RESUMEN
Objective:To investigate the clinical significance of serum resistin in juvenile idiopathic arthritis(JIA) patients.Methods:A prospective observational study was performed and 32 cases of patients with systemic onset JIA(SOJIA)(SOJIA group) in children admitted to the nephrorheumatology and outpatient were enrolled at Children′s Hospital of Shanghai between October 2013 and September 2015, 52 cases of other types(N-SOJIA group), and 33 cases of other rheumatic diseases(other rheumatic diseases group), 30 cases of children undergoing health checkups in the child health outpatient clinic(healthy control group)were involved as well.Serum resistin levels were measured by enzyme-linked immunosorbent assay(ELISA), and comprehensive analysis was carried out with clinical data and related laboratory findings.The basic data of gender, age and body mass index(BMI) of each group were collected, and the duration of disease in children in JIA group, rheumatoid factor, antinuclear antibody, white blood cell, hemoglobin, platelet, C reacting protein(CRP), erythrocyte sedimentation rate(ESR), clinical manifestations and current drug use were collected.Using the receiver operating characteristic(ROC)curve analysis of sensitivity and specificity resistin levels in diagnostic systemic juvenile idiopathic arthritis.Results:There was no statistically significant difference in the age, gender and BMI of children in SOJIA group, N-SOJIA group, other rheumatism group and healthy control group.Children in the SOJIA group and the N-SOJIA group had arthritis in clinical manifestations.Fever and rash were more common in the SOJIA group, and the difference was statistically significant ( P<0.01). Laboratory results showed that the sedimentation rates of white blood cells, CRP, and red blood cells were in the SOJIA group was significantly elevated.The antinuclear antibody was mainly found in the N-SOJIA group with a higher positive rate ( P<0.05). The mean serum resistin in the SOJIA group [(17.98±13.78) mg/L] was higher compared to the healthy control group [(1.84±1.66) mg/L], other rheumatic diseases group [(8.00±6.28) mg/L]and the N-SOJIA group [(9.86±6.11) mg/L], the differences were statistically significant ( F=21.625, P<0.01). Resistin was positively correlated with white blood cells and CRP( r=0.532, 0.351, all P<0.05), and had no correlation with BMI, hemoglobin, platelets, and ESR( r=0.059, -0.176, 0.152, 0.203, all P>0.05). Based on serum resistin≥5.55 mg/L as the positive threshold value, the area under ROC curve was 0.802, and the sensitivity and specificity in diagnosis of SOJIA was 96.9% and 49.6%, respectively. Conclusions:Serum resistin is increased in patients with JIA, especially in SOJIA increased significantly; Serum resistin can be used for the diagnosis of SOJIA, and ≥5.55 mg/L can be a suitable cut-off level.
RESUMEN
Objective To investigate the diagnostic and prognostic value of serum soluble CD163 (sCD163 )and the positive rate of membrane -bound CD163 (mCD163 )in peripheral blood mononuclear cells (PBMC)in children with infection -associated hemophagocytic syndrome (IAHS).Methods Between July 2012 and June 2016,26 pediatric patients with IAHS (IAHS group)and 28 pediatric patients with sepsis(sepsis group)admitted to Children′s Hospital Affiliated to Shanghai Jiaotong University were selected,and 20 healthy children were taken as healthy control group. Sandwich enzyme linked immunosorbent assay was used to detect serum sCD163 .The population of circulating mCD163 positive monocytes was determined by using flow cytometry.Receiver operating characteristic (ROC)curves were used to evaluate the diagnostic and prognostic values of sCD163 and mCD163 in children with IAHS compared with the diagnos-tic and prognostic values of plasma ferritin,and so on.Results The serum levels of sCD163 in patients of IAHS group, sepsis group and healthy control group were (1264 ±538)mg/L,(862 ±332)mg/L,(610 ±316)mg/L,respective-ly.And the population of mCD163 -positive PBMC