Objective To investigate the effect of rh-resistin on glucose metabolism in HepG2 cells and to elucidate whether the underlying mechanisms are related to AMPK pathway. Methods Cells transfected with control siRNA or AMPKα2 siRNA were cultured in 6-well plates and then treated with 50 ng/mL rh-resistin for 24 hours , while untransfected cells were treated with or without 50 ng/mL rh-resistin on the same conditions , followed by serum-starving in glucose-free DMEM for 3 ~ 5 hours in the continued absence or presence of rh-re-sistin. Then the cells were treated with or without insulin for 2 hours. AMPKα2, G6Pase, PEPCK and Glut2 mRNA expression levels were determined by quantitative RT-PCR. The phosphorylation state of AMPK was deter-mined by Western blotting. Glycogen synthesis was measured by the incorporation of D-[U-14C] glucose to glycogen. Results Rh-resistin suppressed the AMPKα2, Glut2 mRNA expressions, and reduced the phosphory-lation level of AMPK and glycogen synthesis on both basal and insulin-stimulated conditions (P < 0.05), while it accelerated G6Pase and PEPCK mRNA expressions on the same conditions (P < 0.05). The mRNA expression levels of G6Pase , PEPCK , Glut2 and the phosphorylation level of AMPK and glycogen synthesis were signifi-cantly different between the rh-resistin group and the rh-resistin in conjunction with AMPKα2 siRNA-treated group. Conclusion Rh-resistin may affect glucose metabolism in HepG2 cell via AMPK pathway.

Objective To investigate the effect of rh-resistin on lipid metabolism in HepG2 cells and to elucidate its relation to AMPK pathway. Methods We treated the HepG2 cells with 50 ng/ml rh-resistin and 0.5 mmol/L palmitic acid,used siRNA technique to inhibite α2 subunite expression of AMPK in HepG2 cells and quantitative RT-PCR to detect ACC1,ACC2,and HL mRNA expression levels of related lipid metabolism genes. The P-AMPK-Thr172 of AMPK and P-ACC-Ser79 of ACC were determined by Western blotting. The Lipid accumu-lation in cells was determined by images of Laser Scanning Confocal Microscope after Nile red staining. Results Rh-resistin decreased the AMPKα2,HL mRNA expressions and the phosphorylation level of AMPK and ACC in both basal and insulin-stimulated conditions (P < 0.05),had no influence on ACC2 mRNA expressions (P >0.05),while it increased ACC2 mRNA expressions and cytoplasmic lipid droplets in the same conditions (P <0.05). Conclusion Rh-resistin may affect lipid metabolism via AMPK pathway with increase of fatty acid synthe-sis and inhibition of triglyceride catabolism,which leading to lipid accumulation in HepG2 cells.

Objective:To analyse the stress distribution of the tooth and inlay with the restoration of resin,porcelain,gold alloy,co-balt chromium materials respectively.Methods:3-D finite element models of mandibular first molar with meiso-occlusal (class II) cavity and different inlays were established.Von-mises stress distribution on the tooth and inlay with vertical load and lingual load at 45°were analyzed.Results:After restoration peak stress of high elastic module materials and dental inlays was higher than that of the low elastic module material inlays,however,the restorations of the different elastic module materials had the similar stress distribution trend.The stress under of lateral load(lingual at 45°)to the teeth inlays was significantly higher than that under vertical load.Peak stress concentration of tooth was on the bottom of the cavity near the pulp chamber dentin;inlay peak stress distribution is mainly in its corresponding to the gingival wall.In the tooth tissues stress level of the contact surface of inlay restoration,the strength was as the fol-lowing:Composite resin inlay >ceramics inlay >the gold alloy ceramics inlay >cobalt chromium alloy inlay.The stress level of the inlay of the four kinds of inlay restoration materials was just opponent with the tooth tissues.Conclusion:Gingival wall is the weakest part of meiso-occlusal(class II)cavity inlay restoration,while near the pulp chamber at the bottom of the cavity is the weakest part of the tooth.Among the 4 materials Under the same load condition,composite resin inlay restoration has minimal tooth stress and uniform stress distribution,and can reduce the posibility of odontoschism and microleakage.
