卵巢浆液性囊腺癌的CT诊断（附三例报告）

作者报告了三例经手术病理证实的卵巢浆液性囊腺癌的临床及CT表现，分析了其中2例经化疗后转移的CT特点，CT主要表现为：（1）盆腔内囊实性肿块，部分肿块内有钙化；（2）肉膜饼状转移。（3）脏器的浆膜及系膜播散；（4）钙化性转移，CT对本病的诊断与分期均优于临床检查。     

急性白血病非系限性分化抗原的动态研究

为探讨仅表达非系限性分化抗原的急性白血病的细胞起源，采用单克隆抗体免疫酶标和聚合酶链反应技术分析了１２例初诊时仅表达非系限性分化抗原的急性白血病化疗后免疫表型及免疫球蛋白重链（ＩｇＨ）和Ｔ细胞受体（ＴＣＲ）γ基因重排的变化。结果表明：初诊时仅表达ＣＤ３８抗原的５例急性白血病，化疗后３例出现Ｔ细胞相关抗原表达，并伴ＴＣＲγ基因重排；５例初诊时仅表达ＨＬＡ－ＤＲ或ＣＤ９的急性白血病，化疗后４例出现Ｂ细胞相关抗原表达，均伴有ＩｇＨ基因重排；２例无任何抗原表达者，化疗后１例表达Ｂ细胞相关抗原，另１例表达骨髓细胞相关抗原。提示免疫标志的动态研究，有助于初诊时免疫学无法分类急性白血病细胞起源的确定。     

硬脑膜动脉海绵窦瘘的眼眶CT表现,DSA检查及栓塞治疗

笔者分析了５例硬脑膜动脉海绵窦瘘伴突眼，结膜充血的病例，全部经ＣＴ及ＤＳＡ检查，同时进行了栓塞治疗，经随访７－９个月未见复发，主要ＣＴ表现为：（１）眼球突出，结膜充血；（２）眼上静脉扩张；（３）海绵窦增大；（４）眼外肌增厚：（５）眶尖软组织肿胀。并讨论了诊断鉴别诊断，ＤＳＡ检查及有关治疗问题。     

完全性大动脉转位的外科治疗

对３３例完全性大动脉转位施行了手术治疗，其中全腔静脉肺动脉连接３例、改良Ｆｏｎｔａｎ手术２例、Ｍｕｓｔａｒｄ及大动脉调转术各１例，Ｒａｓｔｅｌｉ手术２６例，包括１５例心内隧道和心外管道，１１例心内、外双管道。这２６例心外管道中，除４例采用同种主动脉管道外，其余为经处理的猪肺动脉人工管道。全组手术死亡１０例，晚期死亡１例。结论：完全性大动脉转位病理解剖变异性大，应按不同类型的病理解剖特征选择手术方法     

Basic fibroblast growth factor enhances bone-graft incorporation: Dose and time dependence in rats

In a previous study, we found that basic fibroblast growth factor could stimulate bone-graft incorporation. In the present study, the effects of different doses and implantation times were further studied, using the bone conduction chamber, in rats. Inside the chamber, the graft is isolated from the surrounding tissues except at one end, where small openings embedded in host bone allow ingrowth of tissue. The distance that new tissues had reached from the openings into the graft was measured on histological slides. Bone grafts were obtained from the proximal tibiae of donor rats, frozen at ?70°C, and lipid-extracted. Before implantation, they were soaked overnight in a hyaluronate gel with or without basic fibroblast growth factor and then were fitted into the chambers, which were implanted in the proximal tibiae of recipient rats. In a doseresponse experiment, grafts containing 0.3, 8, 40, 200, or 1,000 ng of basic fibroblast growth factor were compared with grafts treated with carrier gel only, after an implantation time of 6 weeks. Fibrous tissue always penetrated the grafts further than the ingrown bone; the distance that it reached from the ingrowth openings (total ingrowth distance) was increased by all of the doses except 0.3 ng per implant. The distance of bone ingrowth was increased by 8, 40, and 200 ng. The increased total ingrowth with 1,000 ng was due to an increased amount of fibrous tissue ahead of the bone, whereas with the lower doses the increase was due to more bone. Thus, the dose had an effect on the type of ingrown tissue found in the graft. In a time-effect study, grafts treated with 40 ng of basic fibroblast growth factor had a higher uptake of [^99mTc]MDP at 2 and 4 weeks and an increased bone ingrowth distance at 10 weeks. The radioactivity from [¹²⁵I]basic fibroblast growth factor declined with a half-life of 17 hours. The results suggest that basic fibroblast growth factor may be beneficial for the incorporation of contained bone grafts; studies using more clinically relevant models are required.     

胰岛素对数种缩血管物质作用的影响

目的 观察胰岛素对去甲肾上腺素、内皮素-１、氯化钾（ＫＣＩ）、血管紧张素Ⅱ和５－羟色胺缩血管作用的影响。方法 用ＳＤ大鼠的离体动脉血管观察缩血管物质的作用。结果 在含有１ｍＵ／ｍｌ胰岛素环境中，胰岛素对数种缩血管作用机制不同的物质有程度不同的血管增敏作用。对去甲肾上腺素、内皮素－１和ＫＣＩ有明显的增敏效果；对血管紧张素Ⅱ有增敏趋势，但无显著性差异；对5－羟色胺无增敏效应。结论 胰岛素在高血压的发病过程中可能起重要作用。     

复方丹参注射液与维生素B6、C注射液配伍稳定性试验

本文观察了复方丹参注射液与维生素B6、维生素C注射液的配伍稳定性，结果表明复方丹参注射液与维生素B6注射液可以在4h内配伍使用，而不能与维生素C配伍。     

男性不育患者的心理健康状况及相关因素探讨

目的　探讨男性不育患者的精神状况及与之相关的因素。方法　对 90例男性不育患者和 93例已婚有子女的健康男性进行症状自评量表和一般情况问卷调查。结果　男性不育患者的心理刺激重 ,症状多。不育患者的精神压力与职业、文化程度、每周性生活次数密切相关。农民、文化层次较低及性生活次数多的男性不育患者精神负担重 ,主要表现为人际关系敏感、抑郁、焦虑或偏执等症状。结论　建议在对不育男性尤其是农民不育患者进行不育治疗的同时给予心理健康服务和生育知识指导 ,以缓解患者的精神压力。
