广东省梅县重点人群碘营养状况调查分析

Objective To estimate the present salt iodine content and iodine nutrition need of high risk population of iodine deficiency disorder in Meixian County. Methods Each primary school was selected from urban and rural areas(Xiyang Town, 20 kilometers away from Meixian County), the goiter rate of 8 to 10 year-old students was examined and urinary iodine and household salt iodine was sampled. Twenty to 40 year-old women of childbearing age nearby schools around the urban and villages around Xiyang Town were selected to collect their urine and salt samples. At urban hospitals and rural health centers, 0 to 2 year-old infant urine samples were collected, Thyroid gland was palpated and urinary iodine was determined by iodine in urine by As3+-Ce4+catalytic spectrophotometry, salt iodine was determined by direct titration. Results The goiter rates of 8 to 10 year-old students were 1.5 % (3/200), 1.0% (1/100) for the urban area and 2.0% (2/100) for rural area. Median of urinary iodine in 8 to 10 year-old students, infants, women of childbearing age averaged at 237.1 μg/L and 280.1, 234.7,187.6 μg/L respectively, with each being 287.4,245.0,205.5 μg/L in urban area and 278.9,228.5,176.4 μg/L in rural area. Women of childbearing age had a higher percentage of urinary iodine < 50.0 μg/L than students,students had a higher percentage than infants, each being 7.5%(15/200), 4.5%(9/200), 4.0%(4/100). The ration of urinary iodine > 300.0 μg/L was more in infants than in students, that in students was more than that in women of childbearing age, each being 33.0% (33/100), 30.0% (60/200),22.5% (45/200). The median of salt iodine was 27.2 mg/kg. The coverage of iodized salt was 100.0%(400/400). Ninty-seven percent(194/200) and 96.0% (192/200) of qualified iodized salt were consumed in urban area and in rural area. Conclusions The amount of iodine added to salt meets the requirement in the 3 kinds population risk of iodine deficiency disorder. But a higher iodine status has been found out in students and infants. It is reasonable to decrease the present salt iodine content.

碘对比剂在CT检查中的应用

我院自 1994年使用CT检查以来 ,需增强检查者的比例越来越高。增强检查确实提供了CT平扫不可替代的诊断信息 ,但是碘对比剂的副作用却令人担忧 ,因此 ,CT室的护理人员应认真做好对患者的筛选、敏试工作 ,严格掌握禁忌证 ,加强对副反应的预防性措施及意外抢救工作 ,合理使用对比剂 ,现将我院应用碘对比剂的方法介绍如下。1　严格掌握禁忌证严重的甲状腺功能亢进、失代偿性心肌功能不全者禁忌。妊娠及急性盆腔炎症时禁行子宫输卵管造影。2　认真筛选高危因素有碘造影剂过敏、严重肝肾功能损害、心脏和循环功能不全、肺气肿、体质极差者 ,重…     

巧用Ⅱ型安尔碘清除残留的骨水泥

骨水泥是骨关节手术中常用的填充材料，搅拌后黏稠，凝固迅速，易附着于搅拌器皿及手术器械而不易除去，用器械强行刮除已干涸的骨水泥会造成碎屑飞溅，影响器械台面整洁，若在骨水泥尚未完全硬化时用0．2％的Ⅱ型安尔碘棉球擦拭，即可轻松快速彻底清洁手术用物上的骨水泥。此法简便快捷，对器械无损伤，对环境及患者无害，值得推广应用。     

Beyond冷光美白术的护理配合

随着人们生活水平的日益提高，对美的要求也越来越高。牙齿美自治疗经历了氧化物温热外漂白法、家庭漂白法、激光漂白法、树脂贴面、烤瓷牙修复等过程。但它们都不同程度地存在美白效果不理想、稳定性差或对牙齿有损害等缺点。Beyond冷光美白法由于其使用安全，美白效果显著，操作时间短，成为牙齿美自治疗新宠^[1]。[第一段]
