Establishment and evaluation of risk prediction model for the esophageal cancer via whole transcriptome analysis / 中国胸心血管外科临床杂志

@#Objective    To establish the gene-based esophageal cancer (ESCA) risk score prediction models via whole transcriptome analysis to provide ideas and basis for improving ESCA treatment strategies and patient prognosis. Methods    RNA sequencing data of esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC) and adjacent tissues were obtained from The Cancer Genome Atlas database. The edgeR method was used to screen out the differential genes between ESCA tissue and normal tissue, and the key genes affecting the survival status of ESCC and EAC patients were initially identified through univariate Cox regression analysis. The least absolute shrinkage and selection operator regression analysis and multivariate Cox regression analysis were used to further screen genes and establish ESCC and EAC risk score prediction models. Results    The risk score prediction models were the independent prognostic factors for ESCA, and the risk score was significantly related to the survival status of patients. In ESCC, the risk score was related to T stage. In EAC, the risk score was related to lymph node metastasis, distant metastasis and clinical stage. The constructed nomogram based on risk score showed good predictive ability. In ESCC, the risk score was related to tumor immune cell infiltration and the expression of immune checkpoint genes. However, this feature was not obvious in EAC. Conclusion 聽 聽The ESCC and EAC risk score prediction models have shown good predictive capabilities, which provide certain inspiration and basis for optimizing the management of ESCA and improving the prognosis of patients.

Research progress in the treatment of traumatic hemothorax / 中华胸心血管外科杂志

Traumatic hemothorax is a common disease in chest trauma .If it is not treated properly and effectively , it will lead to continuous blood loss, clotted hemothorax, empyema and other life-threatening conditions.Because of no universally ac-cepted guide or consensus in the treatment of traumatic hemothorax , clinicians often choose different ways to treat different de-grees and types of traumatic hemothorax according to their habits and experience .This article focus on recent studies on the treatment of traumatic hemothorax , summarize the latest achievements in the field of traumatic hemothorax , provide evidence for clinicians'clinical decision-making, and find the current insufficiency of traumatic hemothorax and the direction for further re-search.
