Objective We sought to develop Nurse Job Performance Scale and test its validity and reliability.Methods Initial version of Nurse Job Performance Scale was formulated by using literature review and qualitative interview.By cross-sectional investigating of 562 nurses in coastal cities by convenience sampling as well as screening and selecting items through item analysis,the validity and reliability was tested under the statistics.Results Three factors containing 14 items were extracted by using exploratory factor analysis:work coordination,working enthusiasm and work involvement.The average value of factor loading was between 0.643～0.839,the 3 factors explained 73.9％ of the total variance.The total Cronbach's α was 0.937 and the Cronbach's α coefficients of every dimension were between 0.767～0.930.Conclusions Nurse Job Performance Scale has good validity and variability.

PET/CT imaging can reflect the physiological metabolic process in living body which is the model experiment incapable to simulate. Animal experiment may be considered for systematic validation of PET/CT products. The obtained research data can be used to evaluate the feasibility, effectiveness and safety of PET/CT products, and be submitted as supporting documents for research data or clinical evaluation data when doing product registration or alteration registration. In this study, the functions and advantages of animal experiments were expounded, and relevant research cases were given as well as the issues that should be paid attention to. It can be a reference for the validation and review of PET/CT products.

Objective To investigate electroencephalographic (EEG) characteristics of anti-N-methyl-D-aspartate (anti-NMDA) receptor encephalitis during different courses of the disease. Methods This study enrolled 30 cases of anti-NMDA receptor encephalitis patients. A total of 58 EEG monitoring reports and their clinical data were retrospectively analyzed based on different disease courses and severity of disease. According to the clinical stages, EEG data was divided into 4 phases: the initial stage (4), the peak stage (23), the improvement stage (16) and the recovery stage(15). Based on severity of disease during the peak stage, patients were divided into mild group(10 cases) and severe group (13 cases). Results Occipital background activity of the EEG was presented in all patients (100%) in the initial stage and in the recovery stage, in 39.1%(9/23)in the peak stage and in 13/16 (81.2%)in the improvement stage. Generalized rhythmic delta activity (GRDA) pattern could only be detected in the peak stage and the improvement stage. In the peak stage, the main presentation of abnormal EEG was diffuse slow-wave (9 cases, 90%) in mild group. GRDA and extreme delta brush(EDB) were more common in severe group than in mild group(P<0.05). Three focal epilepsy including one status epilepticus were detected in three patients in the peak stage. Focal epileptiform discharges in EEG existed in the whole course. Conclusion Occipital background activity and GRDA pattern are evolved and gradually recovered during the course of the disease. The EEG patterns of GRDA and EDB are common in severe anti- NMDA receptor encephalitis patients in the peak stage. Focal epileptiform discharges in EEG can be detected during the whole course.
