Transarterial chemoembolization (TACE) is the standard treatment for intermediate stage hepatocellular carcinoma (HCC). Radiomics, which can mine high-throughput quantitative image features from medical imaging images, can noninvasively evaluate the lesions and is important for predicting the therapeutic effect of TACE in hepatocellular carcinoma. This article reviews the ap-plication of radiomics in TACE treatment of hepatocellular carcinoma in recent years.展开更多
快速准确的害虫种类识别是有效筛选天敌昆虫开展靶向性生物防控的关键。入侵种西花蓟马Frankliniella occidentalis与本地种花蓟马F.intonsa常同域同期同种寄主上发生,因体型小、形态相似,难以快速准确鉴定。本研究以mt DNA COI与r DNA ...快速准确的害虫种类识别是有效筛选天敌昆虫开展靶向性生物防控的关键。入侵种西花蓟马Frankliniella occidentalis与本地种花蓟马F.intonsa常同域同期同种寄主上发生,因体型小、形态相似,难以快速准确鉴定。本研究以mt DNA COI与r DNA ITS2基因为标记对我国10个采样点的西花蓟马和花蓟马开展分子鉴定研究。结果显示,当以COI或ITS2基因为靶标时,西花蓟马与花蓟马间的平均遗传距离分别为0.221和0.113,是种内遗传距离的22.1和18.8倍,且种内、种间遗传距离间无重叠,并在系统发育树上聚为独立的分支,表明2种基因均可准确区分西花蓟马和花蓟马。此外,基于COI基因构建的系统发育树,西花蓟马的各单倍型聚为了2个亚分支,并分别对应温室品系和羽扇豆品系,表明COI基因还可用于西花蓟马品系的识别鉴定。研究结果对近缘种花蓟马的快速鉴定、专食性天敌昆虫的筛选,及其生防效果评价具有重要意义。展开更多
