Colonic carcinoma metastatic to the kidney is very rare. The usual anatomical localization for secondary renal neoplasms is the renal cortex. We report a case of sigmoid colon carcinoma with unilateral kidney metastasis localized only in the renal papillae without obvious metastatic disease. 相似文献

Aim: Plasma visfatin levels are elevated in diabetic nephropathy in parallel to the severity of proteinuria and glomerular filtration rate. The aim of this study was to find out whether the renin–angiotensin–aldosterone system (RAAS) blockage has any effect on the plasma visfatin levels. Methods: Thirty‐two patients with diabetic proteinuria (>500 mg/day) with a normal glomerular filtration rate (GFR) and 33 healthy subjects were enrolled. Patients were treated with ramipril 5 mg daily for 2 months. Proteinuria, GFR, high‐sensitivity C‐reactive protein (hsCRP), visfatin, flow‐mediated dilatation (FMD) and homeostasis model assessment of insulin resistance (HOMA‐IR) index measurements were performed both before and after the treatment. Results: The plasma visfatin, and hsCRP levels of the patients were significantly higher and the FMD was significantly lower (P < 0.001 for all). The visfatin levels were significantly correlated to FMD, systolic and diastolic blood pressures, proteinuria, eGFR, HOMA‐IR and hsCRP. Ramipril treatment resulted in a significant decrease in plasma visfatin, proteinuria, hsCRP, HOMA‐IR and increase in FMD (P < 0.001) in patients (P < 0.001 for all). Conclusion: The present study suggests that plasma visfatin levels are related to the endothelial functions, inflammation and the severity of proteinuria in diabetic nephropathy. Treatment with ramipril causes a significant decrease in visfatin levels along with the improvement of proteinuria, endothelial dysfunction and inflammatory state in diabetic nephropathy. 相似文献

目的 观察阻塞性睡眠呼吸暂停低通气综合征(Obstructive sleep apnea hypopnea syndrome,OSAHS)对2型糖尿病患者血糖水平及夜间血糖漂移的影响。 方法 选择2型糖尿病(Type 2 diabetes mellitus,T2DM)伴OSAHS患者31例及单纯T2DM患者18例,所有患者应用动态血糖监测系统(CGMS)连续进行动态血糖监测3 d,比较2组患者夜间血糖、空腹血糖、24 h血糖、夜间MAGE(Mean amplitude of plasma glucose excursion)、白天MAGE、24 h MAGE以及糖化血红蛋白(hemoglycoglobulin, GhBA1c)。 结果 单纯T2DM组及T2DM伴OSAHS组性别、年龄、病程差异无统计学意义,而体重指数、腰围、颈围差异有统计学意义(P0.05),体重指数、腰围、颈围校正后,T2DM伴OSAHS组患者夜间MAGE、24 h MAGE显著高于单纯T2DM组(P0.01),两组患者夜间血糖、空腹血糖、24 h血糖、白天MAGE及GhBA1c差异也有统计学意义(P0.05)。 结论 OSAHS引起T2DM夜间血糖、夜间MAGE增高,从而影响全天血糖及全天MAGE。 相似文献

To determine the prevalence and significance of a systolic mitralmurmur heard after a first acute myocardial infarction (MI),we studied 186 consecutive patients in the coronary care unit(CCU) during a one-year period. Fifteen patients had a murmuras a result of mitral regurgitation (MR) (prevalence 8%) documentedby colour Doppler flow imaging. It was heard before the thirdday of hospitalization in 10 (67%) patients, and on the thirdday itself in the remainder. The severity of MR was graded semi-quantitatively:moderate in 12 (80%) patients, and mild, moderate to severeand severe in three respectivety. The direction of the MR jet,determined by colour flow imaging, improved the informationobtained by two-dimensional echocardiography (2D echo) thatcould only diagnose mitral leaflet abnormality in seven (47%)patients. in 10 of 15 (67%) patients, the 2D echo ejection fractionwas 40% and in eight (53%) the wall motion score obtained byanalysing 11 left ventricular (LV) segments was 8. Two (13%)patients died in tile CCU, four (27%) had LV failure, one anginaand eight (53%) remained asymptomaric in the hospital. Of 171patients without a systolic murmur, 22 (13%) had LV failure,13 (8%) angina and 25 (15%) died during the in-hospital stay(P-NS for these complications between patients with and withoutMR murmur). During a follow-up of 1224 months, one MRpatient died, and seven (47%) remained asymptomatic. We conclude that the prevalence of MR systolic murmurs in acuteMI patients is low. The LV function and the prognosis of a majorityof these patients is rather good. 相似文献

AIM: The information currently available suggests that nonadrenergic noncholinergic (NANC) transmitters, particularly nitric oxide, are involved in the relaxation of penile erectile tissues. Platelet-activating factor (PAF) is a chemical mediator and is involved in many physiological and pathophysiological events. It is well known that several of the vascular actions of PAF are mediated by the generation of nitric oxide. We designed this study to test the hypothesis that PAF has an effect on NANC responses in rabbit corpus cavernosum strips. METHODS: Rabbit corpus cavernosum strips were precontracted with phenylephrine (10(-5) mol/L). Isometric tension changes produced by carbachol (10(-9)-10(-5) mol/L), sodium nitroprusside (10(-8)-10(-5) mol/L) and electrical field stimulation (for 10 s at sequential frequencies of 2, 4, 8, 16, and 32 Hz as square-wave pulses of 50 mV) were recorded with a pressure transducer. These relaxations were compared to those obtained in the presence of PAF. RESULTS: PAF had no effect on endothelium-dependent, endothelium-independent or electrical field stimulation-induced NANC relaxation responses in isolated rabbit corpus cavernosum strips. There was no statistically significant difference between the pD(2) and E(max) values for carbachol or sodium nitroprusside in the presence of PAF. CONCLUSIONS: Our results suggest that PAF does not modify the endothelium-dependent, endothelium-independent or electrical field stimulation-induced NANC relaxation responses in isolated rabbit corpus cavernosum strips. 相似文献

Prostatic ductal adenocarcinoma represents a rare histological variant of prostatic carcinoma with features of a papillary lesion at cystoscopy. There are conflicts regarding the existence, origin, staging, grading, treatment and clinical behavior of this tumor. The aim of the present study is to examine the expression of Bcl-2 and p53 in prostatic ductal adenocarcinoma and to evaluate its origin by analyzing prostate specific antigen, prostate specific acid phosphatase, cytokeratins, epithelial membrane antigen and carcinoembryonic antigen expressions. The results confirmed the expression of prostate specific antigen and prostate specific acid phosphatase in prostatic ductal adenocarcinoma. The demonstrated expression of Bcl-2 was predominant in the better-differentiated tumor. Bcl-2 expression appears not to be associated with neuroendocrine differentiation as assessed by chromogranin A reactivity. Thus, the first case of a prostatic ductal adenocarcinoma showing Bcl-2 expression is presented. The tumor was negative for p53. 相似文献
