Objective To describe the depression of premature infants′ mothers and discuss the related influence factors. Methods A total of 86 premature infants′ mothers completed Edinburgh Postnatal Depression Scale at 3-days postpartum in this descriptive study during August 2014 to January 2015 in Obstetrics and Gynecology Hospital of Fudan University. Results The prevalence of postpartum depression in premature infants′ mothers was 25.6% (22/86). Educational levels, family support, character, and number of abortion of mothers, pregnancy complication, gestational age, birth weight, Apgar score, length of hospitalization, and birth with abnormalities of premature infants were found significantly associated with postpartum depression (P<0.05). By Logistic regression, family support (OR=3.253, 95% CI=1.180-8.966) and length of hospitalization (OR=2.905, 95% CI=1.418-5.952) were the risk factors of the postpartum depression at 3-days after delivery. Conclusions Premature infants′mothers at 3-days postpartum presented with obvious postpartum depression. Psychological intervention should be focused on its influence factors.

Objective To study the interrelation between highly pathogenic avian influenza viral pneumonia(HPAIVP) and cellular factors interleukin-1?(IL-1?),interleukin-6(IL-6),interleukin-8(IL-8)and tumor necrosis factor-?(TNF-?) in HPAIVP.Me-thods Sixty Kunming mice were divided into 2 groups randomly:experiment group and control group,each group consisted of 30 mice.The highly pathogenic avian influenza virus was used to establish HPAIDP models.The expressions of serum IL-1?,IL-6,IL-8 and TNF-? in experiment group of different moment and control group were detected by enzyme linked immunosorbent assay(ELISA).Result The levels of serum IL-1?,IL-6 and TNF-? in experiment group were significantly higher than those in control group(Pa

Objective To explore the correlation between B lymphocyte activation and CD154 expression and lupus anticoagulants (LAC) in patients with systemic lupus erythematosus (SLE). Methods Sixty newly diagnosed SLE patients (SLE group) and 32 healthy controls (control group) were involved. The expressions of CD27 and CD154 in peripheral blood were determined by flow cytometry, and the positive expression rates were computed. The LAC was determined by activated partial thromboplastin time, and the LAC ratio > 1.20 was positive. Results The positive rate of CD27, expression intensity of CD27, positive rate of CD154 and expression intensity of CD154 in SLE group were significantly higher than those in control group: 0.047 ± 0.021 vs. 0.035 ± 0.014, 0.387 ± 0.185 vs. 0.214 ± 0.091, 0.191 ± 0.108 vs. 0.101 ± 0.081 and 0.049 ± 0.018 vs. 0.022 ± 0.012, and there were statistical difference (P<0.05 or <0.01). Among patients with SLE, the LAC positive was in 28 cases, and the LAC negative was in 32 cases. The positive rate of CD27, expression intensity of CD27, positive rate of CD154 and expression intensity of CD154 in SLE patients with LAC positive were significantly higher than those in SLE patients with LAC negative: 0.055 ± 0.023 vs. 0.037 ± 0.014, 0.444 ± 0.179 vs. 0.329 ± 0.123, 0.218 ± 0.101 vs. 0.158 ± 0.044 and 0.058 ± 0.035 vs. 0.020 ± 0.009, and there were statistical differences (P<0.05). Conclusions The B lymphocyte activation and CD154 abnormal expression correlates with generation of LAC in patients with SLE. It provides a basis for the further study on intervening the generation of LAC and reducing the risk of thromboembolism.

