Background: Pancreatic ductal adenocarcinoma (PDAC) is characterized by a complex tumor microenvironment (TME) that influences tumor progression and therapeutic responses. TYRO protein tyrosine kinase binding protein (TYROBP), a transmembrane polypeptide involved in immune cell signaling, has been implicated in PDAC and associated with M2 macrophage polarization.

Methods: We investigated the correlation between TYROBP expression and M2 macrophage infiltration in PDAC tissues using multiplex immunofluorescence staining.

Objectives: This research investigates how the SERPINE1-associated tumor microenvironment influences anti-PD-1 treatment response in gastric carcinoma (GC).

Methods: Bioinformatics analysis, cellular experiments, and animal models were employed to quantify the levels of NFATC2, SERPINE1, JAK3, STAT3, and to explore their associations with various biological behaviors of GC cells, encompassing proliferation, migration, invasiveness, EMT, and immune cell infiltration. Additionally, by constructing a GC tumor-bearing model, we assessed the efficacy of knocking down SERPINE1 in combination with anti-PD-1 therapy.

Purpose: To investigate the association between miR-146a/HDAC2 and their regulatory roles on the PI3K expression during pancreatitis.

Methods: Rat pancreatic AR42J cells were treated with LPS for simulating pancreatitis. Expression levels of inflammatory factors (IL-6, TNF-α) and miR-146a were d determine the optimal LPS concentration for establishing an in vitro pancreatitis model Cell proliferation and apoptosis were analyzed using CCK-8 and flow cytometry Immunofluorescence was performed to assess co-localization of HDAC2 and PI3K.

Background: Chronic pancreatitis (CP) is marked by persistent inflammation and fibrosis of the pancreas, often causing severe abdominal pain. The pain mechanism involves complex interactions between pancreatic inflammation and spinal nerve activity. Histone deacetylase 2 (HDAC2) is implicated in neural processes and pain modulation, making it a potential target for CP pain management.

Background And Aim: M2-polarized tumor-associated macrophages (M2 TAMs) are known to promote cancer progression, and exosomes are crucial mediators of communication within the tumor microenvironment (TME). However, the specific role of exosomes derived from M2 TAMs in pancreatic cancer (PC) progression remains poorly understood. Tyrosine kinase binding protein (TYROBP, also known as DAP12 for DNAX activating protein-12) is a transmembrane signal transduction polypeptide that interacts with immune cell receptors, influencing cellular functions via signal transduction pathways.

Article Synopsis
  • The study focuses on extrahepatic bile duct cancer (EBDC) that often spreads to the liver, aiming to explore its features, identify prognostic factors, and evaluate long-term outcomes for patients with liver metastasis.
  • Researchers analyzed data from 1,922 EBDCLM patients, using statistical methods to determine factors influencing overall survival (OS) and cancer-specific survival (CSS), and created a predictive nomogram.
  • Key findings revealed that age, treatment methods (surgery and chemotherapy), and presence of metastases (brain and lung) significantly impact patient survival, with the nomogram proving effective for predicting outcomes and aiding clinical decisions.

Objective: The aim of this study was to evaluate the residual volume of liver reserve function in liver cancer patients using three-dimensional reconstruction technique (3D technology) and the indocyanine green (ICG) excretion test.

Methods: A retrospective analysis was conducted, and data were collected from 90 liver cancer patients in Ganzhou People's Hospital between January 2017 and December 2021. The control group underwent preoperative resectability evaluation based on traditional two-dimensional images, whereas the experimental group underwent digital three-dimensional reconstruction technique combined with indocyanine green (ICG) excretion test.

The chemical-industrial production of organic semiconductors urgently needs a cheap and fast approach to determine the components' proportion of the reaction system. In the present work, the Gaussian peak fitting method was applied to process monobromo and dibromo-substituted perylene diimide mixed solutions' ultraviolet-visible absorption curves. The functional relationship formula between the peak-intensity ratio and the component ratio is then concluded.

The contents of 2011 Tokyo Declaration on Japanese Acupuncture and Moxibustion (Declaration for short) and its effect on development situation, current status, features, opportunities and challenges of Japanese acupuncture and moxibustion are introduced, some proposals brought up in the Declaration are analyzed as well. The Declaration summarizes six characteristics of Japanese acupuncture and moxibustion, including paying great attention to palpation techniques such as pulse and abdominal diagnosis, always selecting response point in the meridian during acupuncture treatment, etc. Also six proposals have been brought up to promote the development of Japanese acupuncture and moxibustion, such as being devoted to spread the latest knowledge of acupuncture and moxibustion to medical professionals and the public in order to get correct understanding and proper evaluation, etc.
