Objective To study the relationship between HAI and HBsAg, HCV in HCC, pericarcinomatous tissues. Methods The patterns of HBsAg and HCV in 100 cases of hepatocellular carcinoma(HCC) and their surrounding liver tissues were studied on paraffin-embeded sections with immunohistochemistry technique, and pericarcinomatous tissues were scored in Knodell’s histological activity index(HAI). Results The score of HAI in the group of co-infection of HBV, HCV is the highest in the four groups(12.62?3.88). The score of HAI in the group which is not infected by HBV, HCV is the lowest in the four groups(6.67?2.58). HBV, HCV virus infection were positively correlated with HAI(rs=0.39,P=0.0001). HBsAg and HCV were detected both in HCC and pericarcinomatous tissues. The positive rate of HBsAg in Pericarcinomatous Tissues(79%) was higher than that of in HCC tissues(23%). HCV expressions in HCC(15%) and pericarcinomatous tissues(23%) had no differences. Conclusions As for the tissues of liver cancer with virus infection background, the HAI is obviously higher than that without virus infection background. HBV, HCV virus infection were correlated with HAI significantly, perennial virusemia will aggravate pathological changes of liver tissue.

Objective To investigate the association between the Adiponectin rs266729 and rs2241766 gene polymorphisms and nonalcoholic fatty liver disease in the Han Chinese population residing in Qingdao. Methods Adiponectin rs266729 and rs2241766 gene polymorphisms were genotyped in patients with NAFLD (n = 336) and healthy controls (n = 280) using polymerase chain reaction (PCR). Serum lipid profiles and adiponectin levels were determined using biochemical methods. Statistical analyses were performed using Pearson Chi square test, logistic regression analysis, t test, linear regression analysis. Results We found a significant association between the Adiponectin rs266729 genotype frequencies and allele frequencies between NAFLD pa-tients and controls (χ2= 9.929, P = 0.007; χ2= 9.809, P = 0.002). After adjustment of confounding factor, the rs266729 G allele was associated with an increased risk of NAFLD compared to the C allele (OR = 1.410, 95%CI: 1.082-1.831, P = 0.008) No significant differences were found in the rs2241766 genotype frequencies and allele frequencies between NAFLD population and the controls (OR = 1.410, 95%CI: 1.082-1.831, P = 0.008). Conclusion The Han Chinese in Qingdao carrying the rs266729 G allele are at increased risk of NAFLD.

Currently the incidence of nonalcoholic fatty liver disease (NAFLD) is increasing, and the age of onset is getting younger worldwide, resulting in a heavy economic burden for both individuals and the society. Since NAFLD is closely related to heredity, metabolism, and the environment, genetic factors play an important role in the development and progression of NAFLD. With the development and wide application of the techniques from the genome-wide association studies, new research advances have been achieved in the susceptibility genes of NAFLD. This review summarizes the related research findings at home and abroad, and investigates the pathogenic factors for NAFLD and related mechanisms with a focus on the polymorphisms of susceptibility genes.

ObjectiveTo investigate the clinical features of cholestatic liver disease (CLD), and to provide a reference for strengthening the diagnosis and treatment of this disease. MethodsA retrospective analysis was performed for the clinical data of 107 patients who were admitted to Chenggong Hospital Affiliated to Xiamen University from January 2015 to December 2017 and were diagnosed with CLD. The t-test was used for comparison of continuous data between groups. ResultsMost patients had the clinical symptoms of weakness, loss of appetite, nausea, abdominal distension, pruritus, and jaundice. According to the site of cholestasis, there were 64 patients (59.8%) with intrahepatic cholestasis and 43 (40.2%) with extrahepatic cholestasis. The cause of the disease was common bile duct stones in 21 patients (19.6%), bile duct parasites in 1 patient (0.9%), primary sclerosing cholangitis in 2 patients (1.9%), primary biliary cirrhosis in 3 patients (2.8%), liver cancer in 8 patients (7.5%), bile duct carcinoma in 5 patients (4.7%), pancreatic cancer in 4 patients (3.7%), pancreatitis in 12 patients (11.2%), viral hepatitis in 28 patients (26.2%), drug-induced liver injury in 11 patients (10.3%), alcoholic hepatitis in 6 patients (5.6%), nonalcoholic fatty liver disease in 4 patients (3.7%), and autoimmune hepatitis in 2 patients (19%). The CLD patients with underlying diseases had a significantly poorer liver function (alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase, alkaline phosphatase, bile acid, and total bilirubin) than those with CLD alone (t=-3.44, -2.99, -2.42, -4.39, -3.34, and -2.49, all P＜0.05). Most of the patients achieved good recovery after liver-protecting, transaminase-lowering, and jaundice clearance treatment. The patients with tumors had poor prognosis. ConclusionCLD has various causes, and its clinical features lack specificity. Clinicians should pay enough attention to this disease.

