Objective To investigate the different expressions of various subtypes of human leukocyte antigen-G(HLA-G)mRNA in placentas among early and late-onset severe preeclamptic and normal pregnant women. Methods Eleven placental samples from early-onset severe preeclamptic pregnancies and fourteen from late-onset severe preeclamptic pregnancies were collected as study group;eight placental samples from normal pregnancies were collected as control group.The levels of HLA-G mRNA in the three groups were measured by nested RT-PCR. Results Compared with the counterparts in the control group,the leveI of HLA-G1 subtype was significantly decreased (median:Early-onset group:1.37,P<0.05;Late-onset group:24.90,P<0.05;Control group:46.67,P<0.05)and the level of HLA-G5 subtype increased(median:Early-onset group 19.23;Late-onset group:3.65;Control group:1.33)in both early and late-onset severe preeclamptic group.The level of HLA-G2 subtype increased(median:Early-onset group:0;Late-onset group:21.59,P<0.05;Control group:5.39)in the late-onset severe preeclamptic group. Conclusion The reduced expression of HLA-G membrane-bound subtype mRNA in the placenta and the increased expression of HLA-G soluble subtype mRNA in the placenta may be related tO the pathogenesis of preeclampsia.

To analyze maternal and neonatal complications among late preterm birth cases and to investigate risk factors of late preterm birth. Methods This was a retrospective analysis of 258 late preterm cases (late preterm group) born in Peking University First Hospital from January 1, 2009 to December 31, 2010. Maternal comorbidity and complications, delivery modes, and neonatal complications of these 258 late preterm infants were compared with 308 term cases (term group) during the same period. Statistical analysis was performed usingχ2 test, Fisher's exact probability test, t test and logistic regression. Results In Peking University First Hospital, late preterm births accounted for 3.9%(258/6 695) of live births and 60.1%(258/429) of preterm births. The incidence of the following maternal complications among the late preterm group was higher than that among term group(all P<0.05): severe pre-eclampsia [7.4%(19/258) vs 1.0%(3/308), χ2=15.35]; preterm rupture of membrane [42.6%(110/258) vs 15.3%(47/308), χ2=52.49];cervical insufficiency [1.9%(5/258) vs 0.0%(0/308), Fisher's exact test];placenta previa[3.5%(9/258) vs 0.6%(2/308), Fisher's exact test] and placental abruption [2.7%(7/258) vs 0.3%(1/308), Fisher's exact test]. Severe pre-eclampsia was the major risk factor leading to late preterm birth. The incidence of the following neonatal complications among the late preterm group was higher than that among term group (all P<0.05):respiratory distress syndrome (NRDS) [11.6%(30/258) vs 1.6%(5/308), χ2=24.22]; hyperbilirubinemia [64.3%(166/258) vs 39.6%(122/308),χ2=34.36];electrolyte disturbance [12.8%(33/258) vs 1.6(95/308),χ2=27.96];hypothermia [7.0%(18/258) vs 2.9%(9/308),χ2=5.08];infectious pneumonia[13.6%(35/258) vs 3.2%(10/308), χ2=20.43]; leukoencephalopathy [3.1%(8/258) vs 0.3%(1/308), χ2=5.25]; low body temperature [18.6%(48/258) vs 3.6%(11/308),χ2=33.98] and neonatal asphyxia [6.2%(16/258) vs 1.0%(3/308),χ2=11.86]. The incidence of the following neonatal complications among late preterm infants born at<35 weeks gestation was higher than that among late preterm infants born at≥35 weeks gestation (all P<0.05):NRDS [30.4%(14/46) vs 7.5%(16/212) ,χ2=19.26];hyperbilirubinemia [91.3%(42/46) vs 58.5%(124/212), χ2=17.74]; electrolyte disturbance [21.7%(10/46) vs 10.8%(23/212), χ2=4.02]; intracranial hemorrhage [8.7%(4/46) vs 1.9%(4/212),χ2=3.88];leukoencephalopathy [10.9%(5/46) vs 1.4%(3/212),χ2=8.32] and neonatal asphyxia [15.2%(7/46) vs 4.2%(9/212), χ2=6.05]. Conclusions Severe pre-eclampsia is the major risk factor leading to late preterm birth. The incidence of complications among late preterm infants is higher than that among term infants. If a pregnancy has to be terminated because of maternal disorders, the pregnancy period should be extended to 35 weeks if it permits.

