Dear editor,Deep vein thrombosis (DVT) is a common peripheral vascular disease, causing pulmonary embolism, post-venous thrombosis syndrome, chronic thrombotic pulmonary hypertension, and other complications.[1] The inferior vena cava filter (IVCF) implantation combined with adequate anticoagulation could lower the incidence of fatal PE to linical practice, the double inferior vena cava (IVC) malformation along with lower extremity DVT (LEDVT) is rarely seen.

Accumulating evidence indicates that a-amino-3-hydroxy-5-methylisoxazole-4-propionic acid receptors（AMPARs） are involved in the relapse to abused ***, the role of AMPARs containing the Glu R2 subunit in opiate addiction is still unclear. Glu R2-3Y,an interfering peptide, prevents the endocytosis of AMPARs containing the Glu R2 subunit. In this study, we explored the effect of intravenous injection of Glu R2-3Y on the acquisition, expression, and reinstatement of morphine-induced conditioned place preference（m CPP） in rats. We found that infusion of Glu R2-3Y（1.5 nmol/g） one hour before morphine during the conditioning phase inhibited the acquisition of m CPP, while an identical injection one hour before the post-conditioning test had no influence on the expression of m CPP. Injection of Glu R2-3Y（1.5 nmol/g） after m CPP extinction blocked the morphine-induced reinstatement of m CPP. Our results strongly support the hypothesis that inhibition of AMPAR endocytosis provides a new target for the treatment of opiate addiction.

A series of bis{oxo bis[heteroaromatic carboxylatodibenzyltin(Ⅳ)]} complexes {[(PhCH 2) 2Sn· (O 2CR)] 2O} 2[where R=2 furyl, 2 (2 furyl)vinyl, 2 (5 tert butyl)furyl, 2 thiophenyl, 2 pyridinyl, 3 pyridinyl , 4 pyridinyl, 3 indolyl, 3 indolylmethyl, 3 indolylpropyl] was synthesized by the reactions of heteroaromatic carboxylic acids with dibenzyltin(Ⅳ) oxide. All the complexes were characterized by elemental analysis, IR, and NMR spectra. The complexes were tested against two human tumour cell lines: MCF 7 and WiDr. The results show that they have higher activities in vitro . The crystal structure of bis{oxo bis[2 furylcarboxylatodibenzyltin(Ⅳ)]}(1) was determined by X ray diffraction. The crystal belongs to monoclinic space group P2 1/n, a =1 6641(2) nm, b =1 25073(18) nm, c =1 7193(3) nm, β= 101 951(2)° , Z=2, R 1=0 0446, wR 2=0 1100. Complex 1 is of a centrosymmetric dimer structure with a four membered central endo cyclic Sn 2O 2 unit in which the bridged oxygen atoms are tri coordinated. Each bridged oxygen atom also connects with an exo cyclic tin atom. The tin atoms are six coordinated and have a coordination geometry of a distorted octahedron. The exo cyclic tin atoms are five coordinated and have a coordination geometry of a monocapped trigonal bipyramid with a very similarly distorted mode. Four carboxylate ligands are divided into two types. The two of the four carboxylate ligands are bidentate and bridged to each pair of exo and endo cyclic tin atoms by using both the oxygen atoms. The other two are monodentate and bridged to each pair of exo and endo cyclic tin atoms but each utilizes one O atom only.

隐喻言说是《庄子》话语特色之一,其中不乏体现主体与其生存环境同构互动的精神生态隐喻。本文对此种隐喻进行界定并提出识别程序,选取《庄子》精神生态隐喻英译实例,探究何种叙事重构方法能将《庄子》原文有关精神生态的隐喻叙事内容更好地被译入语读者群接受并认可,进而将原文的精神生态内涵在异域文化中得以传递。《庄子》精神生态隐喻主要有喻体源于自然意象和非自然意象等两类。前者的英译可遵照选择性采用的诗化叙事重构方法,后者的英译宜采取人物事件再定位的语境重构策略。聚焦《庄子》中精神生态隐喻的译介叙事重构研究,可对以生态思想外译为导向的《庄子》英译实践与研究提供参考。

The sub-arc mantle that experienced hydrous melting is commonly characterized by refractory geochemical compositions. Nevertheless, minor lherzolites with fertile compositions have also been reported for mantle peridotites from subduction zone. The petrogenesis and mantle source of the lherzolites are still controversial. The New Caledonia ophiolite(Peridotite Nappe) has been regarded as an allochthonous body of forearc lithosphere. This is supported by refractory compositions of its dominant mantle rocks.A few isolated lherzolitic massifs have also been observed in the northern part of New *** lherzolites are compositionally similar to abyssal peridotites, with negligible subduction-related modification. Here, we present new comprehensive geochemical compositions, in particular highprecision Sr-Nd-Hf isotope data, for the lherzolites. The initial^(176) Hf/^(177) Hf ratios display moderate correlations with sensitive indicators for the extent of melting(i.e., olivine Fo, whole-rock Mg# and Yb contents in clinopyroxene) and whole-rock initial^(187) Os/^(188) Os ratios. Some samples have ancient radiogenic Hf isotopes and unradiogenic Os isotope compositions, implying the preservation of ancient depletion signals in the lherzolites. The Nd isotope compositions, together with trace elements and mineral micro-textures, suggest that the lherzolites have been overprinted by a recent melt-rock interaction event. The high equilibrium temperatures of the studied samples have been estimated by the twopyroxene REE thermometer, yielding temperatures of 1066–1315 ℃. The lherzolites have more depleted Nd-Hf isotope compositions and higher equilibrium temperatures than the New Caledonia *** indicates that the lherzolites may represent the residues of asthenosphere mantle trapped within the forearc region. Our studies on the New Caledonia lherzolites with ancient depletion signals suggest that ancient mantle domains in the convective mantle can be emplaced
