The objective of this study was to investigate the relationship between preeclampsia and iodine levels and magnesium concentration in the blood of subjects in the northeast Anatolia region where iodine deficiency is common. Blood specimens were obtained from 24 preeclamptic and 16 healthy pregnant women. Iodine levels in blood were determined by the Foss method based on the Sandell–Kolthoff reaction. Serum protein-bound iodine (PBI) levels and magnesium concentration in maternal blood were lower in patients with severe preeclampsia compared to normal pregnant women (8.46?±?1.22 vs. 11.46?±?1.71 μg/dL, p?<?0.001, 1.63?±?0.05 vs. 1.86?±?0.05 mg/dL, p?<?0.001, respectively). Serum PBI levels and magnesium concentration in umbilical cord blood were higher in patients with severe preeclampsia than in normal pregnant women (8.84?±?1.9 vs. 7.33?±?1.07 μg/dL, p?<?0.05, 2.48?±?0.03 vs. 2.02?±?0.01 mg/dL, p?<?0.001, respectively). There was a positive correlation between the serum PBI levels in maternal blood and magnesium concentration in maternal blood in patients with severe preeclampsia (r?=?0.41, p?<?0.05). Thus, iodine may be one factor contributing to the pathophysiology of preeclampsia. Iodine supplementation may be effective therapy in preeclamptic in pregnant women. 相似文献

Our aim was to investigate parameters of iron and copper status and oxidative stress and antioxidant function in women with healthy pregnancy, mild and severe preeclampsia with a view to exploring the possible contribution of these parameters to the aetiology. Thirty healthy, 30 mild preeclamptic and 30 severe preeclamptic pregnant women were included. Serum and placental lipid peroxides, and serum vitamin E and total carotene levels were measured by colorimetric assay. Cholesterol, copper, iron, total iron binding capacity (TIBC), ceruloplasmin and transferrin concentrations were measured by commercially available procedures. Data were analysed statistically using one-way analysis of variance and Pearson correlation test. Logistic regression procedures were used to calculate odds ratios. Lipid peroxides in serum and placental tissue, and iron, copper and ceruloplasmin levels in serum were significantly increased, and transferrin, TIBC, vitamin E/total cholesterol and total carotene/total cholesterol ratios in serum were significantly decreased especially in women with severe preeclampsia. Significant correlations were detected between serum iron and lipid peroxides in serum and placental tissue and between serum iron and vitamin E/total cholesterol in severe preeclamptic pregnancy. Furthermore, there were significant correlations between serum malondialdehyde and ceruloplasmin and vitamin E/total cholesterol in women with severe preeclampsia, and changes in serum and placental lipid peroxides and serum iron concentrations were significantly associated with preeclampsia. In conclusion, ischaemic placental tissue may be a primary source of potentially toxic iron in preeclampsia and the released iron species may contribute to the aetiology and would exacerbate lipid peroxidation and endothelial cell injury, which may be abated by antioxidant supplementation. 相似文献

Preeclampsia is a common (approximately 7% of all pregnancies) disorder of pregnancy in which the normal hemodynamic response to pregnancy is compromised. Despite many years of intensive research, the pathogenesis of preeclampsia is still not fully understood. The objective of the present study was to investigate the levels of coenzyme Q(10) (CoQ(10)) in placental tissue compared to maternal and umbilical cord levels both during normal pregnancy and in those complicated with preeclampsia. Pregnant women (n = 30) and women with preeclampsia (n = 30) were included. Maternal, newborn cord blood levels and placental content of coenzyme Q(10) were measured by high performance liquid chromatography (HPLC). Plasma coenzyme Q(10) levels were significantly higher in normal pregnant women than in women with preeclampsia. CoQ(10) content in placenta from women with preeclampsia (mean 0.28 SEM 0.11 nmol/mg protein) was significantly higher compared to normal pregnancy (mean 0.09 SEM 0.01 nmol/mg protein; p = 0.05). Levels of CoQ(10) in cord blood from normal pregnant women (mean 0.30 SEM 0.05 micromol/l) were significantly lower than in preeclamptic women (mean 4.03 SEM 2.38 micromol/l). In conclusion, these data indicate a possible involvement of CoQ(10) in preeclampsia that might bear deep physiopathological significance and deserve to be further elucidated. 相似文献

