1、·临床论著·青蒿素对支气管哮喘外周血Treg/Th17的调控机制支4士商吴世满【摘要】目的探讨青蒿素对支气管哮喘患者外周血Treg/Thl7表达的调控机制方法将随访的145例哮喘患者按照ACT评分分成完全控制组、部分控制组、未控制组,再从每组中按性别、年龄、BMI匹配随机分别抽取20例、2l例、7例作为研究对象,入选同期于医院就诊的哮喘急性发作期患者18例和医院体检的健康成人19例作为对照组。流式细胞术检测各组CD4T淋巴细胞Treg和Thl7的表达,将CD4T淋巴细胞用一定浓度的青蒿素干预共培养24h检测对比。结果未控制组及急性发作期哮喘患者外周血CD4T淋巴细胞
2、Thl7比例明显高于正常对照组、完全控制组及部分控制组哮喘患者(P<0.05),Treg比例明显低于正常对照组、完全控制组及部分控制组(P<0.05);完全控制组及部分控制组哮喘患者外周血CD4+T淋巴细胞Treg比例稍低于正常对照组(P<0.05),而Thl7比例较正常组差异无统计学意义(P>0.05);与青蒿素共浴培养24h后,未控制组哮喘患者CD4T淋巴细胞中Thl7较干预前明显减低(P<0.05),Treg较干预前明显升高(P3、hl7较干预前差异无统计学意义(P>O.05),Treg较干预前差异无统计学意义(P>0.05);完全控制组哮喘患者Thl7较干预前稍减低(P<0.05),Treg较干预前差异无统计学意义(尸>O.05)。结论青蒿素在体外对支气管哮喘,尤其是难治性哮喘的外周血CD4T淋巴细胞中Treg/Thl7有一定的调控作用,并在一定程度上可改善难治性哮喘患者CD4T淋巴细胞中Treg/Thl7免疫失衡。【关键词】青蒿素;哮喘;T淋巴细胞,调节性;CD4T淋巴细胞:Thl7;肺功能InvitrostudyintheregulationofartemislninORbronchia4、lasthmaofperipheralbloodThl7/TregLiuJuan;WuShiman.ShanxiMedicalUniversity,Taiyuan030001,ChinaCorrespondingauthor:WuShiman,Email:wushim硎@163.com[Abstract]ObjectiveTodetectinvitrostudyintheregulationofartemisininonbronchialasthmaofperipheralbloodThl7/Treg.MethodsAccordingtotheasthmacontr5、oltest(ACT)scores,followed-up145patientswithasthmaweredividedintocontrolled,partlycontrolledanduncontrolledgroup,thenwhichwereselectedrandomly20,21,and7casesasthestudyonesbySeX,ageandBMImatching,meanwhile18patientswithacuteexacerbationofasthmaand19healthyadultsasthecontro1.Artemisinina6、ndCD4Tlymphocyteswereco-culturedfor24hours,usedflowcytometrytodetecttheexpressionofThl7andTrcgandcomparedwithnoco—cultured.ResultsThl7ratioinCD4Tlymphocytesoftheperipheralbloodinuncontrolledgroupandacuteexacerbationofasthmawassignificantlyhigherthanthatofothergroups(P<0.05),andTregrati7、oinwhichwassignificantlylowerthanthatofothergroups(P<0.05).Meanwhile.TregratioinotherasthmaticgroupswasslightlylowerthanthatofnormalgroupfP<0.05).AfterArternisininandCIMTlymphocyteswereco—culturedfor24hours,Thl7ratioinuncontrolledgroupandacuteexacerbationofasthmaWassignificantlydecre
