Objective To establish a macrophage-derived foam cell model of human monocytic THP-1 cell line and to identify the foam cell.Methods THP-1 cells were differentiated into macrophages after induction with 160 nmol/L phorbol-1-myristate-13-acetate for 24 hours and then incubation with 80 mg/L oxidized low density lipoprotein(oxLDL) for 48 hours.The differentiated cells were observed after oil red O staining under light microscope.High performance liquid chromatography/atmospheric pressure chemical ionization tandem mass spectrometry(HPLC-MS) was used for quantitative analysis of cellular cholesterol and cholesteryl esters contents.Results There was a large number of red lipid droplets in phorbol-1-myristate-13-acetate and oxLDL treated THP-1 cells after oil red O staining under light microscope.Cellular contents of cholesterol and cholesteryl esters in the differentiated cells increased markedly compared with the normal THP-1 monocytes by HPLC-MS assay.Conclusion A human monocyte-derived foam cell model has been established by incubating THP-1 cells with 120nmol/L phorbol-1-myristate-13-acetate for 24 and then with 80 mg/L oxidized low density lipoprotein for 48 hours.

Objective To identify the relationship among glycogenes,N-glycans and hepatocarcinoma metastasis and drug resistance by studying the differential expressions of glycogenes and N-glycans in MHCC97-H and MHCC97-L human hepatocarcinoma cell lines,and to confirm the novel target of hepatocarcinoma metastasis and anti-tumor therapy.Methods Real-time PCR was used to quantitatively analyze glycogenes and fluorescein isothiocyanate (FITC)-lectin was used to analyze glycans characteristics.RNA interference approach was used to interfere the glycogenes,and the invasive ability in vitro and drug susceptibility of MHCC97-H cells were detected before and after interference.Modification of N-glycosylation (tunicamycin and PNGase F treatment) was done,and the invasiveness in vitro,tumorigenicity in vivo and drug susceptibility of MHCC97-H cells were detected before and after modification.Results The expressions of glycogenes and glycans were different in MHCC97-H cells and MHCC97-L cells.The silence of MGAT5 in MHCC97-H cells inhibited invasion ability and increased sensitivity to 5-fluorouracil in vitro(t =7.312,P < 0.05).Modification of N-glycosylation decreased MHCC997-H cells invasion ability in vitro and tumorigenicity in vivo and increased sensitivity to 5-fluorouracil.Conclusion The differential expressions of glycogens and N-glycans in human hepatocarcinoma cell lines correlate with tumor invasion and drug resistance,and they are expected to be novel targets of tumor chemotherapy.

Objective: To establish a method for determination of mercury (Hg) and arsenic (As) contents in biological samples. Methods: Biological samples containing Hg were pretreated with digestive agents of HNO3-H2SO4 and that of As with HNO3-HClO4 and HNO3-H2O2 under the pressure of 0.5 MPa,1.0 MPa and 1.5 MPa respectively heated for 2 minutes. And then the concentrations of Hg or As were determined by intermittent flow hydride generation-atomic spectrophotofluorimetry. Results: Recoveries of Hg and As were 97.3 %~99.1 %and 99.4 %~105.7 %respectively. Conclusion: The method is simple, rapid, accurate and sensitivite and with good reproducibility and is suitable for the determination of Hg and As contents in biological samples.
