目的:探讨骨调素(OPN)和单核细胞趋化蛋白(MCP-1)在大鼠梗阻性模型中的表达及其在肾脏纤维化发病机制中的作用.方法:采用-单侧输尿管结扎制造梗阻性肾病模型,分别于造模后7 d、14 d取肾组织,应用HE染色观察肾脏病理改变,免疫组化方法检测肾组织畔OPN和MCP-1蛋白的表达,应用逆转录-聚合酶链式反应(RT-PCR)法观察肾组织中OPN mRNA和MCP-1 mRNA的变化.结果:OPN、MCP-1表达主要位于肾小管上皮细胞,随着梗阻时间的延长,肾组织中OPN、MCP-1蛋白和mRNA表达明显增加.结论:OPN、MCP-1蛋白和mRNA在梗阻性肾病大鼠肾组织表达明显增加介导炎症过程,参与肾间质纤维化.  相似文献

输尿管梗阻致肾包膜下积液8例报告   总被引:3,自引:0,他引:3  
目的:探讨输尿管梗阻致肾包膜下积液的原因与处理办法。方法:报告8例此种患者的临床资料。8例患者均经影像学检查确诊;输尿管结石所致者5例,外来肿瘤压迫输尿管、良性疾病手术后输尿管受压和放疗所致输尿管梗阻者各1例。针对梗阻原因分别行输尿管逆行插管、碎石、手术探查及肾包膜下穿剌等治疗。结果:8例患者输尿管梗阻解除后肾包被膜下积液均消失,肾功能恢复正常。结论:肾包膜下积液大多由泌尿系结石致梗阻而引起,也可由输尿管附近病变压迫输尿管致管腔梗阻所致。影像学检查对本病的诊断具有重要作用,解除梗阻后肾功能常恢复良好。  相似文献

目的:探讨良恶性肝外胆管梗阻病变的CT表现及其诊断意义。方法:回顾经手术病理证实的肝外胆管梗阻病变76例(良性34例,恶性42例)。结果:肝内胆管呈枯枝状轻中度扩张,肝内外胆管不一致扩张(内轻外重),肝外胆管远段梗阻,梗阻部胆管呈削尖状狭窄,肝外胆管壁呈弥漫环形增厚,对良性梗阻的诊断有重要意义。肝内胆管呈软藤状重度扩张,肝外胆管中段梗阻,梗阻部胆管呈伴或不伴肿块的截断型或突然狭窄型,肝外胆管壁局限不规则增厚,高度揭示恶性梗阻。结论:良恶性肝外胆管梗阻病变均有特征性CT表现,通过分析胆管形态和临床资料基本能判断梗阻的性质。  相似文献

During a period of twenty years [1969-1988] the author has observed 614 cases of congenital malformations and noninflammatory diseases of the larynx in infants and young children, Budapest. He summarizes the most characteristic symptoms of laryngeal pathology in infants, and discusses the diagnostic possibilities. Among the latter, spectrographic analyses complemented by auditory evaluation of pathological cry and different breathing noises play an important role. Based on his investigation author differentiates 20 kinds of pathological crying sounds and 4 basic forms of stridor. He describes the acoustic attributes of different pathological sound phenomena and summarizes characteristic voice changes.  相似文献

上腔静脉梗阻外科治疗(附5例报告)   总被引:1,自引:0,他引:1  
本文通过应用大隐静脉、人造血管与经戊二醛处理后的新生儿脐带静脉,分别为5例上腔静脉梗阻进行6例次转流术或上腔静脉重建术,认为脐带静脉具有取材容易,处理简单,血管口径一致,无静脉瓣,缝合较易等优点;大隐静脉适用于不开胸者,为减轻症状治疗首选材料;人造血管不宜代上腔静脉。上腔静脉梗阻手术治疗指征是,当梗阻发生在奇静脉或其以上,侧枝循环少,左右无名静脉通畅,病人有不能耐受的脑部和呼吸道症状,估计能够耐受开胸手术。  相似文献

BACKGROUND: The role of atopy in the evolution to chronic obstructive disease remains controversial. AIM: We aimed to assess the association between individual sensitization to common allergens and lung function. METHOD: We analysed data from 12,687 subjects aged 20 to 44 years, from 34 centres in 15 countries participating in the European Community Respiratory Health Survey (ECRHS). Participants performed a blood test, lung function test, methacholine challenge, and answered an administered questionnaire. The relationships between specific IgE, FEV1 and FEV1/FVC ratio were assessed for each study centre stratified by sex, followed by random effects meta-analysis. RESULTS: Asthmatics sensitized to house dust mite had a lower FEV1 (-119 mL in women and -112 mL in men) and FEV1/FVC ratio (-1.95%, and -2.48%) than asthmatics without sensitization. Asthmatics sensitized to cat had a lower FEV1 (statistically significant for women only) and a lower FEV1/FVC ratio. Asthmatic women sensitized to grass had a lower FEV1 and a lower ratio, and those sensitized to Cladosporium had a lower FEV1. A weak association was found with sensitization to cat and to Cladosporium among non-asthmatic women, which disappeared after adjusting for BHR. CONCLUSION: We conclude that atopy was related to a lower lung function, which was only apparent among asthmatics. This relationship was explained by specific sensitization to cat and to house dust mite, the latter being homogeneous across areas.  相似文献

One hundred and one children over 1 year of age have had surgery for pelviureteric obstruction over an 11 year period. The common clinical features were abdominal pain, urinary infection or haematuria, but number presented as an incidental finding. Less commonly, the patients presented with an abdominal mass or with hypertension. The diagnosis was usually made on intravenous pyelography (IVP) but in the latter part of the series, renal nuclide scan (RNS) and ultrasonography (US) were preferred. Ninety–three patients had unilateral pyeloplasty, three had bilateral pyeloplasty and five had nephrectomy or heminephrectomy. Whereas initially nephrostomy drainage was used in the majority of patients after pyeloplasty, trend away from nephrostomy evolved in the latter part of the series. With experience, the incidence of postoperative complications was also reduced and there was reduction in the period of hospitalization. Clinical results were consistently satisfactory. Postoperative assessment after pyeloplasty was made by IVP and/or RNS and also US. A review of these investigations showed that RNS provided more factual information of the result when compared with the IVP.  相似文献

A 73-year-old male with a history of diabetes mellitus was admitted to our hospital for acute renal failure. An ultrasonogram revealed bilateral hydronephrosis, which worsened despite insertion of a bladder catheter. Nephrostomy catheters were positioned bilaterally, and Candida albicans was found in the urine culture. The patient was successfully treated with intermittent direct irrigation and i.v. antifungal agent therapy. Since 1977, approximately 50 cases of fungus balls or fungal bezoars in the urinary tract have been reported, but the majority of these cases have been characterized by unilateral ureteral or bladder involvement. Herein, we report a case of acute renal failure as a result of bilateral ureteral obstruction by Candida albicans fungus balls.  相似文献