Preeclampsia is a high-prevalence systemic pregnancy disorder associated with maternal and foetal mortality. Its pathogenesis
is unknown, but it is thought that oxidative stress and endothelial dysfunction may play a fundamental role. Von Willebrand
factor (vWF), a marker of endothelial cell injury, can be found in different cells and zones of the placenta. To determine
the differential immunoexpression of vWF at different tissue types of preeclamptic placenta and endothelial dysfunction markers
at maternal serum of preeclamptic pregnancies. A case–control study was performed on a population of pregnant women with preeclampsia
(n = 14), and normal pregnancies (n = 8). Placental and blood plasma samples were withdrawn at delivery. Immunohistochemical
vWF expression in the placental tissue was determined. Endothelial dysfunction was assessed through plasminogen activator
inhibitor (PAI) 1 and 2 ratio and vWF concentration in maternal plasma. P values less than 0.05 were considered statistically significant. Preeclamptic women showed increased plasma PAI-1/PAI-2 ratio
(P < 0.05). There was diminished placental vWF expression in syncytiotrophoblast and increased in the intervillous space of
preeclamptic placentas (P < 0.05). No significant differences in vWF expression were found in the villous endothelium and stroma, but it was significantly
higher in maternal plasma (P < 0.05). In preeclampsia occurs endothelial damage and placental cell injury. Cell damage in syncytiotrophoblast that occurs
in preeclampsia could liberate vWF from syncytiotrophoblast to the placental intervillous space, and this may have pathogenic
implications. 相似文献

Preeclampsia complicates 2–8 % of all pregnancies and it is one of the leading causes of maternal mortality and pre-term delivery in the world. Unfortunately, there is scarcity of document discussing the circulating level of several essential trace elements in preeclampsia patients in Bangladesh. The present study was designed to evaluate the serum concentration of four trace elements, namely zinc, copper, manganese, and iron, in preeclamptic pregnant women. The study was conducted as a case–control study with 50 preeclamptic pregnant women as cases and 58 normotensive pregnant women as controls. Obstetric, anthropometric, and clinical data were collected at routine obstetric visits. Serum trace elements were determined by flame atomic absorption spectroscopy. Independent sample t test and Pearson’s correlation test were done for the statistical analysis using the statistical software package SPSS, version 16.0 (SPSS Inc., Chicago, IL). We observed significant differences for gestational age, body mass index, and systolic and diastolic blood pressure between patient and control groups (p?<?0.05). Analysis of serum trace elements explored significantly lower level of all the four elements in preeclampsia patients in comparison to the control group (p?<?0.05). Pearson’s correlation analysis explored that the correlation between serum level of different trace elements was statistically insignificant (p?>?0.05) except the correlation between zinc and iron in preeclampsia patients (p?<?0.05). Establishment of inter-element relationship strongly supports that there was a disturbance in the element homeostasis in patient with preeclampsia. In conclusion, our study suggests that preeclampsia patients have considerably lower level of serum zinc, copper, manganese, and iron compared to the healthy pregnant women. 相似文献

BackgroundPreeclampsia is a pregnancy-specific disorder characterised by an inappropriate maternal inflammatory response during pregnancy. High mobility group box 1 (HMGB1) was originally characterised as a nuclear protein but when released into the extracellular environment following necrotic cell death, it is proinflammatory. HMGB1 is expressed in the syncytiotrophoblast of human placenta. Higher levels of uric acid are reported in preeclampsia. The aim of this study was to investigate whether the expression of HMGB1differed between early onset and late onset preeclampsia or severe and mild preeclampsia and whether its expression correlated with the levels of uric acid.Methods74 preeclamptic placentae and 110 normotensive placentae were included in this study. The levels of uric acid in women with preeclampsia were measured. The expression of HMGB1 in preeclamptic placentae or in first trimester and term placentae that had been treated with uric acid was measured.ResultsHMGB1 was expressed predominantly in the syncytiotrophoblast of the placenta and the expression of HMGB1 in the cytoplasm of the syncytiotrophoblast was significantly increased in both severe preeclampsia and early onset preeclampsia compared to normotensive pregnancies. The circulating levels of uric acid were significantly increased in preeclampsia and correlated with the expression of HMGB1. Increased levels of HMGB1 were significantly correlated with the severity and the time of onset of preeclampsia, but pathologic levels of uric acid did not increase the expression of HMGB1.ConclusionOur data provides a better understanding of the function of HMGB1, a danger molecule in the pathogenesis of preeclampsia. 相似文献

