1、青岛大学硕士学位论文人类胰腺癌和肝癌组织中多环芳烃含量的测定及意义姓名:刘顺涛申请学位级别:硕士专业:临床检验诊断学指导教师:伦立民20120529人类胰腺癌和肝癌组织中多环芳烃含量的测定及意义捅要目的探讨多环芳烃(PAHs)在人类胰腺癌和肝癌发生过程中的作用。方法胰腺癌和肝癌的癌组织、癌旁组织、非癌胰腺和肝组织中PAils分别经超声提取,固相萃取净化和高效液相色谱荧光分析。结果在标本中共检出4种PAHs,分别是崖、2一甲基葸、芘和苯并(a)芘。4种PAl-ls在胰腺癌组织与癌旁胰腺组织中含量差异无统计学意义(P>O.
2、05);2一甲基葸、芘和苯并(a)芘在胰腺癌组织、癌旁胰腺组织中的的含量高于非癌胰腺组织,差异有统计学意义(P<0.05);扈在胰腺组织三组标本中的含量差异无统计学意义(P>O.05);4种PAHs在肝组织的三组标本中含量差异无统计学意义(P>0.05)。结论人类胰腺组织和肝组织中存在PAlls,人类胰腺组织和肝组织对PAHs有很强的生物富集能力;PAHs与人类胰腺癌的发生可能有一定相关性而与肝癌的发生可能无相关性。硕士研究生刘顺涛(临床医学检验诊断学)指导教师伦立民教授关键词t胰腺癌;肝瘤;多环芳烃;高效液相色谱TH
