Plasma motilin concentration in the second and third trimesters of pregnancy and postpartum

Plasma motilin concentrations were measured in 135 women during the second and third trimesters of pregnancy and 3～5 d after delivery and the results were compared with those of 20 healthy nonpregnant women.The mean plasma motilin concentration (323.96± 125.10 ng/L) in women during the second trimester of pregnancy was lower than in healthy nonpregnant women (366.12±96.23 ng/L) (P<0.05),but that was significantly higher than in women during the third trimester of pregnancy (121.04±27.00 ng/L) (P<0.01);the plasma motilin concentration in women during 3～5d after delivery (443.05±140.79 ng/L) was significantly higher than that in pregnant women (P<0.01).The results showed that pregnancy appears to have a profound inhibitory effect on plasma motilin,and this may partly be responsible for the gastrointestinal hypomotility associated with pregnancy.

A perspective study and financial analysis of different protocols of second trimester maternal serum screening for Down's syndrome

Objective:To compare the efficiency and related financial parameters of the double- and triple-marker test for the second-trimester maternal serum screening for Down's syndrome. Methods:The serum samples were collected from the 2^(nd) trimester pregnant women in this hospital and were examined for three biomedical markers[alpha-fetoprotein(AFP),freeβ-human chorionic gonadotropin(freeβ-hCG) and unconjugated estriol(uE_3)]by TR-FIA.The pregnancy outcomes were followed up and screening efficiency calculated for double-marker(AFP+freeβ-hCG) and triple-marker(AFP+ freeβ-hCG+uE_3) test. Results:(1)A total of 4,707 serum samples of 2^(nd) trimester pregnancy were collected in this study,of which 4,245 pregnancy outcomes got followed up by May 30,2009,with 462 cases lost to follow-up.The follow-up rate was 90.2%.3 cases of Down's syndrome,4 cases of other chromosome abnormalities and 1 case of neural tube defect (NTD) were found.There was no medically induced miscarriage by invasive tests.(2) Detection rate and false positive rate of triple marker test for Down's syndrome screening were 66.7%and 5.26%,respectively,while those in double marker test were 33.3%and 4.01%,respectively.The detection rate of all chromosome abnormalities was 75%in triple marker test and 37.5%in double marker test.The detection rate of NTD was 100%either in double or triple marker test.(3) It costs 499,375 RMB to avoid one Down's syndrome birth by using triple marker test and 781,200 RMB by using double marker test. Conclusion:Triple-marker test is superior to double marker test in 2nd trimester maternal serum screening for Down's syndrome,and costs less to avoid a Down's syndrome birth.

Comparison of Preliminary Clinical Efficacy for Two Cervical Preparations for Early Second-trimester Pregnancy Termination at 12-17 Weeks Gestation

Objective To compare clinical efficacy for two cervical preparations for early secondtrimester pregnancy termination at 12-17 weeks gestation. Methods Seventy healthy women aged 18-41 years requesting legal termination of pregnancy at 12-17 weeks of gestation were equally randomized into two groups. Two cervical preparations, the Dilapan-STM combined with mifepristone and misoprostol （DMM） method, and the mifepristone combined with misoprostol （MM） method, were used to end early second-trimester pregnancy for group DMM and group MM, respectively. Clinical outcomes and complications for these two methods were compared. Results No differences were found on rates of successful abortion within 48 h and blood loss after abortion at 2 h between the two groups （P〉0.05）. DMM group had significant shorter induction-to-abortion interval and hospital stay compared with group MM （P〈0.01）. In both DMM and MM groups, side effects including nausea/vomiting, diarrhea, chills and rigors, and fever occurred, and incidences of these side effects were no difference （P〉0.05）. Conclusion DMM method would have similar clinical efficacies with MM method for early second-trimester pregnancy termination. Besides,DMM method has shorter induction-to-abortion interval and hospital stay, which benefits its clinical application.

