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。

Results VEGF and PLGF were mainly expressed in trophoblast, next in decidua and endothelial cells, and also in stroma.

结果 各组孕妇胎盘组织中的VEGF和PLGF主要分布于滋养叶细胞，其次是蜕膜组织，绒毛血管内皮细胞和部分间质细胞也有表达。

Methods:33 cases were classified asⅠ,Ⅱ,Ⅲ according to heteromorphic degree of interstitial cells,nuclear fission and special interstitial ingredient.

对 33 例经病理证实的乳腺叶状囊肉瘤，根据间质细胞异形程度和核分裂数、是否浸润、是否含有特殊间质成分进行分级。

Methods The clinical and histopathologic symptoms of two patients with sarcomatoid carcinoma of the bladder were macrohematuria and vesical irritability. Cystoscopy showed the carcinoma was solid tumor with necrotic tissue on the surface. Sarcomatoid carcinoma was mainly composed of transitional epithelial cancer cells and malignant mesenchymal cells (spindle cells and polymorphic cells), with a transitional region of interlacement of these cells. Immunohistochemical testing showed the cells were positive for cytokeratin, c arcinoembryonic antigen and smooth muscle actin.

分析2例膀胱肉瘤样癌患者的临床资料并结合文献进行讨论。2例患者均有肉眼血尿或伴有膀胱刺激症，膀胱镜检查为实体瘤，表面有坏死组织；病理表现，肿瘤主要由移行上皮癌细胞和恶性间叶细胞组成，之间可见移行过渡；免疫组化CK、CEA、SMA。

This protein prolonged FGF8 expression in AER and expanded Sox9 expression in mesenchyme.

Ihh蛋白延长了AER中FGF8的表达，扩展了间叶细胞中Sox9的表达区域。

One eye in patients was selected to do the tear film breakup time, Schirmer test and cornea fluorescein staining, and the expression of NFκB and TGFβ1 on bulbar conjunctiva endepidermis was detected by immunohistochemistry.

TGFβ1是多功能细胞因子，对上皮细胞具有较明显的抑制作用，对成纤维细胞及其他间叶组织来源的细胞均具有明显的刺激作用，表现为胶原合成增加，有利于组织修复及伤口愈合［3，4］。

A total of 150 mesenchymal neoplasms of the GI tract, abdominal cavity, and retroperitoneum were retrieved from consult and surgical pathology archives, including 54 GISTs (8 KIT-negative; 13 desmin-positive), 17 GI leiomyosarcomas, 11 GI mural leiomyomas, 13 leiomyomas of the muscularis mucosae, 12 gastric schwannomas, 15 inflammatory myofibroblastic tumors, 9 cases of mesenteric desmoid fibromatosis, 10 dedifferentiated liposarcomas, and 9 malignant peripheral nerve sheath tumors.

我们从会诊病例及活检病例中找出150例间叶性肿瘤（来自胃肠道、腹腔和后腹膜），其中包括54例GISTs（8例KIT阴性、13例desmin阳性）、17例GI道平滑肌肉瘤、11例GI道肌壁间平滑肌瘤、13例GI道粘膜肌层平滑肌瘤、12例胃的神经鞘瘤、15例炎性肌纤维母细胞瘤、9例肠系膜韧带样纤维瘤、10例去分化型脂肪肉瘤和9例恶性外周神经鞘膜瘤。

The characters in Impatiens, such as shape and lenghth of stomata, T-thickening at the polar region of guard cells and ornamemtation of leaf epidermis are more important between species and can be used one of the taxonomically important characters of Impatiens.

叶表面纹饰，气孔的形状、大小及气孔保卫细胞两极&T&型加厚等特征在种间具有一定的差异，可作为该属植物分类的重要特征之一文中还探讨了叶表皮微形态学特征在凤仙花属分类中的意义及有关紫花黄金凤的分类学地位间题。

For tumors which have been well sampled and exhibit (1) a microcystic pattern and regions with lobulated cellular masses with intervening, sometimes hyalinized fibrous stroma,(2) an absence of morphologic features enabling any other specific diagnosis in the sex cord-stromal category,(3) an absence of epithelial elements, and (4) an absence of teratomatous or other germ cell elements, we propose the designation microcystic stromal tumor.

我们很好地抽样调查了4例肿瘤，显示：（1）微囊样式和有时插入玻璃样变的纤维间质中的分叶状细胞团区，（2）能造成在性索间质这个大类中其他具体诊断的形态特征缺失，（3）上皮成分缺失，（4）畸胎或其他胚芽细胞成分缺失，我们提议定其名为微囊性间质瘤。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
