It was observed that the influence of bud and its position on the healing process of grafting unions using hardwood sectioning method, and found that:(1) bud of a scion and its position to the graft unions have no influence on callusing formation of the isolation layers, and the early differentiation of cambia;(2) a scion bud closer to the grafting union would promote the formation of more compacted callus cells and the earlier formation of callus bridges;(3) conduit differentiation in grafting unions of lower-bud scions was later than that of other treatments.

利用滑动切片法对芽子有无及芽位对嫁接愈合过程的影响进行了观察，发现：(1)接芽有无及芽位对隔离层及愈伤组织形成和形成层的早期分化没有影响；(2)芽或去芽的芽位距接口近，可以促进愈伤组织的紧密连接，即愈伤组织桥的形成；(3)低位芽枝嫁接体中导管分化较晚，而其它处理导管的分化几乎是同时发生的，而且导管首先出现于愈伤组织薄壁细胞中。

We discovered that the mechanisms of borneol opening BBB involved (1) promoting the tight junction of endothelial cells opening:(2) increasing the quantity of pinocytosis vesicle in endothelial cells and enhance the pinocytosis;(3) inhibiting the activation of P-glycoprotein (P-glycoprotein is an efflux pump of drugs) and increase the permeability of BBB;(4) reducing the expression of intercellular adhesion molecule-1 in brain microvessel endothelial cells;(5) increasing the concentration of Ca〓 in brain microvessel endothelial cells;(6) increasing the activation of eNOS in brain microvessel endothelial cells.

随后，在对冰片开放血脑屏障的机制作进一步的研究时又发现，冰片开放血脑屏障的机制包括以下几个方面：(1)冰片可使血脑屏障内皮细胞间的紧密连接开放；(2)冰片能使内皮细胞内的囊泡数量增加，吞饮功能增强；(3)冰片能抑制P-糖蛋白的活性（P-糖蛋白是一种药物外排泵），而使血脑屏障的通透性增加；(4)冰片能使脑微血管内皮细胞ICAM-1表达量减少；(5)冰片使脑微血管内皮细胞内的Ca〓浓度升高；(6)冰片可升高脑微血管内皮细胞eNOS的活性。

Usually they exist as proenzyme, but after activation, they rapidly attack the blood brain barrier, degrade some matrix proteins of the basis membrane, break down the endothelial cell close connection protein, and promote the hydro-cephalus formation and phlogocyte infiltrating.

通常它们以酶原的形式存在，一旦活化，则迅速攻击血脑屏障，降解基底膜的一些基质蛋白，破坏内皮细胞的紧密连接蛋白，促进脑水肿的形成和炎细胞的浸润。

EN is mechanical to alvine mucous membrane the protective screen of machinery of mucous membrane of protective action bowel of protective screen is main by mucous membrane of the mucus layer of surface of alvine mucous membrane, bowel epithelial reach its the composition such as close connection.

肠内营养对肠屏障功能的维护机理是多方面的，EN制剂的种类对小肠功能的改善功能也不相同。1 EN对肠黏膜机械屏障的保护功能肠黏膜机械屏障主要由肠黏膜表面的黏液层、肠黏膜上皮细胞及其紧密连接等组成。

For example, blood urea concentration as an accurate measure of kidney function and the concept of extrarenal azotemia were first reported at that time.19 It was then believed that the kidney expended considerable energy to excrete urea into the urine and that moderate restriction of protein was beneficial to human patients as contended by Addis.20 This concept fell out of favor in human medicine when it was realized that renal work is tied closely to active sodium reabsorption and that urea is passively handled.

举例来说，血中尿素浓度依照肾脏功能的准确测量和肾外尿毒症的概念都是在当时第一次揭露。19而那时大家相信肾脏花费相当多能量以分泌尿素到尿液里，然而Addis主张适当限制蛋白质的摄取，是有益於患者。20这个观点赞同人类服用的药物上使用，当肾功能被积极钠紧密连接重新吸收，而尿素却是处於被动控制。

The Chinese authorities hope that shrinking journey times will both spread economic development more evenly and bind together potentially fissiparous regions.

中国当局希望用皱缩的旅途时间更进一步扩大经济发展的覆盖面，又将有分裂势力的边远地区紧密连接起来。

Actin plays an important role in the pathogenesis of nonbacterial chronic prostatitis.

β？actin作为紧密连接中的关键性调节因子，在慢性无菌性前列腺炎的发病过程中可能具有重要的调节作用。

As the critical regulatory factor of tight junction,βactin plays an important role in the pathogenesis of nonbacterial chronic prostatitis.

βactin作为紧密连接中的关键性调节因子，在慢性无菌性前列腺炎的发病过程中可能具有重要的调节作用。

The duodenal juice mainly consists of the bile acid, which is a sort of lipophilic steroid and may result in direct injuries of mucosal epithelial cells and their tight junctions. Some researches have showed that the bile acid directly damaged the chemical environment of mucosa surface and played a synergistical role in gastric mucosal lesions along with gastric acid and H.

十二指肠反流液中主要成分为胆汁酸，胆汁酸是十二指肠反流液中造成黏膜损伤的主要成分，为一种亲脂性类固醇，直接破坏黏膜上皮细胞以及细胞间的紧密连接，同时还对腔内及黏膜表面的化学环境造成直接的影响，增强胃酸、H。
