Objective: To observe the histomorphology/pathology changes and the expression of hypoxia inducible factor-1 alpha (HIF-1?) and vascular endothelial growth factor (VEGF) in drowning rats brain, in an attempt to explore new pathways for treatment of water drowning. Methods: The animal model of freshwater drowning was established with rats. The rats were randomly divided into the following groups: control group, drowning-to-death group and 2 min-drowning group (including 5 subgroups survived for 3, 6, 12, 24. and 40 hours after being drowned in water for 2 min [n=10]). Brain indices of rats in each group were detected and the pathological changes of cerebral tissues were observed; the expression of HIF-lo and VEGF were detected immunohistochemically and the correlation between them was analyzed. The dynamic blood oxygen saturation was detected in rats survived for 40 h after 2 min-drowning at different points. Results: Brain index of the drowning group and groups surviving for 24, 40 hours after drowning were obviously higher than that of the control group (P

OBJECTIVE:To study the effect of different administration time of ibuprofen on the changing characteristics of circadian rhythm about body temperature and plasma concentration in rats.METHODS:60 rats were given single oral administration of ibuprofen at the dose of 50 mg per kilogram at different time(2∶00,6∶00,10∶00,14∶00,18∶00,22∶00) according to a randomized block design with another 10 rats serving as blank control.The effects of ibuprofen on circadian rhythm variations of body temperature and plasma concentration in rats were observed and analyzed using chronogram and cosine method.RESULTS:The body temperature of rats prior to and after administration both showed a significant circadian rhythm,with mean declined only,yet acrophase and amplitude showed no significant differences.The best cosinor curve equation were Yt i=38.7+0.52 Cos(15??ti—86.80?) and Yt i=37.8+0.55 Cos(15??ti—117?) respectively.The plasma concentration also showed a significant circadian change in rats at the different time points of administration.The plasma concentration in light phase was higher than that in dark phase,and the best cosinor curve equation was Yt i=41.95+5.30 Cos(15??ti—272.83?).CONCLUSION:The differences of circadian rhythm were both shown about body temperature and plasma concentration in rats when ibuprofen was orally administered at the different time points.

Objective To investigate the effect of pregnancy management of gestational diabetes mellitus (GDM) on pregnancy outcome.Methods One hundred and two patients of GDM was as our case group and 100 patients with non-diabetic and no medical complications in pregnant women in the same period were as control group who all hospitalized from January 2008 to December 2011.The information of maternal and prenatal complications were collected.Results Pregnancy women were underwent the pregnancy management.No significant difference was seen in terms of the incidences of pregnancy induced hypertension polyhydramnios,preterm delivery,premature rupture of membranes and postpartum hemorrhage between case group and control group(x2 =1.33,0.80,0.68,0.35,0.20,respectively,P ＞ 0.05),so were other indices including of the incidences of fetal macrosomia,fetal distress,neonatal asphyxia,hyperbilirubinemia and neonatal hypoglycemia between the two groups(x2 =0.09,0.23,0.15,0.15,0.49,respectively,P ＞0.05).Conclusion Enhancing the management and standardized treatment of GDM can control the level of serum glucose and decrease the maternal and prenatal complications.

ObjectiveTo study the changes and clinical significance of serum heart-type fatty acid-binding protein (H-FABP) and soluble ST2 protein (sST2) in children with chronic heart failure (CHF).MethodsThirty-nine children with CHF and 30 healthy children were recruited. Serum levels of H-FABP and sST2 were determined by ELISA, The left ventricular ejection fraction (LVEF) and fractional shortening of the left ventricle (LVFS) were measured by two-dimensional echocardiog-raphy.ResultsIn 39 children with CHF, 15 males and 24 females, aged 2 months to 14 years, included 27 cases of endocardial ifbroelastosis (EFE) and 12 cases of dilated cardiomyopathy (DCM). According to the cardiac functional grading standard, the children with CHF were divided into 10 cases with cardiac function II, 15 cases with cardiac function III, and 14 cases with cardiac function IV. The mean levels of H-FABP, sST2 and NT-Pro-BNP in children with CHF at stage of heart failure and heart failure remission were statistically higher than those in the healthy children (allP<0.01). The serum H-FABP and sST2 levels had signiifcant differences among groups grouped according to cardiac functional grading standard (allP<0.05). The serum H-FABP and sST2 levels had no signiifcant difference between the EFE and DCM groups (allP>0.05). The Spearman correlation analysis showed that, in children with CHF at stage of heart failure, the serum H-FABP level was positively correlated with NT-Pro-BNP, sST2 and cardiac function (r=0.402、0.621、0.644,P<0.05). Serum sST2 level was positively correlated with NT-Pro-BNP and cardiac function (r = 0.501、0.678,P<0.05), and was negatively correlated with LVEF and LVFS (r=?0.340、?0.329, P<0.05).ConclusionsH-FABP and sST2 are involved in the development of heart failure. H-FABP and sST2 can be used as reference indices for clinical diagnosis and assessment of CHF.

CD+4 CD+25 regulatory T cell (Treg) has immune incompetent and immune suppression functions, and is a kind of suppressor T-cell subsets. It can inhibit the activation and proliferation of CD+4 T cells and CD+8 T cells, so as to effectively suppress the immune system to foreign organ and reduce the graftversus-host disease (GVHD) after hematopoietic stem cell transplantation (HSCT), without affecting the role of graft-versus-leukemia (GVL), which plays an important role in the transplantation immune tolerance.
