Objective: To investigate the effect of recurrent laryngeal nerve (RLN) identification on the complications after total thyroidectomy and lobectomy. Methods: Total 134 consecutive patients undergoing total thyroidectomy or thyroid lobectomy from January 2003 to November 2004 were investigated retrospectively. Patients were divided into two groups: RLN identified (Group A) or not (Group B). The two groups were compared for RLN injury and hypocalcaemia. Results: The numbers of patients and nerves at risk were 71 and 129 in Group A, and 63 and 121 in Group B, respectively. RLN injury in Group A (0) was significantly lower than that in Group B (5[7.9%]) patients, 7 [5.8%] nerves) for the numbers of patients (P=-0.016) and nerves at risk (P=0.006). Temporary hypocalcaemia was significantly higher in Group A than in Group B (14 [24.1%] vs 6 [10.3%], P=0.049).Permanent complications in Group B were significantly higher than those in Group A (13 [20.6%] vs 4 [5.6%], P=0.009). Conclusion: RLN injury was prevented and permanent complications were decreased by identifying the whole course and branches of the recurrent laryngeal nerve during total thyroidectomy. 相似文献

This paper analyzes China’s attempt at maintaining and stabilizing the market framing of wind power development as ‘sustainable.’ Drawing on mixed data and new directions in the social studies of marketization, the analysis focuses on the Chinese government’s responses to the ‘quality crisis’ in the wind turbine industry. Employing five types of framing – goods, marketizing agencies, market encounters, price-setting, and market design and maintenance – the paper sheds light on flexible government interventions to steer the socio-technical assemblage around wind power towards a ‘turn to quality.’ In essence, this is a study of market construction in the context of Chinese wind power experiments. The paper contributes to new directions in market studies by (1) demonstrating the importance of attending to the contested algorithmic transformation of wind resources to wind power; (2) taking market studies to a transitional and developmental context, which renders marketization prone to constant overflowing; and (3) elucidating a particular Chinese model of experimental market construction ‘through embracing overflowing.’ The paper proposes new trajectories for future market studies with a focus on non-Western contexts, to reveal the wide variety of how marketization unfolds. 相似文献

Business students appreciate working on classroom projects that are both enjoyable and useful in preparing them for future careers. Promoting competition among project teams is also used as a method to motivate students. The Humanitarian Logistics Project (HLP) teaches undergraduate students the logistical implications of unsolicited material donations in disaster relief. To encourage competition, students are organized into teams of three and tasked with designing humanitarian public service announcements (PSAs) that improve their understanding of humanitarian issues in the general public. These announcements are then submitted to the national PSAid (Public Service Announcements for International Disasters) contest for American college students. The exercise is rigorous because it requires students to collect logistical data and use it to communicate the principle of smart compassion to the public in a creative fashion. Moreover, not only do students learn about topics related to humanitarian logistics by competing with other college students nation‐wide, but also do they make a socially responsible contribution to the public. Analysis of survey data shows that students’ learning outcomes from the HLP are significantly greater than those for other supply chain topics covered in class, and that student satisfaction with the HLP is high. 相似文献
