因症就诊检出早期大肠癌的临床及病理学特征

目的探讨在就诊的肛肠病人中如何提高早期大肠癌的检出率。方法在１１家医院推广对肛肠病人的四项检查程序——直肠指检，乙结镜检查，大便隐血试验，和Ｘ线气钡灌肠造影。结果在４８２１例有肛肠症状的病人中，检出大肠癌１８８例，检出率为３．９％，其中１８０例有术后病理诊断。４７／１８０例（２６．１％）属早期癌（ＤｕｋｅｓｓｔａｇｅＡ）。４１／４７例由上述四项检查作出初步诊断。初发症状为：（１）便血（２６例，持续１５．２±９．４周后就诊，肿瘤平均直径２．５８ｃｍ）；（２）大便习惯改变（９例，３３．４±１９．７周，３．３９ｃｍ）；（３）腹痛腹块（１０例，１９．２±１１．２周，５．０ｃｍ）；（４）贫血（２例，１７．２±９．９周，４．７５ｃｍ）。８／１２例的Ａ０和Ａ１期病例属便血组，并多位于直肠。４１／４７例以高、中分化腺癌为主，其中１５例伴有腺瘤癌变。术前曾作活检的２７例中，１２例未检出癌变细胞。结论四项检查对检出早期大肠癌是有效的，便血是提示早期癌最有价值的症状，加强大肠癌防治宣教，采用瘤灶多点或全瘤活检技术，高度重视大肠腺瘤和不典型增生等癌前病变，将有助于提高早期大肠癌的检出率

Pneumatosis cystoides intestinii

Zusammenfassung Die Pneumatosis cystoides intestinii (PCI), das Auftreten submuköser oder subseröser, gasgefüllter Zysten in der Wand des Gastrointestinaltrakts, tritt als seltene Erkrankung ohne eindeutige Geschlechtspräferenz vorwiegend in der 3. bis 5. Lebensdekade auf. Atiopathogenetisch werden unterschiedliche Faktoren diskutiert, am wahrscheinlichsten ist eine bakterielle Ursache (Clostridium perfringens) in Verbindung mit einer minimalen Unterbrechung der Mukosaintegrität. Eine pathognomonische Symptomatik gibt es nicht, das klinische Bild reicht von asymptomatischen Zufallsbefunden bis zur Hämatochezie. Die Diagnose wird durch den Nachweis der Gaseinschlüsse mittels Abdomenübersichtsaufnahme und Kolonkontrasteinlauf gestellt. Als Behandlungsmethoden für symptomatische Patienten stehen Sauerstofftherapie, Antibiotikagabe (Metronidazol) und in schweren Fällen die Resektion des betroffenen Darmabschnitts zur Verfügung.

Pneumatosis cystoides intestinalis (PCI), a condition involving submucosal or subserosal gas-containing cysts of the wall of the gastrointestinal tract, is a rare entity. It is mostly diagnosed between the third and fifth decades of life without a clear sexual predominance. Different aetiopathogenetic factors are under discussion, the most probable being a bacteriologic cause (Clostridium perfringens) in combination with minimal leaks in mucosal barrier. There are no pathognomonic symptoms; the clinical picture ranges from incidental findings to haematochezia. Diagnosis is based on plain abdominal film and X-ray following barium enema. Methods of treatment in symptomatic cases are oxygen and antibiotic (metronidazole) therapies and, in severe cases, resection of the diseased part of the intestine.

     

Quality of life assessment and HIV infection: A review

In the last few years, survival of patients infected with human immunodeficiency virus (HIV) has been improved because of a decreased incidence of some opportunistic complications attributable to prophylactic treatments and antiretroviral drugs. The impact of these agents should also be reflected in the quality of life (QoL) of patients. We have reviewed this topic with an emphasis on different types of measurements such as Q-TWIST, MOS and the Spitzer score which seem to be most appropriate for this patient population. We do not think that a special type of assessment should be designed for HIV-infected persons. It would be less time-consuming to improve already existing validated scores focusing on HIV infection. QoL in intravenous drug users with HIV should be evaluated more often.     

