原发性淀粉样变性的临床病理及电镜观察

淀粉样变性是指淀粉样蛋白在皮肤，粘膜或内脏器官的细胞外沉积引起的一种少见疾病。口腔粘膜中舌粘膜是本病的好发部位。本组４例典型地发生于口腔颌面部的原发性淀粉样变性病例，３例病变部位为舌，１例为皮肤和口腔粘膜同时受累，临床提示有必要进行全身系统检查及追踪随访。并就基临床表现，常规病理，组织化学及电镜进行研究，同时讨论了淀粉样蛋白的光镜，电镜特点，组织学类型生化组成及来源。     

氟西汀与阿米替林治疗105例抑郁障碍病人的双盲对照试验

目的：评价国产氟西汀的抗抑郁作用及安全性。方法：采用随机、双盲对照、多中心研究，分为国产氟西汀组５７例（男性２２例，女性３５例；年龄４０±ｓ１３ａ），口服氟西汀２０ｍｇ，ｑｄ，阿米替林５７例（男性２７例，女性３０例；年龄４０±１４ａ），口服阿米替林７５ｍｇ，ｂｉｄ，疗程６ｗｋ。结果：氟西汀治疗抑郁障碍的疗效与阿米替林相当，总有效率分别为８５％及９２％（Ｐ＞０．０５）；氟西汀组的主要副作用有口干、便秘、恶心、心动过速等，但较之阿米替林程度轻且发生率低。结论：氟西汀的抗抑郁作用与阿米替林相当，副作用少，服用方便。     

一次手术法对自制两段式种植体种植效果的实验研究

本实验用自制纯钛两段式种植体,以一次手术法植入到狗的下颌前磨牙区,观察5个月,结果表明,观察期间内牙龈无炎症,种植体稳固,X线片显示种植体周围无透射区,镜下可见种植体表面与牙龈之间形成上皮附着样结构,与骨组织之间大多呈骨性愈合。提示了两段式种植体有两种设计和手术方式可供选择。骨内部分在开放的环境中也可达到骨性愈合。     

金属换热器传热过程的数学模型及应用

应用蒙特卡洛法仿真辐射式金属换热器内的辐射传热过程，建立了换热器综合传热的数学模型，利用概率论原理，把辐射能迁移过程仿真为一定累积概率分面下的随机过程，该模型能较好地反映换热器内传热过程的真实情况，可以计算出换热器内烟气、筒壁、空气的温度和壁面热流分布，以及研究烟气进口温度、换热器筒径和狭逢宽度对换热效果的影响。     

Invasive techniques for the diagnosis of respiratory infectious diseases

Conclusion Reviewing the history of diagnostic procedures of causative organisms of respiratory infections, invasive techniques such as the protected specimen catheter (PSB) and bronchoalveolar lavage (BAL) have become the preferred choices because they have many advantages. These methods cause the patient relatively little discomfort, and permit an early diagnosis since they can easily be performed at the bedside and the causative organism from the disease site is obtained in cultures. These procedures can be used not only in patients with community-acquired lung infections, but also in immunocompromised hosts, including those with blood diseases or following renal transplantation, in patients in intensive care units and in mechanically-ventilated patients so that the cause can be accurately determined and chemotherapy started quickly, resulting in better therapeutic efficacy. Although these invasive procedures are advantageous for the diagnosis of respiratory infections, they also present various problems which remain to be addressed including minimizing contamination and setting diagnostic threshold values. However, the importance of accurately determining the causative organism in respiratory infections should be recognized as the most important factor, and these methods have shown to date to provide the most accurate information to aid in the timely treatment of respiratory infections in a wide variety of patients.
