Objective To explore the clinical effect of restructuring human brain natriuretic peptide in treatment of heart failure associated with severe acute myocarditis.Methods Fifty cases of heart failure associated with severe acute myocarditis were divided into experimental group and control group according random number table method,each group 25 cases.The patients in control group were given conventional treatment,and the patients in experimental group were given restructuring human brain natriuretic peptide on the basis of conventional treatment.The clinical effects of two groups were observed.Results The level of N terminal brain natriuretic peptide,left ventricular ejection fraction,urine volume,creatinine in two groups had no significant difference before treatment (P > 0.05).After treatment,these index in experimental group were better than those in control group [(7 785 ± 432) ng/L vs.(10 022 ± 447) ng/L,(45.28 ± 2.67)% vs.(41.34 ±3.11)%,(1 833 ±49) ml/24 h vs.(1 456 ±47) ml/24 h,(109.34 ± 10.77) μmol/L vs.(125.44 ± 11.00) μ mol/L] (P < 0.05).The rate of clinical symptoms improving in experimental group was significantly higher than that in control group [71.4% (55/77) vs.26.0% (20/77)] (P <0.01).Conclusion Restructuring human brain natriuretic peptide with conventional treatment can effectively improve heart failure associated with severe clinical symptoms of acute myocarditis,improve the clinical therapeutic effect.

To study the chemical constituents of Alchornea trewioides, silica gel column chromatography, Sephadex LH-20, reverse phase ODS column chromatography, MCI and semi-preparative HPLC were used to separate the 95% EtOH extract of the root of Alchornea trewioides. The structures were elucidated on the basis of spectroscopic studies including ESI-TOF-MS, 1H NMR, 13C NMR, HSQC and HMBC. Eight phenolic acids were obtained and identified as 1-O-galloyl-6-O-vanilloyl-beta-glucose (1), gallic acid (2), ethyl gallate (3), syringic acid (4), glucosyringic acid (5), erigeside C (6), 3, 4-dimethoxyphenyl-(6'-O-alpha-L-rhamnosyl)-beta-D-glucopyranoside (7) and 3, 4, 5-trimethoxyphenyl-(6'-O-galloyl)-O-beta-D-glucopyranoside (8). Among them, compound 1 is a new compound, compounds 4-8 are isolated from the genus Alchornea for the first time, and the others are isolated from the plant for the first time.

OBJECTIVE:To explore the effects of bioactive compounds from entomogenous fungi(BCEF0083)on hip-pocampus neurons and mRNA expression of BDNF in chronic stress depression rat models.METHODS:The selected rats were randomly divided into control group,model group,moclobemide20mg/kg group,and BCEF0083100,50,25mg/kg groups.The change in hippocampus neuron numbers were observed by HE staining and mRNA expression of BDNF was detected with RT-PCR.RESULTS:BCEF0083could increase the neuron numbers and up-regulate the expression of BDNF mRNA in hippocampus.CONCLUSION:The antidepressant effect of BCEF0083in chronic stress depression rat models is probably re-lated to the increase in hippocampus neuron numbers and up-regulation of expression of BDNF mRNA in hippocampus.

The role of flavonoids of Echinps latifolius (FELT) in Wnt signaling was investigated in adjuvant arthritis (AA) rats. The therapeutic effects of FELT on AA rats were detected by rat arthritis score and MTT. The effect of FELT gavage treatment on the Wnt signaling key gene β-catenin, C-myc and cyclin D1 in synovium from AA rats was detected by Real-time qPCR, and the effects of FELT gavage treatment on the upstream negative regulation gene SFRP 1,2,4,5 in synovium from AA rats were detected by Real-time qPCR. The results showed that FELT gavage treatment significantly inhibited arthritis score and MTT values in AA rats, significantly inhibited the expression of the Wnt signaling gene β-catenin, C-myc and cyclin D1, significantly up-regulated the expression of the up- stream negative regulation gene SFRP 1,2,4. FELT has a better therapeutic effect for AA rats.

Objective To study the transduction efficiency of expressing human neprilysin by using a lentiviral vector (Lenti-NEP) in mouse embryonic neural stem cells (NSC) in vitro.Methods Primary NSC were harvested from C57BL/6J pregnant mouse at embryonic day 11.5 and transducted with LentiNEP.Immunofluorescent stainingand Western blot were performed to detect NEP protein expression in NSC.Degradation of amyloid beta 1-40 (Aβ1-40) by NEP protein transduced with Lenti-NEP in NSC was analyzed using ELISA and HPLC.Results Over 90% NSC were successfully transduced with Lenti-NEP via observation of fused protein green fluorescent protein under the microscopy.Expressions of NEP transduced with Lenti-NEP in NSC and of the markers of NSC (nestin) and neuron (MAP2).The enzyme activity of 2.5 μg (21.00 ± 2.51) and 1.0 μg (15.00 ± 0.54) NEP on degrading Aβ1-40 was shown to improve significantly compared to 0.5 μg NEP(8.00 ±0.81,t =40.4 and 12.7,respectively,both P <0.01).The activity of NEP was inhibited in the presence of 50 μmol/L phosphoramidon (0.5 pg:0.08 ±0.01 ;1.0 μg:0.04 ±0.01 ;2.5 μg:0.05 ±0.01,t =17.2,51.3 and 14.1,respectively,all P <0.01).The hydrolytic cleavage on degrading Aβ1-40 by NEP was 11.4%,28.4% and 93.7% with incubation for 1 h,4 h and 12 h,respectively.Conclusions Lentiviral vector successfully delivers NEP gene to NSC in vitro.Targeting on NEP and NSC may provide potential therapeutic tool for Alzheimer' s disease.

Aim To study the antidepressant effects of bioactive compounds from entomogenous fungi(BCEF) in mouse models of depression. Methods The antidepressant effects of Bioactive compounds from entomogenous fungi was examined on the chronic unpredictable stress test, yohimbine induced lethality test, and 5-HTP induced head-twitches test. Results BCEF(50 mg?kg~-1 , ig, qd?21 d)could significantly increase the crossing and rearing score in open-field test. After administration yohimbine 1 h, BCEF 100 mg?kg~-1 group mice mortality rate rising rapidly; BCEF(50,100 mg?kg~-1 ) could distinctly increase the head-twitch number in the 5-HTP induced head-twitches test. Conclusion BCEF has antidepressant effects in depression mouse models. The mechanisms of its antidepressant effects may be related with the reinforcement of central monoamine neurotransmitter especially to 5-HT and NE nerves system.
