Evidence-based recommendations for the treatment of recurrent aphthous stomatitis: insights from an umbrella review

Review

作者: AlShehri, Bayan K. ; Alhomood, Khalid S. ; Abuhasna, Waad R. ; Al-Shamiri, Hashem M. ; Al-Maweri, Sadeq Ali ; Al-Aizari, Nader A. ; Alzahrani, Saeed R.

OBJECTIVE:

To compare the effectiveness and safety of pharmacological, physical, and complementary interventions for recurrent aphthous stomatitis (RAS) across clinically relevant outcomes.

METHODS:

This umbrella review was conducted according to PRISMA and Cochrane guidance and registered in PROSPERO (CRD42024594292). PubMed, Scopus, and the Cochrane Library were searched through August 2025. Eligible studies were systematic reviews, meta-analyses, or network meta-analyses evaluating treatments for RAS. Methodological quality was assessed using AMSTAR 2, and overlap of primary studies was quantified using the corrected covered area.

RESULTS:

A total of 41 reviews were included. Topical corticosteroids and low-level laser therapy consistently reduced pain and shortened healing time, although evidence for recurrence prevention was limited. Hyaluronic acid and herbal agents demonstrated favorable short-term efficacy with good safety profiles. Systemic agents such as colchicine and thalidomide showed benefit in severe or refractory RAS, but were constrained by the adverse effects and low-certainty evidence.

CONCLUSION:

Evidence supports topical corticosteroids, hyaluronic acid, and laser therapy for short-term symptom control in RAS, while systemic agents should be reserved for selected refractory cases.

Intra-articular injection of high versus low molecular weight hyaluronic acid in adhesive capsulitis; randomized trial

Article

作者: Mohebbi, Rezvaneh ; Mir, Mahshad ; Mohammadnezhad, Ghader ; Raeissadat, Seyed Ahmad ; Parhizgar, Alireza ; Esmaily, Hadi

BACKGROUND:

Adhesive capsulitis (AC) is a chronic inflammatory condition with limited range of motion (ROM) in the glenohumeral joint. The main goals in managing AC are pain reduction and returning joint function. Intra-articular hyaluronic acid (HA) has been considered a safe modality in AC. This study compared the effectiveness of intra-articular injection of low molecular weight (LMW) with high molecular weight (HMW) HA in patients with AC.

METHODS:

Fifty-six patients with AC were randomized in this triple-blinded clinical trial. All underwent standard physical therapy. The outcomes were visual analog scale (VAS), Oxford shoulder score (OSS), active ROM, and patient satisfaction at 4, 12, and 24 weeks.

RESULTS:

No significant differences were detected in between-group variables at baseline. Both groups showed marked improvement in VAS, OSS, and ROM over time. At four weeks LMW-HA group had lower pain (P = 0.049). Conversely, the trend of VAS at 12-week and 24-week endpoints favors HMW-HA (Baseline to endpoint: -5.48 ± 1.68 and -3.91 ± 1.31 reduction in VAS as the primary outcome, P < 0.001). Satisfaction had significantly improved in both groups.

CONCLUSION:

HMW-HA was associated with greater pain reduction and functional improvement compared with LMW-HA.

TRIAL REGISTRATION:

The trial protocol was registered at the Iranian Registry of Clinical Trials (IRCT), a WHO Primary Register setup (registration No: IRCT20170608034390N4; First registration date: 01/01/2020).

Midface volumization and skin quality enhancement with a hyaluronic acid–polynucleotide hybrid filler: a 24-week prospective open-label study

Article

作者: Park, Kui Young ; Youn, Choon Shik ; Lee, So Young

BACKGROUND:

Facial aging is characterized by midface volume loss from structural and dermal atrophy.

OBJECTIVES:

To evaluate the efficacy and safety of a hyaluronic acid-polynucleotide (HA-PN) hybrid filler for temporary restoration of anteromedial cheek volume.

