Grew on the normal temperature, it was shown that the deposits of calcium antimonate being the indicator for Ca(superscript 2+) localization mainly concentrated within the vacuoles and intercellular spaces and there was also some Ca(superscript 2+) deposits in cell walls. But when Garyota urens L. was treated by the temperature of 2℃ for 48 h, the level of Ca(superscript 2+) increased in cytoplasm and plasma membrane, but decreased in vacuoles and intercellular spaces considerably. At the same time, the ultrastructure of chloroplasts suffered from chilling: the membrane of chloroplasts had been damaged, the layer of thylakoids was exiguous and unclear, the photosynthetic rate decreased evidently. And when Garyota urens L. was treated by the temperature of 2℃ for 120 h, the deposits of Ca(superscript 2+) mainly concentrated within the cytoplasm, nucleus and plasma membrane and there was also some Ca(superscript 2+) deposits in vacuoles, and the ultrastructure of some cells was simultaneously damaged severely: Chloroplasts structure, vacuole membrane and nuclear membrane had been damaged fully, the structure within the cell had become unclear, and the cell only have respiration.

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.

Since 1962, when Gross and Lapiere discovered the first MMPs-collagenase, man had discovered various of MMPs in succession, where MMP-2 has a strong degradational effect on extracellular matrix, it is secreted bymacrophage, smooth muscle cells and endothelial cells and so on.

Theurinary IL-6 level positively correlated with density of glomerular matrix membrane, global sclerosis, fiber or fibrocellular crescents and interstitial fibrosis (p. 05). According to the degree of density of glomerular matrix membrane and interstitial fibrosis, urinary Col-IV level had better correlation than urinary TGF-betal and IL-6 levels.In IgAN, Col-IV showed increased expression in diseased renal tissue whereas the site of expression of TGF-betal was mainly localized within the cytoplasm of tubular epithelial cells. Interstial expressionwas also present but glomerular TGF-betal expression was found only in patients with heavy mesangial proliferation. There was a significant correlation between glomerular positivity for Col-IV and severity of histological damage. There was also a significant correlation between positivity for TGF-betal and Col-IV in the tubular epithelial and interstitial lesions. In contrast, there was no ralationship between glomerular positivity for TGF-betal and severity of histological damage.The urinary TGF-betal level paralleled tubular TGF-betal expression.

The five prosthetic groups (FAD, [2Fe-2S], [4Fe-4S], [3Fe-4S] and heme group) required for electron transfer from succinate to ubiquinone were unambiguously assigned into the electron density map. Besides, we find there are some electron densities around the Qp pocket at the matrix side and we believe it represents the head structure of ubiquinone, which is proved by the inhibitor bound structure that 2-TTFA just locating at the Qp site. At the same time, we find there is the second 2-TTFA binding site, locating the inter-membrane side. This finding will change our knowledge about the electron transfer inside Complex II and the ubiquinone transfer between Complex II and Complex III, and endow a new role of Complex II in electron transfer chain.
