BACKGROUND Gemcitabine/cisplatin (GP) resistance displays a negative role in treating advanced and metastatic non-small cell lung cancer (NSCLC). Several studies found that the association existed between platelets antigen 125 (CA125) with anticancer drugs. But exact correlation GP platelet activation index remains poorly understood. MATERIAL AND METHODS Pre-chemotherapy CA125 were retrospectively evaluated 169 NSCLC patients. All variables screened by chi-square test then log-rank test....

Background. Cuproptosis, a recently discovered form of cell death, is caused by copper levels exceeding homeostasis thresholds. Although Cu has potential role in colon adenocarcinoma (COAD), its the development COAD remains unclear. Methods. In this study, 426 patients with were extracted from Cancer Genome Atlas (TCGA) database. The Pearson correlation algorithm was used to identify cuproptosis-related lncRNAs. Using univariate Cox regression analysis, least absolute shrinkage and selection...

Regorafenib is a small‐molecule tyrosine kinase inhibitor with severe hepatotoxicity. It undergoes metabolism mainly by CYP3A4 to generate active metabolites regorafenib‐ N ‐oxide (M2) and ‐desmethyl‐regorafenib‐ (M5). Wuzhi capsule (WZC) an herbal preparation derived from Schisandra sphenanthera potentially used prevent regorafenib‐induced This study aims explore the effect of WZC on pharmacokinetics regorafenib in rats. An efficient sensitive liquid chromatography‐tandem mass spectrometry...
