外物

There are moments when my brain feels like a warehouse filled with miscellaneous bric-a-brac. Painting should be a way to open the doors of this warehouse, but when I try to represent these objects on canvas, I see they have disappeared without a trace. Apart from the vertiginous and addictive feeling they impart, all that remains before me is emptiness.

有一瞬间，我仿佛觉得自己的脑袋是一栋堆满了杂物的库房，画画就像是推开了这间仓库的大门，当我在平面上试图呈现那些杂乱的物什的时候，发现它们就在这时候消失得无影无踪，除了那些物什所散发出令人晕眩、使人沉迷的气息外，眼前只是一片空旷。

The prolactin gene was studied as a candidate gene for the prolificacy of Small Tail Han sheep. Single nucleotide polymorphisms of exon 1 to exon 5 of PRL gene were detected in high fecundity breeds and low fecundity breeds (Dorset, Texel and Corriedale sheep) with five pairs of primers by PCR-SSCP.

设计5对引物，采用PCR-SSCP技术检测催乳素（prolactin，PRL）基因外显子1至外显子5在高繁殖力绵羊品种和低繁殖力绵羊品种（多赛特、特克塞尔和考力代）中的单核苷酸多态性，同时研究该基因对小尾寒羊高繁殖力的影响。

Polymorphism was detected for exon 3 of BMP4 gene in four sheep breeds. For exon 3, three genotypes were detected in four sheep breeds. In Small Tail Han, Chinese Merino, Corriedale and South African Mutton Merino sheep, frequency of genotype AA was 0.017, 0.216, 0.115, 0.429, frequency of genotype AB was 0.102, 0.317, 0.269, 0.500, frequency of genotype BB was 0.881, 0.467, 0.616, 0.071, respectively. Sequencing revealed one singlenucleotide mutation C→A at 305 bp of exon 3 of BMP4 gene in genotype BB in comparison to genotype AA, and this mutation resulted in an amino acid change of alanine→aspartic acid.

对于外显子3的引物，在4个绵羊品种中都检测到3种基因型；统计结果表明：小尾寒羊、中国美利奴绵羊、考力代绵羊、南非肉用美利奴绵羊AA基因型频率分别为0.017、0.216、0.115、0.429，AB基因型频率分别为0.102、0.317、0.269、0.500，BB基因型频率分别为0.881、0.467、0.616、0.071；测序结果表明：BB型和AA型相比在BMP4基因外显子3第305位碱基处发生C→A的突变，该突变导致氨基酸由丙氨酸改变为天冬氨酸；BB型小尾寒羊平均产羔数分别比AB型和AA型多0.61只（P.05）和1.01只（P.05）。

Methods We collected 43 microtia cases' peripheral blood and extract genome DNA. Design primers of three exons of the GSC, then sequence after PCR amplification and depuration sequencing.

采集43例小耳畸形患者的外周血提取基因组DNA，对GSC基因的三个外显子分别设计引物，经PCR扩增纯化后直接测序。

It is suggested that the emulsify is formed when the oil on the water is stretched and stacked repeatedly by the wave, during which the water is mixed with the oil and entrain into the oil; particle asphaltene forms machinery protection film between oil and water, which stabilizes the water in the oil; the asphaltene film is formed through the accumulation when the water cohere; the resin of high viscosity can intensify the film.

通过对文献资料数据和不同观点进行分析及油水运动特点的实验观察，对溢油乳化物形成机制提出新的见解认为：乳化物是原油在波浪作用下反复拉伸和堆积中发生油水混合、水被夹带入油中而形成；颗粒态沥青质在水滴外形成机械保护膜将其稳定，它是水滴凝聚受阻时在油水界面积累而成，胶质的高粘性强化保护膜起到辅助作用。

Cellulose effusion can be found from epicardium to pericardium, it is typical fibrinous pericarditis

从心外膜表面直到心包可见细小的纤维素性渗出物的沉积物，这是纤维素性心包炎的典型表现

In this study we use the oligomers of amino ethylene series as matrix and introduce dithiocarbamate group to adsorb merely heavy metal ions. Because of its special structural characteristics , dithiocarbamate can combine with a great number of heavy metal ions to produce insoluble complex compound except for alkali metals and alkaline earth metals.

本研究系将氨基乙烯系列之寡聚物(oligomers of amino ethylene series)当做基质引入只对重金属离子具有特殊螯合能力之荒酸盐，除了与碱金属及碱土族外荒酸盐与其他重金属离子都能形成不溶性错合物。

Methods The total RNA of leucocyte was extracted 43 allergic vasculitis patients and 24 normal subjects before and after treatment with Trizol reagent and the integrity and concentrations of HLA-DRw53 gene mRNA were determined by agarose gel electrophoresis and UV spectrophotometer after denatured with 1% formaldehyde, the product was transcribed into complementary retroviral synthetic deoxyribonucleic acid, and sequence-specific primers were designed based on the sequences of second HLA-DRw53 gene exon and housekeeping gene glyceraldehyde phosphate-dehydrogenase cDNA.

利用随机引物逆转录合成互补脱氧核糖核酸，根据HLA-DRw53基因第二外显子序列和管家基因人磷酸甘油醛脱氢酶的cDNA序列设计序列特异性引物。检测43例变应性血管炎患者治疗前后与24名正常人HLA-DRw53基因mRNA表达量的变化。

The primers of exon 1 and 2 of hircine GDF9 gene were designed on base of the sequence of ovine GDF9 gene.

本研究根据绵羊GDF9基因序列设计引物扩增山羊GDF9基因的外显子1和外显子2。

The products amplified by primer 2 had polymorphism. The sequencing results indicated that there were two nucleotide mutations( C→A and C→T )at exon 1183bp and 336bp of hircine GDF9 gene, but the two mutations did not cause amino acid change. The products amplified by primer 3 had polymorphism.

所设计的6对引物扩增产物中共有3对发现了多态，引物1经SSCP分析虽然没有发现多态但经克隆测序却在外显子1编码区前-4bp处检测到A→C的突变。
