Interleukin 8 (IL-8), is a proinflammatory chemokine, has been reported to have angiogenic activity and to be responsible for tumor-associated angiogenesis in several cancers. In this study, we aimed to study the (IL-8) gene polymorphism in relation with risk development of non small cell lung cancer in Tunisian patient. Two single nucleotide polymorphisms (−251T/A [rs4073], +781C/T [rs2227306]) of the IL-8 gene were screened in 170 patients with NSCLC and 225 healthy controls by PCR–RFLP. 相似文献

One hundred and sixteen percutaneous drainage procedures of the biliary system were performed in a 2-year period. Eight of 9 acutely ill patients with the diagnosis of acute suppurative cholangitis were successfully treated nonoperatively. They represented 26% of all patients with benign or postsurgical obstruction referred for biliary decompression. Conversely, acute suppurative cholangitis only occurred in 2.3% of patients with underlying malignant disease. These observations are considered most relevant in predicting the purulent nature of the disease, with further implications for patient management. Early recognition and prompt decompression of the biliary system are mandatory, along with the appropriate antibiotic coverage. Our experience compares favorably with surgical results and the procedure is proposed as the method of choice for the initial treatment of acute suppurative cholangitis. 相似文献

Background. Coronary artery disease is the leading cause of death in emerging countries. Contemporary data about clinical profile and prognosis in Tunisian patients presenting for non ST-elevation acute coronary syndrome (NSTE-ACS) are lacking. Aim. We sought to study the risk profile and 3-year mortality predictors in Tunisian patients presenting for NSTE-ACS in the contemporary setting. Methods. In this single center study, data about all consecutive patients presenting to our center for NSTE-ACS from April 2014 to July 2016 were extracted and outcomes exhaustively updated. 3-year mortality predictors were determined by multivariable survival analysis. Results. A total of 340 patients were included, of which 204 (61.8%) were male. Mean age was 63.6 ± 10.3 years. Prevalence of diabetes mellitus, hypertension and smoking was 57.3%, 62.4%, and 45.3%, respectively. In-hospital, 6, 12 and 36-month mortality rate was 2.3%, 3.2%, 7.1% and 15.2%, respectively. In multivariable survival analysis, independent predictors of death were age >75 (HR=5.45, 95% CI: 2.9-10.03, p<0.001), ST-segment deviation (HR=1.86, 95% CI: 1.04-3.33, p=0.036), anemia (HR=2.56, 95% CI: 1.41-4.67, p=0.002), left ventricular ejection fraction (LVEF) <40% (HR=3.5, 95% CI: 1.84-6.67, p<0.001) and a Global Registry of Acute Coronary Events (GRACE) score ≥140 (HR=2.38, 95% CI: 1.02-5.57, p=0.044) Conclusion. In Tunisian patients presenting for NSTE-ACS, long-term mortality was high. Advanced age, ST-segment deviation, anemia, LVEF <40% and a GRACE score ≥140 were independent long-term predictors of death. 相似文献

The aim of this study is to evaluate new echocardiographic modes in diagnosis of arrhythmogenic right ventricular dysplasia (ARVD). Our study is prospective, including ten patients with ARVD and a control group of ten healthy subjects. Transthoracic echocardiography included evaluation of classical criteria's, cross sectional measurements of the right ventricular. M mode and pulsed tissue Doppler techniques were used for quantitative measurement of tricuspid annular motion at the lateral and septal positions. Assessed by M mode, the total amplitude of the tricuspid annular motion was decreased in the lateral and septal positions in the patients compared with the controls. The tissue Doppler velocity pattern showed decreased early diastolic peak annular (Ea) velocity and an accompanying decrease in early (Ea) to late diastolic(Aa) velocity ratio in all positions; the systolic annular velocity was decreased only in the lateral position. Tricuspid annular measurement are valuable, easy to obtain and allow quantitative assessment of right ventricular function. ARVC patients showed an abnormal velocity pattern that may be an early but non specific sign of disease. 相似文献

Angiostatin selectively inhibits signaling by hepatocyte growth factor in endothelial and smooth muscle cells 总被引:6,自引:1,他引:6
Angiostatin, an inhibitor of angiogenesis, contains 3 to 4 kringle domains that are derived from proteolytic cleavage of plasminogen. The antiangiogenic effects of angiostatin occur, in part, from its inhibition of endothelial cell surface adenosine triphosphate synthase, integrin functions, and pericellular proteolysis. Angiostatin has structural similarities to hepatocyte growth factor (HGF; "scatter factor"), a promoter of angiogenesis, that induces proliferation and migration of both endothelial and smooth muscle cells via its cell surface receptor, c-met. We hypothesized that angiostatin might block HGF-induced signaling in endothelial and smooth muscle cells. Angiostatin inhibited HGF-induced phosphorylation of c-met, Akt, and ERK1/2. Angiostatin also significantly inhibited proliferation of human umbilical vein endothelial cells (HUVECs) induced by HGF. In contrast, angiostatin did not inhibit vascular endothelial growth factor (VEGF)-or basic fibroblast growth factor (bFGF)-induced signaling events or HUVEC proliferation. Angiostatin bound to immobilized truncated c-met produced by A431 cells and could be immunoprecipitated as a complex with soluble c-met. HGF inhibited the binding of (125)I-angiostatin to HUVECs. Soluble c-met, produced by several tumor cell lines, could inhibit the antiangiogenic effect of angiostatin. The disruption of HGF/c-met signaling is a novel mechanism for the antiangiogenic effect of angiostatin. 相似文献

Heart failure (HF), the cardiovascular epidemic of the twenty-first century, is associated with significant comorbidities and high mortality. The prevalence of HF is estimated around 6.5 million people and is expected to increase to 8 million by the year 2030. The associated costs to care for these patients continue to increase. Despite the advancement of pharmacologic therapy with significant improvement in morbidity and mortality, the 5-year survival for heart failure still stands at 61%. The challenges faced by HF patients include difficulty with lifestyle modifications, nonadherence to complex medical regimens, financial limitations, lack of access to medical care, and unfavorable side effects. The sickest HF patients, who are ACC/AHA stage D, have advanced therapeutic options such as left ventricular assist devices and orthotopic heart transplant; however, the majority of patients are ACC/AHA stage C and/or not candidates for such advanced care. With constraints placed on hospitals by Medicare on HF readmissions as well as the multiple comorbidities imposed by this disease, intense interest is focused on the development of implantable devices as add-on therapy. This review discusses the innovative devices under varying stages of investigation or approved for monitoring and treatment of HF. 相似文献