Objective To investigate clinical characteristics and outcomes of twin pregnancies complicated with growth discordance.Methods Five hundred and seventy-six twin pregnancies who delivered between January 1,2000 and July 31,2012 in Peking University First Hospital were retrospectively analyzed.Cases with twin-twin transfusion syndrome had been excluded.Fetal weight was estimated by abdominal circumference and femur length; neonatal birth weight was recorded.The weight difference between two babies was divided by the weight of the bigger one to obtain the differential ratio.Twin pregnancy complicated with growth discordance was diagnosed if the ratio was equal or greater than 25％ (discordance group,n=68),and growth concordance was diagnosed if the ratio was less than 25％ (concordance group,n=508).The incidence of twin pregnancies complicated with growth discordance was analyzed.The incidence of maternal complications,premature delivery,perinatal death and neonatal complications were compared between the two groups.Chisquare test and t test were used for statistical analysis.Results The incidence of twin pregnancies complicated with growth discordance was 11.8％ (68/576).The incidence of growth discordance in monochorionic twins was higher than that in dichorionic twins [17.6％ (40/227) vs 8.0％ (28/349),x2=11.40,P＜0.05].The gestational age at delivery in the discordance group was earlier than that in the concordance group [(35.6±4.1) weeks vs (36.6±3.2) weeks,t=-1.66,P＜0.05],and the incidence of premature delivery in the discordance group was higher than that in the concordance group [58.8％ (40/68) vs 47.6％ (242/508),x2=3.85,P＜0.05].The perinatal mortality in discordance group was higher than that in the concordance group [9.6％ (13/136) vs 4.7％ (48/1 016),x2=5.84,P＜0.05].Among babies in discordance group,the incidence of intracranial lesion in monochorionic twins was higher than that in dichorionic twins [20.9％ (14/67) vs 6.8％ (3/44),x2=4.06,P＜0.05].Conclusions Twin pregnancies with growth discordance are prone to adverse pregnancy outcomes.Prenatal care should be strengthened and fetal condition should be assessed timely.It is suggested that neonates should undergo overall checkup and long-term follow-up.

Objective To investigate the different expression of various subtypes of human leukocyte antigen-G(HLA-G)in placenta of patients complicated with severe pre-eclampsia.Methods Ten placental samples from early-onset severe pre-eclamptic pregnancies and ten from late-onset severe preeclamptic pregnancies were collected as study group; ten placental samples from preterm pregnancies and ten from normal pregnancies were collected as control group.The levels of HLA-G protein in the four groups were measured by western blot and immunohistochemistry.Results(1)HLA-G1 protein decreased significantly in both the early-onset(2.4 ± 0.6 versus 2.9 ± 1.1,P ＜ 0.05)and the late-onset pre-eclampsia groups (3.5 ± 2.1 versus 4.2 ± 2.4,P ＜ 0.05).(2)HLA-G5 protein increased in the late-onset pre-eclampsia groups(1.8 ± 1.1 versus 1.1 ± 0.9,P ＜ 0.05); the increase in the early-onset pre-eclampsia group is not obvious(1.6 ± 0.9 versus 1.4 ± 0.7,P ＞ 0.05).(3)The level of HLA-G1 protein in placenta from patients complicated with premature labor is lower(2.9 ± 1.1 versus 4.2 ± 2.4,P ＜ 0.05); HLA-G5 protein does not change significantly(1.4 ± 0.7 versus 1.1 ± 0.9,P ＞ 0.05).(4)HLA-G1 and G5 proteins mainly express in the placenta extravillous cytotrophoblast cells.There is also a high level of expression around the blood vessels and in the extraembryonic mesoderm.Conclusions(1)HLA-G1 decreased significantly in both the early-onset and late-onset pre-eclamptic patients.(2)HLA-G5 increased in both the early-onset and late-onset pre-eclamptic patients,and the increase in the late-onset pre-eclamptic patients is obvious.(3)In late pregnancy,the level of HLA-G1 is lower in patients complicated with premature labor,this may be the result of its earlier pregnancy week; HLA-G5 does not change significantly.(4)HLA-G1 and G5 mainly express in the placenta extravillous cytotrophoblast cells.

