Effect of Golden Wanhong Ointment on wound microbiota in patients with diabetic foot ulcer.

TL;DR

Golden Wanhong Ointment promoted wound healing in diabetic foot ulcer patients by significantly remodeling wound microbiota structure, reducing pathogenic bacteria abundance, and decreasing local inflammatory markers.

Key Findings

Treatment with Golden Wanhong Ointment significantly reduced wound area, pain scores, and inflammatory markers in DFU patients.

  • 31 DFU patients were enrolled with wound secretion samples collected before and after treatment (62 samples total)
  • Wound area, pain score (VAS), and inflammatory factors IL-6 and TNF-α were all significantly reduced post-treatment
  • All clinical outcome improvements reached statistical significance at P<0.001
  • Measurements were taken as paired pre- and post-treatment assessments within the same patients

16S rRNA gene sequencing yielded high-quality microbial sequence data from DFU wound samples.

  • Sequencing targeted the V3-V4 region of the 16S rRNA gene using amplicon sequencing
  • Total of 4,579,390 high-quality Clean Reads were generated across all 62 samples
  • Average of 73,861 high-quality reads per sample
  • 62 wound secretion samples were collected from 31 patients (one sample per patient pre- and post-treatment)

Golden Wanhong Ointment treatment caused significant compositional remodeling of wound microbiota at the phylum level.

  • Relative abundance of Proteobacteria decreased following treatment
  • Relative abundance of Firmicutes increased following treatment
  • Changes were described as a 'significant compositional remodeling of wound microbiota structure after treatment'
  • Analysis was conducted using 16S rRNA amplicon sequencing comparing pre- and post-treatment samples

At the genus level, abundances of infection-associated bacteria Prevotella and Escherichia-Shigella were significantly reduced after treatment.

  • Prevotella, closely associated with infection, showed significantly reduced relative abundance post-treatment
  • Escherichia-Shigella, closely associated with infection, also showed significantly reduced relative abundance post-treatment
  • These genera were specifically identified as 'key pathogenic bacteria' in the wound microenvironment
  • Reduction in these genera was proposed as a mechanism by which the ointment reduces local inflammatory response

The authors propose that Golden Wanhong Ointment promotes wound healing through microbiota regulation, linking its modern microbiological effects to its traditional Chinese medicine functions.

  • Traditional functions of the ointment are described as 'clearing heat and detoxifying, removing necrotic tissue and promoting granulation'
  • The study provides 'a modern scientific interpretation of its traditional effects from a microbiological perspective'
  • The proposed mechanism includes inhibiting pathogenic bacteria abundance, reducing local inflammatory response, and improving the wound microenvironment
  • Golden Wanhong Ointment is described as a 'hospital preparation,' indicating it is a locally compounded traditional medicine formulation

What This Means

This research suggests that Golden Wanhong Ointment, a traditional Chinese medicine preparation used in hospitals, can beneficially change the community of bacteria living in diabetic foot ulcers (DFU). The study enrolled 31 patients with diabetic foot ulcers and collected wound samples before and after treatment. Using modern DNA sequencing technology to identify bacteria in the wounds, researchers found that after treatment, harmful bacteria—particularly Prevotella and Escherichia-Shigella—became less abundant, while the overall balance of bacterial communities shifted. At the same time, wound size decreased, pain scores improved, and levels of inflammatory proteins (IL-6 and TNF-α) in the wounds dropped significantly, all with strong statistical confidence (P<0.001). This research matters because diabetic foot ulcers are serious, difficult-to-treat wounds that are a leading cause of amputation worldwide. Bacterial infection plays a major role in preventing these wounds from healing. The finding that a traditional herbal ointment can reshape the wound's microbial community—reducing the bacteria most associated with infection and inflammation—offers a potential biological explanation for why this remedy has been used traditionally. It bridges ancient medical knowledge with modern microbiological science. This research suggests that microbiota regulation may be one mechanism through which Golden Wanhong Ointment supports wound healing, providing scientific grounding for its traditional descriptions of 'clearing heat and detoxifying.' However, the study was relatively small (31 patients) and did not include a control group for comparison, so further research with larger, controlled trials would be needed to confirm these findings and establish the ointment's effectiveness more definitively.
