OBJECTIVE:To observe the clinical efficacy of recombinant human brain natriuretic peptide (rhBNP) combined with levosimendan in acute decompensated heart failure(ADHF). METHODS:In retrospective study,120 cases diagnosed as AD-HF were divided into observation group and control group according to treatment plan,with 60 cases in each group. The patients of control group received rhBNP on the basis of conventional treatment,intravenously pulsed with dose of 0.15 μg/kg firstly,then maintained dose of 0.007 5 μg/kg viacontinuous intravenous pumping for 24-72 h;On the basis of control group,treatment group received levosimendan with loading-dose of 12 μg/(kg·min)for 10 min,maintenance dose of 0.1 μg/(kg·min)via intravenous pump,for 24 h,adjusted according to clinical manifestations of patients. The vital signs,hemodynamic and UCG indexes,the rate of dyspnea recovery,plasma level of BNP,urine and the occurrence of ADR were recorded in 2 groups. RESULTS:The vital sign and hemodynamic indexes of control group had no significant change 1 h after treatment;the levels of HR,RR,SBP,MPAP and MPCWP in 2 groups after treatment were significantly lower than before,while the levels of SaO2 and CO were significantly higher than before,with statistical significance (P<0.05). The levels of HR,RR,SBP,MPAP and MPCWP in observation group 1,2, 4 h after treatment were significantly lower than in control group,while the levels of SaO2 and CO were significantly higher than control group,with statistical significance (P<0.05);there was no statistical significance in vital sign and hemodynamic indexes between 2 groups at other time points (P>0.05). 48 h after treatment,LVEF of 2 groups were increased while plasma levels of BNP were decreased,compared to before treatment;the improvement of observation group was more significant than control group,with statistical significance(P<0.05). And the urine volume of observation group were significantly higher than that of con-trol group 24,48 h after treatment,with statistical significance(P<0.05). There was no statistical significance in the rate of dys-pnea recovery at different time points and the incidence of ADR after treatment between 2 groups (P>0.05). CONCLU-SIONS:rhBNP combined with levosimendan could effectively improve vital sign,hemodynamic indexes,UCG indexes and dys-pnea,and decrease the plasma level of BNP with good safety.

Platelet aggregation rate (Pagt) and pletelet adhesion rate (PADT) were also measured. Results The platelet count in non-pregnant, late pregnant and HDCP group were (206?48)?109/L, (204?52)?109/L and (172?51)?109/L, respectively, and that in the HDCP group was significantly lower than the other two. The levels of GMP-140, TXB_2, ?-TG, PAdT and PAgT were (7.9?2.8) ?g/L, (73.6?40.8) ng/L, (16.3?9.5) ?g/L, (18?9)% and (28?10)% in the non-pregnant group, (12.2?3.8) ?g/L, (80.0?39.6) ?g/L, (18.5?9.8) ?g/L, (20?8)% and (29?10)% in the late pregnant group and (25.1?3.8) ?g/L, (107.6?32.8) ng/L, (23.9?9.2) ?g/L, (30?10)% and (40?12)% in the HDCP group. All the above values in the HDCP group were significantly higher than those in the other two groups (P

Conclusion The powder of G.lucidum has the effective antimicrobial activity and antioxidant activity.The two kinds of extracts extract of G.lucidum had good antibacterial activity and antioxidant activity.The ethanol extract of G.lucidum powder antimicrobial effect and total antioxidative ability in water extracts, aqueous extract of Ganoderma lucidum granules on DPPH free radical scavenging rate better than that of ethanol extract.

Objective To detect the expression of DBC2 and the methylation status of its gene promoter region in gastric cancer,so as to analyze their correlation. Methods Gastric cancer tissues and adjacent normal tissues were collected from 92 cases as research subjects. The DBC2 mRNA expression and the methylation status of DBC2 gene promoter region in gastric cancer were detected by using RT?PCR and MS?PCR respectively. In addition,the correlation of DBC2 gene methylation status with clinicopathological parameters was analyzed. Results In comparison with adjacent normal tissues,gastric cancer tissues displayed a low expression level of DBC2mRNA and a high methylation level of gene promoter region. Besides, the methylation level was significantly correlated with tumor invasion depth,differentiation and TNM staging(P<0.05). With deep invasion,poor differentiation or higher TNM staging,methylation level of gene promoter region was more significant in gastric cancer tissues. Conclusion High methylation of DBC2 gene promoter region may be a significant contributing factor leading to low DBC2 expression.

Objective To explore the effect of Acanthopanax senticosus injection (ASI) on brain multi-infract dementia rats. Methods Thirty-six male Wistar rats were randomly divided into 3 groups:control group, model group and ASI group. The multi-infract dementia rat models were set up by injecting mini-sludged blood in carotis internal arteries, learning and memory function of rats were determined by Morris water maze and Step-down test, the section of rat cerebral cortex and hippocampus were stained with haematoxylin eosin (HE). Results Compared with model group, latency in ASI group shortened significantly at 2nd,5th and 6th day, the distance shortened at 1st,2nd,5th and 6th day. The seeking tactics of ASI trgated rats improved in the Morris water maze test. The error times of ASI treated rats decreasd at 1st and 2nd day in Step-down test; ASI did not reduce significantly pathological changes of vascular dementia rats. Conclusion ASI has effect of treatment on multi-infract dementia rats.

Objective To explore the mechanism of therapeutic effect of Donepezil hydrochloride on Alzheimer's disease(AD) rats.Methods According to weight,36 rats were divided into normal group,model group and Donepezil hydrochloride group.AD rat model was set up by injecting D-galactose into abdominal cavity for seven weeks,learning and memory function of rats was determined by using Morris water maze and Step-down test.The section of rat cerebral cortex and hippocampus were stained with haematoxylin eosin(HE),and the effect of Donepezil hydrochloride was observed by detecting the MDA content and SOD activity in cerebral tissue.Results Compared with model group,latency and distance of Donepezil hydrochloride rats shortened on the fourth day and the fifth day,starting angle of Donepezil hydrochloride rats shortened on the fourth day and the fifth day in the Morris water maze test,error times of Donepezil hydrochloride rats decreased on the first day and the second day in Step-down test;MDA content in cerebral tissue of Donepezil hydrochloride rat was deceased(P

Objective To study the reversal effect of tetrandrine (TET) on the multidrug resistance of Hep-2/ADM cell line and the possible mechanisms. Methods MTT method was used for the detection of the inhibitory effect of different concentrations of TET on the multidrug resistance of Hep-2/ADM cell line for selection of the non-toxicity concentration. MTT reduction assay was used to investigate the drug interaction of TET and vincristine (VCR) on HNE-1 (200) cell line. The reversal index (RI), accumulation and excretion of drug, and the apoptosis of Hep-2/ADM cell line were detected by flow cytometry. Results No toxicity to Hep-2/ADM cell line was found when TET concentration was lower than 1.5 ?g/ml. After interaction with TET (1.0 ?g/ml and 1.5 ?g/ml), RIs of VCR on Hep-2/ADM were 1.72 and 2.00 folds, respectively. TET at the concentration of 1.5 ?g/ml could increase the drug excretion and accumulation and also the apoptotic rate of VCR-induced Hep-2/ADM cell line. Conclusion TET can reverse the multidrug resistance of Hep-2/ADM cell line. The reversal effect may be related to the concentrations of TET. The possible mechanism may be that TET can increase the cell apoptosis of VCR-induced Hep-2/ADM cell line and can also increase the drug excretion and accumulation of the multidrug resistance cell line.
