    • 摘要: 胃肠道间质瘤(GISTs)是最常见的消化道恶性肿瘤之一,且对放化疗皆不敏感.酪氨酸激酶抑制剂(TKIs)作为特效药应用于临床治疗后取得了显著疗效,但随之而来的耐药性限制了其临床应用.随着相关机制研究不断深入,新颖的治疗药物也层出不穷.可见,关于胃肠道间质发病机制的基础研究对于发现治疗新方法至关重要.目前至少有3种模型被广泛应用于肿瘤发病机制的基础研究实验,即同源耐药/敏感细胞株模型,肿瘤移植小鼠模型,还有人体肿瘤标本.本文将回顾有关胃肠道间质瘤耐药机制研究方法的文献,对相关研究方法和发现的主要耐药机制进行系统综述.%gastrointestinal stromal tumors (GISTs) are one of the most common malignant tumors of digestive tract,and are resistant to cytotoxic radiotherapy and chemotherapy.Tyrosine kinase inhibitors (TKIs) have been used as a miracle drug for clinical treatment.However,the drug resistance has limited its clinical application.With the continuous deepening understanding of the relevant mechanisms,novel therapeutic agents are emerging.Therefore,fundamental studies on the pathogenesis of gastrointestinal stromal tumor are essential for the discovery of novel therapeutic approaches.At present,there are at least three models which are widely applied in the basic research of the pathogenesis of tumor,which are the homologous resistant/sensitive cell line model,the tumor transplanted mouse model,and the human tumor specimen.In this paper,we review the literature on the research methods of gastrointestinal stromal tumor resistance mechanism,and summarize the related research methods and the main mechanisms of drug resistance.

    • 摘要: 目的:汉黄芩苷、汉黄芩素、黄芩苷及黄芩素是黄芩的主要成分.对前三种黄酮的抗癌活性文献有不同的报导.方法:本研究比较了4种黄酮在相同浓度下对4个肿瘤细胞株24 h及48 h存活率的影响.结果:实验结果显示,汉黄芩素对4种细胞株都有明显的抑制作用,48 h半抑制浓度分别为97.9 μM(肺腺癌A549)、15.3 μM(子宫颈癌HeLa)、147 μM(肝细胞癌HepG2)及104 μM(乳腺癌MCF-7).其相应的糖化物,汉黄芩苷对4种细胞均未显示抑制.黄芩素抑制HeLa细胞,而糖化的黄芩苷抑制HepG2,且对MCF-7显示刺激作用.结论:以上结果显示,汉黄芩素在4种主要黄芩黄酮中具有最强的抑制肿瘤细胞生长效能,而其他3种黄酮的抗肿瘤作用并不一致,黄芩苷甚至促进个别肿瘤细胞株的生长.因此,黄酮抗癌作用的研究及可能的临床应用更应在单体水平进行.%Wogonoside,wogonin,baicalin and baicalein are major chemical constituents of S.baicalensis.Baicalin,baicalein and wogonin have been reported previously to exert anti-cancer effects.The present study compared the anti-cancer effects of the four flavonoids individually towards four human cancer cell lines after 24-and 48-hour treatment based on cell viability assay.As a result,wogonin inhibited the growth of the four cell lines.The IC50 values after 48 hours of incubation were 97.9 μM for A549 lung adenocarcinoma cells,while 15.3 μM for HeLa cervical carcinoma cells,147 μM for HepG2 hepatocellular carcinoma cells and 104 μM for MCF-7 breast adenocarcinoma cells.In contrast,wogonoside,the glycoside of wogonin,showed no inhibitory effect against any one of the four cell lines.Baicalein inhibited the growth of HeLa cells,while baicalin inhibited the growth of HepG2 cells,both with higher IC50 values and less potent than wogonin.These findings established wogonin as the most active anti-cancer agent among the four major flavonoids of S.baicalensis.Since baicalin,the most abundant flavonoid in the herb,was found to enhance the growth of MCF-7 cells.Clinical applications of ingredients from S.baicalensis to the treatment of cancer should be carried out with purified compounds.
