Using the spectral subtraction technique, we analyzed our spectroscopic data and calculated the equiva- lent widths of excess emission from several indicators of chromospheric activity （Na I D1, D2, Hoz and Ca II infrared triplet lines）. All our results using chromospheric activ- ity indicators confirmed the previous findings. In addition, the maximum amplitudes of chromospheric rotational modulation and the ratio of EW8542/EW8498 were found to rise with increasing v sin i velocity.展开更多
报告以脑积水起病的晚发型戊二酸血症1型(glutaric acidemia type 1,GA1)1例。患者女性,21岁,以急性脑积水为主要临床表现,头颅MRI示脑内大范围脑白质、双侧基底节区及小脑半球蚓部异常信号,双侧脑室扩张,双侧颞极蛛网膜囊肿。血尿有机...报告以脑积水起病的晚发型戊二酸血症1型(glutaric acidemia type 1,GA1)1例。患者女性,21岁,以急性脑积水为主要临床表现,头颅MRI示脑内大范围脑白质、双侧基底节区及小脑半球蚓部异常信号,双侧脑室扩张,双侧颞极蛛网膜囊肿。血尿有机酸分析检出大量戊二酸和3-羟基戊二酸,GCDH基因检测发现为复合杂合性突变(S119L和R355H),确诊为戊二酸血症1型,给予相关治疗后,症状缓解。可见临床上如遇上难以解释的脑积水,头部MRI示典型对称性病灶,包括小脑损害,应进行血尿有机酸筛查以除外代谢性疾病。展开更多
