Sulfate-centered Preyssler-type polyoxometalate was used as the precursor to react with transition metal cations and organic ligand for constructing inorganic-organic hybrid materials {H[Ni2（H2O）4（Htrz）3]2（KSsW30O110）}·18H2O （trz = 1,2,4-triazole）（1）, which was characterized by single crystal X-ray diffraction analysis, energy-dispersive X-ray （EDX）, power X-ray diffraction （PXRD）, IR spectra and thermogravimetric （TG） analyses. In 1, the cylindrical vacancy of the inorganic crown-type anion （SsW30Ouo） captures a K^＋ ion resulting in the anion {KS5W3oO110）^9-, which was further connected by dimeric [Ni2（H2O）4（Htrz）3]2 metal-organic units into an one-dimensional （1D） chain-like structure. These 1D chains are further packed to form a three-dimensional （3D） supramolecular structure via Hbonding interactions. Here, the sulfate-centered Preyssler-typepolyoxometalate was firstly used to coordinate with transition metal cations and introduced into the inorganic-organic hybrid materials. Electrocatalytic study indicates that compound I exhibits good electrocatalytic activity toward reduction of H2O2 and NO2^-.

目的:探讨改良早期预警评分结合血清脂肪酶水平判断急诊患者病情危重程度的价值。方法:对2015年2月至2018年2月601例急诊患者行改良早期预警评分评估,并测定血清脂肪酶水平,追踪患者临床结局。结果:改良早期预警评分、血清脂肪酶水平随着急诊患者病情程度加重而升高(P<0.05),死亡组改良早期预警评分、血清脂肪酶水平高于存活组(P<0.05)。改良早期预警评分与血清脂肪酶呈正相关(r=0.362,P<0.05),改良早期预警评分、血清脂肪酶、联合改良早期预警评分和血清脂肪酶预测急诊患者预后的曲线下面积(AUC)分别为0.778(95%CI:0.663~0.892,P=0.027)、0.855(95%CI:0.752~0.955,P<0.001)、0.892(95%CI:0.810~0.974,P<0.001),灵敏度和特异度分别为78.13%、73.11%;87.50%、66.26%;88.25%、79.21%。结论:改良早期预警评分、血清脂肪酶水平与急诊患者病情危重程度密切相关,两者联合检测可提高预后判断的准确性。
