Results:17 rats were confirmed successful transplantation by MRI,the capacity of the tumor was 88.40±7.62mm3 on 8th day, 986.80±114.46mm3 on 16th day,the volume growth was 8-12 folds;on 8th day following transplantation,the tumor tissue was gray in color with fish homogen state without interior necrosis, the tumor cells were nest-distributed by HE staining,large dense staining of nucleus with manifest heteromorphism,tumor microvessel count increased by immunohistochemistry with buffy yellow staining, VEGF high expressed in the tumor cells with buffy yellow granule shape.

结果：17只大鼠经MRI检查证实均种植成功，肿瘤体积第8天为88.40±7.62mm3，第16天为986.80±114.46mm3，体积增长8-12倍之间；种植第8天，肿瘤组织呈灰白色、鱼肉均质状，内部未见坏死，HE染色肿瘤细胞呈巢状分布，胞核大浓染，异型性明显；免疫组织化学示肿瘤微血管数目较多，呈棕黄色染色，肿瘤细胞VEGF高表达，呈棕黄色细颗粒状。

Cases of tumor was performed by immunohistrochemical staining EMA and Vim were positive. 12 cases were hyperplasic lesions of mesothelial cell. Induced rats' MPM had a higher similarity with human' s MPM, especially in pathogenicity, positions, histological type and biological behavior of invasion and metastesis.

结果 实验组发生胸膜间皮瘤66例，诱发率71.74%，大体形态肉眼结节型间皮瘤较多见（72.73%）组织形态可见上皮型、梭形细胞型及混合型双向多潜能分化，13例免疫组化EMA及Vim双向阳性，并可见12例胸膜间皮细胞增生性病变，诱发瘤在病因，发病部位，组织形态学以及浸润转移的生物学行为方面与人体间皮瘤极为相似。

结果 260例肝穿活检组织病例中，急性肝炎20例；慢性肝炎78例；肝硬化39例；原发性肝细胞癌28例；肝细胞核异质27例；肝转移性腺癌20例；脂肪肝12例；乙醇肝5例；肝囊肿3例；先天性胆管闭锁2例；穿刺组织结构模糊6例；未穿到或仅穿到少量肝细胞20例。

There were 8 patients in the macromastia group and 5 patients in the control group. The result didn't show significant difference between the two groups. There is no difference between the two groups in mammary epithelial cell size measurement and Akt-1/2/3 immunohistochemistry stain. The levels of Ki-67, phospho-Akt-1/2/3, and STAT5a of juvenile macromastic patients are higher than those of the patients of the control group, and the results are statistically significant.
