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 prepare mouse anti-human monoclonal antibodies against B7-H6 and to identify their biological characteristics. Methods The B7-H6 gene was cloned by RT-PCR from a human lung adenocarcinoma cell line ( A549 ) and then subcloned into the eukaryote expression vector pCMV3 to construct the recombinant vector pCMV3-B7-H6. The recombinant vector pCMV3-B7-H6 that was verified with enzyme digestion and gene sequencing was transfected into NIH/3T3 cells by electroporation. BALB/c mice were immunized with the successfully transfected cells named 2H8 through intraperitoneal injection. The monoclonal antibodies against human B7-H6 with the advantages of high affinity and specificity were pre-pared by using hybridoma technology. Western blot assay and flow cytometry analysis were used to identify the specificity of prepared monoclonal antibodies. Results The recombinant eukaryotic expression vector encoding B7-H6 was successfully constructed. Two hybridoma clones that stably secreted monoclonal anti-bodies against B7-H6 were screened out by using flow cytometry analysis and the monoclonal antibodies se-creted by them were belonged to IgG2a isotype. Specific reactions between B7-H6 and the secreted mono-clonal antibodies were confirmed by Western blot assay and flow cytometry analysis. Conclusion The mon-oclonal antibodies which recognized B7-H6 specifically were prepared successfully.

OBJECTIVE:To investigate the effects of application timing of carboporst tromethamine on postpartum hemor-rhage and hemodynamics of cesarean section women with centralplacenta previa. METHODS:Totally 138 parturient women with central placenta previa selected from our hospital during Jan.-Dec. 2015 were divided into observation group and control group ac-cording to random number table,with 69 cases in each group. Both groups received cesarean section. Control group was given Car-boporst tromethamine injection 250 μg on uterine body after the delivery of placenta. Observation group was given Carboporst tro-methamine injection 250 μg on corpora uteri immediately after umbilical cord cutting. The operation duration,intraoperative and postoperative blood loss were observed in 2 groups. The preoperative and postoperative 24 h hemodynamic index,coagulation func-tion and corpora uteri were compared between 2 groups. RESULTS:The operation duration of observation group was significantly shorter than control group;intraoperative blood loss and 24h blood loss of observation group were significantly less than control group,with statistical significance(P<0.05). There was no statistical significance in preoperative hemodynamic index and coagula-tion function index between 2 groups before surgery(P>0.05). 24 h after surgery,SBP,DBP,MAP,FIB and D-D of 2 groups were decreased significantly,while HR of them were increased significantly;the observation group was significantly better than the control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR (15.94% vs. 13.04%) between 2 groups (P>0.05). CONCLUSIONS:Carboporst tromethamine after omphalotomy via uterine body helps to shorten the operation time,reduce intraoperative blood loss,maintain hemodynamic indexes stable and improve coagulation func-tion of cesarean section women with central placenta previa ,with good safety.

OBJECTIVE:To observe the efficacy and safety of atorvastatin in the treatment of hypertension with unstable angi-na. METHODS:80 patients with hypertension with unstable angina were randomly divided into control group and treatment group. All patients were given anti-platelet aggregation and other conventional treatment;based on it,control group was orally treated with Amlodipine besylate tablet 5 mg,once a day+Metoprolol tartrate controlled-release tablet 25 mg,twice a day+Isosorbide dini-trate injection 10 ml by intravenous infusion,twice a day;treatment group was additionally treated with Atorvastatin calcium tablet 20 mg,orally,qd. 3 months was a treatment course,and it lasted 6 courses. Clinical efficacy,and systolic blood pressure,diastol-ic blood pressure,angina frequency and duration,changes of TC,TG,LDL,HDL levels before and after treatment and adverse reac-tions in 2 groups were observed. RESULTS:Total effective rate in treatment group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,systolic blood pressure and diastolic blood pressure in 2 groups were significantly lower or shorter than before,the difference was statistically significant(P<0.05),however,there was no signifi-cant difference between 2 groups(P>0.05);angina frequency and duration were significantly lower than before,and treatment group was lower than control group,TC,TG and LDL in treatment group were significantly lower than before and control group, HDL was higher than before and control group,the differences were statistically significant(P<0.05),there was no significant dif-ference between before and after treatment in control group(P>0.05). There was no significant difference in the adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Based on the conventional treatment, atorvastatin can effectively reduce the long-term angina frequency and duration of patients with hypertension with unstable angina,improve the ischemia myocardial and reduce the lipid levels with good safety.

Carefully evaluation of cardiovascular function in children with septic shock is the basis of appropriate therapy.Clinical methods of cardiovascular function evaluation include clinical manifestation,hemodynamic momtoring and laboratory test of tissue oxygenation.Evaluation of cardiovascular function should combine all results from different methods and should be dynamically monitored with the development of septic shock.

Cardioplegic (and organ preservation) solutions were initially designed to protect the myocardium (cardiac myocytes) during cardiac surgery (and heart transplantation). Due to the differences between the cardiac myocytes and vascular (endothelial and smooth muscle) cells in structure and function, the solutions may have adverse effect on coronary vascular cells. However, such effect is often complicated by many other factors such as ischemiareperfusion injury, temperature, and perfusion pressure or duration. In evaluation of the effect of a solution on the coronary endothelial function, a number of points should be taken into consideration. First, the overall effect on endothelium should be identified. Second, the effect of the solution on the individual endothelium-derived relaxing factors (nitric oxide, prostacylin, and endothelium-derived hyperpolarizing factor) must be distinguished. Third, the effect of each major component of the solution should be investigated. Fourth, the effect of a variety of new additives in the solution may be studied. In the last decades, we have focused our research on the endothelial function during open heart surgery and have for the first time found that high potassium concentration impairs the EDHF-mediated function. This review attempts to discuss the above issues based on available literature in order to provide information for further development of cardioplegic or organ preservation solutions.
