Nurses are the highest numbered
healthcare professionals who work in a knowledgedriven
environment, where accurate and updated
information is needed when delivering care to clients.
Information literacy has therefore become one of the
criteria in determining nurses’ readiness for evidencebased
practice in recent years. In the actual day-to-day
care practice, are nurses ready for this?
Objective: To determine the information literacy

Objective To investigate whether TG2 plays an important role in the osteoblast differentiation and mineralization.Methods TG2 mRNA of SaOS-2 cells was knocked down using a lentivirus stably expressing short-hairpin ( sh) RNA targeting TG2.Then the cells were cultured in osteo-inductive medium for 14 d to measure mineralization and for 7 d to measure the levels of osteoblastic differentiation markers including ALP activity and mRNA of collagen I, osteocalcin ( OCN) and BMP-2.The wild-type SaOS-2 cells and scrambled shRNA-transducted SaOS-2 cells served as the controls. Results The controls displayed an increasing trend of the level of ALP activity and mRNA of collagen I, osteocalcin and BMP-2,and notable mineralization at 14 d.When TG2 was knocked down, ALP activity, mRNA of collagen I, osteocalcin and BMP-2 at 7d,and mineralization at 14 d were all significantly lower in comparison with the corresponding values in the controls.Conclusion TG2 is involved in the differentiation and mineralization of osteoblasts in vitro.

Objective To investigate the effect of raloxifene on ERα, ERβ and MT-1a expression in renal tubular epithelial cells contaminated with cadmium chloride,for exploring the protective effect and action mechanism of raloxifene in renal injury induced by cadmium. Methods Renal tubule cells were isolated from kidneys of new born SD rats and purified by Percoll. The cells of the second generation were selected for experiment. The cells were divided into 3 groups:blank control group,cadmium chloride group and raloxifene group. After 4 h,cell viability was detected by MTT,and after 24 h,mRNA and protein expression levels of ERα, ERβ and MT-1a in renal tissues were determined by RT-PCR and immunohistochemistry technology,respectively. Results Compared with the blank control group,morphology of plenty cells were changed in cadmium chloride group,a number of cells were dead,and the survival rate was only 55.3%;at the same time,mRNA and protein expression levels of ERβ and MT-1a significantly increased (P<0.05). Compared with cadmium chloride group,only a small part of cells underwent morphological changes,and the survival rate was 88.6% in raloxifene group,and the mRNA and protein expression levels of ERβand MT-1a were significantly decreased ( P<0.05) . The expression of ERαshowed no significant difference among the three groups ( P>0.05) . Conclusion Raloxifene can bond with ERβcompetively,down-regulate MT-1a and decrease Cd-MT synthesis,so as to reduce cadmium-induced damage of renal tubular epithelial cells.

OBJECTIVETo evaluate the feasibility and stability of chemically conjugating IgM on collagen films.
METHODSIgM was labeled with 125I using the chloramine-T method. Six collagen films were randomly divided into two groups. In chemical coupling group 125I-labeled IgM was chemically coupled with the films through N-succinmiclyl-3- (2-pyridyl-dithio) propionate reaction. In control group 125I-labeled IgM was absorbed onto collagen films. The amount of IgM on the collagen films and the amount of IgM remained on the films after extensive rinsing with phosphate buffered saline were monitored by counting the radioactivity of 125I.
RESULTSThe amount of antibodies loaded onto collagen films in the chemical coupling group was 15 times higher than that on the control films, showing significant statistical difference (P < 0.01). And the stability of conjugation antibodies on collagen films was significantly better than the control films.
CONCLUSIONChemical coupling is an effective approach to immobilize antibodies on collagen for further plasmid DNA tethering.
