1、河北医科大学硕士学位论文肝癌患者手术治疗前后CD4+CD25+Tregs的变化及意义姓名:刘昭明申请学位级别:硕士专业:外科学指导教师:邢宏利201203中文摘要肝癌患者手术治疗前后CD4+CD25+Tregs的变化及意义摘要目的:观察肝癌患者手术治疗前后CD4+CD25+Tregs的变化。探讨手术治疗与患者免疫之间的关联性及意义。方法:收集2010年12月.2011年12月在衡水市哈励逊医院住院的肝细胞肝癌患者,男15例,女5例;正常对照组20例,来自衡水市哈励逊健康体检者。入组标准:l、肿瘤
2、单发<5cm,或病灶小于3个,每个病灶均<3cm。应用全自动生化分析仪检测血清—岍水平;酶联免疫法检测HBV血清学标志物:HBsAg、HBsAb、HBeAg、HBeAb、HBcAb;定量PCR分析检测HBVDNA载量。并检测抗.HAV、抗.HCV、抗.HDV、抗.HEV、抗.HIV,以除外其它嗜肝病毒及HIV感染。外周血CD4+CD25+Tregs频率的测定:取外周肝素抗凝血,应用CD4、CD25免疫荧光抗体染色,红细胞裂.解液溶解红细胞,完全溶血后加0.02M磷酸盐缓冲液洗涤,应用加多聚甲醛.
3、磷酸盐缓冲液固定,重新悬浮细胞,上流式细胞仪检测,淋巴细胞射门,分析CD4+T细胞中CD4+CD25+T细胞的百分比。应用SPSS17.0统计软件对实验数据进行分析,所有数据采用均数4-标准差表示,组间比较采用单因素方差分析。以P<0.05为差异有统计学意义。结果:Treg细胞在肝癌患者手术前后数量变化CD4+CD25+T细胞在肝癌患者中所占Lt',侈tJ(10.45士3.23)%较正常对照组(2.36士0.89)%明显升高(P4、统计学意义。术后2周(6.98士2.56m较术前明显下降(P5、mberchangeofCD4+CD25+RegulatoryTCellafterOperationinHepatocarcinomaPatientstherapyABSTRACTObjective:TodetectthenumberchangeofCD4+CD25+TcellafteroperationanddiscusstheeffectofoperationonimmuneresponseofpatientswimHCC.Methods:20HCCchronichepatitisBpati6、entswhichincluded15menand5womeninharisonHospitalfromDecember2010toDecember201wereenrolledinthisstudy.And20healthpeoplewasenrolledfromharisonHospitalHealthycheck-upcenter.Serum随弋WasmeasuredusinganOlympusAU2700auto—biochemicalanalyzer.HBVmarkers:HBsAg、7、皿sAb、HBeAg、HBeAb、HBcAb,anti—HAV,anti-HCV,anti—HDV,anti-HEVandanti—HIVweredetectedbycommercialenzymeimmunoassaykitsrespectively.Peripheralheparinizedbloodsampleswerecollectedfromalltheenrolledindividuals.ForstainingofCD4+CD25十Tregs,FITC—anti-CD4andPE-8、anti—CD25wereused.Afteralltheredbloodcellsweredissolved,0.02Mphosphatebuffersaline(PBS)WaSusedtowashthebloodsamples,thentheremainingcellswerefixedinparaformaldehyde—PBSandthefrequencyofCD4十CD25十Tcellsweredetectedbyflowcytometricanalysis,gatedfromIymp