METHODS:

In this single-center, open-label trial, 15 adults with moderate-to-severe anteromedial cheek volume loss (Mid-Face Volume Deficit Scale [MFVDS] score ≥ 3) received up to 1 mL HA-PN hybrid filler per side. Evaluations at baseline and weeks 4, 12, and 24 comprised blinded photographic MFVDS rating (primary endpoint: ≥1-grade improvement at week 4), GAIS (Global Aesthetic Improvement Scale) score, participant satisfaction, transepidermal water loss, skin hydration, elasticity, and adverse events.

RESULTS:

All participants completed the study without serious adverse events. MFVDS scores improved significantly at week 4 and remained improved through weeks 12 and 24. GAIS and satisfaction scores paralleled these gains. Transepidermal water loss decreased and hydration increased over time, and Cutometer parameters (R2 R5 R7) showed progressive improvements in elasticity, indicating enhanced skin quality along with midface volumization.

CONCLUSIONS:

The HA-PN hybrid filler demonstrated improvements in midface volume restoration with concurrent improvements in skin barrier function, hydration, and elasticity, and was well tolerated over 24 weeks within the constraints of the study design.

【临床抗衰修复专题】皮肤抗衰在医学美容中的最新应用进展（2025年）——浙江大学医学院附属第一医院

皮肤衰老主要表现为干燥粗糙、无光泽、脂褐质及老年斑增多、皱纹、松弛及下垂等，不仅影响皮肤美观，还严重损害其健康。本文系统综述了当前皮肤抗衰治疗的方法和最新研究进展，涵盖了生物活性因子、声光电技术、外源性侵入性治疗，以及外泌体技术、微生物组研究，旨在为抗衰老提供更安全、个性化的治疗选择，并推动皮肤抗衰老治疗的进一步发展和创新。随着社会的进步和人们生活水平的提高，对维持年轻和健康外观的需求不断上升。皮肤作为人体最大的器官，其老化过程不仅受内在老化因素的影响，还与环境因素、生活方式等多种外在因素紧密相关。皮肤抗衰老医学是医学美容领域中的一个重要分支，始终致力于探索和开发有效的治疗手段，以延缓皮肤老化、提升皮肤质量、恢复皮肤的年轻状态。近年来，得益于生物技术、材料科学、表观遗传学和人工智能等多学科的交叉融合，皮肤抗衰老医学的研究取得了显著的进展，特别是在生物活性因子、外泌体技术、微生物组研究和数字化技术应用等领域展现出巨大的潜力和广阔的应用前景。本文综述了面部年轻化治疗的最新研究进展，旨在推动皮肤抗衰老治疗的进一步发展和创新。一、面部年轻化治疗方法 1.1 生物活性因子：生物活性因子主要包括抗氧化剂、生长因子、生物活性肽及激素。抗氧化剂如辅酶Q10、维生素E、C及茶多酚等，能有效清除自由基，抑制氧化应激反应。纳米颗粒技术的应用显著提高了辅酶Q10的生物利用度，而茶多酚则通过抗氧化和抗炎双重机制发挥抗衰老作用。近年来，酶促抗氧化剂（如超氧化物歧化酶）和合成抗氧化剂（如EUK134）在改善肤色不均和光老化防护方面效果显著。生长因子通过促进细胞增殖与分化来改善皮肤老化症状，联合微针技术更可显著增强皮肤活力。生物活性肽稳定性和皮肤渗透性优异，研究证明，其口服可减缓皮肤胶原降解，改善皮肤水合作用，增加弹性并减少皱纹形成。皮肤衰老受内分泌系统影响，多种激素变化会引发皮肤功能和结构改变。雌激素可促进皮肤修复，褪黑素及其代谢产物能有效修复紫外线诱导的DNA损伤。研究发现，甲状旁腺激素调节钙磷代谢对皮肤细胞功能和屏障形成至关重要，可能影响皮肤衰老，但尚无直接证据。此外，甲状腺激素及肾上腺分泌的多种激素对维持皮肤屏障功能具有重要影响。 1.2 外源性治疗技术：激光、射频和聚焦超声等非侵入性能量源设备，通过热刺激效应促进真皮层胶原蛋白新生，改善皮肤松弛和皱纹等老化症状。研究表明，联合应用双极射频与透明质酸（Hyaluronic Acid，HA）中胚层疗法可产生协同效应，提升皮肤质量。侵入性技术如手术切除多余皮肤、SMAS筋膜层提升术及脂肪填充等技术通过直接干预面部组织结构，有效改善面部松弛和体积缺失等衰老特征。透明质酸不仅能够填充皱纹、改善面部轮廓、维持皮肤水合作用与弹性，联合富血小板血浆更可显著增强其作用。针对其长期支撑效果欠佳的局限性，研究者开发了透明质酸水凝胶和硅酸锂钙生物陶瓷微球等材料，能够促进血管生成相关因子及胶原蛋白相关基因的表达。胶原蛋白具有机械强度优异、可生物降解且能诱导内源性胶原蛋白生成等优势，临床研究表明，注射后可显著减少光老化性皱纹。此外，聚己内酯、羟基磷灰石钙、聚二氧环己酮和聚L-乳酸等半永久性真皮填充剂通过持续刺激成纤维细胞增殖，增加胶原蛋白密度，可提供更持久的美学效果。这些材料的创新应用推动了面部年轻化治疗的精准化和长效化发展。肉毒杆菌毒素通过抑制肌肉收缩来减少动态皱纹，其疗效已得到广泛验证。最新研究表明，肉毒毒素微滴注射技术可有效改善面部细纹，提升中下面部轮廓，为颈部年轻化和下颌骨边缘重塑提供了微创治疗方案。这一技术不仅拓展了肉毒毒素的适应证范围，也为面部美容治疗策略的多元化发展提供了新的思路。二、面部年轻化研究趋势

