Preparation of monoclonal antibodies against mouse alpha-fetoprotein and preliminary study on their application [PDF]

open access: yes, 2016
原发性肝癌是我国高发的恶性肿瘤之一,每年新发和死亡患者均占全球总数的一半以上。根据全国肿瘤登记中心最新公布的2015年《肿瘤登记年报》数据,我国肝癌新增病例为46.61万,占所有恶性肿瘤的第4位(10.86%),而死亡病例为42.21万,占所有癌症死亡的第3位(15.00%),仅次于肺癌和胃癌。尽管近年来肝癌的诊断和治疗有了一定的进展,其预后仍然不理想,五年生存率极低。究其原因,大部分肝癌患者往往在疾病的晚期才被诊断出来,有些甚至发生了远端转移,因而错过了最佳治疗时机;此外 ...

The expression and clinical significance of SATB2 in Esophageal Squamous Cell Carcinoma [PDF]

open access: yes, 2015
摘要 研究目的:食管癌在中国是一种高发的消化系统恶性肿瘤。由于解剖位置深、临床症状隐匿、早期症状不明显、易以多种路径转移、高位癌手术残留、术后容易复发以及放化疗不敏感等特点,食管癌预后较差。因此,进一步深入研究食管癌发生发展、侵袭转移以及预后评估因素的内在机制具有重要的意义。SATB1是富含AT序列结合蛋白的特殊家庭成员之一,已被证明影响众多肿瘤致瘤性的过程。SATB2与肿瘤的关系密切一直是研究的关注点,然而,其在食管鳞状细胞癌组织中的作用不清楚。本论文以食管鳞癌为研究对象,以SATB2为切入点 ...
