RESUMEN
Seeking an effective and safe scheme is the common goal of clinical treatment of tumor patients. In recent years, traditional Chinese medicine has attracted more and more attention in order to discover new drugs with good anti-tumor effects. Oroxylin A (OA) is a compound found in natural Oroxylum indicum and Scutellaria baicalensis Georgi plants and has been used in the treatment of various cancers. Studies have shown that OA has a wide range of powerful biological activities and plays an important role in neuroprotection, anti-inflammation, anti-virus, anti-allergy, anti-tumor and so on. OA shows high efficacy in tumor treatment. Therefore, it has attracted great attention of researchers all over the world. This review aims to discuss the anti-tumor effects of OA from the aspects of cell cycle arrest, induction of cell proliferation and apoptosis, induction of autophagy, anti-inflammation, inhibition of glycolysis, angiogenesis, invasion, metastasis and reversal of drug resistance. In addition, the safety and toxicity of the compound were also discussed. As a next step, to clarify the benefits and adverse effects of Oroxylin A in cancer patients further experiments, especially clinical trials, are needed.

Background: Thyroid hormone receptor-associated protein 3 (THRAP3) is of great significance in DNA damage response, pre-mRNA processing, and nuclear export. However, the biological activities of THRAP3 in pan-cancer remain unexplored. We aimed to conduct a comprehensive analysis of THRAP3 and validate its expression levels in lung cancer. Methods: A pan-cancer analysis was conducted to study the correlation of THRAP3 expression with clinical outcome and the tumor microenvironment based on the available bioinformatics databases. The protein levels of THRAP3 were explored in lung cancer by immunohistochemistry (IHC) analysis. Single-cell sequencing (ScRNA-seq) analysis was employed to investigate the proportions of each cell type in lung adenocarcinoma (LUAD) and adjacent normal tissues, along with the expression levels of THRAP3 within each cell type. Results: THRAP3 is upregulated in multiple cancer types but exhibits low expression in lung squamous cell carcinoma (LUSC). immunohistochemistry results showed that THRAP3 is a lowly expression in LUAD and LUSC. THRAP3 elevation had a poor prognosis in kidney renal clear cell carcinoma and a prolonged survival time in kidney chromophobe, brain lower-grade glioma and skin cutaneous melanoma, as indicated by the KM curve. Single-cell analysis confirmed that the proportions of T/B cells, macrophages, and fibroblasts were significantly elevated in LUAD tissues, and THRAP3 is specifically overexpressed in mast cells. Conclusion: Our findings uncover that THRAP3 is a promising prognostic biomarker and immunotherapeutic target in multiple cancers, but in LUAD and LUSC, it may be a protective gene.
RESUMEN
OBJECTIVE: To assess the clinical efficacy of microwave ablation (MWA) in treating tumour patients with postsurgical intrapulmonary oligometastases or oligorecurrence (PIORO). STUDY DESIGN: Descriptive study. Place and Duration of the Study: Departments of Thoracic Surgery and Oncology, Jinan Central Hospital and Qilu Hospital, Jinan, China, from January 2014 to June 2023. METHODOLOGY: Clinical data of 31 patients with PIORO receiving treatment with MWA were retrospectively analysed. After undergoing MWA, the patients were followed up for computed tomography (CT) examination on the 7th day, 1st month, and every 3 months, respectively. The Kaplan-Meier method was conducted to evaluate the clinical outcomes; overall survival (OS), progression-free survival (PFS), and time to local progression (TTLP). RESULTS: All patients with PIORO were successfully treated with MWA. The 3-year survival rate of patients was 35.5%. The median OS was 26.0 months, the median PFS was 11.1 months, and the median TTLP was 14.4 months. Patients with oligometastatic or oligorecurrent tumours ≤3 cm in diameter showed better PFS (≤3 cm, 14.261 m vs. >3 cm, 7.786 m; p <0.01) and TTLP (≤3 cm, 19.522 m vs. >3 cm, 12.214 m; p <0.05) than those with tumours >3 cm in diameter. Clinical characteristics of the patients were not significantly correlated with OS. CONCLUSION: MWA, as a topically therapeutic method, is an effective procedure for tumour patients with PIORO, especially in cases of oligometastatic or oligorecurrent tumours ≤3 cm in diameter.
