BACKGROUND:Platelet-derived growth factor has the ability of wound repair, and relevant studies mainly focus on bone tissue repair. However, there are less studies about the effect of platelet-derived growth factors in skin wound healing. OBJECTIVE:To investigate the role of platelet-derived growth factor to promote wound healing by the regulation of bone marrow mesenchymal stem cels to the wound. METHODS:Bone marrow mesenchymal stem cels from rats were cultured. Immunofluorescence method was conducted to detect cel surface markers of CD34 and CD44 in bone marrow mesenchymal stem cels. Thirty healthy male SD rats were divided into five groups at random. Bone marrow mesenchymal stem cels labeled with PKH-26 were injected into the rat caudal vein in each group. The rats were anesthetized 1 week after injection. On the center of rat back, a 3-cm incision was made to establish a wound healing model. Different concentrations of platelet-derived growth factor were injectedvia multi-points on the skin wound after modeling, and the control group was treated with the same volume of normal saline. Skin wound tissues were taken for relevant parameter measurement at 14 days after injection. RESULTS AND CONCLUSION: Under the fluorescence microscope, platelet-derived growth factor could induce the migration and accumulation of bone marrow mesenchymal stem cels to the trauma in a dose-dependent manner and promote the wound healing. Masson staining showed that, with the concentration increase, platelet-derived growth factors could reduce inflammatory cel infiltration and increase the number of colagen fibers. Results from western blot assay showed that platelet-derived growth factor could inhibit the expression of matrix metaloproteinase-1, promote the expression of tissue inhibitor of matrix metaloproteinase 1 in the wound, and inhibit the colagen degradation, thereby promoting skin wound healing indirectly.

Objective:To improve the quality standard for Kangshiming mixtures. Methods:The identification of Angelicae Sinen-sis Radix, Astragali Radix and Phellodendri Chinensis Cortex was carried out by TLC. The contents of puerarin and paeoniflorin in the preparations were determined by HPLC. Results:The spots displayed in TLC were clear without interference from the negative control. The linear range for puerarin was 1. 64-49. 20μg·ml-1(r=0. 999 9) and 4. 22-63. 30μg·ml-1(r=0. 999 6) for paeoniflorin. The average recovery was 99. 63%(RSD=2. 14%,n=9) and 99. 05%(RSD=2. 70%,n=9) for puerarin and paeoniflorin, respectively. Conclusion:The method is accurate, reliable and specific, and can be used in the quality control of Kangshiming mixtures.

OBJECTIVETo detect the expression level of interleukin 17 (IL-17) in the plasma and colonic mucosa of patients with ulcerative colitis (UC), and to explore the synergistic mechanism of qingchang huashi recipe (QHR) combined with Mesalazine.

METHODSRecruited were 24 mild or moderate UC patients of damp-heat inner accumulation syndrome (DHIAS). Their samples of intestinal tissues were histologically graded. They were assigned to the combination group and the Western medicine (WM) group, 12 in each group. Besides, another 12 healthy volunteers were recruited as the healthy control group. QHR combined Mesalazine were given to patients in the combination group, while those in the WM group took Mesalazine. The therapeutic course for all was 3 months. By the end of treatment the expression level of IL-17 in the plasma and colonic mucosa was detected using ELISA. The infiltration of IL-17 in the intestinal mucosal tissue was detected by immunohistochemical SP method.

RESULTSThe expression level of IL-17 in the plasma and colonic mucosa was significantly higher in UC patients than in healthy controls (P <0. 05). The higher the histological grading the higher the expression level. The expression level of IL-17 in plasma and colonic tissues decreased after treatment in the two treatment groups (P < 0.05). Besides, the expression level of IL-17 was lower in the combination group than in the WM group (P <0.05).

CONCLUSIONQHR combined Mesalazine could synergically enhance the effect and effectively inhibit intestinal inflammation through down-regulating the expression of IL-17.
