1.Diabetes mellitus and primary liver cancer: risk factor or real cause?
Journal of Clinical Hepatology 2017;33(4):757-762
With an increasing prevalence all over the world,diabetes mellitus is considered as a potential cause of liver cancer in patients with non-viral hepatitis.Whether diabetes mellitus is the cause of liver cancer and related pathogenesis remain unknown.The article reviews recent large-sample cohort studies and confirms that diabetes mellitus increases the incidence rate of liver cancer and affects its prognosis.This article also investigates the association of hepatitis C,obesity,and nonalcoholic fatty liver disease with diabetes mellitus and liver cancer and finds that insulin resistance and activation of chronic inflammatory factors may be involved in the generation and proliferation of cancer cells.This article elaborates on the influence of anti-insulin resistance drugs on the development and progression of liver cancer and points out that diabetes mellitus may be the cause of liver cancer.Effective control of insulin resistance can help to reduce the development and progression of diabetes-associated liver cancer.

To determine the lysis spectrum of Yersinia enterocolitica bacteriophage phiYe-F10 and to analyze the relationship between the lysis ability of phiYe-F10 and the virulence gene of Yersinia enterocolitica. To observe the lysis ability of the phage phiYe-F10 to the different Yersinia strains with the double-layer technique. The strains used in this study including 213 of Yersinia enterocolitica and 36 of Yersinia pseudotuberculosis and 1 of Yersinia pestis. The virulence genes of these Yersinia enterocolitica (attachment invasion locus (ail) and enterotoxin (ystA, ystB) and yersinia adhesin A (yadA), virulence factor (virF), specific gene for lipopolysaccharide O-side chain of serotype O : 3 (rfbc) were all detected. Among the 213 Yersinia enterocolitica, 84 strains were O : 3 serotype (78 strains with rfbc gene), 10 were serotype O : 5, 13 were serotype O : 8, 34 were serotype O : 9 and 72 were other serotypes. Of these, 77 were typical pathogenic Yersinia enterocolitica harboring with virulence plasmid (ail+, ystA+, ystB-, yadA+, virF+), and 15 were pathogenic bacterial strains deficiency virulence plasmid (ail+, ystA+, ystB-, yadA-, virF-) and the rest 121 were non pathogenic genotype strains. PhiYe-F10 lysed the 71 serotype O : 3 Yersinia enterocolitica strains which were all carried with rfbc+, including 52 pathogenic Yersinia enterocolitica, 19 nonpathogenic Y. enterocolitica. The phiYe-F10 can not lysed serotype O : 5, O : 9 and other serotype Y. enterocolitica, the lysis rate of serotype O : 3 was as high as 84.5%. The phiYe-F10 can not lysed Yersinia pseudotuberculosis and Yersinia pestis. Yersinia phage phiYe-F10 is highly specific for serotype O : 3 Yersinia enterocolitic at 25 degrees C, which showed a typical narrow lysis spectrum. Phage phiYe-F10 can lysed much more pathogenic Y. enterocolitica than nonpathogenic Y. enterocolitica.

Objective To investigate the effect of propofol on the gap junction function of BRL-3A cells and cisplatin-induced toxicity to rat hepatic BRL-3A cells. Methods Rat hepatic BRL-3A cell line was provided by professor Tao laboratory of department of pharmacology of our university and cultured in DMEM liquid culture medium at 37℃. The cells were randomly divided into 6 groups: group Ⅰ control (group C) ; group Ⅱ was exposed to intralipid (the solvent) 10 μg/ml (group Ⅰ) ; group Ⅲ was exposed to oleamide (gap junction function inhibitor) 25 μmol/L (group O) and group Ⅳ ,Ⅴ , Ⅵ were exposed to propofol l.5, 2.8 and 4.1 μg/ml respectively (groups P1, 2,3) . Using parachute dye-coupling assay, the dye spread rate and inhibition rate were calculated to measure the gap junction function of BRL-3 A cells. BRL-3 A cells were seeded in two different densities:high density group (seeding density = 1×105 /ml) and low density group (seeding density = 500/ml). Both groups were further divided into 5 subgroups: subgroup Ⅰ control; subgroup Ⅱ was exposed to cisplatin 2.5 μmol/L and subgroup Ⅲ ,Ⅳ ,Ⅴ were exposed to cisplatin 2.5 μmol/L + intralipid 10 μg/ml or oleamide 25 μmol/L or propofol 2.8 μg/ml respectively. The effect of propofol on the cytotoxicity of cisplatin was evaluated by standard colony-forming assay. Results The dye spread rate was significantly lower and inhibition rate higher in groups O,P1 , P2 and P3 than in group C. Propofol decreased the dye spread rate and increased inhibition rate in a concentration-dependent manner. Propofol and oleamide significantly increased colony formation rate in high density group,but had no significant effect on colony formation rate in low density group. Conclusion Propofol can inhibit the gap junction function of BRL-3A cells in a concentration-dependent manner and reduce cisplatin-induced cytotoxicity by inhibiting gap junction function.
