AIM： To determine whether midkine （M/O and its truncated form （tMK） contribute to gastric tumorigenesis using in vitro and in vivo models. METHODS： Human MK and tMt（ plasmids were constructed and expressed in BGC823 （a gastric adenocarcinoma cell line） to investigate the effect of over-expressed MK or tMK on cell growth and turmorigenesis in nude mice. RESULTS： The growth of MK-transfected or tMK- transfected cells was significantly increased compared with that of the control cells, and tMK-transfected cells grew more rapidly than MK-transfected cells. The number of colony formation of the cells transfected with MK or tMK gene was larger than the control cells. In nude mice injected with MK-transfected or tMK-transfected cells, visible tumor was observed earlier and the tumor tissues were larger in size and weight than in control animals that were injected with cells without the transfection of either genes. CONCLUSION： Over-expressed MK or tMtC can promote human gastric cancer cell growth in vitro and in vivo, and bMK has greater effect than MK. tMK may be a more promising gene therapeutic target compared with MK for treatment of malignant tumors.

Five novel SrⅡ-LnⅢ heterometallic coordination polymers based on pyridine-2,6- dicarboxylic acid （H2pda） and imidazole （im）, namely, [LnSr（pda）3（H2O）5]-Him·C2H5OH·3H2O （Ln = Nd （1）; Pr （2））, [Ln2Sr（pda）6（H2O）5]-4Him·C2H5OH·5H2O （Ln = Nd （3）; Pr （4））, and [ErSr（pda）3（H2O）4].Him-3.5H2O （5）, have been prepared and structurally characterized. X-ray crystallographic analyses revealed that these complexes display three varieties of l-D chain structures. Several types of hydrogen bonding interactions are found for 1-5, which connect the 1 -D chain structures to form 2-D suoramolecular networks.

研究企业"走出去"寻求更高技术对生产率提升具有重要意义。基于对外直接投资(OFDI)技术寻求动机视角采用中国OFDI企业数据对此实证研究。结果表明:(1)OFDI技术寻求动机越强跨国企业生产率越高,即向技术创新水平越高的国家投资越能够提高企业生产率。(2)OFDI技术寻求动机对企业生产率的影响不仅具有企业异质性而且在东道国与地区异质性上也存在差异。由此,本文认为向技术创新水平越高的国家投资寻求更高技术可成为提升企业生产率的重要途径;同时,企业实施"走出去"寻求技术应考虑异质性影响,做到分类实施。
