变型的

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。

The genetic distance a mong different splash types of H.axyridis was 0.0021 to 0.0328 The aver age gene tic distance was 0.0193 The molecular phylogenetic tree suggested that the me mb ers with the same elytron color were grouped together with high bootstrap confid ence values, showing low diversity among the populations. H. axyridis ab. luna t a Hem and H.axyridis var. spectabilis Fald were most closely related. H.ax yridis var. axyridis Pallas was a primordial population of coccinellidae, which wa s differentiated earlier than the other populations.
