摘要

julie E. Bauman, chu - hsieh Hsu, Sara Centuori, Jose Guillen-Rodriguez, Linda Garland, Emily Ho, Lisa Bengtson, Malgorzata Wojtowicz, Eva Szabo, H-H Sherry cho温介绍:多吃十字花科蔬菜可以降低患烟草相关癌症的风险。十字花科植物富含植物化学物质葡萄糖苷(GR),经黑芥子酶水解成其生物活性形式萝卜硫素(SF)。SF上调抗氧化反应元件中的NRF2转录因子和下游靶基因。由于相对于成熟植物,GR主要集中在西兰花种子中,因此西兰花种子制剂(BSP)作为化学预防剂正在开发中。BSP增加了中国启东包括苯在内的空气污染物的解毒。方法:我们在健康吸烟者(≥20包年)中进行了一项随机交叉试验,评估由西兰花籽粉和西兰花芽提取物组成的BSP Avmacol片对苯和其他烟草致癌物的解毒作用。每个受试者接受低剂量和高剂量BSP治疗(每天70和140 GR当量,持续2周),通过2周的洗脱期分开,随机分为低-高和高-低顺序。主要终点是苯的解毒,通过尿中苯的硫化氢代谢物(s -苯基硫化氢,SPMA)的排泄变化来测量。次要终点包括致癌物丙烯醛和巴豆醛的解毒作用,以及通过尿中SF代谢物评估SF的生物利用度。结果:49名受试者于2018年2月- 2019年11月随机纳入:女性26名,平均年龄56.3岁。治疗相关不良事件(AE)为胃肠道;最常见的是1-2级腹胀/痉挛/腹痛(11;22%), 1级腹泻(11;22%), 1级肠胃胀气(10;20%)。没有观察到≥3级AE。一名受试者因无关AE退出。BSP和生物标志物测量的依从性为98%。主要和次要终点列于表中。结论:BSP Avmacol作为SF代谢物具有生物利用性,可显著提高重度吸烟者苯和丙烯醛的急性解毒产物。引用格式:Julie E.
