儿童肺炎支原体感染状况分析

目的 探讨儿童的肺炎支原体(MP)感染现状及早期诊断的意义。方法 检测181例就诊儿童血液标本分析MP感染的状况。结果 肺炎支原体感染率为29.8％;男性患儿MP检测阳性率(35.7％)明显高于女性患儿(16.4％)(P<0.01);5岁以下患儿阳性率超过50％,且有3例婴儿检测阳性;10-12月份支原体肺炎发病率明显增加,占全年的40.7％。结论 针对儿童支原体肺炎的发病情况,早诊断,早治疗,利于患儿尽早康复,防止肺部病变迁延及肺外并发症的发生。     

Effect of estrogen on calcium homeostasis and pituitary hormones in the growing chick

An experiment was carried out to investigate the effect of a range of estradiol (E2) doses (0.1-6.5 micrograms/g body wt/day) on vitamin D metabolism and the plasma levels of growth hormone (GH) and prolactin (PRL) in the growing chick. Doses of 0.5-0.7 microgram/g E2, which are insufficient to raise the plasma calcium level, did induce an increase in growth rate, an increase in 25-hydroxyvitamin D 1 alpha-hydroxylase (1-hydroxylase) and 24-hydroxylase activities, and an increase in plasma GH level. These parameters leveled off or fell over the dose range 1-2 micrograms/g E2 but there was evidence of a second peak in 1-hydroxylase activity at 6 micrograms/g E2. At this high dose rate, the plasma Ca level rose to 8 mM, as it does in the laying hen; 24-hydroxylase activity, growth rate, and plasma GH and plasma PRL levels all decreased. It was concluded that the dose response to estrogen in the growing chick is not linear and, in the case of 1-hydroxylase activity, may even be biphasic.     

创伤性休克病人的早期急救护理体会

目的:讨论在院前和急诊科对创伤性休克病人施行早期急救护理,对挽救病人的生命及伤情预后有重要的意义.方法:对我科1997年2月至2001年4月27例创伤性休克病人进行早期,快速,积极的补液,输血增加有效循环量,监测生命体征等综合性抢救治疗与护理措施.结果:经早期积极急救护理,26例病人收缩压维持在60mmHg以上,意识清醒,脉搏有力,转入手术室或专科治疗,1例病人伤势严重抢救无效死亡.结论:创伤性休克病人,伤势复杂,死亡率高,伤后早期院前与急诊科的有效救护,是提高抢救成功率的关键.     

高血压的社区管理与医院内科门诊管理效果比较

目的 评价健康教育在社区高血压患者管理中的效果。方法 随机抽取北京复兴医院月坛社区卫生服务中心管理的高血压患者603例作为研究对象,以同期该院三里河内科门诊就诊的高血压患者617例作为对照,进行血压测量和问卷调查。结果 社区高血压患者高血压知识知晓率明显好于内科门诊高血压患者(P<0.01);其生活方式(遵医行为、体育锻炼、食盐量等)较好;血压控制情况也好于门诊患者(P<0.01)。结论 规范、定期的健康教育可以提高高血压患者对高血压知识的知晓情况,改善高血压患者的不良行为习惯;利用社区卫生服务站固定的合作关系及新型医患模式有利于健康教育、健康知识普及和取得治疗成效。     

BS15PFACILITATING NATIONAL CONSISTENCY IN BREAST CANCER DATA COLLECTION

In Australia there is currently no consistent approach to collecting breast cancer specific data. The National Health Data Dictionary (NHDD) recommends a core set of generic data items for clinical cancer registration. However this list does not include the more detailed items required by specific tumour streams. The NBCC has developed a supplementary set of Breast Specific Data Items and definitions to serve as a guide for specialist breast cancer data collection in Australia. A multidisciplinary Working Group comprising clinical and consumer representation, including three breast surgeons, identified 16 breast specific data items for collection. The items are designed to align with items collected through the RACS National Breast Cancer Audit and leading cancer centres. A range of items from patient data (menopausal status), diagnostic data (HER2 status, sentinel lymph node), treatment (surgical margin clearance and involvement), and breast reconstruction are included. The data items are recommended as best practice for breast cancer specific data collection and aim to facilitate national consistency in defining, recording, and monitoring information about patients with breast cancer. This national approach will contribute to improved patient outcomes by informing planning, quality improvement and evaluation strategies for cancer services. The items are currently being piloted in two sites in NSW and will be available nationally in late 2007.     

妊高征与眼底视网膜病变的临床探讨

目的 :探讨妊高征患者临床特征与视网膜病变的关系。方法 :观察 2 2 0例妊高征患者的眼底情况。结果 :视网膜病变与水肿关系不密切 ,与平均动脉压、蛋白尿的严重程度、病程及红细胞压积有密切关系 ;有眼底改变者 118例 ,占 5 0 .3%。结论 :眼底镜检查是临床上借以了解视网膜血管的常用方法 ,并可反映妊高征病情的程度 ,为产程处理提供依据     

现阶段县级卫校在初级卫生保健中的作用探析

依据乡村医生人力结构现状调查结果,就现阶段县级卫校在初级卫生保健中的作用及今后面向乡村医生办学的可行性作了具体的分析和探讨。结论是:提高质量,加强对在岗乡医进行系统化正规中专层次的职后复训,应是县级卫校今后1O年的最主要的任务。     

线宽增量法及其在生物材料发射光谱分析中的应用

作者利用交流电弧和光栅摄谱仪组装了能够绘制谱线轮廓曲线和准确测定谱线宽度的记录仪,用线宽增量法对生物材料(拟血清)中的主要成分Ca和微量元素Cu进行了测定。与黑度法相比,本实验结果的线性好,误差小,再现性有所提高。这些结果表明,用上述仪器装置和线宽增量法进行生物材料含量分析优于黑度法。     

肝病患者肝组织中丙型肝炎病毒感染的初步研究

采用直接酶标记法对174例慢性肝炎、重症肝炎和肝癌组织中的HCV抗原进行了检测,HCV 抗原的检出率分别为10.71％、8.10％和2.68％。表明在我国慢性和重症肝病中存在HCV的感染。通过对HCV与HBV 感染关系的研究,发现肝内HBV 标志阳性和阴性者HCV抗原的检出率无明显差异,说明HCV感染与HBV感染之间似无明显关系。
