Radionuclide imaging in patients with amputations of the lower leg: typical imaging patterns in five cases

Amputation of the lower leg is not uncommon in elderly patients with chronic infections or vascular problems of the leg and foot, and most often it is performed below the knee or on the distal part of the lower leg (i.e., Syme's amputation). After operation, healing disorders with or without infection can occur, and usually structural imaging methods are performed for diagnosis. Radionuclide imaging using a combination of bone scans and infection scintigraphy can help to identify bone and soft tissue infection. Interpreting radionuclide scans is difficult, because imaging findings after amputation may depend not only on the level of resection and the disease investigated but also on the time that has elapsed since surgery. Typical imaging patterns of bone or infection scintigraphy of five patients are described     

隔药灸治疗寒凝型痛经的疗效及对PGF2α、PGE2影响

目的探讨隔药灸治疗寒凝型痛经的作用机制。方法把60例寒凝型痛经患者按随机数字表分为两组,每组30例,隔药灸组采用隔药灸神阙穴,西药组采用内服西药,并设正常空白组30例不作任何治疗。结果隔药灸组总有效率（96．7％）优于西药组（83．3%）（P〈0．05）。隔药灸组治疗后PGF2α、PGEz与西药组比较差异有统计学意义（P〈0．01）。结论隔药灸治疗寒凝型痛经的疗效机制与调节PGF2α及PGE2有关,即可降低经期外周血PGF2α含量,升高PGE2含量。
