This study aimed to investigate the involved immunologic mechanism of pure total flavonoids from Citrus (PTFC) on the development of non-alcoholic steatohepatitis (NASH). C57BL/6 mice were fed with high .fat diet for 16 weeks to induce the NASH model, and from the 7th week three dosages (25, 50 and 100 mg x kg(-1) x d(-1)) of PTFC were administrated intragastric for 10 weeks respectively. Serum TG, CHOL, ALT, AST were determined by biochemical assay, histopathological changes of the liver tissue were observed by HE staining, expression of RORyt and Foxp3 mRNA of the liver tissue was detected by Real-time PCR, and serum IL-17, IL-6, IL-10 and IL-4 were determined by.Cytometric Beads Array. As a result, we find that after the administration of PTFC, the in- flammation of the liver tissue of NASH mice was attenuated, liver function was improved, and the expression of RORgammat mRNA was higher in the liver tissue while which was lower of Foxp3 mRNA, the level of proinflammatory cytokines IL-17 and IL-6 decreased and the level of suppressive cytokines IL-10 and IL-4 increased. These data show that PTFC protects the development of NASH through regulating the Th17/Treg balance and attenuating inflammation.

OBJECTIVETo observe the effect of pure total flavonoids from Citrus (PTFC) on the hepatic fatty degeneration, inflammation, oxidative stress and SIRT1/PGC-1alpha expressions in mice with non-alcohol steatohepatitis (NASH), and discuss the action mechanism of PTFC on NASH.

METHODMice were given high-fat diet for 16 weeks to induce the NASH model. Since the seventh week after the model establishment, the mice were intervened with 100, 50 and 25 mg x kg(-1) x d(-1) PTFC for 10 weeks. The pathologic changes in hepatic tissues were observed with HE staining. The contents of TG, CHOL in hepatic tissue, as well as the levels of AST, ALT in serum were detected by using the biochemical process. The expression of SIRT1, PGC-1alpha and MnSOD mRNA in hepatic tissues were detected with Real-time PCR assay. SIRT1, PGC-1alpha protein and 8-OHdG expressions were determined with the immunohistochemical method. The SOD level in hepatic tissues was tested by the xanthine oxidase method. The MDA content in hepatic tissues was examined by the thiobarbituric acid method.

RESULTThe contents of TG, CHOL, NAFLD activity scores and ALT level in serum in hepatic tissues of mice in the model induced by fat-rich diet were obviously higher than that of the normal group (P < 0.010. The SIRT1, PGC-1alpha, MnSOD mRNA and protein expression in hepatic tissues were significantly lower than that of the normal group (P < 0.01). The expression of 8-OHdG and the content of MDA in hepatic tissues were obviously higher than that of the normal group (P < 0.01). After the intervention with different doses of PTFC, the NAFLD activity scores, the content of TG and the level of AST in serum were notably lower than that of the normal group (P < 0.01, P < 0.05); whereas the SIRT1, PGC-1alpha, MnSOD mRNA and protein expression were obviously higher than that of the normal group (P < 0.01, P < 0.05), with the significant decrease in the expression of 8-OHdG and the content of MDA (P < 0.01).

CONCLUSIONOxidative stress/lipid peroxidation enhancement in in NASH mice induced by high-fat diet may be related to the changes in SIRT1/PGC-1alpha signal transduction pathway. PTFC could enhance the anti-oxidant capacity in liver, relieve the damage of reactive oxygen during the fatty acid metabolic process, and prevent NASH from the occurrence and development by regulating the SIRT1/PGC-1alpha signal pathway.

Objective To assesse the quality of life of patients after cardiac pacemaker implantation using the Chinese version of SF-36.Methods Ninety-eight patients with permanent cardiac pacemaker implantation were investigated before and after the operation in terms of quality of life by using the Chinese version SF-36.Results Successful surgery was performed on all the 98 patients.The previous symptoms of the patients were improved to vari- ous extend after the operation.The quality of life of the patients was significantly improved after operation as demon- strated by the significant difference of the scores in 9 domains of SF-36 when compared with those before the operation (P

The skin ulceration syndrome of sea cucumber is a kind of desease induced by bacterium.In order to investigate the bacterium of infected sea cucumber and detect the N-acyl-homoserine lactones(AHLs) se-cretion of the bacterium,7 bacterial strains were isolated from the infected sea cucumber.These strains were identified by physiological-biochemical characteristics and 16S rDNA sequence.Results show that strain C6 belongs to Tenacibaculum,strain 4 belongs to Shewanella putrefaciens group,strain TB belongs to Vibrio,strain BP2,BP3,BP4 and BP6 belong to Pseudoalteromonas,respectively.AHLs were detected with strain Agrobacterium tumefaciens KYC55.Among these bacterial strains,strain C6,4,TB,BP3 and BP4 can se-cret AHLs,while strain BP2 and BP6 can’t.And the AHLs activity differs,from the highest to the lowest are 4,TB,BP4,BP3 and C6.
