The Association between Polymorphism of TNF-α Gene and Hypertensive Disorder Complicating Pregnancy

To study whether the development of hypertensive disorder complicating pregnancy is associated with --308G→A, -850C→T mutation at promoter of TNF-α gene, the --308G→A, --850C→T polymorphism was examined in patients and healthy pregnant women by PCR-RFLP technique. The frequencies of genotype and allele were compared between the two groups. The results showed that with-308G→A polymorphism distribution, the allele frequency of TNF2 and the frequency of the genotype TNF2/1 in the patient group was significantly higher in the patient group than in control group （P〈0.05）. A significant difference in genotype distribution of --850C→T polymorphism was observed between the two groups. The allele frequencies of T in patient group was higher in the control group as compared with the patient group. The frequencies of CT and TT genotypes were lower in the patient group. It is concluded that the TNF2 allele of -308 is associated with the occurrence of hypertensive disorder complicating pregnancy, while T allele of--850 may be the protective factor against the development of the disease. TNF2/1 CC may be susceptibility genotype of hypertensive disorder complicating pregnancy.

Endogenous Ouabain in Hypertensive Disorder Complicating Pregnancy

Expression of endogenous ouabain in placenta and the concentrations of serum ET-1 and NO were examined in 30 patients with hypertensive disorder complicating pregnancy （HDCP） and 30 healthy pregnant women to investigate the effect of endogenous ouabain on HDCP. Compared with the healthy pregnant group, the expression of endogenous ouabain dramatically increased in the HDCP groups （P〈0.01）. There was a significantly positive correlation between the expression of en- dogenous ouabain with ET-1 （r= 0.5567, P〈0.01）, while the correlation of endogenous ouabain and NO was significantly negative （r=-0.6895, P〈0.01）. As expected, the correlation between ET-1 and NO was negative （r=-0.7796, P〈0.01）. ET-1 concentrations of maternal and cord sera in HDCP groups were significantly higher in comparison with healthy pregnant group （P〈0.01）. On the contrast, NO concentrations were much lower in the maternal and cord sera of HDCP groups as compared with healthy pregnant group （P〈0.01）. Our data suggest that endogenous ouabain is directly involved in the nosogenesis of HDCP, with accompanying decreased NO and the elevated of ET-1.

The investigation for the relationship among serum leptin, erythrocyte membrane Ca^(2+)-ATPase activity and hypertensive disorder complicating pregnancy

Objective： To study the significance of Leptin and the activity of erythrocyte membrane Ca^2＋-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 μ mol·pi/mg·h;eclampsia：1.12 ± 0.14 μmol·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.

Objective:To study the correlation between central retinal artery hemodynamic characteristics in patients with hypertensive disorder complicating pregnancy and endothelial injury molecules as well as trophoblast cell apoptosis molecules.Methods: 45 healthy pregnant women, 37 patients with gestational hypertension and 24 patients with preeclampsia who gave birth in Obstetrics Department of our hospital between May 2013 and December 2015 were selected and included in the control group, GH group and PE group respectively. Central retinal artery ultrasonography was done to determine peak systolic velocity (PSV), end-diastolic velocity (EDV) and resistance index (RI), serum was collected to determine interleukin-6 (IL-6), IL-17, IL-24, chemokine ligand 10 (CXCL10) and cartilage glycoprotein 40 (YKL40) content, and placenta tissue was collected to determine Fas, FasL, Bax, Caspase-3, Caspase-9, XIAP, Survivin and Livin expression.Results: Central retinal artery PSV and EDV as well as XIAP, Survivin and Livin expression in placenta of GH group and PE group were significantly lower than those of control group (P<0.05) while central retinal artery RI, serum IL-6, IL-17, IL-24, CXCL10 and YKL40 content as well as Fas, FasL, Bax, Caspase-3 and Caspase-9 expression in placenta were significantly higher than those of control group (P<0.05). Central retinal artery PSV and EDV as well as XIAP, Survivin and Livin expression in placenta of PE group were significantly lower than those of GH group (P<0.05) while central retinal artery RI, serum IL-6, IL-17, IL-24, CXCL10 and YKL40 content as well as Fas, FasL, Bax, Caspase-3 and Caspase-9 expression in placenta were significantly higher than those of GH group (P<0.05). Serum IL-6, IL-17, IL-24, CXCL10 and YKL40 content as well as Fas, FasL, Bax, Caspase-3 and Caspase-9 expression in placenta were negatively correlated with PSV and EDV, and positively correlated with RI;XIAP, Survivin and Livin expression in placenta were positively correlated with PSV and EDV, and negatively correlated with RI. Conclusions:Central retinal artery blood flow characteristics in patients with hypertensive disorder complicating pregnancy are the significantly increased blood flow resistance and the significantly decreased blood flow volume, and the above blood flow characteristics are associated with maternal endothelial injury and trophoblast cell apoptosis.

