Objective To explore left ventricular longitudinal axis systolic asynchrony by real-time triplane quanti-tativetissue velocity imaging(RT-3PE QTVI) and two-dimensional speckle tracking imaging(STI) in patients with dilated cardiomyopathy. Methods Thirty normal adults were included as the control group and thirty adults with DCM. The images from enough frame rates RT-3PE QTVI and STI were obtained from series long-axis views. Simp-son method was used to measure LVEF. Q-lab software was used to measure peak systolic tissue velocity(Vs) and peak systolic longitudinal strain (Ls),its time to peak point from each segment(Ts,Tls) and the maximal temporal difference of Ts,Tls(Ts-diff,Tls-diff),and the standard deviation of. Ts,Tls(Ts-SD,Tls-SD),which were served as systolic asynchrony indexes in assessing LV longitudinal axis systolic asynchrony. Results ① Compared the con-trol group and DCM group,there were significant differences in LVEDd,LVESd,LVEDL,LVESL,LVEF,FS (P<0.01). ② In comparison with the control group,the Ls and Vs of each segment were decreased in the DCM group (P<0.01). Compared with the control group,the parameters of Tls and Ts in DCM group had obvious ahead or de-layed(P<0.05). ③ Compared with the control group,the parameters of Ts-SD, Tls-SD, Ts-diff, Tls-diff,were significantly different in DCM group (P<0.01). Ts-SD,Tls-SD,Ts-diff,Tls-diff corrrlated negatively to LVEF(r=-0.67,-0.72,-0.75, -0.77,P<0.01). Conclusion The prevalence of left ventricular longitndinal axis systolic asynchrony exits in patients with DCM. There is a better technique to evaluate LV longitudinal axis systolic asynchrony by RT-3PE QTVI and STI than only one.

Objective To study the p53 gene mutation induced by organic extract of reclaimed water used in a city. Methods The organic extract of reclaimed water was collected by C18 solid-phase extraction (SPE) and the 16 kinds of polycyclic aromatic hydrocarbons (PAHs) in the reclaimed water were analyzed using gas chromatography-mass spectrometry (GC-MS). L-02 cells were treated with the organic extract of the reclaimed water at 0.84, 1.68, 3.34 ?l/ml for 24 h. DNA samples for p53 mutation detection was extracted from the cells and subjected to DNA sequencing for detection of mutations in exon 5 of the p53 gene. Results All 16 kinds of PAHs were detected both in input water and reclaimed water. The predominant ones were fluorene and phenanthrene,then naphthalene, acenaphthene, acenaphthylene, anthracene, fluoranthene, pyrene and so on. Total PAHs concentration was 1 777.9 ng/L in the input water and 1380.1 ng/L in the reclaimed water. Mutation in exon 5 within the p53 gene was detected in L-02 cells treated with the organic extract of the water. Conclusion PAHs in water can be removed by sewage treatment technology at present, but the remaining PAHs can still induce the mutation of p53 gene, so using reclaimed water has some potential health impacts, the sewage treatment technology employed today should be improved.

