title: [Model building-up and observation on the mouse carried chronic hepatitis B and nonalcoholic fatty liver disease].
abstract: OBJECTIVE
  Establish the model of mouse with chronic hepatitis B virus (HBV) and nonalcoholic fatty liver disease (NAFLD).
  
  
  METHODS
  Take 100 HBV transgenic, BALB/c mice of 4 weeks old, with each gender half. Then pick out 70 mice in one group to feed high-fat feed and the rest to feed normal feed. At the end of week 16, random kill 10 mice of high-fat, then liver tissue and serological detection target identification model is established in this paper. After that, divide the mice into model group and comparison group with 30 mice in each group. Feed model group with high-fat feed, comparison group with normal feed and normal group with normal feed till week 72 (including previous 16 weeks). Kill 10 mice of each group at the end of week 24, 48 and 72 respectively, fully automatic biochemical instrument detection of serum ALT, AST, TC, TG, FBG, fluorescence quantitative PCR method to detect HBV-DNA, chemiluminescence detection of HBsAg, liver biopsy after HE staining to evaluate histology change, observe mice model of dynamic evolution.
  
  
  RESULTS
  (1) Feed high fat feed after 16 weeks, mice's weight, serum ALT, AST, TC, TG, FBG and blood biochemical indicators increased, HBV-DNA positive, liver HE staining obviously big blister fatty degeneration of liver cells and within the lobule lymphocytes infiltration, NAFLD activity score (NAS) getting close to NASH, the model of chronic HBV carries with NAFLD mouse built successfully. (2) The TC and TG values of model group in each period were higher than that of comparison group and normal group. (3) In week 24 and 72, HBV-DNA values of each group are obvious different from the other two groups and the difference can be applied to statistical significance (P < 0.05). (4) In week 48 and 72, NAS of each group are obvious different from the other two groups and the difference can be applied to statistical significance (P < 0.05).
  
  
  CONCLUSIONS
  (1) Chronic HBV carries with NAFLD mice model can be established by HBV transgenic mice fed by high fat feed. (2) NAFLD accelerates the liver disease of the mice carrying HBV to some extent.
