| 摘 要： | 目的探讨载多西紫杉醇脂质微泡（DLLM）联合超声靶向微泡破裂（UTMD）对兔VX2肝癌微血管的抑制作用。方法建立60只兔VX2肝癌动物模型,将其随机分为6组（n=10）：单纯药物组（Doc组）、单纯载药微泡组（DLLM组）、药物＋超声组（Doc＋US组）、单纯微泡＋超声组（PLM＋US组）、载药微泡＋超声组（DLLM＋US组）及对照组,比较各组动物肿瘤组织的血管密度（MVD）、CD34及VEGF的表达。结果处理后DLLM＋US组的CD34表达水平低于其他各组,MVD明显降低,与其他各组相比差异有统计学意义（P〈0.01）;DLLM＋US组的VEGF表达水平明显低于其他各组（P〈0.01）。结论 DLLM联合UTMD能抑制兔VX2肝癌的微血管生成,从而抑制兔VX2肝癌的生长。 |

| Abstract: | Objective To observe the inhibition effect of docetaxel-loaded lipid microbubbles (DLLM) combined with ultrasound targeted microbubbles destruction (UTMD) on microvessel in rabbit VX2 liver tumor models. Methods Sixty rabbits were randomly divided into 6 groups (n=10), i.e. Doc group (used docetaxel only), DLLM group (used docetaxel-loaded lipid microbubbles), Doc+US group (used docetaxel combined with ultrasound positioning irradiation), PLM+US group (used microbubbles combined with ultrasound positioning irradiation), DLLM+US group (used docetaxel-loaded lipid microbubbles combined with ultrasound positioning irradiation) and control group. The expression of CD34 and VEGF and microvessel density (MVD) were compared among different groups. Results After treatment, the expression of CD34 in DLLM+US group was lower, the MVD of DLLM+US group was markedly lower than that of the other groups (P<0.01), while the expression of VEGF in this group was the lowest among all 6 groups (P<0.01). Conclusion DLLM combined with UTMD can inhibit the generation of microvessels in rabbit VX2 liver tumor, thus inhibit the growth of the tumor. |
