作者报告经病理诊断消化道恶性肿瘤患者30例及手术切除肿瘤患者15例的血浆胃动素水平,并以健康成人31例作为对照。消化道恶性肿瘤的胃动素水平373.4±123.7ng/L,显著高于正常对照组(162.3±52.3ng/L,P<0.001),而消化道恶性肿瘤患者术前及术后胃动素水平无显著差异。消化道恶性肿瘤患者胃动素水平增高的原因可能是肿瘤刺激神经所致。胃癌和结肠癌细胞可产生胃泌素样物质,它可刺激胃动素的释放。 相似文献

报告手术治疗腰椎间盘突出症合并退行性腰椎管狭窄症104例。术后随访90例,随诊时6个月~6年。优良率86.5%,无腰椎不稳和腰椎滑脱等并发症。为获得优良效果,作者强调在处理椎间盘突出的同时必须彻底解除侧隐窝及神经根管,黄韧带肥厚对神经根的压迫,才能彻底根除症状 相似文献

In situ saphenous vein grafts are being used with increasing frequency for bypass procedures involving the femoral and popliteal arteries. Complications of these procedures include anastomotic stenoses and persistent arteriovenous fistulae that may result in failure of the graft. Balloon angioplasty and embolotherapy with detachable balloons were employed successfully in three or four recent cases of patients with complications from in situ grafts. Tailored angiography is essential for evaluating in situ grafts, and interventional techniques are extremely useful for managing complications. 相似文献

Polycystic kidney disease is an autosomal dominant disease that may be associated with cystic disease of the liver. In women, the cysts may develop early and be more troublesome than in men. Cystadenocarcinoma of the pancreas is uncommon, comprising 1% of primary pancreatic malignancies. This case report is the first to describe a familial association between polycystic kidney disease and cystadenocarcinoma of the pancreas and liver in the English medical literature. A patient with autosomal dominant polycystic kidney disease (ADPKD) and multiple hepatic cysts developed cystadenocarcinoma of the pancreas with multiple malignant liver cysts. The patient's mother, sister, and niece had ADPKD, and the patient's sister also died of pancreatic cystadenocarcinoma. We believe that the development of these two disease entities in which the primary pathology is cyst formation has a genetic association. (Gastroenterology 1997 Jun;112(6):2104-7) 相似文献

Pheochromocytoma and paraganglioma: comparison of MR imaging with CT and I-131 MIBG scintigraphy 总被引:6,自引:0,他引:6
To ascertain the magnetic resonance (MR) imaging characteristics of pheochromocytomas and paragangliomas and to compare MR with computed tomography (CT) and iodine-131 metaiodobenzylguanidine (I-131 MIBG), 19 patients (18 with pheochromocytomas, one with a paraganglioma) were studied. The 18 patients with pheochromocytomas had had positive findings with I-131 MIBG scintigraphy. Abdominal pheochromocytomas were generally hypointense compared with normal liver on T1-weighted MR images and extremely hyperintense on T2-weighted MR images. MR imaging was preferable to CT in the evaluation of primary pheochromocytomas due to superior tissue characterization, particularly in the patient with hypertension and borderline catecholamine levels. For patients with recurrent or metastatic disease, the data suggest that I-131 MIBG scintigraphy is the examination of choice. 相似文献
