Objective: To investigate the impact of levosimendan on mortality in patients with severe heart failure (HF) by Meta-analysis. Methods: We search the PubMed, EMBASE and Cochrane Central Registry of cardiovascular disease to identify all randomized impact of levosimendan vs other medications. The document retrieval was from the establishment of each database until 2014-07. The literatures were taken based on Jadad scale standard and the qualified control study was used without dose and time restrictions by Rev Man 5.2 soft ware, and a total of 37 articles with 4470 patients were finally enrolled for Meta-analysis. Results: Compared with controlling medications, levosimendan could decrease the mortality in patients with cardiac disease caused severe HF (RR: 0.85; 95% CI 0.75-0.97;P=0.02), and cardiac surgery caused severe HF (RR: 0.49; 95% CI 0.28-0.85;P=0.01). Compared with dobutamine, levosimendan could reduce the mortality in patients with severe HF (RR: 0.84; 95% CI 0.73-0.99;P=0.02) and severe ischemic HF (RR: 0.85; 95% CI 0.73-0.99;P=0.04). Conclusion: Levosimendan may reduce the mortality in patients with severe HF caused by cardiac disease, cardiac surgery and ischemic cardiac injury.

Objective To understand antimicrobial resistance and therapeutic efficacy of imipenem/cilastatin and meropenem for treatment of multidrug-resistant Pseudomonas aeruginosa (MDRPA)from patients with mechanical ventilation.Methods From January 2010 to December 2015,78 patients with mechanical ventilation and isolated MDRPA from sputum cultures were selected and divided into imipenem/cilastatin (n=44)and meropenem(n=34) treatment groups,basic condition,time of emergence of drug resistance,and therapeutic efficacy of antimicrobial agents between two groups were compared.Results The basic data of two groups were comparable,before treat-ment by imipenem/cilastatin and meropenem,resistance rates of Pseudomonas aeruginosa (P .aeruginosa )to quinolones,ceftazidime,piperacillin,and amikacin were not significantly different (all P >0.05).After patients received antimicrobial agents for 6 days,difference in antimicrobial resistance between imipenem /cilastatin and meropenem treatment groups were not significantly different (22.73% vs 8.82%,P >0.05).On the 8th,10th,and 12th day of treatment,resistance rates of imipenem treatment group were 40.91%,77.27%,and 97.73%, respectively,which were all higher than meropenem treatment group (17.65%,32.35%,44.12%,respectively,all P <0.05).After the treatment with different antimicrobial agents,the average time for the emergence of resistance in imipenem/cilastatin and meropenem treatment group were 9.0 days and 13.5 days respectively.Therapeutic efficacy between two groups was not significantly different (64.71% vs 74.19%,P =0.41).Conclusion Compared with meropenem,imipenem/cilastatin shows higher risk for the emergence of drug resistance during therapy of P . aeruginosa infection in patients with mechanical ventilation,there is no significant difference in therapeutic efficacy between two groups of patients after 7 days of treatment.

Objective: To investigate the effect of phosphocreatine (PCr) on angiotensin II (Ang II) induced proliferation and collagen synthesis of cardiac ifbroblasts in neonatal rats with its mechanism.
Methods: The cardiac ifbroblasts (CF) from neonatal rats were cultured in vitro and were divided into 4 groups.①Control group, the CF was cultured in non-serum DMEM,②Ang II group, the CF was cultured with Ang II at (1×10-6) mol/L,③PCr treated group, the CF was cultured with PCr at 10 mmol/L, and④Ang II+PCr group. The CF cell cycle percentage was detected by lfow cytometric assay, myocardial collagen content was observed by VG staining and protein expression of phosphorylated extracellular signal-regulated kinase (pERK1/2) was detected by immuneohistochemistry.
Results: ① Compared with Control group, the CF in Ang II group showed increased percentage of S phase and decreased percentage of G0/G1 and G2/M phases, increased collagen content and pERK1/2 protein expression, all P<0.01.② The CF cell cycle, collagen content and pERK1/2 protein expression were similar between Control group and PCr treated group, all P>0.05. ③ Compared with Control group, Ang II + PCr group had elevated pERK1/2 protein expression, P<0.01, while the CF cell cycle and collagen content were similar with Control group, P>0.05.④Compared with Ang II group, the CF in Ang II + PCr group had increased percentage of G0/G1 and G2/M phases, decreased percentage of S phase, decreased collagen content and pERK1/2 protein expression, all P<0.01.
Conclusion: PCr may partially inhibit Ang II induced CF proliferation and collagen synthesis which might be related to the inhibition of excessively activated ERK1/2. Therefore, PCr could improve Ang II induced myocardial ifbrosis in neonatal rats.

Objective To study the techniques for treating the intracranial tumor.Methods Through a keyhole approach with endoscope-assisted micro-neurosurgery,30 patients with intracranial tumor were treated.With microneurosurgery,larger part of tumor was resected,then under neuroendo-scope remains of tumors were found out and removed.Results Tumors were totally removed in 22 patients,subtotally removed in 5.In three patients cerebral aneurysm was clipped successfully.Two patients with pituitary adenoma had temporay diuresis and one patient non-bacteria meningitis,and after two weeks treatment all recovered.There was no-mortality in 41 patients,no cerebral hemorrhage,optic nerve injury,internal carotid injury,and other complications occurred.Conclusion Endoscope-assisted microneurosurgery through a keyhole approach can increase the total-resection rate for tumors,reduce the trauma of operation and postoperative reaction.

Chloroplast-based expression system is promising for the hyper-expression of plant-derived recombinant therapeutic proteins and vaccines. To verify the feasibility of obtaining high-level expression of the SARS subunit vaccine and to provide a suitable plant-derived vaccine production platform against the severe acute respiratory syndrome coronavirus (SARS-CoV), a 193-amino acid fragment of SARS CoV spike protein receptor-binding domain (RBD), fused with the peptide vector cholera toxin B subunit (CTB), was expressed in tobacco chloroplasts. Codon-optimized CTB-RBD sequence was integrated into the chloroplast genome and homoplasmy was obtained, as confirmed by PCR and Southern blot analysis. Western blot showed expression of the recombinant fusion protein mostly in soluble monomeric form. Quantification of the recombinant fusion protein CTB-RBD was conducted by ELISA analysis from the transplastomic leaves at different developmental stages, attachment positions and time points in a day and the different expression levels of the CTB-RBD were observed with the highest expression of 10.2% total soluble protein obtained from mature transplastomic leaves. Taken together, our results demonstrate the feasibility of highly expressing SARS subunit vaccine RBD, indicating its potential in subsequent development of a plant-derived recombinant subunit vaccine and reagents production for antibody detection in SARS serological tests.

To evaluate the effectiveness of enzymatic assisted extraction (EAE) of lipid from the oleaginous yeast Rhodosporidium toruloides in the presence of beta-1,3-glucomannanase at a larger scale, we investigated the effects of enzymatic treatment and extraction conditions on lipid extraction yields at 10-L scale by using the broth of R. toruloides Y4 as the feed and ethyl acetate as the solvent. When it was treated for 0.5 h, the lipid extraction yield reached 71.1%, indicating that the enzymatic treatment process reached similar efficiency to that obtained at 10-mL scale. The inhibitory effect of emulsification was greatly reduced by repeated extraction. After extracted for three times, yields of lipid extraction, solvent recovery and total material recovery reached 92.9%, 87.0% and 94.2% respectively. As it can use the lipid production slurry with good extraction efficiency, EAE technology is promising for industrial production of microbial lipids.
