The study showed the recombinant wt/mCREG protein depressed the VSMC proliferation depending on dose and the optimal concentration was 400nM;2biologic function of CREG protein and the membrance receptor mechanism:①effect on VSMC migration: the wound healing experiment showed the OB2 cells migration was slower significantly after added wt/mCREG(400Nm) in supernatant. The HITASY cells migration were very slowly and no remarkable change. The gelatinase digestion and Western blot analysis showed the matrix metalloproteinase was decreased and TIMPs was increased;②effect on differentiation: after added wt/mCREG(400nM), the expression of myocardin, SMα-actin, MHC and caldesmin were increased and that of LM-1 and FN were decreased in OB2 cells. These effects were more significant when adding wtCREG.;③effect on VSMC proliferation: Cell cycle assay and BrDU stain showed: after added the wtCREG and mCREG protein, the ratio of cell in G0/G1 phase increased to 0.5773 and 0.5572 from 0.5308 respectively in OB2 group, which increased to 0.7369 and 0.7034 respectively from 0.6297 in HITASY group;3Role of M6P/IGF2R in CREG biologic function:①ELISA and co-immunoprecipitation showed the wt/mCREG binding to M6P/IGF2R directly.②antibody blocking test: when the anti-IGF2R was added to medium at the same time with wt/mCREG at different concentration(2μg/mL、4μg/mL、8μg/mL),the effects of CREG protein which depressing proliferation, migration, secretion and promoting differentiation were blocked, which had the positive correlation to the concentration of added anti body. The studies showed two combinant CREG promoted VSMC switch to differentiation phaenotype, at the same time, depress VSMC proliferation, migration and secreting extracellular matrix.

The influences of environmental factors on the abiotic methylation were studied. The biggest production of methylmercury was found after 2 days of incubation in presence of FA. The rate of production of methylmercury depends upon temperature. In presence of FA from sediment, the biggest production of methylmercury was found under 40℃. In presence of FA from soil, production rate increases with temperature. The biggest production of methylmercury was found when solution pH was 2 and 4 in presence of FA from sediment and soil, respectively. Increase in concentrations of inorganic mercury and FA solution causes an increase in the production of methylmercury. Under irradiation with ultraviolet ray, blacklight lamp as well as natural light, methylation is stimulated, especial for irradiation of ultraviolet light.
