母血和脐血瘦素水平与胎儿宫内发育的相关性研究

本研究应用放射免疫分析法对72例正常分娩的产妇母、脐血中瘦素水平进行检测，目的在于探讨母体与胎儿体内的瘦素来源有无不同及与胎儿发育之间的关系。结果显示母血中瘦素水平明显高于脐血，且与孕妇体重、体重指数呈显著正相关关系，而与新生儿出生体重无明显相关性。脐血中瘦素水平与新生儿出生体重呈显著正相关关系，母、脐血中瘦素水平无相关性。说明胎儿体内的瘦素来源于其自身的分泌，且与胎儿宫内发育关系密切，而母体中的瘦素水平与胎儿发育关系不大。

Maternal Serum and Cord Blood Leptin Concentrations at Delivery in Normal Pregnancies and in Pregnancies Complicated by Intrauterine Growth Restriction

IntroductionLeptin is a polypeptide hormone, and in pregnancy, it is secreted by the placenta and maternal and fetal adipose tissues. Normal leptin production is a factor responsible for uncomplicated gestation, embryo development, and fetal growth. The study compared maternal serum and cord blood leptin concentrations at delivery in normal pregnancies and in pregnancies complicated by intrauterine growth restriction (IUGR).MethodsThe study was performed in 25 pregnant women with isolated IUGR and in 194 pregnant women without any complications. Leptin concentrations in maternal serum and in cord blood samples collected at delivery were measured by ELISA and subsequently analyzed by maternal body mass index (BMI), mode of delivery, and infant gender and birth weight. For comparative analyses of normally distributed variables, parametric tests were used, that is, the Student t test and a one-way ANOVA. The nonparametric Mann-Whitney test was used when the distribution was not normal. The Pearson correlation coefficient was calculated to assess the correlation between normally distributed variables (p < 0.05).ResultsIn pregnancies complicated by IUGR, the mean maternal serum leptin concentration at delivery was significantly higher (52.73 ± 30.49 ng/mL) than in normal pregnancies (37.17 ± 28.07 ng/mL) (p = 0.01). The mean cord blood leptin concentration in pregnancies complicated by IUGR was 7.97 ± 4.46 ng/mL and significantly lower than in normal pregnancies (14.78 ± 15.97 ng/mL) (p = 0.04). In normal pregnancies, but not in pregnancies complicated by IUGR, a statistically significant correlation was established between maternal serum leptin concentrations and maternal BMI at delivery (r = 0.22; p = 0.00). No statistically significant correlation was found between cord blood leptin concentrations and maternal BMI in either study subjects or controls. In normal pregnancies, but not in pregnancies complicated by IUGR, a strong correlation was observed between cord blood leptin concentrations and birth weight (r = 0.23; p = 0.00).ConclusionsElevated maternal blood leptin concentrations in pregnancies complicated by IUGR may indicate a significant adverse effect of elevated leptin on fetal growth. The differences in leptin concentrations, measured in maternal serum and in cord blood, between the study subjects and controls suggest that deregulated leptin levels may increase the risk of obstetric complications associated with placental insufficiency.     

妊娠期高血压疾病中血清可溶性Endoglin水平变化的研究

目的检测正常妊娠和妊娠期高血压疾病患者血清中Endoglin的水平,探究其与妊娠期高血压疾病的发病关系及意义。方法采用酶联免疫吸附双抗体夹心法（ELISA）检测44例妊娠期高血压疾病患者（妊娠期高血压疾病组,其中妊娠期高血压15例、轻度子痫前期14例、重度子痫前期15例）及16例正常晚期妊娠妇女（对照组）,22例正常中期妊娠妇女血清中Endoglin水平。结果妊娠期高血压疾病组血清Endoglin浓度为（2.86±2.15）ng/ml,正常晚期妊娠组为（1.14＋0.46）ng/ml,两组比较差异有统计学意义（P〈0.05）。妊娠期高血压、轻度子痫前期、重度子痫前期患者血清中可溶性Endoglin水平逐渐升高[分别为（1.68±0.78）ng/ml,（2.49±1.10）ng/ml,（4.44±2.94）ng/ml],各组间差异有统计学意义（P〈0.05）,且有随孕周增加而逐渐增加的趋势。正常中期妊娠组血清中Endoglin浓度为（0.83±0.32）ng/ml,与正常晚期妊娠组比较差异有统计学意义。结论血清Endoglin水平升高可能与妊娠期高血压疾病的发病及病情发展有关,并有可能成为疾病的预测指标。     

