Methods Transmission electron microscope was used to observe the apoptotic morphology of the lens epithelial cells in 4 cases with senile cataract and in 2 mice with congenital cataract. The comparisons were made between the cataractous and normal transparent lens epithelial cells in human being and mice.

用透射电镜观察4例老年性白内障患者及2例先天性白内障小鼠晶状体上皮细胞凋亡的超微结构，并分别与同类正常晶状体上皮细胞超微结构进行比较。

The C18 known sequence, whose sequence had been known but function remained unknown, was expressed in cataractous lens epithelium but was not expressed in normal lens epithelium.

序列已知而功能未知的C18已知序列在白内障晶状体上皮有表达，但其在正常晶状体上皮中无表达。

Xenopus laevis Tadpole (1) Xenopus laevis Tadpole was capable of lens regeneration, which originated from the outer cornea.(2)The days of lens regeneration of Xenopus laevis Tadpole was earlier than Bufo Raddei Strauch Tadpole, The rate of regeneration of Xenopus laevis Tadpole was higher than Bufo Raddei Strauch Tadpole.(3)During Xenopus laevis lens regeneration the outer cornea cells proliferated, in the elongating cells the mitochondria became complicated and in the columnar cells the cisternal dilating of endoplasmic reticulum was ubiquity.

非洲爪蟾蝌蚪(1)再生晶状体来源于外角膜；(2)晶状体再生较花背蟾蜍蝌蚪晶状体再生时期早，再生率高；(3)电镜观察发现再生前期外角膜增殖，观察到晶状体上皮细胞和伸长细胞(进一步发育为晶状体纤维细胞)，伸长细胞中线粒体形状各异随着进一步的分化，细胞器逐渐消失；分化过程中晶状体上皮细胞粗面内质网增多，并且内质网扩张普遍存在。

Moreover, expression of a constitutively active form of Notch4 in mammary epithelial cells inhibits epithelial differentiation and leads to tumor formation in this organ.

再者，乳腺上皮细胞中一种持续活化形式Notch4的表达也能抑制上皮细胞的分化，从而导致肿瘤形成。

Results Cribriform and trumpet-shaped epithelial stomata were scattered on the pineal capsule.

结果 在大鼠松果体囊表面发现存在筛状囊上皮孔和喇叭口状囊上皮孔。

This normal thyroid follicle is lined by a cuboidal follicular epithelium with cells that can add or subtract colloid depending upon the degree of stimulation from TSH released by the pituitary gland.

正常甲状腺滤泡内衬立方上皮。这些上皮细胞可分泌或重吸收胶质，这有赖于垂体分泌的TSH的刺激程度。

However, there were a great number of inflammatory cells, epithelial proliferation, partial breakage and defluvium of the airway epithelium in the bronchus, below the vessel mucous membrane and around lung tissues in the model control group.

正常对照组小鼠气道无明显炎症改变；模型对照组小鼠支气管、血管粘膜下和周围肺组织有明显炎症细胞浸润、气道上皮增生、气道黏液增多、气道上皮部分断裂脱落；细胞移植组小鼠气道炎症明显减轻。

The high rates of metabolism and nutrient utilization in the gut are directly linked to the high rates of proliferation, protein secretion, apoptosis and desquamation of various epithelial and lymphoid cells within the mucosa (Burrin and Stoll, 2003), all of which are a key feature of the post-weaning period.

肠道代谢和营养物质利用的高效率直接与粘膜内不同的上皮和淋巴细胞的本身增殖、蛋白分泌、细胞死亡和脱落有关，这些上皮和淋巴细胞对断奶后仔猪生长和发育都很关键。

In the late proliferative and secretive phases, expression of ERα in stromal cells significantly decreased to the level observed in the desquamative phase Differently, no clear expression of ERβ was detected in stromal cells in the late proliferative phase. However, its expression appeared again in the secretive phase.

结果显示： 1ERα和ERβ在恒河猴子宫内膜的上皮细胞、基质细胞中均有表达，其表达水平在正常月经周期中发生周期性变化：上皮细胞中两种受体的表达水平从增殖期开始逐渐升高，到增殖晚期最高；分泌期开始下降，直到月经期的水平。

The negative correlation was observed between S100A4 expression and Ecad expression (r=-0.385, P.05) CONCLUSION: The correlated expression of S100A4 and Ecad is closely related to the development of epithelial ovarian carcinoma,which is valuable markers in predicting biological behavior and trend of metastasis in epithelial ovarian carcinoma.

S100A4和Ecad的相关表达与上皮性卵巢癌的发生发展关系密切，是判断上皮性卵巢癌生物学行为、预测侵袭转移的重要指标。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
