Randomized Controlled Trial on the Efficacy and Safety of Xiang Lei Ointment in Diabetic-related Ulcer Management

Обзор

Diabetes is one of the major chronic diseases. Diabetic ulcers are important adverse outcomes of diabetes. Approximately 80% of lower - limb amputations are caused by diabetic foot ulcers, which are the main causes of disability and death among patients. Moreover, it places a huge burden on the medical insurance system. Currently, there are western medicine treatment guidelines for diabetic foot, yet the clinical efficacy is less than satisfactory. The amputation rate caused by diabetic foot ulcers continues to rise every year. There is an urgent clinical need for novel and effective intervention measures to address this disease. Macrophages are important cells involved in the inflammatory and proliferative phases of wounds, playing a crucial role in wound repair and reconstruction. Diabetes can cause wounds to remain in the pro - inflammatory stage continuously, leading to the aggregation of M1 macrophages and preventing their timely transformation into the pro - proliferative and repair stage. As a result, wounds exhibit persistent chronic inflammation and delayed tissue proliferation or remodeling. Xianglei Tangzu Ointment is a natural medicine approved for marketing by the National Medical Products Administration in November 2023. Its ingredients include Pogostemon cablin extract and asiaticoside. Research shows that the plant components in Xianglei Tangzu Ointment can promote the transformation of M1 macrophages into M2 macrophages, thereby reducing the inflammatory response and accelerating the proliferative repair of diabetic wounds. It has achieved certain curative effects in the clinical treatment of promoting wound healing. In order to use Xianglei Tangzu Ointment more precisely, accumulate clinical evidence - based medicine evidence, and explore the effectiveness and safety of Xianglei Tangzu Ointment in treating diabetic ulcers under the guidance of the chronic wound staging theory, clinical evidence - based medicine evidence needs to be obtained.
