A new mononuclear copper (II) complex, [Cu(dbpy)2Cl]OH0.5CH3OH2H2O (dbpy = 4,4?dimethyl-2,2?bipyridine) (C24.50H31ClCuN4O3.50, Mr = 536.52) has been synthesized and its crystal structure was determined by X-ray diffraction method. It crystallizes in monoclinic, space group P2/c with a = 13.383(6), b = 7.653(3), c = 14.164(6) ? b = 105.395(8), V = 1398.7(10) 3, Z = 2, Dc = 1.274 g/cm3, m = 0.908 mm-1, F(000) = 560 and R = 0.0773 for 1467 observed reflections with I>2s(I). Each copper(II) ion is coordinated by two dbpy and one Cl- ion and the coordination geometry can be described as a distorted trigonal bipyramidal arrange- ment.

Background Pulse wave velocity(PWV) is a marker of arterial stiffness, which represents sub-clinical atherosclerosis. Pulsatile stress and high-sensitivity C-reactive protein(hs-CRP) are associated with arteriosclerosis. However, there is no prospective data confirming whether changes in pulsatile stress and inflammatory markers affect the progression of arterial stiffness. The aim of this study was to investigate the relationships over time between the effects of changes in pulsatile stress and hs-CRP, and arterial stiffness progression during a 2-year follow-up. Methods We performed a longitudinal study involving 3978 participants. All participants underwent a physical examination in 2010–2011 and 2012–2013, during which we measured participants’ hs-CRP levels, brachial–ankle pulse wave velocity(ba PWV), and pulsatile stress. Results Baseline hs-CRP was correlated with ba PWV(r = 0.18, P = 0.000);however the correlation was weaker than that with systolic blood pressure(r = 0.65), pulsatile stress(r = 0.57), and rate-pressure product(r = 0.58). Multiple linear regression analysis demonstrated that changes in pulsatile stress, mean arterial pressure, and low-density lipoprotein-C(LDL-C) were positively correlated with changes in ba PWV, with correlation coefficients of 0.27, 0.25, and 0.07, respectively, but not with changes in hs-CRP. Moreover, each 100-a U increase in pulsatile stress, 1 mm Hg increase in mean blood pressure, and 1 mmol/L increase in LDL-C was associated with a 3 cm/s, 4.78 cm/s, and 17.37 cm/s increase in ba PWV, respectively. Conclusions Pulsatile stress increases are associated with arterial stiffness progression, but that changes in hs-CRP had no effect on arterial stiffness progression. Hs-CRP may simply be a marker of inflammation in arterial stiffness and has no association with arterial stiffness progression.

Co-Pd bimetallic catalysts immobilized with four kinds of resins with different specific areas were prepared by means of the solvated metal atom impregnation (SMAI) method. The results of the XRD and the magnetic measurement showed that as the specific area of the resin increased, the particle sizes of Co and Pd on the catalysts with the same metal content decreased, so the catalytic activity of the catalysts for the hydrogenation of diacetone alcohol as well as the reduction of oxygen on the fuel cell electrode increased. Below 140 , the conversion of diacetone alcohol increased as the reaction temperature increased, and above 140 , the conversion decreased because of the rupture of the resin.

Three novel lanthanide-IN coordination polymers [Ln（IN）3（H2O）2], （Ln = Sm 1, Dy 2, Eu 3; IN = isonicotinate） have been hydrothermally synthesized and characterized by FT-IR spectra, elemental analysis and Tg analysis. Single-crystal X-ray diffraction shows that 1, 2 and 3 are isostructural. Crystal data for 1： monoclinic, space group C 2/c, a = 15.8384（14）, b = 14.2662 （12）, c = 9.5073（7） A, β = 97.705（4）°, V = 2128.8（3） A^3, Z = 4, Dc = 1.724 g/cm^3, F（000） = 1084 , μ = 2.806 mm^-1 and R = 0.0226; Crystal data for 2： monoclinic, space group C 2/c, a = 15.7890（3）, b = 14.1356（6）, c = 9.5152（3） A, β= 97.899（2）°, V = 2103.52（12） A^3, Z = 4, Dc = 1.784 g/cm^3, F（000） = 1100, μ = 3.601 mm^-1 and R = 0.0406; Crystal data for 3： monoclinic, space group C 2/c, a = 15.802（5）, b = 14.242（4）, c = 9.513（3） A, β = 97.695（5）°, V = 2121.8（10） A^3, Z = 4, Dc = 1.735 g/cm^3, F（000） = 1088 ,μ = 3.004 mm^-1 and R = 0.0273. In the three compounds, the Ln（Ⅲ） centers are eight-coordinated with antiprismatic geometry. The Ln（IN）3（H2O）2 unit connects mutually to form a one-dimensional double zigzag chain via isonicotinate oxygen bridging. The infinite chains are further linked by inter-chain hydrogen-bonding to form a three-dimensional supramolecular network.

