Objective: To investigate the factors that affect the outcome of pregnancies complicated with critically heart disease admitted to obstetric Intensive Care Unit (ICU). Methods: A retrospective study was conducted for 188 pregnant and postpartum patientscomplicated with heart disease who were admitted to the ICU in West China Second University Hospital from July 2009 to March 2013. Results: During the 4 years, there were 619 cases of pregnancy complicated with heart disease hospitalization. Among them, 188 (30.37%) patients complicated with severe heart disease were admitted to the ICU, accounting for 39.17% of the total ICU admission (480); the mean maternal age was (28.45±6.08) years old and the mean gestational time was (36.03±4.19) weeks. 23 (12.23%) patients received regular antenatal care in our hospital. 61 (32.45%) patients never received antenatal care before hospitalization. Among them, 5 patients were dead. hTe ratio for diagnosis of heart disease before pregnancy, during pregnancy and atfer admission were 39.89%, 25.54% and 34.57%, respectively; the most common heart diseases during pregnancy were congenital cardiac disease (80, 42.55%) and rheumatic heart disease (45, 23.94%) followed by arrhythmias (20, 10.64%). The most common complication were pulmonary arterial hypertension (51, 27.13%), arrhythmias (47, 25.00%) and severe heart failure (30, 15.96%); the cardiac function of 164 (87.23%) patients was at stage I–II and 5 (2.66% ) patients died when discharged from hospital. 151 (80.32%) patients received multidisciplinary consultation and 34 (18.09%) used central venous catheterization to control central venous pressure (CVP). 21 (11.17%) patients required mechanical ventilation. 11 (5.85%) patients required emergency life support (cardiopulmonary resuscitation 9 + electric deifbrillation 3). Conclusion: Pregnancy complicated with heart disease is the leading reason for admission to ICU. hTe congenital cardiac disease, rheumatic heart disease and arrhythmias are the main heart diseases during pregnancy. Multidisciplinary cooperation and intensive care are the key measures to improve the outcomes of patients with critically illness. It is very important for reduction of the maternal mortality rate through strengthening preconception care and antenatal care.

ObjectiveTo explore the influences of age and duration of status convulsivus (SC) on mitochondrial membrane potential (△Ψm) in hippocampus. MethodsConvulsive seizures for 30 min or 3 h (30 min SC or 3 h SC) were induced in 80 infant (20 d after birth) and 80 adult Wistar rats (IRs & ARs respectively) with lithium-pilocarpine ip. The rats were sacrificed at 6 different time points from the 3rd hour to 7th day after SC termination. The mitochondrial △Ψm in hippocampal cells was determined with flow cytometry. ResultsThe mitochondrial △Ψm in hippocampal cells started to decrease at the 3th hour after SC in both IRs and ARs. The bottom level was reached at the 6th hour after SC [(6.08±0.43) in IRs and (5.70±0.63) in ARs ) ]. Both of them were significantly lower than that of control group (P<0.01) and began to increase at 12th hour after SC. On the 7th day after 30 minutes SC, the level of mitochondrial △Ψm in IRs increased to the level of control, while the level in ARs was still lower than that of control (P<0.05). At the 3rd hour, the 3rd and the 7th day after SC, the levels of mitochondrial △Ψm in IRs were obviously higher than those in ARs. Compared with the same time point after 30 min SC, the levels of mitochondrial △Ψm at the 3rd and the 6th hour after 3 h SC were much lower in different age groups (P<0.05). Except the effect of the age-related difference, there was a positive correlation between the duration of SC and the changes of mitochondrial △Ψm in partial correlation analysis (r=0.71,P<0.05). ConclusionSevere seizure could induce the mitochondrial △Ψm decreased in hippocampus. Age and duration of SC were important factors associated with the mitochondrial △Ψm decrease. There may be an internal protective response against brain damage in premature brain.

