The platelet-rich plasma (PRP) has been advocated as a way to introduce increased concentrations of growth factors and other bioactive molecules to injured tissues in an attempt to optimize the local healing environment. A 94-yr-old woman with various comorbidities presented with a two-week history of severe cutaneous ulcer on the left dorsum of foot. It was caused by recurrent mechanical trauma and did not respond to several wound debridement and simple dressings. However, after she was completed on seven times of autologous PRP treatments, we observed complete healing of the skin lesion within 3 months. Herein, we report a case of recalcitrant cutaneous ulcer with various comorbidities and discuss about the promising possibility of autologous PRP as an effective alternative therapeutic modality.

OBJECTIVETo evaluate the therapeutic effects of VSD combined with irrigation of oxygen loaded fluid on chronic wounds in diabetic patients.
METHODSTwenty-six diabetic patients hospitalized in Nanfang Hospital of Southern Medical University from September 2010 to June 2013, with chronic ulcers on lower extremities conforming to the inclusive criteria, were divided into group VSD (n = 8), VSD + irrigation control group (VSD + IC, n = 9), VSD + oxygen loaded fluid irrigation group (VSD OLI, n = 9) according to the random number table. After gross observation was conducted and wound secretion was sent for bacterial culturing right after admission, debridement was performed. During the debridement, granulation tissue of wound center was harvested for determination of the activity of lactate dehydrogenase (LDH) and succinate dehydrogenase (SDH) with ELISA. After debridement, the patients in group VSD were treated with VSD (negative pressure from -30 to -25 kPa, the same below); the patients in group VSD + IC were treated with VSD combining irrigation of normal saline; the patients in group VSD + OLI were treated with VSD combining normal saline loaded with oxygen (flow of 1 L/min ) irrigation. Drainage tube blockage was recorded and its incidence rate was recorded during the treatment. On post treatment day (PTD) 7, tissue exudates were collected and analyzed with blood gas analyzer for determining the partial pressure of oxygen of the exudate. After the VSD was terminated, bacterial culture was conducted as before, and the bacterial clearance rate was calculated. After the calculation of granulation tissue coverage rate, the granulation tissue in the center of the wound was harvested for histopathological observation with HE staining; morphological characteristics and density of mitochondria were observed with transmission electron microscopy; the activity of LDH and SDH was estimated as before; microvascular density (MVD) was counted after CD31 antibody immunohistochemical staining. Then the second stage operation was performed. The method of second stage operation was recorded and survival rate of grafted skin or flap was calculated. Data were processed with one-way analysis of variance, LSD- t test, rank sum test, or Fisher's exact test.
RESULTS(1) The gross observation showed that before debridement there was only necrotic tissue without granulation tissue in the wounds of patients in all the 3 groups. On PTD 7, granulation tissue was found in the wounds of patients in all the 3 groups. HE staining showed that there were more abundant newborn microvessels and regularly arranged fibroblasts in the wounds of group VSD + OLI; less newborn microvessels and relatively sparsely fibroblasts were observed in the wounds of group VSD + IC. There were only sparse newborn microvessels and fibroblasts in the wounds of group VSD. (2) Rates of drainage tube blockage, granulation tissue coverage, and bacterial clearance showed significant differences among the 3 groups (with F values from 10.98 to 770.24, P values below 0.01). The drainage tube blockage rate was significantly lower in groups VSD + IC and VSD + OLI [(2.0 ± 0.4)% and (1.9 ± 0.6)%] than in group VSD [(16.0 ± 1.3)%, with t values respectively 28.77 and 29.20, P values below 0.01]. (3) On PTD 7, the partial pressure values of oxygen of the exudate in groups VSD + IC, VSD + OLI, and VSD were respectively (111 ± 4), (43 ± 4), and (40 ± 4) mmHg (1 mmHg = 0.133 kPa, F = 882.76, P < 0.01). (4) The density of mitochondria in group VSD + OLI was obviously higher than that of the other 2 groups, full in shape, with complete outer membrane and no vacuolization. (5) During debridement, the activity of LDH and SDH in 3 groups showed no significant differences (with F values respectively 0.08 and 1.03, P values above 0.05). On PTD 7, the activity of LDH was lower in group VSD + OLI [(103 ± 15) U/L] than in group VSD + IC [(136 ± 16) U/L, t = 4.49, P < 0.01], while it was higher in group VSD [(155 ± 16) U/L] than in group VSD + IC (t = 2.47, P < 0.05). The activity of SDH was higher in group VSD + OLI [(2.93 ± 0.27) U/L] than that in group VSD + IC [(1.77 ± 0.22) U/L] or group VSD [(1.61 ± 0.19) U/L, with t values respectively 10.21 and 11.65, P values below 0.01]. (6) On PTD 7, there was more positive expression of CD31 in group VSD + OLI than in the other 2 groups. The MVD of groups VSD, VSD + IC, and VSD + OLI were respectively (109 ± 5), (124 ± 5), (141 ± 6) per 400 times visual field (F = 68.78, P < 0.01). (7) The patients in 3 groups mainly received skin or flap grafting as the second stage operation. The survival rates of skin and flap in group VSD + OLI were higher than those of groups VSD + IC and VSD (with t values from 3.32 to 8.26, P < 0.05 or P < 0.01), and the rates were higher in group VSD + IC than in group VSD (with t values respectively 2.67 and 3.18, P values below 0.05).
CONCLUSIONSVSD + OLI is effective in reducing drainage tube blockage, removing necrotic tissue and bacteria, ameliorating ischemia and hypoxia of wound tissue, providing fresh wound bed for wound healing, and improving skin or flap graft survival rates.

