Objective:To explore value of plasma N terminal pro B type natriuretic peptide (NT-proBNP)assessing prognosis of patients With diastolic heart failure (DHF)complicated type 2 diabetes mellitus (T2DM).Methods:The folloW-up data of 206 inpatients With DHF and T2DM from our hospital Were retrospectively analyzed.Ac-cording outcome,they Were divided into no event group (n=108)and event group [n=98,With major adverse car-diovascular events (MACE)occurred].Levels of NT-proBNP,glycosylated hemoglobin (HbA1c),total cholesterol (TC)and loW density lipoprotein cholesterol (LDL-C),left ventricular end-diastolic dimension (LVEDd),left ventricular peak early diastolic velocity/peak late diastolic velocity (E/A)and left ventricular ejection fraction (LVEF)during admission Were measured and compared betWeen tWo groups. Results:Compared With no event group,there Were significant increase in NT-proBNP level and LVEDd,and significant decrease in LVEF and E/A in event group (P<0.05 all).Single factor linear analysis indicated that NT-proBNP,HbA1c,LVEDd and E/A Were positively correlated With MACE incidence rate (r=0.075~0.091,P<0.05 all).Mutivariate Logistic regres-sion analysis indicated that NT-proBNP Was an independent predictor for MACE (OR=1.003,P=0.009).Areaunder recieve operating characteristic curve (ROC)Was 0.803 for NT-proBNP predicting mortality of patients during admission (P <0.05),and survival rate of patientsWith plasma NT-proBNP≤4010pg/mlWas significantly higher than that of patients With NT-proBNP>4010 pg/ml (OR=5.028,P <0.05).Conclusion:Plasma NT-proBNP can independently predict prognosis of patients With diastolic heart failure complicated type 2 diabetes mellitus.

To explore the effects of Western medicine including Ca(2+) channel antagonist and angiotensin-receptor antagonist combined with Songling Xuemaikang Capsule (SXC), a compound traditional Chinese herbal medicine for calming liver and suppressing liver yang, on blood pressure indexes derived from 24-hour ambulatory blood pressure monitoring (ABPM), and to evaluate the effects and stability of SXC in lowering blood pressure.

Objective To discuss the relationship between repetitive variable deceleration with a short interval (RDSI) in labor and neonatal acidosis.Methods One hundred and seventy-seven electronic fetal heart monitoring (EFM) patterns within one hour preceding delivery in term singleton pregnancies were collected in Peking University Third Hospital between February 2011 to October 2013.Continued EFM were recorded before delivery.Analysis was conducted on general information of both mothers and babies,including pregnant complications,duration of labor,cord and placental factors,nature of amniotic fluid,Apgar score and neonatal cord blood gas.RDSI was defined as that over 50％ intervals between two decelerations (the end of the last deceleration to the beginning of the next one) ≤ 60 s which appeared repetitevly in a period of 20 minutes.Independent sample t test,rank sum test,Chi-square test and Fisher's exact test were applied for statistics and receiver operating characteristic curve was obtained from the information of those with RDSI.Results Twenty-four of the 177 women with RDSI were assigned to the study group (24 cases,13.6％) and the rest 153 cases without RDSI to the control group.Background information of women in the two groups was comparable according to the maternal age,gestational weeks at delivery and duration of labor (all P ＞ 0.05).The occurrence of meconium stained amniotic fluid in the study group was higher than that of the control group [16.7％ (4/24) vs 5.2％ (7/153),x2=5.204,P=0.045],while the pH and base excess value of the neonatal blood gas in the study group were lower [7.20 (7.13-7.28) vs 7.29 (7.25-7.33),Z=-4.490;-6.10 (-4.67 to-9.62) mmol/L vs-3.20 (-4.90 to-1.55) mmol/L,Z=-5.044;P ≤ 0.01] resulting a higher rate of neonatal acidosis [50.0％(12/24) vs 7.8％ (12/153),x2=31.456,P ＜ 0.01].No significant difference was found in the incidence of neonatal asphyxia between the two groups.The area under the curve was 0.774 (95％CI:0.579-0.969).Conclusion RDSI in labor might indicate a high risk of neonatal acidosis.

