Methods We conducted a prospective study on 120 patients with 260 previous stents implanted due to recurred suspicious symptoms of angina scheduled for invasive coronary angiography （ICA）, while DSCT were conducted using HPS mode. Results There was no significant impact of age, body mass index or heat rate （HR） on image quality （P 〉 0.05）, while HR variability had a slight impact on that （P 〈 0.05）. Sensitivity, specificity, positive predictive value （PPV）, negative predictive value （NPV） of DSCT in detection of in-stent restenosis （ISR） based per-patient were 92.3%, 96.7%, 88.9%, and 97.8%, respectively. And those based per-stent were 87%, 96.8%, 83.3%, and 97.7% with un-assessment stents, 97.4%, 99.5%, 97.4%, and 99.5% without un-assessment stents. There was significant differ- ence on sensitivity, specificity, PPV and NPV between diameter 〉 3.0 mm group （93.3%, 97.9%, 87.5%, and 98.9%） and diameter 〈 3.0 mm group （80%, 93.3%, 80.0%, and 93.3%） （P 〈 0.05）, and that between stent number 〉 3 group （82.3%, 77.8%, 66.7%, and 60%） with 〈 3 group （97.3%, 80%, 96.5%, and 75%）. The effective dose of DSCT （1.4 ± 0.5 mSv） is significantly less than that by invasive coronary angiography [4.0 ± 0.8 mSv （P 〈 0.01）]. Conclusion DSCT using HPS mode provides good diagnostic performance on stent patency with lower effective dose in patients with HR 〈 65 beats/rain.展开更多

Authentic presence requires three components： （1） honest exposition of a person＇s singular, essential being; （2） empathy towards the needs of other, distinct and separate from the self; and （3） mutual reciprocation, which means giving back or responding somewhat equitably to the other with whom the self is in communication, and accepting the same respondence from the other if afforded. The comprehension of Merleau-Ponty＇s ontology combined with Stanislavski＇s performance technique is uniquely suited to interpersonal communications in the ＇real world＇. Stanislavski＇s artistic vision demands an intensity of attentive involvement in order to achieve onstage authenticity. Merleau-Ponty provides supportive philosophical schematics, especially in his controversial but effective use of the expression ＇flesh＇. While this study may initially appear to focus on the artist, the development of interrelational skills is reliably applicable to anyone who desires to obtain a higher degree of authenticity in collaborative presence.展开更多
