RESUMEN
Objective:To investigate the diagnostic values of human epididymis protein 4 (HE4), endothelial cell specific molecule-1 (ESM-1) and epidermal growth factor receptor (EGFR) for lung cancer.Methods:The clinical data of 90 patients with lung cancer and 50 patients with benign lung diseases diagnosed by the pathological examination in Tangshan People's Hospital from December 2019 to January 2021 were retrospectively analyzed, and 40 healthy physical examiners in the same period were selected as the controls. The serum HE4 levels were detected by electrochemiluminescence method. The serum ESM-1 and EGFR levels were tested by enzyme-linked immunosorbent assay. The differences in serum HE4, ESM-1 and EGFR levels between the three groups were compared; logistic regression analysis was used to screen out the effective indicators for the diagnosis of lung cancer and to construct a prediction model for the diagnosis of lung cancer. Using pathological diagnosis result as the gold standard, the receiver operating characteristic (ROC) curve was drawn, and the diagnostic efficacy of indicators for lung cancer was evaluated.Results:The levels of serum HE4 in lung cancer group, benign lung diseases group and healthy control group were 119.55 pmol/L (82.06 pmol/L, 189.00 pmol/L), 58.84 pmol/L (45.62 pmol/L, 69.41 pmol/L) and 42.67 pmol/L (37.09 pmol/L, 51.84 pmol/L), the levels of ESM-1 were 33.00 ng/ml (25.85 ng/ml, 47.40 ng/ml), 20.14 ng/ml (11.93 ng/ml, 28.90 ng/ml) and 15.39 ng/ml (11.84 ng/ml, 20.19 ng/ml), and the levels of EGFR were 46.60 pg/ml (37.45 pg/ml, 58.98 pg/ml), 32.77 pg/ml (26.27 pg/ml, 40.86 pg/ml) and 30.43 pg/ml (27.54 pg/ml, 35.75 pg/ml), and the differences in each indicator among the three groups were statistically significant (all P < 0.001). The levels of serum HE4, ESM-1 and EGFR in lung cancer group were higher than those in benign lung diseases group and healthy control group. In patients with lung cancer, logistic regression analysis was performed with HE4 (X 1), ESM-1 (X 2) and EGFR (X 3) as the independent variables and pathological diagnosis as the dependent variable, and a lung cancer prediction regression model was established: P = 0.171X 1+0.351X 2+0.184X 3-24.660. The accuracy of this model in predicting lung cancer could reach 98.5%, and serum HE4, ESM-1 and EGFR were risk factors for the occurrence of lung cancer (all P < 0.05). The area under ROC curve from high to low was HE4 (0.960), ESM-1 (0.942) and EGFR (0.859). The diagnostic sensitivity of serum HE4 63.67 pmol/L for lung cancer was 86.7%, and the specificity was 97.5%. Both serum HE4 ( r = 0.304, P = 0.004) and ESM-1 ( r = 0.416, P < 0.001) were correlated with EGFR. Conclusions:Serum HE4, ESM-1 and EGFR can be used as effective indicators for the diagnosis of lung cancer, and the prediction model established based on the three serum tumor markers is of good value for the diagnosis and prediction of lung cancer.
RESUMEN
Objective This study was to evaluate the values of endothelial cell-specific moleculel (endocan),von Willebrand factor (vWF),and"A disintegrin-like and metalloprotease with thrombospondin type 1 motit"(ADAMTS-13),alone or in combination,in the risk stratification and disease severity assessment of patients with sepsis via comparing the differences of these markers in patients with systemic inflammatory reaction syndrome (SIRS),sepsis,severe sepsis,or septic shock,and healthy volunteers.Methods Clinical data of 301 patients with SIRS or sepsis treated in our Emergency Department from October 2014 to October 2015,were prospectively analyzed.These patients were divided into SIRS,sepsis,severe sepsis,and septic shock groups.40 healthy individuals were selected as control.Endocan,vWF,ADAMTS-13,vWF/ADAMTS-13,and Procalcitonin (PCT) levels were measured,and APACHE Ⅱ score,MEDS score as well as SOFA score were calculated.The all-cause death or survival of each patient was recorded during the 28-day follow-up.Results The endocan,vWF,and vWF/ADAMTS-13 levels significantly increased in patients with SIRS,sepsis,severe sepsis,or septic shock and were positively correlated with disease severity,and were also positively correlated with MEDS score,APACHE Ⅱ score,SOFA score.On the other way,the ADAMTS-13 level gradually declined during disease progression and was negatively correlated with the disease severity,it was also negatively correlated with MEDS score,APACHE Ⅱ score,SOFA score.Conclusions Endocan,vWF,ADAMTS-13,and vWF/ADAMTS-13 ratio are valuable in the risk stratification and disease severity evaluation of sepsis,providing novel sepsis biomarkers in clinic.
RESUMEN
BACKGROUND: Endocan, previously called endothelial cell–specific molecule-1, is a soluble proteoglycan that is secreted from vascular endothelial cells. Elevated plasma endocan levels were shown to be associated with poor cardiovascular outcomes in patients with chronic kidney disease (CKD). We investigated the clinical relevance of plasma and urine endocan levels in patients with immunoglobulin A nephropathy (IgAN). METHODS: Sixty-four patients with IgAN and 20 healthy controls were enrolled in this study. Plasma and urine endocan levels were measured. Clinical parameters, pathologic grades, and renal outcomes were compared among subgroups with different plasma and urine endocan levels. RESULTS: Both plasma and urine endocan levels were significantly higher in patients with IgAN than in controls. Elevated serum phosphorus and C-reactive protein were independent determinants for plasma endocan, and elevated C-reactive protein was also an independent determinant for urine endocan levels in multivariate analysis. Plasma endocan level was not significantly different across CKD stages, but patients with higher plasma endocan levels showed adverse renal outcome. Urine endocan levels were also elevated in patients with poor renal function. Cox proportional hazard models showed that high plasma endocan was an independent risk factor for CKD progression after adjusting for the well-known predictors of outcome in patients with IgAN. CONCLUSION: This study suggested that plasma endocan might be useful as a prognostic factor in patients with IgAN.
