Objective To investigate the pregnancy outcome of patients with preeclampsia (PE). Methods The data of 26 206 pregnant and lying-in women were retrospective analyzed who gave birth in Daping Hospital of the Army Medical University from Jan. 1, 2013 to Apr. 30, 2019, diagnosed with the 8th and 9th version of gynecology and obstetrics textbook. Excluding 62 cases of diabetes combined pregnancy, 445 cases of hypothyroidism combined pregnancy, 180 cases of polyhydramnios, 1592 cases of macrosomia (≥4 kg), 89 cases of chronic hypertension with PE, and 629 cases of multifetation. The remaining 23 209 cases, according to the final diagnosis, were divided into PE group (532 cases) which was divided again into mild-PE group (134 cases) and severe-PE groups (398 cases), and the 22 677 remainders acted as the control group. The age, gestational weeks, number of births, mode of delivery, pregnancy complications and neonatal status in the three groups were compared, and the thyroid function among the groups was analyzed in detail. Results The proportion of elderly parturients was higher in both mild-PE group (29.2%) and severe-PE groups (20.6%) than that in control group (12.4%). The rates of premature delivery and cesarean section were higher in both mild-PE group (19.7% and 55.0%) and severe-PE groups (70.1% and 94.2%) than those in control group (10.0% and 48.2%). The incidences of hypothyroidism during pregnancy, intrahepatic cholestasis of pregnancy (ICP) and infants younger than gestational age were higher in both mild-PE group (26.9%, 10.5% and 7.5%) and severe-PE groups (23.9%, 9.3% and 22.1%) than those in control group (17.5%, 3.5% and 2.9%); The incidences of placental abruption and stillborn foetus were obviously higher in severe-PE group (3.8% and 7.3%) than those in control group (0.6% and 0.7%). The incidence of gestational diabetes was significantly higher in mild-PE group (41.8%) than that in control group (30.0%), and of umbilical cord around neck was significantly lower in severe-PE group (17.6%) than that in control group (25.1%). Conclusions The incidences of complications and therapeutic premature delivery in PE patients is increased. Hypothyroidism during pregnancy is a potential risk factor and should be strenuously supervised.

OBJECTIVETo discuss the effect of taurine (Tau) on the proliferation of hypoxia-induced pulmonary artery smooth muscle cells (PASMCs), and study whether the extracellular signal-regulated kinase 1/2 (ERK1/2) signal pathway participated in the Tau-inhibited PASMC proliferation process and the possible molecular mechanism.

METHODThe primary culture was performed for PASMCs in rats. The second to fifth generations were adopted for the experiment. The Tau concentration was 80 mmol x L(-1). The concentration of ERK1/2 blocker (PD98059) was 50 micromol x L(-1). The drug administration time was 24 h. The effect of Tau on the PASMC proliferation was detected by MTT assay, immunofluorescence staining method and western blot under different conditions. The PASMCs were growing were divided into four groups: the normoxia group, the normoxia + Tau group, the hypoxia group and the hypoxia + Tau group. The Western blot was adopted to detect whether the ERK1/2 signal pathway participated in the Tau-inhibited PASMC proliferation process. Subsequently, the PASMCs were divided into five groups: the normoxia group, the hypoxia group, the hypoxia + Tau group, the hypoxia + Tau + PD98059 group and the hypoxia + PD98059 group.

RESULTHypoxia could induce the PASMC proliferation. Under the conditions of normoxia, Tau had no effect on the PASMC proliferation. Under the conditions of normoxia and hypoxia, Tau had no effect on the expression of the tumor necrosis factor-alpha (TNF-alpha) among PASMCs. Tau could reverse the expression up-regulation of hypoxia-induced proliferative cell nuclear antigen (PCNA) (P < 0.01) and Cyclin A (Cyclin A) (P < 0. 05). Under the conditions of normoxia, Tau had no effect on the expression of phosphoryl extracellular signal-regulated kinase 1/2 (p-ERK1/2). Hypoxia could up-regulate the p-ERK1/2 expression (P < 0.01). Tau could reverse the up-regulation of the hypoxia-induced p-ERK1/2 expression(P < 0.01). Both PD98059 and Tau could inhibit the up-regulated expressions of PCNA, Cyclin A and p-ERK1/2. According to the comparison between the single addition of Tau and PD98059 under conditions of hypoxia, the hypoxia + Tau + PD98059 group showed more significant down-regulation in the expressions of PCNA, Cyclin A and p-ERK1/2.

CONCLUSIONTau could inhibit the hypoxia-induced PASMC proliferation, and may regulate it through ERK1/2 pathway.

Objective · To estimate correlation between coronary artery calcification score (CaCS) and prognosis of peritoneal dialysis (PD) patients.Methods · The clinically stable patients who had undergone PD for at least 2 months were recruited for this prospective and observational cohort study.Coronary artery calcification was assessed by multislice spiral computed tomography and was recorded according to the Agatston score. The patients were assigned to 3 groups, i.e. no calcification group (CaCS=0), low calcification group (0

Objective To study the feasibility and indication of liver injury in children treated nonoperatively.Methods Ninteen(cases) with liver injury who underwent nonoperative management(NOM) were analyzed retrospectively.Patients with obvious trauma were reviewed.The main cause of trauma was due to traffic accident.Eleven cases(57.9%) had subcapsular hematoma and 8 cases(42.1%)had intrapararenchymatous hematoma.The treatment procedure included blood transfusion,hemostasis and monitoring the hemodynamic parameters.Results Seventeen cases(89.5%)were cured nonoperatively;2 cases underwent the operation later.Followed up for 10-24 months,patients were well recovered.Conclusions Most of cases with liver injury in children can be cured by NOM due to the physicalogical and anatomic features of children.During treatment,it is very important for the doctors to observe the vital signs closely,and(mana)-ge the combined injuries effectively and take regular imaging measurement.