外泌体：干细胞及其外泌体，通过恢复细胞功能、促进胶原蛋白合成、降低基质金属蛋白酶表达及调节细胞信号传导途径，实现皮肤的抗衰。相比干细胞治疗，外泌体作为无细胞治疗手段，致瘤性和免疫原性风险低，且有潜力作为药物或基因递送载体。多种干细胞源性外泌体可恢复成纤维细胞功能，促进Ⅰ型胶原蛋白表达，逆转皮肤衰老进程。外泌体中的微小RNA(microRNA，miRNA)和蛋白质发挥关键作用，如骨髓间充质干细胞源性外泌体中的miR-29b-3p能减轻紫外线诱导的皮肤成纤维细胞光老化，过表达miR-1246的外泌体可激活自噬改善UVB诱导的光老化。此外，人体皮肤成纤维细胞、人脐静脉内皮细胞等其他细胞外泌体，以及牛奶、植物来源等天然外泌体，均能保护皮肤免受紫外线诱导的光老化，改善皮肤衰老状态。外泌体在面部年轻化领域备受关注，但具体作用靶点和机制仍需深入研究。大规模制备外泌体，由于细胞培养过程中细胞来源和培养条件的差异、纯化过程的低效性以及分离提纯方法的复杂性，导致外泌体的纯度和质量不稳定。此外，缺乏统一的鉴定、定量和表征标准，以及生产过程中的交叉污染等问题也会影响外泌体质量的一致性，使得外泌体的应用受限。 2.2 生物治疗：微生物群在皮肤衰老过程中起到关键作用。年轻皮肤中，丰富的痤疮丙酸杆菌等有益菌，可维持皮肤健康。随着皮肤衰老，其微环境改变引发微生物群落结构失衡、多样性降低，致使有害菌数量相对增加，进而造成皮肤屏障功能受损、水分保持能力下降。同时，菌群失衡引发的炎症反应及氧化应激水平升高，进一步加速皮肤细胞衰老和损伤。多项研究证实了微生物群落结构变化与皮肤衰老存在紧密联系。Jugé R及Dréno B等发现衰老皮肤微生物多样性下降，致病菌相对丰度增加，这种变化与皮肤生理特征改变相关。益生菌、益生元、后生元等微生物相关物质对皮肤衰老具有一定益处。Lee DE等发现口服植物乳杆菌HY7714可改善皮肤皱纹等。Zhang L等发现，口服或局部使用低聚木糖八周，可改善肠道和皮肤微生物群，从而延缓皮肤衰老。含有EPI-7发酵滤液的测试产品能显著改善皮肤屏障功能、弹性和真皮密度。另有研究指出，YM-4培养滤液能上调细胞增殖相关基因的表达，促进透明质酸合成和屏障功能改善，展现出抗衰老特性。皮肤微生物群与衰老相关疾病如皮肤癌、银屑病等也存在关联，菌群失衡可能加剧皮肤炎症反应和免疫紊乱。目前关于微生物群对皮肤衰老影响的研究已取得一定进展，但仍需深入探讨以更好地理解其机制，并开发基于微生物群的皮肤抗衰老策略。 2.3 表观遗传学：表观遗传学研究基因活性、表达变化引发的遗传变异，主要涵盖DNA甲基化、组蛋白修饰及非编码RNA的改变。其变化受生活方式、压力、饮食、环境影响，个体间存在差异且具有可逆性。DNA甲基化是关键表观遗传修饰，在人类健康与疾病中意义重大。如二氢杨梅素可抑制原代人角质细胞的DNA甲基化，降低表观遗传年龄。饥饿能通过修饰神经元组蛋白延缓果蝇衰老。miRNA作为预测皮肤年龄的表观遗传分子钟，在皮肤老化中作用关键。已有研究表明，促进miR-146a表达，可维护皮肤细胞健康。