垂体腺瘤的CT诊断(附60例分析)

分析了60例垂体腺瘤的CT表现。1例垂体微腺瘤缺乏特异性征象,59例大腺瘤大多数表现典型,诊断依据为肿瘤位置和蝶鞍改变。垂体腺瘤的形态学表现无特异性。应加强对垂体瘤卒中和侵袭征象的认识。对成人鞍区肿瘤的鉴别诊断进行了简短讨论。

The use of quinacrine (Atabrine) in rheumatic diseases: A reexamination

Atabrine has been available for nearly 60 years. It has a variety of actions and has been administered to millions of individuals. Its antirheumatic properties have been well documented but have not been exploited optimally for a variety of reasons. The drug is generally quite safe and could be used in low doses in lupus and rheumatoid arthritis patients as a steroid-sparing agent or synergistically with hydroxychloroquine. Its bothersome side effects should not deter the clinician from using it, because they are easy to deal with or prevent (Table 5). Future studies should attempt to better characterize the immunosuppressive actions of this powerful drug, particularly in the treatment of lupus erythematosus and rheumatoid arthritis. Studies of the role of combination or single-agent antimalarial therapy in combination with other "remittive" drugs could be of great potential benefit.     

改变在体兔左心室后负荷对其电生理参数的影响

目的：探讨改变在体兔左心室后负荷对室性心律失常发生情况及左心室电生理参数的影响。方法：改变左心室后负荷，观察室性心律失常发生情况，并测定左心室舒张阈值（ＶＤＴ），相对不应期（ＲＲＰ），有效不应期（ＥＲＰ）及其不应期离散和心室纤颤阈（ＶＦＴ）。结果：逐级增加左心室后负荷（ＡＢ级）可使左室空间ＲＲＰ，ＥＲＰ离散增加（Ｂ级，Ｐ＜００５），ＶＦＴ降低（Ｂ级，Ｐ＜００１）；各实验动物均出现室性心律失常（Ｂ级）；而逐级减小左室后负荷（ＣＤ级），心室电生理参数无变化（Ｐ＞００５），各实验动物亦无室性心律失常发生。结论：增加左心室后负荷诱发室性心律失常，与左室空间不应期离散增加有关。     

The Turner syndrome research registry: Creating equipoise between investigators and participants

To address knowledge gaps about Turner syndrome (TS) associated disease mechanisms, the Turner Syndrome Society of the United States created the Turner Syndrome Research Registry (TSRR), a patient‐powered registry for girls and women with TS. More than 600 participants, parents or guardians completed a 33‐item foundational survey that included questions about demographics, medical conditions, psychological conditions, sexuality, hormonal therapy, patient and provider knowledge about TS, and patient satisfaction. The TSRR platform is engineered to allow individuals living with rare conditions and investigators to work side‐by‐side. The purpose of this article is to introduce the concept, architecture, and currently available content of the TSRR, in anticipation of inviting proposals to utilize registry resources.     

企业员工应激源的因素结构研究

目的 :该研究旨在确立企业员工应激源的因素结构。方法 :经过对 394 6名被试的探索性因素分析 ,提出企业员工应激源的 9因素结构。结果 :因素分别命名为职业发展、住房问题、工作特征、社会环境、人际关系、经济收入、子女问题、组织气氛和夫妻关系。结论 :企业员工应激源的 9因素结构获得了验证性因素分析的支持。     

卵巢宫内膜样腺癌的病理组织学及组织化学分析

本文通过对２４肺卵巢宫内膜样腺癌的巨检，镜及组织化学染色等结果分析，提出按该瘤所含组织成分，将其分为单纯型及混合型两大类。单纯型中分化程度不同又再分成Ⅰ，Ⅱ，ⅢⅣ级。混合型中根据所含成分又再分为腺棘癌，腺鳞癌，透明细胞腺癌型，含粘液腺癌型及含浆液腺癌型。讨论了该瘤的临床表现，发病率，组织来源，病理特征，诊断步骤及各类型与预后之间的关系。     

胆总管的矢状断层解剖研究

在３０套成人腹部连续矢状断层标本上，胆总管与下腔静脉主要出现于Ｒ２－Ｒ３断层；胆总管胰腺段与胰头的关系有部分包埋，完全包埋及胰腺后型；十二指肠大乳头集中出现于Ｒ３断层；胆总管的行程有４种形式。文内还探讨了矢状断层里胆总管各段的毗邻及识别标志。