Influence of Vitamin D Level in the Second Trimester of Pregnancy on the Complications of Chinese Pregnant Women and Fetuses

Background:Vitamin D has been found to have more biological effects beyond the traditional research range,which involve in immunoregulation,occurrence,and development of tumor,reproduction,cell differentiation,and so forth.Herein,the influence of Vitamin D level in the second trimester of pregnancy on the Chinese pregnant women and fetal weight was investigated.Methods:Totally 1,612 pregnant women were followed up during the study,the 25-hydroxyvitamin D(25(OH)D)level was measured with ELISA at the 16th gestational week,and the fasting blood glucose was measured with hexokinase method using an automatic biochemistry analyzer at the same time.At week 24,oral glucose tolerance test(OGTT)was performed to test the blood glucose level(fasting blood glucose,1 h and 2 h after oral administration of glucose).Besides,other indices(e.g.,fetal birth weight)were recorded and analyzed by SPSS version 19.0 software.Results:Pearson’s correlation analysis indicated that the serum 25(OH)D had a negative correlation with blood glucose at 1 h after oral glucose administration at week 24 in OGTT(correlation coefficient:−0.03,P=0.01).However,it did not have correlations with the fasting blood glucose at weeks 16 and 24 as well as the blood glucose at 2 h after oral glucose administration at week 24.The Pearson’s correlation analysis was used to analyze the correlation between Vitamin D level in the pregnant women and fetal birth weight,and there was no correlation between them.Conclusion:The Vitamin D level in the second trimester of pregnancy had a negative correlation with blood glucose glucose at 1 h after oral glucose administration and had no correlation with fetal birth weight.

Successful Deliveries of Twins from Two Pregnant Women Following Preterm Prelabor Rupture of Membranes in the Early Second-Trimester Pregnancy

The management of preterm prelabor rupture of membranes (PPROM) before 34 weeks of gestation is intractable, due to pulmonary immaturity, many complications, poor pregnancy outcomes. In particular, the pre-viable PPROM (<23 weeks of gestation) is much more difficult to be treated. The clinical recommendation is to terminate the pregnancy as soon as possible. The pregnancy outcomes of PPROM in the early second-trimester of two twin pregnant women in our hospital were reported to explore the treatment protocols. The pregnancies of the two women developed PROM at 12 and 16 weeks of gestation, respectively. After expectant treatment, they were deliveried successfully at 34+6 and 34+4 weeks of gestation, respectively. The assessment of growth and development of infants was normal during the following six months after birth. Therefore, if PPROM occurs in the early second-trimester of pregnancy, the management of PPROM should be individualized, it’s a long process which should include comprehensive communication between patients and families regarding alternative treatment options (including expectant management) and risks and benefits of the procedure. In the absence of spontaneous labor or occurrence of complications that would prompt delivery (intra-amniotic infection, abruptio placenta, cord prolapse), and fetal status is normal, the patients should proceed with expectant treatment, induction of labor is commonly performed in pregnancies with PPROM ≥34 weeks of gestation.

Maternal Thyroid-Stimulating Hormone Level and Thyroid Peroxidase Antibody Status in the First and Second Trimester of Pregnancy and Their Relationship with the Risk of Gestational Diabetes Mellitus

