简介：目的：比较卵巢癌SK-OV-3细胞在2D和3D培养系统中的生长特性。方法将卵巢癌细胞株SK-OV-3分别采用2D和3D培养系统进行培养，观察细胞生长形态。采用CCK-8法测定细胞生长，Brdu法检测细胞增殖，流式细胞术检测细胞周期分布。结果SK-OV-3细胞在2D培养系统中呈单层贴壁生长；在3D培养系统中形成多细胞球样体（muti-cellularspheroid，MCS），生长速度较2D培养系统慢。在2D培养系统中SK-OV-3细胞的S/G2-M期细胞比例为（53．7±5．8）％，明显高于在3D培养系统中S/G2-M期细胞比例[（40．9±2．0）％，P＜0．05]。结论不同的培养方式对卵巢癌细胞的生长具有较大的影响。MCS三维培养系统能更好地模拟体内肿瘤细胞的生长状况，是卵巢癌研究的良好平台。

简介：目的探讨3D打印技术在乳腺外科精确手术治疗中的意义。方法2例女性患者均是经查体、B超检查发现右侧乳腺有占位性病变,疑为恶性,要求手术切除。行多排CT胸部平扫、乳腺3.0TMR平扫＋增强检查获得CT和MRI的DICOM数据,输入计算机进行立体模拟建模,而后打印,据此精准定位后手术。结果3D重建模型能清晰地显示乳腺解剖结构、肿瘤所在的三维空间及周围血供。精准定位后完整切除肿瘤,最大限度地保全腺体组织,手术时间大为减少。结论3D打印技术应用于乳腺肿瘤的手术治疗,能够清晰显示出解剖结构,辨识肿瘤毗邻血管,避免遗漏病灶,更有效地辅助术前规划,对提升乳腺复杂手术的安全性、加快手术速度,提高手术精确性有益,在乳腺外科精确手术治疗方面具有极大的应用前景。

简介：目的探讨黄芩素对结肠癌HT-29细胞增殖、迁移能力的影响。方法MTT法观察黄芩素（5、10、20、40、80μg/ml）对HT-29细胞的增殖抑制作用,Transwell试验评价黄芩素（80μg/ml）对HT-29细胞迁移能力的抑制作用,Westernblotting检测黄芩素（20、40μg/ml）对HT-29细胞中信号转导与转录激活因子3（STAT3）、核因子（NF）-κB和p53蛋白表达的影响。同时以未加黄芩素为对照组。结果与对照组比较,黄芩素对细胞增殖能力有抑制作用,增殖抑制率随浓度升高而增加,差异均有统计学意义（P〈0.05）;黄芩素处理后的细胞迁移能力及STAT3和NF-κB蛋白水平均降低,p53蛋白水平升高,与对照组的差异均有统计学意义（P〈0.05）。结论黄芩素可显著抑制HT-29细胞的增殖、迁移能力,可能与上调细胞中p53、降低STAT3和NF-κB蛋白的表达有关。
