ObjectiveTo systematically evaluate the potential effectiveness of JinHuang powder in the treatment of diabetic foot ulcers (DFUs). MethodsDatabases including PubMed, The Cochrane Library, Web of Science, CBM, WanFang data, VIP and CNKI were electronically searched from their inception to December 2013, to identify randomized controlled trials (RCTs) about JinHuang powder for DFUs. Two reviewers screened literature according to the inclusion and exclusion criteria, extracted data and assessed the methodological quality of included studies, and then meta-analysis was performed by using RevMan 5.1 software. ResultsA total of 3 RCTs involving 198 patients were included. The results of meta-analysis showed that:the JinHuang powder group were superior to the control group in total effective rate (RR=1.25, 95%CI 1.10 to 1.41, P=0.00) and the wound healing time (SMD=-3.32, 95%CI -5.69 to -0.96, P=0.00). ConclusionCurrent evidence suggests that the JinHuang powder is an effective therapeutic method for DFUs. Because of the limitations of quantity and quality of the eligible studies, large sample size studies are needed to validate the conclusion.
Objective To explore the effectiveness of microdissected thin thoracodorsal arterial perforator flap (TDAP) in repairing diabetic foot ulcers (DFUs). Methods The clinical data of 11 patients with DFUs admitted between March 2020 and February 2021 were retrospectively analyzed, including 5 males and 6 females, aged from 22 to 67 years, with an average of 49.3 years. There were 10 cases of type 2 diabetes and 1 case of type 1 diabetes; the duration of diabetes ranged from 3 months to 25 years (median, 8 months). The duration of DFUs ranged from 6 days to 120 months (median, 1 month). There were 6 cases of grade 3 and 5 cases of grade 4 according to Wagner classification. The tissue necrosis and purulent secretions were found in all ulcer wounds, as well as different degrees of tendon and bone exposure; skin defects ranged from 5 cm×3 cm to 17 cm×6 cm. The DFUs were repaired by microdissected thin TDAP, including 6 cases of flaps (including 1 case of lobulated flap), ranging from 10.0 cm×4.5 cm to 26.0 cm×7.0 cm; 5 cases of chimeric perforator flaps, the range of the flap was 10.0 cm×4.5 cm to 16.0 cm×5.5 cm, and the range of the muscle flap was 6 cm×2 cm to 10 cm×3 cm. The donor site was sutured directly. Results The operation time ranged from 3.42 to 11.17 hours, with an average of 5.92 hours. All 11 flaps survived and no vascular crisis occurred; 1 patient had a sinus at the edge of the flap, and the surgical area healed well after dressing change. All 11 patients were followed up 6-12 months, with an average of 9 months. The flap texture was good, the recipient site was in good shape, and there was no swelling; the foot contour was good, the shoes were comfortable to wear, and the movement was good. The incision at the donor site healed by first intention, leaving only linear and concealed scar, without obvious depression deformity, and the shoulder joint function was good. Conclusion On the premise of ensuring sufficient blood supply to the lower extremities and strengthening perioperative management, the microdissected thin TDAP to repair DFUs wounds can achieve better effectiveness and appearance; however, the prolonged operation time increases the probability of anesthesia and surgical risks in patients with DFUs.
Diabetic foot ulcer is the most serious complication of diabetes. In addition to diabetic peripheral neuropathy and lower extremity vascular disease, diabetic foot pressure abnormality is an independent risk factor for diabetic foot ulcers. This review summarizes the relationship between plantar pressure and diabetes, including the concept of the plantar pressure and its measurement methods, as well as the abnormal changes in the plantar pressure of diabetic patients. In addition, through the explanation of the mechanism of diabetic patients’ plantar pressure changes, the methods of releasing the abnormal plantar pressure are discussed, so as to prevent and treat the diabetic foot ulcers, and improve our understanding of it.
The paper introduces a training system for foot ulcer patients based on three axis accelerometer, which uses three axis accelerometer and Apple mobile phone platform to guide foot ulcer patients to carry out a variety of lower limb muscle tissues training. The acceleration values of three directions for the foot training is obtained by analog-to-digital conversion and transmitted to the Apple mobile phone via its Bluetooth low energy. The Apple mobile phone accomplishes acceleration data preprocessing, numerical filtering and adaptive dual-threshold processing by our developed application program, so as to achieve the purpose of foot gesture recognition. The experimental result shows that the design can effectively present the training situation and effect of patients, encourage patients to adhere to the training, and provide some reference data for doctors and patients.
