    ABSTRACT: To explore the effects of Yiqi Huayu Recipe, a compound traditional Chinese herbal medicine for replenishing qi and resolving stagnation, on transforming growth factor-beta1(TGF-beta1) of skin ulcers in rats with diabetes. Sixty rats were randomly divided into six groups, Yiqi Huayu Recipe-treated group, Yiqi (replenishing qi) Recipe-treated group, Huayu (resolving stagnation) Recipe-treated group, basic fibroblast growth factor (bFGF) treated group, untreated group and normal control group. Diabetes was induced by peritoneal injection of streptozotocin and skin ulcers were made by surgery method in rats except for the normal control group. Then the rats were administered with different drugs respectively, and the expression of TGF-beta1 in granulation tissue of the skin ulcers was detected with the methods of Western blotting, image analysis and immunohistochemistry. The level of TGF-beta1 expression in the untreated group was lower than that in the normal control group (P<0.01); and the level of TGF-beta1 expression in the drug-treated groups was higher than that in the untreated group (P<0.01); and the TGF-beta1 expression in the Yiqi Huayu Recipe-treated group was higher than that in the Yiqi Recipe-treated group, Huayu Recipe-treated group and bFGF-treated group (P<0.05). The replenishing qi and resolving stagnation therapy can control the secretion of TGF-beta1 of the wound in the process of wound healing in the levels of gene and molecule.

    ABSTRACT: To explore the effects of reinforcing qi and nourishing blood recipes on vascular endothelial growth factor (VEGF) and the microvessel count (MVC)in granulation tissue in rats with chronic skin ulcers. A total of 90 male SD rats with back full-thickness skin lesion were used in this study. Except for the normal control group, the rats were injected with hydrocortisone for inducing chronic skin ulcers, and were randomly divided into untreated group, Sijunzi Decoction group, Siwu Decoction group and Bazhen Decoction group. The time of wound healing was observed; immunohistochemical method and image analytical method were used to test the expressions of VEGF and MVC in granulation tissue of dermal chronic ulcers in the rats. In the untreated group, the time of wound healing was significantly longer than that in the normal group (P<0.01). The time of wound healing was obviously shortened in the three treated groups as compared with the untreated group (P<0.01, P<0.05). In the Sijunzi Decoction group, the time of wound healing was obviously shorter than those in Siwu Decoction group and Bazhen Decoction group (P<0.05, P<0.01). In the untreated group, the expression of VEGF and MVC were significantly lower than those in the normal control group (P<0.01). The expression of VEGF and MVC were obviously increased in the three treated groups as compared with those in the untreated group (P<0.01, P<0.05). In the Sijunzi Decoction group, the expression of VEGF and MVC were obviously lower than those in Siwu Decoction group and Bazhen Decoction group (P<0.05, P<0.01). Reinforcing qi and nourishing blood recipes can promote wound healing in rats through up-regulating the expression of VEGF in granulation tissue of dermal chronic ulcers, and inducing angiogenesis.
