[Advances in the research of influence of pH value on healing of chronic wounds].

Chronic wounds are with characteristics of long last time and cannot heal in time, which is a problem in clinic. Wound pH value plays an important role in the process of healing of chronic wounds. In this paper, we review the relative researches on wound pH value and wound microenvironment, summarize the potential relationship between wound pH value and healing of chronic wounds, as well as the method to change pH value of chronic wounds, thereby to provide theoretical basis for the treatment of chronic wounds in clinic.慢性创面具有持续时间长、无法及时愈合的特点，是临床工作的一个难题。在慢性创面愈合过程中，创面pH值扮演着重要的角色。本文就创面pH值与创面微环境相关研究进行梳理，总结创面pH值与慢性创面愈合之间的潜在关系及改变慢性创面pH值的方法，以期为临床慢性创面的治疗提供理论依据。.
