Objective:To investigate the clinical efficacy of extended hepatectomy for hilar cholangiocarcinoma (HCCA) of Bismuth-Cor-lette typesⅢandⅣ(the longitudinal invasion degree along the biliary system is the main criteria). Methods:The clinical data of 61 patients with HCCA of Bismuth-Corlette types III and IV admitted in the Department of Hepatobiliary Surgery of the First Affiliated Hos-pital of Bengbu Medical College from January 2008 to May 2015 were analyzed retrospectively. Among the 61 cases, 22 underwent hepatectomy with half or over half of the liver removed or hepatic caudate lobectomy (regarded as the extended hepatectomy group), whereas 39 cases underwent irregular hepatectomy on the hepatic hilar region (regarded as the limited hepatectomy group). Results:Compared with those in the limited hepatectomy group, the patients in the extended hepatectomy group underwent longer duration of operation and experienced more bleeding during the procedure. The complication incidence rate for the extended hepatectomy group was lower than that for the limited hepatectomy group. No patient died during the perioperative period in the extended hepa-tectomy group, whereas two patients died in the limited hepatectomy group. Moreover, R0 resection was performed on 21 cases in the extended hepatectomy group, with a resection rate of (21/22) 95.5%, and on 20 cases in the limited hepatectomy group (P<0.05), with a resection rate of (20/39) 51.3%. Actuarial 1-, 3-, and 5-year survival rates were 77.27%, 36.36%, and 13.64%, respectively, in the extended hepatectomy group, and 69.23%, 20.51%, and 1.64%, respectively, in the limited hepatectomy group (P<0.05). Conclusion:Extended hepatectomy for patients with HCCA of Bismuth-Corlette typesⅢandⅣcould effectively increase the resection rates of R0 and the survival rate. Meanwhile, the prognosis of patients could be improved.

Protein phosphorylation is a ubiquitous protein post-translational modification, which plays an important role in cellular signaling systems underlying various physiological and pathological processes. Current in silico methods mainly focused on the prediction of phosphorylation sites, but rare methods considered whether a phosphorylation site is functional or not. Since functional phosphorylation sites are more valuable for further experimental research and a proportion of phosphorylation sites have no direct functional effects, the prediction of functional phosphorylation sites is quite necessary for this research area. Previous studies have shown that functional phosphorylation sites are more conserved than non-functional phosphorylation sites in evolution. Thus, in our method, we developed a web server by integrating existing phosphorylation site prediction methods, as well as both absolute and relative evolutionary conservation scores to predict the most likely functional phosphorylation sites. Using our method, we predicted the most likely functional sites of the human, rat and mouse proteomes and built a database for the predicted sites. By the analysis of overall prediction results, we demonstrated that protein phosphorylation plays an important role in all the enriched KEGG pathways. By the analysis of protein-specific prediction results, we demonstrated the usefulness of our method for individual protein studies. Our method would help to characterize the most likely functional phosphorylation sites for further studies in this research area.

Single amino acid polymorphisms (SAPs), also known as non-synonymous single nucleotide polymorphisms (nsSNPs), are responsible for most of human genetic diseases. Discriminate the deleterious SAPs from neutral ones can help identify the disease genes and understand the mechanism of diseases. In this work, a method of deleterious SAP prediction at system level was established. Unlike most existing methods, our method not only considers the sequence and structure information, but also the network information. The integration of network information can improve the performance of deleterious SAP prediction. To make our method available to the public, we developed SySAP (a System-level predictor of deleterious Single Amino acid Polymorphisms), an easy-to-use and high accurate web server. SySAP is freely available at http://www.biosino.org/ SySAP/ and http://lifecenter.sgst.cn/SySAP/.

Objective To study the role of leucine rich repeat neuronal 3 (LRRN3) in the prolif-eration of non-small cell lung cancer and its possible mechanism of expression regulation. Methods The expression of LRRN3 in non-small cell lung cancer was detected by real-time quantitative polymerase chain reaction ( qPCR) , immunohistochemistry and bioinformatics retrieval;A lung cancer cell line A549-LRRN3 with stable over-expression of LRRN3 was established by lentivirus over-expression technology;The effect of LRRN3 on the proliferation of non-small cell lung cancer was detected by methyl thiazolyl tetrazolium ( MTT) assay;Bioinformatics search for changes in methylation of LRRN3 promoter region and treatment of lung cancer cells by methyltransferase inhibitors to detect the effect of methylation on the regulation of LR-RN3 expression; Finally, bioinformatics search analyzes the correlation between LRRN3 and lung cancer prognosis. Results The mRNA expression of LRRN3 in clinical tissues of non-small cell lung cancer (n=12) was significantly lower than that of adjacent normal tissues (n=12) (P=0. 0014). The results of immunohistochemistry showed that the protein expression level of LRRN3 in non-small cell lung adenocar-cinoma was lower than that in normal tissues (P=0. 001), and the expression in non-small cell lung squa-mous cell carcinoma was also lower than that in normal tissues (P=0. 003). Overexpression of LRRN3 in-hibited the proliferation of tumor cells (P<0. 01), and the hypermethylation of LRRN3 in the promoter re-gion inhibited its transcriptional expression. LRRN3 was positively correlated with the survival prognosis of lung adenocarcinoma (P=5. 2e-09;HR=0. 48). Conclusions Hypermethylation in the promoter region of LRRN3 inhibits its transcriptional expression, thereby promoting the proliferation of lung cancer cells.
