Abstract: This comprehensive review explores the pivotal roles of glycation and oxidative stress in the aging process of the skin, their targeted therapeutic applications in aesthetic and regenerative medicine, as well as anti-aging interventions. Glycation, a biochemical process involving the non-enzymatic attachment of sugars to proteins, lipids, or nucleic acids, culminates in the formation of Advanced Glycation End products (AGEs). These AGEs are significant contributors to aging and various chronic ailments, triggering oxidative stress and inflammatory pathways, thereby manifesting as wrinkles, diminished skin elasticity, and other age-related dermal alterations. A central focus of this review is the synergistic interplay between Hyaluronic Acid (HA) and Trehalose in combating these aging mechanisms. HA, renowned for its anti-inflammatory and antioxidative properties, assumes a pivotal role in modulating Reactive Oxygen Species (ROS) levels and safeguarding against oxidative damage. Concurrently, trehalose targetsglycation and oxidative stress, exhibiting promising outcomes in augmenting skin health, providing Ultraviolet B (UVB) photoprotection, and manifesting notable anti-photoaging effects. The combined administration of HA and trehalose not only addresses existing skin damage but also confers preventive and reparative benefits, particularly in stabilizing HA and mitigating glycation-induced stress. Their synergistic action significantly enhances skin quality and mitigates inflammation. The implications of these findings are profound for the future of anti-aging therapeutics in aesthetic medicine, suggesting that the integration of HA and trehalose holds promise for revolutionary advancements in preserving skin vitality and health. Moreover this paper underscores the imperative for continued research into the combined efficacy of these compounds, advocating for innovative therapeutic modalities in aesthetic medicine and enhanced strategies for combating aging, glycation, and oxidative stress.

Abstract
Longevity genes and senescence-related signaling proteins are crucial targets in aging research, which aims to enhance the healthy period and quality of life. Identifying these target proteins remains challenging because of the need for precise categorization and validation methods. Our multifaceted approach combined bioinformatics with transcriptomic data to identify collagen as a key element associated with the lifespan of the model organism, Caenorhabditis elegans. By analyzing transcriptomic data from long-lived mutants that involved mechanisms such as antioxidation, dietary restriction, and genetic background, we identified collagen as a common longevity-associated gene. We validated these findings by confirming that collagen peptides positively affect lifespan, thereby strengthening the validity of the target. Further verification through healthspan factors in C. elegans and functional assays in skin fibroblasts provided additional evidence of the role of collagen in organismal aging. Specifically, our study revealed that collagen type VII is a significant target protein for mitigating age-related decline. By validating these findings across different aging models and cell-based studies, we present compelling evidence for the anti-aging effects of collagen type VII, highlighting its potential as a target for promoting healthy aging. This study proposes that collagen not only serves as an indicative marker of organismal longevity across various senescence-related signaling pathways, but also offers a mechanistic understanding of skin degeneration. Consequently, collagen is an effective target for interventions aimed at mitigating skin aging. This study underscores the potential of collagen type VII (bonding collagen T7) as a therapeutic target for enhancing skin health and overall longevity.

糖尿病足的切口设计是糖尿病足局部脓肿及窦道治疗的第一步,也是最关键的一步之一,由于糖尿病足脓肿和窦道的多样性,以及糖尿病足病人全身情况的不一致,因此,要找到糖尿病足切口的设计规律比较困难,我们根据大量的临床实践,制定了以下的一些原则。
在上节中提到局部鉴别皮肤组织的“死活”是一个难题,有读者问有关在创面表面用“亚甲基蓝”染料染色来鉴别的问题,这种方法是一种比较古老的方法,对于相对较干净的伤口的效果比较好,对于严重感染的伤口容易出现误报,而且为了最大程度的保护足的结构和功能,一般采取蚕食性的方法进行清创,用这些染料染色后,反而有时候会干扰对肉芽组织生长的判断,容易造成清创过多的情况,因此,目前应用较少(也比较难得到有证书能够在临床应用的这种染料)。
针对“杨氏扩散”的特殊性、沿着窦道扩散的缺点及足部手术的原则,我们设计了一种沿着窦道行纵向切开的“刘氏切法”(图1),特点是:(1)沿着窦道做平行于足纵轴切开;(2)一般在窦道开口及窦道末端切开;(3)切口长度3-4CM;(4)足弓部足底边缘部的切口非常关键。
足底溃疡是糖尿病足治疗的难点。尤其是足跟。从理论上讲,足底的组织结构较足背要致密很多,其具有很强的对于损伤的防护及对于细菌感染的抵抗能力,即使在糖尿病状态下,也有一定的防御能力。
伤口世界平台生态圈,以“关爱人间所有伤口患者”为愿景,连接、整合和拓展线上和线下的管理慢性伤口的资源,倡导远程、就近和居家管理慢性伤口,解决伤口专家的碎片化时间的价值创造、诊疗经验的裂变复制、和患者的就近、居家和低成本管理慢性伤口的问题。
