OBJECTIVETo study the relationship between pregnancy-induced hypertension (PIH) and catecholamine levels.

METHODSCatecholamines levels in maternal and fetal blood were determined in 116 patients with PIH and 40 normal control subjects using high performance liquid chromatography. The normal control subjects and PIH cases were selected from patients at term pregnancy receiving elective cesarean section.

RESULTSPlasma norepinephrine (NE) levels were significantly higher in patients with severe PIH than those in control subjects (P < 0.05). Both patients and control subjects had higher NE levels in the umbilical artery blood than in the umbilical vein blood (P < 0.05). NE levels in the umbilical artery blood were five times higher than those in the maternal blood.

CONCLUSIONThe pathogenesis of PIH may relate to catecholamine concentrations in fetus.

BackgroundFacing the increasing prevalence of gestational diabetes mellitus (GDM), this study aimed to evaluate the management of GDM and its association with adverse pregnancy outcomes.

MethodsThe data of 996 inpatients with GDM who terminated pregnancies in our hospital from January 2011 to December 2015 were collected. Treatments during pregnancy and the last hospital admission before delivery were analyzed. Pregnancy outcomes of the GDM patients were compared with 996 nondiabetic subjects matched by delivery year and gestational age. The association between fasting plasma glucose (FPG) and adverse pregnancy outcomes was examined by logistic regression analyses.

ResultsThe average prevalence of GDM over the 5 years was 4.4% (1330/30,191). Within the GDM patients, 42.8% (426/996) received dietary intervention, whereas 19.1% (190/996) received insulin treatment. Adverse outcomes were more likely to occur in patients with unsatisfactory control of blood glucose such as respiratory distress syndrome (RDS, χ = 13.373, P < 0.01). Elevated FPG was identified as an independent risk factor for premature birth (odds ratio [OR] = 1.460, P < 0.001), neonatal care unit admission (OR = 1.284, P < 0.001), RDS (OR = 1.322, P = 0.001), and stillbirth (OR = 1.427, P < 0.001).

ConclusionsManagement of GDM in the real world of clinical practice was unsatisfactory, which might have contributed to adverse pregnancy outcomes.

A 29-year-old woman presented with secondary amenorrhea, primary infertility, and virilization, which had developed over the past 2 years was suspected to have a virilizing tumor at her left ovary. Her serum testosterone level was markedly elevated (380 ng/dL). Left salpingooophorectomy was performed, and histopathological examination revealed a thecoma of the left ovary. The postoperative serum testosterone level returned to 65 ng/dL. The patient did not have regression of virilism soon. However, the patient had a normal menstruation 29 days after surgery and gave birth to a baby 13 months after surgery.

This study was attempted to observe the rate of oxygen desaturation after full oxygenation in six parturients scheduled for Cesarean sections and six patients scheduled for transabdominal hysterectomies. We calculated the mean rate of fall of arterial saturation (slope of desaturation: less than SaO2 (t2)-SaO2(t1) greater than/t2-t1) and changes in arterial blood gases were observed. All subjects were denitrogenated then a single isolated apnea was carried out. The mean time to obtain 90% saturation was longer in the nonpregnant group (7.5 min vs 3.6 min in parturients). The mean slope of desaturation was steeper in the parturients (-3.34) than the nonpregnant group (-1.52). As far as the oxygen reserve is concerned, the parturients had a lesser margin of safety than the nonpregnant women. It was concluded that the lower the thoracic gas volume (parturients), the lower the alveolar O2 stores and, the more rapidly these stores are depleted.

OBJECTIVETo evaluate the clinical significance of umbilical activin A in preterm infants.

METHODSForty-one preterm infants (gestation 28 to 36 weeks) were enrolled. Fetal membranes, umbilical cords and blood samples from umbilical vein were obtained. Umbilical activin A level was measured using ELISA. The histological examinations of fetal membranes and umbilical cords were performed.

RESULTSThe umbilical level of activin A averaged 2069 pg/mL in the 41 preterm infants. The umbilical activin A level in the 5 infants with intrauterine infection was higher than in those without intrauterine infection (2510 pg/mL vs 1975 pg/mL; P<0.01). Umbilical activin A level at cutoff of 2490 pg/mL showed a sensitivity of 80.0% and a specificity of 90.6% as a marker of intrauterine infection. There were no significant differences in the umbilical activin A level between the infants with and without respiratory distress syndrome. Umbilical activin A level was positively correlated with the duration of postnatal oxygen therapy (r=0.326, P<0.05).

CONCLUSIONSUmbilical activin A may serve a marker of intrauterine infection in preterm infants. The umbilical activin A level is correlated with the duration of postnatal oxygen therapy.

ABNORMALITIES during pregnancy are regarded as pathological pregnancy. Early detection of anomalies is urgent to take measures as soon as possible to prevent serious pregnancy complications. Procoagulant-anticoagulant imbalance is often the pathological basis of many pathological pregnancy conditions, leading to a hypercoagulable state. We compared the thromboelastographic parameters between pathological pregnancy and normal pregnancy patients, evaluated the value of thromboelastography in early detecting pathological pregnancy and predicting postpartum hemorrhage.
