某儿童医院10年临床报告细菌性痢疾的流行病学特征

目的探讨细菌性痢疾(以下简称菌痢)近10年流行特点。方法对10年来收集的全院各科上报的菌痢进行回顾性分析。结果1993-2002年报告菌痢10861例,占传染病报告总数的62.92%,传染科门诊量占全院门诊百分比的年变化为8.54%～4.33%;菌痢发病占传染科门诊的年比率变化为1.05%～3.45%;<1岁、1～3岁、4～6岁、7～9岁、≥10岁5个年龄组,各组之间菌痢检出率差异有统计学意义,1～3岁组检出率最高;细菌性痢疾每年4月检出率开始上升,8月达最高,11月检出率恢复到上升前水平;不同性别的儿童检出率差异有统计学意义,男童明显高于女童。结论细菌性痢疾检出年龄特点为婴幼儿最高,随年龄增长,发病逐渐减少;发病高峰季节向春秋季扩展。     

2003年胶州市苯作业场所空气中苯的危害监测

近几年来随着青岛地区经济的发展,大量鞋革箱包及玩具制造,家具制造企业涌现于胶州.在这些企业里,普遍使用含有苯的强挥发性胶水粘合剂.苯系化合物已被WHO确定为强致癌性物质，由于苯系物属芳香烃类，无色透明易挥发，使人一时不易警觉其毒性。人在短时间内吸入高浓度的苯，会出现中枢神经麻醉的症状，轻者头晕、胸闷、恶心、乏力、呕吐。     

苯环喹溴铵抗炎止痒作用的初步观察*

目的：初步研究苯环喹溴铵的抗炎止痒作用。方法：在二甲苯诱导小鼠耳肿胀模型、冰醋酸诱发小鼠毛细血管通透性亢进模型和磷酸组胺致痒豚鼠模型上，观察苯环喹溴铵的抗炎和止痒作用。结果：苯环喹溴铵能较好地抑制二甲苯所致的炎症反应，降低冰醋酸诱发的小鼠毛细血管通透性增加，缓解磷酸组胺的致痒作用，并呈一定的量效关系。结论：苯环喹溴铵具有较好的抗炎止痒作用。     

The care of advanced cancer exclusive of the relief of pain by drugs

A régime for the care of far advanced cancer patients is elaborated.The following considerations in therapy are discussed: the psychologic approach; nursing care; bedsores; ulcers; odors; discharges; the peculiarities of abdominal cancer; fistulae from hollow viscera; hemorrhage; intractable pain; palliative operations.The importance of treating the exact cause of the discomfort rather than loading the patient with narcotics, is emphasized.     

Mechanical Testing of Seven Fixation Methods for Generation of Compression Across a Midtarsal Osteotomy: A Comparison of Internal and External Fixation Devices

The purpose of this study was to assess 7 methods of fixation for a midtarsal osteotomy. Polyurethane foam models (N = 6) and cadaver specimens (N = 4-7) were used to examine the force generated by the different constructs of fixation. A midtarsal osteotomy was performed on each specimen in the test groups. The osteotomies were fixated either with 2 parallel 0.062-in Kirschner wires and 40-mm-long, 4-mm partially threaded, cancellous, cannulated titanium screws, an external ring fixator (frame), a frame with wires tensioned (tension), a frame with wires tensioned and compressed toward the osteotomy (tension and compression), a frame with tension, compression, and parallel Kirschner wires, or a frame with tension, compression, and two 4.0 cannulated parallel screws, respectively. Each model was fixated, and the force generated by the construct across the osteotomy was recorded via the use of pressure-sensitive film. Statistical analysis of the data in the polyurethane foam group determined that the use of frame with tension, compression, and two 4.0 parallel cannulated screws was statistically superior to 1) frame, 2) frame with tension, 3) 2 parallel Kirschner wires, 4) two 4.0 cannulated parallel screws, and 5) frame with tension and compression. A cadaver study determined that the frame with tension, compression, and 2 parallel Kirschner wires was statistically superior to 1) frame and 2) two parallel Kirschner wires. These findings suggest that there is a difference in the force generated by the type of fixation construct across a midtarsal osteotomy.
