OBJECTIVETo study the possible relationship between serum ferritin levels and susceptibility to attention deficit hyperactivity disorder (ADHD) in children.
METHODSThe papers relating to the relationship between serum ferritin levels and susceptibility to childhood ADHD were searched in the Database CBM, CNKI, VIP and PubMed. The Meta-analysis software RevMan 5.0 was used for the heterogeneity test and for the pooled OR calculation. Sensitivity and publication bias analysis were performed.
RESULTSFive control studies were included for the Meta analysis, including 258 cases of ADHD and 138 control cases. There was heterogeneity in the studies on the relationship between serum ferritin levels and susceptibility to childhood ADHD (P=0.003). So the studies were analyzed using the random-effect model. The pooled OR of serum ferritin levels and susceptibility to childhood ADHD was -23.09 (95%CI:-33.06-13.13; P<0.00001). The funnel plots did not indicate the existence of publication bias.
CONCLUSIONSThe results from present Meta analysis can prove that serum ferritin levels are associated with susceptibility to childhood ADHD.

OBJECTIVETo investigate whether serum ferritin (SF) level may be used as a indicator for predicting mortality of patients with myelodysplastic syndrome (MDS).
METHODSA total of 151 patients with MDS were followed up in our study, their blood routine indicators, bone marrow blasts and SF level were detected. All of the patients were divided into the dead group and survival group.
RESULTSThe average survival time of all patients was 30.0 ± 10.86 months. There were statistical differences in age, IPSS score, chromosome grouping and SF level between 2 groups (P < 0.05). COX model analysis showed that age, MDS type, IPSS score, chromosome grouping and SF level all were related with mortality of patients with MDS, which were risk factors of death for patients with MDS (P < 0.05). The receiver-operating characteristic curve (ROC) area for SF was 0.826 with a Cut off value of 622.95, the sensitivity and specificity was 77.5% and 75% respectively. Log-rank test showed that the mortalities of patients with different levels of SF were statistically and very significantly different (P < 0.01).
CONCLUSIONThe age, IPSS score, chromosome grouping and SF level closely correct with mortality of the patients with MDS, the SF level may be considered as a predictor of death for MDS patients.

OBJECTIVETo investigate the expression level of erythropoietin (EPO) and ferritin before and after treatment of patients with iron deficiency anemia (IDA) so as to explore their clinical significance in diagnosis and discrimination.
METHODSThe EPO and ferritin levels in serum of 37 patients with IDA were determined by using chemiluminescence analysis (CLIA method) and electrical chemiluminescence analysis (ECLIA method), 30 healthy people were randomly selected as normal controls.
RESULTS(1) the sEPO level in IDA patients of group before treatment, group treated for 1 month and group treated for 2 months was higher than that in normal control group (P < 0.05). The level of sEPO of IDA patients in different groups after treatment was lower than that in IDA patients of groups before treatment, along with improvement of anemia status, the level of EPO was gradually reduced, and the level of sEPO in patients of group treated for 3 months was not statistical significant in comparison with that in normal control (P > 0.05). The level of ferritin in IDA patients before and after treatment was lower than that in normal control group (P < 0.05). The level of ferritin in IDA patient of groups after treatment was all higher than that in patients of groups before treatment, but comparision of serum ferritin level in patients of groups after treatment did not show statistical significance. (2) The level of logEPO in IDA patient before and after treatment was negatively related with level of Hb, but the level of ferritin in IDA patients was positively related with the level of Hb before treatment (r = 0.449, P = 0.005), the level of ferritin in patients of different group after treatment and in normal group did not related with level of HB. (3) The level of serum EPO in patients of severe anemia group was obviously higher than that in patients of moderate and mild anemia groups, and along with aggravation of anemia, the EPO level was gradually arised.
CONCLUSIONThe serum EPO is involved in the process of erythrocyte hematopoiesis, and can indicate the level of anemia, its sensitivity for anemia is higher than that of ferritin, and has important clinical value for evaluating status of diseases, observing therapeutic efficacy and judging prognosisi of IDA.

