| 1 | Field trial of an HTS filter system on a CDMA base station显示文摘This paper presents the field trial results of a high temperature superconductor filter system (HTSFS) in a code division multiple access (CDMA) mobile communication base station (BTS) in Tangshan, China. The center frequency of the HTSFS is 830 MHz with 1.4% fractional bandwidth. The noise figure (NF) of the HTSFS, including connectors and cables, is 0.8 dB. The field trial results show that after the HTSFS was installed in the receiver front-end of a CDMA base station, the transmitting power of handset was decreased by 3.1 dB on average. Up to now, the HTSFS has been running steadily in the base station for more than 22 months, demonstrating the reliability and stability of the system. | YIN ZheSheng WEI Bin CAO BiSong WANG Xin GUO XuBo ZHANG XiaoPing GAO LongMa PIAO YunLong ZHU MaFeng LIANG Yong WANG Fan H.

| 2 | 慢性胰腺炎患者行包括临时支架的内镜下介入:一种有效的治疗显示文摘Objective. In the past 15 years there have been tremendous advances in endoscopic management of chronic pancreatitis (CP). However, the value of endoscopic pancreatic stenting is still debatable. Material and methods. In 98 patients suffering from symptomatic CP (84 M, 14 F, 49 ±12, age range 23-83 years) endotherapy including temporary stenting of the pancreatic duct was performed. After final stent removal, indicating the primary end-point of endotherapy, 96 patients were followed for 35 ±28 (8 days-111) months. All data were assessed retrospectively. Results. As well as other endoscopic procedures, a total of 358 prostheses were inserted in the pancreatic duct and left in place for 3 ±1(1 day-11) months. Total stent treatment time was 10 ±10 (6 days-49) months. At 46 ±27 (4-111) months after limited endotherapy, 57 patients had no need for secondary intervention, two-thirds were even without further pain sensations. In 22 patients, surgical treatment and in 17 patients further endoscopic therapy became necessary, which was significantly correlated with continued alcohol consumption. Conclusions. Temporary stent placement as a part of interventional endoscopic therapy in CP shows a high rate of technical and long-term clinical success, with no need for secondary treatment in a remarkable number of patients. Continued cessation of alcohol consumption supports the treatment benefit significantly. | Farnbacher M.J. Mühldorfer S. Wehler M. H.T. Schneider 赵菊辉 | 2006 | 世界核心医学期刊文摘(胃肠病学分册)2006，2，6： | 0 |