Objective To explore the effects of brain-derived neurotrophic factor (BDNF) on expression of apoptotic regulated genes (bcl-2 and c-jun) in hippocampus after status convulsivus (SC). Methods Seizures were induced in 32 adult Wistar rats with lithium-pilocarpine intraperitoneal injection (SC), the other 32 rats were as the normal controls (NC). The rats were sacrificed 6 h after injection of normal saline (NS), BDNF, or anti-BDNF in left lateral ventricle (or no injection). The expression of Bcl-2 and c-Jun protein and bcl-2 and c-jun mRNA were investigated with immunocytochemistry, RT-PCR and in situ hybridization. Results The expression of bcl-2 and c-jun (both protein and mRNA) was not significantly different in the hippocampus of both side in NC. In SC, the expression of bcl-2 ranged from more to less as BDNF>NS and non-injection>anti-BDNF in the hippocampus of non-injected side, while the expression of c-jun reversed. However,there was not significant difference in the expression of bcl-2 or c-jun in the hippocampus of non-injected side. Conclusion Exogenous BDNF can up-regulate the expression of bcl-2 and down-regulate the expression of c-jun in hippocampal cells, which may protect brain from apoptosis after after SC. The intraventricular injection of BDNF diffuses limited, which works less for clinical treatment.

Objective To explore the effect of the exogenous phosphorylation cyclic adenosine monophosphate response element bind-ing protein (pCREB) antibody on the expression of apoptotic regulated genes (Bcl-2 and c-Jun) in hippocampus after status convulsivus (SC), to elucidate the role and regulation mechanism of pCREB in convulsive brain injury. Methods Seizures were induced in 24 adult Wi-star rats with lithium-pilocarpine intraperitoneal injection (SC group), another 24 rats were as the normal controls (NC group). Each group was divided into no injection subgroup, normal saline injection subgroup and anti pCREB subgroup according to the injection contents of lat-eral ventricle, with 8 cases in each group. They were sacrificed 6 hours after injection. Both the protein and mRNA expression of Bcl-2 and c-Jun in bilateral hippocampus were detected by immunohistochemistry and in situ hybridization, respectively. Results There was no signifi-cant difference in Bcl-2 protein/mRNA expression among 3 subgroups in the NC group (P>0.05). In the SC group, the expression of Bcl-2 protein/mRNA were lower in the anti pCREB subgroup than in the no injection subgroup and normal saline injection subgroup (P<0.05). There was significant difference in c-Jun protein/mRNA expression among 3 subgroups in both NC group and SC group (P<0.001). The ex-pression of c-Jun protein/mRNA was higher in the normal saline injection subgroup and the anti pCREB subgroup than in the no injection group (P<0.05), especially in the anti pCREB subgroup (P<0.05). Conclusion Exogenous anti-pCREB antibody can down-regulate the ex-pression of Bcl-2 and up-regulate the expression of c-Jun in hippocampal cells after SC.

Objective To observe the effects of early exercise on the expression of synaptophysin pro-tein and Nissl bodies in the hippocampus after hypoxic-ischemic brain damage( HIBD) , and to investigate possi-ble mechanisms. Methods A total of 35 neonatal Wistar rats aged 7 days were randomly divided into a train-ing group of 13, a control group of 11 and a sham-operation group of 11. HIBD was induced in the rats of the training and control groups, while those in the sham-operation group had the left common carotid artery separa-ted, but without ligation. Seven days after successful modeling, the training group began swimming training for 10 min every day lasting for 14 days, while the other groups were not trained. Western blotting was used to detect the expression of synaptophysin in the affected hippocampus of the brain based on the ratio of the gray band val-ues for synaptophysin and beta. Nissl staining was applied to observe the number of Nissl bodies and the morphol-ogy of the neurons in the hippocampus. Results The average expression of synaptophysin in the sinistrocere-bral hippocampus of the rats in the control group was significantly lower than that in the sham-operation group, but significantly higher than that of the training group. The control group had significantly fewer Nissl bodies than the sham-operation group, but significantly more than the training group. Conclusion Early training can in-crease the expression of synaptophysin and the number of Nissl body in the hippocampus after hypoxic-ischemic brain damage.
