The granulation of blast furnace slag （BFS） with water quenching treatment has some disadvantages, such as high water consumption and difficulty for recovery heat. So developing a new dry granulation technique to treat BFS is very important. The applicability of BFS directly depends on the content of non-crystalline solids in the slag after treatment. So it is of theoretical and practical significance to analyze the content of non-crystalline solids in the slag quantitatively and simply. Metallographical test is mainly adopted to quantify the non-crystalline in BFS so far with the shortages such as complex sample, difficult determination, ect. The diffraction intensity of non-crystalline is proportionate to the content of non-crystalline in BFS, ~ray diffraction method was adopted to quantify the noncrystalline and the crystalline solids in BFS. The quantitative coefficient between the crystalline and the non-crystalline solids of BFS is 0.70 of BFS whose main composition （mass percent, %） is： CaO 38.2, SiO2 35.7, Al2Oa 16.3, and MgO 8.3. The relative error of X-ray diffractometer for quantitatively analyzing non-crystalline content of BFS is less than 1%.

Based on the antiplatelet aggregation mechanism and the bioisosterism principle of the reference drug picotamide, thirteen novel derivatives of arylamide and arylsulfonamide were designed and prepared. The biological activities of these derivatives were investigated. The chemical structures of the target compounds were confirmed by ^1H NMR and IR. The in vitro activities of antiplatelet aggregation of the thirteen target compounds were assessed by Bore＇s method. Compounds 2b and 8h have significant antiplatelet aggregation activities, which are superior to the corresponding activity of Picotamide.

Emerging evidence has indicated that BRCC36-mediated K63-linked ubiquitination modification was involved in diverse cellular functions,including endocytosis,apoptosis and DNA damage repair. We previously showed that activation of c GMP / PKG pathway contributed to the binding of BRCC36 and the pro-fibrotic factor Smad3. The current study tested the hypothesis that BRCC36 functions as a negative regulator of transforming growth factor-beta( TGF-β) / Smad3 pathway and participates in cardiac remodeling. In isolated adult mouse cardiac fibroblasts,we have demonstrated that TGF-β1 treatment significantly increased the expression of BRCC36. Overexpression BRCC36 suppressed TGF-β1-induced Smad3 phosphorylation,nuclear translocation,extracellular matrix molecular expression and cell proliferation. On the contrary,silencing BRCC36 by transfection of adenovirus-carrying BRCC36 sh RNA potentiated to enhance the pro-fibrotic effect of TGF-β. In vivo,under chronic pressure overload condition-induced by transverse aortic constriction,myocardial pro-survival protein Bcl-2 and Mcl-1 expression were significantly decreased and the pro-apoptosis protein Puma was increased. However,the cardiac-specific over-expression of BRCC36 significantly increased myocardial Bcl-2 and Mcl-1 and inhibited Puma expression. Interestingly,we also found that sustained pressure overload resulted in a significant myocardial DNA injury in wild type mice,which was characterized by the increase of γH2AX level. However,cardiac-specific BRCC36 over-expression significantly decreased the level of γH2AX in the pressure overloaded heart in the transgenic mice,while effectively enhanced myocardial RAD51 expression,a marker of DNA damage repair. Furthermore,BRCC36 over-expression effectively attenuated TAC-induced cardiac fibrosis and remodeling in the transgenic mice,compared with the wild type mice. Collectively,the results have suggested that BRCC36 effectively protected heart against chronic pressure overload
