Fibrous metaphyseal defects — determination of their origin and natural history using a radiomorphological study

The radiomorphological appearance of fibrous metaphyseal defects (FMDs) is demonstrated by long-term follow-up studies. A characteristic radiomorphological course rather than a typical single appearance can be established. These findings correlate well with the duration of these tumor-like lesions; therefore, the radiological findings allow conclusions to be made about the age of a fibrous metaphyseal defect. In addition, the characteristic locations of FMDs will be explained in respect of their origins at insertions of tendons and ligaments.     

评价酶联免疫检测血清CYFRA21—1对非小细胞肺癌的诊断价值

目的评价检测ＣＹＦＲＡ２１┐１对非小细胞肺癌的诊断价值。方法用ＥＬＩＳＡ法测定７０例肺癌（ＬＣ）其中４７例非小细胞肺癌（ＮＳＣＬＣ），３例小细胞肺癌（ＳＣＬＣ）和２０例未分型肺癌、６４例肺部良性疾病患者及４０例健康人血清ＣＹＦＲＡ２１┐１浓度。试验的诊断性能用相对操作特征（ＲＯＣ）分析法估测之。结果测得全阈诊断准确率（ＯｖｅｒａｌＤｉａｇ┐ｎｏｓｔｉｃＡｃｃｕｒａｃｉｅｓ）ＬＣ为０．７５、ＮＳＣＬＣ为０．７６，ＳＱＣ为０．８３，ＡＤＥ为０．６７和ＳＣＬＣ为０．３８。在相应于特异性为０．９５的界定值３．４７μｇ／Ｌ处，各型的灵敏度分别为ＳＱＣ０．６２，ＬＣ０．５３，ＮＳＣＬＣ０．５１，ＡＤＥ０．４８和ＳＣＬＣ０．００。结论结果显示ＣＹＦＲＡ２１┐１是ＮＳＣＬＣ较灵敏和特异的一个标志物。未观察到ＴＮＭ各期间该标志物的平均水平有明显的差异；然而异常升高水平的患者的比例随病期的进展而显著增加，提示一系列检测ＣＹＦＲＡ２１┐１水平可能有助于监查ＮＳＣＬＣ患者的疗效。

Viewer-centred and object-centred coding of heads in the macaque temporal cortex

Summary An investigation was made into the sensitivity of cells in the macaque superior temporal sulcus (STS) to the sight of different perspective views of the head. This allowed assessment of (a) whether coding was viewer-centred (view specific) or object-centred (view invariant) and (b) whether viewer-centred cells were preferentially tuned to characteristic views of the head. The majority of cells (110) were found to be viewer-centred and exhibited unimodal tuning to one view. 5 cells displayed object-centred coding responding equally to all views of the head. A further 5 cells showed mixed properties, responding to all views of the head but also discriminating between views. 6 out of 56 viewer and object-centred cells exhibited selectivity for face identity or species. Tuning to view varied in sharpness. For most (54/73) cells the angle of perspective rotation reducing response to half maximal was 45–70° but for 19/73 it was >90°. More cells were optimally tuned to characteristic views of the head (the full face or profile) than to other views. Some cells were, however, found tuned to intermediate views throughout the full 360 degree range. This coding of many distinct head views may have a role in the analysis of social signals based on the interpretation of the direction of other individuals' attention.     

Clinical applications of characteristic frequency measurements: preliminaryin vivo study

In vivo electrical impedance tomography images have been available for some years, and most of them show variation in impedance amplitude between two different states, for example between inspiration and expiration of the lungs. A refinement of the tomography technique has made it possible to show images of the complex impedance of the body. If several frequencies are used, more information on the investigated tissues can be collected, and new areas made available for investigation. It has been shown that tissues exhibit a characteristic frequency that can be derived from the maximum magnitude of the (negative) reactance. The characteristic frequency-related images can be calculated from several imaginary part curves obtained using the back-projection technique. The paper shows in vivo impedance spectra from different parts of the body, determines the characteristic frequency of the different in vivo measurements and suggests different applications of characteristic frequency imaging. Several data sets are collected to show the reproducibility of the measurements.     

肺炎性假瘤24例的临床X线误诊分析

目的探讨肺炎性假瘤的临床与X线误诊原因;方法依据临床与X线资料分析;结果均有不同程度的呼吸道症状,有14例痰中带血丝。肿块直径小于4cm11例,密度高而均匀,边缘光整,误诊为肺良性肿瘤。肿块直径大于4cm13例,密度不太均,边缘有分叶或有毛刺,误诊为肺癌;结论临床上多无急慢性感染症状,本病与其他占位性病变极相似,缺少特征,对本病缺乏认识是导致误诊的主要原因。肿块邻近胸膜,边缘出现尖角征,动态变化缓慢这3点对提高正确诊断率有独特的价值。

上海市黄浦区1990—2013年肺结核疫情分析

[目的] 了解上海市黄浦区肺结核疫情的流行特征,评价防治工作的成效。[方法] 运用生态学研究方法对1990-2013年黄浦区肺结核流行特征和趋势进行分析。[结果] 1990-2013年,黄浦区肺结核的平均发病率为37.37/10万,发病总体呈逐渐下降趋势;平均死亡率为0.47/10万。老年男性(65岁以上)人群的发病率较高。病例中离退人员、工人、家务及待业者所占比例最高。[结论] 1990-2013年,肺结核防控的效果显著。但大众的防控知识和意识欠缺、不规范治疗、耐药率高、流动人口众多等都对结核病防治带来挑战。结核病患者的诊断、治疗、管理仍需完善。