OBJECTIVETo study the role and mechanism of the Yi medicine, Yi Bu A Jie () extract, in topical treatment of diabetic skin ulcers, with a view to finding a breakthrough natural drug for the prevention and treatment of diabetic skin ulcers.
METHODSA model of diabetic skin ulcers in Kunming mice was developed. Yi Bu A Jie was extracted in a Soxhlet extractor. Two different concentrations of the extract (0.005 mg/mL and 0.01 mg/mL) were applied to the wound of diabetic skin ulcers once every 3 days, and local skin appearance and histopathological changes were observed.
RESULTSThe shortest healing time was 25.25±2.06 day with a low concentration (P=0.0037 compared with the high concentration group, 33.14±2.21 day; P=0.0082 compared with control group, 28.21±2.14 days). The longest healing time was in the high concentration group (P=0.0025 compared with the control group). In both groups, a large number of inflammatory neutrophil cells were exuded during the experimental period. In the low concentration group, capillary-rich granulation tissue and actively growing fibroblasts appeared in the wound, while there was much necrotic tissue in the high concentration group.
CONCLUSIONYi Bu A Jie extract has an inhibitory effect on diabetic skin ulcers in mice, and the low concentration is more suitable.

OBJECTIVETo observe the clinical efficacy of Chinese medicine (CM) treatment of Hongyou Ointment and Shengji Powder on diabetic ulcers, and to observe the influence of CM treatment on the expressions of proteins associated with the Wnt signaling pathway, such as β-catenin, c-myc and K6.
METHODSsixty-two patients fitting the registration standards were randomly divided into the CM group (31 patients) and the Western medicine (WM) group (31 patients) by a random number table. The patients in the CM group were treated with Hongyou Ointment and Shengji Powder externally. The patients in the WM group were treated with mupirocin ointment, growth factor (bFGF), and Vaseline gauze for external use and with basic therapies. Wound-healing time and four-week healing rate were recorded. The wounds were measured by digital photography and ImageJ software. Skin biopsies were obtained from 24 patients before CM treatment and 20 patients after CM treatment. Immunohistochemical tests and semi-quantitative imaging with NIH ImageJ 1.42 software were used to analyze the changes in protein expression of β-catenin, c-myc, and K6.
RESULTSFifty-three patients completed the trial; four patients in the CM treatment group and five patients in the WM group dropped out. Among them, four were dissatisfied with the treatment process, two could not continue because of their jobs, two failed to complete the course of follow-up appointments, and one was diagnosed with squamous cell carcinoma during treatment. The comparison of ulcer healing rates between the two groups showed insignificant differences (P=0.77). The ulcer healing rates were 33.33% (9/27) in the CM group and 26.92% (7/26) in the WM group. However, the effective rate was significantly higher in the CM group (81.48%, 22/27) than in the WM group (57.69%, 15/26, P=0.04). The mean wound healing time was shorter in the CM group (22.71 ±5.46 days) than in the WM group (26.56 ±7.56 days, P=0.04). CM treatment was well tolerated, and there was no withdrawal due to adverse reactions. Immunohistochemical analysis in the refractory wound indicated higher expressions of β-catenin, c-myc and K6 compared with the normal skin. β-catenin was abnormally expressed in the nuclei of the keratinocytes and fibroblasts at the wound margins, and the expressions of c-myc and K6 were highly expressed in the full hyperplastic epidermis, especially in the granular layer (P<0.05). The expressions of these proteins decreased after CM treatment. The expression levels of β-catenin, c-myc, and K6 proteins before and after the treatment were 101.88 ± 10.76 vs. 140.42 ±8.45; 113.27 ± 16.75 vs. 153.79 ±8.32; 90.39 ±11.07 vs. 151.29 ±7.39, respectively.
CONCLUSIONSCM treatment using Hongyou Ointment and Shengji Powder was efficient in the management of diabetic skin ulcers. The mechanism of action might be related to the inhibition of the Wnt signaling pathway.

The aim of this study was to evaluate the efficacy of Bletilla striata polysaccharide on diabetes mellitus ulcers. Diabetes mellitus animal model was established by single ip injection of streptozotocin (STZ, 50 mg x kg(-1)) with the criteria of blood glucose > or = 16.7 mmol x L(-1) after 72 h. 4 weeks after STZ injection, each animal received two full thickness incisional wounds (1.8 cm in diameter). The wounds then were divided into B. striata polysaccharide group and PBS group. Wound closure rate, fibroblast (FB) infiltration, hydroxyproline (OHP) content and myeloperoxidase (MPO) levels were examined on day 3, 7, 14, 21 post wound. The treatment of B. striata polysaccharide significantly facilitated diabetes mellitus ulcers healing compared to PBS group. Histological analysis showed that B. striata polysaccharide markedly increased inflammatory cell infiltration in wound area. The herb also strongly evaluation of FB, OHP demonstrated a significantly increased in B. striata polysaccharide group. B. striata polysaccharide group promoted wound closure by means of enhanced inflammatory cell infiltration and re-epithelialization, and the promotion of FB and OHP levels.
