永清县城区小学生独生儿童身心健康状况的调查

随着计划生育这一基本国策的贯彻落实，独生子女在大中城市已占儿童总数的9096以上。有关他们的身心健康问题早已为社会各界所关注。为了解县城区独生儿童的身心健康状况，我们于2005年7月对我县城区第二小学的独生子女进行了调查，并以该校同班级非独生子女作为对照，试图找出他们不同于一般儿童的特殊问题，以引起家长、教师和保健部门的重视。     

1例严重电伤的术后护理

随着社会的发展，电能的应用日益广泛，因此电损伤的发生率亦随之增加。由于生活中，家用电器而造成的自然灾害，生产工作中意外事故的发生等，都具有很强的突发性，使受伤者心理震撼大，对蒙难时的惨境记忆深刻，承受着躯体和心理上的创伤与痛苦，严重影响着患者的身心健康。2003年8月12日，我科收治1例严重高压电击伤患者，经及时救治及精心护理而获得成功，未发生任何护理并发症。现将护理工作报告如下。

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.     

滥用抗生素致喉真菌病3例报告

喉部真菌病很少见,大多由口腔、咽部及鼻部真菌感染而继发。近年来,真菌病特别是深部真菌病的发病率有了明显的增加,其原因与大量抗生素的广泛应用有关。本文报告3例因滥用抗生素所致的喉真菌病,旨在使临床医生能够正确应用抗生素。1临床资料病例1:患者女,50岁。因声音嘶哑、咽     

人源性多肽pCM-19抗菌机制的初步研究

目的：初步分析人源性多肽pCM-19的抗菌作用机制。方法：利用荧光素掺入破损细胞膜的原理，采用流式荧光激活细胞分析（FACScan）和扫描电子显微镜分析pCM-19对靶菌膜的作用机制。结果：FACS分析法结果显示pCM-19处理后的大肠杆菌PI着染细菌比例明显高于未处理组，并且随作用时间的延长，PI着染BL-21菌比例增大，20min时达最高水平，20min以后反而降低；扫描电子显微镜观察到pCM-19处理后的大肠杆菌有明显的表面形态学的改变，如细菌体积缩小、细菌表面出现皱缩、凹陷似有孔洞形成。结论：人源性多肽pCM-19可能作用于细菌细胞壁和（或）细胞膜，通过改变其通透性而发挥杀菌作用。     

MR频谱检测乳酸的脉冲序列优化研究

目的通过改变一系列脉冲序列参数，以利于乳酸的最佳检测与定量分析。方法制作含乳酸玻璃模型。改变一系列的MR脉冲序列参数，应用点解析频谱序列(point resolved spectroscopy，PRESS)和激励回波序列(stimulated echo acquisition，STEAM)获得乳酸模型的相应频谱。另外，对12例脑病变患者和2例健康志愿者进行磁共振频谱检查，测量出每个波峰的峰高，并绘出序列变化曲线图。结果STEAM各波峰的峰向与PRESS序列一致，但STEAM各峰高均低于同等条件的PRESS峰。随着TE时间的延长，用乳酸模型测出的乳酸峰的峰高一序列曲线图呈波浪状变化，正向双峰在TE=26、270ms时共振波幅达到最大绝对值，负向双峰在TE=135～160ms之间达到最大绝对值。脑病变患者和健康志愿者的扫描结果表明，乳酸峰在优化的序列高于非优化的序列。结论优化的脉冲序列更有利于乳酸的检测与定量分析。
