RESUMEN
Abdominal aortic aneurysms(AAAs) is the most common aneurysm,and usually characterized by less symptom.While ruptured AAAs leads to high mortality.Abdominal ultrasonography can effectively detect AAA,decrease the AAAs-related mortality.However,screening AAAs causes some adverse outcomes,including psychological distress and immediate harms in treatment.Meanwhile,the prevalence of AAAs in sex and age is significantly different.Therefore,a reasonable and effective screening strategy is very important.This article search random control trials,systematic reviews,meta-analysis and guidelines in screening AAAs to obtain a reasonable screening strategy.
RESUMEN
Uninephrectomy was performed in a ll rats of this study, and diabetic model was induced in partial rats by streptozo tocin. Then these rats were divided into uninephrectomy group, diabetes group an d benazepril-treated diabetes group. After 4 weeks, renal tubulo-interstitial morphological change was observed and type Ⅳ collagen, fibronectin and transfor ming growth factor ? 1 (TGF-? 1) proteins as well as TGF-? 1 mRNA were d etermined. The results suggested that benazepril played a protective role in ren al tubulo-interstitial injury, which was associated partially with down-regula ted overexpression of TGF-? 1.
RESUMEN
Objective To investigate effects of different dialyzed membrane on transforming growth factor(TGF-?1 ) and monocyte chemoattractant protein(MCP-1 ) plasma levels in maintenance hemodialysis (MHD) patients. Methods The plasma concentrations of TGF-?1 and MCP-1 were measured by ELISA assay in well-matched uremic patients undergoing maintenance hemodialysis with either cuprophane (CU, n = 27 ) or polysulfone (PSU, n = 25 ). Results Compared with controls (50. 2 ? 5. 7 ng/ml), the patients on CU(82. 9 ? 9. 8 ng/ml) and PSU (65. 5 ? 6. 5 ng/ml)membranes dialysis had significantly higher mean TGF-?1 concentration (P