Objective To observe the effects of total flavone from litchi chinensis sonn (TFL) on the liver function in-cluding p16 protein, pro collagen type 3 (PC3) and pro collagen typeⅠ(PCⅠ) in model rats with liver fibrosis induced by bile duct ligation. Methods Forty rats were randomly divided into four groups:sham operation (SO) group, bile duct liga-tion (BDL) group, TFL group and silibinin (SIL) group. Rats were gavaged with saline (5 mL·kg-1·d-1) in SO and BDL group, rats were gavaged with TFL (200 mL·kg-1·d-1) in TFL group and rats were gavaged with SIL (5 mL·kg-1·d-1) in SIL group for four weeks. The serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin direct (BILD) and bilirubin total (BILT) were detected in four groups. The liver tissues were stained by HE and Masson methods. The ex-pression levels of p16, PC3 and PCⅠin liver tissues were determined by Western blot assay. Results The serum levels of ALT (44.6 IU/L±8.0 IU/L), AST (103.8 IU/L±18.1 IU/L), BILD (0.76 μmol/L±0.28μmol/L) and BILT (1.48μmol/L±0.35μmol/L) were lower in SO group. There was a higher level of ALT in BDL group (147.4 IU/L±86.3 IU/L) than that of TFL group (92.9 IU/L±47.3 IU/L). The serum level of ALT was higher in AST group (362.7 IU/L±106.6 IU/L) than that of TFL group (290.1 IU/L ± 171.7 IU/L) and SIL group (250.2 IU/L ± 54.9 IU/L). The serum level of BILD was lower in BDL group (99.71μmol/L±40.87μmol/L) than that of SIL group (137.01μmol/L±38.86μmol/L). The serum levels of BILD and BILT were significantly lower in TFL group (81.48μmol/L±47.50μmol/L, 106.64μmol/L±61.04μmol/L) than those of SIL group (P<0.05). There were small amount of new bile duct and no obvious cells degeneration, small amount of infiltration of in-flammatory cells and collagen deposition in TFL group. The liver fibrosis improved significantly in TFL group than that of BDL group. There were more new bile duct in hepatic portal area in SIL group than those of TFL group. The expression levels of p16, PC3 and PCⅠwere significantly higher in BDL group than those of TFL group. The expression level of PC3 was significantly lower in BDL group than that of SIL group. The expression level of PCⅠwas significantly higher in BDL group than that of SIL group (P<0.05). There was no significant difference in the expression level of p16 between BDL group and SIL group. The expression levels of PC16 and PC3 were significantly lower in TFL group than those of SIL group (P<0.05). There was no significant difference in the ex-pression level of PCⅠbetween TFL group and SIL group. Conclusion TFL can improve the liver function in model rats with choles-tatic liver fibrosis and reduce liver fibrosis, which may be related with inhibitory effects on the expressions of p 16, PC3 and PCⅠ.

Objective To investigate the effect of low dose of BDE209 on thyroid hormone and thyroid hormone metabolism enzyme-iodothyroninedeiodinases Ⅱ(D2) in off spring mice after pregnancy exposure .Methods Total 64 adult SPF female Kun-ming mice were randomly divided into 4 groups ,which treated with oral gavage of 0 ,50 ,100 ,300 μg · kg -1 · d-1 dose of BDE209 after successful pregnancy ,the exposure continue to 21 days after delivery .10 mice was randomly selected in each offspring group and get the peripheral blood and brain sample ,the serum thyroid hormones level ,oxidative damage and the expression of D2 mRNA in brain were detected .Results Compared with the control group(0μg · kg -1 · d-1 dose of BDE209) ,the TT4 ,TT3 ,FT4 and FT3 levels of offspring mice increased significantly in every exposure group (P< 0 .05);antioxidant enzyme glutathione-S transferees (GST) ,superoxide dismutase (SOD) activity decreased with the BDE209 dose increase (P<0 .05) ,and malondialdehyde (MDA) level increased (P<0 .05);the D2 mRNA relative expression of brain in middle(100μg · kg -1 · d-1 dose of BDE209) and high(300μg · kg -1 · d-1 dose of BDE209) dose group decreased when compared with control group (P< 0 .05) .Conclusion Low level of BDE209 exposure in pregnancy resulted in the increasing of thyroid hormone levels in offspring mice ,which may cause oxidative damage and decrease expression of D2 mRNA in the brain .

OBJECTIVE: To observe the effects of maternal low-level decabromodiphenyl( BDE209) exposure on nervous system and secretion of thyroid hormones in offspring mice. METHODS: Sixty-four specific pathogen free female,aged 4 weeks Kunming mice were used. These mice were randomly divided into control group and low,medium and high exposure groups after successful mating was confirmed. The rats of control group were fed with 0. 01 L/kg body mass of peanut oil.The maternal mice in the experimental groups were given BDE209 at doses of 50,100 and 300 μg/kg body mass by oral gavage once per day. Continuous exposure was given until 21 days after birth of offspring,the exposure model from gestation to lactation was established. At the end of the exposure,10 mice of each group including half female and half male were randomly selected and the body mass and growth development status were observed. Morris water maze was used to examine the learning and memory ability in offspring mice. The serum levels of total triiodothyronine( TT3),free triiodothyronine( FT3), total tetraiodothyronine( TT4) and free tetraiodothyronine( FT4) were measured by chemiluminescence immunoassay. The levels of glutathione transferase( GST), superoxide dismutase( SOD) and malondialdehyde( MDA) level in hippocampus were measured by colorimetry. RESULTS: The escape latency of the medium exposure group was longer than that of the control group( P < 0. 05). The escape latency of high exposure group was longer than that of control group,low exposure group and medium exposure group( P < 0. 05). The time of quadrant movement and number of crossing the platform in offspring rats in high exposure group were less than that of the control group and the low and medium exposure groups( P < 0. 05). The serum levels of TT3,FT3,TT4 and FT4 increased,the activities of GST and SOD in hippocampus tissue decreased,the MDA level increased with the increasing exposure dose( P < 0. 05).CONCLUSION: Maternal low-level BDE209 exposure can result in decrease the learning and memory ability of offspring mice. It also can increase the serum thyroid hormone level and induce oxidative stress injury in hippocampus in a dose dependent manner in offspring mice.
