Renal expression of macrophage migration inhibitory factor in children with Henoch-Sch-nlein purpura nephritis / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To examine the expression of macrophage migration inhibitory factor (MIF) in renal tissues obtained from children with Henoch-Sch-nlein purpura nephritis (HSPN).</p><p><b>METHODS</b>The renal tissue samples were obtained from 11 children with different pathological grades of HSPN and 8 children with thin glomerular basement membrane disease (controls). The MIF expression was measured by immunohistochemistry. The correlation between MIF expression and 24 hrs urinary protein excretions was evaluated using a linear correlation analysis.</p><p><b>RESULTS</b>MIF expression was seldom found in renal tissues obtained from controls. However, a significantly increased MIF expression was found and was concordant with the increased severity of renal pathology in renal tissues obtained from children with HSPN. The MIF expression in renal tissues of grade III-IV of renal pathology was significantly higher than that in grade I-II in children with HSPN (p<0.01). In children with HSPN, there was an increased MIF expression in renal tissues with crescent formation and inflammatory cell infiltration. Renal MIF expression was significantly positively correlated with 24 hrs urinary protein excretions in children with HSPN (p<0.01).</p><p><b>CONCLUSIONS</b>MIF may play an important role in renal injury of HSPN. Up-regulation of MIF expression may reflect the degree of renal lesions in HSPN.</p>

Serum Levels of Helper T Cell 1/Helper T Cell 2 Cytokines in Children with Hepatitis B Virus-Associated Glomerulonephritis and Its Clinical Significance / 实用儿科临床杂志

Objective To investigate the significance of helper T cell 1(Th1)/Th2 cytokines unbalance in children with hepatitis B virus-associated glomerulonephritis(HBV-GN).Methods The serum levels of interferon-gamma(IFN-?),interleukin-2(IL-2) and IL-4 were determined in 22 children with HBV-GN and 18 children with HBV by enzyme-linked immunosorbent assay(ELISA),respectively,and the difference of Th1/Th2 cytokines in the 2 groups.Results Serum levels of IL-2 and IFN-? in children with HBV-GN were decreased(P

Effects and Safety of Hemoperfusion Therapy on Infants with Tetramine Poisoning / 实用儿科临床杂志

Objective To explore the effects and safety of hemoperfusion(HP) therapy on tetramine poisoning in infants.Methods Thirty-five infants with tetramine poisoning were divided into two groups: HP group(n=18) and non HP group(n=17).The changes of blood tetramine concentration and clinical symptom improving of both groups after the treatment were observed together with the adverse effects of HP group.Results The average blood tetramine concentration of HP group was higher than that of non HP group(342.2?333.4 vs 117.9?50.8 ?g/L,P
