Abstract
This study aimed to explore the effect and mechanism of Dragon's Blood on wound healing in patients with a pressure hand injury. A total of 120 patients with pressure hand injury treated in our hospital were randomly divided into two groups. Sixty patients in the control group were dressed with sterile gauze, and 60 patients in the observation group were smeared with blood exhaustion. The clinical effects and serological indexes of the two groups were compared, and the mechanism of wound healing was analyzed. The results showed that the treatment effective rate of the control group was 80% and that of the observation group was 93.33%. The treatment effective rate of the observation group was dramatically higher (P < 0.05). The number of patients with good granulation tissue in the observation group was 53, which was dramatically greater than that in the control group. The number of patients with a small amount of wound exudation was 51, which was dramatically greater than that in the control group (P < 0.05). After treatment, the levels of matrix metalloproteinase (MMP-3), vascular endothelial growth factor (VEGF), and transforming growth factor B1 (TGF-B1) in the observation group increased more dramatically (P < 0.05). The level of tissue inhibitor of metalloproteinase-1 (TIMP-1) decreased to 617.23 ng/L in the observation group, and the degree of reduction was more obvious (P < 0.05). Notably, Dragon's Blood promoted wound healing at the injury site by increasing the levels of MMP-3, VEGF, and TGF-B1and decreasing TIMP-1. The area of wound reduction in the observation group was 0.27 cm(2), and the reduction was more obvious (P < 0.05). The healing time of pressure hand injury in the observation group was 15.27 days, which was dramatically shorter (P < 0.05). In summary, Dragon's Blood had a good effect on the healing of the injured site in patients with pressure hand injury, which is worthy of promotion.