Objective To study the Val247Leu and Trp316Ser polymorphisms of β2-glycoprotein Ⅰ(β2GPⅠ) in systemic lupus erythematosus (SLE) patients and their associations with antiphospholipid antibodies and thrombotic complications.Methods We used DNA sequencing to detect the polymorphisms of Val247Leu and Trp316Ser in 378 SLE patients and 240 normal controls.Anti-β2GP Ⅰ antibodies and anticardiolipin (ACA) were tested by enzyme linked immunosorbent assay (ELISA).Lupus-type anticoagulants(LAC) was performed by diluted Russell's Viper Venom Test.Then the patient group was further analyzed according to APLs (Anti-β2GP Ⅰ antibody,LAC and ACA),thrombosis and obstetrical complications using Logistic regression analysis to confirm whether there are associations between β2GPⅠpolymorphism and those factors.Results For Va1247Leu,the predominant genotype was LL in healthy controls which accounted for 57.08％,while it was VL in SLE patients which accounted for 59.5％ (x2=45.01,P=0.000).Frequency of VV genotype was significantly higher in patients with thrombosis,anti-β2GP Ⅰ,ACA and obstetrical complications (OR=6.79,3.75,2.12 and 3.85,respectively;P=0.000,0.001,0.044 and 0.017,respectively).Those patients with VL genotype tended to have positive anti-β2GPI,LAC,ACA,thrombosis and also obstetrical complications (OR=2.95,1.88,2.47,2.97 and 2.74,respectively;P=0.000,0.007,0.000,0.001 and 0.016,respectively) than those negative ones.The predominant genotype of Trp316Ser was TT,then TS.No correlations could be found between Trp316Ser polymorphism and APLs,neither relation to thrombosis complications.Conclusion The polymorphism of Val247Leu is significantly associated with the presence of APLs,thrombosis and obstetrical complications.Both VV and VL genotype are risk factors for the generation of APLs,occurrence of thrombosis and obstetrical complications.The VV genotype is a high risk factor for thrombosis.Trp316Ser polymorphism does not contribute to the APLs production and also have no correlations with thrombotic complication.

In this study we implanted magnetically labeled neural stem cells (NSCs) in PD rats and then monitored their survival and migration in the host brain by magnetic resonance imaging (MRI). The mesencephalic NSCs were obtained from the brain of SD rats. Superparamagnetic iron oxide (SPIO) was transferred to NSCs by Lipofectamine transfection. Eighteen PD lesioned rats were selected for transplantation by evaluation of their rotational behavior in response to amphetamine and randomly assigned to 3 groups, i.e., sham group, PBS group and NSCs transplanted group, with 6 rats in each group. MR scanning was performed at 1, 2, 4, 6, 8 and 10 week(s) following transplantation. At the meantime, rotational behavior was assessed in each group. Our results showed that SPIO particles were clearly visible with Prissian blue staining in neurospheres and cells derived from NSCs. The rotational behavior of the NSCs transplanted group was remarkably improved compared with that of sham group and PBS group (P < 0.05). In vivo MR tracking of NSCs showed that SPIO labeling led to a strong susceptibility change of signal 1 week after transplantation on T2 weighted images. And a large circular hypointense signal appeared in the transplanted area on T2* gradient echo images. Ten weeks following transplantation, the hypointense signal on T2 weighted and T2* gradient echo images was still displayed. It is concluded that SPIO particles could label NSCs effectively, and MRI detection of SPIO labeled cells is a promising method and novel approach to analyzing the NSCs following transplantation in the treatment of PD.

Epidemiological,experimental and clinical studies had demonstrated the affinity between the development of tumor and prostaglandin E2 (PGE2).The level of PGE2 was elevated in tumor tissues and the relation was detected between PGE2 and the tumor size,tumor stage,metastasis,prognosis as well as reoccurrence.Thus,using inhibitors and detecting level of PGE2 play a vital role in the prevention and clinical treatment of tumors.

AIM: To investigate the effects of prenatal stress (PS) on neurons and neuronal ultrastructure of hippocampus in offspring rats, and to explore the role of the overproduction of oxidants. METHODS: One month male offspring rats were obtained to observe the neuronal number, neuronal ultrastructure and the number of nNOS -positive cell in hippocampus. RESULTS: The neuronal number of CA1 and CA4 subregions in late gestation stress (LS) offspring decreases significantly. The neuronal ultrastructure of CA1 subregion in MS (stress in 7-13 days of gestation) and LS offspring appeared bulgy mitochondria, unclear membrane and irregular electron density. Lipofuscin pigments increased; The number of nNOS-positive cell in CA1, CA2, CA3 subregions and DG of MS group and the whole hippocampus of LS group increased significantly. CONCLUSION: PS damaged the neurons and neuronal ultrastructure of hippocampus of offspring rats. The damages were associated with the overproduction of oxidants.
