采用一式三份数码对号入座法管理病案号

采用"对号入座法"管理病案号,先把姓名索引卡、病案封面、病案号索引簿预先印上号码.待病人入院,取出相应一式三份号码,做好各种索引.结果,派出的病案号被取出,乘下空白的是未使用.如果旧病友再次入院;就要在病案的姓名索引中或电脑中查找旧号,这样有效地控制重号、漏号.     

隆突性皮纤维肉瘤23例临床分析

本文报告了我科1978～1990年间收治的降突性皮纤维肉瘤23例,均经组织学证实.治疗以手术切除为主,术后局部复发率为65.2%.无一例发生转移.切除不彻底是复发的主要原因.作者指出广泛切除是防止复发的主要措施,手术前后的放疗有可能减少复发.     

中国中原地区33555名妇女妇科疾病发生情况与五种因素关系的调查报告

自１９９２年３月至１９９４年５月，对中原地区４个省２０多个县（市）近２００个单位３３５５５名２０～７５岁的已婚妇女，进行妇科疾病发生情况与年龄、职业、文化、月经、孕产等五种因素关系的调查分析。在３３５５５名妇女中，患病者２２３７０人，总患病率为６６．６７％，查出妇科疾病４２种，计７６９７４例次。结果证明：以２５～３５岁年龄组发病率最高，其中以内生殖器炎症为主；职业以经商者发病率高，特别是性病患者高于其他职业者二倍以上；文化程度以小学、初中者发病率高，尤其宫颈炎更明显；月经情况：随着经前期紧张综合征的加重，更年期综合征发病率增高；孕产次数越多，患病率越高。本次调查未发现宫颈癌，进一步证明我国对妇女保健工作的关心和重视。     

Antithrombotic effect of beta,beta''-monochloromethylene diadenosine 5'',5"''-P1,P4-tetraphosphate.

The feasibility of using beta,beta'-monochloromethylene diadenosine 5',5"'-P1,P4-tetraphosphate (AppCHCl-ppA) as an antithrombotic agent was studied in a rabbit intracarotid cannula thrombosis model previously shown to be sensitive to antiplatelet agents. This analogue, having a P-C-P bridge in place of a P-O-P internucleoside linkage, has been found resistant to phosphodiesterase activity. Rabbits were infused with the dinucleotide at a dose of 50 mg per kg over a 2-hr period, at a controlled rate by pump. A 1-cm length of polyethylene cannula (1 mm i.d.) was tied into the carotid artery. Animals were stable under general anesthesia during the entire period of the experiment. In the control group, 16 of 20 animals formed clots, an incidence of 80%, whereas in the test animals, 6 of the 20 formed clots (30% incidence, P < 0.05). After preincubation of whole blood with 50 microM AppCHClppA at 37 degrees C for up to 3 hr, a consistent suppression of ADP-induced platelet aggregation was observed. The present study suggests that AppCHClppA may be useful as an antithrombotic agent in certain clinical situations, such as hemodialysis, arteriovenous shunts, and introduction of artificial heart valves. It may also possibly prevent extension of recent clots. The toxicity and metabolism of AppCHClppA have, however, yet to be explored.     

磁刺激用平面线圈结构的优化研究

文中建立了采用任意形状平面线圈磁刺激仪的RLC模型，给出了模型参数的计算方法。为了优化线圈，将磁刺激仪线圈的性能指标分为反映线圈输出性能的峰值磁能和反映线圈结构的几何变量。在磁刺激激活函数达到阈值条件下，调整平面螺旋线圈的结构并计算出依赖于线圈结构参数的输出性能值，从而，寻找最优的线圈几何参数。优化结果表明：线圈外半径是关键因素，给定阈值条件，选择合适的线圈外半径，可以大大降低线圈峰值磁能；另外，现在使用的圆环线圈并非最优，D形线圈优于圆环线圈。     

高千伏摄影附加滤过与皮肤入射剂量相对关系的实验研究

目的：通过测量不同滤过条件下，体模入射剂量随滤过条件的变化确定高千伏X线摄影时的最佳附加滤过。材料与方法：利用X线剂量仪测量不同Al滤过时对应体模表面剂量的变化。结果与结论：通过适当增加附加滤过可以合理降低被检者皮肤剂量，120kV摄影时，附加滤过2.5mmAl是恰当的。     

Transforming growth factor J3 type II receptor (TGFpRII) mutation in gastric lymphoma without mutator phenotype

A new mutation in the serine-threonine klnase domain of the transforming growth factor β type II receptor (TGFpRII) was found in a case of diffuse, B cell non-Hodgkin's lymphoma of the stomach. A mfssense mutation (ACA to GCA, Thr to Ala) was detected In exon 5, and a wild type allele was also present. This Is the first naturally occurring mutation in the klnase domain of this gene identified in human primary lymphoma. The replication error at three loci was negative, and the poly A tract of exon 3, which is frequently a target of mismatch repair genes, was intact. Malignant lymphoma of B cell origin in the stomach Is an addition to an expanding catalogue of tumors with TGFβRII alterations, and the biological sequelae of the change in the functional domain and the clinical characteristics of the patient in this study are intriguing.     

大Y携带者不良孕产史与胚胎非整倍体率增高的关系

目的探讨1例有不良孕产史的大Y携带者的胚胎异常情况。方法1对有2次自然流产史的夫妇,男方染色体核型为46,XY,Yqh ,常规超促排卵和卵母细胞胞浆内单精子注射,受精后第3天和第4天进行胚胎活检,获取分裂球,采用18,X,Y三色着丝粒探针进行荧光原位杂交分析(FISH),第5天移植正常胚胎。异常胚胎及废弃胚胎所有分裂球第6天再次FISH确定胚胎核型。结果患者获卵19个,对其中13个M2期卵母细胞进行ICSI,12个受精,分裂11胚。10个胚胎获得明确诊断,其中4个正常胚胎,6个异常胚胎,异常发生率达60%。5个为女胚,其中1个正常核型,4个异常胚胎中2个为无序分裂,2个为嵌合体;5个为男胚,3个正常,2个异常胚胎中1个为无序分裂,1个为嵌合体。对染色体正常的1个女胚进行宫腔内移植,未获得妊娠。结论该例大Y患者胚胎非整倍体发生率增高可能是导致其不良孕产史的原因。
