Objective To review and evaluate the clinical application of autologous plateletrich gel (APG) in refractory chronic diabetic cutaneous ulcers. Methods The latest literature was extensively reviewed, and the potential mechanism of APG for healing diabetic cutaneous ulcers was discussed. Results APG accelerated the ulcer healing, especially in healing the refractory diabetic cutaneous ulcers, and the high-level growth factors from the platelet releasate were thought to be the major potential mechanism of the APG action. Conclusion APG can promote the healing of refractory chronic diabetic cutaneous ulcers. Topical haemotherapy withAPG may be considered an adjuvant treatment of a multidisciplinary process and may be useful to the effective therapy of cutaneous ulcers.
Collagenase can promote wound healing, and its effect depends on the degradation of necrotic tissue and the collagen degradation products produced by collagenase. The possible mechanisms include accelerating re-epithelialization, promoting the formation of granulation tissue and blood vessels, and regulating inflammatory response. At present, clinical studies have shown that collagenase combined with sharp debridement or negative pressure wound therapy can significantly promote the healing of diabetic foot ulcers, and its efficacy is similar to that of hydrocolloid occlusive dressing and silver-containing wound dressings. Collagenase can promote the repair of diabetic foot ulcers, but its effect is affected by many factors, and large-sample, good design, high quality and multi-center randomized controlled trials are still needed to explore its efficacy and appropriate use conditions. This paper expounds that collagenase is one of the options in the treatment of diabetic foot ulcers from mechanism and clinical effect.
The annual incidence of diabetic foot ulcers in China is as high as 8.1%, which ranks first among the causes of chronic wounds in China. Although through the efforts of several generations of podiatrists and the building of multidisciplinary collaboration team, the major amputation rate in patients with diabetic foot ulcers in China has been decreased significantly, it is still far higher than the level of developed countries in Europe and the United States. Therefore, in order to cope with the increasing occurrence and recurrence of refractory diabetic foot ulcers, in addition to further optimizing the construction of multidisciplinary collaboration team, it is an urgent topic for us to explore the construction of a multidisciplinary integrated team to seamlessly connect the diagnosis and treatment of different aspects of foot disease. This article describes the importance and necessity of building a wound repair center with Chinese characteristics, which is a model of multidisciplinary integrated team, aiming at provide a theoretical basis for establishing a multidisciplinary integrated management model and realizing seamless connection between diagnosis and treatment, so as to further improve the cure rate of diabetic foot ulcers.
The Diabetic Foot and Peripheral Vascular Disease Study Group, Chinese Diabetes Society, released an expert advice Recommendations of Chinese Experts on the Standardized Diagnosis and Treatment of Diabetic Foot During Coronavirus Disease (COVID-19) Pandemic, and the International Diabetic Foot Care Group and D-Foot International released a document Fast-track Pathway for Diabetic Foot Ulceration During COVID-19 Crisis: A Document from International Diabetic Foot Care Group and D-Foot International during the 2020 outbreak, respectively. Both have the same goals, but the implementation focuses are different. The aim of this article is to give an interpretation of both expert advices in terms of the general principles, the epidemic prevention and control, the family, community and hospitalization management model of diabetic foot, the holistic principle of diabetic foot standardized management, and the telemedicine application in the late epidemic period.
目的：对糖尿病足溃疡中面积和体积计算的方法学的临床应用进行评价。方法：广泛查阅文献,并结合我们的实际，对计算糖尿病足溃疡中面积和体积的各种方法效果进行综合分析。结果：目前常用于计算糖尿病足溃疡面积的方法有公式法、数码照像计算法、无菌薄膜勾边法等，但以数码照像计算法更准确，更易被患者接受；目前常用于计算糖尿病足溃疡体积的方法有公式法、媒介填充法、CT足部扫描法等，但以媒介填充法更经济易行。结论：数码照像计算法是目前较好的用于测量糖尿病足溃疡面积的方法，而媒介填充法是较简便易行的测量糖尿病足溃疡体积的方法。
ObjectiveTo review the research progress of adrenergic β-antagonists on wounds and diabetic chronic cutaneous ulcers healing in recent years, and to investigate its application prospect in diabetic foot ulcer (DFU).MethodsThe latest literature about the role of adrenergic β-antagonists in wounds and diabetic chronic cutaneous ulcers healing was extensively reviewed, and the mechanisms of adrenergic β-antagonists for wounds and its potential benefit for DFU were analyzed thoroughly.ResultsThe adrenergic β-antagonists can accelerate the wound healing. The possible mechanisms include accelerating re-epithelialization, promoting angiogenesis, improving neuropathy, and regulating inflammation and growth factors, etc. At present clinical research data showed that the adrenergic β-antagonists may be an adjuvant treatment for diabetic chronic cutaneous ulcers.ConclusionAdrenergic β-antagonists maybe promote the healing of wounds and diabetic chronic cutaneous ulcers. However, more long-term follow-up and high-quality randomized control studies are needed to further verify their efficacy and safety for DFU.
Objective To evaluate the effectiveness and safety of sarpogrelate hydrochloride for patients with peripheral arterial disease (PAD). Methods The randomized controlled trials (RCTs) on PAD treated by sarpogrelate hydrochloride were identified from CBM (1978 to September 2011), CNKI (1979 to May 2011), PubMed (1950 to May 2011), EMbase (1970 to May 2011) and The Cochrane Library (Issue 3, 2011). According to the criteria of the Cochrane Handbook, two reviewers independently screened the studies, extracted and cross-checked the data, and assessed the methodological quality. Then meta-analysis was conducted by using RevMan 5.0 software. Results Nine RCTs involving 522 patients and 532 limbs were included, with low methodological quality in most trials. The results of meta-analyses indicated that compared with the conventional treatment, sarpogrelate hydrochloride could reduce the area of ulcers (MD= –3.22, 95%CI –3.99 to –2.45), and it could increase the ankle-brachial index (SMD=0.49, 95%CI 0.07 to 0.91), blood flow of dorsalis pedis artery (MD=0.16, 95%CI 0.09 to 0.23) and pain-free walking distance (MD=200.87, 95%CI 3.39 to 398.36). Five trials reported the adverse effects of sarpogrelate hydrochloride, most of which were mild gastrointestinal symptoms. Conclusion Based on the review, sarpogrelate hydrochloride may have positive effect on patients with PAD. However, the evidence is not b enough due to the general low methodological quality, so the reliable conclusion has to be drawn with more high quality studies in future.
