1、青岛大学硕士学位论文血清胃蛋白酶原和胃癌相关抗原的联合检测对胃癌诊断的研究姓名:王云峰申请学位级别:硕士专业:免疫学指导教师:高美华20120529摘要目的探讨血清胃蛋白酶原(PG)及其亚群(PGI、PGI/PGII)和胃癌相关抗原(MG7-Ag)的联合检测对胃癌的诊断价值及预后判断的意义。方法采用乳胶增强免疫比浊法检测PG(PGI、PGI/PGII)及ELISA法检测MG7一Ag在各受试者血清中的含量,将结果用统计学方法处理。结果胃癌组的血清PGI、PGI/PGII(PGR)含量明显低于各对照组,该差异有非常显著性(Pm01);萎缩性胃炎组血清PGI、PG
2、R含量明显低于健康对照组、胃溃疡组及浅表性胃炎组,差异有显著性(尸以05);胃溃疡组和浅表性胃炎组的血清PGI含量明显高于健康对照组,差异有显著性(P以05)。胃癌组血清MG7一Ag含量明显高于各对照组,该差异有非常显著性(P以01);萎缩性胃炎组血清MG7一Ag含量明显高于健康对照组、胃溃疡组及浅表性胃炎组,差异有显著性(尸以05)。联合检测阳性率最高为90%。胃癌患者血清中PGI、PGR、MG7一Ag含量与年龄及性别无显著性差异(尸>晓05)。胃癌患者术后PGI含量很低,MG7-Ag含量也明显降低,差异有非常显著性(P以01),但当胃癌复发后PGI及MG
3、7一Ag含量均明显升高,与复发前比较差异有显著性(尸以05)。结论(1)血清PGI、PGR和MG7-Ag的联合检测有助于胃癌的早期诊断及与胃部良性病变的鉴别诊断。(2)胃癌患者血清PGI、PGR和MG7-Ag的联合检测阳性率远远高于单一项目的检测阳性率。(3)血清PGI、PGR和MG7-Ag的联合检测有助于判断术后胃癌的复发和转移。关键词:胃癌;PGIMG7-Ag;硕士研究生:王云峰(免疫学)指导教师:高美华教授AbstractObjectiveThethesisaimstOdevelopajointdetectionofserumpcpsinogen(PG
