AI Article Synopsis
- Gastric cancer is common in Asia, often leading to poor outcomes after surgery and high recurrence rates, with Helicobacter pylori identified as a key factor in its development.
- The study uses advanced methods like gene regulatory networks and landscape theory to quantitatively analyze how different concentrations of Helicobacter pylori affect gene expression and contribute to gastric cancer progression.
- Results highlight critical stages of infection that can serve as early warning signals for gastric cancer, bridging research and clinical practice with important implications for treatment and prevention.
Article Abstract
Gastric cancer is highly prevalent in Asia and is characterized by poor prognosis post-surgery and a high recurrence rate within five years. Research has highlighted the role of Helicobacter pylori in initiating or accelerating gastric cancer development. However, quantitative analysis of its impact on gastric cancer carcinogenesis is still lacking. This study employs gene regulatory networks and landscape and flux theory, integrating genetic and epigenetic factors, to quantitatively elucidate how Helicobacter pylori influences gastric cancer progression. Varied Helicobacter pylori infection concentrations lead to significant shifts in system thermodynamic and dynamic driving forces, altering gene expression levels. Quantitative analysis of entropy production rate and mean-flux in the gastric cancer system reveals the global changes in thermodynamic and dynamic driving forces. Coupled with autocorrelation, cross correlation, and variance analysis, we pinpoint critical stages of Helicobacter pylori infection, serving as early warning signals for gastric cancer. This approach bridges theoretical and clinical realms, dynamically assessing Helicobacter pylori's impact on gastric cancer and identifying crucial early warning signals, with significant clinical and translational implications.

Background: To explore the potential impact of lymphovascular invasion (LVI) on overall survival (OS) of pN0 stage gastric cancer (GC) after curative resection.
Methods: A total of 497 GC patients who underwent curative gastrectomy and postoperative pathology proved negative lymph node metastasis between January 2015 and December 2018 in our center were enrolled in this study. All patients were divided into two groups according to the status of LVI.

Context: Cancer-related fatigue (CRF) can affect patients undergoing chemotherapy severely. A comprehensive intervention targeted for reducing CRF is lacking.
Objectives: To evaluate the effectiveness of an innovative multi-faceted web-based patient-empowered CRF management program for improving CRF, perceived self-efficacy for fatigue self-management (PSEFSM), physical activity, quality of sleep, anxiety, depression, pain and quality of life (QoL) among gastric cancer patients undergoing chemotherapy in China.

Gastric cancer (GC) is a common malignant tumor and the third most common cancer in China in terms of mortality. Stomach microorganisms play complex roles in the development of GC. The carcinogenic mechanism of Helicobacter pylori has been elucidated, and there is much evidence that other microorganisms in the gastric mucosa are also heavily involved in the disease progression of this cancer.

Lipid rafts are highly heterogeneous and dynamic microdomains involved in molecule trafficking and signaling transduction. This study investigates the role of lipid rafts in gastric cancer and their key regulators. Analyzing FFPE samples from 111 gastric cancer patients, we found that high lipid raft levels predict poor prognosis.

Background: Vonoprazan and amoxicillin (VA) dual therapy as a mainstream Helicobacter pylori regimen has gained momentum worldwide, but the optimum dosages remain unclear. We aimed to compare the efficacy and safety of VA dual therapy with 2 g amoxicillin or 3 g amoxicillin, and to assess the short-term effects of therapy on the gut microbiota and antibiotic resistome.
Methods: We conducted an open-label, non-inferiority randomised controlled trial at 12 centres in China.
