Objective To discuss the barriers influencing the application of evidence-based nursing. Methods Nine hundred nurses from August 2013 to February 2014 were selected from five polyclinics in Shenzhen by randomly cluster sampling according to different departments and wards. We carried out the survey with the Chinese version of cognitive of impairment of nursing scientific research scale. Results The sores of 4 dimesions of scientific application of evidence-based nursing from high to low were effectiveness and system of research, resource to evidence-based nursing, quality of research and attitude and ability of nursing staff. The main barriers in applying scientific research payoffs by the nursing staff included the deficient resource and equipment provided by hospitals (68.09%), the jumbled medical development information confused the nurses in selecting related reference (66.75%), failing to put the scientific achievements into practice (66.01%),insufficient time to actualize new ideas (64.15%), and difficulty in obtaining the reference of scientific research (64.04%). Conclusion The barriers to scientrfic application of evidence-based nursing were the deficient resource and time and difficulties to find evidence. The nursing policy makers should adopt efficient measures aimed at the difficulties the nursing staff in applying their research results, thereby popularize the application of research achievements in hospitals.

OBJECTIVE:To study the effects of Heishun tablets combined with Rheum palmatum on the pharmacokinetics of hypaconitine in rats. METHODS:Rats were randomly divided into single drug group(Heishun tablets decoction)and drug combi-nation group(Heishun tablets-R. palmatum mixture decoction),with 18 rats in each group. They were given relevant drugs intragas-trically,by 10 g(medicinal materials)/kg of Heishun tablets. 0.3 ml blood samples were collected before(0 h)and 0.083,0.167, 0.333,0.5,0.75,1,1.5,2,3,4,6,8,10 h after medication with 6 rats at each time point,respectively. The blood concentra-tion of hypaconitine was determined by HPLC-MS using palmatine hydrochloride as internal standard. DAS 2.0.1 software was used to calculate pharmacokinetic parameters. RESULTS:The linear range of hypaconitine was 0.102 4-100 ng/ml (r=0.998 7),and the limit of quantification was 0.1 ng/ml. The pharmacokinetic parameters of single drug group vs. drug combination group were as follows as tmax of (0.50 ± 0.086) h vs. (0.75 ± 0.132)h;t1/2 of (9.967 ± 1.123) h vs. (3.708 ± 0.507) h;AUC0-10 h of (26.087 ± 0.672) μg·h/L vs.(6.516 ± 1.135) μg·h/L;cmax of (6.124 ± 2.312) μg/L vs. (1.592 ± 0.051) μg/L. Compared with single drug group,t1/2,AUC0-10 h and cmax of hypaconitine were decreased in drug combination group,with statistical significance (P<0.05). CONCLUSIONS:R. palmatum can inhibit the absorption of hypaconitine in rats,and speed up the elimination of it in rats.

Objective To explore job satisfaction degrees and the influencing factors among community nurses. Method General information questionnaire and the revised job satisfaction questionnaire were adopted in the investigation among 124 nurses from 28 community health service centers in Nanchong City between February to October 2016. Results The total score was (119.62 ± 15.37), at the moderate to high level. Of the eight dimensions, relationship with colleagues was scored the highest, and personal growth was the lowest. The influencing factors of the nurse's job satisfaction were found to be employment type, work positions, service duration in the community and whether they have been trained on community nursing position (all P<0.05). Conclusions The job satisfaction degree of community nurses is generally at middle level. Therefore, measures should be taken to improve the job satisfaction for the development of community nursing services.

Objective To study epidemiological characteristics of thelazjasis, in Zunyi and surrounding areas, morphology and 18S rRNA gene sequence of Thelazia callipaeda. Methods The Thelazia callipaeda was collected from several hospitals, including affiliated Hospital of Zunyi Medical College and Zunyi Aerospace Hospital, in Zunyi region since 2011 to 2015. Clinical data of infected human thelaziasis, including the patients' gender, age, residence and pets such as cats or dogs, were analyzed to find out the factors influencing the incidence. Morphology characteristics of female and male Thelazia callipaeda were observed under microscope. 18S rRNA gene of Zunyi Thelazia callipaeda was amplified by PCR, and the evolutional relationship was analyzed through the software MEGA 7.01 based on neighbour-joining (NJ) method. Homology was campared with 18S rRNA gene from GenBank in National Center of Biotechnology. Results Totally 25 cases had been reported during the study, of which 22 cases had more details. Based on the cases, we found the thelaziasis was increasing year by year. For instance, 2 cases (9.1%) were reported in 2011, 1 case (4.5%) in 2012, 3 cases in 2013 (13.6%), 10 cases (45.5%) in 2014 and 6 cases (27.3%) in 2015 . During the five years , totally 15 cases were treated between August and November, when the human thelaziasis was in typical epidemic peaks. We analyzed characteristics of the total cases reported to date. Most of the cases occurred in rural areas (20 cases). Majority of patients lived in rural region. And most cases were between 30 to 60 years old, indicating no age limit, especially, there were two cases who were at the ages of 8.5 months and 77 years old, respectively. Moreover, more women suffered from the disease than that in men, of which, the case number was 16 in women and 6 in men, and there were 7 cases who had cats or dogs at home. Under light microscope, the edge of Thelazia callipaeda had serrated cuticle with transverse striations. And male worm had a sharp peak at the tail end of Thelazia callipaeda, which cured to the ventrite and had two copulatory spicules, long one and short one, respectively. While female worm had a blunt tail, containing numerous eggs and rounded first-stage larvaes in a single line in the distal area of the uterus, near the vulva. Sequences of Thelazia callipaeda 18S rRNA gene from Zunyi and Oita Japan (AB538282.1) were showed homology of 100%, and they were clustered in a same branch of Phylogenetic tree. Conclusions Human thelaziasis cases in Zunyi region are increasing each year, and most of the cases have occurred in rural areas. 18S rRNA gene has a high homology with sequence AB538282.1 in Thelazia callipaeda. Combining clinical data, analysis of epidemiological characteristics and the characteristics of 18S rRNA should be good for specie identification and epidemiological analysis.
