Objective To investigate the different expressions of adiponectin receptor 2(AdipoR2) mRNA in liver between diet-induced obese rats and controls.Methods The level of AdipoR2 mRNA expression was detected by reverse transcriptase polymerase chain reaction(RT-PCR).Insulin sensitivity was evaluated by insulin sensitivity index(ISI).Results Diet-induced obese rats showed higher expression of AdipoR2 mRNA compare to controls.The ISI of diet-induced obese rats was lower than that of controls.Conclusion High energy diet induceds AdipoR2 expression in liver.

By Silica gel, Sephadex LH-20 and other materials for isolation and purification and by physicochemical methods and spectral analysis for structural identification, 32 compounds were isolated and identified from ethyl acetate portion of alcohol extract of the Osmanthus fragrans. Their structures were identified as boschniakinic acid (1), ursolaldehyde (2), augustic acid (3), arjunolic acid (4), 5-hydroxymethyl-2-furancarboxaldehyde (5), isoscutellarein (6), 6, 7-dihydroxycoumarin (7), 2α-hydroxy-oleanolic acid (8), quercetin-3-0-β-D-glu-copyranoside (9), D-allito (10), 5, 4'-dihydroxy-7- methoxyflavone-3-0-β-D-glucopyranoside (11), 5,7-dihydroxychromone (12), lupeol (13), naringenin (14), acetyloleanolic acid (15), chlorogenic acid (16), kaempferol-3-0-β- D-glucopyranoside (17), oleanolic acid (18), kaempferol-3-0-β-D-galactopyanoside (19), 3', 7-dihydroxy-4'-methoxyisoflavon (20), ergosta-4,6,8 (14), 22-tetraen-3-one (21), p-hydroxycinnamic acid (22), syringaresinol (23), 3,4-dihydroxyacetophenonel (24), β-sitosterol (25), ethyl p-hydroxyphenylacetate (26), benzoic acid (27), caffeic acid (28), coelonin (29), p-hydorxy-phenylacetic acid (30), p-hydroxyacetophenone (31), and methyl-p-hydroxphenylacetate (32). Except for compounds 2, 4, 5, 8-11, 13, 15, 18, 20, 25, and 27, the rest were isolated from the Osmanthus fragrans for the first time.

BACKGROUNDTo study the composition and significance of the inclusion bodies of human cytomegalovirus (HCMV).

METHODSMicrodissection of inclusion bodies, PCR and Southern blot were adopted to detect DNA, and immunohistochemistry method and catalyzed signal amplification (CSA) were used to detect the different antigens of HCMV.

RESULTSThe inclusion bodies of HCMV were separated from the tissue section of human salivary gland. The fragments amplified by PCR from these dissected inclusion bodies were confirmed to be the DNA of HCMV. With the immunohistochemical method CSA, the immediately early and early antigens of HCMV were detected with monoclonal antibodies DDG9/CCH2, while matrix protein AAC10 was negative in the inclusion bodies.

CONCLUSIONThe ingredient of inclusion bodies of HCMV included the DNA and the antigens expressed in specific stage of the virus.

Myeloid differentiation factor MyD88 is a critical adaptor molecule that integrates and transduces intracellular signals in inducing the differentiation of dendritic cells (DCs).The domain regions within MyD88 was searched,it could potentially affect the function of dendritic cells and found that MyD88 aa155-171 motif not only regulate the activity of transcription factor NF-?B, but also control the production of cytokines and expression of costimulatory molecules. Indeed, aa155-171 motif deleted type MyD88 (MyD88155-171) transfected RAW264.7 cells exhibited the reduced NF-?B and AP-1 activity and interrupted the expression of CD86 and B7H1. Meanwhile, lower level expression of cytokines such as IL-12,IFN-? were also observed by means of cytokine array in MyD88-/-DC trasfected with MyD88155-171 as compared to the MyD88 transfected cells. Thus, aa155-171 motif inside MyD88 could affect the expression of costimulatory molecules, production of cytokines and transduction of Toll like receptor signal pathway, suggesting that this motif may play an important role in regulating responses of innate immune system.

Objective To explore a better method for treatment atrophic rhinitis.Methods 56 patients with atrophic rhinitis(96 lateral)were treated by nasal submucou pediculated bone-suberiosteal muscle flap extracted from anterior wall of sinus maxillaries.Results All patients were followed 2 to 10 years,total effective rate was 100 %, with 49 cases(87.5 %)showing prominent effect.Conclusion The grafted flap cannot be assimilated,felled off and necrosis,because the flap has rich blood supply.This methods has obvious short-term effective and stable long-term effective.No complications were found.

OBJECTIVETo study of exogenous substances on the germination rate of Platycodon grandiflorum and offer the basis for the standardized culture of P. grandiflorum.

METHODAt 25 degrees C, under darkness and lightness, do pretreatmeats on seeds by using GA3, H2O2, KMnO4, PEG at different concentrations.

RESULTThe results indicated that the pretreatments with GA3 at a concentrating of 50-250 mg x L(-1) and 1%-2% of H2O2 could increase germination of P. grandiflorum seed at a certain degree. Contrariwise 0.1%-0.5% of KMnO4 and 15%-35% of PEG inhibited the germination.

CONCLUSIONPretreatment with 50-250 mg x L(-1)GA3 and H2O2 at a low cencontration could increase the seed germination of P. grandiflorum.
