The influence of different concentration of oxalic acid matrix on elemental inductively coupled plasma mass spectrometry （ICP-MS） has been investigated. It has been proved that the sensitivity of analytes can be significantly enhanced by adding small amounts of oxalic acid medium with adjusted nebulizer flow-rate gas, especially for the elements with ionization potential between 9 and 11 eV. Oxalic acid, as an enhancement agent, can be used to compensate the signal depression caused by inorganic matrix and to improve the detection limits about two to eight times, for the hard-to-ionize elements in ICP-MS determination.

关键词： ICP-MS oxalic acid enhancement effect.

该文研究了原花青素(oligomeric proanthocyanidins,OP)对长时间、大强度运动导致的心肌损伤的保护作用及其潜在机制。Wistar大鼠进行连续6周过量游泳运动训练,其中2组大鼠每天分别灌胃50 mg/kg OP(OP50组)和100 mg/kg OP(OP100组),模型组(model,Mod)灌胃等体积生理盐水,正常组(normal,Nor)作为对照。结果表明,Mod组血清中运动性心肌损伤标记物乳酸脱氢酶(lactate dehydrogenase,LDH)、肌酸激酶(creatine kinase,CK)及心肌肌钙蛋白I(cardiac troponin,cTnI)显著升高,心肌组织出现明显病理形态,呈现明显炎性细胞浸润;OP50及OP100组中LDH、CK及cTnI显著下调,心肌组织病理变化明显减轻(P<0.05)。心肌组织中,Mod组丙二醛(malondialdehyde,MDA)明显上升,抗氧化物酶谷胱甘肽(glutathione,GSH)及超氧化物歧化酶(superoxide dismutase,SOD)下降,核因子E2相关因子2(nuclear factor erythroid-2 related factor 2,Nrf2)/血红素加氧酶-1(hemeoxygenase-1,HO-1)(Nrf2/HO-1)抗氧化应激信号通路中关键蛋白的表达量显著下降;OP50及OP100组中MDA含量显著下调,GSH及SOD显著上调,Nrf2/HO-1通路中蛋白表达量显著增多(P<0.05)。Mod组血清及心肌中炎症指标肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)、白细胞介素-6(interleukin-6,IL-6)和白细胞介素-1β(interleukin-1β,IL-1β)含量明显上升,硫氧还蛋白互作蛋白/NOD样受体热蛋白结构域相关蛋白3(thioredoxin-interacting protein/NOD-like receptor thermal protein domain associated protein 3,TXNIP/NLRP3)炎症反应信号通路中关键蛋白的表达量显著上升;OP50及OP100组中炎症因子含量均显著下调,OP100组中TXNIP/NLRP3通路中蛋白表达量显著降低(P<0.05)。综上所述,补充OP对大鼠运动性心肌损伤具有明显的保护作用,且这种保护机制与增强心肌Nrf2/HO-1抗氧化通路及抑制TXNIP/NLRP3炎症反应信号通路有关。

Colloid gold nanoparticle-based layer-by-layer amplification approach was applied to enhance the electrochemical detection sensitivity of DNA hybridization at carbon nanotube modified carbon paste electrodes （CNTPEs）. Streptavidin was immobilized onto the surface of CNTPEs, and the conjugation of biotin labeled target oligonucle,otides to the above immobilized streptavidin was performed, followed by the hybridization of target oligonucleotides with the gold nanoparticle-labeled DNA probe and then the layer-by-layer enhanced connection of gold nanoparticles, on which oligonucleotides complementary to the DNA probe were attached, to the hybridization system. The differential pulse voltammetry （DPV） signal of total gold nanoparticles was monitored. It was found that the layer-by-layer colloidal gold DPV detection enhanced the sensitivity by about one order of magnitude compared with that of one-layer detection. One-base mismatched DNA and complementary DNA could be distinguished clearly.

关键词： Carbon nanotubes carbon paste electrode gold nanoparticles layer-by-layer amplifycation sensitivity.

The microstructure of the precipitated phases of ***3Zn1Zro.2 alloys with long-period stacking ordered structure before and after heat treatment is discussed. The corrosion properties of the as-cast （F）, solid-solution （T4） and aging-treated （T6） alloys in 1% NaC1 solution are studied. The hydrogen evolution and electrochemical measurements display that the as-cast ***3Zn1Zro.2 alloy with the continuous network eutectic phase exhibits the greatest corrosion resistance, while T6 sample with some needle-like phases and the particle phases is the worst among the three alloys. It is proposed to be mainly related to the amount, composition, microstructure and distribution of the precipitated phases.

A simple process for the deposition of CulnSe2 thin films was described. The CulnSe2 compound was prepared by selenization of Cu-In alloy precursors, which were electrodeposited at a constant current. The selenized precursors were compacted and then annealed. The films were characterized by X-ray diffractometry （XRD）, scanning electron microscopy （SEM） and energy dispersive spectroscopy （EDS）. The results indicate that single-phase CulnSe2 is formed at 250℃ and its crystallinity of this phase is improved as the annealing temperature rises. The losses of In occur in selenization process. The dense CulnSe2 film with comparatively smooth surface can be obtained by compaction under the pressure of 200 MPa.