Objective To systematically analyze the randomized controlled trials that compare tissue-engineered skin (TES) with conventional treatment for chronic diabetic foot ulcer (DFU) in terms of effectiveness and utilization.Methods We searched the electronic databases (PubMed, Embase, Cochrane Central Register of Controlled Trials, CBMWeb, CNKI, and VIP) in order to compare the efficiency and safety between TES and conventional treatment (CT) in the patients with DFU. In addition, we manually searched reference lists from original studies and review articles.Results Seven trials were included, which were all randomized controlled trials and had a duration of DFU over 6 weeks. There were 880 participants that met inclusion criteria in all studies, and all patients underwent pre-treatment procedures and were treated by TES (human skin equivalents, living skin equivalents or bioengineered skin, such as Graftskin, Dermagraft and Graftjacket) for 12 weeks. All trials had two groups: the treatment group and the control group, but the two trials divided the treatment groups into 3 different dosages and 2 different ulcer allocation subgroups, respectively. Meta-analysis results showed significant differences in the rate of complete wound closure (Plt;0.0001, 95%CI 0.08 to 0.20) and in the occurrence of complications and severe adverse events (P=0.008, 95%CI – 0.06 to – 0.01) between TES treated patients and conventionally treated patients. Conclusion The review shows TES improves completed closure of DFU compared with CT, and it is more effective in reducing side effects.
Objective To systematically review the efficacy of oxygen therapy for diabetic foot ulcers (DFUs). MethodsThe PubMed, Embase, Cochrane Library, CNKI, WanFang Data, and VIP databases were electronically searched to collect randomized controlled trials (RCT) on the efficacy of different oxygen therapies for DFUs from inception to April 1, 2024. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Statistical analysis was performed using R software, and GraphPad Prism was used for graphical representations. ResultsA total of 61 RCTs involving 4 306 DFUs cases were included in the analysis. The oxygen therapies examined primarily included hyperbaric oxygen, topical oxygen, and ozone therapy. The surface under the cumulative ranking curve (SUCRA) indicated that hyperbaric oxygen therapy ranked highest for healing rate, area reduction rate, and healing time (SUCRA values were 0.957, 0.868, and 0.869, respectively). However, hyperbaric oxygen therapy also ranked higher for amputation rate and adverse events (SUCRA values were 0.616 and 0.718, respectively). Further subgroup analysis revealed that hyperbaric oxygen therapy maintained the highest ranking in area reduction rate across subgroups defined by publication language and treatment duration. ConclusionHyperbaric oxygen therapy has advantages in terms of healing rate, area reduction rate, and healing time for DFUs, but it is also associated with higher amputation rates and adverse events. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To determine the effectiveness and safety of autologous platelet-rich gel in the management of diabetic foot ulcer. Methods We searched Cochrane Central Register of Controlled Trails (CENTRAL), MEDLINE or PubMed, EMbase, OVID Database, Chinese Biological Medicine Database (CBMDisc), CNKI, Chinese VIP Database and WANFANG Database. We also handsearched the bibliographies of retrieved articles and correlated proceedings. The systematic review was conducted using the method recommended by the Cochrane Collaboration. Results Four trials involving 216 patients were included. Meta-analyses showed (1) Diabetic foot ulcer healing rate: Autologous platelet-rich gel was superior to the standard care (Plt;0.000 01); (2) Diabetic foot ulcer reduction rate: Autologous platelet-rich gel was superior to the standard care (P=0.000 3); (3) Diabetic foot ulcer healing time: Autologous platelet-rich gel was superior to the standard care (Plt;0.000 01); (4) Complications: No patient in these trials had complications. Conclusions The limited current evidence shows that autologous platelet-rich gel is safe and effective in the short-term treatment for diabetic foot ulcer.
