Furthermore, immunohistochemistry (IHC) was conducted to assess the expression levels of KIF20A in patients included from our center. The prognostic value of KIF20A for disease-free survival (DFS) and overall survival (OS) was further evaluated using Cox regression analysis.Results: According to the results obtained from online tools, it was found that patients with low KIF20A expression exhibited significantly better survival outcomes in terms of relapse-free survival (RFS), distant metastasis-free survival (DMFS), and OS compared to those with high KIF20A expression (P < 0.001, P < 0.001, and P = 0.008, respectively). Additionally, significantly lower gene expression of KIF20A was found in patients who respon

More than 10 deposits have been discovered in this major orefield of the middle/lower Yangtze valley Fe-Cu-S-Au metallogenic belt. The field has undergone a very long tectonic evolution, from basement formation through stable deposition to intraplate deformation. The ore-forming process resulted from the superimposition of Yanshanian magmatic activity on the Palaeozoic-Triassic sedimentary formation and was conditioned by a variety of factors, showing both endogenic and exogenic characteristics. Deposit types include hydrothermal, skarn, stratabound skarn and porphyry, with a distinct vein-pipe-strata-porphyry sequence of mineralisation in which stratiform mineralisation is the most important. Such multi-layered series of ores are typical of the Tongling area and have some prospecting significance throughout the middle and lower Yangtze valley., More than 10 deposits have been discovered in this major orefield of the middle/lower Yangtze valley Fe-Cu-S-Au metallogenic belt.
