Hepatobiliary organoid research: the progress and applications.

Organoid culture has emerged as a forefront technology in the life sciences field. As " micro-organs", organoids can faithfully recapitulate the organogenesis process, and conserve the key structure, physiological function and pathological state of the original tissue or organ. Consequently, it is widely used in basic and clinical studies, becoming important preclinical models for studying diseases and developing therapies.

Lactiplantibacillus plantarum TCCC11824 exerts hypolipidemic and anti-obesity effects through regulation of NF-κB-HMGCR pathway and gut microbiota in mice and clinical patients.

A strong association exists between the high-fat diet (HFD) and the incidence of obesity, hyperlipidemia and cardiovascular disease, affecting an increasing number of individuals. More and more research has shown that probiotics and gut microbiota play important roles in dietary absorption, metabolism, and general health of the host. This aim of this study was to evaluate the therapeutic effects and the underlying mechanisms of Lactiplantibacillus plantarum TCCC11824 (CGMCC 8198) on hyperlipidemia and obesity in mice and humans.

Does the size of the neuroendocrine-carcinoma component determine the prognosis of gallbladder cancer?

Background: Gallbladder mixed neuroendocrine-non-neuroendocrine neoplasm generally consists of a gallbladder neuroendocrine tumor and a non-neuroendocrine component. The World Health Organization (WHO) in 2019 established a guideline requiring each component, both neuroendocrine and non-neuroendocrine, to account for a minimum of 30% of the tumor mass.

Methods: Patients after surgery resection and diagnosed at microscopy evaluation with pure gallbladder neuroendocrine carcinoma (GBNEC), gallbladder mixed adeno-neuroendocrine carcinoma (GBMANEC, GBNEC≥30%), and gallbladder carcinoma mixed with a small fraction of GBNEC (GBNEC <30%) between 2010 and 2022 at West China Hospital of Sichuan University were collated for the analyses.

A Review of Ultrasonic Treatment in Mineral Flotation: Mechanism and Recent Development.

Ultrasonic treatment has been widely used in the mineral flotation process due to its advantages in terms of operational simplicity, no secondary pollutant formation, and safety. Currently, many studies have reported the effect of ultrasonic treatment on mineral flotation and shown excellent flotation performance. In this review, the ultrasonic mechanisms are classified into three types: the transient cavitation effect, stable cavitation effect, and acoustic radiation force effect.

Unraveling early recurrence of risk factors in Gallbladder cancer: A systematic review and meta-analysis.

Background: Gallbladder cancer (GBC) is the most prevalent biliary tract tumor characterized by a high incidence of recurrence, even after curative-intent surgery. The object of this systematic review and meta-analysis was to investigate the risk factors related to early recurrence (ER).

Methods: A systematic literature review was conducted in PubMed, Embase, Cochrane Library, and Web of Science to identify published articles up to February 2024.

Prognostic factors for resected cases with gallbladder carcinoma: a systematic review and meta-analysis.

Objective: Current meta-analysis was performed to systematically evaluate the potential prognostic factors for overall survival among resected cases with gallbladder carcinoma.

Methods: PubMed, EMBASE, and the Cochrane Library were systematically retrieved and hazard ratio (HR) and its 95% confidence interval were directly extracted from the original study or roughly estimated via Tierney's method. Standard Parmar modifications were used to determine pooled HRs.

Exosomal long non-coding RNA TRPM2-AS promotes angiogenesis in gallbladder cancer through interacting with PABPC1 to activate NOTCH1 signaling pathway.

Background: Abnormal angiogenesis is crucial for gallbladder cancer (GBC) tumor growth and invasion, highlighting the importance of elucidating the mechanisms underlying this process. LncRNA (long non-coding RNA) is widely involved in the malignancy of GBC. However, conclusive evidence confirming the correlation between lncRNAs and angiogenesis in GBC is lacking.

The prognostic value of combined preoperative PLR and CA19-9 in patients with resectable gallbladder cancer.

The platelet to lymphocyte ratio (PLR) is the marker of host inflammation and it is a potential significant prognostic indicator in various different tumors. The serum carbohydrate antigen 19-9 (CA19-9) is a tumor-associated antigen and it is associated with poor prognosis of gallbladder cancer (GBC). We aimed to analyze the prognostic value of the combination of preoperative PLR and CA19-9 in patients with GBC.

Prognostic value of combined preoperative inflammatory marker neutrophil-lymphocyte ratio and platelet distribution width in patients with gallbladder carcinoma.

Background: The neutrophil-lymphocyte ratio (NLR) and platelet distribution width (PDW) are associated with poor prognosis in various cancers. We aimed to analyze the prognostic value of the combination of preoperative NLR and PDW in patients with gallbladder carcinoma (GBC).

Methods: A total of 287 GBC patients who underwent curative-intent surgery in our institution was included.

PP4R1 promotes glycolysis and gallbladder cancer progression through facilitating ERK1/2 mediated PKM2 nuclear translocation.

Gallbladder cancer (GBC) is a common solid tumor of the biliary tract with a high mortality rate and limited curative benefits from surgical resection. Here, we aimed to elucidate the pathogenesis of GBC from the perspective of molecular mechanisms and determined that protein phosphatase 4 regulator subunit 1 (PP4R1) is overexpressed in GBC tissues and contributes to poor prognosis. Through a series of in vitro and in vivo experiments, we demonstrated that PP4R1 overexpression improved tumorigenesis in GBC cells.
