简介：Objective:Toinvestigatetheeffectofactivation-in-ducedcelldeath(AICD)oncellularimmunefunctioninthecondylomaacuminatum(CA).Methods:Peripheralbloodmononuclearcells(PBMC)wereisolatedfromnormalhealthyindividuals(controlgroup)andpatientswithCA.PBMCwereculturedwithPHA-Pfor48hinvitro.ApoptosisofthePBMCwasdetectedbyflowcytometry.Supernatantcytokines(IL-2andIL-10)wereassayedbyELISA.Results:TherateofPBMCapoptosisinbothCAgroupandcontrolgroupinfreshPBMCwasverylowandsimilarinbothgroups(P>0.05).TherateofPBMCapoptosiswithintheCAgroupwasnoticeablyincreasedcomparedtothatofthecontrol(P<0.001)afterPBMCwereculturedfor48h.ThelevelofIL-2wassignificantlylowerintheCAgroupthaninthecontrolgroup(P<0.001),ThelevelofIL-10wassignificantlyhigherintheCAgroupcomparedtothecontrolgroup(P<0.001).Conclusion:StudyresultsindicatethatAICDmayaffectcellularmediatedimmunefunctionandplayanimportantroleinthepathogenesisofCA.

简介：Abstract:Thisstudyinvestigatedtherelationshipbetweenhumanpapillomavirus(HPV)genotypeandexpressionofp53andp21^WAH1.Expressionofp53andp21^WAH1in35casesofcondylomaacuminatumspecimensinfectedbyHPV6/llandHPV16/18werestudiedusingimmunohistochemicalstaining.Allspecimensofthecondylomaacuminatumcasewerepositiveforexpressionofp53andp21^WAH1.Theexpressionofp53incondylomaacuminatuminfectedbyHPV16/18wassignificantlylowerthanthatinspecimensinfectedbyHPV6/ll.However,expressionofp21wAHbetweenthetwogroupswasnotsignificantlydifferent.Expressionofp53incondylomaacuminatumislikelyrelatedtoHPVgenotype,expressionofp21^WAH1wasnotrelatedtoHPVgenotype.

简介：Objective:Tostudytheexpressionlevelsofplatelet-derivedgrowthfactor(PDGF)andgranulocytecolony-stimulatingfactor(G-CSF)inperipheralbloodandtheirroleinthepathogenesisofCondylomaacuminatum(CA).Methods:Seraweretakenfrom70patientswithCondylomaacuminatumandcomparedwith35healthycontrols.PDGFandG-CSFinserumwerequantitatedusingadualantibodysandwichenzyme-linkedimmunoabsorbentassay(ELISA).Results:SerumconcentrationsofPDGFandG-CSFweresignificantlyincreasedinpatientswithCondylomaacuminatum(CA)comparedtocontrols(P<0.001andP<0.005respectively).SerumlevelsofPDGFandG-CSFcorrelatedwithclinicalseverityofCA,butnosignificantdifferencewasobservedbetweendifferentdurationofdiseasegroups.AsignificantpositivecorrelationwasnoticedbetweenneutrophilcountandG-CSFlevels(γ=0.38,P<0.001),andtheneutrophilcountshowednosignificantcorrelationwithPDGF.Conclusion:TheresultsindicatedthatincreasedexpressionofPDGFandG-CSFinperipheralbloodmightbeinvolvedinpathogenesisofCA.
