Androgen insensitivity syndrome （AIS）, an X-linked recessive genetic disorder of sex development, is caused by mutations in the androgen receptor （AR） gene, and is characterized by partial or complete inability of specific tissues to respond to androgens in individuals with the 46,XY karyotype. This study aimed to investigate AR gene mutations and to characterize genotype-phenotype correlations. Ten patients from unrelated families, aged 2-31 years, were recruited in the study. Based on karyotype, altered hormone profile, and clinical manifestations, nine patients were preliminarily diagnosed with complete AIS and one with partial AIS. genetic analysis of AR gene revealed the existence of 10 different mutations, of which five were novel （c.2112 C〉G[***4R], c.2290T〉A[p.Y764N], c.2626C〉T[p.Q876X], c.933dupC[p.K313Qfs＊28], and c.1067delC[p.A356Efs＊123]）; the other five were previously reported （c.1789G〉A[p.A597T], c.2566C〉T[p.R856C], c.2668G〉A[p.V890M], c.2679C〉T[p.P893L], and c.1605C〉G[p.Y535X]）. Regarding the distribution of these mutations, 60.0% were clustered in the ligand-binding domain of AR gene. Exons 1 and 8 of AR gene each accounted for 30.0% （3/10） of all mutations. Most of the truncation mutations were in exon 1 and missense mutations were mainly located in exons 4-8. Our study expands the spectrum of AR gene mutations and confirms the usefulness of AR gene sequencing to support a diagnosis of AIS and to enable prenatal or antenatal screening.

以黄河三角洲垦利县为研究靶区,采用多时相陆地卫星TM数据,对耕地的动态变化及其驱动力进行了系统研究。采用人机交互式的目视解译和人工修正方法提取耕地信息,以分类后比较法和历史土地利用专题图支持下的目视检测方法进行耕地变化信息的获取。在此基础上,建立了基于TM数字图像的耕地变化及其自然和人为驱动力指标,通过耕地变化及其相关因素分析、空间一致性分析等,确定了耕地变化的驱动因子。结果表明:从1987年至1998年,垦利县耕地面积减少了5321.8hm2,平均每年减少483.8hm2,耕地的减少主要分布于中部稻田区和东北部旱区。不良的人为活动、土壤盐渍化和水源的匮乏是该区耕地动态变化的驱动因子。
