中文摘要： 中医临床肿瘤用药中，活血化瘀药占有重要地位，但已有的研究质疑其是否会导致耐药及肿瘤转移。项目前期研究表明：补气活血药配伍使用，不仅能消除活血化瘀药尤破血药带来的负面效应，且能协同增效及延缓转移。本项目对具中医治疗肿瘤特色的补气活血药黄芪及乳香配伍，从细胞、卵巢癌移植瘤模型及代谢组分等观察其对卵巢癌耐药敏感性及侵袭转移的影响。项目创新性地将LC/TOF/MS、PCR等前沿技术首次引入中医药理论研究领域。以siRNA技术沉默WAVE3基因，探讨配伍对卵巢癌移植瘤的抑制率及转移率的影响，以PCR检测耐药相关因子P-gp, MRP, BCRP, LRP及转移相关因子MMP-2、VEGF、FGF2、COX-2的表达，通过整体辨识和靶标分析，利用生物信息数据库解析代谢组分的变化规律，初步探寻黄芪、乳香配伍逆转肿瘤耐药及抑制侵袭转移机理，为丰富和发展中药配伍理论，指导临床安全、有效用药提供科学依据。

英文摘要： In clinic, traditional chinese medicine for invigorating blood circulation and eliminating stasis (DRIBCAES) Occupy an important position in drugs of cure neoplasm, but previous studies had query whether it induced resistance and neoplasm metastasis. Our previous study have shown that when drug for supplement qi compatibility used with hemorheologic agent, it not only eliminate possible negative effect of DRIBCAES especially drug for disintegrating blood stasis generated, but also synergistic interaction and delay metastasis. We adopt the supplement qi and invigorate blood representative drugs in treatment of tumor, Olibanum and Astragali Radix, to observe the impact on sensibility of ovarian cancer resistance and invasion and metastasis, from the angle of cell experiment and model of transplanted tumor of ovarian cancer. we introduced LC/TOFMs and PCR to processing theory of Chinese medicine field innovatively for the first time. we discuss the influences on inhibition ratio and transport rate of transplanted tumor of ovarian cancer after WAVE3 silence, using siRNA technique to silence WAVE3 gene. Meanwhile, we detect the expression of correlation factor of resistance P-gp, MRP, BCRP, LRP and imcorrelation factor of transplant MMP-2、VEGF、FGF2、COX-2, utilizing immunohistochemisty and Real time-PCR . We used biological information database to analyze the change rule of metabolic component by means of the overall identification and taget analysis and aimed to preliminary explore the mechanism of inversing tumor drug resistance and inhibiting invasion and metastasis of Olibanum compatibility with Astragali Radix. This providing a scientific basis for enrichment and development of the compatibility theory of Traditional Chinese Medicine, guiding clinical safe and effective usage.
