炎症反应是临床常见的一个病理过程,是机体对于刺激的一种防御性反应. 根据炎症的发生是否与细菌感染有关可分为感染性炎症和无菌性炎症两大类. 无论在感染性炎症还是在无菌性炎症,炎症反应的一个重要特征都是中性粒细胞的迁徙和聚集. 中性粒细胞作为炎症反应的一线细胞,在感染性炎症中对于抵御入侵的病原体非常重要,而在无菌性炎症中对于组织和伤口的修复愈合同样重要,是炎症反应的核心因素,其功能对于人体生命至关重要.“,”Inflammation is a common clinical pathological process,is a defensive reaction of the body to stimulation.According to inflammation with or without bacterial infection,inflammation can be divided into two categories,infectious and aseptic inflammation.Neutrophil migration and aggregation is an important fea-ture of inflammation.Neutrophil is the first line in the inflammatory reaction.In the infectious inflammation, it is very important against invading pathogens,and in aseptic inflammation it is important for wound healing and tissue repair,which is essential factor of inflammation,playing a vital role for human life.