皮肤作为人体中最大的器官，有八大功能，即屏障功能、吸收功能、感觉功能、再生功能、体温调节、排泄功能、调节功能、代谢功能和免疫功能。皮肤衰老是生理性、不可避免的，其表现形式多种多样，包括真皮层厚度降低、皮肤弹力下降，皮肤松弛、皱纹、色泽暗沉、角化过度、基因修复缺陷、免疫缺陷及易受感染等。随着人民生活水平的不断提高，人们对于抗衰老的需求也越发强烈，因此探究皮肤衰老的分子机制及如何延缓皮肤衰老成为目前的研究热点之一。三、皮肤衰老的主要原因皮肤衰老是整体性的，过程极其复杂，其原因众多，与年龄、性别、种族及遗传等有关，并受到社会条件、生活环境、职业、季节等因素的影响，主要可以分为内源性和外源性两大类因素等。 1.1 内源性衰老：内源性衰老即自然衰老，其主要机制为氧化应激、DNA损伤、表观基因组、线粒体损伤、端粒缩短、免疫衰退和神经内分泌原因等。 1.2 外源性衰老：外源性衰老主要是由各类辐射、病原菌和病毒、异物、风吹日晒、臭氧等天然有害气体、大气污染及吸烟等引起的衰老，其中日光中紫外线辐射是最主要因素，导致了光老化。长波紫外线和中波紫外线会对皮肤造成辐射，促进自由基的产生，如产生活性氧（Reactive oxygen species, ROS）导致细胞微环境变化，造成DNA、蛋白质和脂质等损伤［3-4］。与自然衰老相比，光老化引起的皮肤衰老更为严重。光老化比自然衰老产生的皱纹粗且深，另外衰老速度更快，而且长期的日光照射还可能会诱发皮肤癌等更严重的皮肤问题。四、皮肤衰老的微环境机制随着研究的不断深入，人们发现微环境的变化也可以导致皮肤衰老的发生，具体机制包括：氧化应激、基因调控、线粒体损伤、端粒缩短、免疫衰退和神经内分泌损伤等。 2.1 氧化应激：在正常情况下，机体代谢会产生ROS，与机体的正常生理过程密切相关，体内ROS的动态平衡需要抗氧化防御系统维持。伴随着年龄的增长，人体抗氧化的能力也逐渐衰退，主要是抗氧化酶的活性降低，这会导致ROS发生清除障碍，在微环境中积聚。当机体无法修复ROS引起的细胞损伤，细胞状态将会改变甚至丧失分化状态，继而细胞破裂、凋亡，最终皮肤衰老［6］。ROS大量积聚对皮肤衰老造成的影响主要表现在以下几个方面［7］。 2.1.1 对核酸的损伤：①ROS能够从戊糖部分夺取氢，造成碱基缺失甚至DNA主链断裂，导致基因突变；②ROS与双链DNA中的碱基发生加成反应，生成异常光化产物，进而引起碱基破坏，导致突变；③ROS使核酸发生交联，阻碍DNA复制。如果机体的修复能力不能完全修复这些损伤，那么DNA这些损伤将传至子代细胞，使得子代细胞发生细胞功能异常或者增殖，进而导致皮肤衰老甚至皮肤癌。 2.1.2 对蛋白质的损伤：ROS能够与氨基酸发生反应，改变其结构和空间构象，引起肽链断裂、聚合与交联，进而皮肤中胶原蛋白（Collagen protein）、弹性蛋白（Elastin）和表皮生长因子受体蛋白（Epidermal growth factor receptor，EGFR）等发生改变，影响蛋白质的功能和微环境代谢，影响信号传导及酶的活性，使皮肤变薄、长皱纹，弹性变差，细胞生长减缓，最终引起皮肤衰老。 