Objective To test the reliability and validity of the Chinese version of the Comprehensive Needs Assessment Tool (CNAT) in cancer patients.Methods We translated the scale following the translation-integrationback translation-expert review procedure,conducted a pilot study among 30 cancer patients.After modifying the scale to adapt to Chinese culture,the reliability and validity of the CNAT scale was tested in a large-scale sample of 300 patients.Results The Chinese version of CNAT had 59 items with a total of seven domains.Principal component analysis resulted in an 8-factor structure explaining 70.325％ of the total variance.The Cronbach's α coefficient for the total CNAT score was 0.952,and 0.824～0.948 for every domain.Test-retest reliability was 0.807 for the overall scale,and 0.790～0.902 for every domain.The split-half for the overall scale was 0.812,and for every domain were 0.732～0.835.Conclusion The Chinese version of CNAT appears to possess adequate validity,testretest reliability and internal consistency.The newly translated Chinese version of CNAT may be used to assess the comprehensive needs of cancer patients in China.

Objective We aimed to investigate the community nurses' awareness of health policy,related behaviors and paths of learning.Methods A total of 150 community nurses were enrolled in this study by answering a self-completion questionnaire.The survey contents included general conditions of nurses,awareness,related behaviors and paths of learning of community health policy.Results 91.7％ of the respondents believed that heahh policy was important or very important,but only 10.4％ of the respondents understood health policy fully.71.5％ said that they would lecture patients health policy actively and 70.8％ would lecture their colleagues actively.51.4％ respondents would like to take part in policy-making if they were allowed.Education background,professional title and the awareness of health policy were factors of community nurses' policy related behaviors.They learned health policy by working meeting,training and documents.Conclusions It is necessary to improve their school record and adjust their professional title,to strengthen the publicity of health policy by broaden channels of publicity.By these,community nurses' awareness of health policy would be improved,their policy related behaviors would be promoted.Further,the health policy would be well delivered and implemented.

3D printing technology has been used in the diagnosis and treatment of cardiovascular diseases worldwide,i.e.,preoperative assessment of complex congenital heart disease,comprehensive assessment of novel clinical techniques,management of postoperative complications,and clinical teaching and training.Chinese hospitals introduced cardiovascular 3D printing technology from 2014.Preliminary clinical application showed that 3D printing had a positive significance,howeverit was expensive and caused inevitableloss of image information.Scholars should have an open but critical mind,actively try this technology and improve it.It can be reasonably believed as a good supplement of existing imaging tools in future.

Objective:To investigate the classification and prevalence of simple congenital coronary artery anomalies (CCAA) in Chinese in a large samples of coronary CT angiography (CCTA), and briefly summarize the CT characteristics of "malignant" anomalies.Methods:The data of patients who had undergone CCTA from July 2009 to January 2017 and were diagnosed as simple CCAA were analyzed retrospectively. CCAA were classified according to the origination, number of orifices and termination, and the prevalence of various CCAA was statistically analyzed. Anomalous origin of coronary artery included the origin of coronary artery from the opposite coronary sinus, the non-coronary sinus, the aorta or around the primary sinus, the pulmonary artery, and left circumflex artery originated from the diagonal branch. Abnormal number of orifices included single coronary artery (SCA), right coronary artery and conus branch arising separately, and left anterior descending branch and circumflex branch arising separately. Abnormal termination was coronary artery fistula (CAF). Anomalous origin of coronary artery from the opposite sinus, anomalous origin of the coronary artery from the pulmonary artery, SCA, and multiple or large CAFs were defined as"malignant"anomalies.Results:Among 165 133 patients, 2 148(1.301%) had coronary anomalies, including 1 302 (0.789%) of origin anomalies, 298 (0.181%) of abnormal number of orifices and 548 (0.332%) of abnormal termination. There were 700 cases (0.424%) with coronary artery rising from the opposite sinus, 179 of which had opening or proximal lumen stenosis due to compression, 7 of which had subendocardial myocardial ischemia or infarction on CCTA without coronary artery disease (CAD). The coronary arteries originated from posterior sinus, the aorta or around the primary sinus were found in 48 cases (0.029%), 531 cases(0.322%), respectively. Coronary artery originating from pulmonary artery was detected in 20 cases (0.012%), all of which were left main trunk originating from pulmonary artery, showed tortuous dilation of coronary arteries. Five cases showed obvious subendocardial myocardial ischemia or infarction without CAD. SCA, right coronary artery and conus branch arising separately, left anterior descending branch and circumflex artery arising separately were detected in 102 (0.062%), 53 (0.032%) and 143 (0.087%) cases respectively. Only 1 of 102 cases with SCA showed myocardial ischemia without CAD. A total of 548 cases (0.332%) were diagnosed as CAF, of which the coronary-pulmonary fistula was most common with a highest prevalence of 0.277% (458 cases). Coronary artery-atrial fistula and coronary artery-ventricular fistula were detected in 22 (0.013%) and 60 (0.036%) cases. There were 6 cases (0.004%) of coronary artery-coronary venous fistula and 2 cases (0.001%) of coronary artery-superior vena cava fistula.Conclusions:The occurrence of CCAA is not uncommon, among which anomalous origin of coronary artery is the most common, and special attention should be paid to "malignant"anomalies.
