摘要 目的:通过建立裸鼠人胃癌MKN-45原位移植瘤模型,观察消痰散结方对胃癌组织核转录因子(NF-κB)活性表达的影响,探讨消痰散结方抑制胃癌细胞增殖的作用机制。方法:采用OB胶粘贴法建立裸鼠人胃癌MKN-45原位移植模型,随机分成模型组,消痰散结低、中、高剂量组,5-Fu组,每组8只,采用EMSA方法检测胃癌组织NF-κB活性的表达。结果:①消痰散结方低、中、高剂量组的平均瘤重与模型组相比,有显著差异(P<0.01);②消痰散结方低、中、高剂量组NF-κB的活性表达与模型组相比逐渐降低,且呈明显的剂量依赖效应。消痰散结方低剂量组NF-κB的活性表达与模型组相比有统计学意义(P<0.05),消痰散结方中、高剂量组、5-Fu组NF-κB的活性表达与模型组相比,P<0.01,有显著统计学意义,但组间相比无统计学意义。结论:①消痰散结方有明显的抑制胃癌细胞生长的作用;②消痰散结方可能通过抑制NF-κB活性而阻断胃癌细胞增殖进程,可有效抑制胃癌发展。