Diabetic foot ulcer is one of the severe chronic complications that lead to disability and death of diabetic patients. In order to solve this problem, adjuvant therapy studies of diabetic foot ulcers have increased in recent years. Extracorporeal shock wave therapy is a novel adjuvant therapy that has been approved by the US Food and Drug Administration for diabetic foot ulcers wounds. In this paper, the mechanisms of extracorporeal shock wave therapy for diabetic foot ulcers are described, including wound angiogenesis, wound tissue blood perfusion, nerve regeneration, granulation tissue proliferation, inflammatory response, anti-infection, migration and differentiation of mesenchymal stem cells and endothelial progenitor cells. This study aims to provide a theoretical basis for the clinical application of extracorporeal shock wave therapy in clinical treatment of diabetic foot ulcers.
ObjectiveTo explore the clinical efficacy of ultrasound debridement combined with autolytic debridement in the treatment of diabetic foot ulcers.MethodsA total of 60 diabetic foot ulcers patients who were diagnosed and treated in Jinshan Hospital of Fudan University from April 2019 to April 2020 were enrolled in the study and randomly divided into two groups, with 30 cases in each group. The trial group received autolytic cleansing combined with ultrasound debridement treatment, and the control group only received autolytic debridement treatment. The baseline conditions, wound treatment efficacy, number of dressing changes, length of hospital stay, treatment cost, wound healing time, wound shrinkage rate, and the time required for the wound to turn into 100% red granulation were compared between the two groups.ResultsThere was no statistically significant difference in gender, age, duration of diabetes or Wagner grade of diabetic foot between the two groups (P>0.05). The efficacy of wound healing in the trial group was better than that in the control group (Z=−2.146, P=0.032). The number of dressing changes [(11.76±2.23) vs. (17.34±4.43) times] and the length of stay [(18.03±3.73) vs. (25.43±4.43) d] in the trial group were lower than those in the control group, and the differences were statistically significant (P<0.05). The difference in treatment cost between the two groups was not statistically significant (P>0.05). The wound healing time of the trial group [(48.43±18.34) vs. (65.24±19.62) d], the wound shrinkage rate [(78.35±8.34)% vs. (56.53±6.54)%] and the time required for the wound to turn into 100% red granulation [(16.34±2.42) vs. (24.55±3.23) d] were better than those of the control group, and the differences were statistically significant (P<0.05). During the treatment process, no patient in the trial group had wound bleeding and had difficulty in stopping bleeding during ultrasonic debridement, and no patient had intolerable pain related to ultrasonic debridement. No patients in either group withdrew early.ConclusionsUltrasound debridement combined with autolytic debridement can effectively improve the curative effect of patients with diabetic foot ulcers and shorten the wound healing time. Therefore, it is worthy of promotion and application in the wound care of patients with diabetic foot ulcers.
ObjectiveTo systematically review the clinical efficacy and safety of hyperbaric oxygen therapy as adjunctive treatment for diabetic foot ulcers. MethodsSuch databases as The Cochrane Library (Issue 1, 2014), PubMed, EMbase, CBM, VIP, CNKI and WanFang Data were searched up to January 2014 for randomized controlled trials (RCTs) about hyperbaric oxygen therapy as adjunctive treatment for diabetic foot ulcers. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data, and assessed methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.2 software. ResultsFourteen RCTs involving 910 patients were included. The results of meta-analysis showed that, hyperbaric oxygen therapy combined with routine therapy was superior to routine therapy alone regarding ulcer healing rates (RR=2.16, 95%CI 1.43 to 3.26, P=0.000 3), incidence of major amputation (RR=0.20, 95%CI 0.10 to 0.38, P < 0.000 01), reduction of ulcer area (MD=1.73, 95%CI 1.34 to 2.11, P < 0.000 01), and improvement of transcutaneous oxygen tension (MD=14.75, 95%CI 2.01 to 27.48, P=0.02). However, no significant difference was found between the two group in minor amputation rates (RR=0.70, 95%CI 0.24 to 2.11, P=0.53). In addition, neither relevant serious adverse reaction nor complications were reported when using hyperbaric oxygen therapy as adjunctive treatment. ConclusionCurrent evidence shows that hyperbaric oxygen therapy as adjunctive treatment could improve ulcer healing and reduce incidence of major amputation.