2.1.3 对糖的损伤：ROS可攻击皮肤中的透明质酸分子和蛋白聚糖等糖链，经氧化脱氢使糖链断裂，解聚为糖醛类产物，影响细胞正常功能，同时也会导致细胞屏障破坏，与细胞内核酸、蛋白质等发生交联变性。 2.1.4 对脂质的损伤：ROS能够与生物膜上的不饱和脂肪酸发生反应，导致膜通透性的改变，造成对膜固有结构的破坏，使得原有的膜流动性丧失；另外，膜中镶嵌的蛋白质分子和多糖可因移位或氧化而导致失活，进而影响膜信息传递、物质运输等功能。ROS也可引起细胞内微环境的改变，形成丙二醛（Malondialdehyde，MDA），MDA是一种强交联剂，容易与蛋白质或核酸发生交联，形成溶酶体难以清除的荧光性物质脂褐素（Lipofuscin，LPF），它可沉积于皮肤的结缔组织，当达到一定数量时即可形成肉眼可见的老年斑。 2.2 基因调控：基因和遗传是造成皮肤衰老的关键原因之一，基因所引起的自然老化是难以避免和逆转的。研究资料表明，皮肤衰老与基因组、表观遗传等异常密切相关。 DNA甲基化和组蛋白修饰等途径通过对p16、p53、p63等多种衰老相关基因的调控，进而在表观遗传学机制层面控制衰老进程，表观遗传途径的异常会影响基因组的稳定性，进而导致皮肤衰老［8］。DNA甲基化即DNA甲基转移酶催化S腺苷甲硫氨酸的甲基转移到DNA分子中胞嘧啶环的第5位碳原子上，形成5-甲基胞嘧啶(5-mC)，它与衰老、肿瘤、多种遗传病和自身免疫性疾病的发生密切相关，是生物的表观遗传时钟，与衰老强烈相关。细胞衰老的同时，DNA甲基化也发生多样性改变，整体上基因组甲基化水平下降，Heyn H等进行全基因组甲基化测序（Whole genome bisulfite sequencing，WGBS）使用亚硫酸氢盐处理基因，证明年龄增加的过程中全基因组呈现低甲基化。也伴随着某些特殊基因的高甲基化，编码雌激素受体的DNA就在衰老过程中发生高甲基化。组蛋白多个位点上发生多种类型的修饰，能招募不同的效应蛋白，修饰水平呈现不同的变化趋势，衰老基因正常的表达调控遭到破坏，染色质结构状态也受到影响。如H3K9me3是一种常见的抑制性组蛋白修饰，主要与异染色质的形成有关。异染色质是缺乏转录活动，具有固缩特性的染色体。在线虫、果蝇和人类的衰老过程中H3K9me3修饰水平变化各不相同，且都有发现异染色质结构丢失的现象。 2.3 线粒体损伤：线粒体代谢反应为机体提供能量，但同时也产生了大量ROS，过量的ROS就会导致线粒体DNA（mtDNA）的氧化损伤，如8-羟基脱氧鸟苷（8-hydroxy-2 deoxyguanosine，8-OHDG）的产生就会导致mtDNA突变。mtDNA损伤时，可造成编码呼吸链的蛋白质合成障碍，从而导致呼吸链的完整性遭到破坏，引起细胞供能不足，最终发生衰老。与衰老相关的线粒体突变有大片mtDNA缺失、点突变、碱基插入、替代环或D环（D-loop）区小的串联重复和DNA重排。另外，ROS对线粒体膜的损伤和线粒体钙稳态的破坏也会导致衰老［16］。 