PFOS induced thyroid follicle cell hyperplasia, the depletion of colloid and even vacuolation with dose-effect relationships after 6 months exposure. Malformations of gonad with intersex, pearling and segmental aplasia were found in all treatment groups. The gonad with intersex showed a testis tissue with a female ovarian cavity like structure.

6个月后，PFOS组甲状腺出现滤泡上皮细胞增生、胶质减少甚至空泡化等现象，且随着PFOS浓度的增加而加重；各组幼蛙性腺出现间性、睾丸珍珠状和先天性萎缩等畸形现象，外观为间性的性腺主要表现为睾丸组织中产生类似雌性个体的卵巢腔。

Results With the expression in normal salivary gland as a standard, low C-erbB-2 mRNA expression was seen in adenolymphoma, basal cell adenoma. However, various degrees of over-expression of C-erbB-2 oncogene mRNA were detected in pleomorphic adenoma, mucoepidermoid carcinoma,acinic cell carcinoma ,adenoid cystic carcinoma ,papillary cystic carcinoma,and myoethelial cell carcinoma.

结果 正常涎腺和涎腺肿瘤中发现不同程度C-erbB-2mRNA的表达，以正常涎腺组织的表达水平为基准，在腺淋巴瘤、基底细胞腺瘤呈现低表达、无表达或与正常涎腺组织表达水平相似，多形性腺瘤、粘液表皮样癌、腺泡细胞癌、腺样囊性癌、乳头状囊腺癌和肌上皮癌则呈现不同程度的过表达。

Results MMP-2 positive cells are localized in peripheral columnar while no positive cells are seen in odontogenic karatocysts and dentigerous cysts.

结果 成釉细胞瘤中MMP-2阳性染色位于肿瘤外周柱状细胞的胞浆中，中心星网状细胞未见表达；角化囊肿和含牙囊肿的上皮细胞中均未见MMP-2的阳性表达。

TCT smear screening is necessary and safety for routine prenatal tests ,there is no difference in the cervical squamous interepithelial lesions between pregnant and non- pregnant women.

Results The endometrium by squeezing was in the shape of cylinde r with integrated tissue structure including endometrial epithelium,gland and capillary. Moreover the endometrium situated in the mesometrium was incomplete.

结果 挤压法得到的小鼠子宫内膜呈圆形条状；子宫内膜组织结构完整，具有内膜上皮并包含腺体、血管的基质；意外发现子宫系膜侧的子宫内膜缺损。

in 2003 the who mammary gland tumor new classification increased one new type - wetting quality micro papilliform tumor under the mammary gland epidermis tumor item (invasive micropapillary carcinoma, impc). impc is breast cancer's one rare type, occupies breast cancer 3%~6%.

2003年who乳腺肿瘤新分类在乳腺上皮性肿瘤项下增加了一种新的类型-浸润性微乳头状癌（invasive micropapillary carcinoma，impc）。impc是乳腺癌的一种少见类型，占乳腺癌的3%~6%。

GT is rich in renal proximal tubules especially in the proximal convolutes tubules.Urinary γ-GT may be as a index of renal damage.

肾脏近端肾小管的上皮细胞内，尤其刷状缘中富含γ-GT，尿中γ-GT 来自肾脏，可能作为肾脏损害的一种指标。

Methods:In addition to the Schirmer Test for Tear Break-Up Time,Rose Bengal Staining and Fluorescein Staining were used.We tested the tear film mucous layer by CIC for a control group and for dry eye patients.

对45人90眼正常组和80人160眼实验组除采用泪液分泌实验I、泪膜破裂时间、虎红染色及荧光素染色计分等常用眼表泪功能检查外，重点采用CIC，通过观察结膜上皮细胞情况及杯状细胞数来了解正常眼、干眼的泪膜粘液层的情况。

Results Among16826 subject cases,1 case of squamous cell caroinoma has been found,2cases of CIN-3,12cases of CIN-2,and391 cases of CIN-1 have been found And among the found cases,there are263 caese of CIN-1 case of HPV infection;197cases of trichomonal infection;388cases of candidal infection,156 cases of bacterial infection .14410cases of inflammatory cell changing;2001 cases of ceriical intraepithelial neoplasia,8cases of ASC-US and1 case of AGUS.

结果 16826例标本中，发现1例鳞状细胞癌；2例CIN-3；12例CIN-2；391例CIN-1，其中263例 CIN-1HPV感染；滴虫感染197例；霉菌感染388例；细菌感染156例；有炎性反应性细胞改变的14410例；无上皮内病变或恶性瘤变的2001例；8例ASC-US；1例AGUS。

Sept. 11, 2003 Core needle biopsy helps differentiate phyllodes tumor from fibroadenoma, according to the results of a query of a radiology database published in the September issue of the Archives of Surgery . The authors suggest that this technique can signficantly reduce the need for surgery of fibroepithelial lesions.

Sept。 11， 2003-根据一篇发表於9月号Archives of Surgery的研究结果显示，粗针切片检查有助於自纤维性瘤区分出叶状瘤，作者建议，这种技术也可以明显地减少进行纤维上皮之病灶手术的需要。
