相对头盆不称为指征的剖宫产80例临床分析

对我科１９９７年１－１１月间因相对头盆不称而施行剖宫产手术者８０例进行分析。结果：６５例诊断处理正确。诊断正确率为８１．２５％。另１５例中，过早诊断相对头盆不称者９例。提示：在产程中及时正确的诊断相对头盆不称，并允许其进行充分的试产。在产程中予以正确的处理，是降低剖宫产率，提高产科质量的关键。

影像本科临床实习带教要点的探讨

目的 使学生能在有效的临床实习时间里学到更多的临床应用知识。方法 掌握好学生进入临床实习后，几个不同阶段(初到、中途、后期)应注意养成和熟悉的关键问题，使其有序的从书本知识过渡到临床实践，从而加深对理论知识的升华，为将来顺利过渡和进入临床工作打下坚实的基础。结果 学生能在初期最短时间里熟悉有关的影像检查和诊断工作程序，从而顺利开展实习工作；在中期充分利用熟悉的环境和与老师紧密的接触，深入进行各系统疾病的影像检查、诊断及鉴别诊断的学习；后期是比较熟悉但也是最容易放松的阶段，掌握得好，则学业有成，否则就半途而废，作为带教老师应该特别注意引导和把握好这一关。结论 总结连续六届学员实习成绩以及跟踪学生毕业后工作情况调查反馈，认为这是一项行之有效的临床实习教学方法。     

产妇出院后继续母乳喂养的健康教育

产妇出院后的健康教育作为医院健康教育内容的延伸 ,在社区健康教育中发挥着不可缺少的重要作用。本文对 2 0 0 0年 6月至 2 0 0 2年 6月间在河北省承德医学院附属医院产科出院的市区内的产妇随机选取 3 96名 ,进行首次出院后母乳喂养的健康教育后再由社区妇幼保健医师进行入户随访 ,并对产妇及家属继续进行母乳喂养的健康教育 ,同时对不正确的母乳喂养观念与行为进行相应的干预 ,使产妇出院后母乳喂养率由健康教育前的 51 77%提高到90 40 % ,取得了良好的效益。对象与方法1 对象　采用随机抽样的方法选取 2 0 0 0年 6月至 2 0 0 2年 6月…     

河北省布鲁氏菌病流行现状及防治对策探讨

布鲁氏菌病(以下简称布病)在河北省流行历史较长,据资料记载,30年代初某县就有布病爆发流行,70年代中后期全省布病病情稳定,近年由于农牧业发展迅速,饲养量增加,饲养形式改变,牲畜交易频繁等因素影响,致使布病又呈局部爆发流行,本文通过对全省布病流行现状分析及新形势下防治对策的探讨,进一步控制布病流行提供了参考依据。     

免疫斑点法检测布氏菌病人血清中抗原的初步应用

免疫斑点试验是一种酶联免疫分析新技术,应用硝基纤维素纸结合蛋白质,比聚苯乙烯吸附牢固这一特点,来替代聚乙烯作固体载体,据报道,对实验动物绵羊布氏菌病的抗原检测,具有可靠性,特异性强,敏感性高等优点,但仍有操作烦杂,有非特异干优因素,目前用斑点——ELISA双抗夹心法检测病人血清抗原的报道甚少,作者以硝酸纤维膜(NC)作为载体,检测了36例布病患者及43例因S_2菌苗感染抗体阳性血清(同时作SAT和RBPT抗体测定为参考),结果如下。1 实验材料与方法 材料:硝酸纤维膜,直径0.4cm,北京化工学校附属工厂生产,包被抗体自制,以牛型104M布氏菌     

京宝口服液质量标准研究

应用模拟低剂量法行新生儿头颅CT扫描

Objective To determine the effects of dose reduction on multi-slice spiral CT(MSCT) of neonatal head and assess the lowest possible radiation for acceptable clinical images.Methods Fifty-seven newborns suspected intracranial hemorrhage were entered into the study and underwent MSCT scans.Original images at three anatomic levels (posterior fossa, basal ganglia, centrum semiovale) were collected and synthetic noise was added so as to simulate dose reductions of 25%, 40%, 50% and 70%, respectively by using the noise addition tool.A total of 855 image data sets were obtained for the 57 patients.Original and simulated dose-reduction scan images were analyzed.Image noise and image quality were assessed by two independent experienced pediatric radiologists using diagnostic acceptability score, subjective image noise score on a 5-peint scale and objective noise index.Image noise was measured by respectively placing region of interest (ROI) at cerebellum, thalamus and corona radiata of 3 different slices.And the noise index and mean value was calculated.The degree of inter-observer concordance was determined by Kappa statistical analysis.The Spearman statistical correlations between the noise index and diagnostic acceptability score were performed.Results On the images of original dose and simulated dose reductions of 25%, 40%, 50% and 70%, the diagnostic acceptability was 4.47±0.51, 3.96±0.33, 3.21±0.45, 2.92±0.32, and 1.85±0.57, respectively,the subjective image scores were 1.62±0.48, 1.99±0.48, 2.76±0.81, 3.19±0.67, and 4.27±0.54, respectively, the noise index were 1.90±0.19, 2.17±0.20.2.44± 0.25, 2.68±0.28, and 3.37±0.39, respectively.The two radiologists had good intembserver agreement for diagnostic acceptability (K=0.860, P=0.017) and for image noise scoff ng (K=0.630, P=0.022).There was significant statistical correlation between image noise index and diagnostic acceptability (r= 0.826,P=0.001).At 40% dose reduction to the standard protocol, the noise index was 2.44 and the image quality score was 3.21 which were considered clinically acceptable.Conclusion The study revealed that acceptable imagos could be obtained with mean noise index of 2.44 and 40% dose reduction.
