Means: The GSE17674 dataset was selected for analysis, obtained by data retrieval based on the GEO public database. The R language limma toolkit was used to screen DEmRNAs. After the data were normalized, the Metascape online analysis software and the R language clusterProfiler package were used to analyze the GO function and KEGG pathway enrichment of DEmRNAs lines, respectively. The string database was selected for PPI analysis, and the results were imported into Cytoscape software to derive the core modules and predicted core genes. The genes selected above were analyzed for tissue localization specificity. Results: Through the analysis of GSE17674, differentially expressed genes were screened out, and GO and KEGG analyses were performed on the differentially expressed genes. The GO functional enrichment analysis was mainly enriched in the process of muscle system, muscle contraction, myocyte development, contractile fibers, myogenic fibers, myofibers, myofibrillar segments, actin binding, structural composition of muscle, and actin filament binding. KEGG pathway analysis showed that the core pathways associated with the development of ES were the core genes for myocardial contraction, congestive cardiomyopathy, and hypertrophic cardiomyopathy. Five Hub genes were obtained based on Cytoscape prediction. Tissue localization specificity analysis of Hub genes was performed, and a total of 2 Hub genes with tissue specificity were screened;MYH6 was specifically expressed in cardiac cells and MYL1 was specifically expressed in skeletal muscle cells. Conclusions: The differential genes screened will help to understand the molecular mechanisms underlying the highly invasive and metastasis-prone biological characteristics of ES, as well as provide new ideas for clinical drug-targeted treatment of ES.展开更多

Renal tumors during pregnancy are uncommon, with renal cell carcinoma being the most frequent. The diagnosis of cancer during pregnancy has increased due to the use of non-invasive prenatal testing (NIPT) and advanced maternal age. Renal tumors, such as Ewing’s sarcoma, present a diagnostic and therapeutic challenge due to the physiological changes during pregnancy. Renal Ewing’s sarcoma is aggressive and tends to manifest with abdominal pain, a palpable mass, and severe hematuria. However, its symptoms often go unnoticed, leading to late diagnosis with distant metastasis and poor prognosis. This type of tumor is diagnosed through histopathological studies, as imaging alone is insufficient for its characterization. In the presented case, multiparametric magnetic resonance imaging (MP-MRI) was used to assess the renal mass due to the limitations of using computed tomography in pregnant women. MRI provides both morphological and behavioral information about the tumor and is particularly useful in patients where radiation exposure is contraindicated. In this case, the MRI revealed a large tumor in the left kidney, with extension to adjacent structures, thrombosis in the vena cava, and hepatic and bone metastases. The article concludes that this is the largest renal Ewing’s sarcoma tumor described in a pregnant patient in the literature. It highlights the importance of early diagnosis and appropriate intervention to improve the prognosis in these rare but aggressive cases.展开更多
