1、周宏華原發(fā)性肝癌患者外周血Treg、MDC、PDC細胞水平變化及意義原發(fā)性肝癌患者外周血Treg、MDC、PDC細胞水平變化及意義中文摘要目的：檢測乙肝相關性原發(fā)性肝癌(Primaryhepaticcarcinoma，PHC)患者外周血調節(jié)性T細胞(regulatoryTcells，Treg)、漿細胞樣樹突狀細胞(plasmacytoiddendriticcell，PDC)2及髓樣樹突狀細胞(myeloiddendriticcell，M

2、DC)的表達，初步分析探討PHC患者外周血Treg、MDC、PDC細胞水平變化及意義。方法：收集江蘇省蘇北人民醫(yī)院肝脾內科乙肝相關性PHC合并肝硬化患者30例(I組)、乙肝肝硬化患者16例(11組)、健康體檢者20例(ill組)外周血標本，采用流式細胞術檢測PHC合并肝硬化患者(I組)、乙肝肝硬化患者(II組)、健康體檢者(Ⅲ組)外周血Treg、MDC、PDC細胞百分比，結合患者資料初步分析其意義：(1)三組外周血Treg、MDC、PD

3、C細胞百分比表達；(2)PHC組Treg細胞與MDC、PDC細胞百分比表達水平相關性：(3)PHC組腫瘤直徑與T／eg、MDC、PDC細胞百分比表達水平相關性：(4)PHC組患者HBVDNA載量與Treg、MDC、PDC細胞百分比表達水平相關性。結果：l、三組外周血中Treg細胞百分比檢測：Treg細胞在PHC組(856士187)％高于肝硬化組(6。77j：239)％和對照組(422土124)％，差異均有統(tǒng)計學意義(PO05)。3、三組

4、外周血中PDC細胞百分比檢測：PDC細胞在PHC組(O13士007)％低于對照組(034=1009)％、肝硬化組(017士007)％低丁對照組、PHC組低于肝硬化組，差異有統(tǒng)計學意義(尸005；，=033，P005)。5、PHC組腫瘤直徑與Treg、MDC、PDC細胞亞群百分比相關性：腫瘤直徑與Treg細胞呈顯著正相關(r=0992，P005；，=0289，PO05)。6、PHC組HBVDNA與Treg、MDC、PDC細胞亞群百分比相關

5、性：HBVDNA與Treg、MDC、PDC細胞均無顯著相關性(r=O053，P005：r=0423，P005；r=0238，P005)。結論：TheexpressionandsignificanceoftheTreg、MDC，PDCcellsintheperipheralbloodofpatientswithprimaryhepaticcarcinomaABSTRACTObjective：Toinvestigatetheproporti
