Birdlike, he retired at dusk, lying on the bare floor with a wooden block under his head like a pillow.

如鸟一般，他黄昏即栖，躺在空无一物的地板上，头下放着一块如枕头般的木块。

Packaging gravure press on the substrate by business card printing and membership card production unit of distance is long, plus the fact that, in the meantime drying can easily lead to changes in tone changes and expansion, in General, equipped with automatic alignment device scanning head read printing on the overprinter tag.

包装凹印机上承印物通过制卡和会员卡制作机组间的距离较长，加之在其间进行干燥，容易引起张力变化和伸缩变化，一般都装有自动套准装置，由扫描头读取印品上的套印标记。

Failure to recognize one's own disease, a usual parietal syndrome.

无法认出某人的特有物的疾病，是一种常见的头顶骨上的症状。

It is used to some extent in pharmaceutical industry (used as special catalyst to produce antibiotics) and chemical industry, esp. in production of cephalosporin (whose effect is better than boron trifluoride ethyl ether complex compound), and also used for most advanced science, such as abstraction of fuel with high energy and of isotope B10 as well as chemical reagent.

在制药工业(在医药上作为生产抗生素的专用催化剂)、化学工业等行业中都有不同程度的使用，尤其在头孢抗菌药类，效果优于三氟化硼乙醚络合物，亦用于尖端科学，如高能燃料的提取及提取同位素B10，也可用作化学试剂

The PSCA_3 fragment was selected for its superior expression level in eukaryotic cells.Then the sig-PSCA_3-Fc-GPI genetic fragment was cloned into pVAX1-neo-IRES-GM/B7 vector to construct the final immunological inhanced DNA vaccine pVAX1-PSCA_3-FcGB. Immunofluorescence and flow cytometry were used to confirm the expression of PSCA_3 fragment by transfected into Cos7 cell.Finally,the anti-tumor effect of pVAX1-PSCA_3-FcGB was tested in murine prostate cancer model generated by RM-1 cell line.The animal was immunized with pVAX1-PSCA_3-FcGB DNA vaccine by intramuscular injection plus electroporation,pVAX1 and pVAX1-PSCA_1-FcGB plasmid were used as control.The inhibitory effect of tumor was investigated by observion of forming time,volume and inhibition ratio of tumor.Results:DNA sequencing conformed that the heterological PSCA fusion antigen fragment which was synchronized by overlapping-extending-PCR,was consistent to design.Enzyme digestion analysis showed that the 1 to 4 copies heterological PSCA fusion antigen fragments were constructed successfully.

方法(1)检索GenBank，选择包含人主要T细胞抗原表位序列的人PSCA基因片段，应用异种化抗原设计技术，保留人T细胞抗原表位，设计异种化PSCA融合抗原片段；(2)根据核酸序列按中心模板法设计引物，应用重叠延伸PCR技术拼接合成异种化PSCA融合抗原片段基因，以PCR、限制性酶切和DNA序列测定法进行鉴定：(3)利用DNA限制性内切酶BssHⅡ和MluⅠ酶切后粘端互补的特点，采用同尾酶法构建1—4拷贝异种化PSCA融合抗原片段(PNCA_1-PSCA_4)，并将上述片段分别插入真核表达载体pCI-neo-Fc-GPI中，转染293T细胞，借助免疫荧光+流式细胞术考察插入片段表达效率，最终选定PSCA_3片段进行下一步研究；(4)将sig-PSCA_3-Fc-GPI基因片段自pCI-PSCA_3-Fc-GPI质粒上切下，插入pVAX1-neo-IRES—GM/B7载体中，构建免疫增效DNA疫苗pVAX1-PSCA_3-FcGB，并应用转染Cos7细胞+免疫荧光/流式细胞术方法鉴定其在真核细胞中的表达情况；(5)给8周龄雄性C57BL/6小鼠皮下种植RM-1细胞，制备小鼠前列腺癌模型，并采用股四头肌肌肉注射+电脉冲法(Electroporation，EP)接种DNA疫苗质粒pVAX1-PSCA_3-FcGB，同时接种pVAX1空载体质粒和pVAX1-PSCA_1-FcGB质粒作为对照，通过观察计算免疫动物的成瘤时间、肿瘤体积和抑瘤率，来评价该DNA疫苗在小鼠体内的抑瘤效果。