环丙沙星与氧氟沙星注射液治疗细菌性感染的疗效观察

以乳酸环丙沙星（ＣＰＬＸ）注射液和氧氟沙星（ＯＦＬＸ）注射液随机分组治疗各种细菌性感染４０例及４２例，并以注射用头孢噻肟钠（ＣＴＸ）治疗４９例作对照。三组平均年龄、体重、疗程及病情程度相比无显著性差异，具可比性。病种分布以消化道感染最多，共８１例，占总数的６１．８％。三组１３１例病人细菌阳性率为９４．７％。一疗程ＣＰＬＸ组、ＯＦＬＸ组、ＣＴＸ组治愈率分别为８７．２％、８３．３％、７１．４％，有效率     

Clinical Evaluation of a New Type of Centrifugal Pump

Abstract: The major problems with existing centrifugal pumps are leakage, mechanical trauma, and thrombus formation. In consideration of these problems, a new compact centrifugal pump system was developed. The purpose of this study was to evaluate the new centrifugal pump system clinically. Ten patients underwent open heart surgery with a centrifugal pump or a roller pump. During surgery, hemodynamic and hematological data were obtained. A pulsatile assist device in the pump circuit was used in patients with severe heart disease. There was neither operative death nor hospital mortality, and there was no difference with regard to hemodynamic data between the two groups. The centrifugal pump group, however, had significantly lower hemolysis, especially during prolonged cardiopulmonary bypass. This centrifugal pump could also create sufficient pulsatile flow with a pulsatile assist device. Postoperative macroscopic and microscopic findings demonstrated the smooth surface of the pump without thrombus formation. This centrifugal pump system might be useful for prolonged cardiopulmonary bypass.     

通瘀注射液盆腔给药法治疗外在型子宫内膜异位症的临床研究

目的　运用通瘀注射液在非直视下经输卵管盆腔给药对子宫内膜异位症 (EEMs)的治疗作用 ,探讨活血化瘀法对EEMs的作用机理及此给药法的优势。方法　将临床治疗的EEMs患者 60例随机分为治疗组 (通瘀注射液组 )和对照组 (丹那唑组 ) ,疗程各为 3个月。用药前后测定下列指标 :临床症状与体征、内分泌激素、血液流变学、癌抗原 12 5 (CA12 5)和子宫内膜抗体 (EMAb)的阳性率变化。结果　治疗组的临床症状与体征、血液粘滞度和红细胞压积、CA12 5和EMAb的阳性率均降低 ,卵泡刺激素 (FSH)、黄体生成素 (LH)、雌二醇 (E2 )和孕激素 (P)的含量均受到调节 ,与对照组相比 ,差异有显著性。而治疗组对内分泌的调节能力弱于对照组 ,但作用柔和、均衡。结论　通瘀注射液对EEMs的作用是通过清除月经时异位内膜的瘀血、水肿、改善微循环及组织供氧、调节免疫功能和内分泌紊乱而实现的 ,与丹那唑相比其副作用小、并以治本为主。盆腔给药法则可使药物直达病灶 ,见效快     

91例甲状腺疾病临床病理诊断分析

在临床病理手术切除中甲状腺疾病很常见，其疾病的良恶性鉴别和具体类型诊断有一定难度。因甲状腺疾病的病因复杂，有多病变并存现象，且密切相关、相互影响，如何合理准确地进行病理诊断是指导临床治疗和随诊的重要依据。现将我科2002年1月至2004年12月91例甲状腺病理活检材料进行回顾性分析，以进一步提高甲状腺疾病诊断和鉴别诊断水平。     

右室梗死临床诊疗新进展

右室梗死过去只能在尸检时确诊。20世纪70年代以来,随着医师诊断水平和检测设备的不断进步,临床上已能在患者生病确诊右室梗死[1],现对国内有关资料综述如下,仅供同道参考。1右心室栓塞发病及研究进展右心室心肌梗死是指累及右心室壁的心肌梗死。临床上相对少见。尸检病例中,单独右心室梗死不到3%,左心室心肌梗死同时延伸至右心室者占43%[1]。按其梗死发生部位分为:右心室游离下壁;右心室游离前壁;右心室游离下壁、前壁及右心室乳头肌。受累部位取决于受损血管的来源,右心室前壁和前乳头肌由左前支和圆锥支供血,前者分支较多,一般不会全部阻…
