Objective: To observe the clinical efficacy of Yunnan Baiyao and Dracon Blood on the wound which is hard to heal after the operation of mixed hemorrhoid and investigate its effects on the levels of matrix metalloproteinases-3 (MMP-3)
tissue inhibitor of metalloproteinase-1 (TIMP-1)
vascular endothelial growth factor (VEGF) and transforming growth factor-β1 (TGF-β1). Method: One hundred and sixteen patients were randomly divided into control group (58 cases) and observation group (58 cases) by random number table. After debridement and disinfection
patients in control groups got Shengji Yuhong paste
and in observation group
Yunnan Baiyao and Dracon Blood was applied on the wound
1-2 times/days. Both groups got the treatment for continuous 14 days. The recovery situation of wound was compared between two groups; histomorphology of the wound was observed
and levels of MMP-3
TIMP-1
VEGF and TGF-β1 were detected before and after treatment. Result: The total effective rate of disease in was 94.83% in observation group
higher than 81.03% in control group (χ2=5.198
P<0.05). At the 7th day after treatment
scores of wound area
granulation tissue of wound
edema degree and wound exudate in observation group were lower than those in control group (P<0.01). At the 14th day after treatment
scores of wound area and granulation tissue of wound were lower than those in control group (P<0.01). Wound healing time in observation group was (10.75±3.64)days
shorter than (14.85±5.73) days in control group (P<0.01). At the 7th day after treatment
number of fibroblasts
number of new capillaries and wound macrophage ratio in observation group were higher than those in control group (P<0.01). At the 14th day after treatment
number of fibroblasts
number of new capillaries and wound macrophage ratio were lower than those at the 7th day after treatment in both groups
and these three indexes in observation group were lower than those in control group (P<0.01). Levels of MMP-3
VEGF and TGF-β1 in observation group were higher and level of TIMP-1 was lower than those in control group (P<0.01). Conclusion: Yunnan Baiyao and Dracon Blood can promote the recovery of wound
shorten the healing time
change histomorphology of wound and regulate levels of VEGF
TGF-β1 and MMP-3/TIMP-1 to promote the formation of capillary vessels in wound surface
the growth of granulation tissue and repair of epidermis.
