浅谈粉尘接触量与矽肺发病的关系

目的 探讨粉尘接触量与矽肺发病的关系.方法 选择某大型矿山1975～1980年间工作1年以上的1 372名接尘工人进行队列研究,将队列成员按累积总粉尘接触量进行分层,分层统计矽肺患者人数及矽肺发病率.结果 追访到2007年底,检出矽肺459例(占33.5%),在累积总粉尘接触量达每年(87.7±64.8)mg/m<'3>时即发生矽肺.结论 累积总粉尘接触量与矽肺发生有明显的剂量关系,每年累积总粉尘接触量>150mg/m<'3>的矽肺发病率是每年累积总粉尘接触量<10 mg/m<'3>约155倍.     

寄宿学校餐具洗涤剂残留状况调查

有研究结果显示,餐具上残留的洗涤剂长期被摄入可在机体内蓄积,并对人体健康产生不良影响~([1]).为了解西宁市中、小学公用餐具洗涤剂残留状况,笔者于2008年6-8月对该地区6个中小学生寄宿场所公用餐具洗涤剂残留状况进行调查.     

吡那地尔预处理对缺氧/复氧性损伤时大鼠脑皮质线粒体结构功能的影响

越来越多的证据表明,线粒体功能障碍是导致脑缺氧直接损伤和延迟性神经元坏死的主要原因,同时也是启动细胞凋亡的关键[1,2].本研究采用大鼠脑缺氧/复氧模型,1从线粒体水平探讨缺氧/复氧时脑皮质神经元的损伤机制以及钾通道开放剂吡那地尔对此损伤的影响.     

肺心病急性发作期酸碱平衡失调(附278例次血气分析)

肺心病急性发作期病人可以合并多种酸碱平衡紊乱,且有变化快、类型复杂、混合型酸碱平衡紊乱发生率高的特点。本文通过对肺心病急性发作期患者278例次血气分析结果分析,以期找出规律,加深认识。 1 资料与方法 1.1 一般资料:全部资料为我院1994年1月～1997年10月收治的89例次肺心病急性发作期病人278例次血气分析结果,符合1997年全国肺心病专业会议修订的标准。     

内固定应用于脊柱结核治疗的安全性探讨

Objective To investigate the efficiency and safety of instrumentation to treat spinal tu-berculosis. Methods Fifty-one patients of spinal tuberculosis were treated with one-stage or two-stage de-hridement, strut autografting, and anterior or posterior instrumentation with screw rod system, combined with one-year triple agents postoperative antituberculous chemotherapy from April 1985 to May 2005. There were 6 in cervical spine, 19 in thoracic spine, 16 in thoracolumbar spine and 10 in lumbosacral spine. The level of the lesion were 6 cases for single vertebrae, 30 for two vertebrae, 11 for three vertebrae and 4 for more than four vertebrae. All patients were given triple agents antituberculous chemotherapy at least two weeks before operation. The operative procedures included cervical anterior approaches in 6 cases for debridement, fusion and plate-screw fixation, upper lateral transthoracic procedures for debridement, fusion and screw rod fixation in 11, posterior debridement, fusion and transpedicular screw system fixation in 6, two-stage anterior and posterior operation in 18 cases. The instrumentation included 6 Luque, 3 Z-plate, 8 TSRH, 5 Ventrofix, 4 Kenada, 5 Moss-Miami, 6 Isola, 3 CDH, 2 Caspaz, 2 C-D, 1 Zielke, 1 Dick, 1 Oriell, 1 Ozion, 1 Zephir, 1 Tenor, and 1 USS. Results All patients were followed up prospectively for 3.2 to 23.5 years postoperatively. The back pain was obviously relieved postoperatively. Patients with neurological function deficiency im-proved. The solid fusion was achieved in all patients, except one patient due to tuberculosis recurrence. The major complication included one sinus formation and one case with temporary deterioration of neurological function, recovered with appropriate treatment. Average preoperative kyphosis angle was 34.17°, and that was 10.45° immediately after surgery. There was a 3.2° loss of kyphosis correction during follow-up period. Con-clusion Spinal tuberculosis treated with instrumentation is effective and safe.     

一例绞窄性肠梗阻老年病人急诊手术麻醉

老年围术期并发症或死亡率较年轻人高3倍，其中2％的死亡率与麻醉有关。充分的术前估计与准备、适宜的麻醉方法、合理用药、加强术中监测是降低手术麻醉风险、安全度过围术期的重要措施。
