摘要:
目的探讨内皮抑素在兔VX2肝移植瘤介入治疗中的应用价值。方法建立兔肝移植瘤模型,随机分为对照组(NS,10只),TACE组(Lipiodol+ADM,10只)和内皮抑素组(Lipiodol+ADM+ES,10只),多排螺旋CT测量肿瘤大小,计算肿瘤增长率(GR);术后1周取出病理标本,利用免疫组化染色及半定量RT-PCR法分别检测残瘤组织微血管密度(MVD)和血管内皮生长因子(VEGF)表达。结果3组肿瘤增长率分别为对照组(270.86±148.94)%,TACE组(-8.91±21.77)%,内皮抑素组(-20.40±36.07)%,3组间相互比较,对照组呈明显正增长,与其余2组比较差异均有统计学意义(P<0.01),而TACE组与内皮抑素组之间差异无统计学意义(P>0.05);各组的MVD值分别为80.00±17.14(对照组)、84.22±16.45(TACE组)和57.00±13.26(内皮抑素组),内皮抑素组MVD值最低,与另外2组比较差异均有统计学意义(P<0.05),对照组和TACE组之间差异性不明显(P>0.05);VEGF165mRNA:对照组为(0.85±0.056),TACE组为(1.10±0.087),内皮抑素组为(0.72±0.065),TACE组表达水平最高,与其余2组比较差异有统计学意义(P<0.01)。结论兔VX2肝移植瘤的介入治疗中应用内皮抑素后,肿瘤明显缩小,肿瘤组织VEGF的表达减低,MVD的分布减少,提高了肿瘤的治疗效果。
