  • liver cancer surgery With the maturity and development of liver cancer surgery, the treatment methods and means of liver cancer are becoming more and more abundant, and are no longer limited to a single surgical treatment. Liver resection and liver transplantation are still the main methods for treatment of liver cancer patients, but minimally invasive treatment, percutaneous transcatheter arterial chemoembolization and other technical methods, as an important supplement to surgical treatment, have also been widely used, they are created for patients. Surgical treatment opportunities, reduction or reduction of tumor recurrence and metastasis have played a role in extending the survival time of patients. Even so, patients with liver cancer have a concealed disease, no obvious symptoms, and most patients have lost the opportunity to undergo radical surgery.

Description

检测多肽标志物抗原的 EL I SA试剂盒 技术领域
本发明属于生物技术领域, 具体涉及检测多肽标志物抗原的 ELISA试剂盒。 背景技术
随着肝癌外科的成熟和发展, 肝癌的治疗方法和手段日渐丰 富, 而不再局限于单一的手术治疗。 肝切除术和肝移植仍然是肝癌 患者治疗的主要方法, 但微创治疗、 经皮肝动脉化疗栓塞等技术方 法, 作为手术治疗的重要补充, 也得到了较广泛的应用, 它们在为 患者创造手术治疗机会、 降低或减少肿瘤的复发和转移等方面都起 到了一定的作用, 延长了患者的生存时间。 虽然如此, 肝癌患者发 病隐匿、 无明显症状、 多数患者就诊时已失去手术根治的机会。 因 此, "早期发现、 早期诊断、 早期治疗" 是降低癌症死亡率的重要 措施。 筛选和建立用于癌症早期诊断的、 高敏感、 高特异的血清学 诊断技术, 提供癌症早期预警普查, 具有重大意义和巨大市场前 景。
目前国内外广泛采用检测血清中甲胎蛋白 (AFP ) 来确诊肝癌 ( HCC ) , 尽管这种方法提高了 HCC的检测水平, 但仍有显著数量 患者的甲胎蛋白并未升高, 尤其对肿瘤直径小于 3CM 的小肝癌患 者, 其敏感性及特异性更低。 近年来, 标志物联检在肿瘤诊断中的 应用的研究得到很大的重视。 如通过联检甲胎蛋白 (AFP)、 癌胚抗原 (CEA)、 血清铁蛋白 (SF)、 α-L-岩藻糖苷酶 (AFU)可显著提高肝癌诊 断的阳性率。 AFP、 CEA、 SF、 CA等四标志物联检原发肝癌的实验 也获得不错的结果。 但由于诊断特异性或成本效益方面的原因, 很 难在肝癌普查中广泛应用。
血清中丰富的多肽资源在目前重大疾病诊断中扮演重要的角 色。 采用目前常规的临床手段进行多肽检测逐渐引起学术界和医药 界的高度重视, 基于多肽的肿瘤诊断技术正开始向临床应用高速发 展, 肿瘤的早期预警技术也在开发之中, 一些多肽的联合应用有可 能为肿瘤等重大疾病的预警提供革新性的突破。 血清中多肽同血清 中蛋白不同, 其分子量低于 10000Da, 结构简单, 变化多样。 是否 能够采用目前常规的临床手段进行检测仍在探索。
目前, 检测血清中多肽进行临床诊断还没有先例。 血清多肽能 否用于诊断或早期诊断肝癌可以从三个方面来判断。 1、 血清多肽是 血清蛋白的降解产物或基因直接编码产物。 当生理状态发生变化时 尤其向肿瘤转化时, 蛋白的代谢发生变化, 导致多肽相应变化, 从 而建立了多肽——疾病的相关关系, 因此, 多肽可以像蛋白一样进行 疾病诊断。 2、 实践上已经有一些疾病的诊断采用多肽标志物, 1985 年以来, 利用合成多肽检测艾滋病病毒 (P24 ) 、 风疹病毒、 人巨细 胞病毒及类风湿等已应用到临床。 3、 文献表明, 多肽可以用于临床 诊断, 如, Clinical Chemistry 51:10 , 1933-1945(2005)和 Clinical Chemitry 53:61 , 067- 1074(2007)认为血清多肽标志物能更精确的区 分蛋白标志物不能区分的肿瘤。 Nat Methods .2008 Jan;5(l):57-9认 为质谱诊断肿瘤甚至比 MRI还好。 质谱技术给生命科学带来的促进 作用举世公认, 近十年来, 质谱在新生二筛查、 基因突变检测方面 取得一系列重要进展, 并出现了单核苷酸多态性(SNP )分析专业质 谱仪器, 显示了质谱在临床诊断方面的价值。
基于血清多肽抗原的肿瘤早期诊断试剂盒是当前最受关注的肿 瘤早期诊断技术之一。 目前临床领域中单一标志物始终存在着特异 性不强、 阳性率较低等不足, 特别是对早期肿瘤的检测率不高, 多 标志联合检测事在必行, 但苦于没有一个很好的手段实现同时检 测。 2006年 Josep Villanueva等人对 32例前列腺癌、 21例乳腺癌和 20例膀胱癌血清多肽研究, 发现 14个、 10个和 58个可分别作为前 列腺癌、 乳腺癌和膀胱癌的肿瘤标志多肽, 预测准确率为 100%。 血 清中存在的丰富的多肽为肿瘤预警和早期诊断提供了丰富的标志物 资源, 这些多肽的联合应用有可能为肿瘤等重大疾病的预警提供革 新性突破。 经研究发现, 序列为 Asn-Leu-Giy-His-Gly-His-Lys- His-Glu-Arg-Asp-Gln-Gly-His-Gly-His-Gln 的多肽是癌症重要血清多 肽标志物之一。
近几年兴起的血清多肽组学已成功应用于几种癌的诊断研究, 如乳腺癌, 卵巢癌, 前列腺癌等, 主要釆用的是表面增强激光解吸 离子化(SELDI )技术和免疫磁珠技术, 但该体系存在价格昂贵, 不 利推广的缺点。 发明内容