A pilot-scale Orbed oxidation ditch was operated for 17 months to optimize nitrogen removal from domestic wastewater of average COD to total nitrogen ratio of 2.7, with particular concern about the roles of dissolved oxygen （DO）, mixed liquor suspended solids （MLSS） and return activated sludge （RAS） recycle ratio. Remarkable simultaneous nitrification and denitrification （SND） was observed and mean total nitrogen （TN） removal efficiency up to 72.1% was steadily achieved, at DO concentration in the out, middle and inner channel of 0.1, 0.4 and 0.7 mg/L, respectively, with an average M LSS of 5.5 g/L and RAS recycle ratio of 150%. Although the out channel took the major role in TN removal, the role of middle channel should never be ignored. The denitrification potential could be fully developed under low DO, high MLSS with adequate RAS ratio. The sludge settleability was amazingly improved under low DO operation mode, and some explanations were tried. In addition, a scries of simplified batch tests were done to determine whether novel microorganisms could make substantial contribution to the performance of nitrogen removal. The results indicated that the SND observed in this Orbal oxidation ditch was more likely a physical phenomenon.

Nanoscale Pd/Fe bimetallic particles were synthesized with an efficient method to dechlorinate o-chlorophenol. The nanoscale Pd/Fe particles were determined by transmission electron microscopy and BET specific surface area analysis. Most of the particles are in the size range of 20—100 nm. The BET specific surface area of synthesized nanoscale Pd/Fe particles is 12.4 m 2/g. In contrast, a commercially available fine iron powder(g. Batch studies demonstrated that the nanoscale particles can effectively dechlorinate o-chlorophenol. The dechlorination reaction takes place on the surface of synthesized nanoscale Pd/Fe bimetallic particles in a pseudo-first order reaction. The surface-area-normalized rate coefficients(k_ SA) are comparable to those reported in the literature for chlorinated ethenes. The observed reaction rate constants(k_ obs) are dominated by the mass fraction of Pd and the mass concentration of the nanoscale Pd/Fe particles.

AIM: To investigate the protective effect of magnesium isoglycyrrhizinate(Mg Ig) on excessive hepatectomy animal model and its possible ***: We used the standard 90% hepatectomy model in Sprague-Dawley rats developed using the modified Emond's method,in which the left,middle,right upper,and right lower lobes of the liver were removed. Rats with 90% liver resection were divided into three groups,and were injected intraperitoneally with 3 m L saline(control group),30 mg/kg(low-dose group) and 60 mg/kg(high-dose group) of Mg Ig,respectively. Animals were sacrificed at various time points and blood was drawn from the vena cava. Biochemical tests were performed with an automatic biochemical analyzer for the following items: serum alanine aminotransferase(ALT),aspartate aminotransferase(AST),glutamyl endopeptidase,total bilirubin(TBil),direct bilirubin(DBil),total protein,albumin,blood glucose(glu),hyper-sensitivity C-reactive protein,prothrombin time(PT),and thrombin time(TT). Postoperative survival time was observed hourly until death. Hepatocyte regeneration was analyzed by immunohistochemistry. Serum inflammatory cytokines(IL-1,IL-6,IL-10,and i NOS) was analyzed by ELISA. STAT3 protein and m RNA were analyzed by Western blot and quantitative reversetranscription PCR,***: The high-dose group demonstrated a significantly prolonged survival time,compared with both the control and the low-dose groups(22.0 ± 4.7 h vs 8.9 ± 2.0 vs 10.3 ± 3.3 h,P = 0.018). There were significant differences among the groups in ALT,glu and PT levels starting from 6 h after surgery. The ALT levels were significantly lower in the Mg Ig treated groups than in the control group. Both glu and PT levels were significantly higher in the Mg Ig treated groups than in the control group. At 12 h,ALT,AST,TBil,DBil and TT levels showed significant differences between the Mg Ig treated groups and the control group. No significant differences in hepatocyte regeneration were fo
