Abstract
Background Cholangiocarcinoma (CCA) is a subtype of highly malignant hepatic tumor, which has low 5-year survival rate and poor clinical outcome. Only a few patients can be detected early and accepted with the surgery. Most of CCA patients are diagnosed in advanced stage, and the treatments are limited. As for the inoperable, advanced CCA patients, chemotherapy is the main treatment, due to lacking molecular targets, therapeutic effect is limited. Materials and methods To explore potential therapeutic targets for CCA, we analyzed three microarray datasets derived from the Gene Expression Omnibus (GEO) database. Then, we used GEO2R tools of NCBI to discover the differentially expressed genes (DEGs) from the CCA and normal liver tumor microarrays (TMA). Subsequently, we used the Database for Annotation, Visualization and Integrated Discovery (DAVID GO) to perform the Gene Ontology function (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Then, we carried out the Cytoscape software to search for the hub genes downregulated in CCA and identify the protein–protein interaction (PPI) of these genes. Besides, we used the GEPIA tool to evaluate the differential expressions of hub genes in CCA patients. Then, we also used MEXPRESS database to detect the promoter methylation levels of hub genes in CCA and normal tissue samples. In addition, we evaluated the expression of these genes in CCA lines and normal bile tract cells after 5-AZA (DNA methyltransferase inhibitor) treatment. Results A total of 115 downregulated DEGs were identified. Among them, 10 hub genes with a high degree of connectivity were picked out. Among these 10 hub genes, F2, AHSG, ALDH8A1, SERPIND1 and AGXT showed higher DNA methylation levels of promoter in CCA compared with normal liver tissues. Therefore, these 5 genes may be the potential DNA methylation biomarkers and therapeutic targets in CCA.

Abstract
In patients with liver disease at risk of pulmonary oedema, cryoprecipitate (small volume) might be a viable alternative to fresh frozen plasma (FFP, large volume) in the correction of coagulopathy. However, the efficacy of cryoprecipitate in these patients has not been tested. We evaluated the role of cryoprecipitate in the correction of the coagulopathy of liver disease. To establish initial evidence of efficacy, six consecutive patients with hepatic failure and coagulopathy received five units of cryoprecipitate. Then, using a crossover design, 11 consecutive patients were randomized to receive either four units of FFP or five units of cryoprecipitate. Pre and post infusion International Normalized Ratio (INR), activated Partial Thromboplastin Time (aPTT), fibrinogen D-dimers, Factors V and IX, and reptilase time were measured. In the first six patients, cryoprecipitate improved the INR, aPTT and fibrinogen concentration (P = 0.03). In the crossover study, FFP administration produced a greater improvement in INR (P = 0.007) and aPTT (P = 0.005) than cryoprecipitate. However, there were no differences in any of the other measured variables. One patient developed acute pulmonary oedema while receiving FFP. Cryoprecipitate improves the coagulopathy of liver disease. Four units of FFP are more efficacious than five units of cryoprecipitate. Cryoprecipitate may have a role in correction of the coagulopathy associated with liver disease where concerns about pulmonary oedema exist.
