Objective To detect serum concentrations of Dickkopf-1(DKK-1) and soluble receptor activator of nuclear factor-κB ligand (sRANKL) in patients with multiple myeloma (MM) and to investigate its clinical significance. Methods Serum DKK-1, sRANKL, osteoporotegerin(OPG) and tartrate-resistant acid phosphatase 5b (TRACP-5b) levels were quantified in 30 newly diagnosed MM patients and 20 healthy control subjects by using sandwich ELISA. Results The serum DKK-1, sRANKL,OPG and TRACP-5b levels were significantly higher than those in the healthy controls (42.96 μg/L vs 5.33 μg/L, 1.83 pmol/Lvs 0. 79 pmol/L, 1799. 30 pmol/L vs 822.40 pmol/L, 5.81 U/L vs 0. 28 U/L, respectively; all P＜0. 05). Serum levels of DKK-1 were positively correlated with sRANKL and TRACP-5b, respectively.Serum concentrations of DKK-1 and sRANKL were significantly elevated in stage Ⅲvs stages Ⅰ and Ⅱaccording to International Staging System (ISS) (46. 33 μg/L vs 37.91 μg/L, 2.26 pmol/L vs 1.19pmol/L, respectively, all P ＜0.05). Serum concentrations of DKK-1 , sRANKL and TRACP-5b were significantly higher in patients with more than 3 lytic bone lesions than those with only 1-3 lytic bone lesions (46. 30 μg/L vs 31.98 μg/L, 2. 18 pmol/L vs 0. 69 pmol/L, 6.02 U/L vs 5. 13 U/L, all P ＜ 0.05).Conclusions MM patients have increased serum DKK-1, sRANKL, OPG and TRACP-5b levels as compared with the healthy controls. Serum concentrations of DKK-1 and sRANKL have close relationship with MM stage and lytic bone disease.

Objective To study the effect of TanshinoneⅡA(TSN) on vascular smooth muscle cells(VSMCs) induced by high glucose and its relationship with MAPK signal pathway.Methods After the establishment of the model of diabetic rats,the aortic of rats was isolated and cultured.DNA synthesis was analyzed by ELISA of BrdU.The activity of MAPK was measured by liquid scintillation counting.Results TSN inhibited the proliferation and DNA synthesis of vascular smooth muscle cells from diabetic rats in dose-dependent manner.TSN at the dosage of 0.5 mg/L significantly decreased the activity of MAPK as well as of U0126.Conclusion The effect of TSN on the proliferation and DNA synthesis of vascular smooth muscle cells from diabetic rats is potentially mediated by inhibition of MAPK.

Objective:To compare the content differences of 18 amino acids in plancenta histolysate determined by pre-column de-rivatization HPLC and post-column derivatization cation-exchange chromatography ( AARO) . Methods: The HPLC method was per-formed on a C18 column and 2, 4-dinitro chlorobenzene ( DNCB) was used for pre-column derivatization, and then the determination was carried out after adding 0. 1 mol·L-1 borax buffer (pH=9. 1), and the AARO method was used for the direct determination with a strong acid cation-exchange chromatographic column and post-column derivatization. Results: The RSD for reproducibility of the AARO method was 1. 84%-0. 91%, while that of the HPLC method was 1. 87%-1. 04%. Conclusion:Both AARO method and HPLC method can be used for the quantitative determination of 18 amino acids in plancenta histolysate with the similar results. However, pre-column derivatization HPLC method may cause incomplete derivatization and instable derivatives.
