Aim: To explore the effect of calcium ionophore (CI) on dendritic cells (DC) derived from peripheral blood monocytes.
Methods: Peripheral blood monocytes from healthy donors were treated with 100 microg/L rhGM-CSF, 100 microg/L rhGM-CSF plus (10 microg/L) CI, and 100 microg/L rhGM-CSF plus (100 microg/L) respectively. After cultivation of 40 hours, cellular morphology was observed under light microscope and electron microscope. Surface markers on treated PBMCs were analyzed by flow cytometry. MTT colorimetry was used to detect proliferation of autologous T cells.
Results: Peripheral blood monocytes treated with 100 microg/L rhGM-CSF plus 100 microg/L CI for 40 hours showed typical morphology of DCs. Simultaneously there was a decrease in CD14 expression and increase in HLA-DR, CD40, CD83 and CD86 expressions on these cells. In addition, PBMCs treated with 100 microg/L rhGM-CSF pass 100 microg/L CI for 40 hrs. Could evidently stimulate proliferation of autologous T cells.
Conclusion: CI can markedly enhance transformation of peripheral blood monocytes induced by GM-CSF into DCs.

Objective: To study the effect of total saponins from Rhizoma Dioscoreae nipponicae (RDN) on the expression of stroma cell derived factor 1 (SDF1) and IKB kinase (IKK) in rIL-1beta induced fibroblast-like synoviocytes (FLS).
Methods: FLS were primarily cultured and the 3rd generation log phase growth FLS were divided into the normal control group, the model group, and the medication group. 10 microg/L rIL-1beta was used to induce the proliferation of FLS in the model group.
A gas chromatography-mass spectrometry (GC-MS) method for the determination of hexachlorocyclohexane (BHC) and dichlorodiphenyltrichloroethane (DDT) residues in honey was developed using dispersive liquid-liquid microextraction (DLLME) as sample preparation method. The samples were extracted with chloroform, and concentrated into chloroform by vortex and centrifuging. The analytes were analyzed by GC-MS.

The relationship is shown between a concentration of urinary iodine and serum thyroglobulin in population studies carried out on a general population that was randomly selected from the registry of the General Health Insurance Company (individuals aged 6-98 years, 1751 males, 2420 females). The individuals were divided into subgroups with a urinary iodine concentration of <50, 50-99, 100-199, 200-299 and >/=300 microg/l. The mean and median of thyroglobulin were calculated in these subgroups.
