实验研究表明，通过调整POSS和表面活性剂的物质的量比例可以改变片层结构，发现当POSS成分大大过量的时候，片层重复单元按照&烷基-POSS-POSS-烷基&顺序排列，对应较大的层间距；当表面活性剂成分大大过量的时候，片层重复单元按照&烷基-POSS&顺序排列，对应较小的层间距。

By comparing the electrodeposition rate and the particlesize of nanometer Ag film prepared by methyl sulfonic acid silver system with those of nanometer Ag film prepared by nitrate silver system under the same conditions, it is found that the particlesize of nanometer Ag film electrodeposited with nitrate silver is smaller and the growth rate of the nitrate silver nanometer film is faster. During the experiment, the silver grain was smaller and the distribution was more uniform in the nitrate silver electrolyte than in the methylsulfic silver electrolyte.

Crohn's disease was induced by trinitrobenzene sulfonic acid in the model group. The mice were sacrificed 5 days afterwards and LPMC were isolated and cultured. The expression of CCR2 and CCR5 on LPMC were determined by flow cytometry. The secretion of MIP-1α in the supernatant was determined by enzyme-linked immunosorbent assay, and the expression of MIP-1α mRNA was determined by reverse transcriptase polymerase chain reaction.

模型组小鼠以三硝基苯磺酸灌肠造模。5d后处死，提取和培养LPMC，采用流式细胞仪测定小鼠LPMC中趋化因子受体CCR2、CCR5的表达；采用酶联免疫吸附测定检测培养上清液中MIP-1α的分泌；采用逆转录聚合酶链反应检测MIP-1α mRNA的表达。

AIM: To investigate the role of mucosal addressin cell adhesion molecule-1 (MAdCAM-1) in the pathogenesis of trinitrobenzene sulfonic acid induced rat colitis and to investigate the mechanisms underlying the anti-inflammatory action of Qingchang Supporistory.

目的： 探讨黏膜地址素细胞黏附分子-1(MAdCAM-1)在三硝基苯磺酸诱导大鼠结肠炎发病过程中的作用；研究清肠栓是否通过抑制MAdCAM-1在结肠黏膜的表达，而发挥其抗炎愈疡作用。

Results: Normal mature IEC expressed low TRAIL levels, whereas, in inflammatory lesions, TRAIL messenger RNA and protein were markedly up-regulated in IEC and lamina propria lymphocytes at levels comparable with trinitrobenzene sulfonic acid-induced colitis.

结果：正常成熟IEC表达低水平的 TRAIL ，而炎性病灶IEC及薄固有层淋巴细胞中的TRAIL信使RNA和蛋白显著上调，其水平可与由三硝基苯磺酸诱导的结肠炎相近。

Methods: The chemical model was induced by trinitrobenzene sulfonic acid and the mechanical model was induced by colon irritation during postnatal development.

化学造模采用TNBS模型，物理模型采用新生鼠发育期肠激惹方式诱导模型。

The results of this reseach showed that administration of SF intracolonically had protective effect on the colon injury in the rat model of colitis induced by acetic acid enema, which was probably due to the mechanism of antioxidation, inhibition ofarachidonic acid metabolis and platelets activation, administration of SF intracolonically also showed protective effect on the colon injury in the rat model of colitis induced by trinitrobenzene sulfonic acid and ethanol, which was probably due to antioxidation and inhibition of macrophages activation.

实验研究表明，大鼠分别经乙酸、TNBS和乙醇处理后均出现典型的结肠炎症状，给药后分别评价结肠粘膜损伤指标、结肠组织病理变化，检测结肠组织炎症指标、结肠组织氧化损伤指标及主要炎性细胞因子改变；实验结果：阿魏酸钠对大鼠乙酸性结肠炎结肠粘膜损伤具有缓解保护作用，其机制可能与直接抑制炎症结肠粘膜花生四烯酸代谢过度，抑制血小板活化，清除大量氧自由基有关；阿魏酸钠对大鼠TNBS性结肠炎粘膜免疫损伤亦具有缓解保护作用，其机制可能与抗氧化，抑制结肠巨噬细胞活化有关。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
