目的:探讨尿纤维连接蛋白(fibronectin,Fn)与上尿路移行细胞癌的生物学关系。方法:采用ELISA法检测30例上尿路移行细胞癌、25例其它泌尿系疾病患者及20例正常人尿液Fn含量,并同时测定尿肌酐(Creatin,Cr),计算Fn/Cr比值,比较各组人群尿Fn/Cr比值之间的差异;分析不同肿瘤分期、分级尿Fn/Cr之间的差异;比较其与尿脱落细胞学检测上尿路移行细胞癌的敏感性。结果:上尿路移行细胞癌尿Fn/Cr比值为(46.4±26.5)mg/mol,明显高于正常人(14.7±8.8)mg/mol及其它泌尿系疾病患者(28.2±22.7)mg/mol。以34mg/mol为标准,尿Fn/Cr比值诊断上尿路移行细胞癌的灵敏度和特异度分别为73.3%和77.8%。尿Fn/Cr比值与上尿路肿瘤分期分级有关。尿脱落细胞学检测上尿路移行细胞癌的敏感性为53.3%,采用Fn/Cr检测较脱落细胞学检查敏感性无统计学意义(P>0.05)。结论:尿Fn/Cr可作为上尿路移行细胞癌的诊断指标。其高低与膀胱癌的分期、分级有关,可大致判断浸润度和恶性度,并可用于上尿路移行细胞癌的预后评估。 相似文献

Diagnosis and treatment of pheochromocytoma in urinary bladder 总被引：1，自引：0，他引：1
Objective： To study the diagnosis and treatment ofpheochromocytoma in urinary bladder. Methods： Six cases of bladder pheochromocytoma were studied. Four cases showed hypertension, 3 of which were paroxysmal hypertension during urination. Catecholamine （CA） was increased in a case, and vanillymandelic acid （VMA） was increased in 2 cases. Bladder submucosal mass was detected by B-ultrasound in 5 cases （5/5）, computerized tomography （CT） in 3 cases （3/3）, cystoscopy in 5 cases （5/6）. Four cases took a-receptor blocker for 2 weeks, 1 case took β-receptor blocker to decrease heart rate. All patients were treated with surgical operation including 4 partial cystectomies, 2 excavations. Results： Three cases had manifestations including headache, excessive perspiration and hypertension during cystoscopy. Four cases were confirmed before operation. Two cases showed hypertension during operation. All patients were pathologically diagnosed as pheochromocytoma post- operatively. In five cases followed up, blood pressure returned to normal. No patient had relapse and malignancy. Conclusions： Typical hypertension during urination comprised the main symptoms. We should highly suspect bladder pheochromocytoma if a submucosal mass was discovered with B-ultrasound, CT, ^131I-M1BG （methyliodobenzylguanidine） and cystoscopy. The determination of CA in urine is valuable for qualitative diagnosis. The preoperative management of controlling blood pressure and expansion of the blood volume are very important. Surgical operation is a good method for effective treatment. Postoperative long-time followed up is necessary. 相似文献

Antibacterial and antifungal activities of different parts of Tribulus terrestris L. growing in Iraq
Antimicrobial activity of organic and aqueous extracts from fruits, leaves and roots of Tribulus terrestris L., an Iraqi medicinal plant used as urinary anti-infective in folk medicine, was examined against 11 species of pathogenic and non-pathogenic microorganisms: Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Corynebacterium diphtheriae, Escherichia coli,Proteus vulgaris, Serratia marcescens, Salmonella typhimurium, Klebsiella pneumoniae, Pseudomonas aeruginosa and Candida albicans using microdilution method in 96 multiwell microtiter plates. All the extracts from the different parts of the plant showed antimicrobial activity against most tested microorganisms. The most active extract against both Gram-negative and Gram-positive bacteria was ethanol extract from the fruits with a minimal inhibitory concentration (MIC) value of 0.15 mg/ml against B. subtilis,B. cereus, P. vulgaris and C. diphtheriae. In addition, the same extract from the same plant part demonstrated the strongest antifungal activity against C. albicans with an MIC value of 0.15 mg/ml. 相似文献

Urine has become one of the most attractive biofluids in clinical proteomics,for its procurement is easy and noninvasive and it contains sufficient proteins and peptides. Urinary proteomics has thus rapidly developed and has been extensively applied to biomarker discovery in clinical diseases,especially kidney diseases. In this review,we discuss two important aspects of urinary proteomics in detail,namely,sample preparation and proteomic tech-nologies. In addition,data mining in urinary proteomics is also b... 相似文献

从控制走向协调,以治理代替管理,既是世界高等教育改革的趋势,也是美国公立大学一直努力的方向,而加州大学则是将这种努力践行得较为彻底的一个成功典范.这种努力具体表现为加州大学一方面通过与政府签订协约、引入市场机制、寻求校外群体的支持等形式来弱化政府的管制色彩,另一方面又充分发挥董事会、学术委员会等治理机构的协调作用,为大学自治提供一系列的缓冲与保护. 相似文献
