| 摘 要： | 目的研究谷胱甘肽硫转移酶（Glutathione S-transferases,GSTs）家族中GSTT1、GSTM1基因多态性与急性淋巴细胞白血病患儿甲氨蝶呤（Methotrexate,MTX）血药浓度及消化道黏膜损伤的关系。方法筛选急性淋巴细胞白血病患儿98例,采用多重PCR技术分析GSTT1、GSTM1基因型,运用荧光偏振免疫分析法（FPIA）测定MTX血药浓度,同时观察患儿消化道黏膜损伤情况。结果大剂量甲氨蝶呤（3-5 g·m^-2）致消化道黏膜损伤的发生率为62.24%。相对于GSTT1基因非缺失型患儿,GSTT1基因缺失型患儿MTX 44 h血药浓度较高（P=0.003 9）。GSTM1基因型与甲氨蝶呤44 h血药浓度无明显相关。GSTT1、GSTM1两基因型均与甲氨蝶呤导致的消化道黏膜损伤无明显相关。结论 GSTT1、GSTM1基因多态性可能与MTX消化道黏膜损伤无关,尚不能作为预测HDMTX消化道黏膜损伤的遗传学标记。

| Abstract: | Aim To investigate the association between GSTT1 and GSTM1 genes polymorphisms and plasma concentration and gastric mucosal damage of high-dose methotrexate(MTX) in children with acute lymphoblastic leukemia(ALL).Methods GSTT1 and GSTM1 genotypes were analysed in 98 ALL patients with PCR.Fluorescenece polaeization immunoassay(FPIA) was used to determine the plasma concentration of MTX.The toxicity response of the patients was observed.Results Patients without GSTT1 gene had higher plasma MTX concentration t... |
