Background: Early mobilization(EM) is a regimen that was carried out by physiotherapists in a relatively early stage. It has been investigated by an increasing number of researchers. However, there has not been a meta-analysis concerning whether EM could benefit the clinical outcomes of critically ill patients requiring mechanical ventilation(MV). The present systematic review aims to evaluate the effect of EM compared with immobilization for mechanically ventilated ***: A computerized literature search was performed in six databases for related articles from inception to June 2017. We included randomized controlled trials and controlled clinical trials and used the Physiotherapy Evidence Database scale to assess the quality of included studies. Primary outcomes were measures of muscle function, duration of MV, and incidence of *** outcomes were adverse effects and length of stay(LOS) in intensive care unit(ICU) and ***: Eight trials were included; of those, only one study without standard EM reported that the intervention was invalid to improve the outcomes. The result of meta-analysis indicated that EM shortened the duration of MV; however, it had no positive effect on mortality and LOS in ***: This review suggests that EM improves the muscle function and ventilation duration. Further research highlighting standard intervention and specific groups is needed.

Objective： This meta-analysis aimed to examine the effects of parental involvement in infant care in neonatal intensive care units （NlCUs）. Methods： PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure （CNKI）, Wanfang database, and VIP database were searched till November 2017. Randomized controlled trials （RCTs） and controlled clinical trials （CCTs） examining the effect of parental involvement in the NICU were considered for inclusion. Resulls： We included 10 studies （three RCTs, seven CCTs） with a total of 1,851 participants. The meta-analysis demonstrated that there were no statistically significant differences on nosocomial infection between two groups （risk ratio [RR] = 0.90, 95% CI 0.63-1.30, P = 0.58）. Compared with no parental involvement groups, parental involvement groups showed more weight gain （mean difference [MD] = 1.47, 95% CI 0.65-2.29, P 〈 0.05）, higher breast-feeding rate （RR = 1.38, 95% CI 1.25-1.53, P 〈 0.05）, lower readmission rate （RR = 0.35, 95% CI 0.15-0.80, P 〈 0.05）, and higher satisfaction rate （RR = 1.09, 95% CI 1.02-1.16, P 〈 0.05）.Conclusions： Parentaiinvolvement in the NICU interventions could not increase the rate of nosocomial infection of neonates, but could improve their weight gain, breast-feeding and parental satisfaction and decrease their readmission. However, since the conclusion of this meta-analysis was drawn based on the limited number of high-quality RCTs, more hioh-quality studies should be conducted in the future to confirm its positive intervention effects.

Objective: The purposes of this study were to analyze the influencing factors of self-directed learning readiness(SDLR) of nursing undergraduates and explore the impacts of learning attitude and self-efficacy on nursing ***: A total of 500 nursing undergraduates were investigated in Tianjin, with the Chinese version of SDLR scale, learning attitude questionnaire of nursing college students, academic self-efficacy scale, and the general information ***: The score of SDLR was 149.99±15.73. Multiple stepwise regressions indicated that academic self-efficacy, learning attitude, attitudes to major of nursing, and level of learning difficulties were major influential factors and explained 48.1% of the variance in SDLR of nursing ***: The score of SDLR of nursing undergraduates is not promising. It is imperative to correct students' learning attitude, improve self-efficacy, and adopt appropriate teaching model to improve SDLR.
