主要研究结果如下：建立了桃的稳定可靠的AFLP分析体系：高质量的基因组DNA是AFLP分析体系的关键步骤；E+0/M+0或E+0/M+C引物组合对预扩增条带数的影响不显著；选择性扩增引物组合E+2/M+3和E+3/M+3都可用于基因组的研究，但是前者的多态性高于后者；银染显色法具有成本低、检测时间短、避免同位素污染等优点，是一种安全、快速、有效的方法。

Methods PCR-SSCP was used to detect the expressions of P53、 N-ras、TGFα、P16 genes in variable nodules in 23 patients with multinodular hepatocellullar carcinomas, two pieces of inconsecutive tumor tissues in 20 patients with single nodular hepatocellullar and normal hepatic tissues in 10 healthy people N...

应用银染PCR-SSCP技术比较23例多结节性肝癌组织各结节中P53、 N-ras、TGFα、P16基因的表达情况并进行统计学处理。20例单发肿瘤病人的两块不相连的肿瘤组织作为阳性对照组，10例健康肝组织作为正常对照组。

This paper reviews the conventional models for the formation of marginal compositional reversals,including wall-rock contamination,multiple injection,compositional stratification of magma,high degree of supercooling,crystal settling of phenocrysts,flow differentiation,compositional convection and upward decrease in amount of intercumulus liquid.

朱丹，罗泰义，宋谢炎，徐义刚，陶琰，黄智龙，基性-超基性岩浆成岩和成矿过程中Soret效应的研究进展综述了当前对基性-超基性岩床和层状岩体的边缘反转现象的传统解释模型，包括围岩混染、岩浆多期注入、岩浆分层、过冷却、晶体沉降、流动分异、结晶和成分对流以及逐渐减少的颗粒间熔体量。

objective to study the effects of active carbon nanoparticles on the genotoxicity and teratogenicity of mitomycin c.methods using pce micronuclear test, chinese hamster lung cell chromosome aberration experiment and rat teratogenicity, to observe the toxicity of free mmc and the mmc absorbed onto acnp on heredity and reproduction.

目的 检测纳米活性炭对丝裂霉素的遗传毒理及生殖毒理学效应的影响。方法采用小鼠骨髓嗜多染红细胞微核试验、中国仓鼠肺细胞染色体畸变试验及致畸试验对受试物acnp-mmc进行遗传毒性及致畸性检测。

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.

许多的载体，病毒载体和非病毒载体以前已广泛应用，病毒载体主要包括腺病毒，逆转录病毒，腺相关病毒等；但病毒载体在安全性方面存在潜在的危险；免疫原性比较强，注射到机体后很快会被机体的免疫系统排斥，当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应；非病毒载体目前常用的有脂质体及多聚阳离子聚合物；但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性，转染效率较低且易被网状内皮系统吞噬，基因表达时间短；因此研制新型的非病毒载体已成为研究的热点，纳米颗粒具有小尺寸效应，表面效应，随着颗粒直径变小，比表面积将会显著增大，故具有很高的化学活性，因而纳米成为了最有应用前景的非病毒载体。

The cell in acidic situation presented a degenerative chang-ment,such as an increased lipid drop and empty cavity in the cell plasma,a py-knotic nuclei,the dilatation of the endoplasmic reticulum and Golgi saccules,mi-tochondrial swelling the number of ribose decrease,and the ribose dissociated inthe plasma,a lot of swallowing cavity,the fibric material decreased accompany-ing with the acid being stronger.

随培养基pH逐渐下降，上述过程因受酸性阻抑而延缓，细胞增殖速度也受影响，处于酸性环境中的软骨细胞呈退行性变化，表现为细胞浆内脂质颗粒与小泡增多、细胞核皱缩、核仁浓染、内质网线粒体膨胀、核糖体数目减少，且与粗面内质网结合的少，游离在胞浆中的多。

My first article for Screen Power Magazine, which is to this day is the official magazine of Jackie Chan, was a DVD review of the Hong Kong actioner Gen-X Cops, starring Nicholas Tse and Daniel Wu.

我的第一篇文章为屏幕力量杂志，在对这天是Jackie Chan 正式杂志，是香港actioner Gen X 警察的DVD 回顾，担任主角Nicholas Tse 和丹尼尔吴。
