Abstract
Gallbladder occupying lesions are common diseases of biliary system. Among them, gallbladder cancer is difficult to diagnose due to the indistinguishable early symptoms, thus posing a great risk to the population. This study aims to establish a computed tomography (CT) prediction model for distinguishing benign and malignant lesions of gallbladder occupying lesions.The study included 211 patients with benign or malignant gallbladder occupying lesions who have taken resection in the Nanjing Drum Tower Hospital from January 2009 to December 2017. Clinical data collected includes age and sex; CT data includes tumor location, tumor maximum diameter, tumor form, venous phase portal venous CT value, abdominal aortic CT value, plain phase CT value, arterial phase CT value, venous phase CT value, delayed phase CT value, ΔCT1, ΔCT2, ΔCT3, ΔCT4, ΔCT5, ΔCT6, and ΔCT7. Calculation of odds ratio between benign and malignant gallbladder occupying lesions using single factor screening variables and multivariate logistic regression was done to establish a model and calculate the areas under receiver operating characteristic curves of the model.Multivariate logistic regression analysis showed that age, tumor maximum diameter, tumor form, venous phase portal venous CT value, ΔCT2, ΔCT4, and ΔCT6 are the main characteristic index for differential diagnosis of benign and malignant risk of gallbladder occupying lesions.Patients' age, tumor maximum diameter, tumor form, venous phase portal venous CT value, ΔCT2, ΔCT4, and ΔCT6 are independent risk factors for judging the benign and malignant of gallbladder occupying lesions. The model established exhibited a potential diagnostic value for distinguishing the malignant properties of gallbladder occupying lesions.

Abstract
BACKGROUND PIM1, a serine/threonine kinase, plays an essential role in tumorigenesis of multiple types of tumors. However, the expression pattern and functions of PIM1 in gallbladder cancer (GBC) remain largely unknown. MATERIALS AND METHODS Immunohistochemistry, quantitative real-time PCR, and western blot analysis were performed to measure the expression of PIM1. Tissue microarray analysis was used to confirm the relationship between PIM1 expression and clinical outcomes of GBC patients. Finally, in vivo and in vitro functional studies were performed to detect the inhibition of PIM1 by RNAi or specific inhibitor in GBC cells. RESULTS We observed that PIM1 was dramatically overexpressed in GBC tissues, and its expression levels were positively related with clinical malignancies and a poor prognosis. Inhibition of PIM1 via RNAi or enzyme-specific inhibitor could suppress GBC cell proliferation, migration, and invasion both in vitro and vivo. Additionally, flow cytometry assays and cell cycle assays indicated that PIM1 inhibition promoted cell apoptosis and induced cell cycle arrest. Remarkably, inhibition of PIM1 could drive a metabolic shift from aerobic glycolysis to oxidative phosphorylation. We found that inhibition of PIM1 mechanistically reduced glucose consumption by regulating key molecules in aerobic glycolysis. CONCLUSION PIM1 may serve as an oncogene in GBC and be involved in the regulation of glycolysis. PIM1 is a promising therapeutic target for the treatment of human GBC.

Abstract
Background Gallbladder cancer (GBC) is a highly lethal disease and the most common biliary tract malignant tumor with poor prognosis. Accumulating evidence indicates that cluster of differentiation 44 (CD44) is overexpressed in several malignancies and has a crucial role in the development of cancer. However, its expression and function in GBC are unclear. The aim of this study was to explore CD44 expression and its role in GBC. Materials and methods The expression of CD44 was measured by immunohistochemistry. Tissue microarray analysis was used to confirm the relationship between CD44 expression and clinical outcomes of GBC patients. EDU assay, colony formation assay, cell migration and invasion assay were performed to detect the functions of CD44 in GBC-SD and NOZ transfected with si-RNA. Results CD44 was overexpressed and associated with poor outcomes in GBC patients. The univariate and multivariate analyses confirmed that elevated CD44 was an independent prognostic factor for the OS of GBC patients. Silencing CD44 could suppress the GBC cell proliferation, migration and invasion in vitro, as well as attenuated cancer stem cell functions. Conclusion CD44 markedly correlated with aggressive tumor behaviors and contributed to the progression of GBC, which could represent a novel prognostic marker and potential therapeutic target for GBC patients.