Preeclampsia is a pregnancy-specific syndrome and a major cause of maternal mortality. The pathophysiology of preeclampsia is unknown, and no proteome analysis of preeclampsia has been reported. We sought to identify proteins associated with preeclampsia using a proteomic technique and performed two-dimensional electrophoresis (2-DE) on sera from six patients with preeclampsia and six normal pregnant women, followed by comparison of the SYPRO Ruby-stained 2-DE profiles. A group of overexpressed spots was identified in the limited study set. Overexpressed spots were identified as clusterin by matrix-assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI-TOF-MS) followed by peptide mass fingerprinting, a protein database search, and Western blot analysis. Additionally, sera of 80 preeclamptic women and 80 normal pregnant women were processed by immunoassay methods to confirm changes in clusterin concentrations quantitatively. Immunoassays showed that clusterin levels in the 80 preeclamptic women were significantly higher than those in the 80 controls (mean +/- SD; 1.62 +/- 0.46 times reference level in preeclamptic women vs. 1.30 +/- 0.46 times reference level in controls, P < 0.001). Proteomic analysis of serum proteins is a promising tool for studying preeclampsia pathophysiology and identifying proteins associated with preeclampsia. 相似文献

Background
Meteorin (METRN) is a recently described neutrophic factor with angiogenic properties. This is a nested case-control study in a longitudinal cohort study that describes the serum profile of METRN during different periods of gestation in healthy and preeclamptic pregnant women. Moreover, we explore the possible application of METRN as a biomarker.Methods and Findings
Serum METRN was measured by ELISA in a longitudinal prospective cohort study in 37 healthy pregnant women, 16 mild preeclamptic women, and 20 healthy non-pregnant women during the menstrual cycle with the aim of assessing serum METRN levels and its correlations with other metabolic parameters. Immunostaining for METRN protein was performed in placenta. A multivariate logistic regression model was proposed and a classifier model was formulated for predicting preeclampsia in early and middle pregnancy. The performance in classification was evaluated using measures such as sensitivity, specificity, and the receiver operating characteristic (ROC) curve. In healthy pregnant women, serum METRN levels were significantly elevated in early pregnancy compared to middle and late pregnancy. METRN levels are significantly lower only in early pregnancy in preeclamptic women when compared to healthy pregnant women. Decision trees that did not include METRN levels in the first trimester had a reduced sensitivity of 56% in the detection of preeclamptic women, compared to a sensitivity of 69% when METRN was included.Conclusions
The joint measurements of circulating METRN levels in the first trimester and systolic blood pressure and weight in the second trimester significantly increase the probabilities of predicting preeclampsia. 相似文献10.

Our earlier studies, in preeclamptic women have shown altered levels of long chain polyunsaturated fatty acids (LCPUFA), essential constituents of the cell membrane lipids responsible for membrane stability as one of the key factors contributing to the pathophysiology of preeclampsia. We have also reported elevated levels of sFlt-1 in preeclampsia. The present study examines the levels of LCPUFA and their association with sFlt-1 levels in 69 pre-eclamptic women and 40 normotensive women. DHA and omega 3 fatty acid levels were lower (p<0.001) while arachidonic acid and omega 6 fatty acid levels were higher (p<0.05) in preeclamptic women as compared to normotensive women. Maternal plasma sFlt-1 levels were higher (p<0.05) in preeclamptic women and were negatively associated with DHA (p=0.008) and omega 3 fatty acids concentrations (p=0.031). Our results suggest that altered placental LCPUFA may result in altered membrane lipid fatty acid composition leading to increased release of sFlt-1 in circulation. 相似文献

