Objective:To explore the adjustment factors to the migration and functional activity on macrophages in the uterine of inflammatory mice induced by LPS.Methods:150 Kunming female mouse were divided into control group (group A),LPS model group (group B),MCP-1 blocking-up group (group C),the mice uterines were extracted separately at hour 1,3,6,12,24.The number of CD14+ macrophages and the expression of CD14 macrophages were detected by Immunohistochemistry,ELISA detects the expression of TNF-α and MCP-1.Results:①Compared with group A,the number of CD14+ macrophages and the expression of CD14 in endometrium,myometrium,perimrtrium of group B were highly significantly increased (P<0.01) at every time points,the endometrium,myometrium of group C were closely to normal level at 1,3,6 h;compared with group B,the number of CD14+ macrophages and the expression of CD14 were highly significantly decreased(P<0.01)at 1,3,6 h of perimrtrium of group C and every time points of endometrium,myometrium of group C.②Compared with group A,the content of TNF-α and MCP-1 were highly significantly increased (P<0.01) at every time points of group B and 12,24 h of group C;compared with group B,the content of TNF-α and MCP-1 of group C were highly significantly decreased(P<0.01) at every time points.Conclusion:The migration of macrophages and the expression of CD14 and TNF-α in the uterine of inflammatory mice induced by LPS were regulated by MCP-1.%目的:探讨LPS诱导的炎症小鼠子宫巨噬细胞迁移和功能活性的调节因素.方法:将150只雌性昆明种小鼠随机分为对照组(A组)、LPS模型组(B组)、MCP-1阻断组(C组),于末次注射后的1、3、6、12、24 h取子宫.运用免疫组织化学方法检测CD14+巨噬细胞数量与CD14表达的变化,ELISA方法检测TNF-α、MCP-1的表达量.结果:①与 A 组相比,B 组内膜、肌层、外膜的CD14+巨噬细胞数目及CD14表达量在各时间点均极显著增加(P<0.01),C 组内膜和肌层在1、3、6 h时恢复至正常水平;与B组相比,C组外膜在1、3、6 h时以及C组的内膜和肌层在各时间点时CD14+巨噬细胞数目及CD14表达量均极显著减少(P<0.01).②与A组相比,B组在各时间点以及C组在12、24 h时TNF-α和MCP-1的含量极显著增多(P<0.01);与B组相比,C组各时间点的TNF-α和MCP-1的含量极显著减少(P<0.01).结论:LPS诱导的小鼠子宫炎症反应中巨噬细胞的迁移及CD14、TNF-α等关键分子的表达均受MCP-1的调节.
