目的 探讨微泡增强的超声空化对荷瘤兔乳腺癌的治疗效果。方法 建立兔VX2乳腺癌模型,肿瘤兔随机分成两组,超声微泡组及单纯超声组,各组于治疗前及治疗后分别行超声造影,分析造影前后肿瘤灌注情况。结果 超声微泡组治疗前后造影灰阶值改变明显,造影灰阶值从治疗前的(20.26±2.59)降至(3.71±1.61)(P<0.01);而单纯超声组肿瘤造影灰阶值无明显统计学差异(P>0.05)。结论 微泡增强的超声空化对荷瘤兔乳腺癌有一定的治疗效果。
Objective To investigate the treatment effect of microbubbles-enhanced ultrasound cavitation on VX2 breast tumor in rabbits. Methods The rabbit model of VX2 breast tumor were established. The rabbits were randomly divided into two groups, microbubbles-enhanced ultrasound (US+MBs) group and standard ultrasound (US) group. The VX2 breast tumor perfusion were imaged and assessed using contrast enhanced ultrasonography (CUES) before and after treatment. Results The contrast enhanced grayscale value (GSV) of VX2 breast tumors decreased significantly in the US+MBs group, from 20.26±0.59(before treatment) to 3.71±.761 (after treatment)(P<0.01). While there was no significance of GSV before and after treatment (P>0.05) in the US group. Conclusion Microbubble-enhancement ultrasound cavitation has a certain therapeutic effect on the VX2 breast tumor in rabbits.