Preeclampsia, which is caused by multiple factors, still remains one of the most serious complications of pregnancy. This study was designed to determine cadmium levels in women with preeclampsia compared to those of normotensive women. In this case-control study, maternal blood, umbilical cord blood, and placental cadmium levels were measured by an inductively coupled plasma mass spectrometry system in 51 women presenting consecutively with preeclampsia and 51 normotensive pregnant women. Groups were matched for maternal age, parity, and gestational age. Birth outcomes were recorded, such as gestational age at delivery, birth weight, and Apgar score. Median (interquartile range [IQR]) blood cadmium concentration was 1.21 μg/L (0.76–1.84 μg/L) and 1.09 μg/L (0.72–1.31 μg/L) in women with preeclampsia and normotensive, respectively; values for placental cadmium levels of women with preeclampsia and normotensive were 3.61 μg/kg (2.19–4.37 μg/kg) and 4.28 μg/kg (3.06–5.71 μg/kg), respectively. We observed a statistically significant increase in blood and placental cadmium levels in women with preeclampsia compared to healthy pregnant women. After adjusting for pre-pregnancy body mass index, maternal age, parity, gestational age at sample collection, and maternal calcium and magnesium levels, the odds ratio of having preeclampsia in the high tertile was markedly increased (odds ratio, 7.83 [95% CI, 1.64–37.26]) compared with the low tertile. Interestingly, there was no difference in the cadmium level in umbilical cord blood between the groups. Within the preeclamptic group, higher cadmium status was significantly associated with decreased birth weight. Our study suggested that elevated cadmium level in the maternal circulation could potentially increase the risk of preeclampsia. The results also demonstrate that higher cadmium status may contribute to fetal growth restriction in preeclamptic patients. 相似文献

The aim of this study was to investigate the urine iodine concentration in women with severe preeclampsia and in healthy women
in Erzurum, Turkey. Urine specimens were obtained from 40 severe preeclampsia and 18 healthy pregnant women. Urinary iodine
levels were determined by the Foss method based on the Sandell–Kolthoff reaction. The urinary iodine level for women with
severe preeclampsia was 4.25 ± 2.7 μg/dL, lower than 20.89 ± 6.4 μg/dL of urinary iodine for healthy pregnant women (p < 0.001). Blood magnesium concentration was found to be 1.63 ± 0.05 mg/dL for women with severe preeclampsia, which is lower
than that of healthy pregnant women (1.87 ± 0.05 mg/dL; p < 0.001). There was a positive correlation between urinary iodine level and blood magnesium level in pregnant women with
preeclampsia (Pearson correlation coefficient = 0.43; p < 0.01). However, there was no correlation between urinary iodine level and blood magnesium level in healthy pregnant women.
There was no difference in thyroid hormone levels (T4, TSH, FT4) between women with severe preeclampsia and healthy pregnant
women. However, there was a difference in T3 thyroid hormone levels between women with severe preeclampsia (1.86 ± 0.4 μg/dL)
and healthy pregnant women (1.45 ± 0.3 μg/dL; p < 0.001). There was also a difference in FT3 between women with severe preeclampsia (2.77 ± 0.4 pg/mL) and healthy pregnant
women (2.41 ± 0.5 μg/dL; p < 0.01). Urinary iodine excretion is currently the most convenient laboratory marker of iodine deficiency. The method is
useful for the rapid and low-cost assessment of iodine deficiency. Our results suggested that urinary iodine concentration
might be a useful marker for prediagnosing preeclamptic women. In addition, iodine supplementation may also be considered
for preeclamptic therapy. 相似文献

