This study is tocompare changes in HRQL six months after hospital discharge between NSTE-ACS pa-tients who underwent either PCI or CABG.Methods HRQL was assessed using the Seattle angina questionnaire at admission and six months after discharge in 1012 consecutive patients with NSTE-ACS. To assess associations of PCI and CABG with HRQL changes, logistic regression models were constructed treating changes in the score of each dimension of the Seattle angina question-naire as dependent variables.Results Although both the PCI and CABG groups experienced angina relief and other improvements at 6-month follow-up （P〈0.001）, the CABG relative to PCI group showed more significant improvements in angina frequency （P= 0.044） and quality of life （P= 0.028）. In multivariable logistic analysis, CABG also was an independent predictor for both im-provement of angina frequency （OR： 1.62, 95%CI： 1.09-4.63,P= 0.042） and quality of life （OR： 2.04, 95%CI： 1.26-6.92,P= 0.038） relative to PCI.Conclusions In patients with NSTE-ACS, both PCI and CABG provide great improvement in disease-specific health status at six months, with that of CABG being more prominent in terms of angina frequency and quality of life.展开更多

China (AQSIQ). The leaders in charge of theState Council Office of Northeast Vitalization and the Provincial Office of Vitalization ofLiaoning, Jilin and Heilongjiang were invited to attend the forum. At the forum, Director of AQSIQLi Changjiang made active response to the issues surrounding 'how the central government policy ofvitalizing Northeast can be fulfilled' and 'how the departments of quality inspection can fulfilltheir duty and play an active role'.展开更多

It starts with the introduction of the importance of learning English, then it reveals the qualities and useful strategies that a teacher of English should master if he or she wants to make his or her lessons successful. It also conducts the analysis of how these tactics interact in the classroom teaching. The paper concludes that examining effective ways of teaching is useful in helping teachers either in their academic field or in their professional development.展开更多