Objective To investigate the effect of renal dysfunction on the prognosis of hospitalized patients with decompensated heart failure (DHF).Methods 191 patients with DHF hospitalized between June 2011 and June 2013 in Baoshan Branch of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine were enrolled. These patients were divided into three groups according to the glomerular filtration rate (eGFR): normal renal function group (eGFR ≥ 90 mL·min-1·1.73 m-2, 63 cases), mild renal function descend group (eGFR 60 - 89 mL·min-1·1.73 m-2, 80 cases) and moderate or severe renal function descend group (eGFR < 60 mL·min-1·1.73 m-2, 48 cases). The general clinical data were recorded; the serum tumor necrosis factor-α (TNF-α) and interleukins (IL-1, IL-6, IL-8, IL-10, IL-13) were determined by enzyme-linked immunosorbent assay (ELISA). After discharge, the patients were followed-up for 1 year, and their outcomes were compared among the three groups.Results In 191 hospitalized patients with DHF, there were 67.0% with renal function impairment. Compared with normal renal function group and mild renal function descend group, the patients in moderate or severe renal function descend group were older (years: 83.4±5.1 vs. 66.2±5.4, 76.8±6.3), their cardiac functions were poorer, and their incidences of complications were higher than those in the normal renal function group [hypertension: 66.7% (32/48) vs. 42.9% (27/63), diabetes: 65.6% (31/48) vs. 41.3% (26/63), anemia: 37.5% (18/48) vs. 15.9% (10/63), acute myocardial infarction (AMI): 25.0% (12/48) vs. 9.5% (6/63), old myocardial infarction: 31.3% (15/48) vs. 11.1% (7/63), pulmonary infection: 29.2% (14/48) vs. 11.1% (7/63), allP < 0.05]. The complication incidences of hypertension [66.7% (32/48) vs. 51.3% (41/80)], diabetes [65.6% (31/48) vs. 48.8% (39/80)], anemia [37.5% (18/48) vs. 25.0% (20/80)] and pulmonary infection [29.2% (14/48) vs. 16.3% (13/80)] had no statistically significant differences between the moderate or severe renal function descend group and mild renal function descend group (allP > 0.05). The complication incidence of AMI [25.0% (12/48) vs. 10.0% (8/80)] and old myocardial infarction [31.3% (15/48) vs. 11.3% (9/80)] in moderate or severe renal function descend group was obviously higher than that in mild renal function descend group (bothP < 0.05). There were no statistically significant differences in the complication incidences of chronic obstructive pulmonary disease [COPD, 12.7% (8/63), 17.5% (14/80), 20.8% (10/48)], atrial fibrillation [30.2% (19/63), 27.5% (22/80), 29.2% (14/48)], ventricular premature beat [9.5% (6/63), 11.3% (9/80), 10.4% (5/48)] and cerebrovascular disease [20.6% (13/63), 22.5% (18/80), 22.9% (11/48)] among the three groups (allP > 0.05). Compared with normal renal function group, the levels of inflammatory cytokines in serum TNF-α, IL-1, IL-6, IL-8, IL-10, IL-13, and the mortality, the re-admission rates due to heart failure, rates of malignant arrhythmia in the two renal function descend groups were increased significantly, the increment being more remarkable in moderate or severe renal function descend group [TNF-α (ng/L): 235.8±20.9 vs. 121.6±10.7, IL-1 (ng/L): 345.9±40.8 vs. 203.5±34.7, IL-6 (ng/L): 502.8±64.2 vs. 321.9±53.8, IL-8 (ng/L): 723.9±210.3 vs. 431.5±110.5, IL-10 (ng/L): 155.4±23.5 vs. 103.1±13.2, IL-13 (ng/L): 184.5±27.3 vs. 136.8±20.2, the rate of mortality in the first time of hospitalization: 14.6% (7/48) vs. 5.0% (4/80), mortality within one year after discharge: 25.0% (12/48) vs. 18.0% (9/80), readmission rate due to heart failure: 47.9% (23/48) vs. 30.0% (24/80), rate of relapse of coronary events: 72.9% (35/48) vs. 37.5% (30/80), malignant arrhythmia rate: 39.6% (19/48) vs. 20.0% (16/80), allP < 0.05]. There were no significant differences in the rates of stroke among moderate or severe, mild and normal renal function descend groups [4.2% (2/48), 3.8% (3/80), 3.2% (2/63),P > 0.05].Conclusions The incidence of renal dysfunction in patients with DHF is relatively high, and their mortality, re-admission rate and their levels of inflammatory cytokines are high obviously. Thus, the intervention of renal dysfunction may have important significance in the improvement of their prognoses.

