JJWT promotes antibacterial and anti-inflammatory activity for diabetic wound healing through the PI3K/akt signaling...

Management of wound infection and inflammation in diabetic foot is crucial for its treatment. Jiangjunsan has demonstrated potential anti-inflammatory properties and the ability to promote wound healing. This work aimed to investigate the effects of Jiangjunsan wrapping therapy (JJWT) on microbial colonies, levels of inflammatory factors, and regulation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway (SPW) in diabetic foot wounds.

Sixty diabetic foot patients were enrolled into a control group (CG) and a treatment group (TG), with 30 patients in each group. CG received topical magnesium sulfate in addition to standard treatment, while TG received JJWT for two weeks. The quantity of wound microbial colonies and levels of tumor necrosis factor (TNF)-α and interleukin (IL)-6 were measured before and after treatment, and Western blot analysis was utilized to assess expression levels of PI3K and AKT in wound tissues.

After treatment, TG exhibited a significantly lower microbial colony count than CG (P < 0.05). Both groups showed a great decrease in TNF-α and IL-6 levels post-treatment (P < 0.05), with TG demonstrating lower levels of TNF-α, IL-6, PI3K, and AKT proteins relative to CG (P < 0.05).

JJWT effectively reduced microbial colony counts in diabetic foot patients, markedly suppressed the expression of TNF-α and IL-6, and enhanced wound healing by modulating PI3K/Akt SPW, indicating strong antibacterial and anti-inflammatory properties of Jiangjunsan.
