2、静脉血Th17、Treg细胞频率,并分析其与肝炎临床指标的相关性。22例慢性乙型肝炎患者(CHB)和23例健康体检者(HC)作为对照。结果1)在治疗基线时,ACLF组和CHB组Treg细胞表达均低于健康对照组(P<0.01和P<0.05),ACLF组的Treg细胞表达低于CHB组(P<0.05),Thl7细胞在CHB组、ACLF组的表达均高于健康对照组,但差异无统计学意义(P>0.05)。Th17/Treg比值在ACLF组和CHB组高于健康对照组(P3、1)。2)ACLF存活组中Th17细胞表达、Th17/Treg比值随着病程逐渐降低并维持在较低水平,Treg细胞的表达逐渐升高并维持在较高水平;ACLF死亡组中Thl7细胞表达、Th17/Treg比值逐渐升高并持续处于较高水平,Treg细胞表达持续处于较低水平。3)在CHB组和ACLF组中总胆红素与Th17/Treg比值呈正相关,凝血酶原活动度与Th17/Treg比值呈负相关,乙型肝炎病毒载量与Th17freg比值无相关性。谷丙转氨酶与CHB组的Th17/Treg比值呈正相关。结论Th17/Treg细胞数量严重失衡可能是ACLF发生的4、原因之一,Th17/Treg比值有望成为判断ACLF预后的新指标。【关键词】乙型肝炎;肝衰竭;Th17细胞;Treg细胞;临床转归【中图分类号】R512.6【文献标识码】ATheroleofThl7/TregcellbalanceintheclinicaloutcomeofhepatitisBvirus-associatedacute一0n—chr0nicliverfailureLIUGuangliang.ZHOUXiaolan2,TAOPeng,z.DepartmentofInfectiousDiseases,SecondAffil5、iatedHospitalofChongqingMedicalUniversity,Chongqing400010,China;2.MedicalRecordsDepartment,SecondAffiliatedHaspitalofChongqingMedicalUniversity,Chongqing400010,ChinaCorrespondingAuthor:TA0Peng,E-mail:konghu128@126.com[Abstract]ToinvestigatetheimbalancebetweenTh17cellsan6、dTregcellsduringthedevelopmentofacute——on-chronicliverfailure(ACLF),31ACLFpatients,22chronichepatitisBpatientsand23healthyvolunteerswereinvolvedinthisstudy.Peripheralbloodwascollectedattreatmentbaseline,7,14,21,and28daysafteradmission.ThefrequenciesofThl7andTregcellswer7、edynamicallyanalyzedwithflowcytometricstainingtechniques.AndtherelevancebetweentheThl7/Tregratioandhepatitisclinicalparameterswasanalyzed.Atbaseline,bothinACLFgroupandCHBgroup,thefrequenciesofTregwerelessthanthatinthehealthycontrolgroup<0.01andP<0.05respectively)。whilet8、hefrequencyofTreginCHBgroupwashigherthanthatinACLFgroups<0.os).ThedifferenceofThl7cellfrequencyamongthethreegr
