靶重建放大扫描对肺孤立性结节病变的诊断意义

目的：探讨靶重建放大扫描技术对肺孤立性结节病变的诊断价值。方法：对63例患者先行常规CT平扫，选定结节处为兴趣区，行薄层靶重建放大扫描，层厚、层距为2mm，FOV为160。结果：42例恶性病变中有37例表现为深分叶，占88．1％；21例良性病变中有15例表现为浅分叶，占71．4％。恶性结节中15例内部出现条状低密度支气管征；7例出现血管集中征；8例出现空泡征；病变内部出现液化坏死13例，其中恶性病变ll例。22例出现钙化，包括12例良性病变和10例恶性病变。2例错构瘤内均见小面积脂肪性低密度影。结论：靶重建放大扫描比普通CT扫描可提供更多的信息，对良恶性病变的鉴别诊断有一定价值。恶性病变大多数为深分叶，良性病变大多数为浅分叶或无分叶。     

医院图书馆与医务人员卫生法学教育

为了改变卫生人员和医学生的知识结构,自觉执行卫生法,培养适应新时代有道德、有文化、守纪律、高素质的卫生人员,必须要加强学习卫生法学教育。文章阐述了卫生法的概念,及其教育的意义,卫生法学在医疗实践中的作用;同时提出了图书馆如何配合医院开展卫生法学教育的措施,扩大藏书内容,开办法律讲座学习班,做好法律知识宣传工作,坚持以医教研为中心,深化服务质量。     

Is the Evaluation of the Global Quality of Life Determined by Emotional Status?

The present study investigated relationships between global QOL perceptions and well-being dimensions. Especially our goal was to evaluate the impact of generally recognised four broad dimensions of QOL (physical, functional, social and emotional well-being) on global QOL perceptions, additionally person's satisfaction with life achievements and economical situation were measured as well as social demographic variables. The subjects were a representative sample of Finns (n = 4613, from 25 to 65 years) of the FINRISK-97 study. Correlation coefficients and models of hierarchical regression indicated that physical, functional and social well-being as well as sociodemographic factors and satisfaction with life achievements are important factors of global QOL perceptions both among males and females. However percentages of variances explained with these measures were only moderately high, ranging from 1 to 10%. After measures of emotional well-being were entered into the models of hierarchical analyses of regression, variances explained grew dramatically over 20%. The results of the study indicated that global QOL judgements are likely to be based on current emotional state.     

经导管局部溶栓治疗髂-股静脉血栓:58例回顾性分析

目的　探讨经导管局部溶栓治疗髂 股静脉血栓的效果及临床应用中的有关问题。资料与方法　对 5 8例髂 股静脉血栓形成患者 (病程 <4周 4 5例 ,>4周 13例 ) ,采取经导管血栓局部灌注尿激酶 ,尿激酶先团注2 5 0 0 0 0U ,然后以 12 5 0 0 0～ 15 0 0 0 0U/h持续灌注。结果　全组溶栓治疗时间 4～ 5 6h ,平均 36h ,尿激酶用量75 0 0 0 0～ 72 5 0 0 0 0U ,平均 4 70 0 0 0 0U。阻塞段完全开通 (残存狭窄率 <30 % )者 30例 ,部分开通者 2 3例 ,无效 5例 ,有效率达 91.4 %。对残存狭窄率 >30 %的 2 3例 ,14例行经皮球囊血管成形术 (PTA)治疗 ,9例行PTA及内支架治疗。 6例溶栓前放置下腔静脉过滤器。本组无严重并发症及肺栓塞发生。结论　经导管血栓局部灌注尿激酶是治疗髂 股静脉血栓的安全、有效方法。溶栓术后继续肝素全身抗凝治疗可增强溶栓疗效     

Prenatal diagnosis of Werdnig Hoffmann disease in China

Objective To establish a means for prenatal prediction of spinal muscular atrophy (SMA) through survival motor neuron (SMN) gene deletion analysis and genetic counseling in families with a child affected with SMA.
Methods Genetic analysis for prenatal prediction of Werdnig-Hoffmann disease was performed in a at risk Chinese family by polymerase chain reaction (PCR)-single-strand conformation polymorphism (SSCP) in SMN gene exons 7 and 8.
Results The pregnancy was positive for the homozygous deletion of the SMN gene, thus the fetus was diagnosed as being affected and the pregnancy was terminated.
Conclusion This approach is fast and reliable for DNA-based prenatal diagnosis of Werdnig-Hoffmann disease.     

慢性鼻窦炎患儿家长疾病知识认知度调查

目的了解鼻窦炎患儿家长对儿童鼻窦炎相关知识的认知情况,为进一步加强卫生宣教、预防儿童鼻窦炎提供理论依据。方法对65名鼻窦炎患儿家长进行关于儿童鼻窦炎发病因素、临床表现、并发症以及对儿童生长发育影响等问题的问卷调查。结果调查显示95.4%的家长对儿童鼻窦炎知识缺乏了解,且知识获得途径单一。结论应通过各种途径加强儿童鼻窦炎知识的宣教,积极预防儿童鼻窦炎。

Fat and water separation in balanced steady-state free precession using the Dixon method.

In this work the feasibility of separating fat and water signals using the balanced steady-state free precession (SSFP) technique is demonstrated. The technique is based on the observation (Scheffler and Hennig, Magnetic Resonance in Medicine 2003;49:395-397) that at the nominal values of TE = TR/2 in SSFP imaging, phase coherence can be achieved at essentially only two orientations (0 degrees and 180 degrees ) relative to the RF pulses in the rotating frame, under the assumption of TR < T2, and independently of the SSFP angle. This property allows in-phase and out-of-phase SSFP images to be obtained by proper choices of the center frequency offset, and thus allows the Dixon subtraction method to be utilized for effective fat-water separation. The TR and frequency offset for optimal fat-water separation are derived from theories. Experimental results from healthy subjects, using a 3.0 Tesla system, show that nearly complete fat suppression can be accomplished.
