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 explore the influence of different feeding methods on feeding tolerance and nutritional status of preterm infants.Methods Forty-eight cases of preterm infants were randomly divided into experiment group and control group,24 cases in each group.The experiment group adopt 24 hours continuous feeding by infusion pump,and the control group with syringe injection,with injection time of 3~5mins every 2 hours.The two groups were compared in terms of feeding tolerance,body weight and nutritional status.Results The feeding intolerance of experiment group was lower than that in the control group,weight and prealbumin were higher than those in the control group(P<0.05 or P<0.01).Conclusion The continuous feeding is the ideal feeding method,which can improve growth,feeding tolerance and nutritional status of preterm infants.

OBJECTIVE:To study the cardiac and skeletal toxicity of retinoic acid (RA) in Danio rerio at early life stage. METHODS:Danio rerio embryos of 24 hours post fertilization(hpf)were used as toxicity model and were exposed under medium with various concentrations of RA(0.1,1,10,25,100 μmol/L). The morphology of embryos and larvae hearts were observed 24,48 h after exposed. LC50 was calculated. Danio rerio larvae of 4 days post fertilization (dpf) were used as skeletal deformity model and were exposed with a series of RA at various concentration(0.1,1,10,25,50μmol/L). They were sacrificed 5 d later, and then Danio rerio skeleton were fixed for staining with alizarin red. The microscopic was used to observe the difference of stained skeleton area. RESULTS:RA caused significant adverse effects on hatching capabilities of Danio rerio embryos,and the ob-vious malformation features were produced during the culture process. 1-100 μmol/L RA could cause heart malformation in Danio rerio embryos and larvae,and the main heart malformation characteristics included heart linearization,pericardial edema,yolksa-cedema,hemocytes accumulation incardiac region. 100 μmol/L RA could inhibit the hatching capabilities of Danio rerio embryos, and caused lethal effects on embryos and larvae. The LC50 were 36.44,23.69 μmol/L after exposed for 24,48 h. 0.1-50 μmol/L RA induced vertebral column sclerotization of Danio rerio embryos and larvae in advance,which was positively associated with the con-centration of RA. CONCLUSIONS:RA can cause cardiac and skeletal toxicity in Danio rerio embryo and larvae,which is positive-ly associated with the concentration of RA.

Objective:To explore the effect of sub-inhibitory concentration of imipenem on the bio-activities of methicillin resistant Staphylococcus aureus(MRSA) and illuminate the inhibitory effects of carbapenem antibioty on the activity of MRSA and their mechanisms,and to provide the basis for using the carbapenem antibiotics in the treatment of MRSA infection.Methods:Five ST239 type of MRSA clinical isolates were selected and were co-cultured with 1/10 and 1/2 minimal inhibitory concentration (MIC) of imipenem for 1.5,6.0 and 12.0 h,which were divided into control group(no imipenem),1/10MIC group(1/10MIC of imipenem),and 1/2MIC group(1/2MIC of imipenem).Fluorescent quantitative real-time PCR method was used to determine the relative mRNA expression levels of virulence-related genes fibronectin A(fnbA),staphylococcal protein A(spa),α-hemolysin(Hla),leukocidin D(lek-D),leukocidin E(lek-E),and enterotoxin A in various groups;Spectrophotometry was used to detect the proliferation activity of MRSA strains in various groups in vitro.Results:After co-culture for 6.0 and 12.0 h,the proliferation activities of 5 trains of MRSA in 1/2MIC group in vitro were significantly decreased compared with control group (P<0.01).The relative mRNA expression levels of 6 virulence-related genes of 5 strains of MRSA in 1/10MIC and 1/2MIC groups were significantly decreased compared with control group(P<0.01).After co-culture for 12.0 h,the mRNA expressions of all the tested virulence-related genes were not found.Conclusion:The sub-inhibitory concentration of imipenem shows obviously inhibitory effect on the mRNA expressions of multiple virulence-related genes of ST 239 type of MRSA strains,and higher concentration of imipenem can suppress the proliferation of MRSA strains in vitro.Imipenem shows the potential value in the treatment of the severe MRSA infected patients.
