摘 要:目的探究朱红膏对脂多糖( lipopolysaccharide, LPS)刺激的人单核细胞系(human acute monocytic leukemia cell line,THP-1)分泌人白细胞介素-1p( interleukin-1 beta,IL-1β)、人可溶性细胞间黏附分子-1 (soluble intercellular adhesion molecule-1,sICAM-1)、人白细胞介素-8(interleukin-8,IL-8)和人单核细胞趋化蛋白-1( monocyte chemoattractant protein-1, MCP-1 )的影响,探讨其促进皮肤创伤愈合的机制。方法用细胞计数试剂盒(cellcountingkit-8,CCK-8)检测朱红膏对THP-1细胞活力的影响,用酶联免疫吸附法检测朱红膏对LPS刺激的THP-1表达IL-1β、sICAM-1、IL-8和MCP-1的影响。结果朱红膏和LPS共同作用THP-1细胞24h后,朱红膏在汞含量4.2-8.4mg/kg时可抑制THP-1细胞表达MCP-1(P〈0.01,P〈0.05);在汞含量2.1mg/kg时可抑制THP-1细胞分泌IL-1β(P〈0.05);在汞含量2.1-8.4mg/kg时可抑制IL-8的分泌(P〈0.01,P〈0.05),而对分泌sICAM-1的影响差异无统计学意义。结论朱红膏通过降低LPS诱导的THP-1表达IL-1β、IL-8和MCP-1,从而抑制过度的炎性反应来促进慢性创面愈合。Objective To observe the effects of Zhuhonggao (ZHG) on the expression of interleukin 1 beta (IL-1β), soluble intercellular adhesion molecule-1 ( sICAM-1 ), interleukin-8 ( IL-8 ) and monocyte chemoattractant protein-1 ( MCP-1 ) induced by lipopolysaccharide(LPS) in THP-1 cells, and study the mechanisms of ZHG on promoting skin wound healing. Methods THP-1 cell activity was observed by Cell Counting Kit-8( CCK-8 ) after treating with ZHG. The expression of IL-1β, sICAM-1, IL-8 and MCP-1 were measured by enzyme linked immunosorbent assay (Elisa). Results After treating with ZHG and LPS for 24 h, ZHG decreased the expression of MCP-1 ( content of mercury, Hg 4.2 - 8.4 mg/kg) (P〈0.01, P〈0.05 ), decreased the expression of IL-1β ( Fig 2.1 mg/ kg) (P〈0.05) and IL-8 (Hg 2.1 - 8.4 mg/kg) (P〈0.01, P〈0. 05). ZHG had no significant effect on sICAM-1. Conclusion It is possible that ZHG inhibit the expression of IL-1β, IL-8 and MCP-1 on THP-1 cells, therefore may inhibit excessive inflammatory response.
