The pcDNA〓-apoE〓 plasmid was transfected to SK-N-SH Neuroblastoma cell by liposome. It could be screened by G〓. The immunohistochemical assay was shown that neuroblastoma cell transfected by pcDNA〓-apoE〓 expressed the recombinant apoE protein.

Precursors of sulfates and alkali halides prepared in co-deposition process were mixed homogenously, annealed at high temperature and then formed CoO and NiO fibers, XRD, XPS, Raman and SEM were used to characterized the samples, the growth of these fibers might be a special LS mechanism: soluble precursors in molten salt decomposed gradually to form initial crystal nucleus and succeeding particles adhered to these nucleus and grew anisotropically in the special high temperature fluent medium, the higher decomposition temperature and solubility of the precursor are two key factors in this method, which are in favor of a longer growth process and result in larger sizes of the final metal oxides crystals.

以共沉淀方法生成硫酸盐与碱金属卤化物融盐的均匀混合前驱物，在高温下退火制备出了CoO和NiO的晶须，以XRD和XPS等对成份进行了分析，SEM分析了形貌特征，研究了不同前驱物热分解特性，认为本方法是一种简单的LS生长机制：可溶性前驱物于融盐中热分解后逐渐析出成核，后续的粒子附着在核上，在融盐环境下沿一定方向作准一维生长，其产物形貌之不同源于硫酸盐的高分解温度和在融盐中的可溶性，导致晶体生长过程中成核过程与生长过程竞争的结果对一般前驱物结果的偏移。

Moreover,the selective oxidation of primary and secondary alcohols to corresponding carbonyl compounds with the multinuclear copper complexes Cul-Cu4 as catalysts have been conducted using TBHP and O_2/TEMPO,respectively.Among them,the copper complex Cu3 showed the best performance.On the performances of the two classes of oxidants,benzylic and heterocyclic alcohols could be effectively oxidized to carbonyl compounds.Specifically,the secondary alcohols could be effectively oxidized to ketones with excellent selectivity up to 100%in the presence of TBHP and the allylic alcohols could be effectively oxidized to aldehydes in the presence of O_2/TEMPO system.

实验结果还表明，在TBHP或O_2/TEMPO存在下，各配合物催化剂均能使各种取代芳香伯/仲醇以及杂环醇等以不同程度的转化率和选择性转化成相应的醛或酮，其中，配合物Cu3在O_2/TEMPO存在下可使苯甲醇和烯丙醇等以较高转化率和近100%的选择性转化成相应的醛，而对其它芳香醇和脂肪伯/仲醇等的催化性能则较差；在TBHP存在下，配合物Cu3则可使1-苯乙醇和其它仲醇以较高转化率和近100%的选择性转化为相应的酮，但对各类其它伯醇选择氧化的性能相对较差。

Materials and Methods: Six patients with left frontal lobe tumors (4 gliomas, 1 germinoma, 1 intra-axial cavernoma) close to Brocca and Wernicke language areas were studied. BOLD and DTI were performed on a 3.0T magnet GE Signa Excite~(? HD_X, BOLD using the word association paradigm developed in Part I and DTT technique developed in PartII. Language activation maps and fiber tracts were superimposed upon high resolution T1 weighted anatomic images of the brain for displaying the relationship between tumor, language functional areas and white matter tracts.
