Small intestinal biopsies showed subepithelial collagen deposition with varying degrees of villous atrophy and varying numbers of intraepithelial lymphocytes. Four patients had previous biopsies showing enteropathic changes without collagen deposition. Seven cases were associated with collagenous colitis and 1 also had features of lymphocytic colitis. Three patients also had collagen deposition in gastric biopsies. One case was associated with lymphocytic gastritis. Celiac disease (CD, gluten-sensitive enteropathy) was documented in 4 patients. Five patients made a clinical improvement with combinations of a gluten-free diet and immunosuppressive therapy. Two patients died of complications of malnutrition and 1 of another illness. Clonal T-cell populations were identified in 5 of 6 cases tested. Four of these patients improved clinically after treatment but 1 has died. Collagenous sprue evolved on a background of CD in 4 cases. There was no history of CD in others and these cases may be the result of a biologic insult other than gluten sensitivity.

小肠活检表现为上皮下胶原沉积，绒毛萎缩程度不一，上皮内淋巴细胞浸润数量不等。4例患者以往曾做过活检，表现为其他肠病改变，并没有胶原沉积。7例患者合并胶原性结肠炎，且1例还有淋巴细胞性结肠炎的特征。3例患者胃活检也发现有胶原沉积。1例患者合并淋巴细胞性胃炎。4例患者有乳糜泻（CD，谷蛋白敏感性肠病）病史。5例患者经无麸质饮食和免疫抑制治疗后，临床症状有所改善。2例患者因营养不良合并另一种疾病而死亡。6例患者做了T细胞受体基因重排，其中5例发现有克隆性T细胞群，这5例中有4例治疗后临床症状加重，且1例死亡。4例患者在CD的基础上病发胶原性口炎性腹泻；其余患者无CD病史，他们的发病也许是生物源性损害，而非谷蛋白敏感。

Clinical manifestations are soreness on epigastric region, decreased appetite, distention after meal and eructation. It belongs to "epigastric pain" and "Stomach Pi syndrome" in TCM with characteristics of repetition and pertinacity. In 1978, WHO listed chronic atrophic gastritis as precancerous lesions of gastric cancer because its complications of intestinal metaplasia and dysplasia are closely related to gastric cancer. This has been a research focus in clinical practice and pathology for years.

临床主要表现为上腹隐痛、食欲减退、食后饱胀、嗳气等，属中医学"胃脘痛"、"胃痞"等范畴，具有反覆发作、迁延难愈的特性。1978年WHO将慢性萎缩性胃炎列为胃癌的癌前状态，而在其基础上伴发的肠上皮化生(Intestinal metaplasia，IM)和域异型增生(DYSplasia， DYS)，则与胃癌的发生关系密切，被视为癌前病变(Precacerous lesions Of gastric cancer， PLGC)多年来始终是临床及病理学研究的重点。

On polarized epithelia, Hp is able to grow directly on the apical cell surface in conditions that do not support the growth of free-swimming bacteria.

在极化的上皮上，在不支持自由游走细菌生长的情况下，Hp可以在顶端细胞上直接生长。

Any of the minute hairlike structures projecting from the surface of certain types of ''.

微绒毛；微小突起物；指状突起一些上皮细胞表面上突起的微小发状结构的总称，尤指小肠上的

From days 4 to 5, COX-1 immunostaining reached to a high level in the luminal epithelium.

在早期妊娠第6天，在子宫腔上皮上能检测到较高水平的COX-1免疫染色，在腔上皮下基质能检测到较低水平COX-1免疫染色。

Hastily brushing the thistles from its coat, he laid the leather saddle on its back, pulled the bridle over its mangy ears and heaved himself up.

他匆匆地刷了刷马身上的蓟，放上皮马鞍，往长藓的马耳朵上套上笼头，跨上了马背。

The results indicate that the thyroid gland of grey mullet is dispersedly distributed in the region of the arteria branchialis afferens of the first to the third pair of branchial arches. The monolayer follicle epithelial cells around a follicle were squamous shaped or cuboidal shaped, indicating an asynchrony of cellular activity in a follicle. The scale of the two shapes of cells differed significantly among developmental stages.

结果表明，鲻鱼甲状腺滤泡分散地分布在第1对至第3对鳃弓的入鳃动脉之间；构成同一滤泡的单层上皮细胞呈扁平形和立方形两种形态，反映出同一滤泡中上皮细胞生理活动的不同步，且发现不同发育时期的鲻鱼这两种形态细胞的比例有显著差异。

Methods: Prepare and identification of AFE. To detect the effects of AFE on trans-epithelium electric resistance, Tight Junction proteins occludin and ZO-1, cell wound closure ability in vitro and the production of Muc5ac and GM-CSF by human bronchi epitheliums (16HBE-14o).

制备并鉴定烟曲霉菌提取物，观察AFE体外培养人支气管上皮细胞(16HBE-14o)的跨上皮细胞电阻、紧密连接结构蛋白occludin和ZO-1、细胞体外修复功能、细胞合成分泌Muc5ac和GM-CSF的作用。

Only 3 cases partially necrosed at distal partion, the other survived completely. Conclusion Applying retrograde fasciocutaneous flap with a pedicle of superagenual cutaneous artery to repair scar contracture of popliteal fossa is a good operation method with the advantages of good results of primary repair of both the supplied region and the accepted region.

隐动脉膝上皮支筋膜皮瓣修复腘窝部瘢痕挛缩，取得了修复区和供皮区一期修复的良好效果，并保证了术后修复区的良好功能，是一种比较理想的手术方法。

AIM: To analyze the apoptosis and proliferation of HERS (Hertwig's epithelial root sheath) and to evaluate the roles of HERS cells in the development of cementum.

目的：观察牙根发育中上皮根鞘细胞(Hertwig's epithelial root sheath， HERS)断裂后结局和增殖凋亡相关基因的表达，探讨上皮根鞘在牙根发育特别是牙骨质形成中的可能作用。
