Genesis,development and metabasis of solid tumor have close relationship with tumor vessel angiogenesis; extracellular matrix degradation is the key point for tumorous infiltration and metabasis;the significant biology characteristic of tumor cell is the disorder of tumor cell differentiation and apoptosis.

骨巨细胞瘤血管生成是近年来研究热点，实体瘤的发生、发展及转移与肿瘤的血管生成密切相关；细胞外基质降解在肿瘤的浸润和转移中起到关键作用；肿瘤细胞的分化凋亡障碍与无限增殖能力是肿瘤细胞的重要生物学特征。

Results. Pleiotrophin immunoreactiity was seen in disc cells, endothelial cells, and in the extracellular matrix in most specimens of interertebral disc but was most prealent in ascularized tissue in prolapsed discs.

结果：多效蛋白表达在大多数标本的椎间盘细胞、内皮细胞和细胞外基质都得到了较好的表达，但表达最显著的还是在突出椎间盘的血管再生组织中。

Platelets were loaded with 13 mmol/L intracellular trehalose and freeze-dried in a formulation of 1 % bovine serum albumin and 1% trehalose. 40 days later, the numerical recovery of rehydrated platelets was about 85 %, the morphology of rehydrated platelets was intact and the aggregation percentage with thrombin (1U/mL) was 97.3%. 15Refs. In Chinese.

在13 mmol/L细胞内海藻糖和1 %牛血清白蛋白+1 %海藻糖细胞外保护剂同时存在的情况下，冻干保存40天的血小板复水后的数值恢复率约85 %，显微镜观察细胞形态完整，对1 U/ml凝血酶的聚集百分比为97.3 %。

Unable to reproduce outside a living cell, viruses reproduce only by subverting the genetic mechanisms of a host cell.

病毒在活细胞外无法繁殖，只能通过破坏寄主细胞的基因机制而得以繁殖。

OBJECTIVE: To investigate the preparation of bone acellular extra-cell matrix and to analyze its component.

目的 探讨脱细胞骨细胞外基质的制备，并对其进行有机成分分析。

This rapid inhibitory effect has also a larger calcium-dependent exocytosis reduction effect.

在细胞外液加入BIS，或用PTX孵育细胞24小时，可将皮质酮的抑制作用阻断。

RESULTS: Transplanted AS had a favorable fusion between tissue-engineered skin and self-skin on the 3rd day after grafting with a few of ingrowths of capillaries.

结果：AS组在移植第3天，移植的组织工程皮肤与自体皮肤能够很好地融合，有少量毛细血管长入移植物，皮肤移植物颜色与自体皮肤颜色接近；随着时间的延长，移植物中毛细血管的数量逐渐增多，表皮层清晰可见基底层、棘细胞层、颗粒层和角质层，角化现象加强，有角化物脱落；真皮层细胞数量增多，网架逐渐降解，分泌的细胞外基质成份增多；第14天，创面基本愈合；修复区皮肤颜色与正常皮肤颜色非常接近，瘢痕很小，无需进行二次植皮。

Much more prolongation ofsurvival term and improvement of survival rate,as well as appearance of a great dealof lymphocytes around pulmonary metastatic nodes and less pulmonary metastaseswere also observed in murines treated with activated、tumor antigen-pulsedmacrophages contrast to those treated with IL-2 gene-transfected macrophageswithout prior pulse of tumor antigen in vitro.

肿瘤抗原冲击的IL-2基因转染巨噬细胞治疗组小鼠期存活明显延长，肺转移结节明显减少，局部病理显示，肺肿瘤周围出现大量淋巴细胞浸润，我们推测这可能是因为抗原冲击的活化巨噬细胞除了增强对肿瘤细胞直接的杀伤效应外，还对其进行处理加工，将免疫信息传递给周围的淋巴细胞，从而引起其增殖活化，并浸润肿瘤组织中。

Nicorandil inhibits muscarinic activation of the ERK signaling pathway by reducing the intracellular Ca(2+) concentration.

尼可地尔通过减少细胞内钙离子浓度能阻断毒蕈碱细胞外信号调节激酶信号路径的激活。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