2.4 端粒缩短：端粒缩短是发现最早最具特征性的导致细胞衰老的机制之一［17］。端粒衰老假说认为细胞发生分裂的次数是由遗传基因通过端粒程序决定的。随着细胞发生分裂，端粒也逐渐缩短，其缩短至一定程度时，程序则发出停止分裂信号，细胞开始启动细胞衰老程序［18］。 2.5 免疫衰退：皮肤中的免疫细胞减少，免疫组织衰退老化、功能紊乱，如线粒体异常、自噬／吞噬功能缺陷、内质网应激、泛素／蛋白酶系统缺陷、DNA损伤反应的激活、T细胞老化等都会影响免疫细胞的功能，皮肤抵御外界损伤的能力下降，易发生皮肤感染，最终导致皮肤衰老［19-20］。 2.6 神经及内分泌损伤：皮肤的神经源性因子，如P物质（Substance-p，SP）和钙基因相关肽（Calcitonin gene-related peptide，CGRP）等与光老化密切相关，参与皮肤光老化的发生过程；促肾上腺皮质素释放素（Corticotropin-releasing hormone，CRH）则参与过量的氧化应激反应，与皮肤的炎症反应与衰老密切相关［21-22］。体内内分泌环境的变化也会导致皮肤内源性衰老，尤其雌激素的影响最为显著，女性卵巢分泌雌激素的能力降低时，会加速皮肤衰老的进程。研究表明，双侧卵巢均切除妇女较双侧卵巢保留妇女的皮肤弹性、湿度和保湿性明显降低，皮肤皱纹增多，皮肤衰老更显著［23］。五、应对皮肤衰老的对策随着对衰老机制的探索，已经从整体水平、器官水平迈向细胞水平和分子水平，针对微环境层面的抗衰策略也越来越受到关注。 3.1 抗氧化：人体中一系列的内源性抗氧化剂可以消耗过量的ROS，从而避免自由基的损害［24］。如谷胱甘肽（Glutathione，r-glutamyl cysteingl+glycine，GSH）中含有谷氨酸、胱氨酸以及甘氨酸，有抗氧化作用，可以减少皮肤中的自由基，阻止黑色素的生成，缓解炎症，维持线粒体的功能，促进新陈代谢，达到祛斑祛皱和延缓衰老的目的。含硒的辅酶Q10（Coenzyme Q10，CoQ10）又称泛醌（Ubiquinone，UQ）可以中和自由基，阻止污染物以及其他毒素损害皮肤，其中还含有有助于激活皮肤细胞，消除自由基的维生素A、C、E，对保护皮肤组织和修复至关重要，可以抵抗光老化对皮肤的影响。另外，尿酸（Uric acid）也具有抗氧化功效。天然的外源性抗氧化剂也可以抵消或减轻部分自由基损伤，在对抗皮肤衰老上也有一定的作用，如巴西莓、阿拉伊浆果、β胡萝卜素，白藜芦醇等。某些生物制剂、天然中草药制剂、化学合成和半合成制剂也可通过抗氧化达到抗衰效果［25］。抗氧化手段可针对多个机制对抗皮肤衰老，已成为抗皮肤衰老的重要方法，尤其在抗初老和抗衰化妆品中的应用极为广泛。 3.2 活性DNA导入衰老细胞及DNA修复：通过生物技术，为衰老细胞导入活性DNA，弥补衰老细胞的基因缺陷，通过修补基因物质，为老化的细胞注入新的活力，或是用反义RNA封闭特定的抑制DNA合成的基因，使DNA恢复原有代谢活力，是延缓皮肤衰老研究的新方向。此外，DNA修复作用也在一些中草药中被发现，如枸杞、人参、马齿苋、三七、生姜、刺五加、五味子、山茱萸等。 