摘要
Objective:Toinvestigatetherelationshipbetweenapoptosisandproliferatingcellnuclearantigen(PCNA)expressionofkeratinocytesinCondylomataacuminata(CA).Methods:PCNAexpressionwasobservedbyimmunohistochemistrytechnique(ABCmethod)in51CAspecimensand18normalspecimensofforeskinorvaginalmucosae.55specimens(40intheCAgroupand15inthecontrolgroup)wererandomlysampledforinsitulabelingofapoptoticcellsusingtheTUNELmethod.Results:PositiveexpressionofPCNAinCAandcontrolgroupswere90.2%and77.8%,respectively,andtheproliferationindexinCAgroupwassignificantlyhigherthanthatinthecontrolgroup(P<0.001).Thepositiverateofapoptosiswas42.5%intheCAgroupand53.3%inthecontrolgroup,andtherewerenosignificantdifferencesintheapoptoticindexandapoptosis-proliferationratiobetweentwogroups(P>0.05).Theproliferationindexshowedasignificantnegativecorrelationwiththeapoptosis-proliferationratio(r=-0.62,P=0.01)intheCAgroup.Conclusion:ItissuggestedthattheproliferativeappearanceofCAcouldbeduetotheimbalancebetweencellgrowthandcelldeathwhichiscausedbymoreproliferationandlessapoptosisinkeratinocytes.
