| 1 | Selective sphincteroplasty of the papilla in cases at risk due to atypical anatomy显示文摘AIM: To analyze the indications, effi cacy and safety of sphincteroplasty in our centre. METHODS: A retrospective study of sphincteroplasty in 53 cases of papilla at high risk was performed in 2004-2006. The procedure consisted of duodenoscopy with Olympus TJF 145 Videoduodenoscope, approach to the biliary tract using a catheter with a guidewire, and dilatation of the papilla with a dilatation balloon catheter using a syringe with a manometer for control of the fi lling pressure. RESULTS: The indications included intradiverticular papilla in 26 patients (49/), stenosis of a previous sphincterotomy in 19 patients (35.8/), small size of the papilla in 4 patients (7.5/), Billroth Ⅱ gastrectomy in 3 patients (5.6/), and coagulopathy in one patient (1.9/). The efficacy was 97.8/, with all the calculi extracted from the common bile duct in 84.4/ of the patients, even though 21 of the patients (39.6/) had calculi with a diameter equal to or greater than 10 mm. Seven patients (13.2/) presented complications: haemorrhage in 1 patient (1.9/) and mild pancreatitis in 6 patients (11.3/). The mean hospital stay in case of complications was of 3 ± 0.63 d. CONCLUSION: Sphincteroplasty is highly effective, with a complication rate similar to that of sphincterotomy, furthermore, the complications are of low clinical importance. The use of the 10 mm balloon makes it possible to extract calculi with a diameter of over 15 mm and to extract more than 3 calculi without increasing the rate of complications and reduces the need to resort tolithotripsy or rescue sphincterotomy. | F Mugica G Urdapilleta A Castiella A Berbiela F Alzate E Zapata L Zubiaurre P Lopez JI Arenas | 2007 | World Journal of Gastroenterology2007，13，22： | 5 |
| 2 | 中阿40m射电望远镜选址与电磁环境监测显示文摘优良站址的选择是射电望远镜完成既定科学目标并实现高效运行的重要保障。影响射电望远镜选址的主要因素包括电磁环境、水文、气象、地质条件、隔离性与可及性等。对于射电天文观测而言,来自宇宙天体的射电信号往往极其微弱,对望远镜系统及设备的灵敏度要求极高。然而,随着人类活动的不断加强,人们日常工作和生活中使用的电子通讯设备越来越多,无线电干扰源呈爆炸式涌现。在射电望远镜选址工作中,进行电磁环境监测,选择一个电磁环境良好的站址,对于射电望远镜实现常规观测运行、获取有效数据资料至关重要。同时,电磁环境监测结果也是射电望远镜接收机系统研制、站址电磁环境及无线电宁静区立法保护的重要依据。中阿天文学者和技术人员历时1年半完成了16个候选站址的初步勘察,并对优选出的3个主要候选站址进行了深入细致的电磁环境监测工作,获得了大量可靠数据。中阿双方依据电磁环境监测结果并结合各主要候选站址的水文、气象、地质及道路等条件,最终将位于Talacasto戈壁的3号候选站址确定为中阿CART射电望远镜的建设站点。 | 赵卫普 李建斌 李金增 孙建民 齐力 罗滔 马晓耘 莫铠玮 李鹏程 夏跃兵 MALLAMACI C C PODESTA R C PACHECO A M ACTIS E CASTRO J I ALVIS R H LOPEZ C E FRANCILE C PODESTA F PEREZ J | 2014 | 天文学进展2014，32，3： | 4 |
