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 comprehend the sense of competence and depression status for neonatal father and explore the relationship between them in order to provide evidence for the improvement of psychological and physical health. Methods A total of 180 3 days neonatal father had been chosen by convenience sampling method in 5 three-level hospitals in Xi′an. We utilized Edinburgh Postnatal Depression Scale and the Chinese version of the Parenting Sense of Competence Scale ( PSCS) to survey neonatal father by questionnaire and analyzed neonatal father′s sense of competence and depression by Spearman correlation analysis. Results The average score of neonatal father′s PSCS acquired (69. 74 ± 8. 40) while there were 35 (21. 08%) father felt depression. Parenting sense of competence had negative correlation with postpartum depression (r= -0. 510,-0. 507,-0. 326,respectively;P<0. 01). Conclusions The depression of neonatal father is one issue neglected which could impact on parenting sense of competence.

Objective To investigate the application effect of the collaborative noviciate teaching mode in the nursing undergraduates. Methods With the convenience sample method, 112 noviciate nursing students in the school of nursing of He'nan University of Science and Technology from September 2014 to September 2015 were included and divided into the observation group (56 students) and the control group (56 students) using the random number table. The students in the control group were taught with the conventional noviciate teaching mode. The students in the observation group were taught with the collaborative noviciate teaching mode. The noviciate nursing students in the two groups were evaluated with the comprehensive assessment questionnaire and the satisfaction questionnaire. The Professional Self-Concept of Nurses Instrument was used for the comparison of the internship nursing students in the two groups. Results The nursing skill operation score and the score of case studies of the noviciate nursing students in the observation group were significantly higher compared to the control group (t=3.15,6.07; P<0.01).The satisfaction of the noviciate mode and the noviciate effect of the noviciate nursing students in the observation group were both significantly higher compared to the control group (t=6.67,3.21; P< 0.01). The communication dimension, the skill dimension, the leadership dimension of the internship nursing students in the observation group were significantly higher compared to the control group(t=2.41,2.58,3.75;P<0.05). Conclusions The collaborative teaching noviciate mode not only promotes the noviciate effect of the noviciate nursing students effectively, and also promotes the improvement of the self-concept of the internship nursing students, which is profoundly valuable.

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.

Background::The study aimed to describe the aortic valve morphology in Chinese patients underwent transcatheter aortic valve replacement (TAVR) for symptomatic severe aortic stenosis (AS), and the impact of sizing strategies and related procedural outcomes.Methods::Patients with severe AS who underwent TAVR were consecutively enrolled from 2012 to 2019. The anatomy and morphology of the aortic root were assessed. "Downsize" strategy was preformed when patients had complex morphology. The clinical outcomes of patients who performed downsize strategy were compared with those received annular sizing strategy. The primary outcome was device success rate, and secondary outcomes included Valve Academic Research Consortium-3 clinical outcomes variables based on 1-year follow-up.Results::A total of 293 patients were enrolled. Among them, 95 patients (32.4%) had bicuspid aortic valve. The calcium volume (Hounsfield Unit-850) of aortic root was 449.90 (243.15-782.15) mm 3. Calcium is distributed mostly on the leaflet level. Downsize strategy was performed in 204 patients (69.6%). Compared with the patients who performed annular sizing strategy, those received downsize strategy achieved a similar device success rate (82.0% [73] vs. 83.3% [170], P= 0.79). Aortic valve gradients (downsize strategy group vs. annular sizing group, 11.28 mmHg vs. 11.88 mmHg, P = 0.64) and percentages of patients with moderate or severe paravalvular regurgitation 2.0% (4/204) vs. 4.5% (4/89), P = 0.21) were similar in the two groups at 30 days after TAVR. These echocardiographic results were sustainable for one year. Conclusions::Chinese TAVR patients have more prevalent bicuspid morphology and large calcium volume of aortic root. Calcium is distributed mostly on the leaflet level. Compare with annular sizing strategy, downsize strategy provided a non-inferior device success rate and transcatheter heart valve hemodynamic performance in self-expanding TAVR procedure.
