川中古隆起蓬莱气区灯影组属超深地层.为适应超深地层高温高压环境、提高钻井速度,部分井采用油基泥浆钻井,因此,明确油基与水基泥浆环境下的测井响应差异对于储层测井评价十分重要.为此,本文选择两口井(A井和B井)开展水基泥浆替换油基泥浆实验,并结合岩心及试气资料,明确了油基泥浆和水基泥浆测量环境条件下常规测井和电成像测井响应特征差异.分析结果表明:(1)油基泥浆条件下,扩径段自然伽马、声波时差和补偿中子测井曲线值不受泥浆性质影响;补偿密度测井曲线值略低,且在扩径明显处差异大;未扩径段补偿密度测井曲线值不受泥浆环境影响;(2.油基泥浆条件下阵列感应测井电阻率对水层敏感,在水层处存在负差异现象;(3)水基与油基泥浆条件下双侧向测井电阻率明显高于阵列感应测井电阻率;(4)油基泥浆成像测井可展现与水基泥浆成像测井同等地层信息,不易识别井眼崩落和应力释放缝.结论认为,油基泥浆环境下,扩径段需对补偿密度曲线值进行校正,成像测井可准确识别地质特征,并用于储层评价.

In the theory of traditional Chinese medicine, aging is mainly thought renal deficiency caused renal failure, mainly involving decline of kidney-Yang and deficiency of kidney-essence. Huanshaodan, a Chinese traditional preparation for kidney-replenishing essence, was used to be the preparation for reinforcing renal deficiency and preventing aging for aged people. OBJECTIVE： To observe the effects of Huanshaodan on swimming durance and the abilities of catalase （CAT） in serum and monoamine oxidase-B （MAO-B） in brain tissue as well as in vitro anti-oxidative ability of aging mouse. DESIGN： A controlled animal experiment. SETTING： College of Basic Medicine, Hunan university of Traditional Chinese Medicine. MATERIALS： Fifty-four healthy NIH mice, aged 18 months old, of either gender, weighing （48.9±5.4） g, and one SD male rat, aged 16 months old, weighing 51.7 g, were provided by Animal Experimental Center, Hunan university of Traditional Chinese Medicine. Thirty NIH mice were randomly chosen for swimming test, and divided into experimental group and control group, with 15 in each; The other 2. NIH mice were used for enzyme activity assay, and also divided into experimental group and control group, with 12.in each. SD rat was used for in vitro anti-oxidative ability test, Huanshaodan water decoction was composed of Cheqianzi, Wuweizi, Huaishan, Danggui, Huangbai, Shudi, Baizhi, Niuxi, Baishen, Tusizi, Buguzhi, Roucongrong and Heshouwu 13 Chinese herbs. METHODS： This study was carried out in the Second Laboratory, {2. of Biochemistry, Hunan university of Traditional Chinese Medicine in June 2.06. Swimming and enzyme activity assay： Mice in the two experimental groups were intragastrically administrated with l0 μL/g Huanshaodan water decoction. Mice in the two control groups were intragastrically administrated with the same amount of normal saline. All the mice were intragastrically administrated for 5 days, and they were free to access to medicine in the other 2.d

＜正＞Project scheduling problem is mainly to determine the schedule of allocating resources in order to balance the total cost and the completion *** paper chiefly uses chance theory to introduce project schedul- ing problem with mixed uncertainty of hybrid variable. Firstthree types of hybrid single-objective program- ming models as expected value model,maximax chance- constrained model and dependent chance-constrained model are established to meet different management re- quirements,then they are extended to hybrid multiobjec- tive programming model and hybrid goal programming model.

目的基因沉默通过抑制细胞增殖,减少肿瘤细胞的黏附和侵袭等,对部分肿瘤细胞有抑制作用。本研究探讨黏着斑激酶(focal adhesion kinase,FAK)基因沉默对胃癌SGC-7901细胞体外增殖和迁移影响及作用机制。方法采用实时荧光定量PCR法检测人胃癌SGC-7901细胞中FAK基因的表达水平,然后将FAK-siRNA重组质粒转染到SGC-7901细胞中,采用实时荧光定量PCR和蛋白质印迹法鉴定FAK基因沉默效果;采用CCK-8试剂盒和Transwell小室法分别检测FAK基因沉默对胃癌SGC-7901细胞增殖和迁移影响;蛋白质印迹法检测FAK基因沉默后其下游相关HGF信号通路分子表达情况。结果 FAK在胃癌SGC-7901细胞中高表达,FAK-siRNA转染入FAK基因高表达的胃癌SGC-7901细胞后,FAK表达被明显下调,空白对照组、阴性对照组和si-FAK转染组A值分别为1.512.0.009、1.462.0.034和1.2.1.0.004,差异有统计学意义,F=2.4.083,P1。细胞增殖和细胞迁移能力明显降低,P1。FAK基因沉默后可抑制PI3Kp85a、AKT和GRB2.白表达,P1。HGF表达无明显影响,但可明显抑制p-HGF表达水平,P1。结论 FAK可能通过激活HGF信号转导通路,促进胃癌SGC-7901细胞的体外增殖和迁移。