in patients of IAHS group,sepsis group and healthy control group was (88.3 ±9.7)%,(68.5 ±18.3)%,(28.9 ±5.2)%,respectively.Both serum sCD163 and the population of mCD163 -positive PBMC were significantly higher in IAHS group compared with those of sepsis group (t =2.031 ,P =0.048;t =3.191 ,P =0.002,respectively).The serum sCD163 and population of mCD163 -positive PBMC in sepsis group were higher than controls (t =3.848,P =0.002;t =4.049,P =0.000,respectively).Moreover,the areas under the ROC curve (AUC)for the mCD163 ,sCD163 ,were 0.853(P =0.013),0.762(P =0.004),0.755(P =0.049),respec-tively.mCD163 at a cutoff of 83.7% had a high diagnosis sensitivity (81 .8%)and specificity (72.4%).The optimal cutoff values of sCD163 and ferritin for predicting IAHS was 888 mg/L (sensitivity 66.7% and specificity 63.3%)and 2880 μg/L (sensitivity 80.0% and specificity 54.5%).In addition,the serum level of sCD163 and the population of mCD163 -positive PBMCs were significantly increased in acute phase and decreased in recovery phase[(1553 ±542) mg/L vs.(866 ±92)mg/L,(91 .0 ±6.4)% vs.(79.0 ±4.6)%,t =2.450,χ2 =3.419,P =0.036,0.007]in IAHS group.Furthermore,subgroup analysis indicated that the serum level of sCD163 and the population of mCD163 -positive PBMCs were significantly higher in dead patients than those in survived patients [(1748.91 ±518.17)mg/L vs. (909.69 ±171 .35)mg/L,t =3.070,P =0.011 ;(93.50 ±8.42)% vs.(77.30 ±3.28)%,χ2 =3.005,P =0.024, respectively].Conclusion Serum sCD163 and the population of mCD163 -positive PMSCs are specific and validity bio-markers for early diagnosis of IAHS,which also are associated with treatment response assessment and prognostic analy-sis in IAHS.

RESUMEN
Objective To investigate the clinical application value of insulin intensive therapy for hyperglycemia after craniocerebral trauma by analyzing its improving effect of illness state and inflammatory cytokines.Methods 62 cases of patients with severe craniocerebral injury were retrospectively studied,in which 31 cases were treated with conventional insulin therapy (normal group),and the other 31 cases were treated with insulin intensive therapy(intensive group).Glasgow coma scale(GCS) score,injury severity score(ISS) and acute physiology and chronic health(APACHE Ⅱ)score were before and after treatment.At the same time,the fasting peripheral blood of each patients were extracted to detect blood sugar concentration and serum inflammatory cytokine levels of IL-6,IL-10,TNF-alpha,hs-CRP.In addition,3 months to 2 years' follow-up were completed after treatment to record the infection rate and mortality rate.Results There was no significant difference in the indexes evaluated between groups before treatment(P ＞ 0.05).After treatment,the GCS score of intensive group was higher than that of normal group while the ISS score and APACHE Ⅱ score were opposite,and all the difference was significant(t =2.448,3.174,5.430 ; P =0.038,0.024,0.001) ; and the ISS score and APACHE Ⅱ score had positive correlation property with blood sugar content(R2 =0.699 9,0.636 4; P =0.016,0.023).At the same time,the blood sugar concentration and serum inflammatory cytokine levels of IL-6,TNF-alpha,hs-CRP of intensive group was lower than those of normal group while the IL-10 level was opposite,and all indicators had statistical difference(t =3.996,2.259,2.659,4.585 ; P =0.014,0.047,0.031,0.002) ; IL-6,TNF-alpha and hs-CRP had positive correlation property with blood sugar content,while IL-10 negative (R2 =0.635 1,0.678 3,0.534 3,0.584 4 ; P =0.022,0.018,0.041,0.038).In addition,the infection rate and mortality rate of intensive group were all lower than those of normal group,with mortality rate got significant difference (x2 =4.846,2.621 ; P =0.028,0.109).Conclusion Our research result shows that insulin intensive treatment could remit hyperglycemia after traumatic brain injury and control the inflammatory reaction rapidly,which contribute to more stable neuroendocrine system and benefit to the prognosis of patients.
