On the Limitations of Therapy Manuals

While the benefits of training manuals can hardly be questioned, they are exceedingly limited in reducing variability attributed to the "therapist factor." We propose that manuals provide a useful outline of the general principles of a therapeutic approach, but can only reduce therapist variability at the expense of other essential therapeutic phenomena. Manuals cannot adequately convey, for example, how the effective therapist functions as a model of adult living and as a person who provides guidance. We suggest that such an experience cannot readily be packaged in manualized form, though manuals may serve as a useful beginning. Recommendations for therapist manualized training include greater attention to the subtleties of human relationships and adequately conveying that any technique is effective only when catalysed by a living, relational process.     

溴氰菊酯对白纹伊蚊（Aedesalbopictus）C6／36细胞株的细胞遗传学效应

本研究选择１０μｇ／ｍｌ、２０μｇ／ｍｌ、４０μｇ／ｍｌ浓度的溴氰菊酯处理白纹伊蚊Ｃ６／３６细胞，以ＭＭＣ作为阳性对照物，观察溴氰菊酯处理２４ｈ后对Ｃ６／３６细胞染色体畸变率和姐妹染色单体互换（ＳＣＥ）频率的影响。结果显示，三个浓度的溴氰菊酯对Ｃ６／３６细胞染色体畸变率均没有显著影响（Ｐ＜０．０５）；溴氰菊酯浓度在４０μｇ／ｍｌ时可诱导Ｃ６／３６细胞ＳＣＥ频率轻度增高（Ｐ＞０．０５），而溴氰菊酯浓度在１０μｇ／ｍｌ、２０μｇ／ｍｌ时，对Ｃ６／３６细胞ＳＣＥ频率没有诱导作用。表明溴氰菊酯对Ｃ６／３６细胞的遗传学效应较弱     

慢性低氧大鼠肺动脉内皮素mRNA的表达及定位

目的：探讨慢性低氧大鼠肺动脉内皮素－1基因表达及分布。方法：采用生物素标记cRNA探针，对Wistar大鼠肺动脉进行原位杂交。结果：低氧1周组及低氧2周组大鼠大部分肺动脉内皮细胞ET－1mRNA表达呈阳性信号，而对照组大鼠仅极少数阳性信号（P＜0．01）；低氧1周组大鼠部分显示强阳性信号。低氧1周组及低氧2周组大鼠部分肺动脉平滑肌细胞呈现ET-1mRNA表达阳性信号，而对照组大鼠则无阳性信号表达（P＜0．01及0．05）。结论：慢性低氧对大鼠肺动脉ET－1分泌的影响是在基因转录水平进行，且主要细胞定位在肺动脉内皮细胞，此外还包括肺动脉平滑肌细胞。     

异位子宫内膜和在位子宫内膜分泌泌乳素的研究

作者将29例子宫内膜异位症（简称异位症）患者的异位和在位内膜进行离体组织孵育，应用放射免疫方法检测孵育液中泌乳素（PRL）含量；同时应用ABC免疫酶标记法确定异位和在位内膜分泌PRL的部位，结果异位和在位内膜离体组织经0～24h孵育，孵育液中PRL含量均显著增加（P＜0．05）；继续孵育至48h，PRL含量不再增加。但异位内膜分泌PRL的活性低于自身在位内膜。免疫组化PRL检测，异位和在位内膜分别有4和6例呈PRL阳性反应。组织学对照现察，内膜成熟上皮细胞数及前蜕膜细胞数越多者，其相应孵育液中PRL含量越高，免疫组化PRL阳性反应也越强。提示异位内膜PRL分泌特点与其自身在位内膜不完全相同，可能与病理环境有关。     

Gestion des risques et choix de maintenance à l'hôpitalRisks management and maintenance choices at the hospital

Regulations evolve and risks management becomes one of the biomedical engineers' preoccupations. Thus, risks are various, and consequently it is difficult to identify, to manage and to bring them under control. Furthermore, regulations exist for sectors like healthcare technology monitoring, but it is not the same thing for instance for the risks linked to the maintenance. Thus regulation in the sector of maintenance evolves and the decree of the 1^st July law of health safety is going to modify the biomedical environment. The goal of this work is to study the tools and the methods of risks management that have been used for several years in the industrial field and to use them for some biomedical equipment like monitors or IV pumps. These methods adapted to these equipment will allow us to determine some appropriate rules of maintenance.

Is pregnancy the best treatment for hyperprolactinaemia?

This paper reports the changes in prolactin levels after 12 spontaneous and 52 induced pregnancies in 54 women with unambiguous hyperprolactinaemia (median plasma prolactin levels 67.5 ng/ml, range 40-400). Twenty-three of the patients showed radiological evidence of prolactinoma. The pregnancies were induced in 37 patients by bromocriptine, in nine by metergoline, in two by lisuride and in four by other treatments. Of the 64 pregnancies, 16 ended in spontaneous abortion, while 48 went to term. Follow-up was continued for at least 6 months after delivery or until the end of lactation. In a control group of 32 hyperprolactinaemic women (median prolactin 70 ng/ml, range 40-400) not wishing to become pregnant, prolactin changes were similarly registered over a mean period of 15 months without any treatment (range 6-38 months). After pregnancy, a significant downward trend of plasma prolactin was observed in the puerperal women with a 'normalization' rate of 17%. No changes were observed in the 32 controls who did not become pregnant.     

异环磷酰胺为主的联合方案治疗晚期复发鼻咽癌

[目的]观察比较异环磷酰胺(IFO)、顺铂(DDP)、5-氟尿嘧啶(5-Fu)联合方案(IPF方案)与DDP,5-Fu(PF方案)治疗晚期复发鼻咽癌(Ⅲ-Ⅳ期)的近期疗效及毒副反应。[方法]136例均经病理证实为晚期复发鼻咽癌患者,随机分为IPF组69例,PF组67例(对照组)[结果]IPF组和PF组有效率分别为69.56％(48/69)和43.3％(29/67),两组间差异有显著性(X2=8.519,P<0.01)。中位生存期:IPF组16个月(8-34个月),PF组为6.5个月(4-21个月),两组间差异有显著性(X2=22.36,P<0.05)。毒副作用主要为骨髓抑制,Ⅲ-Ⅳ度白细胞下降率IPF组为49.4％,PF组为5.97％,两组差异有显著性(X2=29.54,P<0.01)。Ⅲ-Ⅳ度血小板下降率IPF组为29.18％,PF组为0％(X2=30.29,P<0.01);Ⅲ-Ⅳ度消化道反应两组的发生率分别为15.94％和11.94％(x2=0.234,P>0.01).且以Ⅲ度为主。[结论]以IFO为主的方案联合治疗晚期复发鼻咽癌疗效好,毒副反应能耐受,可作为一线方案。
