To construct “developmental assessment” in the course of emergency nursing and inten-sive care nursing by applying the combination of formative assessment and summative evaluation, the com-bination of qualitative assessment and quantitative assessment and the incorporation of self-assessment and other evaluation. Specifically, this project contains investigation activity (accounting for 10%), operating activity (10%), checking on work attendance and homework evaluation (15%), reflection activity (15%), comprehensive design experiment evaluation (20%) and theoretical evaluation (30%). Process evaluation and self-evaluation are highlighted, especially feedback and improvement after evaluation. Through multi stage and multi form evaluation, the goal of emergency and critical care professional education has been achieved, which has promoted the development of student nurses' quality and overall development.

Objective To compare three dimensional arterial spin labeling(3D-ASL) and dynamic susceptibility contrast-perfusion weighted imaging(DSC-PWI) in evaluating the cerebral hemodynamic of Moyamoya disease. Methods Approved by the institutional review board, 26 cases of Moyamoya patients who were diagnosed by DSA were enrolled. Diffusion weighted image, 3D-TOF-MRA, 3D-ASL, DSC-WPI, and T1WI were performed in 3.0 T MR scanner. ROI were positioned in the abnormal perfusion areas and the control area according to the arterial dominant territory to obtain quantitative parameters of perfusion. Perfusion parameters including cerebral blood flow(CBF) of ASL, cerebral blood flow(CBF), cerebral blood volume(CBV), mean transit time(MTT), and time to peak(TTP)of DSC-PWI , and relative parameters (ASL-rCBF, DSC-rCBF, DSC-rCBV, DSC-rMTT, DSC-rTTP) that the ratio of abnormal perfusion area and the control area were calculated. Meanwhile, the areas of the lower perfusion region of ASL and TTP images in the same slice were measured. Difference of the above-mentioned parameters and areas was processed by paired Student′ t test. Furthermore, correlation of relative values of perfusion parameters(ASL-rCBF, DSC-rCBF, DSC-rCBV, DSC-rMTT, and DSC-rTTP) was processed by Pearson correlation test. Results There were significant statistics differences between values of ASL-CBF, DSC-MTT, and DSC-TTP in abnormal perfusion [(28.18 ± 10.19)ml · 100 g-1 · min-1,(7.98 ± 2.22)s,(29.93 ± 3.95)s] and the control areas [(49.50 ± 11.37)ml · 100 g-1 · min-1,(6.07 ± 1.11)s,(27.34 ± 2.58)s] (t=-12.818, 4.193, 6.163, all P<0.01). There was no significant statistics difference in the lower perfusion area between ASL-CBF [(5 729.63 ± 4 563.79) mm2]and DSC-TTP[(5 875.33 ± 4 723.08)mm2](t=-1.774,P>0.05). Furthermore, the Pearson correlation test showed significant linear dependence between ASL-rCBF(0.56±0.14)and DSC-rMTT(1.34± 0.42), and DSC-rTTP(1.09 ± 0.69)(r=-0.630,-0.748, P<0.01). Conclusions There is a correlation between 3D-ASL and DSC-PWI in assessing the magnitude and areas of the reduction of blood perfusion of Moyamoya patients. Moreover, the ASL technique possesses advantages of non-invasion use of the gadolinium contrast.

Objective:To describe demographic,clinical and physiological characteristics,treatment between first-episode major depressive disorder(MDD)and relapse MDD,and to explore characteristics of relapse MDD.Methods:Totally 858 patients who met the diagnostic criteria for depression of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5),were included by using the Mini International Neuropsychiatric Interview(MINI),Clinician-Rated Dimensions of Psychosis Symptom Severity,and Hamilton Depression Scale etc.Among them,529(58.6％)were first-episode depression and 329(36.0％)were relapsed.The differences of demographic characteristics,clinical and physiological characteristics,treatment were compared byx2test and Kruskal-Wallis rank sum test.Multivariate logistic regression was used to explore the characteristics of MDD recur-rence.Results:Compared to first-episode MDD,relapse MDD had more comorbidity(OR=2.11,95％CI:1.00-4.44),more days out of role(OR=1.26,95％CI:1.01-1.56),more history of using psychiatric drug more than one month(OR=1.41,95％CI:1.02-1.97)and electroconvulsive therapy(OR=3.23,95％CI:1.42-7.36),and higher waist-hip ratio(OR=33.88,95％CI:2.88-399.32).Conclusion:Relapse MDD has positive as-sociation with comorbidity of mental disorders,out of role,and higher waist-hip ratio.