Objective:To investigate thyroid-stimulating hormone(TSH)levels and thyroid peroxidase antibody(TPOAb)in early pregnancy and to estimate the risk of development of gestational diabetes mellitus(GDM).Methods:The levels of TSH,free thyroxine,free triiodothyronine,and TPOAb were retrospectively evaluated in 2333 pregnant women.All women recruited were divided into groups of TSH high(H),TSH low(L),TSH(H)TPOAb positive(+),TSH(H)TPOAb negative(-),TSH normal(N)TPOAb(+),TSH(L)TPOAb(+),TSH(L)TPOAb(-),and estimated the risk of GDM.Results:TSH level(X^(2)=13.0024,P=0.0015)and TSH combined TPOAb(X^(2)=20.0038,P=0.0012)were correlated to development of GDM.The level of TSH in 95 women was increased,and in 216 women were decreased.Of the 2333 pregnant women,546 patients were diagnosed with GDM,with a prevalence of 23.40%.The prevalence of GDM was 35.78%and 28.70%for the TSH high(H)and TSH low(L)pregnant women,respectively.The increased TSH(P=0.0013,odds ratio:2.09,confidence interval:1.34-3.28)was correlated to increase GDM incidence.TSH(H)TPOAb(+)(n=29),TSH(H)TPOAb(-)(n=58),TSH normal(N)TPOAb(+)(n=265),TSH(L)TPOAb(+)(n=30),TSH(L)TPOAb(-)(n=154)were in this study.The prevalence of GDM was 51.72%,29.31%,23.02%,26.67%,and 29.87%for the TSH(H)TPOAb(+),TSH(H)TPOAb(-),TSH(N)TPOAb(+),TSH(L)TPOAb(+),and TSH(L)TPOAb(-)pregnant women,respectively.Only the TSH(H)TPOAb(+)pregnant women had a significant higher incidence of GDM(P=0.0018,odds ratio:3.63,confidence interval:1.62-8.16).Trimester specific results showed that only second trimester had higher GDM risk either analyze TSH or the combination of TSH and TPOAb.Conclusion:Elevated TSH level and TPOAb positive in the second trimester of pregnancy were correlated to an increased risk of GDM.

Comparison of second-trimester maternal serum free-p-human chorionic gonadotropin and a-fetoprotein between normal singleton and twin pregnancies： a population-based study

Background The second-trimester maternal serum screening in twin pregnancy is still controversial, as the serum marker levels in twins are not as clear as those in singletons. This study aimed to evaluate the relationship between the levels of the second-trimester maternal serum free β-human chorionic gonadotropin （free β-HCG） and a-fetoprotein （AFP） in normal twin and singleton pregnancies and to estimate feasible analysis methods for utilizing these markers in second trimester screening for twin pregnancy. Methods On the basis of a prospective population-based study of second-trimester maternal serum screening, the concentrations of maternal serum AFP and free β-HCG of 195 normal twin pregnancy and 26 512 singleton controls at gestational weeks 15 to 20 were measured by time-resolved fluoroimmunoassay in one laboratory. The levels of markers were compared between the twins and singletons using weight-correction and gestational age-specific model. Results According to the research protocol, 95 communities were randomly sampled, which covered the whole Jiangsu province, the east of China. A total of 26 803 pregnant women （98%）, from the target population accepted prenatal screening for maternal serum AFP, β-HCG detection, and all babies were followed up for at least six months. There were 197 （0.73%） twin pregnancies, of which one case had fetal trisomy 18, and one case with fetal anencephaly. The others were normal twin pregnancy. From a total enrollment of 26 803 women participants, 26 512 women with normal singleton pregnancies were selected as the model controls. The other 291 pregnancies, including trisomy 21, neural tube defect （NTD）, trisomy 18, and other fetal abnormalities, were excluded. No significant differences were found in the medians of gestational age-specific maternal serum free β-hCG and AFP in normal twin pregnancy comparing with twice those in model controls with the exception of the medians for free β-hCG during the 16th gestational week （P=0.012）. Conclusion The weight-correction and gestational age-specific levels of Chinese Han population maternal serum free β-hCG and AFP in normal twins were twice the levels as those in the singleton controls during the 17-19 gestational weeks.

目的:分析眼动脉收缩期第二与第一峰值血流速度比(B/A)值和子宫动脉收缩期、舒张期流速比(S/D)值对子痫前期(PE)的预测价值。方法:回顾性收集2021年1月-2023年2月本院产前检查并分娩孕妇,根据结果分为PE组(PE孕妇,n=41)与对照组(健康孕妇,n=162),于孕15~20周测量孕妇眼动脉B/A值以及子宫动脉S/D值,并绘制受试者工作特征(ROC)曲线分析两项指标对PE的预测价值。结果:PE组围产儿死亡率、新生儿转新生儿重症监护室率以及孕妇并发症发生率均高于对照组,眼动脉B/A值(0.71±0.15)与子宫动脉S/D值(3.27±0.76)均高于对照组(0.49±0.11、1.99±0.53)(均P<0.05)。眼动脉B/A值与子宫动脉S/D值预测PE的效能分别为曲线下面积值0.945、0.875,敏感度87.8%、78.1%,特异度93.2%、89.5%(P>0.05)。结论:PE孕妇妊娠15~20周测量眼动脉B/A值与子宫动脉S/D值均异常高于健康孕妇,二者预测PE均有良好效能,可应用于临床。