Preeclampsia remains a leading cause of maternal and perinatal mortality and morbidity worldwide; however, its specific etiology still remains obscure. Some studies implicate poor maternal selenium status predisposing the mother to preeclampsia. This study was designed to determine changes in plasma selenium levels in women having preeclampsia as compared with those with normal pregnancy. In a nested case–control study, 650 normal primigravida in their first 24–28 weeks participated in the study. After 3 months of follow-up of all subjects, blood selenium levels were measured in 38 women presenting consecutively with preeclampsia and in 38 women having a normal pregnancy by atomic absorption spectrophotometry. Birth outcomes were recorded, such as gestational age at delivery, height, weight, birth head circumflex and 1-min Apgar score. Preeclampsia affects about 5.84 % of pregnancies, and in our study, there were no significant differences in age, anthropometric indices, and family history of preeclampsia between the preeclamptic and control groups. The selenium concentrations in plasma in women with preeclampsia were significantly lower as compared with those in women with normal pregnancy (70.63?±?21.41 versus 82.03?±?15.54 μg/L, p?<?0.05). Being in the bottom tertile of selenium concentration (less than 62.2 μg/L) was associated with greater risk of preeclampsia in pregnant women. The reduced selenium in the maternal circulations observed in the preeclamptic mothers support the hypothesis that insufficient selenium concentration may be a contributing factor to the pathophysiological mechanisms associated with preeclampsia, and optimizing the dietary selenium intake through supplementation could produce demonstrable clinical benefits. 相似文献

Ghrelin, leptin, and adiponectin play an important role in the regulation of energetic homeostasis, but physiological relationships between these hormones have not been elucidated. This study was therefore designed to characterize the association between serum acylated ghrelin, leptin, and adiponectin levels, as well as insulin resistance evaluated by homeostasis model of assessment in 32 normal-weight and 60 age-matched metabolically healthy obese women. In normal-weight, but not in obese women, we found a positive linear correlation between leptin and ghrelin (r=0.375; p=0.034). In the multiply regression analysis we observed the change of direction of leptin influence on acylated ghrelin level from positive in normal-weight (p=0.001) to negative in obese women without insulin-resistance (p=0.033); in obese women with insulin resistance leptin was not significantly associated with ghrelin. In neither group was any linear correlation found between ghrelin and adiponectin. However, by multivariate analysis adiponectin was positively associated with ghrelin, but only in obese women without insulin resistance (p=0.01). In conclusion, in normal-weight women leptin is positively correlated with acylated ghrelin. In obese women without insulin resistance different interactions between both hormones might reflect a physiological mechanism of adaptation to a positive energy balance. 相似文献

Increased serum heat-shock protein 70 levels reflect systemic inflammation, oxidative stress and hepatocellular injury in preeclampsia 总被引:1,自引:0,他引:1
Molvarec A Rigó J Lázár L Balogh K Makó V Cervenak L Mézes M Prohászka Z 《Cell stress & chaperones》2009,14(2):151-159
It has been previously reported that serum levels of 70-kDa heat-shock protein (Hsp70) are elevated in preeclampsia. The aim
of the present study was to examine whether increased serum Hsp70 levels are related to clinical characteristics and standard
laboratory parameters of preeclamptic patients, as well as to markers of inflammation (C-reactive protein), endothelial activation
(von Willebrand factor antigen) or endothelial injury (fibronectin), trophoblast debris (cell-free fetal DNA) and oxidative
stress (malondialdehyde). Sixty-seven preeclamptic patients and 70 normotensive, healthy pregnant women were involved in this
case-control study. Serum Hsp70 levels were measured with enzyme-linked immunosorbent assay (ELISA). Standard laboratory parameters
(clinical chemistry) and C-reactive protein (CRP) levels were determined by an autoanalyzer using the manufacturer’s kits.
Plasma von Willebrand factor antigen (VWF:Ag) levels were quantified by ELISA, and plasma fibronectin concentration by nephelometry.
The amount of cell-free fetal DNA in maternal plasma was determined by quantitative real-time polymerase chain reaction analysis
of the sex-determining region Y gene. Plasma malondialdehyde levels were measured by the thiobarbituric acid-based colorimetric
assay. Serum Hsp70 levels were increased in preeclampsia. Furthermore, serum levels of blood urea nitrogen, creatinine, bilirubin
and CRP, serum alanine aminotransferase and lactate dehydrogenase (LDH) activities, as well as plasma levels of VWF:Ag, fibronectin,
cell-free fetal DNA and malondialdehyde were also significantly higher in preeclamptic patients than in normotensive, healthy
pregnant women. In preeclamptic patients, serum Hsp70 levels showed significant correlations with serum CRP levels (Spearman
R = 0.32, p = 0.010), serum aspartate aminotransferase (R = 0.32, p = 0.008) and LDH activities (R = 0.50, p < 0.001), as well as with plasma malondialdehyde levels (R = 0.25, p = 0.043). However, there was no other relationship between serum Hsp70 levels and clinical characteristics (age, parity,
body mass index, blood pressure, gestational age, fetal birth weight) and laboratory parameters of preeclamptic patients,
including markers of endothelial activation or injury and trophoblast debris. In conclusion, increased serum Hsp70 levels
seem to reflect systemic inflammation, oxidative stress and hepatocellular injury in preeclampsia. Nevertheless, further studies
are required to determine whether circulating Hsp70 plays a causative role in the pathogenesis of the disease. 相似文献

