Objective To explore the effect of advanced glycation end product(AGE) in serum of maternal rats with gestational diabetes mellitus (GDM) on the heart development of their offsprings. Methods Fifty-four SD rats were randomly assigned into control group (n= 24) and GDM group (n=30) which were established by administration of streptozotocin intra-abdominally. On the gestational age of 13, 16, 19 days, all rats underwent hysterectomy to obtain the fetal heart tissues. Serum level of AGE and blood glucose level of maternal rats were tested. The expression of receptor AGE (RAGE) in fetal cardiac tissue were detected by immunohistoehemistry. Results The incidence of fetal heart defect in GDM group was significantly higher than the control group at each time point (P<0.01). Rats in GDM group had higher blood glucose level at each time point (P<0.01). The AGE levels of GDM group on gestational age of 13, 16 and 19 day [(5.72±0.68) U/mgpr, (7.31±0.29) U/mgpr and (7.77±0.39) U/mgpr] were significantly higher than those of the control group [(4.45±0.27) U/mgpr, (4.71±0. 35) U/mgpr and (4. 37±0. 44) U/rngpr] (t=6. 142, 16. 295, 0. 399,P<0. 01). The number of heart malformation in fetal rats (r=0.994,P=0. 000) and blood glucose (r=0. 717,P=0. 000) had the positive relationship with the maternal serum AGE level. The expression of RAGE in fetal heart was positively related with the number of fetal heart malformation (r= 0. 638,P= 0. 004). Conclusions The increased maternal serum AGE level in GDM rats may be an important factor in fetal heart dysplasia.

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.
