Abstract
Objective To evaluate the effects of Chuanglingye decoction on angiogenesis and wound healing. Methods With a series of dosages of Chuanglingye decoction, their optimal effects of angiogenesis were searched for through the chicken embryo allantois membrane model（CAM）. The vascular endothelial cell proliferation experiment （MTT） and the migration assay were used for the detection of effects. The gauze loading with Chuanglingye decoction of 0.2 ml as the experimental group and with saline of 0.2ml as the control group were applied on the total skin mechanical round wound of 1.5cm diameter and changed every other day. The sizes of area were detected on the day of 0,3,7,14 and 28 as well as the scores of inflammatory response, contains of TNF-αand Il-6 were detected on the day of 3 and 7. Results The CAM experiments showed that the angiogenic effects of 0.2 ml and 0.3 ml dosage of the Chuanglingye group were significantly lower than those of the control group（P〈0.05）. The 0.2 ml dosage of Chuanglingye decoction was chosen for the further experiment. The HUVEC proliferation rate of the experimental group decreased 21%, as compared with the results of control group. The cell migration movement of 12 hours, 24 hours in the experimental group were significantly lower than those in the control group. For theanimal experiments, the area sizes of the wound were＆nbsp;similar in the experimental and control group without any significant differences. The scores of inflammatory response and contains of TNF-α（768±107）ng/L,（380±47）ng/L and Il-6（664±133）ng/L,（363±43）ng/L in the experimental group were significant decreased than those of the control group on the day of 3（958± 140）ng/L,（2215±314）ng/Land 7（512±62）ng/L,（1562±174）ng/L. Conclusion It showed that Chuanglingye decoction had negative effects on vascular endothelial cell migration and proliferation and thus inhibiting angiogenesis. These effects did not infer the process of the wound healing due to its ameliorating the inflammatory response which may be a help to wound healing.