BackgroundPreeclampsia, a rapidly progressing pregnancy-specific multi-systemic syndrome is globally the leading cause of maternal and neonatal morbidity and mortality. This study aims to evaluate the serum total Lactate dehydrogenase levels in women with preeclampsia when compared to normotensive pregnant women and assess the electrophoretic pattern of the LDH isoenzymes in normal pregnancy, preeclampsia and eclampsia.MethodsThe study, carried out in the Department of Biochemistry of MVJ Medical College, included 30 patients of preeclampsia and 30 normotensive gestational age-matched pregnant women admitted to the Department of OBG. Serum total LDH was analysed by DGKC method. Serum and cord blood samples for isoenzyme distribution analysis were collected from a normal pregnant woman undergoing delivery, a woman with mild eclampsia, two women with eclampsia, and analysed by slab gel electrophoresis followed by activity staining.ResultsLDH was significantly elevated in cases as well as between the case (mild and severe) groups, showed a moderate positive statistically significant correlation with systolic, diastolic blood pressure and a sensitivity of 50% and a specificity of 80%. Further, the isoenzyme pattern showed a decreasing distribution of aerobic forms of LDH in preeclampsia-eclampsia.ConclusionsSerum total LDH may serve as a robust and affordable marker of preeclampsia. Serum total LDH, along with its isoenzyme profile, might serve as a predictor and a stronger marker of preeclampsia when compared to serum LDH analysis alone. It may also be used to assess the severity of preeclampsia and hence help in predicting and preventing adverse maternal and foetal outcomes. 相似文献

It has been previously reported that circulating anti-heat-shock-protein (Hsp) antibody levels are elevated in cardiovascular
disorders. The aim of the present study was to determine circulating antihuman Hsp60, antimycobacterial Hsp65, and antihuman
Hsp70 antibody levels in healthy pregnant women and preeclamptic patients and to investigate their relationship to the clinical
characteristics of the study subjects, as well as to the markers of inflammation (C-reactive protein (CRP)), endothelial activation
(von Willebrand factor antigen), or endothelial injury (fibronectin), oxidative stress (malondialdehyde) and to serum Hsp70
levels. Ninety-three preeclamptic patients and 127 normotensive healthy pregnant women were involved in this case control
study. Serum anti-Hsp60, anti-Hsp65, anti-Hsp70, and Hsp70 levels were measured with enzyme-linked immunosorbent assay (ELISA).
Serum CRP levels were determined by an autoanalyzer using the manufacturer’s kit. Plasma von Willebrand factor antigen levels
were quantified by ELISA, while plasma fibronectin concentration by nephelometry. Plasma malondialdehyde levels were measured
by the thiobarbituric-acid-based colorimetric assay. For statistical analyses, nonparametric methods were applied. Anti-Hsp60,
anti-Hsp65, and anti-Hsp70 antibodies were detected in all of our serum samples. There were no significant differences in
serum anti-Hsp60, anti-Hsp65, and anti-Hsp70 antibody levels between the control and preeclamptic groups. Serum levels of
Hsp70 and CRP, as well as plasma levels of VWF antigen, fibronectin, and malondialdehyde, were significantly higher in preeclamptic
patients than in normotensive healthy pregnant women. Serum anti-Hsp60 antibody levels showed significant correlations with
serum anti-Hsp65 antibody levels both in the control and the preeclamptic groups (Spearman R = 0.55 and 0.59; p < 0.001, respectively). However, no other relationship was found between clinical features (maternal age, smoking status,
parity, body mass index, gestational age at blood draw, systolic and diastolic blood pressure, gestational age at delivery,
and fetal birth weight) and measured laboratory parameters of the study subjects and serum anti-Hsp antibody levels in either
study group. In conclusion, anti-Hsp60 and anti-Hsp70 antibodies as naturally occurring autoantibodies are present in the
peripheral circulation of healthy pregnant women. Nevertheless, humoral immunity against heat shock proteins was not associated
with preeclampsia. Further studies are warranted to explore the role of heat shock proteins and immune reactivity to them

