To date,it has been documented after transfusion of unirradiated blood components to at least 87 patients:in patients with severe combined immunodeficiency,thymic hypoplasia,and Wiskott Aldrich syndrome premature newborns and those with erythroblastosis fetalis; patients with hematologic malignancies including Hodgkin\'s and non-Hodgkin\'s lymphomas,acute myelocytic and lymphoblastic leukemias,chronic lymphocytic leukemia,and aplastic patients with solid tumors including neuroblastomas, glioblastoma,rhabdomyosarcoma,cervical carcinoma,small cell lung cancer,and germ cell tumor;patients after cardiac surgery and cholecystectomp-60;and in an apparently healthy 22-year-old woman.

Prepare 131I-labbelled anti-CD20 monoclonal antibody using lodogen iodine labelling;(2)Measure the immunity activation of labbelled antibody by means of both cell combine analysis and LDH cytotoxicity detection kit;(3)Evaluate the injury rate of tumor exposed to 131I-chimeric anti-CD20 monoclonal antibody in vitro. The MTT method and the experiment of cell growth control are used;(4)Record the apotosis of Daudi cell using gelose electrophoresis;(5)Learn the inhibition effect of radioactive medication on the marrow. Radiohnmunoimages are taken on various intervals after injection of the labeled antibodies to the nude mice. The distribution of radioactive medication, I31l-labeled antibodies, in the marrow tissue indicates the inhibition effect. Here a B cell non-hodgkin lymphoma model in nude mice is established by us;(6)28-day observation are done in 3 groups of nude mice model.

(1) 用lodogen标记法制备131I-国产人鼠嵌合抗CD20单抗；(2)采用细胞结合分析法和乳酸脱氢酶法细胞杀伤性实验测定131I标记后国产人鼠嵌合抗CD20单抗与靶细胞的免疫活和利结合能力；(3) MTT法和细胞生长抑制实验测定131I-国产人鼠嵌合抗CD20单抗的体外杀瘤活性；(4)用琼脂糖凝胶电泳法研究131I-国产人鼠嵌合抗CD20单抗致Daudi细胞凋亡；(5)建立荷人B细胞淋巴瘤移植瘤裸鼠模型，应用γ计数法检测注射到荷瘤裸鼠体内的131I-国产人鼠嵌合抗CD20单抗的组织分布情况，明确其靶向性；(6)将荷瘤裸鼠分3组进行放射免疫治疗，分别为阴性对照组、131I-国产人鼠嵌合抗CD20单抗组、国产人鼠嵌合抗CD20单抗组。

Methods:35 cases of otic neoplasms confirmed by clinic and biopsy, including 16 cases of acoustic neuroma, 3 cases of facial nerve neuroma, 10 cases of glomus jugulare tumor, 3 cases of carcinoma of middle ear, 3 cases of congenital cholesteatoma.

术前诊断单纯型16耳，肉芽肿型8耳，胆脂瘤型18耳。26耳诊断为肉芽肿型和胆脂瘤型患者均行手术治疗，术前诊断为肉芽肿型8耳，术后2耳病理证实为胆脂瘤型。18耳胆脂瘤型术后证实有3耳为肉芽肿型。

Giant cell tumor of bone is a kind of common bone tumor,which has characteristics of high recurrence rate and invasion.recently,tumor vessel angiogenesis has been the warm spot of research.genesis,development and metabasis of solid tumor have close relationship with tumor vessel angiogenesis; extracellular matrix degradation is the key point for tumorous infiltration and metabasis;the significant biology characteristic of tumor cell is the disorder of tumor cell differentiation and apoptosis.the correlated research has very important significance for judging gct prognosis and guiding therapy.

骨巨细胞瘤（giant cell tumor of bone，gct）是一种常见骨肿瘤，由于其高复发率和强侵袭性，备受临床骨科工作者的关注。骨巨细胞瘤血管生成是近年来研究热点，实体瘤的发生、发展及转移与肿瘤的血管生成密切相关；细胞外基质降解在肿瘤的浸润和转移中起到关键作用；肿瘤细胞的分化凋亡障碍与无限增殖能力是肿瘤细胞的重要生物学特征。骨巨细胞瘤生物大分子研究的不断深化对判断gct的预后及指导治疗有重要意义。
