RESUMEN
Objective To evaluate the strictness and self-consistency of the charge nurses in the nurses examination using venipunctnre trocar operation as research object.Methods FACETS,the polyhedral Rasch software was used in the examination.Results The strictness and self-consistency of charge nurses were evidently different.Conclusions The variable strictness and self-consistency of the charge nurses in the examination leads to unreliability of the results.Developing a scientific and reliable evaluation system is essential to improve the ability of the teaching nurses and the student nurses as well as the hospital nursing quality.
RESUMEN
To investigate the protective effects of OLA-PENa on experimental hepatic injury in rats and compare it with OLA in the dose-response relationships. METHODS: Biochemical indexes and histopathological examination of hepatic injury in rats caused by toxicant chemicals [D-galactosamine (D-Galn) and CCl4] were determined. RESULTS: OLA-PENa obviously inhibited the rising of serum alanine transaminase (ALT) caused by D-Galn and CCl4 and dramatically decreased liver fat storage as well in a dose-dependent manner. Histopathological examination showed that OLA-PENa can evidently alleviate the condition of the degeneration of hepatic cells and that of necrosis. CONCLUSION: The protective effects of OLA-PENa on experimental liver injury in rats, all the mentioned effects, are more powerful than those of OLA with the same dosage.
