Full text of literatures on randomized clinical trials (RCTs) of intracoronary infusion of autologous bone marrow-derived stem cells (BMSCs) transplantation in patients with acute myocardial infarction (AMI) published at home and abroad were systematically retrieved and reviewed from PubMed database and the China Full Text Journal database to assess its efficacy and safety. Fifteen RCTs were included in a recta-analysis with RevMan version 5. 0 software after strict and standard screening. Results showed that global left ventricular ejection fraction (LVEF) in the patients with BMSCs transplantation improved significantly ( P < 0. 01 ), but no obvious change in their left ventricular end-diastolic volume (LVESV) was observed. Occurrence of end-stage cardiovascular events also decreases significantly ( OR =0. 51, 95% CI =0. 36-0. 72) in patients with AMI.

Quantitative specific detection of Staphylococcus aureus is based on recombinant lysostaphin and ATP bioluminescence. To produce recombinant lysostaphin, the lysostaphin gene was chemically synthesized and inserted it into prokaryotic expression vector pQE30, and the resulting expression plasmid pQE30-Lys was transformed into E. coli M15 for expressing lysostaphin with IPTG induction. The recombinant protein was purified by Ni(2+)-NTA affinity chromatography. Staphylococcus aureus was detected by the recombinant lysostaphin with ATP bioluminescence, and plate count method. The results of the two methods were compared. The recombinant lysostaphin was successfully expressed, and a method of quantitative specific detection of S. aureus has been established, which showed a significant linear correlation with the colony counting. The detection method developed has good perspective to quantify S. aureus.

Objective: To explore the regulative role of extracellular regulated protein kinase-5 (ERK5)/Bcl-2 interacting mediator of cell death (Bim) pathway in hypothermal stimulation induced neonatal rat’s cardiomyocytes (CMs) damage and apoptosis.
Methods: CMs were cultured for hypothermal stimulation and the speciifc siRNA was used to down-regulate the ERK5 or Bim in CMs. The cell apoptosis was detected by lfow cytometry, protein expression was examined by Western blot analysis, the intracellular Ca2+, reactive oxygen species (ROS) and mitochondrial membrane potential (ΔΨm) were evaluated by lfuorescent labeling and lfow cytometry.
Results: In hypothermal stimulated CMs, ERK5 siRNA could promote Bim protein expression, but Bim siRNA could not inlfuence ERK5, while attenuated p-ERK5 expression. ERK5 siRNA induced higher apoptosis rate, while Bim siRNA could decrease such effect. ERK5 siRNA increased the intracellular Ca2+overloading, ROS activation andΔΨm damage, while Bim siRNA played the role to against those effects in hypothermal stimulated CMs.
Conclusion: Our study revealed that ERK5/Bim pathway played the important regulative roll in hypothermal stimulation induced neonatal rat’s CMs damage and apoptosis.