Objective To understand the clinical features,differential diagnosis,treatment and prognosis of postpartum hemolytic uremic syndrome (PHUS). Methods Three PHUS cases and relevant literature were reviewed. Results Three patients were admitted because of microangiopathie hemolytic anemia,thrombocytopenia and acute renal failure.which occurred within 3 days after cesarean section.All of them received plasmapheresis and hematodialysis.Now,one of the patients recovered,and the other lives on hematodialysis. Conelusiom Early diagnosis and proper treatment of PHUS ensures a better outcome.

Objective To evaluate the efficacy and safety for cervical ripening by double-balloon catheter among full-term pregnancy women underwent labor induction.Methods It was a prospective nonrandomly controlled research.Totally 128 singleton-pregnancy women in full-term who had to undergo labor induction because of pregnancy complications or comorbidities from August 2011 to April 2013 in Peking University First Hospital were selected as study subjects.Participants were allocated to preinduction cervical ripening with either a double-balloon catheter (66 participants,study group) or prostaglandin vaginal insert (62 participants,control group).Compare the efficacy for cervical ripening and adverse reactions between the two groups.Results The efficacy for cervical ripening (Bishop scores improved by ≥ 2) had no significant differences between study and control groups [82％ (54/66) compared with 81％ (50/ 62),P＞0.05].The time interval between intervention and parturiency was significantly higher in the doubleballoon catheter group than in the prostaglandin vaginal insert group [(24.2±8.5) compared with (14.5±8.0) hours,P＜0.05].The proportion of women who achieved parturiency within 12 hours was significantly lower in the double-balloon catheter group than that in the control group [9％ (6/66) compared with 21％ (13/62),P＜0.05].The cesarean section rate showed no significant differences [41％ (27/66) compared with 43％(27/62),P＞0.05].The prevalence of intrauterine infection demonstrated by clinical diagnosis was significantly higher in the double-balloon catheter group [11％ (7/66) compared with 6％ (4/62),P＜O.05].The double-balloon catheter group had significantly lower rates of contraction overfrequency [0(0/66) compared with 42％ (26/62),P＜0.05],hyperthermia [3％ (2/66) compared with 19％ (12/62),P＜0.05],fetal heart rate abnormalities before removing the device or drug [5％ (3/66) compared with 19％ (12/62),P＜0.05],as well as precipitate labour [2％ (1/66) compared with 16％ (10/62),P＜0.05].Conclusions The efficacy of a double-balloon transcervieal catheter is similar to that of a prostaglandin vaginal insert.However,the double-balloon catheter cannot significantly reduce the cesarean section rate while it increases the risk of intrauterine infection.The materual and fetal safety of transcervical catheter is superior to the prostaglandin vaginal insert.In cases of oligohydramnios,fetal growth restriction,pregnancy complicated with asthma,hypertension and scar uterine are in favor of a balloon catheter using for cervical ripening on account of high risk of using prostaglandin.

