ABSTRACT
OBJECTIVE:To systematically review the procalcitonin(PCT)-guided therapy in patients with sepsis. METHODS:Retrieved from PubMed,Cochrane Library,EMBase,CJFD,Wanfang Datebase,related trails about PCT-guided therapy(test group)versus conventional treatment group(control group)in the treatment of sepsis were collected. Meta-analysis was performed by using Rev Man 5.3 software after data extraction and quality evaluation. RESULTS:Totally 5 studies were enrolled,involving 826 patients. Results of Meta-analysis showed,use time of antibiotics in test group was significantly shorter than control group, with statistical significance [MD=-2.52,95%CI(-3.07,-1.98,P<0.001];there were no significant differences in the mortality rate [OR=1.14,95%CI(0.83,1.56),P=0.42],ICU treatment days [MD=-0.22,95%CI(-1.40,0.96),P=0.72] and total hospi-talization [MD=-1.81,95%CI(-4.37,0.76),P=0.17]. CONCLUSIONS:PCT-guided therapy can effectively reduce the use of antibiotics and shorten treatment time in the treatment of patients with sepsis.It can be considered as inflammatory markers for guid-ing rational use of antibiotics in clinic.
ABSTRACT
Aim To identify the effect of policosanol on LDL-R activity.Methods In vitro cell culture experiments conventional methods were used to observe the direct effect of policosanol on mononuclear cells LDL-R.In vivo experiments self-control and negative-control group design methods were used to observe the effect of policosanol on LDL-R activity in the patients with hypercholesterolemia.LDL-R activity was analysed by fluorescence flow cytometry and labeled by the fluorescent reagent DiI.Results Policosanol 5~20 mg?L-1 obviously activated the activity of LDL-R in human mononuclear cells,policosanol levels and the activity of LDL-R in human mononuclear cells showed significantly dose-effect relationship in vitro study.These tendency could also be seen in the patients with hypercholesterolemia after policosanol treatment for four weeks in vivo study.As the increasing of policosanol dose,the activity of LDL-R in human mononuclear cells remarkably increased in the patients with hypercholesterolemia Conclusions Policosanol up-regulates the activity of the LDL-R in the mononuclear cells and reduce cholesterol level in the body.Policosanol reduce lipids through multiple ways including LDL-R.
ABSTRACT
There is no nursing information network related to nursing research, clinical test, drug, and law, although primary responsibility is on nurses about medication, and clinical laboratory test such as blood sampling. Majorities of education for nurses on medication and clinical laboratory test are not systematic, and education on medical law that can be protect nurses' right is very limited. Therefore, information exchange and communication among clinical nurses is required to expand nursing knowledge and professionalism. This study was conducted to develop nursing information contents on nursing research trend, drug, clinical test, nursing law, and medical atlas. Those can fulfil the nurses' informational needs. As a result of contents development, nursing information site was constructed that can offer all nursing related informations using direct link services. In this site, nurses can integrate informations on nursing research, nursing education, and nursing practice systematically with diversity.
