摘要
目的研究Turner综合征的终身高、生长激素水平、学历和性发育的变化。方法239例Turner综合征进行染色体检查,68例行生长激素激发试验,45例随访学历和性发育的情况。结果染色体核型分4组,第1组45,X,95例;第2组嵌合型64例;第3组X染色体结构畸变74例;第4组伴有Y染色体6例。终身高139.2±8.3?。生长激素完全缺乏18例,部分缺乏34例,正常16例。随访45例中,学历大部分在初中、技校和中专19例有不同程度的性发育,26例无性发育。结论Turner征患者终身高明显低于正常人群,生长激素分泌低下,学习能力降低,性发育不全。
Objective: To research change the terminal height , the level of growth hormone, sexual development and record of formal schooling in Turner syndrome (TS). Methods: Karyotyping, growth hormone provocation tests, follow - up observations of schooling record and sexual development were studied. Results: 239 TS were karyotyped in 4 groups : Ⅰ, 45, X, 95 ;Ⅱ, mosaicism , 64; Ⅲ, with various, aberrations of structure of X chromosome, 74; Ⅳ, with Y chromosome, 6. Terminal heights were 139.2 ± 8. 3cm, 68 growth hormone tests, Growth hormone deficiency 18, part of deficiency 34 and normal 16. In the follow - up survey of 45 TS, record of formal schooling were mainly junior middle school, skill school and special school. 19 had various of degree sexual development and 26 had no. Conclusion: The terminal heights of TS were marked lower than normal, Growth hormone was deficiency, learning ability decline, hypoplasia of sex gland.