Objective To investigate clinical predictors in early pregnancy for adverse pregnancy outcomes in women complicated with chronic nephropathy. Methods One hundred and eighty-four pregnancies complicated with chronic nephropathy who delivered between January, 2005 and January, 2014 in Peking University First Hospital were retrospectively analyzed. Two hundred pregnant women without chronic nephropathy were selected as the control group. Pregnancy outcomes were compared between the two groups. Relationships between clinical predictors in early pregnancy [age, history of kidney disease, drugs used before pregnancy (in three months), results of renal biopsy, blood pressure, serum creatinine, urea nitrogen, 24 h urinary protein, estimated glomerular filtration rate, stage of chronic nephropathy] and adverse pregnancy outcomes [maternal mortality;pregnancy complicated by severe preeclampsia;renal function decline, early preterm birth, very low birth weight infants, fetal loss after 20 weeks of pregnancy] were assessed by logistic regression analysis. T-test, Chi-square test and multivariate regressions were used for statistical analysis. Results There were 174 and 197 livebirths in the study and the control groups, respectively. The most popular type of chronic nephropathy in pregnant women was IgA nephropathy (38.6%, 71/184). Compared with the control group, the risk of premature labor [9.8%(17/174) vs 3.0%(6/197), χ2=7.184], low birth weight infants[18.4%(32/174) vs 7.1%(14/197),χ2=9.813], very low birth weight infants [5.7%(10/174) vs 1.5%(3/197),χ2=4.536], fetal loss after 20 weeks of pregnancy [5.7%(10/184) vs 1.5%(3/200), χ2=4.536] and severe preeclampsia [17.9%(33/184) vs 1.5%(3/200), χ2=33.544] increased significantly in the study group (all P < 0.05). Twenty-four-hour urinary protein content (OR=1.84, 95%CI: 1.36-2.50, P=0.001) and mean arterial pressure (OR=1.04, 95%CI: 1.00-1.07, P=0.027) in early pregnancy were risk factors for adverse pregnancy outcomes. The risk of renal function decline increased significantly in patients with higher stages of chronic nephropathy in early pregnancy (OR=6.50, 95%CI: 3.34-8.21, P<0.01). Mother complicated by preeclampsia during pregnancy was an independent risk factor (OR=11.10, 95%CI: 4.48-27.20, P<0.01). Compared with women whose 24 h urinary protein content less than 1g in early pregnancy (122 livebirths within 126 cases), the risk of premature labor [17.3%(9/52) vs 6.6%(8/122), χ2=4.780], increased significantly in women whose 24 h urinary protein content were more than or equal to 1 g in early pregnancy (52 livebirths within 58 cases) (P<0.05). Conclusions Elevated urinary protein level and mean arterial pressure in early pregnancy were risk factors of adverse pregnancy outcomes. The risk of renal function decline increased in patients with higher stages of chronic nephropathy in early pregnancy. Mother complicated by preeclampsia during pregnancy was an independent risk factor for poor prognosis of the fetus.

Objective To analysis the relationship between gestational age and perinatal outcomes in patients complicated with early onset severe preeclampsia.Methods Retrospective study was conducted on clinical documents of 221 patients with early onset severe preeclampsia( ＜ 34 weeks) who delivered after 28 gestational weeks in Peking University First Hospital from July 1999 to June 2009.Patients were divided into three groups based on gestational weeks at delivery: group Ⅰ (n = 81 ) delivered at 28 -31 weeks+6,group Ⅱ (n = 78) at 32 -33 weeks+6 and group Ⅲ (n = 62) after 34 weeks.The clinical characteristics and perinatal outcomes were compared among those three groups.Results ( 1 ) Outcome of neonates:Among 221 neonates, 13 neonates lost follow-up, including 9 in group Ⅰ , 3 in group Ⅱ, 1 in group Ⅲ.The incidence of neonatal respiratory distress syndrome ( RDS ) of 26% ( 19/72 ) in group Ⅰ were significantly higher than 7% (5/75) in group Ⅱ and 10% (6/61) in group Ⅲ (P ＜ 0.05 ).The neonatal mortality rate of (43% ,31/72) in group Ⅰ were significantly higher than 3% (2/61) in group Ⅲ and 28%(21/75) in group Ⅱ (P ＜0.05 ).The incidence of maternal complications showed no statistical difference among three groups.(2) Neonatal death analysis: all neonatal death were due to parents' give up, including 26%(8/31) in group Ⅰ, 67% (14/21)in group Ⅱ and 1/2 in group Ⅲ, which reached statistical difference(P＜0.05).Conclusions The incidence of neonatal RDS in mother with early onset severe preeclampsia was decreased if delivered after 32 weeks, and the perinatal mortality was remarkably decreased if delivered after 34 weeks.Therefore, the perinatal survival rate in women with early onset severe preeclampsia can be improved by minimizing the impact of social factors.

Gestational hypertension disease is one of the most common complications in pregnancy,and is the second leading cause of maternal mortality in China.In recent years,researchers have found that activation of the complement system plays an important role in the pathogenesis of preeclampsia.In this paper,the authors reviewed previous literature to expound the role of abnormal complement system activation in the pathogenesis of gestational hypertension disease.At the same time,authors will introduce the clinical value of detection of complement system related factors in the diagnosis and differential diagnosis of gestational hypertension disease.
