OBJECTIVE: To establish a model of alcoholic liver fibrosis (ALF) in rats induced by complex factors. METHODS: Forty-seven healthy male rats were divided into three groups: normal control group (n=12), minor CCl4 group (n=12) and complex factors group (n=27). The rats in the complex factors group were fed a complex diet including alcohol, corn oil and pyrazole, and administered with intraperitoneal injection of minor CCl4 to induce ALF. During induction process, the histopathological changes of liver tissue and the values of liver-to-body weight ratio were both observed regularly. The serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyltransferase (gamma-GT) in these three groups were all examined at the 12th week of the induction process. RESULTS: At the 12th week of the induction process, the model of ALF induced by complex factors was successfully established in rats, and the histopathological presentations showed alcoholic fatty liver, hepatitis and liver fibrosis in a sequence along with the induction process. The value of liver-to-body weight ratio and the serum levels of ALT, AST and gamma-GT of rats in the complex factors group were all significantly different from those in the other two groups. CONCLUSION: It is a steady and effective way to induce ALF in rats with complex diet and minor CCI4 injection.

OBJECTIVE:
To evaluate the sub-acute oral effect of titanium dioxide (TiO2) nanoparticles on the oxidation/antioxidation biomarkers and inflammatory cytokines in blood, liver, intestine, and colon in rats.
METHODS:
Twenty four 4-week-old clean-grade Sprague Dawley (SD) rats were randomly devided into 4 groups by body weight (n=6, control, low, middle, and high), in which the rats were orally exposed to TiO2 nanoparticles at doses of 0, 2, 10 and 50 mg/kg body weight/day for 28 consecutive days separately. Food intake, body weight and abnormal behaviors during the experiment were recorded. The rats were euthanized on the 29th day. The blood was collected via abdominal aortic method and centrifuged to collect the serum. Tissues from liver, intestine and colon were collected and homogenated. Then enzyme-linked immunosorbent assay (ELISA) and microwell plate methods were used to detect oxidation/antioxidation biomarkers including superoxide dismutase (SOD), glutathione (GSH), glutathione peroxidase (GSH-Px), total mercapto (T-SH), glutathione disulfide (GSSG), malomdialdehvde (MDA) and inflammatory cytokines including interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) in the serum, liver, intestine and colon in the rats.
RESULTS:
Compared with the control group, no significant differences in body weight, food intake and organ coefficients were observed in all the three groups after TiO2 gavage. No significant changes in GSH, GSH-Px, T-SH, and IL-6 were observed. Compared with the control group, significant increase of SOD activity in serum in high dose group, signi-ficant increase of GSSG concentration in intestine in middle and high dose group and significant increase of MDA concentration in liver in low and high dose group were observed. Compared with the control group, a significant increase of TNF-α in liver in middle and high dose group was observed.
CONCLUSION
TiO2 nanoparticle can increase antioxidant enzymes activities in blood, increase oxidative biomarkers in liver and intestine, increase inflammatory cytokines in liver in rats after a 28-day sub-acute orally administration. Among blood, liver, intestine, and colon, liver is most sensitive to the toxicity induced by TiO2 nanoparticles, followed by intestine, blood, and colon in sequence.

Objective To evaluate the feasibility and effect of three-points ablation approach in in treatment of typical atrial flutter guided by CARTO. Methods Twenty-six patients with typical atrial flutter diagnosed by ECG and electrophysiological study (EPS) were enrolled in this study. Activation sequence mapping and linear ablation were performed in 11 patients (conventional group) . Three-points guided linear ablation with CARTO system was performed in another15 patients (three-points group) . Results There was no significant difference in the success rate between the two groups. Both the procedure and fluoroscopic time in three-points group were significantly shorter than that in conventional group [(72.66±29.82) vs (102.52±32.61) min;(4.26±2.76) vs (7.32±3.16) min] . Conclusions The three-points ablations approach is as safe and effective as conventional ablation approach in treatment of typical atrial flutter;however,the former can significantly shorten the procedure time and fluoroscopy time.
