Objective By reviewing the relevant literature, we explored the current status and problems of the evaluation of the training effectiveness, and put forward the corresponding countermeasures, in order to provide a theoretical basis for the effect evaluation of nurse training in China. Methods By searching Citation online search and integration system (CITE), the Chinese biomedical literature service system (CBM), we included the literatures on the effect evaluation of the nurses training in the core journals from January 2006 to November 2015. Retrieval literatures were imported the bibliographic management software Note express by database. The corresponding field were analyzed in the literature′s age distribution, evaluation object, evaluation model, evaluation method, evaluation index and evaluation tool, et al. Results There were 343 literatures had retrieved, the total number of literatures presented a increasing tendency. The evaluation methods, evaluation tools and evaluation indicators presented a tendency of diversity, and the evaluation model was relatively single. Only 16 (4.7%) literatures tried to construct the training effect evaluation system of nurses, which was not based on some theory or hypothesis, which had not been effectively put into practice. Conclusion The effect evaluation system of nurse training needed to be done in depth, such as reconstruction of the new training evaluation model, the establishment of training evaluation system of different professional, different levels, different positions, to research evaluation methods, evaluation criteria and clinical practice testing, to design, training evaluation management software etc.

Objective To quantitatively evaluate the left ventricular systolic synchrony in patients with chronic renal failure (CRF) by real-time three-dimensional echocardiography (RT-3DE). Methods Thirty patients with CRF and twenty-five normal subjects were enrolled in this study.The M-mode ejection fraction (M-EF), left ventricular end diastolic internal diameter (LVIDd), interventricular septum diameter (IVSd), left ventricular posterior wall diameter (LVPWd) were obtained on two-dimension. The global and regional volume-time curves were obtained on three -dimensional. The end diastolic volume (LVEDV),end systolic volume (LVESV) and ejection fraction (LVEF) of left ventricule, the time to minimal systolic volume (Tmsv) of 16,12,6-segmental standard deviation (Tmsv16, 12, 6-SD), maximal difference (Tmsv16, 12, 6-Dif) were derived from Qlab software . The above parameters as a percentage of the cardiac cycle with different heart rates between patients were also calculated from the Qlab software, which were Tmsv16, 12, 6-SD% and Tmsv16, 12, 6-Dif %, rspectively. Results The indices of HR, LVIDd, IVSd, LVPWd and LVESV were significantly higher while LVEF was significantly lower in the CRF group than those of the control group (P<0.05 or P<0.01); The indices of systolic asynchrony of Tmsv16,12-SD%, Tmsv16,12-Dif, Tmsv16 ,12 ,6-SD/R-R%,Tmsv16,12,6-Dif/R-R% were significantly larger in the CRF group than those of the control group(P<0.05 or P<0.01). Conclusions RT-3DE provides a simple, intuitional and noninvasive approach to assess the systolic synchrony of all the LV segments simultaneously and LVEF in patients with chronic renal failure.

Emodin is an effective active ingredient extracted from Chinese herbal medicine, which has the function of antimicrobial, anti-inflammatory, antioxidant and scavenging oxygen free radicals, inhibiting platelet aggregation, improving microcirculation, protecting various organs and tissues as well as a wide range of anti-tumor effect. Primary biliary gallbladder is a common malignant tumor resection rate and lack of effective adjuvant treatment. It has been confirmed that emodin has broad spectrum antitumor effect, whereas, whether it has curative effect in the treatment of gallbladder carcinoma there is no reliable clinical trials confirmed that its resistance to gallbladder carcinoma function needs further experimental research. In this review, we report the research progress of emodin anti-gallbladder carcinoma.
