for the treatment of pancreatitis and cholecystitis. Although its pharmacological effects are clear, the efficacy components and mechanism of action remain intricate and difficult to clarify.
Materials And Methods: The action targets and components of the anti-inflammatory activity of DD were predicted by network pharmacology; the effective components and targets were verified by HPLC and qPCR; the efficacy markers of DD were further screened by in vitro experiments; the pharmacological value of DD and its components compatibility were evaluated by in vitro experiments.
Results: The key targets MMP9, JAK2, MAP2K1 and NR3C1 were screened by network pharmacology; HPLC analysis showed that paeoniflorin, naringin, hesperidin, neohesperidin, baicalin, wogonoside, baicalein and saikosaponin B were identified as potential efficacy markers of DD; molecular docking combined with qPCR verification suggested that baicalin, naringin, neohesperidin, hesperidin and baicalein and wogonoside had certain ability to regulate above targets; in vitro studies revealed that paeoniflorin, naringin, hesperidin, neohesperidin, baicalin, wogonoside, baicalein and saikosaponin B could inhibit the release of NO, pancreatic lipase and α-glucosidase; after comprehensive comparison and analysis, naringin, hesperidin, neohesperidin, baicalin, wogonoside, baicalein and saikosaponin B were selected as the efficacy markers of DD; in vivo studies indicated that DD and its efficacy markers (components compatibility) had definite therapeutic effects on guinea pigs with cholecystitis.
Conclusions: The efficacy markers of DD including naringin, hesperidin, neohesperidin, baicalin, wogonoside, baicalein and saikosaponin B can be used as components compatibility to exert anti-inflammatory activity. In addition, a method for obtaining the compatibility of efficacy markers by simplifying the prescription is initially established.

Development and Validation of a Scaffold-Free Human Multilineage Spheroid Model for Early Stage Cholangiopathies Driven by Cholangiocyte Senescence.

Background And Aims: Cholangiopathies, including primary sclerosing cholangitis (PSC), primary biliary cholangitis (PBC), and post-COVID-19 cholangiopathy (PCC), involve chronic cholangiocyte injury, senescence, epithelial-stromal crosstalk, and progressive fibrosis. However, effective in vitro models to capture these interactions are limited. Here, we present a scaffold-free 3D multilineage spheroid model, composed of hepatocyte-like cells (HepG2), cholangiocytes (H69), and hepatic stellate cells (LX-2), designed to recapitulate early fibrogenic responses driven by senescent cholangiocytes.

Acute Myeloid Leukemia (AML) is a heterogeneous hematological malignancy with an altered bone marrow microenvironment sheltering leukemic stem cells (LSCs). LSCs are characterized as self-renewing and highly proliferative cancer stem cells and accumulate abnormal genetic and epigenetic factors contributing to their uncontrolled proliferation. Chromosomal translocation t(9;11)(p22;q23) forms fusion oncoprotein, MLL-AF9, and regulates the transcription factor, C-Myb, which is highly expressed in AML.

Background: While highly efficacious for numerous cancers, immune checkpoint inhibitors (ICIs) can cause unpredictable and potentially severe immune-related adverse events (irAEs), underscoring the need to understand irAE biology.
Methods: We used a multidimensional approach incorporating single-cell RNA sequencing, mass cytometry, multiplex cytokine assay, and antinuclear antibody (ANA) profiling to characterize the peripheral immune landscape of patients receiving ICI therapy according to irAE development.
Results: Analysis of 162 patients revealed that individuals who developed clinically significant irAEs exhibited a baseline proinflammatory, autoimmune-like state characterized by a significantly higher abundance of CD57 T and natural killer (NK) T cells, plasmablasts, proliferating and activated CXCR3 lymphocytes, CD8 effector and terminal effector memory T cells, along with reduced NK cells and elevated plasma ANA levels.

Short Tandem Repeats (STRs) are the standard technique used in forensic genetics for individual identification due to their high polymorphism and robustness. Although Capillary Electrophoresis (CE) enables the analysis of many STRs, Next-Generation Sequencing (NGS) offers enhanced resolution and the ability to detect STRs' isoalleles and their flanking regions, enhancing the discrimination power of this analysis. Despite the fact that STR kits for NGS are well standardized for evaluating forensic samples, there is no data on their effectiveness in differentiating monozygotic (MZ) twins, which are indistinguishable by CE.
