Radial versus femoral artery access for percutaneous coronary angiography and intervention: a systematic review and meta-analysis of randomized controlled trials in Chinese population.

To compare the feasibility, efficiency and safety of coronary angiography (CAG) and interventional procedures between the radial and femoral catheterization approaches in Chinese population using systematic review and meta-analysis, we conducted a search of the studies comparing radial and femoral catheterization approaches in patients underwent either CAG or percutaneous coronary intervention (PCI) in Chinese population. Fixed-effect relative risk (RR) for the primary end points and the second end points were compared between the two approaches. A total of 27 studies (n=8,749 patients) were finally included in the analysis.

[Study on the effect of H2O2 against Acanthamoeba in vitro].

Objective: To detect the effect of H2O2 on Acanthamoeba spp..

Methods: By Wright's stain, quantitative culture, MTT assay and lactate dehydrogenase(LDH) assessment, the influence of H2O2 on the morphological feature, proliferation speed and the survival rate of Acanthamoeba was tested.