The investigation for the relationship among serum leptin,erythrocyte membrane Ca2+-ATPase activity and hypertensive disorder complicating pregnancy

Objective: To study the significance of Leptin and the activity of erythrocyte membrane Ca2+-ATPase (EMCA) in the development of hypertensive disorder complicating pregnancy. Methods: Radioimmunoassay was used to test the level of serum Leptin,and the activity of EMCA was determined chemically in 38 pregnant women with hypertensive disorder complicating pregnancy and 36 normotensive pregnant women. Results: The level of serum Leptin in hypertensive disorder complicating pregnancy(gestational hypertension: 13.76 ± 3.46 ng/ml; preeclampsia:15.76 ± 5.47 ng/ml; eclampsia: 18.32 ± 6.38 ng/ml)was significantly higher than that in normotensive pregnant women (11.33 ± 2.93 ng/ml), respectively. The average EMCA activity of patients with hypertensive disorder complicating pregnancy (gestational hypertension: 1.65 ± 0.24 μmol· pi/mg·h; preeclampsia: 1.37 ± 0.19 μmol·pi/mg·h; eclampsia:1.12 ± 0.14 μ mol·pi/mg·h) was significantly lower than that of normotensive pregnant women(1.83 ±0.38 μ mol·pi/mg·h),respectively. There was a negative correlation between the level of serum Leptin and the activity of RMCA in hypertensive disorder complicating pregnancy (r = -0.63). Conclusion: Inhibition of EMCA activity of erythrocyte in hypertensive disorder complicating pregnancy may increase cytoplasmic free calcium, which contributes to the development of hypertensive disorder complicating pregnancy. The negative correlation between the level of serum Leptin and the activity of EMCA, also suggested that serum Leptin and the activity of EMCA may play a role in the development of hypertensive disorder complicating pregnancy.

Fetal responses during placental malaria modify the risk of low birth weight

Inflammation during placental malaria (PM) is associated with low birth weight (LBW), especially during the first pregnancy, but the relative contribution of maternal or fetal factors that mediate this effect remains unclear and the role of gamma interferon (IFN-gamma) has been controversial. We examined the relationship of maternal and cord plasma levels of IFN-gamma, tumor necrosis factor alpha, interleukin-10, ferritin, and leptin to birth weight for Tanzanian women delivering in an area where there is a high rate of malaria transmission. The placental levels of inflammatory cytokines, including IFN-gamma, increased significantly during PM in primigravid and multigravid women but not in secundigravid women. PM also increased maternal peripheral levels of all inflammatory markers except IFN-gamma but had strikingly little effect on cord levels of these proteins. In a multivariate analysis, placental IFN-gamma was negatively associated (P = 0.01) and cord ferritin was positively associated (P < 0.0001) with birth weight in infected (PM-positive [PM+]) first-time mothers. This relationship was not observed in other mothers, consistent with the epidemiology of PM and disease. Cord leptin had a strong positive relationship with birth weight in offspring of PM-negative women (P = 0.02 to P < 0.0001) but not in offspring of PM+ women (all differences were not significant) in the three gravidity groups. The results confirmed that placental IFN-gamma is related to LBW due to PM during first pregnancies and suggest that fetal ferritin plays a protective role. Because fetal cells are a source of placental IFN-gamma and cord ferritin, the fetal response to PM may modify the risk of LBW.
