Objective To investigate the atypical CT ,MRI findings of pancreatic neuroendocrine tumors (PanNETs) ,in order to improve diagnosis .Methods The clinical ,imaging and pathological data of 6 patients with PanNETs confirmed by pathology were analyzed retrospectively .Results In all 6 cases ,2 lesions were located in the pancreatic head ,3 lesions in the pancreatic body ,and 1 lesion in the pancreatic tail .There were 2 functional PanNETs with an average size of 2 .1 cm × 2 .6 cm ,which showed homogeneous density or signal .There were 4 nonfunctional PanNETs with an average size of 2 .7 cm × 4 .3 cm ,one of which had calcification ,and two of which had obviously cystic change ,including intracapsular bleeding in one case .Contrast‐enhanced examinations showed that all 6 lesions had mild or moderate enhancement .Three lesions were manifested as relatively intense enhancement in the arterial and portal venous phase ,but decreased enhancement in the delayed phase ,including annular envelope enhancement in one case .Two le‐sions were manifested as progressive enhancement .The last case was manifested as inwardly filled enhancement .Three lesions had unclear boundaries ,while one lesion had splenic vein invasion .Two cases accompanied with mild expansion of the common bile duct or pancreatic duct .Conclusion PanNETs can be ma+nifested as atypical findings such as obviously cystic changes ,and(or) mild to moderate enhancement .It is suggested that the atypical imaging findings of PanNETs should be recognized well to improve the diag‐nostic accuracy .

Objective To learn the publications and influencing factors of scientific papers from nursing staff in China.Methods 750 authors were chosen in a stratified random sampling for survey,and the questionnaires included a survey form on nursing research papers publications and one research ability self-rating scalce Results The nursing staff surveyed published 1-70 papers per person,averaging 8.83papers per person; on average 0.45 papers were published per person per year.Main factors for research outputs range from high to low as follows:age,academic titles,research ability,education background and research training,with the Beta values of 0.255,0.234,0.142,0.093,and 0.087 respectively.Conclusion Nursing administrators need to develop respective objectives for nursing staff of different age,academic titles,education background and research ability,and set up an effective incentive mechanism to ignite the enthusiasm of scientific research.

Objective To identify main factors affecting the research capacity of nursing staff for efficient elevation of such a capacity. Methods 1000 persons were chosen in a random coded sampling for completion of questionnaires, including a general information questionnaire, research capacity self-assessment questionnaire, nursing professional value scale and work satisfaction scale for nursing staff. Results Main factors for the research capacity range from high to low the following: education, work satisfaction, training involvement, cognitive value, and nature of their employer. Beta values of such factors are found to be 0. 323, 0. 234, 0. 182,0. 064, and 0. 062 respectively. Conclusion Administrators of nursing staff need to focus on the development of the work values and satisfaction of nursing staff, on top of developing their research methodology and knowledge. This approach may encourage them to proactively involve in research activities.

Objective To explore the issues related to the standardized training of resident doctors at the primary hospital and provide basis for the standardization of doctors' training. Methods Questionnaires were used to investigate the resident titles, ages, and education background in the Huanxian People's Hospital. The self-assessment of the competency of resident doctors and professional contents necessary for their improvement were analyzed to identify the medical topics should be recommended to improve their clinical knowledge and techniques. Results Forty-six of 52 registered residents in the Huanxian People's Hospital participated in the survey with a participation rate of 88.5%. In this hospital, mainly the title of physicians was resident, accounting for 43.3% (52/120), the ages were chiefly in the range of 31 - 35 years, and their education levels were college degree 42.3% (22/52) and bachelor degree 48.1% (25/52). 76.1% (35/46) of the residents found they had difficulties in working and not competent enough on the present post, and 71.7% (33/46) of residents considered that they were in urgent need to strengthen their trainings of clinical thinking and clinical skills. Conclusions Strengthening the residents' self academic qualifications, improving the hospital teaching system, enhancing the teaching management, and focusing on clinical thinking and clinical skills training are the main issues in the current standardized training in primary hospitals. By accelerating the standardized training of residents, they may have the chance to transform to be the middle-level physicians and improve the unreasonable structure of doctor title distribution that will play the key role in the development of primary hospitals.

Objective To understand effects of the interventional operation on thyroid,peripheral blood indexes and chromosomal aberrations (CA) of peripheral lymphocyte of children with congenital heart disease (CHD).Methods Follow-up studies were conducted in 70 child patients undergoing cardiac catheterization and 23 with open heart surgery as control from 2010 to 2013.Postoperative follow-up examinations included thyroid ultrasound,blood routine indexes and analyses of CAs.Results Difference in thyroid ultrasound abnormality rate was not statistically significant between children with cardiac catheterization and control group (40.0％ vs.43.5％,P ＞ 0.05).There was no significant difference in white blood cell (WBC) count between interventional group and control group (P ＞ 0.05).The effects of disease type and operation time on thyroid ultrasound and WBC count were not observed (P ＞ 0.05).The frequency of chromosome aberrations,including acentric fragment,dicentrics and translocation in interventional group [(0.76 ± 0.07) ％],was higher than in control group [(0.25 ± 0.07) ％,(Z =-3.631,P ＜ 0.05],and the rates of acentric fragment and translocation were also higher in interventional group (Z =-2.531,-2.397,P ＜ 0.05).Conclusions Effect of intervention therapy on thyroid structure and WBC count in children with CHD was not observed,but the genotoxic effects remain in children with cardiac catheterization.
