A 5-year-old Russian blue cat was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with the history of anorexia, lethargy, weight loss(6.5 to 4.8 kg) 2 weeks ago. Abdominal ultrasonography showed the following : increase of echogenicity of liver, irregular shape of gall bladder, hyperechoic region around duodenum. Pancreatitis, cholangitis, hepatic lipidosis was diagnosed by the ultrasonography. Anti- inflammatory therapy, antibiotic therapy was administered. Abdominal ultrasonography is a efficient available diagnostic tool but serum fPL test reveals the highest sensitivity and specifity result for feline pancreatitis. SNAP fPL test is newly released that can check pancreatitis within 10 minutes by same princple of Spec fPL test used in Gastrointestinal Laboratory of Texas A & M Univerrsity.

This study was performed to evaluate the anticancer, antioxidant, and antimicrobial activities of fractions and isolated compounds from anemone (Anemone cathayensis). Fourteen compounds were isolated from extracts. Anticancer activities of fractions and compounds were determined by MTT assay, and all tested fractions showed inhibition activity on human breast cancer cells (MDA-MB-231). The fraction 6 displayed the strongest anticancer activity, and inhibition percent was 50.32%. The antioxidant effect of fractions was evaluated by using DPPH scavenging assays. Fraction 5 had a higher DPPH radical scavenging activity with low IC50 value of 30.578μg/mL. The antimicrobial activity of the fractions was evaluated against 3 microorganisms using the agar well diffusion method. The fractions also showed moderate antimicrobial activity. These results suggest that anemone could hold a good potential source for human health.

Objective: This work aimed to evaluate the safety and clinical efficacy of transcatheter arterial chemoembolization (TACE) combined with c-arm cone-beam CT guided synchronous radiofrequency ablation (RFA) in treatment of large hepatocellular carcinoma (HCC). Methods: 21 patients with large HCC were studied from January 2010 to March 2012. TACE combined with synchronous C-arm cone-beam CT guided RFA were performed on a total of 25 lesions. Conventional imaging examination (CEUS, enhanced CT or MRI) and AFP detection were regularly conducted to evaluate the technical success rate of combined treatment, complications, treatment response, time without disease recurrence and survival rate. Results: The technical success rate of combined treatment was 100%, without any significant complication. After 1 month, there were 19 cases with complete response and 2 cases with partial response, with an complete response rate of 90.4% (19/21) and a clinical effective rate of 100% (21/21). The complete response rates of single nodular lesions (100%, 17/17) was significantly higher than that of multiple nodular lesions (50%, 2/4) (P<0. 05). During 2 to 28 months of follow-up, in 19 cases with complete response, the average time without disease recurrence was $10.8{\pm}6$ months. The total survival rates of 6, 12 and 18 months in 21 patients were 100%, respectively. Conclusion: TACE combined with synchronous C-arm CT guided RFA is safe and effective for treatment of large HCC. The treatment efficacy for single nodular lesion is better than that for multiple nodular lesions.

Genetic epidemiological studies have shown that genetic susceptibility to esophageal cancer (EC) is an important cause of its high incidence within families in some areas of China. The purpose of this study was to obtain evidence of a genetic basis of EC in Xin-an and Xin-xiang counties in China. Familial aggregation and complex segregation analyses were performed of 79 EC families in these counties. The heritability of EC was examined using Falconer's method and complex segregation analysis was conducted with the SEGREG program in Statistical Analysis for Genetic Epidemiology (SAGE version 5.3.1). The results showed that the distribution of EC in families did not fit well into a binomial distribution. The heritability of EC among first-degree and second-degree relatives was $67.0{\pm}7.31%$ and $43.1%{\pm}9.80%$, respectively, and the summing up powered heritability was $53.2{\pm}6.74%$. The segregation ratio was 0.045. Complex segregation analysis showed that the genetic model of EC was additive. The current results provide evidence for an inherited propensity to EC in certain high-risk groups in China, and support efforts to identify the genes that confer susceptibility to this disease.

Aims: The treatment responses of advanced hepatocellular carcinoma( HCC) with portal vein tumor thrombosis(PVTT) were not acceptable and treatment modalities were limited. So, we compared effects and safety of sorafenib vs. hepatic arterial infusion chemotherapy( HAIC). Methods: We prospectively collected data of 58 advanced HCC with PVTT patients whose Child-Turcotte-Pugh(CTP) score range 5 to 7 in 6 university hospitals from January 2013 to Oct 2015. Each twenty nine patients were treated with sorafenib or HAIC. Results: 1. The mean age was 60.2±8.4 years old and 89.7% of the patients were male. Causes of HCC were HBV (67.3%), HCV (8.6%), alcohol (19.0%) and others (5.2%). CTP class A was 89.7%, modified Union for International Cancer Control (mUICC) stage IVa was 63.8%, tumor diameter >10cm was 55.2%, multiple tumor was 60.3%, infiltrative type was 56.9%, main PVTT was 63.8%, median AFP value was 240.4 ng/ml. 2. 29 patients were enrolled to each groups. Baseline characteristics( sex, mean age, cause of HCC, mUICC stage, size of tumor, number of tumor, type of tumor(nodular, massive, infiltrative, diffuse), location of PVTT(main, main+branch, branch). CTP class, median value of AFP) has no significant difference between two groups. 3. The objective response rate was 38.1% in HAIC and 4.5% in sorafenib group (p=0.003). In univariate analysis, treatment modality, main portal vein invasion, objective response, massive tumor type were significant prognostic factors of overall survival (p=0.012, 0.046, 0.011, 0.041) and treatment modality, tumor number, massive tumor type were significant prognostic factors of time to progress (p=0.004, 0.043, <0.01). In multivariate analysis, objective response was a significant prognostic factor of overall survival (p=0.048) and treatment modality was a significant prognostic factor of time to progress (p=0.016). 4. Major complications were neutropenia (6.9%, more than grade 3) and catheter-related complication (3.4%) in HAIC group, hand-foot syndrome (20.7%) and diarrhea (3.4%) in sorafenib group. Conclusions: For treatment of advanced HCC with PVTT patient, HAIC can be a valuable treatment modality like as sorafenib and more large size of study is needed.