Renal cell carcinoma (RCC), one of the most common kidney cancers, has a poor prognosis. Epithelial to mesenchymal transition (EMT) is a hallmark of carcinoma invasion and metastasis. Several studies have examined the molecular regulation of EMT, but the relationship between histone demethylases and EMT is little understood. In this study, we investigated the role of retinoblastoma-binding protein-2 (RBP2), a histone demethylase that is highly expressed in RCC and is positively correlated with poor RCC prognosis in the regulation of EMT. We found that ectopic overexpression of RBP2 can induce cancer stem cell-like (CSC) phenotypes through EMT in RCC cells by converting them to a more mesenchymal phenotype. This results in increased resistance to apoptosis, which leads to enhanced tumor growth in xenograft models. Together, our data show that RBP2 is an epigenetic regulator that has an important role in the initiation of CSC phenotypes through EMT, leading to tumor progression. RBP2 is also a novel biomolecule for RCC diagnosis, and prognosis and may be a therapeutic target.

OBJECTIVETo investigate the association between two polymorphisms of the APOC3 gene (T-455C and C-482T) and hereditary risk of non-alcoholic fatty liver disease (NAFLD).

METHODSA total of 287 patients with NAFLD and 310 control subjects were genotyped by PCR and direct sequencing. Serum lipid profiles were also detected by standard biochemical

METHODSOne-hundred-and-eighty of the study participants were used to measure the APOC3 content by enzyme-linked immunosorbent assay. Inter-group differences and associations were assessed statistically using Chi square and t tests and logistic and linear regression analyses.

RESULTSThe frequencies of neither the genotypes or alleles were significantly different between the NAFLD cases and the controls. Compared with the most common genotypes-455TT or-482CC, none of the variants showed a significant increase in risk of NAFLD or for the clinical and biochemical parameters. The adjusted odds ratios (with 95% confidence intervals) of NAFLD were 1.25 (0.79-1.96) and 1.20 (0.76-1.89) for carriers of the APOC3-455C and-482 T variants respectively (P more than 0.05).

CONCLUSIONThe T-455C and C-482T polymorphisms of the APOC3 gene are not associated with risk of NAFLD, pathogenic changes in lipid profiles, or insulin resistance in Han Chinese.

OBJECTIVETo investigate the association between the PNPLA3 rs738409 polymorphism and chronic hepatitis B (CH[B) in a Han Chinese population residing in Qingdao.

METHODSPeripheral blood samples were collected from 185 CHB patients and 164 healthy controls and subjected to polymerase chain reaction (PCR) and DNA sequencing to determine the PNPLA3 genotypes. The relative risk of the rs738409 polymorphism for CHB was estimated by calculating the odds ratio (OR) and 95% confidence interval.

RESULTSThe rs738409 G allele frequency was significantly different between the CHB and control groups (31.9% vs.21.9% respectively, P less than 0.05). Compared to he rs738409 C allele, the G allele was associated with an increased risk of developing CHB (OR =1.67, 95% CI:1.18-2.34, P =0.003). Logistic regression model analysis, with adjustment for confounding factors, indicated that carriers of the PNPLA3 rs738409 GG + GC genotype had increased risk of CHB than carriers of the CC genotype (OR =1.76 ,95% CI:1.14-2.71, P =0.011).

CONCLUSIONQingdao Han Chinese who are carriers of the rs738409 G allele are at increased risk of CHB.