OBJECTIVETo investigate the changes in serum neuron-specific enolase (NSE) and serum ferritin (SF) in patients with pneumoconiosis and their relationship with the onset of pneumoconiosis.
METHODSThe serum NSE and SF levels in the peripheral blood of patients with pneumoconiosis were measured by electrochemical fluorescence immunoassay.
RESULTSThe patients with first-stage pneumoconiosis and second-stage pneumoconiosis had significantly higher serum NSE and SF levels than the control group (23.0264±14.0410 and 44.9776±26.5208 ng/ml vs 8.1480±3.7512 ng/ml, P < 0.05; 267.2515±186.5809 and 579.1371±433.9326 ng/ml vs 120.8613±74.2809 ng/ml, P < 0.05), and the patients with second-stage pneumoconiosis had significantly higher serum NSE and SF levels than those with first-stage pneumoconiosis (P < 0.05). After treatment, the serum NSE level decreased significantly in the patients with pneumoconiosis (21.1675±17.5942 ng/ml vs 33.4490±21.6948 ng/ml, P < 0.05), but it was still significantly higher than that in the control group (P < 0.05). The treatment did not produce significant changes in SF level among these patients (P > 0.05).
CONCLUSIONPatients with pneumoconiosis have elevated serum NSE and SF levels, which may be related to the onset and progression of this disease.

OBJECTIVETo study the diagnostic value of heart rate variability (HRV) in heart dysfunction in children with beta-thalassemia major (β-TM)by examining the changes of HRV in β-TM children.
METHODSA 24 hours Holter monitoring electrocardiogram (Holter) was performed in 21 children with β-TM and 15 healthy children (control group). The time domain and frequency domain indexes of HRV in the two groups were compared. The correlation between serum ferritin levels and HRV was evaluated.
RESULTSThe time domain indexes SDNN, rMSSD and PNN50 and the frequency domain indexes very low frequency (VLF), low frequency (LF) and high frequency (HF) in the β-TM group were significantly lower than in the control group (P<0.05). There was no correlation between serum ferritin level and HRV in children with β-TM.
CONCLUSIONSThe autonomic nerve dysfunction exists in children with β-TM. HRV analysis is useful in the prediction of early cardiac dysfunction in children with β-TM.

This study was aimed to explore the level of glycosylated ferritin in the patients with secondary hemophagocytic lymphohistiocytosis (HLH) and its diagnostic significance. 29 suspected HLH patients from October 2007 to October 2008 were enrolled in the study, and 25 healthy subjects were selected as control. The 29 suspected HLH patients were divided into confirmed group (22 out of 29) and unconfirmed group (7 out of 29) according to HLH-2004 diagnostic criteria. The percentage of glycosylated ferritin in peripheral blood was determined by phytohemagglutinin adsorption assay. The results showed that the median level of total serum ferritin in patients of confirmed group (2897.6+/-1837.2 microg/L) was significantly higher than that in patients of unconfirmed group (653.1+/-249.1 microg/L) (p<0.01), and was also higher than that in controls (414.6+/-212.6 microg/L) (p<0.01). The median percentage of glycosylated ferritin in patients of confirmed group was significantly lower (17.0+/-4.2%) than that in patients of unconfirmed group (40.7+/-4.5%) (p<0.01) and was lower than that in controls (53.6+/-13.3%) (p<0.01). The sensitivity (86.4% vs 77.3%) and specificity (71.4% vs 42.9%) of glycosylated ferritin for the diagnosis of HLH were higher than that of total serum ferritin. In conclusions, glycosylated ferritin may be a helpful marker for the diagnosis of HLH.

OBJECTIVETo establish and evaluate a protein microarray method for combined measurement of serum ferritin (SF) and soluble transferrin receptor (sTfR).
METHODSMicroarrayer was used to print both anti-SF antibodies I and anti-sTfR antibodies I on each protein microarray. Anti-SF antibodies II and anti-sTfR antibodies II were used as detection antibodies and goat antibodies coupled to Cy3 were used as antibodies III. The detection conditions of the quantitative analysis method for simultaneous measurement of SF and sTfR with protein microarray were optimized and evaluated. The protein microarray was compared with commercially available traditional tests with 26 serum samples.
RESULTSBy comparison experiment, mouse monoclonal antibodies were chosen as the probes and contact printing was chosen as the printing method. The concentrations of SF and sTfR probes were 0.5 mg/mL and 0.5 mg/mL respectively, while those of SF and sTfR detection antibodies were 5 μg/mL and 0.36 μg/mL respectively. Intra- and inter-assay variability was between 3.26% and 18.38% for all tests. The regression coefficients comparing protein microarray with traditional test assays were better than 0.81 for SF and sTfR.
CONCLUSIONThe present study has established a protein microarray method for combined measurement of SF and sTfR.
