摘要：目的:本研究将从环鸟苷酸腺苷酸合成酶-干扰素基因刺激因子(Cyclic guanine nucleotide adenine nucleotide synthetase-Stimulator of interferon genes,cGAS-STING)通路入手,明确湿润暴露疗法/湿润烧伤膏(Moist exposed burn therapy/Moist exposed burn ointment,MEBT/MEBO)能否通过调控cGAS-STING信号通路减轻创面组织炎症反应状态,从而加快糖尿病创面修复的进程,为之后的临床治疗和科学研究提供可靠的参考数据。方法:1.通过网络药理学数据库筛选出MEBT/MEBO治疗糖尿病创面的活性成分和关键靶点,并对其进行京都基因和基因组百科全书(Kyoto Encyclopedia of Genes and Genomes,KEGG)和基因本体(Gene Ontology,GO)富集分析和蛋白质相互作用网络(Protein-protein interaction,PPI)分析,对活性成分和关键靶点进行分子对接验证其结合能力。2.动物实验验证:(1)选取48只Wistar雄性大鼠随机分为4组:空白组、MEBO组、贝复新组、对照组,其中空白组构建正常大鼠急性创面模型,MEBO组、贝复新组和对照组构建糖尿病大鼠创面模型。(2)通过HE染色观察各组大鼠造模后第3、7、14天创面愈合情况、组织形态学变化。(3)采用Western Blot、Real-time qPCR检测cGAS-STING通路相关蛋白表达变化差异及mRNA转录水平差异。结果:(1)通过网络药理学方法筛选出77个湿润烧伤膏和糖尿病创面的交集靶点,显示刺槐素、汉黄芩素、槲皮素、吴茱萸次碱等为湿润烧伤膏核心活性成分,对交集靶点进行PPI网络分析筛选出TP53、TNF、HSP90AA1等关键靶点,KEGG富集分析结果显示TNF、PI3K-Akt、AGE-RAGE信号通路在湿润烧伤膏对糖尿病创面的治疗中起到重要作用,GO富集分析结果显示这些交集靶点的生物过程主要涉及炎症反应调节和血管新生过程。我们进一步对核心活性成分和关键靶点进行分子对接,结果显示均具有较强结合活性。(2)创面愈合情况:造模后第3天,各组之间的创面愈合率无明显差异(P>0.05);造模后第7、14天,与对照组相比,空白组、MEBO组和贝复新组的创面愈合...

摘要：Objective: Many topicals claim an efficacious role in skin scar management with limited evidence. Our aim is to present a clear format for functional testing of a skin scarring ointment, using noninvasive and invasive measurements, categorizing findings under the physiological, structural, and mechanical parameters of a scar., Approach: A double-blinded, randomized volunteer research study of 45 subjects receiving an ointment composing of natural ingredients against a widely used antiscarring topical used as a positive control with temporal sequential punch biopsies (up to 16 weeks) was evaluated using noninvasive quantitative devices and validated by gene and protein studies., Results: Outcome measures included physiological, mechanical, and structural features of scars. Significant non-invasive findings included an increase in skin hydration (p?<?0.05) at week (W) 4, 8, and 12, and elasticity (W16; p?=?0.009). These findings were validated by immunohistochemistry (IHC) and quantitative real-time PCR (qRT-PCR). Hyaluronic acid IHC (W4 p?=?0.014, W12 p?=?0.034, and W16 p?=?0.042), qRT-PCR (W16 p?=?0.049); Collagen I (W16 p?=?0.034, and 0.049) IHC and qRT-PCR, respectively. Collagen III qRT-PCR (W12 p?=?0.035, and W16 p?=?0.32); elastin IHC (W12 p?=?0.044); and fibronectin IHC (W4 p?=?0.009, W12 p?=?0.038, and W16 p = 0.026)., Innovation: Utilizing this model allows for quantitative, objective evaluation of any topical, where previously there has been a paucity of relevant methods to evaluate their effect., Conclusions: The positive effect of a topical formulation with an unknown mechanism of action on early cutaneous scar maturation over progressive sequential time points is now evidenced using noninvasive and invasive techniques with the findings categorized on the basis of scarring parameters.

摘要：Aim. This study aimed to compare the effect of MEBO versus 0.2% hyaluronic acid gel (Gengigel?) applied to the palatal donor site on postoperative pain reduction and wound healing after free gingival graft harvesting. Methodology. Thirty-nine patients with different mucogingival defects were included in this study for harvesting a free gingival graft (FGG) for soft tissue augmentation. Patients were randomly assigned into three equal groups: group I (MEBO), group II (0.2% HA Gengigel?), and group III (control). Postoperative pain was recorded by using the Visual Analogue Scale (VAS). Analgesic consumption was recorded for 7 days postoperatively. Wound size was measured at baseline and on days 3, 7, 14, and 21. Postoperative healing of the palatal wound was assessed by the VAS score for color match on days 3, 7, 14, 21, and 42. Results. Results of this study showed significant postoperative pain reduction for the three groups; MEBO showed statistically significant less VAS score compared to the other two groups, while HA showed statistically significant less VAS score compared to the control group. Both MEBO and HA showed statistically significant less total analgesic consumption. No statistically significant difference was observed between groups for wound size. MEBO showed statistically significant higher VAS for color match. Conclusions. Both treatment modalities could reduce postoperative pain following harvesting of FGG and improve the palatal wound healing. However, MEBO showed better outcomes in terms of postoperative pain and color match.
