The etiology of PCO is incompletely known. The surgical trauma might activate LECs in a wound-healing process. Several experimental studies showed that some agents have been effective in inhibiting LECs proliferation and differentiation, and also in development of PCO, such as anti-metabolites, nonsteroid antiphlogistic drugs, cyclosporin A.

大量的体外实验已经证实抗代谢药物如5-氟脲嘧啶、丝裂霉素、柔红霉素等，环孢霉素A等皆可抑制晶状体上皮细胞的增殖和分化，但这些药物对眼内其他正常组织的毒副作用限制了其临床应用。

Human hsp90 genes are usually constitutively expressed in most mammalian cell types and can be further induced by heat shock and mitogen.

热休克蛋白90（HSP90）在正常生长条件下细胞内就有较高水平的组成性表达，并可被热和丝裂原双重诱导。

There were 8 embryos single blastomere amplified, and the amplification success rate was 72. 7%(8/11); 3 embryos' not amplified; 2 embryos'showed preferential amplification , and the PA rate was 25%(2/8); and the 7 tubes of blank with washing cell solution were not contaminated. We transferred 3 unaffected embryos to the uterus. But unfortunately, blood hCG was negative after 2 weeks of transferring indicating no pregnancy.

共8枚胚胎的单卵裂球得到扩增，扩增成功率为72.7%（8/11），3枚未得到扩增，2枚发生了偏性扩增(preferentialamplification，PA)，PA的发生率为25%（2/8），细胞洗脱液空白对照7管均无污染发生。3枚诊断为正常的胚胎被移植入宫内，不幸的是，移植后2周，血hCG阴性，证明未妊娠。

Ontogenesis begins from the fertilized embryo. After the cells proliferation during the embryo cleavage, it enters the stage of blastoderm differentiation、 tissue and organ formation.

个体发育从受精卵开始，经过卵裂阶段的细胞增殖后，进入到胚层分化、组织和器官形成阶段。

Methods: AR and ER expression and its distribution in the preputial cells of 28 cases with different types of hypospadias were examined by radioligand binding assay.

通过受体的放射配基结合分析，对28例不同程度的先天性尿道下裂患儿外生殖器皮肤细胞内的AR、 ER的表达及细胞内的分布进行了测定。

After HIFU irradiation, the histopathological changes of lesions of liver and kidney mainly characterized as completely coagulative necrosis, cell debris, pyknotic nuclei.

HIFU损伤后，肝脏和肾脏治疗区的组织病理变化主要表现为细胞的完全性坏死，细胞结构完全破坏，胞浆均质状，细胞核变形、碎裂、固缩、溶解。

Simultaneously the disappearance of microvilli, vacuolization of cytoplasm, dispersion of nucleus and appearance of apoptotic body were observed under transmission electron microscopy. All these morphological changes are hallmarks of apoptosis.

凋亡细胞经荧光染色后表现为细胞核固缩、碎裂；透射电镜下观察发现细胞微绒毛丧失，胞内出现空泡，胞核解体及形成凋亡小体等典型的凋亡特征。

Embryo cells display a synchron cleavage rhythm during the cleavage stage, there is almost no gene transactivation, which is regulate and operated by the mRNAs and protein of oocyte.

卵裂阶段的胚胎细胞呈现同步化的分裂节律，鲜有基因转录活动，其发育由源自卵母细胞发生期间合成的蛋白质和mRNAs调控。

In the lytic cycle, this DNA then replicates inside the cell and is packaged within newly synthesized capsids,eventually being released by cell lysis.

在裂截周期中， DNA 在细胞内复制，包装在新合成的外壳中，最终由细胞裂解释放出来。

Methods Mouse endometrial epithelial cells were isolated and cultured,then it was cocultured with mouse embryos fertilized in vitro.

对小鼠子宫内膜上皮细胞进行分离、培养鉴定，然后与体外受精的小鼠胚胎进行共培养，观察共培养对小鼠胚胎卵裂率、孵化率以及囊胚期胚胎总细胞数的影响。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
