妊娠合并甲状腺功能减退症或亚临床甲状腺功能减退症77例临床分析

Objective To investigate the maternal and fetal outcomes of pregnant women with hypothyroidism or subclinical hypothyroidism. Methods From Jan. 2005 to Mar. 2008, clinical records of 77 women with hypothyroidism (n=57) or subclinical hypothyroidism (n = 20) during pregnancy who delivered at Peking Union Medical College Hospital were reviewed. The basic information, maternal complications and neonatal outcomes of the patients were compared with 79 healthy women who delivered during the same period. Results The prevalence of maternal hypothyroidism during the study period was 0.74% ,and that of maternal subclinical hypothyroidism was 0.26%. The mean neonatal birth weight of women with hypothyroidism was lower than that of the control [(3191.8±659.47 g) vs (3301.9±423. 1 g), P<0.05], the incidence of abnormal glucose metabolism was higher (24.6% vs 11.4% ,P<0.05), and small for gestational age infants were more common than in the control group (12. 3% vs 2. 5%, P<0. 05). The maternal and fetal outcomes of women with subclinical hypothyroidism during pregnancy showed no difference compared with the control. Conclusions Early screening for the high risk women and appropriate management are important to improve the neonatal and fetal outcomes of women with hypothyroidism and subclinical hypothyroidism during pregnancy.     

高通量基因测序技术在自然流产遗传学分析中的应用

目的初步探讨高通量测序技术在自然流产绒毛遗传学分析准确性和异常核型检出率中的作用。方法采用高通量测序和生物信息分析技术,选取常规染色体核型分析结果为46,XY的自然流产绒毛样本进行检测,比较两种检测结果的一致性及差异。结果 (1)常规染色体核型分析技术:14例样本染色体核型分析结果均为46,XY。(2)高通量测序技术:14例样本染色体核型均为46,XY,有拷贝数变异(CNV)改变的占43%(6/14),能检测到250kb~16.5M染色体片段的改变。(3)通过两种检测方法的比较,发现高通量测序技术检测时间短,对染色体结构异常有更高的检出率。结论高通量测序技术更敏感、高效,具有更高的染色体异常检出率。可作为常规染色体核型分析的补充检测手段。