Changes in Number and Biological Function of Endothelial Progenitor Cells in Hypertension Disorder Complicating Pregnancy

To examine the changes in number and function of endothelial progenitor cells （EPCs） from peripheral blood （PB） in hypertension disorder complicating pregnancy （HDCP）, 20 women with HDCP and 20 normal pregnant women at the third trimester were studied. Mononuclear cells （MNCs） from PB were isolated by Ficoll density gradient centrifugation. EPCs were identified by positive expression of both CD34 and CD133 under fluorescence microscope and positive expression of factor Ⅷ as shown by immunocytochemistry. The number of EPCs was flow-cytometrically determined. Proliferation and migration of EPCs were measured by MTT assay and modified Boyden chamber assay, respectively. The adhesion activity of EPCs was detected by counting the number of the adherent cells. The results showed that, compared with normal pregnant women, the number of EPCs was significantly reduced in HDCP （4.29%±1.21% vs 15.32%±2.00%, P〈0.01）, the functional activity of EPCs in HDCP, such as proliferation （13.45%±1.68% vs 18.45%±1.67%）, migration （37.25±7.28 cells/field vs 67.10±9.55 cells/field） and adhesion activity （20.65±5.19 cells/field vs 34.40±6.72 cells/filed） was impaired （P〈0.01）. It is concluded that the number and function of EPCs are significantly decreased in HDCP.

Use of metformin during pregnancy for women with polycystic ovary syndrome

Objective: The purpose of this article is to review the literature assessing foetal and maternal pregnancy outcomes in women with PCOS who used metformin during pregnancy. Study Design: A literature search was conducted using MEDLINE, with analysis of 25 studies that recorded neonatal and maternal outcomes in women who used metformin during pregnancy. The outcomes assessed in this review include congenital deformities, miscarriages, preterm labour, gestational diabetes (GDM) and pregnancy induced hypertension (PIH). Results: We found that the use of metformin throughout pregnancy correlated with decreased rates of preterm labour, GDM and PIH. Conflicting evidence exists over whether metformin use during pregnancy reduced miscarriage rates. The use of metformin during pregnancy did not increase teratogenicity risks. Conclusion: The use of metformin throughout pregnancy is associated with decreased rates of preterm labour, GDM, and PIH. However, more randomised controls involving larger numbers of participants are required for more definitive results.

Pregnancy complications effect on the nickel content in maternal blood,placenta blood and umbilical cord blood during pregnancy

BACKGROUND Nickel(Ni)may accumulate in the human body and has biological toxicity and carcinogenicity.Ni has an extensive impact on the health of pregnant women and fetuses during gestation.AIM To evaluate Ni exposure in pregnant women in Kunming,Yunnan Province,China;to describe the distribution of Ni in the maternal-fetal system and placental barrier function;and to investigate the effect of Ni exposure on fetal health in mothers with pregnancy complications.METHODS Seventy-two pregnant women were selected using a case-control design.The women were divided into two groups:The control group(no disease;n=29)and the disease group[gestational diabetes(GDM),hypertensive disorder complicating pregnancy(HDCP),or both;n=43].The pregnant women in the disease group were further divided as follows:14 cases with GDM(GDM group),13 cases with HDCP(HDCP group)and 16 cases with both GDM and HDCP(disease combination group).Basic information on the pregnant women was collected by questionnaire survey.Maternal blood,placenta blood and cord blood were collected immediately after delivery.The Ni content in paired samples was determined using inductively coupled plasma mass spectrometry.RESULTS Compared to the control group,age was higher and body mass index was greater in pregnant women in the disease groups(28.14±2.54 vs 28.42±13.89,P<0.05;25.90±3.86 vs 31.49±5.30,P<0.05).The birth weights of newborns in the HDCP group and the control group were significantly different(2.52±0.74 vs 3.18±0.41,P<0.05).The content of Ni in umbilical cord blood in the entire disease group was higher than that in the control group(0.10±0.16 vs 0.05±0.07,P<0.05).CONCLUSION In the maternal-fetal system of women with pregnancy complications,the barrier effect of the placenta against Ni is weakened,thus affecting healthy growth of the fetus in the uterus.