Objective To observe the impact of modified Liangge powder (MLP) on platelet activation markers and the release of proinflammatory cytokine in mice by stimulation of lipopolysaccharide (LPS). Methods 112 male mice were randomly divided into control group, model group and MLP low, middle and high dose treatment groups. The sepsis model was reproduced by injection of LPS 10 mg/kg into a mouse tail vein. In the control group, normal saline 10 mg/kg was injected into the tail vein of mouse. The MLP low, middle, and high dose groups received 0.94, 1.89, 2.84 g/mL MLP 0.02 mL/g by gavage respectively for 3 days, while the control group and model group received equal amount of normal saline by gavage for 3 days. After modeling for 24 hours and 72 hours, 8 mice in each of the three different dose MLP groups and model group were killed and their blood was taken. In the control group, after modeling for 24 hours, 8 mice were killed and their blood was taken. Platelet (PLT) was counted by blood cell analyzer, plasma interleukin-10 (IL-10), high mobility group protein B1 (HMGB1) and platelet factor 4 (PF4) were detected by enzyme-linked immunosorbent assay (ELISA). In each group after modeling for 72 hours, another 8 mice were taken, and laser scanning confocal microscopy was used to measure the platelet cytosolic Ca2+ concentration. Results Compared with the control group, the level of PLT at 24 hours(×109/L: 347.70±115.10 vs. 1 013.10±136.60) was decreased, and the levels of IL-10 (μg/L: 356.86±34.72 vs. 39.50±23.45), HMGB1 (mg/L: 16.24±4.49 vs. 10.75±1.91), PF4 (μg/L: 5.43±0.61 vs. 1.33±0.40) and Ca2+ (nmoL/L: 8.60±0.52 vs. 1.05±0.33) were elevated in model group. Compared with the model group, the levels of PLT in the MLP high, middle and low dose groups were all significantly elevated; the increase in PLT in middle dose group after modeling for 72 hours was the most remarkable (×109/L:952.13±104.02 vs. 771.50±129.30, P < 0.05); the levels of IL-10, HMGB1, PF4, Ca2+ in MLP low, middle, high dose groups were significantly decreased. The most obvious degree of decrease in level of the following indexes were as follows:IL-10 in MLP high dose group at 72 hours after modeling (μg/L:110.17±29.12 vs. 441.50±30.72), HMGB1 in MLP high dose group after modeling for 24 hours (mg/L: 10.33±3.52 vs. 16.24±4.49), PF4 in MLP middle dose group after modeling for 24 hours (μg/L:2.08±0.92 vs. 5.43±0.61) and Ca2+ in MLP high dose group (nmoL/L:2.97±0.96 vs. 8.60±0.52, all P<0.05). Conclusion MLP may possibly down-regulate the inflammatory cytokines release induced by LPS to inhibit the activation of platelet Ca2+, in turn prevent the activation of platelet and improve thrombocytopenia caused by LPS.

