Objective To investigate the self-management behaviors in patients with liver cirrhosis and analyze its influencing factors. Methods Totally 103 liver cirrhosis patients were recruited by convenience sampling method. They were investigated by using Self- management Questionnaire for Chinese patients with liver cirrhosis. Results The total score of self-management behaviors was 63.69 ± 13.60. All subscales scoring from high to low in turn were medication, diet management, condition monitoring and daily management. Conclusions The self-management level in patients with liver cirrhosis of decompensation period need to be improved, nursing staff should pay attention to effect evaluation during the hospital health education, to ensure that patients can master disease self-management knowledge, to improve the self-management behavior of patients with liver cirrhosis.

Objective To systematically assess the efficacy and safety of non-indwelling urinary catheter during perioperative period of cesarean section.Methods The databases including Medline(PubMed),EMbase,Cochrane Library,CNKI and WanFang Data were retrieved by computer.The randomized controlled trials (RCTs) on the efficacy and safety of non-indwelling urinary catheter during perioperative period of cesarean section were comprehensively collected.Two reviewers independently screened literatures,extracted the data and assessed the quality.The Meta-analysis was conducted by using RevMan 5.3 software.Results A total of 5 RCTs involving 1 090 patients were included.The meta-analysis results showed that compared with the indwelling urinary catheter group,although the non-indwelling urinary catheter group increased the incidence rate of urinary retention[RR=11.67,95%CI(2.22,61.24),P<0.01],but significantly decreased the incidence rate of urinary tract infection(UTI) [RR=0.10,95%CI(0.04,0.26),P< 0.01] and incidence rate of initial urination discomfort [RR=0.17,95%CI (0.04,0.74),P=0.02],significantly shortened the initial time of off-bed activities [SMD=-3.68 ,95%CI(-5.25,-2.12),P<0.01]and hospitalization time [SMD=-1.03,95%CI(-1.67,-0.38),P<0.01].There were no significant differences in the operation time[SMD=-0.13,95%CI(-0.32,0.07),P=0.20] and incidence rate of postpartum hemorrhage (PPH)[RR=1.50,95%CI (0.43,5.26),P=0.53],The incidence rates of bladder injury in the two groups were similar.Conclusion According to the evidence of current clinical researches,selecting non-indwelling urinary catheter in elective cesarean section is effective and safe,prompting that indwelling urinary catheter during the perioperative period of cesarean section is selective rather than routine indwelling.