3.3 衰老细胞导入活性端粒酶或提高端粒酶活性：衰老细胞导入活性端粒酶或提高端粒酶活性，延长端粒长度，可以有效对抗端粒衰老。但端粒酶在多种癌细胞中都有大量表达，与癌细胞的无限增殖密切相关，于生物体的改造仍有很多风险及不确定因素。此外，端粒酶技术仅仅从单个细胞的角度延缓衰老，属于基因抗衰成分，而整个生物体的新陈代谢是一套统一而复杂的系统，目前研究的核心是延缓整个机体的衰老。某些中药，如锁阳、黄精、五味子、马齿苋等具有上调端粒的长度和活性的作用［26］。 3.4 其他对策 3.4.1 针对免疫衰退：向衰老机体中注射胸腺激素或健康机体来源的免疫细胞可以在一定程度上预防免疫衰退和延缓衰退速度。此外，能够多向调节免疫功能的中草药也有许多，如刺五加、冬虫夏草、灵芝、三七、人参、黄芪、马齿苋、沙棘等［27］。 3.4.2 激活内分泌系统的多项功能或补充多种激素：人参、红景天、玉竹、蒺藜、生地、百合、枸杞子、蒲公英、甘草等具有改善神经内分泌的作用，能够激活肾上腺皮质的功能，使垂体-肾上腺皮质轴兴奋，改善垂体-性腺轴的功能［28］。补充激素，如褪黑素（Melatonin，MT）能够刺激表皮细胞生长，促进成纤维细胞生成胶原蛋白和透明质酸，延缓皮肤衰老。 3.4.3 针对光老化的对策：近年来，多项研究已广泛证实紫外线易引起皮肤的光老化，虽然光老化对皮肤的损伤最为严重，但采取防晒措施，防止皮肤遭受紫外线的过度辐射，就可以控制皮肤光老化的速度或减轻光老化对皮肤的损伤。防晒是防止紫外线损伤的首要措施，其中防晒剂是关键物质，分为物理、化学和天然防晒剂三种，物理和化学防晒共同作用的效果最佳。临床上还发现一些具有吸收紫外线功能的天然动植物，如仙人球、芦荟、海藻、黄芪、甲壳素、沙棘、银杏等。另外，还可以使用抗氧化剂、维A酸或医美手术等多种手段来对抗光老化［29-30］。 3.4.4 干细胞相关的皮肤抗衰老：目前，用于抗衰老研究的干细胞主要有间充质干细胞（Mesenchymal stem cells，MSCs）、诱导性多能干细胞（Induced Pluripotent stem cell，iPSC）以及其他一些新型干细胞等，其中应用较多的是MSCs，MSCs通过旁分泌方式释放可溶性细胞因子，发挥再生、抗炎、促血管生成、抗凋亡、抗氧化应激等作用，MSCs衍生的分泌产物，如外泌体和凋亡小体也在延缓皮肤衰老方面有极大的研究价值［31-32］。六、小结随着社会发展及老龄化社会的到来，国内外关于衰老及抗衰老的研究逐渐增多。皮肤衰老作为人体普遍衰老的直接体现，研究皮肤衰老的机制和探索抗衰老对策对于探究衰老的本质有重要意义。皮肤衰老是多重因素共同作用的复杂过程。衰老皮肤的结构及皮肤细胞与其胞外微环境都会随之发生变化，在这一过程中，衰老细胞积聚并诱导皮肤或其他组织细胞的衰老和相关功能障碍。目前，人们对皮肤衰老微环境的研究仍存在许多未知领域。现代抗衰老对策的研究，要针对多种机制和因素采取全面的针对性对策，不能用某个单一的理论来回答所有衰老问题，其中皮肤干细胞疗法在抗衰老研究中具有极大的应用前景。
