Objective To investigate the relationship between CD4-CD8-T cells ratio and IL-4, IFN-γ levels in the peripheral blood of patients with pancreatic carcinoma. Methods Floweytometer was used to analyze the CD4-CD8-T cells ratio in the peripheral blood of patients with pancreatic carcinoma and the IL-4 ,IFN-γ levels were detected by ELISA. Results The ratio of CD4-CD8-T cell in CD3+ T cell from 25 pancreatic carcinoma patients was(4.2 ± 1.7) %, the ratio of CD4-CD8-T cell in CD3+T cell from 45 healthy person was(6.3 ± 2.6) %, there was significant deviation between the two groups(P < 0. 01). The IL-4 level of 25 pancreatic carcinoma patients was (86.3 ± 23.3) fg/L,the IL-4 level of 45 healthy person was (56.2 ± 9.2) fg/L,there was significant deviation between the two groups(P <0.01). The IFN-γ level of 25 pancreatic carcinoma patients was (16.4±4.8) fg/L before operation, the IFN-γ level of 45 healthy person was (27.4±3.8) fg/L,there was significant deviation between the two groups(P <0.01). The ratio of CD4-CD8-T cell in pancreatic carcinoma patient after operation was higher than before operation. It could be found negative correlation between CD4-CD8-T cells ratio and IL-4 level in pancreatic carcinoma patient,it could also be found positive correlation between CD4-CD8-T cells ratio and IFN-γ level in pancreatic carcinoma patient. In pancreatic carcinoma patient,the CD4-CD8-T cells ratio and IL-4 level was significant associated with clinical stage (P < 0.05), but no relationship with hisological differentiation (P>0.05), it could be found no relationship between IFN-γ level and clinical stage, hisoiogieal differentiation (P > 0.05). Conclusion The CD4±CD8±T cells ratio in the peripheral blood of patients is decreased,it may be participate in the carcinogenesis and development of pancreatic carcinoma by influence the IFN-γ levels. 相似文献

目的 探讨胰腺癌组织中类肝素酶(heparanase 1,Hpal)表达与胰腺癌侵袭性、临床病理等因素之间的关系.方法 采用逆转录-聚合酶链反应(RT-PCR)、免疫组化(SP)法检测37例胰腺癌患者痛组织、癌旁组织及正常胰腺组织中Hpal表达,并统计分析Hpal表达与胰腺癌侵袭性、临床病理等因素之间的相关性.结果 Hpal在胰腺癌组织、癌旁组织、正常胰腺组织中的表达阳性率分别为64.9%(24/37)、56.8%(21/37)和10.8%(4/37).胰腺癌组织中Hpal表达与胰腺癌TNM分期、侵及神经和血管情况、包膜完整情况以及淋巴转移明显相关(P<0.05),但与患者年龄、性别、组织学分化程度、肿瘤大小无关(P>0.05).结论 Hpal与胰腺癌发生、发展密切相关,Hpal表达与胰腺癌的侵袭性、局部浸润、临床分期以及区域淋巴结转移有密切关系,胰腺癌Hpal过表达可促进胰腺癌浸润生长与转移,其表达对评价胰腺癌预后亦有一定的价值. 相似文献
