Results: A 24-year-old woman suffered from acute painful sensation of both eyes after putting on contact lenses soaked in hydrogen peroxide care solution. Bilateral punctate corneal epithelial erosions were diagnosed. To relieve pain, she, by herself, applied topical 0.5% proparacaine eye drops to both eyes with increasing frequency to almost hourly. However, the pain was aggravated. On examination 2 days later, a large central disciform epithelial defect and diffuse edema of the residual epithelium were noted in both corneas. With the treatment using non-preserved artificial tears, the epithelial defects started to heal the next day and ring-shaped stromal cellular infiltrates were observed at the border of previous epithelial defects.

病例报告结果：一位24岁年轻女性因为配戴曾浸泡於含双氧保养液之隐形眼镜，造成双眼角膜点状上皮缺损，为了减少疼痛几乎每一小时双眼使用0.5%丙美卡因局部麻醉眼药水，然而疼痛恶化，并且在两天之后产生双眼角膜中央盘状上皮缺损，在使用不含防腐剂之人工泪液药水后，第二天表皮开始逐渐愈合，可以发现在原本上皮缺损边缘出现环状基质细胞浸润。

Results: CK18 was not detected in normal and abnormal oral tissue sections. But in normal nonkeratinized mucosa, CK19 was detected in the basal cell layer dispersively. In epithelial dysplasia, CK19 was detected in the suprabasal cell layer and the number of CK19-positive cell layers was correlated with the dysplasia degree of epithelia. Furthermore, CK19 was detected in oral squamous cell carcinoma, especially in the poor-differentiated cancer cells.

结果：正常和异常的口腔粘膜均未检测到CK18；CK19可表达于正常非角化上皮的基底层细胞、异常增生上皮的基底上层细胞及口腔鳞状细胞癌中，阳性细胞数与上皮的异常增生程度及鳞癌的分化程度相关。

Mirror infiltrating the cancer vagina the image is that the blood vessel is abnormal mainly,original place cancer vagina mirror visible image acetic acid white epithellum,major partners the shape blood vessei,heterotype blood vessel,mosaic and floccosoids wait a little bit;CIN acetic acid white maximum appears on epithelium,the shape blood vessel,heterotype blood vessel,rnosaic and floccosoids take second place;The chronic cervicitis gives first place to no representative shape blood vessel China and acetic acid white epithelium.

浸润癌阴道镜图像主要是血管异常，原位癌阴道镜图像可见醋酸白色上皮，多数伴有点状血管、异型血管、镶嵌和白斑等；CIN醋酸白色上皮出现最多，点状血管、异型血管、镶嵌和白斑次之；慢性宫颈炎以不典型点状血管和醋酸白色上皮为主。

These cancer cells might histogenetically be related to the transitional or metaplastic epithelium of prostate according to morphological analysis,(2) Mucinous adenocarcinoma, Xanthomatous carcinoma, ductal carcinoma, medullary carcinoma, endometrioid carcinoma, papillary carcinoma and signet-ring cell carcinoma were positive for PSA and 35βH11, these carcinomas might histogenetically be related to prostatic secretory epithelium,(3) Prostatic carcinoid showed positive to PSA, 35βH11, NSE and CgA, corresponded with endocrine cell originator,(4) Small cell carcinoma were negative for PSA, 35βH11, NSE and CgA, whether or not it originates from endocrine cells, storage cells or basal cell of prostate had yet to be proved,(5) 34βE12 marking was negative in cancerous areas of 27 cases, and the basal cells were absent in PPTC.

从形态分析，这两种癌可能同源于移行上皮或化生上皮：（2）粘液腺癌、黄色瘤样癌、导管癌、髓样癌、宫内膜样癌、乳头状癌及印戒细胞癌均显PSA及35βH11阳性，提示这几种癌可能来源于分泌上皮，（3）类癌对PSA、35βH11、NSE及CgA均显阳性，符合内分泌细胞来源，（4）小细胞癌无PSA、NSE及CgA表达，对c-erbB-2及35βH11显阳性，是否来源于前列腺内分泌细胞、储备细胞或基细胞有待证实，（5）27例癌区均无34βE12表达，提示PPTC中基细胞缺失。

The expression of CD44 was strong positive in stratum intermedium at the bell of differetiational stage, bell of secretory stage, and bell of maturative stage of mouse tooth germ.

在钟状期CD44在口腔上皮、牙板上皮强阳性表达；外釉上皮、星网状层、成牙本质细胞弱阳性表达；分泌期的成釉细胞和牙囊阳性表达。

The cells are found in between epithelial cells, at the bottom of epithelial cell, between glandular epithelial cells, a few in the epithelium basal portion and membrana propria.

嗜银细胞多分布与消化道粘膜上皮细胞之间或腺泡上皮之间，有时可见于上皮基部和固有膜内。

There was no difference among the three groups.At the 4th week,corneal epithelial cell covering the laser section in both groups was much neoformative collagen arranging irregularly and cicatricial tissue in the anterior stromal layer.

术后一周，在光学显微镜下，三组角膜上皮细胞均已完全覆盖激光切削面，新生的角膜上皮细胞层数多，基底层上皮细胞大小不一。

Results: The Schwann cells promoted the survival and differentiation of neuroepithelial stem cells, and the number of the neurons decreased with an increase of serum concentration. Both the neuroepithelial stem cells and serum promoted the survival and the proliferation of the Schwann cells.

结果：Schwann细胞促进神经上皮干细胞存活和分化，随着血清浓度增加，神经上皮干细胞分化形成的神经元比例减少；神经上皮干细胞及血清均促进Schwann细胞存活和增殖，随血清浓度增加，存活及增殖率增加。

Results Both the area density of stroma and the ratios of stroma to epithelium were the highest in the periurethral zone and the lowest in the supcapsular zone. While the area density of epithelium and glandular lumen in the periurethral zone was significantly lower than those of peripheral zones.The ratios of glandular lumen to epithelium among three zones were not statistically different.

结果 间质面积百分比和间质/上皮比值在尿道周围区、中间区和包膜下区中均依次递减( P ＜0.01)，而上皮和腺腔面积百分比则依次递增( P ＜0.01)；三区间腺腔/上皮比值差异无显著性。
