Background: The LigaSure vessel sealing system has been proposed to save operation time and reduce intraoperative blood loss for various surgeries. However, its usage for gastric cancer is still controversial. The aim of the present meta-analysis was to compare the effectiveness of LigaSure with conventional surgery in gastrectomy. Materials and Methods: Sources were retrieved from the Cochrane Library, MEDLINE, EMBASE, SCOPUS and Google Scholar until February, 2015. All randomized controlled trials comparing LigaSure with conventional surgery in curative gastric cancer resection were selected. After data extraction, statistics were performed by Review Manager 5.1 software. Results: Three eligible randomized controlled trials were evaluated, with a total of 335 patients. The quality of the included trials was good, yet some methodological and clinical heterogeneity existed. There were no significant differences between the LigaSure and conventional groups in operative time (weighted mean difference [WMD], -22.95 minutes; 95% confidence interval [CI], [-59.75, 13.85]; P = 0.22), blood loss (WMD, -45.8 ml; 95% CI, [-134.5, 42.90]; P = 0.31), nor the incidence of surgical complications (odds ratio, 1.18; 95% CI, [0.68, 2.05]; P = 0.54). But there was a longer duration of hospital stay in LigaSure group (WMD, 1.41 days; 95% CI, [0.14, 2.68]; P = 0.03). Conclusions: All available randomized evidence has been summarized. LigaSure does not confer significant advantage over conventional surgery for curative gastric cancer resection. The usefulness of the device may be limited in gastrectomy. But, more trials are needed for further assessment of the LigaSure system for gastric cancer.

Canonical transient receptor potential channels(TRPCs) are nonselective, high calcium permeability cationicchannels. The TRPCs family includes TRPC1, TRPC2,TRPC3, TRPC4, TRPC5, TRPC6, and TRPC7. These channelsare widely expressed in the cardiovascular and nervoussystems and exist in many other human tissues and celltypes, playing several crucial roles in the human physiologicaland pathological processes. Hence, the emergenceof TRPCs modulators can help investigate these channels’applications in health and disease. It is worth noting that theTRPCs subfamilies have structural and functional similarities,which presents a signifi cant diffi culty in screening anddiscovering of TRPCs modulators. In the past few years,only a limited number of selective modulators of TRPCswere detected; thus, additional research on more potent andmore selective TRPCs modulators is needed. The presentreview focuses on the striking desired therapeutic eff ectsof TRPCs modulators, which provides intel on the structuralmodifi cation of TRPCs modulators and further pharmacologicalresearch. Importantly, TRPCs modulators cansignifi cantly facilitate future studies of TRPCs and TRPCsrelated diseases.

Serum alpha-fetoprotein (AFP) is a significant marker for clinical diagnosis and prognosis evaluation in hepatocellular carcinoma (HCC) patients. However, some proportion of liver cancer patients are AFP-negative (AFP ${\leq}$20ng/ml). In order to study the differences between clinicopathological factors and prognosis of alpha-fetoprotein negative and positive patients, a total of 114 cases (41 AFP-negative and 73 AFP-positive) were selected for our research. By systematically statistical analysis, the results demonstrated that compared with AFP-negative patients, AFP-positive examples were more likely to feature cirrhosis nodules, non-complete neoplasm capsules, and a poor Edmondson-steiner grade. Furthermore, AFP-negative patients demonstrated a favorable long-term prognosis. By univariate analysis and multivariate analysis with Cox's proportional hazards model, multiple tumors were found to be independent risk factors for worse survival of AFP negative patients; however, less tumor-free margins, multiple tumors and Edmondson-steiner grades III/IV, proved to be independent risk factors leading to a poor prognosis of AFP positive cases. Finally, we can infer that high levels of AFP signify a highly malignant tumor and unfavorable prognosis.

Purpose: To compare differentially expressed genes (DEGs) mediating osteoarthritis (OA) in knee cartilage and in normal kneecartilage in a rat model of OA and to identify their impact on molecular pathways associated with OA. Materials and Methods: A gene expression profile was downloaded from the Gene Expression Omnibus database. Analysis ofDEGs was carried out using GEO2R. Enrichment analyses were performed on the Gene Ontology (GO) and Kyoto Encyclopedia ofGenes and Genomes pathway using the Search Tool for the Retrieval of Interacting Genes database (http://www.string-db.org/). Subsequently, the regulatory interaction network of OA-associated genes was visualized using Cytoscape software (version 3.4.0;www.cytoscape.org). Results: In the gene expression profile GSE103416, a total of 99 DEGs were identified. Among them, 76 DEGs (76.77%) were overexpressed,and the remaining 23 DEGs (23.23%) were underexpressed. GO and pathway enrichment analyses of target geneswere performed. Using gene-gene interaction network analysis, relevant core genes, including MET, UBB, GNAI3, and GNA13,were shown to hold a potential relationship with the development of OA in cartilage. Using quantitative real-time PCR, the Gna13/cGMP-PKG signaling pathway was identified as a potential research target for therapy and for further understanding the developmentof OA. Conclusion: The results of the present study provide a comprehensive understanding of the roles of DEGs in knee cartilage in relationto the development of OA.
