Results Among the 52 cases, 30 cases were confirmed to fibrosarcomas, which were identical with primary dingnoses;22 cases were revised to malignant fibrous histocytoma (8 cases), malignant nerve sheath tumor (4 cases), monophasic spindle cell synovial sarcoma (3 cases), leiomyosarcoma(3 cases), rhabdomyosarcoma(2 cases) and abdominal desmmoid tumor (2 cases). Of the 18 cases, only two cases were misdiagnosed and were revised to malignant fibrous histocytoma and spindle cell synovial sarcoma, respectively.

PPO基因在多发性骨髓瘤、恶性纤维组织细胞瘤、恶性淋巴瘤、恶性神经肉瘤、孤立性浆细胞肉瘤、原始神经外胚瘤、脂肪瘤、骨及软骨肉瘤等肿瘤中没有表达。在骨巨细胞瘤中有微弱表达。

The protein had the same antigenicity as IgG, and the change of the protein had the same tendency as SHP-2, which was higher in canceration groups than in uncanceration groups and control groups in thymus cells, but there weren't significant change in bone marrow cells;⑧ The change law of the expression of SHP-1 and SHP-2 during γ-ray induced malignant transformation in BEAS-2B cell is that the expression of SHP-1 was increased synchronistically with malignant transformation of cell, and the expression of SHP-2 didn't have significant correlation with malignant transformation of cell.

癌变组胸腺细胞中SHP-2 mRNA编码PTPase催化区的700～1096bp间可能出现甲基化；⑦癌变组的胸腺细胞中存在一相对分子质量约为55×10〓的蛋白质，它与IgG具有相同的抗原性，其表达量的变化趋势与SHP-2的蛋白表达变化趋势基本一致，即在胸腺细胞中明显高于对照组及未癌变组，但在骨髓细胞中对照组高于癌变组；⑧SHP-1、SHP-2在γ射线诱发的BEAS-2B细胞恶性转化过程的变化规律：SHP-1蛋白表达量的升高与细胞的恶性转化在时间上基本一致，而SHP-2蛋白表达量与恶性转化无明显关系。

ABSTRACT Objective To discuss the clinical pathologic features and differential diagnosis of mixed germ cell sex cord stromal tumorwith malignant variant of germ cell tumor Methods The clinical pathologic datum and immunophenotype were studied in the case of ovary MGCSCST with malignant variance of germ cell tumor Results The patient's genital anatomy and female phenotype were normal,karotypes was 46xx with uterogestation The tumor tissue consisted of mixed germ cells and sex cord stromal cells with evident malignancy of mixed germ cells There was no atypical structure of gonadoblastoma in tumor tissue Conclusion MGCSCSST has complex morphosis,thus,to prevent misdiagnosis,more samples should be collected and more slices be cut The patient may have prognosis malo when there are high malignant variants of mixed germ cells in tumor tissue

目的 探讨混合性生殖细胞性索间质肿瘤(mixed germ cell sex cord stromal tumor，MGCSCST)伴恶性生殖细胞肿瘤变异型的临床病理特点及鉴别诊断。方法卵巢MGCSCST伴恶性生殖细胞肿瘤变异型的病例进行临床病理特征和免疫表型分析。结果患者生殖器的解剖结构和女性表型正常，染色体组型是46xx，足月妊娠。肿瘤组织由混合性生殖细胞和性索间质肿瘤构成，混合性生殖细胞有显著的恶性特征。瘤组织中没有典型的性腺母细胞瘤结构。结论 MGCSCST有复杂的形态结构，因此更多的取材和切片可以防止误诊，当肿瘤组织中的混合性生殖细胞有高度恶性变异时，患者预后不良。卵巢肿瘤；生殖细胞性索间质肿瘤；免疫组织化学

For the first time, we found that the mosquito was a transmitted infectious media of malignant cells to human and quadrumana. The mosquito's body was full of malignant cells, and transmitted pathway was that the mosquito first spit out malignant cells from its thrusting tube and into human body, then it sucked the blood from human body into its stomach.

本文首次公开垦表，钻研发明蚊子是人类和灵长类动物恶性肿瘤传染媒介，蚊子刺针管内充满恶性肿瘤细胞，蚊子在吸血时入针后须先把针管内的肿瘤细胞吐出，然后才顺利把血液吸入胃内。

The mechanisms of apoptosis of skin squamous cell carcinoma induced by IFN-γand ATRA Introduction and objective Skin squamous cell carcinoma is a malignant neoplasm derived from epidermal keratinocyte and squamous cells of skin appendant organ .It is one of the most common skin carcinoma, and the incidence rate of SCC is 20% in malignant non-melanoma.
