Aim To establish hyperlipidemic model and study the molecular mechanism of triglyceride (TG)disorder in hamsters.Methods The male ham-sters were randomly divided to control group fed with standard diet and model group fed with high-fat diet, both of the groups had been fed with diet for 4 weeks. The levels of serum TG,TC,LDL-C,FFA were detec-ted at the end of 2nd and 4th week.The hepatic TG, TC,LPL activity were detected by enzymatic method at the end of 4th week.The molecular mechanism was tested by real-time PCR.Meanwhile the effect of posi-tive drug fenofibrate on the model of hyperlipidemia in hamsters was investigated.Results Compared with the control,the serum levels of TG,TC,LDL-C,FFA in the model group increased 2.57,1.93,2.49,1.25 times at the end of2nd week,and 3.93,1.90,2.27, 2.29 times at the end of 4th week,respectively.The positive drug significantly decreased the concentrations of serum TG and FFA. The mechanism research showed that the hepatic AMPK,PPARα,CPT-1 mRNA decreased in hamsters fed with high-fat diet,and the SREBP-1 c,ACC,SCD-1 ,AGPAT2,DGAT2 mRNA ex-pressions increased.The hepatic ApoB mRNA expres-sion was up-regulated while the MTTP and LPL mRNA expressions were down-regulated slightly.LPL activity significantly decreased in model hamsters compared with the control.The alternations of these enzymes and receptors were the critical factors for TG disorder. Conclusion The hamsters fed with high-fat diet for 4 weeks can form a good hyperlipemic model with HTG feature.AMPK,SREBP-1 c,ACC,SCD-1 ,DGAT2,AG-PAT2,PPARα,CPT-1 and LPL are not only the main mechanisms of TG disorder,but also the biomarkers of hypotriglyceridemic drugs.

Aim To establish the hyperlipidemic model and ex-plore the mechanism of hypercholesterolemia in hamster. Meth-ods Hamsters were randomly divided into the control and model groups. The hamsters in the control group were fed with the standard chow and the model group were fed with the high fat di-et. Serum lipids and CYP7A1 activity were detected by enzymat-ic method. The molecular mechanism of cholesterol metabolism was investigated by real-time PCR. Results In comparison with the control group, the concentrations of serum TC, LDL-C, TG and hepatic TC, TG were significantly increased in the model
group. The mechanism research showed that in hamsters fed with the high fat diet, the CYP7A1 activity and the mRNA expres-sions of hepatic LDL-R, SREBP-2, CYP7A1, LXRαwere down-regulated, the expression of hepatic FXR was up-regulated. Conclusion The hyperlipidemic model could be developed in hamsters fed with the high fat diet for 4 weeks. LDL-R, SREBP-2, CYP7A1, FXR and LXRαare the biomarkers of hypercholes-terolemia, and also the targets of hypolipidemic drugs.

Object To study the effects of active fraction L.F04 from the ground part of Lycopus lucidus Turcz. var. hirtus Reg. on platelet aggregation and thrombosis formation and investigate its mechanisms of promoting blood circulation and removing blood stasis. Methods The effects of L.F04 on platelet aggregation induced by ADP in vivo, thrombosis of artery vein side road and thrombus formed in rotary loop in vitro were examined, the rat model of blood stasis made by injecting high molecular weight dextran (HMWD) was used. Results L.F04 0.408 and 0.204 g/kg evidently inhibited the ADP induced increase of platelet maximum aggregation rate in vivo in HMWD model, with a concentration dependent manner. Compared with the control group, the thrombus weight in rat model of blood stasis was increased significantly and the length of thrombus was shown an increasing trendency. L.F04 0.408 and 0.204 g/kg both shown the anti thrombosis effect. L.F04 0.408 g/kg showed better effects of lessening the thrombus dry weight and wet weight. Both L.F04 0.408 and 0.204 g/kg could inhibit the thrombosis of artery vein side road, the inhibition rates are separately 27.41% and 27.14%. Conclusion L. lucidus var. hirtus F04 could significantly inhibit platelet aggregation and thrombosis formation.

Objective To investigate the boosting efficiency of a subunit vaccine consisting of the fusion protein Ag85B-Mpt64190-198-Mth8.4 (AMM) , dimethyl-dioctyldecyl ammonium bromide (DDA) and BCG polysaceharide nucleic acid (BCG-PSN) on the primed inoculation with BCG. Methods The AMM subunit vaccine was composed of fusion protein AMM, adjuvant DDA and BCG-PSN. The first mouse experi-mental group was immunized with BCG first, then boosted with the AMM subanit vaccine in the 10th week. The second experimental group was boosted with the AMM subunit vaccine in the 8th week and the 10th week respectively with a two weeks interval after the primed with BCG. Two control groups were treated re-spectively with physiological saline alone and BCG alone. After the primed inoculation, ELISPOT and ELISA were used for the detection of the cell-mediated and humoral immune response in week 14 and week 22 re-spectively. Furthermore, the immunized mice were challenged with live BCG to mimic tuberculosis infection in the 22nd week after the primed inoculation. Subsequently the T cell typing and humoral response were de-tected by flow cytometry and ELISA, respectively. Results ( 1 ) The level of secreting IFN-γ: 14 weeks af-ter the primed inoculation,with the stimulation of the specific antigen-Ag85B, the number of cells secreting IFN-γ in the second experimental group (135±14) was more than BCG alone immunized group (19±16), t = 10. 98, P < 0.01. In the 22nd week, the number of cells secreting IFN-γ in the second experimental group (208±11) was still more than BCG alone group (57±18), t =6.43, P <0.01. (2) The level of humoral immune response: the IgG1 antibody titer in the second experimental group was obviously higher than that in the first experimental group. However, the ratio of IgG2a to IgG1, as the index reflecting the Thl-type immune response, in the experimental group 2 was lower than that in the experimental group 1. (3) The contents of CD4+ CD25+ T cells after challenged with live BCG strain: the first and the second ex-perimental groups were both higher than the BCG alone group (t1 = 3.08, t2 = 3.16, P < 0.05 ). Conclu-sion Boosting the BCG-pfimed mice with tuberculosis AMM subunit vaccine twice can induce higher level of cell-mediated and humoral immune response than BCG alone, which could activate the regulative immune response at the same time.

Objective To construct protective immunity to Mycobncterium tuberculosis latent infection, a novel fusion protein consisting of HspX, the 190 to 198 peptide of Mpt64 and Ag85B, which were confirmed to be the effective protective antigens mainly expressed in the dormancy and exponential phase of growth, was constructed and its immunogenicity was investigated. Methods Ag85B and Mpt64190-198-HspX sequences were amplified by PCR and cloned into plasmids pET-28a. The fusion protein, Ag85BMpt64190-198-HspX (AMH) was expressed in E. coli BL21 and purified with Ni-NTA resins. C57BL/6 mice were immunized three times at 2-week intervals subcutaneously with AMH formulated with the adjuvant composed of dimethyl-dioctyldecyl ammonium bromide (DDA) and BCG polysaccharide nucleic acid (BCGPSN). Humoral and cell-mediated immunity responses were analyzed at five weeks after the last injection. Results AMH was expressed stably in E. coli and could be purified well by Ni-NTA affinity chromatography. C57BL/6 mice immunized with AMH subunit vaccine generated specific cellular and humoral immunologic response to the stimulation of Ag85B, Mpt64190-198 and HspX. Conclusion It suggested that AMH was a promising candidate antigen of tuberculosis subunit vaccine.
