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 explore the effect of Valpar occupational assessment training system on cognitive dysfunction in schizophrenia. Methods Sixty patients with schizophrenia were randomly assigned into Valpar therapy group ( experiment group, n=30) and traditional rehabilitation therapy group ( control group, n=30) according to the order number. The duration of the treatment was six weeks. The brief assess?ment of cognition in schizophrenia ( BACS) and Wisconsin card sorting test ( WCST) were conducted as pre?and post?treatment assessment. Results There were significant differences between scores of BASC in pre?and post?treatment assessment in experiment group. More specifically, the BASC scores in symbol coding (37.50±6.50, t=-4.60, P<0.01),token movement(60.80±8.72, t=-2.54, P=0.017),verbal memory (44.40±11.29, t=-2.19, P=0.037)),and word fluency(14.23±4.35, t=-3.39, P=0.002) were signifi?cantly different when comparing pre?and post?treatment assessment outcomes. In control group,the only sig?nificant difference was found in word fluency (14.23±4.35, t=-3.39, P=0.002).In addition,response errors (57.80±10.35, t=-3.06, P=0.005) and repeat errors (34.67±6.96, t=3.41, P=0.002) in WCST in exper?iment group were significantly different in pre?and post?treatment assessment while only repeat errors (34.30 ±7.01, t=4.36, P=0.000) was different in control group. It was further discovered that scores in in symbol cod?ing( t=2.010, P=0.048),token movement ( t=2.124, P=0.038),response errors ( t=2.413, P=0.020) and repeat errors( t=2.009, P=0.047) in WCST were different between two groups. Conclusion Valpar professional evaluation train?ing system can significantly improve the cognitive function of people with schizophrenia.

Objective To study the neuroprotective effects of erythropoietin on intracerebral hemorrhage (ICH). Method The rat models of 1CH were produced by injecting autologous blood into caudate necleus by using stereotatic techique. One hundred ten male wistar rats were randomly divided into 4 groups, namely normal group,sham operation group, 1CU group, and EPO treatment group. The immunohistochemistry and TUNEL were used to detect expressions of Bc 1-2 and Bax,and apoptosis cells. LSD- t and Pearson correlation were used to analyzing data. Results The positive cells of TUNEL Bcl-2 and Bax in ICH group and EPO group obviously increased over 6 hours,and reached peak 72 hours later,and decreased over 120 hours,and the positive cells in different intervals significantly decreased in ICH group and EPO group compared with those in sham operation group (P < 0.01). The positive cells of TUNEL and Bax in EPO group in different intervals significantly decreased compared with those in ICH group (P < 0.01). The Bcl-2 positive cells in EPO group in different intervals significantly increased compared with those in ICH group (P < 0.01). The Bax protein expression, Bax/Bcl-2 and apoptosis presented positive correlation (P < 0.01). Conclusions Apoptosis may induce some brain injury after ICH,and EPO can decrease the number of apoptotic cells after ICH by up-regulating Bcl-2 and down-regulating Bax.
