2、在CD4T细胞的比例,分析不同TNM分期恶性肿瘤患者外周血中CD4CD25CD127Treg占CD4T细胞的百分比,采用实时荧光定量RT—PCR技术检测PBMC转录因子Foxp3表达水平。结果肿瘤患者外周血中CD4CD25CD127Treg占CD4T细胞百分比为(6.19土1.82),明显高于对照组(3.12-+-1.16)%,差异具有统计学意义(P<0.05)。其中Ⅲ、Ⅳ期患者外周血CD4CD25CD127Treg百分比分别为(6.08士2.14)、(6.88土2.65),明显高于I一Ⅱ期患者(5.65±1.86),P3、(6.72士2.60),明显高于高分化者(5.94±2.11),P4、characterizedifferentpopulationsinhumanperipheralbloodwithCancerJIANGYan—li,LIULei,WANGXue—ye.(1.OncologyDepartmentofJilinProvinceHospital;2.TumorbiotherapycenterofJilinProvinceHospital,Changchun130021,China)Abstract:ObjectiveThisstudyisassignedtoinvestigatethechangesofCD4CD25CD127。Treginperiphera5、lbloodfromcancerpatientsandexploreitsclinicalsignificance.MethodsTheproportionofCD4+CD25+CD127kTreginCD4+Tcellsinperipheralbloodweremeasuredbyflowcytometryin74tumorpatientsand35casesofnormalpeo—pieascontro1.Foxp3expressionweredeterminedbyquantitativereal?timePCR.ResultsTheratioofCD4CD25CD127Tregin6、CD4Tcelloftumorpatients(6.194-1.82)wasobviouslyhigherthanthatinthehealthycontrolgroup(3.12±1.16)。thedifferencewasstatisticallysignificant(P7、.Withpathologicalclassification,CD4CD25CD127Treglevelinthepoorlydifferentiatedishigherthanthatinthehighdifferentiated(6.72-t-2.6Ovs5.94±2.11,P<0.05).CD4CD25CD127。Treglevelinthepatientswhogotlymphnodemetastasisish
