Effect of Yinqi Ointment on Wound Morphology and Growth Factor in Treating Diabetic Foot Ulcer

Objective: To investigate the effect of Yinqi ointment on wound morphology and growth factor in treating diabetic foot ulcer(DFU).Methods: From December 2016 to December 2017, 92 cases of DFU with deficiency of both Qi and Yin syndrome were randomly divided into treatment group and control group(44 cases in each group). The treatment group was treated with Yinqi ointment, while the control group was treated with mupirocin ointment. After 4 weeks of treatment, the ulcer healing effect, ulcer area, granulation tissue, epithelial tissue coverage,pain score, and dynamic analysis of vascular endothelial growth factor(VEGF), epidermis growth factor(EGF), and basic fibroblast growth factor(bFGF) in local granulation tissue were statistically analyzed before and after treatment in both groups. Results: The total effective rate was 88.37% in the treatment group and 74.42% in the control group. The wound reduction rate, epithelial tissue coverage rate, granulation tissue growth rate, and local pain relief rate in the treatment group were significantly superior to those in the control group(P 0.05). Through the local granulation detection, the treatment group and the control group have increased VEGF, EGF, and bFGF, but the treatment group increased the role of growth factor than the control group. Conclusion: Yinqi ointment can promote the healing of DFU, and its mechanism may be related to the increase of the content of growth factor in granulation tissue.

Investigating the effects of walnut ointment on non-healing burn wounds

Effective treatments for non-healing burn wounds are an unmet need for 95% of burn sufferers. Approaches currently available to treat non-healing burn wounds are not satisfactory due to undesirable side-effects or expense. The anti-oxidation and antibacterial activities of walnuts are recommended for treating chronic diseases. Walnut ointment has been developed and successfully applied to treat non-healing burn wounds in our hospital for decades. We report herein a detailed retrospective case review examining patients’ response to the walnut ointment. The walnut ointment has shortened healing time of non-healing burn wounds and improved clinical outcomes. In order to investigate the mechanism of action, walnut ointment has been applied on wounds of porcine full-thickness burn wound models. Histological and immunohistochemical analysis indicated our walnut ointment supports wound healing through promoting keratinocyte proliferation and differentiation. Taken together, we recommend the walnut ointment offers an effective and economical treatment for patients presenting with non-healing burn wounds.

黑布药膏的化学成分表征研究

黑布药膏系常用的院内制剂,由五倍子、蜈蚣等制成,临床疗效确切,但其药效物质基础尚未全面阐明。本研究采用超高效液相色谱-高分辨飞行时间质谱联用技术（UPLC-Q-TOF-MS/MS）对黑布药膏及其生药混合物的化学成分进行定性分析,并探讨了制剂前后成分的差异。在电喷雾（ESI）正、负离子模式下,根据精确相对分子质量、特征碎片离子、色谱保留时间等初步鉴定出73个化合物,其中生药混合物、黑布药膏分别鉴定了57、65个化合物,包括鞣质类、酚酸类、核苷类、氨基酸类等,在制备过程中,化学结构发生变化的成分主要集中在鞣质类。结果表明,UPLC-Q-TOF-MS/MS技术可以灵敏、高效地表征黑布药膏制剂中所含的化学成分及其在制剂过程中的结构变化,为充分阐明黑布药膏药效物质基础和制剂工艺的合理性及后续制剂质量标准提升研究提供重要依据。
