The organic cells that have potential excitation can change the penetrability of Na~+ if they receive stimulation from external ,then Action potential occurs.

对组织细胞进行刺激可以改变可兴奋细胞对Na~+或Ca~(2+通透性，从而产生动作电位，使其内部的Na~+、K~+离子通道发生变化引起内部环境的改变，最终改变细胞的状态。

Bronchial asthma is the most common chronic diseases in children.Asthma can not be fully explained by imbalance of Thl/Th2.With the research progress of CD4+ CD25+ Treg cell,it has been found that CD4+ CD25+ Treg cell related factors such as forkhead/winged helix transcription factor,heine oxygenase-1,transforming growth factor-β,cytotoxic T lymphocyte-associated antigen-4 are closely linked to asthmatic mechanisms.

支气管哮喘是一种儿童时期最常见的慢性疾病，单纯的Thl/Th2应答失衡并不能完全解释支气管哮喘的发生，伴随着CD4+CD25+调节性T细胞的研究进展，人们发现与CD4+CD25+Treg细胞相关的因素如叉头/翼状螺旋转录因子、血红蛋白加氧酶-1、转化生长因子β、细胞毒性T淋巴细胞相关抗原-4与支气管哮喘均有密切的联系。

MSCs did not proliferate within the alginate-GRGDY matrix during the 2 weeks examined. These results were further substantiated by concurrent cell density measurements using a hemocytometer.

在2周的检查期内，间充质细胞干细胞在甘氨酸－精氨酸－甘氨酸－天冬氨酸－酪氨酸藻酸盐环境中并没有发生增殖，这些结果在用血细胞计数器测量细胞密度时得到进一步确认。

Objective To determine the expression of CD44 in the liver tissue.Method 26 cases of liver cancer,16 cases of hepatocirrhosis and 5 cases of normal liver tissue were studied by HE stain and immunohistochemistry.

CD44是一种粘附分子，能介导细胞与细胞以及细胞与基质间的粘附，近年来的研究发现它与人体肿瘤的发生、发展及转移有着密切的关系，对肿瘤病人的预后判断具有重要的意义。

Results: The pulmonary artery wall of RHD group become more incrassate than that of the control group.

结果：RHD患者肺动脉的结构发生明显改建，RHD及对照组肺动脉内都有增殖与凋亡的细胞，但RHD组增殖细胞多而凋亡细胞明显减少。bcb2在RHD组中表达强度明显高于对照组，而bax在对照组中的表达高于RHD组。

Objective To investigate the alteration of vascular endothelial cells and circulation endothelial cells damage in acute-phase Patients with Coronary Heart DiseasConstruct technology platform of vascular endothelial cells damage, in order to provide new theory evidence and laboratory indicatrix of earlier-phase prophylaxis and diagnosis for nosogenesis、development、turnover of Coronary Heart Disease Methods 65 acute-phase Patients with Coronary Heart Disease of preparing for operation of heart...

目的探讨冠心病患者急性期血管内皮细胞、循环内皮细胞损伤的特点，构建检测内皮细胞损伤的技术平台，为冠心病的发生、发展、转归，甚至早期预防及诊断提供新的理论依据和实验室指标。

In resting cysts, the microtubules under the pellicle, cortical ciliatures, conjunctions between cilia basal bodies, supporting structure of basal bodies and other microtubule structures are absorbed in different extent; microtubule-like assemble bodies appear at the center of the remained cilia basal bodies; the granules of chromatin and nucleolus in macronucleus become smaller whereas nucleus pores of the micronucleus become bigger; the inner membrane of some nucleus pores are attached with chromatin.

结果表明：纤毛虫形成包囊过程中，皮层细胞质中产生具有自噬泡消化特征的细胞器，将部分纤毛结构等逐步消化；休眠包囊中，表膜下微管、皮层纤毛器和纤毛基体间连接、基体托架及其他微管结构不同程度地被吸收、在残剩纤毛基体的中央形成微管形结构聚合体，大核染色质和核仁颗粒变小，核孔增大，并发生染色质附着于核孔内膜的现象；细胞脱包囊期间，皮层细胞骨架、线粒体等经历了在残剩结构基础上的再分化。

The development of anther and ovule followed the finish of the flower organ initiation. Pollen mother cells and well developed microsporagium wall occurred when the diameter of the bud reached about 3.0 mm, and the archesporial cell which played the role of megaspore mother cell formed in ovule when the diameter of the bud reached about 3.5 mm.

花药及胚珠的发育与花器官的形态发生之间有明显的连续性，当花蕾直径为3.0 mm左右时花粉母细胞及完整的花粉囊壁形成，直径达到3.5 mm左右时胚珠中出现孢原细胞的分化，它直接起大孢子母细胞的功能。

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。

Giant cell tumor of bone is a kind of common bone tumor,which has characteristics of high recurrence rate and invasion.recently,tumor vessel angiogenesis has been the warm spot of research.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.the correlated research has very important significance for judging gct prognosis and guiding therapy.

骨巨细胞瘤（giant cell tumor of bone，gct）是一种常见骨肿瘤，由于其高复发率和强侵袭性，备受临床骨科工作者的关注。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。骨巨细胞瘤生物大分子研究的不断深化对判断gct的预后及指导治疗有重要意义。
