过敏性紫癜患儿血浆可溶性CD146与可溶性血管细胞黏附分子-1检测的意义

目的 探讨可溶性CD146(sCD146)与可溶性血管细胞黏附分子-1(sVCAM-1)在过敏性紫癜(HSP)患儿血浆中的表达水平及临床意义.方法 采用ELISA法检测HSP患儿(急性期42例、缓解期39例)及健康对照组儿童(30例)外周血浆sCD146、sVCAM-1水平,比较HSP患儿急性期、缓解期和健康对照组之间的差异以及急性期肾脏受累组、无肾脏受累组之间的差异,并对HSP患儿急性期血浆sCD146与sVCAM-1水平进行相关性分析.应用SPSS 13.0软件进行统计学处理.结果 HSP患儿急性期sCD146、sVCAM-1水平明显高于缓解期和健康对照组,差异均有统计学意义(Pa＜0.01)；缓解期sCD146水平仍高于健康对照组,差异有统计学意义(P＜0.01),缓解期sVCAM-1水平与健康对照组比较差异无统计学意义(P＞0.05)；急性期肾脏受累组sCD146、sVCAM-1水平高于无肾脏受累组,差异均有统计学意义(Pa＜0.01)；HSP患儿急性期血浆sCD146与sVCAM-1水平呈正相关(r=0.79,P＜0.01).结论 sCD146与sVCAM-1在HSP和紫癜性肾炎的发生发展中起重要作用.动态监测HSP患儿血浆sCD146、sVCAM-1水平对于判定其病情发展及预后有一定意义.

Significance of Detection of Plasma Soluble CD_(146) and Soluble Vascular Cell Adhesion Molecule-1 in Children with Henoch-Schonlein Purpura

Objective To study the expressions and clinical significance of plasma soluble CD146(sCD146) and soluble vascular cell adhesion molecule-1(sVCAM-1) in children with Henoch-Schonlein purpura(HSP). Methods Forty-two children with HSP in the acute phase and 39 children with HSP in the remission phase were enrolled in this study,and 30 healthy children served as control group.The levels of plasma sCD146 and sVCAM-1 were detected by enzyme-linked immunosorbent assay(ELISA),and the differences of the levels of pl...
