背景拉莫三嗪(Lamotrigine,LTG)是新一代抗癫痫药物(Antiepileptic drugs,AEDs),广泛用于部分性和全面性癫痫的治疗.然而先前的研究已经观察到不同个体之间LTG药代动力学的显著差异,由于临床和环境等因素,遗传易感性对这些差异起到重要作用.研究发现单核苷酸多态性(Single nucleotidepolymorphisms,SNPs)如UGT1A4和UGT2 b.可能影响LTG的血药水平,多态转运蛋白如P-糖蛋白(P-glycoprotein,P-gp,由MDR1/Ab.b.编码)、乳腺癌而耐药蛋白(b.east cancer resistance protein,b.RP,由Ab.G2编码)和多药耐受蛋白(Multi-drug resistance protein 2,MRP,由Ab.C2编码)的过表达对LTG治疗的药代动力学和生物利用度也产生影响.研究发现Ab.b. rs1128503和Ab.G2 rs2231142的基因多态性与LTG单药治疗时的血药浓度有关.然而,另一Ab.G2基因的变异(rs2231137)和Ab.C2的作用并没有研究报道.作为流入转运体亚家族的有机阳离子转运体(Organic cation transporters,OCTs)在阳离子药物的分布和分泌中起到重要作用.肝细胞核因子4α(Hepatocyte nuclear factor 4 alpha,HNF4α)是肝组织内调节肝细胞发育和分化的因子,在人类和老鼠的肝脏中与多种基因启动子直接相连.有报道表明HNF4α rs2071197可能与LTG血药浓度相关,然而另一个SNP(HNF4α rs3212183)对于LTG血药浓度的作用并不甚清楚.

50多年来人们一直将b.astocystis hominis误认为是一种无害的肠道酵母菌,因为它非常象酵母菌,例如在新鲜的湿封片中外表闪光、通常无运动迹象、在未染色的标本中其核不可辨认等等。但近年来,人们巳逐渐认识到它是一种能引起肠道疾病的原虫,因为它具有原虫的生理学特征:严格的厌氧、在真菌和细菌的培养基及固体培养基表面不能生长、适宜于在37℃、pH中性的条件下生长、能摄食细菌及其它颗粒性物质、营养要求类似于其他肠道原虫等等。此外它的形态结构和超微结构方面亦符合原虫的特征。 b.h能引超人类的肠道疾病,临床症状为腹痛、恶心、呕吐、腹胀、厌食、里急后重等,但多为自限性的,偶然可引起猴类的致死性感染。本病的治疗可用吐根素、灭滴灵、痢特灵、碘氯羟喹等。已知b.h是引起人类肠道疾病的一个病因,但它的传播、致病机理、治疗等方面的问题尚需深入探讨。