Polymorphisms in miRNA binding sites have been shown to affect miRNA binding to target genes, resulting in differential mRNA and protein expression and susceptibility to common diseases. Our purpose was to predict SNPs (single nucleotide polymorphisms) within miRNA binding sites of inflammatory genes in relation to gastric cancer. A complete list of SNPs in the 3'UTR regions of all inflammatory genes associated with gastric cancer was obtained from Pubmed. miRNA target prediction databases (MirSNP, Targetscan Human 6.2, PolymiRTS 3.0, miRNASNP 2.0, and Patrocles) were used to predict miRNA target sites. There were 99 SNPs with MAF>0.05 within the miRNA binding sites of 41 genes among 72 inflammation-related genes associated with gastric cancer. NF-${\kappa}B$ and JAK-STAT are the two most important signaling pathways. 47 SNPs of 25 genes with 95 miRNAs were predicted. CCL2 and IL1F5 were found to be the shared target genes of hsa-miRNA-624-3p. Bioinformatic methods could identify a set of SNPs within miRNA binding sites of inflammatory genes, and provide data and direction for subsequent functional verification research.

Purpose: Four polymorphisms, -765G>C, -1195G>A, 8473T>C, and Val511Ala, in the cyclooxygenase-2 (COX-2) gene were identified to be associated with colorectal cancer (CRC) risk. However, the results are inconsistent. The objective of this meta-analysis was to evaluate the association between these four polymorphisms and the risk of CRC. Materials and Methods: All eligible case-control studies published up to December 2012 on the association between the four polymorphisms of COX-2 and CRC risk were identified by searching PubMed and Web of Science. The CRC risk associated with the four polymorphisms of the COX-2 gene was estimated for each study by odds ratio (OR) together with its 95% confidence interval (CI), respectively. Results: A total of 15 case-control studies were included. Overall, no evidence has indicated that the -1195A allele, -765C allele, 8473C allele, and 511Ala allele are associated with susceptibility to CRC (-1195G>A: OR=1.11, 95% CI: 0.82-1.51, p=0.78; -765G>C: OR=1.08, 95% CI: 0.96-1.21, p=0.07; 8473T>C: OR=1.03, 95% CI: 0.89-1.18, p=0.91; Val511Ala:OR=0.71, 95% CI: 0.46-1.09, p=0.94). However, stratified analysis with ethnicity indicated that individuals with -765GC or GC/CC genotypes had an increased risk of CRC among Asian populations (GC vs. GG: OR=1.05, 95% CI: 0.87-1.28, p=0.03; GC+CC vs. GG: OR=1.08, 95% CI: 0.96-1.21, p=0.07). Conclusion: This meta-analysis indicated that -765G>C polymorphism was significantly associated with susceptibility to CRC in Asian populations.

A moderately halophilic bacterial strain 15-13^T, which was isolated from soda meadow saline soil in Daqing City, Heilongjiang Province, China, was subjected to a polyphasic taxonomic study. The cells of strain 15-13^T were found to be Gram-negative, rod-shaped, and motile. The required growth conditions for strain 15-13^T were: 1-23% NaCl (optimum, 7%), 10-50°C (optimum, 35°C), and pH 7.0-11.0 (optimum, pH 9.5). The predominant cellular fatty acids were C18:1 ω7c (60.48%) and C16:0 (13.96%). The DNA G+C content was 67.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons indicated that strain 15-13^T clustered within a branch comprising species of the genus Halomonas. The closest phylogenetic neighbor of strain 15-13^T was Halomonas pantelleriensis DSM 9661^T (98.9% 16S rRNA gene sequence similarity). The level of DNA-DNA relatedness between the novel isolated strain and H. pantelleriensis DSM 9661^T was 33.8%. On the basis of the phenotypic and phylogenetic data, strain 15-13^T represents a novel species of the genus Halomonas, for which the name Halomonas alkalitolerans sp. nov. is proposed. The type strain for this novel species is 15-13^T (=CGMCC 1.9129^T =NBRC 106539^T).
