Henoch-Schönlein purpura (HSP) is a systemic vasculitis mediated by autologous immune complex. Animal models of HSP are scarce. Here, we describe the characteristics of HSP rabbit model in the acute and recovery phase. First, we constructed the HSP rabbit models, and then assessed immunologic indicators of models by enzyme-linked immunosorbent assay and immunoturbidimetry. Histomorphological characteristics were analyzed by haematoxylin-eosin, immunofluorescence and special staining. In the acute stage (24 h) after antigen challenge, the model group rabbits featured skin ecchymosis and abnormal laboratory examination results...

The overall survival time of non-small cell lung cancer (NSCLC) has not improved dramatically in recent decades. An important reason is the lacking of valuable biomarkers. Haptoglobin was reported to have activities of anti-inflammatory, anti-oxidant, autoimmune and tumor angiogenesis. However its potential role as a tumor biomarker was not well recognized. We used an immunoturbidimetry method to measure serum haptoglobin levels in 205 NSCLC patients, and 210 normal healthy controls. We found that serum haptoglobin levels were significantly elevated in NSCLC patients compared with normal healthy controls (1...

BACKGROUND: D-dimers have a high negative predictive value for excluding venous thromboembolism outside of pregnancy but the use in pregnancy remains controversial. A higher cut-off value has been proposed in pregnancy due to a continuous increase across gestation. Fibrin monomer complexes have been considered as an alternative diagnostic tool for exclusion of venous thromboembolism in pregnancy due to their different behavior. OBJECTIVE: We sought to establish normal values of fibrin monomer complexes and D-dimer as a diagnostic tool for the exclusion of venous thromboembolism in pregnancy and examine the effect of maternal and obstetric factors on these markers...

The metabolic syndrome (MetS) is precisely defined and the cardiovascular risk associated with the clustering of its components has been demonstrated in adults. However, data on children and adolescents are still scarce, in part, because of difficulties in transposing the definition from adults. The identification of risk factors for the development of MetS at an early age is essential for prevention purposes with low-grade inflammation acting as a determinant for the association among the MetS components. The aim of this study was to investigate the associations of the MetS with systemic markers of inflammation and ceruloplasmin in a population of adolescents...

BACKGROUND: Glycated hemoglobin (HbA1c) is widely used as a clinical marker of long-term blood glucose concentration in patients with diabetes. The clinical laboratory plays a vital role in the diagnosis and management of diabetes. Many methods for the measurement of HbA1c have been developed based on different analytical principles, often causing discordant results. For this reason, the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) established a reference method for HbA1c assay, namely, high-performance liquid chromatography-mass spectrometry/capillary electrophoresis (HPLC-MS/CE)...

INTRODUCTION: Chronic Kidney Disease (CKD) patients are at high risk of cardiovascular diseases (CVDs). Reduced nitric oxide (NO) bioavailability is a key element in connecting kidney disease to endothelial dysfunction (ED) and cardiovascular (CV) complications. Further, inflammation is implicated in ED in CKD. Besides these, adipose tissue factors were thought to have a role in inflammation and ED in CKD. AIM: It is proposed to evaluate the concentration changes of adipokines, inflammatory and ED markers in CKD patients compared to healthy controls...
