A relationship between cyclooxygenase-2 (COX-2) expression and the pathogenesis of colorectal cancer has been reported in recent studies. Moreover, it has been indicated that COX-2 expression may have a prognostic role in colorectal cancer patients. In this study, we investigated the prognostic significance of COX-2 expression in 83 patients with colorectal cancer. COX-2 expression was assessed using immunohistochemical methods and was evaluated by grading both staining intensity and staining extension. The relationships between COX-2 expression and clinicopathological features of the patients and patient survival were evaluated. There was no relationships between COX-2 expression and tumor size (tm < 3 cm or tm > or = 3 cm), tumor histopathological differentiation (poorly differentiated or moderately + well differentiated), number of metastatic lymph nodes (< 4 or 3 > or = 4), histopathology of the tumor, localization of the tumor (colon or rectum), distant metastasis, and vascular invasion of the tumor. In the multivariate analysis, COX-2 expression was not found as an independent prognostic factor. We demonstrated that COX-2 expression was not correlated with clinicopathological characteristics of colon carcinoma and disease outcome. 相似文献
We report three patients with Feingold 2 syndrome with the novel features of growth hormone deficiency associated with adenohypophyseal compression, aortic dilation, phalangeal joint contractures, memory, and sleep problems in addition to the typical features of microcephaly, brachymesophalangy, toe syndactyly, short stature, and cardiac anomalies. Microdeletions of chromosome 13q that include the MIR17HG gene were found in all three. One of the patients was treated successfully with growth hormone. In addition to expanding the phenotype of Feingold 2 syndrome, we suggest management of patients with Feingold 2 syndrome include echocardiography at the time of diagnosis in all patients and consideration of evaluation for growth hormone deficiency in patients with short stature. 相似文献
Heparin is an important polyanionic drug having a wide variety of different biological activities. Substantial research effort has focused on the preparation of improved heparins and heparin analogues that might exhibit higher specificity and decreased side effects. These heparin analogues or heparinoids include sulfated polysaccharides from plant and animal origin, synthetic derivatives of polysaccharides, and acidic oligosaccharides and their small synthetic analogues. The structure, biological activities and therapeutic potential of these heparinoids are discussed. 相似文献
Aim of the work: To evaluate the quality of life (QoL) in Familial Mediterranean Fever (FMF) patients, and determine its association with fatigue, depression, disease severity and other clinical parameters. Patients and methods: Sixty FMF patients were included. QoL was assessed by Short Form-36 (SF-36), depression by Hamilton Depression Scale (HDS), and fatigue by Fatigue severity scale (FSS). Disease severity score and Mutations of the Mediterranean fever (MEFV) gene were assessed. Results: The mean age of patients was 33.73 ± 9.81 years and disease duration 14.6 ± 12.1 years. They were 35 females and 25 males. FMF patients scored significantly higher in FSS (29.9 ± 17.6) and HDS (15.1 ± 8.5) compared to the control (10.6 ± 7.1 and 6.3 ± 9.4; p < 0.0001 respectively) while all SF36 sub-items except mental health were significantly lower (p < 0.05). MEFV gene mutation was present in 49 (81.7%) patients. The visual analogue scale of pain significantly negatively correlated with the FSS (p < 0.0001), HDS (p < 0.0001) and all SF36 sub-items except mental health (p < 0.0001). Disease duration, age of onset, and duration of attacks showed no significant correlation with FSS, HDS and SF36. Delay in diagnosis significantly correlated with FSS (p < 0.0001) and negatively with SF36 sub-items physical role (p = 0.02), general health (p = 0.01) and social functioning (p = 0.03). Age of diagnosis significantly correlated with FSS (p = 0.03) and negatively with SF36-vitality (p = 0.047). There was a significant effect of disease severity on QoL, fatigue and depression (p < 0.05). Conclusion: QoL is associated with fatigue, depression and disease severity in FMF patients. It should be used in routine clinical evaluation as an outcome measure in FMF. 相似文献
Anatomic continuity between the anterior mitral leaflet and the aortic root may predispose those patients with aortic root pathology to functional changes of the mitral valve without any involvement of this valve. A 34-year-old man presented with aortic valve endocarditis. Transthoracic echocardiograpy showed severe aortic regurgitation with a large aortic root abscess. The anterior leaflet of the mitral valve was displaced towards the apex of the heart causing moderate mitral regurgitation. The patient underwent aortic valve replacement with reconstruction of the aortic annulus and ventriculoaortic continuity. This procedure alone restored the mitral valve structure and function without any need for intervention on the mitral valve. Aortic abscess is a serious complication of aortic valve endocarditis and may alter the function of other structures of the heart, especially the mitral valve. Restoration of aortic wall integrity and left ventricular – aortic continuity usually restores the mitral valve structure and function if the valve is unaffected by the infection. A decision on the mitral valve should be made following correction of the aortic pathology. 相似文献
Objective: To investigate the plasma levels of interleukin-4 (IL-4), IL-6, IL-10, tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma), transforming growth factor-beta (TGF-beta), IL-17, IL-35 and suppressor of cytokine signaling 3 (SOCS3) in the women with history of idiopathic recurrent pregnancy loss (RPL) and in the fertile controls.
Methods: This study was conducted with 60 idiopathic RPL cases and 40 age-matched fertile controls. Mid-follicular plasma levels of IL-17, IFN-gamma, TNF-alpha, TGF-beta, IL-6, IL-4, IL-10, SOCS3 and IL-35 were assayed by an enzyme linked immunosorbent assay.
Results: The mean age of RPL and control cases were 31.6?±?0.6 and 32.1?±?0.7 years, respectively. While plasma IL-35 and SOCS3 levels of RPL group were significantly lower than that of the control group; IFN-gamma, TNF-alpha, IL-4, IL-6, IL-10, IL-17 and TGF-beta levels of RPL group were significantly higher than that of the control group. The comparison of cytokine ratios between RPL and control groups indicated significantly high TNF-alpha/IL-10, TNF-alpha/IL-4, IFN-gamma/IL-10, IFN-gamma/IL-6 and IFN-gamma/IL-4 ratios in the RPL group. IL-35/IL-17 ratio was significantly low in the RPL group compared to that in the control group. Overstimulation of TNF-alpha presented moderate influence on recurrent miscarriage risk.
Conclusion: Decreased SOCS3 and IL-35 plasma levels and increased Th1/Th2 cytokine ratios in RPL cases pointed out the supression of anti-inflammatory process and this supression might play an important role in the pathogenesis of idiopathic RPL. 相似文献