Objective To explore the serum levels of growth differentiation factor-15 (GDF-15) in patients with acute exacerbation of chronic heart failure (CHF) and its correlation with other common indexes,to provide reference for its clinical diagnosis,treatment and prognosis.Methods Two hundred patients with acute exacerbation of CHF were selected as CHF group,and 100 matched healthy volunteers were selected as control group.Serum levels of GDF-15 and N-terminal pronatriuretic peptide (NT-proBNP) were detected,and left ventricular end diastolic diameter (LVESD),left ventricular end diastolic diameter (LVEDD),and left ventricular ejection fraction (LVEF) were measured by echocardiography within 2 hours after admitted to hospital,and after the symptoms improved of CHF group,and on health examination day of control group.Patients in CHF group were followed up to record CHF related adverse events.Correlations between GDF-15 and other indicators were analyzed by Spearman correlation analysis,and the clinical value of serum GDF-15 on diagnosing CHF was analyzed by the receiver operating characteristic curve (ROC) and the area under the curve (AUC).Results The serum levels of GDF-15 and NT-proBNP in each time-point of CHF group were all higher than those of control group (t =4.70 ～ 7.11,P ＜ 0.05 orP ＜ 0.01).The serum levels of GDF-15 and NT-proBNP had negative correlation with LVEF (r =-0.539,-0.572,P ＜ 0.01),and had positive correlation with LVESD,LVEDD,and NYHA cardiac functional grading (r =0.505 ～ 0.861,P ＜ 0.01).Serum GDF-15 had positive correlation with serum NT-proBNP (r =0.528,P ＜0.01).With the increase of serum GDF-15 level,CHF group's readmission (rate) and death (rate) were both increased (x2 =36.86,26.59,P ＜0.01).AUC of predicting readmission risk by serum GDF-15 was 0.822 (95％ CI:0.719 ～0.890,P ＜0.01),and the best predictive cutoff point was 2 876.30 ng/L (sensitivity was 91.86％,specificity was 73.27％).AUC of predicting mortality risk was 0.816 (95％ CI:0.715 ～ 0.885,P ＜ 0.01),and the best predictive cutoff point was 3 487.05 ng/L (sensitivity was 91.72％,specificity was 69.05％).Conclusions Serum GDF-15 level in patients with acute exacerbation of CHF is higher,decreases with symptoms improvement,has positive correlation with LVESD,LVEDD,and NYHA cardiac functional grading,and has negative correlation with LVEF,has higher sensitivity on predicting CHF-related adverse events,and the mechanism may be related to the activation of SMAD pathway.Therefore,it may be a promising biomarker for clinical diagnosis and prognosis of cardiovascular diseases.

ObjectiveTo evaluate the effects of Esmolo on the hemodynamic and tissue oxygenation of the patients with septic shock and tachycardia.MethodsSeventy four septic shock patients with tachycardia were enrolled and randomized into Esmolo-treated group and control group after early goal-directed therapy (EGDT).The patients in Esmolo group were given intravenous Esmlol to decrease the heart rate to below 110 beats per minute.Hemodynamic data and tissue oxygenation parameters,such as Heart rate (HR),Mean Artery Pressure ( MAP),Central Venous Pressure ( CVP),Cardiae Index ( CI),Stroke Volume Index ( SVI),Systemic Vascular Resistance Index (SVRI),Lactate,Centrol Venous Oxygen Saturation (SCVO2 ) were recorded before and 2,3,4 hours after the Esmolol treatment.Results Heart rate of Esmolol group was reduced at all time points after treatment,The difference of that from the control group was significant ( H R: [ 108 ± 16 ] beats/min vs.[ 132 ± 18 ] beats/min,[ 101 ± 14] beats/min vs.[ 135 ± 19 ] beats/min,[ 106 ± 21 ] beats/rin vs.[ 129 ± 14]beats/min,all P ＜ 0.01 ).Compared to the control group,Stroke Volume Index of Esmolol group was significantly increased at each time point ( SVI: [32 ± 12] ml/m2 vs.[22 ±8] ml/m2,[34 ± 14] ml/m2 vs.[21 ±6] ml/m2,[37 ± 10] ml/m2vs.[23 ±9] ml/m2,all P ＜0.05).Lactate of Esmolol group was significantly decreased at the end of the 3rd,4th hour of Esmolol treatment ( lactate: [ 1.6 ± 1.1 ] mmol/L vs.[ 2.7 ± 1.2 ]mmol/L,[ 1.3 ± 0.9 ] mmol/Lvs.[ 2.8 ± 1.4 ] mmol/L,both P ＜ 0.01.There were no significant differences in MAP,CI,SVRI,SCVO2 between the two groups at each time point ( all P ＞ 0.05 ).Conclusion Esmolol can reduce heart rate significantly,improve cardiac work and tissue perfusion in septic shock patients with tachycardia.It is a feasible and safe treatment for this kind of patients.
