Objective: This study aims to investigate the correlation between the tumor-stroma ratio (TSR) and peritoneal metastasis (PM) in gastric cancer (GC) and constructs a diagnostic model based on preoperative examination data.
Methods: To determine the feasibility of obtaining TSR in GC patients through preoperative examinations, the consistency of TSR between endoscopic biopsy tissues and postoperative histopathological tissues was evaluated. Additionally, the correlation between TSR and PM in GC was analyzed using Gene Expression Omnibus (GEO) datasets.

Objective: This study aims to investigate the monthly variation patterns of bioelectrical impedance (BEI) along 24 meridian pathways in healthy individuals.
Methods: A cohort of 684 healthy middle-aged participants from North China was enrolled between July 1, 2017, and September 5, 2020. BEI measurements were consistently recorded along the 24 meridian pathways over the study period.

PIK3CA, which encodes protein p110α, is one of the most frequently mutated oncogenes and a promising drug-target for human cancer. Previously, we demonstrate that p85β is released from PI3K complex which contain PIK3CA helical domain mutations and translocates into nucleus to regulate tri-methylation of H3K27, thereby promoting tumorigenicity. Here, we identify DIRAS2 and SOWAHB as target genes of nuclear p85β in PIK3CA-helical-domain-mutant tumors.

Background: Gastrointestinal stromal tumor (GIST) was very rare in the gastrointestinal (GI) tract. Most GISTs were asymptomatic at early stage. Therefore, it was of great significance to explore the prognostic factors of patients with GIST.
