METHODS: We recruited 42 ICP and 32 normal pregnancy women in this study. The maternal blood, fetal blood and amniotic fluid TBA level were detected using a circulating enzymatic method. Umbilical blood pulmonary surfactant protein A(SP-A) was evaluated with enzyme-linked immunosorbent assay. High performance liquid chromatography was used for the determination of phosphatidyl choline(PC), phosphatidyl inositol(PI), lysolecithin(LPC) and sphingomyelin(SM). Amniotic fluid lamellar body was counted with a fully automatic blood cell counter. Fetal lung area and fetal body weight were calculated from data obtained with an iu22 color supersonic diagnostic set. Clinical information of a nonstress test, amniotic fluid properties and neonatal Apgar score, and birth weight were recorded for review. RESULTS: The TBA level in maternal blood, fetal blood and amniotic fluid in the ICP group were significantly higher than that in the control group(maternal blood: 34.11 ± 6.75 mmol/L vs 4.55 ± 1.72 mmol/L, P < 0.05; fetal blood: 11.9 ± 2.23 mmol/L vs 3.52 ± 1.56 mmol/L, P < 0.05; amniotic fluid: 3.89 ± 1.99 mmol/L vs 1.43 ± 1.14 mmol/L, P < 0.05). Amniotic fluid PC and PI in the ICP group were significantly lower than that in the control group(PC: 65.71 ± 7.23 μg/m L vs 69.70 ± 6.68 μg/m L, P < 0.05; PI: 3.87 ± 0.65 μg/m L vs 4.28 ± 0.74 μg/m L, P < 0.05). PC/LPC ratio of the ICP group was lower than that of the control group(14.40 ± 3.14 vs 16.90 ± 2.52, P < 0.05). Amniotic LB in the ICP group was significantly lower than that of the control group((74.13 ± 4.37) × 109/L vs(103.0 ± 26.82) × 109/L, P < 0.05). Fetal umbilical blood SP-A level in the ICP group was significantly higher than that of the control group(30.26 ± 7.01 ng/m L vs 22.63 ± 7.42 ng/m L, P < 0.05). Fetal lung area/body weight ratio of the ICP group was significantly lower than that of the control group(5.76 ± 0.63 cm2/kg vs 6.89 ± 0.48 cm2/kg, P < 0.05). In the ICP group, umbilical cord blood TBA concentration was positively correlated to the maternal blood TBA concentration(r = 0.746, P < 0.05) and umbilical blood SP-A(r = 0.422, P < 0.05), but it was negatively correlated to the amniotic fluid lamellar corpuscle(r = 0.810, P < 0.05) and fetal lung area/body weight ratio(r = 0.769, P < 0.05). Furthermore, umbilical blood TBA showed a negative correlation to PC, SM and PI(r pc = 0.536, r sm = 0.438, r pi = 0.387 respectively, P < 0.05). The neonatal asphyxia, neonatal respiratory distress syndrome, fetal distress and perinatal death rates in the ICP group are higher than that of theCONCLUSION: ICP has higher TBA in maternal and fetal blood and amniotic fluid. The high concentration of TBA may affect fetal pulmonary surfactant production and fetal lung maturation.展开更多
