Intrinsic and extrinsic factors, including lifestyle and sun exposure, can contribute to cell senescence, which impairs skin homeostasis, that may in turn lead to skin aging. Senescent cells have a specific secretome, called the senescence-associated secretory phenotype (SASP) that includes MMPs, CXCLs and S100A8/9. Reducing the SASP with senotherapeutics is a promising strategy to reduce skin aging. Here we evaluated the effect of a formula containing niacinamide and hyaluronic acid, which are known to limit senescence and skin aging. We conducted three different studies. (1) Ex vivo explants treated with the formula had more collagen and glycosaminoglycan. (2) In a clinical trial with forty-four women, two months of treatment improved fne lines, wrinkles, luminosity, smoothness, homogeneity, and plumpness. (3) In a third study on thirty women, we treated one arm for two months and took skin biopsies to study gene expression. 101 mRNAs and 13 miRNAs were differentially expressed. We observed a likely senomorphic efect, as there was a decrease in many SASP genes including MMP12 and CXCL9 and a significant downregulation of autocrine signaling genes: S100A8 and S100A9. These pharmaco-clinical results are the first to demonstrate the senomorphic properties of an effective anti-aging formula in skin.

Abstract
Phytochemicals help mitigate skin aging by scavenging free radicals, modulating key enzymatic pathways, and promoting the skin’s structural integrity. Carotenoids, vitamins, essential fatty acids, and phenolic compounds work by acting as antioxidants, inhibiting enzymes like hyaluronidase, collagenase, and elastase, which degrade skin structure, and reducing levels of inflammatory markers (IL-6, IL-8, etc.) and matrix metalloproteinases (MMP-1, MMP- 2) linked to aging. Recent research highlights that plant-based phytochemicals can improve skin elasticity, reduce hyperpigmentation, prevent the breakdown of important skin proteins, and support wound healing, making them valuable components for skin care and treatments. This review explores the multifaceted roles of phytochemicals in maintaining and improving skin health, highlighting their mechanisms of action and potential in skin anti-aging

随着现在人们生活水平的逐渐提高,有一种“富贵病”在生活中逐渐出现,渐渐地已经成为生活中的常见病,它就是我们常说的糖尿病。而今天小编不给大家讲糖尿病的相关知识,而是讲一种因糖尿病而引起的一种并发症,它的名字叫糖尿病足!
下肢静脉溃疡
下肢静脉性溃疡,俗称“老烂腿”,是下肢静脉疾病的常见临床表现。下肢静脉性溃疡常常反复发作,溃疡久治不愈,严重影响患者的正常生活,因此一旦出现下肢静脉性溃疡的现象,患者应该及时到正规医院的血管外科就医,以查清病因,对症下药。
糖尿病足骨髓炎(Diabetic foot osteomyelitis,DFO)与更高的踝上截肢率相关。尽管DFO有着很高的发生率和糟糕的预后,然而针对其治疗却缺乏高质量的证据。由于缺乏基于证据的指南,导致其治疗方法多种多样。作者咨询了14个外科专家,采用Delphi方法获得了关于DFO诊断、治疗和管理的专家共识。同时作者希望有更多有力的研究和更清晰的指南,以便能改善外科治疗的结果。
