Objective To analysis the relationship between gestational age and perinatal outcomes in patients complicated with early onset severe preeclampsia.Methods Retrospective study was conducted on clinical documents of 221 patients with early onset severe preeclampsia( < 34 weeks) who delivered after 28 gestational weeks in Peking University First Hospital from July 1999 to June 2009.Patients were divided into three groups based on gestational weeks at delivery: group Ⅰ (n = 81 ) delivered at 28 -31 weeks+6,group Ⅱ (n = 78) at 32 -33 weeks+6 and group Ⅲ (n = 62) after 34 weeks.The clinical characteristics and perinatal outcomes were compared among those three groups.Results ( 1 ) Outcome of neonates:Among 221 neonates, 13 neonates lost follow-up, including 9 in group Ⅰ , 3 in group Ⅱ, 1 in group Ⅲ.The incidence of neonatal respiratory distress syndrome ( RDS ) of 26% ( 19/72 ) in group Ⅰ were significantly higher than 7% (5/75) in group Ⅱ and 10% (6/61) in group Ⅲ (P < 0.05 ).The neonatal mortality rate of (43% ,31/72) in group Ⅰ were significantly higher than 3% (2/61) in group Ⅲ and 28%(21/75) in group Ⅱ (P <0.05 ).The incidence of maternal complications showed no statistical difference among three groups.(2) Neonatal death analysis: all neonatal death were due to parents' give up, including 26%(8/31) in group Ⅰ, 67% (14/21)in group Ⅱ and 1/2 in group Ⅲ, which reached statistical difference(P<0.05).Conclusions The incidence of neonatal RDS in mother with early onset severe preeclampsia was decreased if delivered after 32 weeks, and the perinatal mortality was remarkably decreased if delivered after 34 weeks.Therefore, the perinatal survival rate in women with early onset severe preeclampsia can be improved by minimizing the impact of social factors.

Two hundred and fifty patients with subclinical hypothyroidism ( SCH) and 120 euthyroid volunteers were recruited for the study, SCH patients were stratified into 2 groups according to TSH levels(group A:TSH<10 mIU/ L; group B: TSH>10 mIU/ L). All subjects were examined for clinical characteristics, thyroid profile, lipid profile, and biomarkers of early atherosclerosis. Patients in group B received L-thyroxine replacement treatment to achieve euthyroidism. After 6 months of stable euthyroidism all measurements were repeated. SCH patients had higher levels of total cholesterol(TC), low-density lipoprotein-cholesterol(LDL-C), asymmetric dimethyl arginine (ADMA), carotid artery intima media thickness(CIMT), thromboxane B2(TXB2), and C-reactive protein(CRP) but with lower nitric oxide(NO) level compared with euthyroid subjects. Levels of TC, LDL-C, CIMT, TXB2, and ADMA decreased, and NO level increased significantly after 6 months of euthyroidism. TSH was positively correlated with TC, LDL-C, CIMT, ADMA, and TXB2; and negatively correlated with NO. Based on multivariate regression analysis, TSH was an independent influential factor of CIMT and NO. We conclude that raised TSH is an important risk factor of atherosclerosis in SCH.

Established rat models with subclinical hypothyroidism (SCH) were divided into three groups:subclinical hypothyroid(SCH),SCH treated with levothyroxine (L-T4),and control group.The L-T4 group displayed lowered total cholesterol and endothelin levels compared with the SCH group[(1.29 ±0.05 vs 2.38 ±0.55) mmol/L,(98.54 ± 32.43 vs 160.62 ±37.25) nmol/L,both P<0.05].Nitric oxide levels,left ventricular systolic pressure,and blood flow in abdominal aorta were significantly higher in the L-T4 group than those in the SCH group.The results of this study indicate that L-T4 treatment may improve endothclial dysfunction and hemodynamic changes in rats with SCH.
