纤维支气管镜胸膜腔检查对原因不明胸腔积液的诊断价值

为评价纤维支所管镜行胸膜检查在诊断原因不明胸腔积液中的价值，用纤维支气管镜对１０例原因不明的胸腔积液患者进行胸腔检查。结果９例２检查后明确了病因，且无并发症，提示该法对于不明胸腔积液的诊断是一种阳性率高、安全、简便的检查方法。     

原发性胸腰椎管内肿瘤延误诊治原因探讨（附44例报告）

本文报告一组44例原发性椎管内肿瘤初期延误诊治,其中10例为腰椎间盘突出而手术,2例为腰椎管狭窄症手术治疗。原发性椎管内肿瘤与脊柱退变性疾病分属两种不同的疾病范畴。为提高诊断和治疗效果,本文就误诊原因作以下讨论。     

原发性小肠恶性肿瘤的CT诊断

本文回顾性分析３４例经病理证实的原发性小肠恶性肿瘤的ＣＴ表现。病变包括腺癌１６例，平滑肌肉瘤１２例，淋巴瘤６例。ＣＴ扫描能明确肿瘤向腔内和腔外侵犯的程度，清晰显示肿瘤与邻近结构的关系，有无局部及远处转移等，为临床治疗提供帮助。鉴别诊断应包括小肠良性肿瘤、炎性病变和转移性肿瘤等。     

Pharmacist involvement in a thyroid clinic

The patient-care activities of a pharmacist in a thyroid clinic are described. Since 1978 a pharmacist has been an active member of the staff of a thyroid clinic associated with a 500-bed university hospital. More than 1500 patients are referred to the clinic each year. The pharmacist initiates, maintains, or modifies the drug therapy of selected patients with physician-diagnosed thyroid disorders under the guidance of written protocols approved by the chief endocrinologist. Most patients treated by the pharmacist are receiving thyroid-suppression therapy, antithyroid drugs for Graves' disease, or thyroid hormone supplementation after surgery or after radioactive iodine therapy. The pharmacist assesses patients, prescribes medications, orders laboratory tests, charts visits and therapeutic plans, and educates patients about their conditions. Major changes in thyroid status and drug therapy are always discussed with the chief endocrinologist. The pharmacist also participates in educational programs to influence prescribing by physicians, provides drug information, serves as a preceptor to pharmacy students, and is investigating the equivalence of levothyroxine preparations in vivo and in vitro. An audit of patient outcomes showed that the pharmacist is highly effective in her role as a giver of direct patient care. A pharmacist's role in a thyroid clinic can consist of clinical practice, education, preceptorship, and research.     

胃癌D17S261和D17S799位点二核苷酸重复序列不稳定性的意义

目的研究二核苷酸重复序列不稳定性〔ＤＲＳＩ〕在胃癌发生中的作用及其临床意义．方法采用ＰＣＲ方法检测了Ｄ１７Ｓ２６１和Ｄ１７Ｓ７９９位点二核苷酸重复序列不稳定性．结果胃癌总ＤＲＳＩ发生率为３４％（１７／５０），其中高中分化腺癌ＤＲＳＩ阳性率（６６７％，１０／１５）显著高于低分化癌（１９４％，６／３１，Ｐ＜００１）；肠型胃癌ＤＲＳＩ阳性率（５５６％，１０／１８）显著高于胃型胃癌（２０％，６／３０，Ｐ＜００５），ＤＲＳＩ与胃癌部位、大小、浸润、分期、淋巴结转移无显著相关．结论ＤＲＳＩ在胃癌的发生中可能起重要作用．     

Epoxyalkanoyls as novel ACE inhibitors

The epoxyalkanoyl derivatives were designed and synthesized as ACE inhibitors. Coupling of unsaturated carboxylic acids with amino acids and following epoxidation with dimethyldioxirane gave the epoxyalkanoyls with high yield. The inhibitory activity of synthesized compounds on angiotensin converting enzyme was IC₅₀ values of 0.06≈5.5 μM.     

老年人微小病变性肾病综合征的临床特征和长期随访

探讨老年人微小病变性(MC)特发性肾病综合征(PNS)的临床特征及预后。方法 观察成人MC性PNS118例,其中老年患者18例,占15.2％。结果 发现老年患者NS的临床表现与成年组相似;但血尿发病率较低,22％比38％;高血压和肾功能不全的发病率明显增高,38.9％比16％和33.3％比19％(P<0.01)。老年组对激素治疗的敏感性略差;但NS复发率明显减少,11.1％比43％。结论 尽管NS的复发和对激素依赖使治疗有一定困难,但激素、细胞毒性药物和环孢素A对于消除蛋白尿,延缓肾功能不全是有助的。     

腰椎峡部裂的CT诊断

目的：回顾性分析腰椎峡部裂的ＣＴ表现并讨论其诊断与鉴别诊断，材料与方法，２３例患先行腰椎侧位扫描定位图像，采用与椎间盘平行的角度，自病变脊椎的上一椎体下缘边续发描至于下椎体上缘，层厚４或５ｍｍ必要时在峡部行２ｍｍ，层厚扫描，结果；２３例中，累及双侧２１例，单侧２例，发生在Ｌ５１６例，Ｌ４７例，ＣＴ表现为同一脊椎关节突间的低密度裂隙，出瑞椎弓根下缘平面，走行不规则，裂隙可宽可窄，表面不光滑。
