Exencephaly in autosomal dominant brachydactyly syndrome

Exencephaly was diagnosed at 17 weeks in a 27-year-old primigravida with abnormalities of the hands and a family history suggestive of autosomal dominant brachydactyly and clinodactyly. In this family there was also a history of ‘anencephaly’. To our knowledge, this is the first report on the association of exencephaly and autosomal dominant brachydactyly. As the relationship between hand and cranial anomalies is well established, we suggest that this association in our case could be due to a defect in the same gene.     

郯庐断裂系统与中国东部幔源岩浆成因CO_2关系的初探

中国已发现的幔源岩浆成因CO2气藏主要分布在与郯庐断裂发育密切相关的东部伸展盆地，两者关系具体表现如下：1．中国东部幔源岩浆成因CO2气藏的空间展布与郯庐断裂保持一致；2．郯庐断裂切割深度达到上地幔；3．沿郯庐断裂岩浆活动强烈，且具幔源特点；4．中国东部伸展盆地自中、新生代以来的演化受郯庐断裂带活动影响。本文主要以郯庐断裂带为主线，结合幔源岩浆成因CO2气藏典型实例，从郯庐断裂构造环境、空间格局和演化过程对幔源岩浆成因CO2的控制作用进行初步归纳和分析。
