Objective To explore the effects of curriculum provision of nursing risk management in standardized training of new nurses. Methods Totally 140 new recruits nurses from the year 2011 to 2014 were divided into control group and experimental group with 70 cases each. The control group received standardized training. In addition, the experimental group added the curriculum of nursing risk management from different levels in the basis of standardized training. Data were statistically analyzed according to the examination results, incidence of nursing safety events ( adverse events) and post admittance rate of new nurses, in order to evaluate the effects. Results The examination results after standardized training and post admittance rate of the experimental group were higher than those of the control group:(83.61 ±6.90) points vs. (80.13±10.58) points,95.7%(67/70) vs. 82.9% (58/70), and there were significant differences, t=-2.309,χ2=6.05, P<0.05. And the incidence of nursing safety events ( adverse events) of the experimental group was lower than that of the control group in standardized training: 1.4%(1/70) vs.11.4%(8/70 ),and there was significant difference, χ2=4.275, P<0.05. Conclusions The curriculum provision of nursing risk management can enforce the safety consciousness of new nurses , culture them self-conscious and standardized nursing behaviors, reduce the incidence of nursing safety events ( adverse events) and improve the work ability of new nurses.

Objective To apply the feedback closed-loop management systemin the telephone follow-up service for discharged patients to increase patient satisfaction and improve the quality of nursing. Methods From January 2015,telephone return visit to discharged patients were analyzed, a summary of dissatisfaction events, analyze the causes every month. Then,the improvement measures for nursing quality were put forward and the effects were evaluated to form a closed-loop management system. Results After the application of feedback closed-loop management system,there was a significant difference in patients' satisfaction with nursing service between the first half (with the incidence of 91.77%,3657/3985) and the second half (with the incidence of 95.76%,3610/3770) of 2015 (χ2=52.22, P < 0.01). Of the 9 items of dissatisfaction recorded in the questionnaire, significant difference was observed in 8 items, as service attitude, hospitalizing education, personal care, question answering, nurse's operation, health education, respect, clean environment and the discharge instructions. The incidence of each item was 2.11%(84/3985), 0.23%(9/3985), 0.35%(14/3985), 0.33%(13/3985), 0.30%(12/3985), 2.99%(119/3985), 0.33%(13/3985), 0.58%(23/3985), 2.58%(103/3985) in the first half of 2015 respectively, compared to 1.09%(41/3770), 0.05%(2/3770), 0.05%(2/3770), 0.08%(3/3770), 0.21%(8/3770), 0.64%(24/3770), 0.85%(32/3770), 0.21%(8/3770), 1.25%(47/3770) in the second half of 2015 respectively (χ2=4.084-59.088,P<0.01 or 0.05). However, no significant difference was observed in the nurse operational between the first half (0.30%) and the second half (0.21%) in 2015 (χ2=0.596, P>0.05). Conclusions Feedback closed-loop management systemic a scientific management theory. It can increase patient satisfaction with nursing service,improve the quality of nursing,and make quality management more scientific and effective .

Tooth enamel is prone to be attacked by injurious factors, leading to a de/remineralization imbalance. To repair demineralized enamel and prevent pulp inflammation caused by biofilm accumulation, measures are needed to promote remineralization and inhibit bacterial adhesion on the tooth surface. An innovative material, poly (aspartic acid)-polyethylene glycol (PASP-PEG), was designed and synthesized to construct a mineralizing and anti-adhesive surface that could be applied to repair demineralized enamel. A cytotoxicity assay revealed the low cytotoxicity of synthesized PASP-PEG. Adsorption results demonstrated that PASP-PEG possesses a high binding affinity to the hydroxyapatite (HA)/tooth surface. In vitro experiments and scanning electron microscopy (SEM) demonstrated a strong capacity of PASP-PEG to induce in situ remineralization and direct the oriented growth of apatite nanocrystals. Energy dispersive X-ray spectroscopy (EDS), X-ray diffraction analysis (XRD) and Vickers hardness tests demonstrated that minerals induced by PASP-PEG were consistent with healthy enamel in Ca/P ratio, crystal form and surface micro-hardness. Contact angle tests and bacterial adhesion experiments demonstrated that PASP-PEG yielded a strong anti-adhesive effect. In summary, PASP-PEG could achieve dual effects for enamel repair and anti-adhesion of bacteria, thereby widening its application in enamel repair.