孕妇孕中期血清PAPP-A联合Inhibin-A水平预测出生缺陷的临床价值

目的:探讨孕中期孕妇血清妊娠相关蛋白A(PAPP-A)、抑制素A(Inhibin-A)表达水平及其预测出生缺陷的临床价值。方法:收集本院2021年1月—2024年5月定期产前检查并分娩的孕妇临床资料,其中妊娠结局为胎儿结构异常孕妇86例(异常组),妊娠结局为正常新生儿的孕妇90例(对照组),比较两组血清PAPP-A、Inhibin-A水平,Pearson分析异常组血清PAPP-A、Inhibin-A水平相关性,logistic分析发生出生缺陷的影响因素,受试者工作特征曲线分析血清PAPP-A联合Inhibin-A预测出生缺陷的临床价值。结果:异常组血清PAPP-A(7.33±1.48 ng/ml)低于对照组(9.56±1.74 ng/ml),Inhibin-A(478.25±93.48 pg/ml)高于对照组(365.87±81.51 pg/ml)(均P<0.05),异常组血清PAPP-A与Inhibin-A呈负相关(r=-0.340,P=0.001),异常组服用叶酸占比低于对照组,孕早期呼吸道感染、孕期贫血、饲养动物、吸烟占比均高于对照组(均P<0.05);服用叶酸、血清PAPP-A升高是出生缺陷发生的保护因素,孕早期呼吸道感染、孕期贫血、吸烟、血清Inhibin-A升高是出生缺陷发生的危险因素(均P<0.05)。血清PAPP-A预测出生缺陷的曲线下面积(AUC)为0.802,敏感性79.1%、特异性80.0%;血清Inhibin-A预测出生缺陷的AUC为0.803,敏感性74.4%、特异性81.1%,血清PAPP-A联合Inhibin-A预测出生缺陷的AUC为0.874,敏感性91.9%、特异性75.6%(P<0.05)。结论:孕妇孕中期血清PAPP-A降低、Inhibin-A水平升高不利于胎儿正常生长发育,孕中期血清PAPP-A联合Inhibin-A预测出生缺陷临床价值提高,提示临床未来可能用于出生缺陷的临床预测。

血清GATA6和SMAD3表达水平对孕中期胎儿心血管畸形的诊断价值

目的探究孕中期孕妇血清GATA结合6(GATA6)、SMAD同源物3(SMAD3)表达水平对胎儿心血管畸形的诊断价值。方法选取2017年6月至2023年6月北部战区总医院收治的有高危胎儿心血管畸形风险的孕中期孕妇203例作为研究对象,根据随访结果,45例孕妇胎儿确诊为心血管畸形(疾病组),158例孕妇胎儿心脏发育正常(对照组)。采用荧光定量PCR法和酶联免疫吸附(ELISA)法分别检测孕中期孕妇血清GATA6 mRNA、SMAD3表达水平。受试者工作特征(ROC)曲线分析孕中期孕妇血清GATA6 mRNA、SMAD3对胎儿心血管畸形的诊断价值。结果疾病组孕妇血清GATA6 mRNA、SMAD3表达水平均低于对照组,差异有统计学意义(t值分别为4.210、7.185,P<0.05);孕中期孕妇血清GATA6 mRNA、SMAD3二者联合诊断胎儿心血管畸形的曲线下面积(AUC)为0.95,优于各自单独诊断(Z值分别为5.41、5.23,P<0.05);联合诊断的灵敏度和特异度分别为97.78%、79.11%。结论胎儿心血管畸形的孕中期孕妇血清GATA6 mRNA、SMAD3表达水平均较低,二者联合检测对胎儿心血管畸形有较好的诊断价值。
