Methods:108 patients with thyroid cancer treated in our hospital between January 2013 and February 2016 were collected and divided into I–II stage thyroid cancer group (n=39), III stage thyroid cancer group (n=55) and IV stage thyroid cancer group (n=14) according to TNM stage;56 patients diagnosed with thyroid adenoma after physical examination in our hospital during the same period were selected as control group. Enzyme-linked immunosorbent assay (ELISA) was used to determine serum galectin-3 and midkine levels of all groups;fluorescence quantitative PCR was used to determine proliferation gene and invasion gene mRNA expression in tumor tissue;Pearson test was used to analyze the correlation of serum galectin-3 and midkine levels with proliferation and invasion gene mRNA expression in patients with thyroid cancer. Results:Serum galectin-3 and midkine levels of patients with thyroid cancer were higher than those of control group (P<0.05), and the higher the tumor stage, the higher the serum galectin-3 and midkine levels;proliferation genes CyclinD1, BCL-2 and survivin mRNA expression in tumor tissue of patients with thyroid cancer were higher than those of control group (P<0.05) while p27 mRNA expression was lower than that of control group (P<0.05), invasion gene E-cadherin mRNA expression was lower than that of control group (P<0.05) while S100A4 and SATB1 mRNA expression were higher than those of control group (P<0.05), and the higher the tumor stage, the more significant the change of the above gene mRNA expression;Pearson test showed that serum galectin-3 and midkine levels in patients with thyroid cancer were correlated with proliferation and invasion gene expression in tumor tissue. Conclusions:Serum galectin-3 and midkine levels can directly reflect the malignant degree of thyroid cancer, and is expected to become the new means for early disease diagnosis, curative effect evaluation and prognosis judgment.展开更多

Here, we explored its interaction with the serum galectin-3 and vascular complications. Methods We conducted a population-based cross-sectional survey in Zhejiang, China involving 165 men and 119 women (age range, 43-84 years), investigating the relationship between serum galectin-3 and vascular disease in patients with T2DM. Results Serum galectin-3 was higher in subjects with T2DM than that in control participants (27.4 vs. 17.6 ng/ml, P 〈0.001). Compared with subjects with galectin-3 values in the lowest quartile, those with values in the highest quartile had an increased likelihood of vascular complications (4th quartile odds ratio (OR) 2.52, 95% confidence interval (CI), 1.25- 4.07). Increased risk of micro- or macrovascular complications corrrelated with serum galectin-3 concentration (ORs 11.4 and 8.5, respectively). An increased number of vascular complications was associated with high serum galectin-3 levels (P 〈0.05). Patients with serum galectin-3 levels 〉25 ng/ml had an elevated risk of diabetes relative to patients with levels 〈10 ng/ml (OR for any vascular complication 2.64, for heart failure 3.97, for nephropathy 4.09, for peripheral arterial disease (PAD) 4.18; all P 〈0.05). Complication risk was higher in patients with neurogenic, stroke, or retinopathy complications, but this difference was not significant after risk factor adjustment. Serum galectin-3 levels correlated with diabetes duration, C-reactive protein (CRP) levels, and albuminuria. Conclusion High galectin-3 values were associated with increased odds of developing heart failure, nephropathy, and peripheral arterial disease in patients with T2DM.展开更多

Pathologic studies confna'ned that different degree of myocardial fibrosis existed in various types of KD. Myocardial fibrosis is an important contributor to the pathophysiology of left ventricular remodeling. Recently, galectin-3 (Gal-3) as a marker of cardiac fibrosis and heart failure was approved by the US FDA. The aim of this study was to evaluate the changes of serum level of Gal-3 in chronic KD (CKD) mad their clinical implications. Methods: The levels of serum Gal-3 were measured by using enzyme-linked immunosorbent assay (ELISA) in 37 CKD patients and 32 healthy controls. Echocardiography was used to determine parameter of left ventricular ejection fraction (LVEF) and left ventricular end-diastolic dimension (LVEDD). Results: The serum concentration of Gal-3 ([95.81:i:18.99] ng/ml versus [48.16-+11.09] ng/ml, t=6,906, P〈0.001) and LVEDD ([60.46+7.63] mm versus (42.69^-10.66) ram, t=3.61, P〈0.01) were significantly higher, while LVEF ([42.69-J:10.661% versus [62.16~6.381%, t=4.679, P〈0.01) were significantly lower in CKD patients compared with healthy controls. A negativecorrelation was found between elevated Gal-3 and lower LVEF (r=--0.882, P〈0.001) and a positive correlation was found between elevated Gal-3 levels and enlarged LVEDD (r=0.834, P〈0.001) or higher NYHA class (r=0.854, P〈0.01) in CKD patients. Conclusion: Serum concentration of Gal-3 is strongly correlated with poorer left ventricular systolic function, enlarged LVEDD and higher New York Heart Association (NYHA) class, which may provide indirectly diagnostic information on myocardial fibrosis and heart function in CKD patients展开更多

文摘Keshan disease (KD) is a fatal endemic dilated cardiomyopathy with unclear etiology and pathogenesis, and a high mortality in China. Pathologic studies confna'ned that different degree of myocardial fibrosis existed in various types of KD. Myocardial fibrosis is an important contributor to the pathophysiology of left ventricular remodeling. Recently, galectin-3 (Gal-3) as a marker of cardiac fibrosis and heart failure was approved by the US FDA. The aim of this study was to evaluate the changes of serum level of Gal-3 in chronic KD (CKD) mad their clinical implications. Methods: The levels of serum Gal-3 were measured by using enzyme-linked immunosorbent assay (ELISA) in 37 CKD patients and 32 healthy controls. Echocardiography was used to determine parameter of left ventricular ejection fraction (LVEF) and left ventricular end-diastolic dimension (LVEDD). Results: The serum concentration of Gal-3 ([95.81:i:18.99] ng/ml versus [48.16-+11.09] ng/ml, t=6,906, P〈0.001) and LVEDD ([60.46+7.63] mm versus (42.69^-10.66) ram, t=3.61, P〈0.01) were significantly higher, while LVEF ([42.69-J:10.661% versus [62.16~6.381%, t=4.679, P〈0.01) were significantly lower in CKD patients compared with healthy controls. A negativecorrelation was found between elevated Gal-3 and lower LVEF (r=--0.882, P〈0.001) and a positive correlation was found between elevated Gal-3 levels and enlarged LVEDD (r=0.834, P〈0.001) or higher NYHA class (r=0.854, P〈0.01) in CKD patients. Conclusion: Serum concentration of Gal-3 is strongly correlated with poorer left ventricular systolic function, enlarged LVEDD and higher New York Heart Association (NYHA) class, which may provide indirectly diagnostic information on myocardial fibrosis and heart function in CKD patients
