N/A Objective : To investigate the mechanisms involved in the mRNA expressions of hCG, LH/CG receptor and in hormone secretion in the trophoblast of normal and abnormal early pregnancy. Methods : hCG, free β-hCG, and progesterone concentrations were measured in serum and the mRNA expressions of α,β-hCG and LH/CG receptor were measured in the placental trophoblast of 22 spontaneous abortion patients (spontaneous abortion group), 20 normal pregnancy women (normal pregnancy group) and 6 hydatidiform mole patients (hydatidiform mole group). Results : 1. Mean values of serum hCG and free β-hCG concentrations were the lowest in spontaneous abortion group (46343.63±40404.18 mIU/ml, p<0.001; 31.34±61.57 mIU/ml, p<0.01 respectively) among the three groups. Mean progesterone concentration was the lowest in spontaneous abortion group (11.84±7.60 ng/ml, p<0.01), too. 2. The expression levels of α,β-hCG were the highest in spontaneous abortion group (4.64±5.47, p=0.015; 4.57±4.42 p=0.002 respectively). The expression levels of LH/CG receptor were not different statistically among the three groups and they were high at the 5th week of gestation, reaching nadir at the 10th week of gestation when the concentrations of serum hCG showed peak values in normal pregnancy group. 3. The correlations between serum hCG and progesterone concentrations were positive in both spontaneous abortion (r=0.827, p<0.001) and normal pregnancy (r=0.438, p=0.054) group. Though they were not significant statistically, the correlations between progesterone concentrations and the levels of α,β-hCG expressions were negative in both spontaneous abortion (r=-0.237, p=0.289; r=-0.211, p=0.347) and normal pregnancy (r=-0.270, p=0.250; r=-0.235, p=0.318) group. In hydatidiform mole group, the correlation between progesterone concentrations and the levels of β-hCG expression was positive (r=0.968, p=0.002). Conclusion : Our results suggest that the mechanisms involved in the secretion of hCG, progesterone and the expression of α,β-hCG, LH/CG receptor be normal in spontaneous abortion as in normal pregnancy and in the both groups, hCG stimulate the secretion of progesterone by autocrine function and control the secretion of itself, through the suppression of the expressions of α,β-hCG and LH/CG receptors. So the cause of spontaneous abortion in early pregnancy may be not placental dysfunction but the defect of embryo itself with poor placental growth.

N/A A retrospective study was conducted to evaluate the clinical outcomes of midtrimester emergency cervical cerclage in patients with painless cervical dilatation with/without prolapsed amniotic sac, including cases of no previous history of cervical incompetence. 10 patients including 1 twin pregnancy were teviewed for study, All had received emergency cervical cerclage with Macdonald operation or Shirodka operation at 18 to 31 weeksgestation. The procedures were carried out without serious complication except for one patient who had received re-operation 3 days after Macdonald operation because of re-protrusion of amniotic sae. The mean procedure to delivery internal was 8.9+5.3 (range 1 to 17) weeks. The mean gestational age at delivery was 32.4+5.6 (range 22 to 39+6) weeks for the entire group, 36.1+2.6 (range 32+4 to 39+6) weeks for the 6 who achived viability, and 27.6+5.0 (range 22 to 29+4) weeks for the 3 who died during the neonatal period. 1 died during gestation and was delivered at 33+6 weeksgestation. The mean birthweight was 2181.6+971.6 (range 498 to 3500)g for the entire group, and 2712.9+ 571.5 (range 1860 to 3500)g for the 7 infants who lived until after neonatal period. The total survival rate for 11 babies was 64%. This study demonstrates that midtrimester emergency cervical cerclage for the patients who have dilated cervix with/without prolapsed amniotic sac is valuable method to try in the cases predicted they would lost the baby with conservative treatment only.
