Results There were fetal type in 12 cases, embryonal type in 7 cases, anaplasia type in 3 and mixed type in 2. The cytoplasmic postive expression of CK, AFP, S-100 protein and Vimentin of epithelial tumor cells were found in 14, 10, 9 and 6 cases respectively. Positive staining of CEA, P53 and P16 of nuclei of epithelial tumor cells were found in 11, 9 and 7 cases respectively.Among the 12 cases who underwent surgical excision, 8 patients with fetal type survived over 5 years. Conclusions This study suggests that immunoreaction of hepatoblastomas are different in the histological subtypes.

结果 胎儿型12例，胚胎型7例，间变型3例和上皮间叶混合型2例；细胞角蛋白、甲胎蛋白、S-100蛋白和波形蛋白在肿瘤上皮细胞浆的表达分别为14例、10例、9例和6例，癌胚抗原、P53和P16蛋白在细胞核中的表达分别是11例、9例和7例；手术切除肿瘤12例中8例生存期超过5年者均为胎儿型。

At high power, the urothelial carcinoma does resemble urothelium, but the thickness is much greater than normal and the cells show more pleomorphism.

高倍镜下，移行细胞癌的细胞很象尿道上皮，但比正常尿道上皮厚，且呈多形性。

Results:Verrucous carcinoma was classified into three groups for clinical characteristics, ectogenesis group,kystis group and infiltrating group. The carcinoma epithelium cell grew exsertum like dilatate nail. Nest of squamous cell carcinoma could be found at the former of the cancer infiltration.

结果：口腔疣状癌按临床特征可分为外生型、囊肿型、浸润型，组织学上有膨大的上皮钉突呈&推进式&生长，部分病例浸润前缘有小团鳞状细胞癌灶。

Methods: Specimens of 46 cases of cervical cancer, 12 cases of normal cervical epithelia and 22 cases of cervical intraepithelial neoplasia were examined for E-cad expression by immunohistochemical staining.

应用SP免疫组化法观察12例正常宫颈上皮、46例宫颈鳞癌和22例宫颈上皮内瘤样病变组织中E-cad的表达。

We conclude that (1) S100A1 is a specific and sensitive immunohistochemical marker to differentiate nephrogenic adenoma from prostatic adenocarcinoma;(2) AMACR immunostaining does not seem to be a useful marker in distinguishing between these 2 lesions;(3) given that both S100A1 and AMACR have been reported to be expressed in renal tubular cells and in a subset of renal cell neoplasms, our findings confirm the histogenetic relationship between nephrogenic adenoma and renal tubular epithelium.

我们总结认为：（1）鉴别肾源性腺瘤和前列腺腺癌，S100A1既特异又敏感；（2）AMACR免疫染色鉴别这两种病变，效用不佳；（3）文献报道S100A1和AMACR均表达于肾小管上皮和部分肾细胞肿瘤，在此前提下，我们的结果证实了肾源性腺瘤和肾小管上皮之间的组织发生关系。

Barrett's esophagus, the most important risk factor in the deelopment of adenocarcinoma of the esophagus, is a metaplastic condition in which the normal squamous epithelium of the esophagus is replaced by columnar or glandular epithelium.

Barrett食管，是食管的正常的鳞状上皮被柱状或腺状上皮所取代的一种化生状态，为食管腺癌的发生中的最重要的危险因素。

From normal to hyperplastic epithelia, and to squmous carcinoma, the density of pisum sativum lectin receptors on cell and nuclear membrane tended to increase gradually.

发现从正常食管上皮、增生食管上皮到癌，细胞膜、核膜的豌豆凝集素受体呈递增趋势。

Expression of CD44V6 can be an early biological indicator of precarcinomatous epithelial cells. Gastric mucosa intestinal metaplasia can induce the expression of CD44V6, moreover, Hp infection can promote it.

CD44V6的表达可能是上皮细胞癌前病变出现的早期生物学信号，肠上皮化生细胞可能诱导CD44V6的表达，而Hp感染则有促进这种诱导表达的作用。

Results 17β-HSD type 2 was found in the cytoplasm of tumor cells in 5.3% of cases.In adjacent non-malignant tissues,82.9% of cases were positive and the enzyme was detected in the cytoplasm of epithelial cells of the acini and ducts.

结果：2型17β-HSD在乳腺癌细胞的细胞浆中有表达，阳性率为5.3%；在癌旁非恶性乳腺组织腺泡上皮细胞以及导管上皮细胞的细胞浆中表达，阳性率为82.9%。

There were clinical and histological similarities among verrucous hyperplasia, verrucous carcinoma and squamous cell carcinoma of the oral cavity, especially, in those cases with borderline morphology.

口腔之疣状上皮增生、疣状癌及鳞状细胞癌在临床及组织学上的变化相当类似，特别是那些组织形态呈现边缘型者。
