2、微泡超声造影检查及超声辐照;C组:载VEGFR-2单克隆抗体脂质微泡超声造影及超声辐照。所有模型均用红色荧光蛋白标记。辐照前、辐照后1周分别行实时超声造影和荧光摄片检查,动态存储造影图像进行声学定量脱机分析,获取峰值强度(PEAK)、局部血容量(RBV)、局部血流量(RBF)等造影参数加以比较:测量肿瘤大小、荧光面积、荧光强度及血管密度,加以比较。结果1造影结果分析t辐照前A、B、C三组的PEAK、RBV、RBF三个指标进行组间两两比较,差异均无统计学意义(胗0.05);A组假照1周后PEAK、RBV、
3、RBF明显高于假照前,差异有统计学意义(P4、差异无统计学意义(胗O.05)。C组辐照后肿瘤长径、荧光面积、荧光强度及血管密度均较假照前明显减少,差异有统计学意义(P<0.05);空化治疗后A、B、C三组的各指标行组间两两比较,差异均有统计学意义(氏0.05)。结论靶向超声微泡联合超声辐照可以增强VEGFR.2单克隆抗体对结肠癌的治疗效果。关键词超声检查;超声造影;靶向微泡;超声辐照;结肠癌温州医学院硕士学位论文PreliminaryStudyontreatingsubcutaneouscoloncancerxenograftsinnudemice5、usingultrasoundradiationcombinedwithVEGFR一2antibody·carryingtargetedmicrobubblesAbstractObjectiveToinveStigmethetherapeuticefficacyofsubcutaneouscoloncancerxenograftsinnudemiceusingultrasoundradiationcombinedwithVEGFR.-2antibody..carryinglipidmicrobubble6、s.Methods90Balb/cnudemicewhichsuccessfullyestablishedthecolontumorxenograftssubcutaneouslywerestochasticallydividedintothreegroups,30eachgroup:GroupAwasascontrol,underwentcontrast—enhancedultrasound(czus)examinationandshamultrasoundradiation.GroupBWasgiv7、enCEUSexaminationusingbarelipidmicrobubblescombinedwithultrasoundradiation.GroupC:WasgivenCEUSexaminationusingVEGFR-2antibobycarryinglipidmicrobubblescombinedwithultrasoundradiation.Redfluorescentprotein(RFP)waslabeledtoallthenudemicemodel.Foreverymouseo8、feachgroup,real-timeCEUSexaminationandFlurographywasperformedthedaybeforetheultrasoundradiationisgiven,andthen,repeatedoneweeklater.FortheCEUS,theimageswasstoreddynamically,andthenacousticquantitativeoffiineanalysiswasdone
