ABSTRACT
Objective To investigate the expression of interleukin-17 (IL-17) in peripheral blood mononuclear cells (PBMC) of patients with multiple myeloma and analyse it's clinical significance.Methods Thirty patients with multiple myeloma in the Department of Hematopathy,the Third Affiliated Hospital of Xinxiang Medical University from January 2016 to January 2017 were selected as observation group;and thirty healthy donors whose gender and age machted with patients in the observation group were selected as control group.Peripheral blood mononuclear cells were obtained from subjects in observation group and control group by using the method of density gradient centrifugation.The content of IL-17 in supernatant of PBMC culture solution of subjects in the two groups was detected by enzyme linked immunosorbent assay and the expression of IL-17 mRNA in PBMC was detected by quantitative real-time polymerase chain reaction;the cellular morphology of PBMC of subjects in control group was observed by scanning electron microscope after co-culturing with the serum of patients in observation group.Results The content of IL-17 in supernatant of PBMC culture solution of subjects in the observation group and control group was (30.79 ± 4.96),(10.10 ± 4.15) ng · L-1 respectively;the content of IL-17 in supernatant of PBMC culture solution of subjects in the observation group was significantly higher than that in the control group (t =3.412,P ＜ 0.05).The expression of IL-17 mRNA in PBMC in the observation group and control group was 4.28 ± 1.34 and 2.45 ±0.95 respectively;the expression of IL-17 mRNA in PBMC in the observation was significantly higher than that in the control group (t =2.796,P ＜0.05).After co-culturing of PBMC of subjects in the control group with the serum of patients in the observation group,the morphology of PBMC changed obviously,and membrane desquamate,membrane disintegration,even membranolysis were observed in some cells with the prolongation of co-culture time.Conclusion The over-expression of IL-17 in PBMC of patients with multiple myeloma may play a certain role in the occurrence and development of this disease.
ABSTRACT
<p><b>OBJECTIVE</b>To study the value of serum Cystatin C (Cyst C) in the evaluation of glomerular filtration function in children with viral encephalitis.</p><p><b>METHODS</b>Serum levels of Cyst C, urea nitrogen (BUN) and creatinine (Cr) were measured in 92 children with viral encephalitis and in 50 healthy children as a control group. According to glomerular filtration rate (GFR), the encephalitis group was subdivided into normal renal function, renal insufficiency in the compensatory or decompensatory stage, and renal failure /end-stage groups.</p><p><b>RESULTS</b>Serum levels of Cyst C, BUN and Cr in the encephalitis group increased and GFR decreased significantly compared with those in the control group (P<0.01). With the decline of renal function, GFR decreased and serum levels of Cyst C, BUN and Cr increased gradually. Serum levels of Cyst C and GFR were significantly different among the encephaitis subgroups (P<0.01). For serum levels of BUN and Cr, there were significant differences among the subgroups except between the normal renal function and the compensatory renal insufficiency groups. Serum Cyst C level was positively correlated with serum BUN and Cr levels, and negatively correlated with GFR.</p><p><b>CONCLUSIONS</b>The children with viral encephalitis have different degrees of renal impairments. Cyst C appears to be superior to BUN and Cr as a marker for the evaluation of glomerular filtration function. Measurement of serum Cyst C levels is very valuable in renal function monitoring in children with viral encephalitis.</p>

Objective To observe the curative effect and recurrence rate of desmopressin acetate(DDAVP) combined with bladder training therapy on primary nocturnal enuresis(PNE) in chlidren.Methods One hundred children with PNE were randomly divided into control group and observation group(50 cases in each group).Children in control group were treated with simple DDAVP,and patients in observation group were treated with bladder training while DDAVP was using.The course of treatment were 3 months.The therapeutic effect between the 2 groups when the treatment was finished was compared and then followed up all the cases for 3 months to compare the near-term and long-term recurrence rate between the 2 groups.SPSS 13.0 software was used to analyze the data.Results The total effective rate in control group was 72.9%,and the near-term recurrence rate and the long-term recurrence rate were 22.9% and 54.3%,respectively.The total effective rate in observation group was 91.3%,and the near-term recurrence rate and the long-term recurrence rate were 11.9% and 28.6%,respectively.The total effective rate was significantly higher in observation group than that in control group(Z=-1.972,P=0.049).The near-term recurrence rate in 2 groups had no significant difference(?2=1.632,P=0.201).The long-term recurrence rate was extremely lower in observation group than that in control group(?2=5.249,P=0.022).Conclusions There is significant curative effect that DDAVP combined with bladder training therapy on PNE in children,and it can lower the long-term recurrence rate.