目的:探讨应用脐动脉血流用于预测子痫前期新生儿和产妇结局的临床价值。方法:选择在我院产科建档分娩的120例孕产妇作为研究对象,根据子痫前期发病情况分为子痫前期组60例与对照组60例,记录和比较两组孕产妇的一般资料、血脂、血糖水平、分娩前脐动脉血流与新生儿体重、胎盘的重量及Apgar评分,并进行相关性与危险因素分析。结果:两组孕产妇的年龄、孕次、产次、流产次数、孕周等对比差异均无统计学意义(P0.05)。子痫前期组的血清HDL-C水平低于对照组(P0.05),血清TC、TG、LDL-C、FBG水平高于对照组(P0.05)。与对照组比较,子痫前期组脐动脉S/D、RI与PI值显著升高(P0.05)。所有孕产妇都顺利完成分娩,孕产妇与新生儿都存活,子痫前期组的新生儿出生体重及Apgar评分和胎盘的重量均显著低于对照组(P0.05)。在子痫前期组中,脐动脉S/D、RI、PI值与新生儿出生体重呈现显著负相关性(P0.05)。多重线性回归分析显示子痫前期孕产妇的脐动脉S/D、RI、PI值为影响新生儿出生体重的独立危险因素(P0.05)。结论:脐动脉血流与子痫前期新生儿出生体重显著相关,脐动脉S/D、RI、PI值为影响新生儿出生体重的独立危险因素,子痫前期脐动脉血流监测可为预测新生儿和产妇结局以及预后提供参考。 相似文献

Atherosis of spiral arteries in uteroplacental beds from preeclamptic women resemble those of atherosclerosis, characterized by increased plasma lipids and lipoproteins. We hypothesized that: 1) lipoprotein receptors/transporters in the placenta would be upregulated in preeclampsia, associated with increased maternal and fetal lipoprotein concentrations; and 2) expression of these would be reduced in preeclamptic placentae from women delivering small-for-gestational-age (SGA) infants. Placental biopsies and maternal and umbilical serum samples were taken from 27 normotensive and 24 preeclamptic women. Maternal/umbilical cord serum LDL, HDL, total cholesterol, and triglycerides were measured. Placental mRNA expression of lipoprotein receptors/transporters were quantified using quantitative RT-PCR. Protein localization/expression of LDL receptor-related protein 1 (LRP-1) in the preeclamptic placentae with/without SGA was measured by immunohistochemistry. Placental mRNA expression of all genes except paraoxonase-1 (PON-1), microsomal triglyceride transfer protein (MTTP), and protein disulfide isomerase family A member 2 (PDIA2) were observed. No differences for any lipoprotein receptors/transporters were found between groups; however, in the preeclamptic group placental LRP-1 expression was lower in SGA delivering mothers (n = 7; P = 0.036). LRP-1 protein was localized around fetal vessels and Hofbauer cells. This is the first detailed study of maternal/fetal lipoprotein concentrations and placental lipoprotein receptor mRNA expression in normotensive and preeclamptic pregnancies. These findings do not support a role of altered lipid metabolism in preeclampsia, but may be involved in fetal growth. 相似文献
