Abstract: Grape (Vitis vinifera L.) stems, a by-product of winemaking, possess significant potential value due to their rich polyphenolic composition, which allows their exploitation for cosmetic and pharmaceutical applications. This presents a promising opportunity for valorisation aimed at developing innovative products with potential health-promoting effects. In this study, the polyphenolic profile of extracts from grape stems of seven white grape varieties was determined using spectrophotometric and chromatographic methods, specifically high-performance liquid chromatography coupled with a photodiode array detector and electrospray ionization multi-stage mass spectrometry (HPLCPDA-ESI-MSn), as well as on their ferric-reducing antioxidant power (FRAP) and radical scavenging capacity, using 2,2-diphenyl-1-picrylhydrazyl (DPPH• ) and 2,2′ -azino-bis(3-ethylbenzothiazoline-6- sulfonic acid (ABTS•+ ) radicals. This study also evaluated the anti-aging activity and skin depigmenting activity of these extracts. These findings revealed a diverse polyphenolic profile, encompassing proanthocyanidins and catechin derivatives (PCDs), phenolic acids, and flavonols. Among the varieties studied, ‘Códega do Larinho’ exhibited the highest concentrations of six distinct polyphenols and the highest total phenolic content. It also demonstrated the highest results for antioxidant capacity and elastase and tyrosinase inhibition. Pearson’s correlation analysis showed a significant positive correlation between certain PCDs with both FRAP and DPPH assays, as well as between the identified flavonols and anti-elastase activity. These results underscore the potential health benefits of grape stem extracts and emphasize the importance of their polyphenolic composition in enhancing antioxidant and anti-aging properties, thus supporting their application in different industries.

Abstract: This study was conducted to investigate the differences in chemical composition between red (RGBs) and yellow ginseng berries (YGBs) and their whitening and anti-aging skincare effects. The differences in the chemical composition between RGB and YGB were analyzed by ultrahigh-performance liquid chromatography tandem quadrupole electrostatic field orbit trap mass spectrometry (UHPLC-Q-Exactive-MS/MS) combined with multivariate statistics. An aging model was established using UVB radiation induction, and the whitening and anti-aging effects of the two ginseng berries were verified in vitro and in vivo using cell biology (HaCaT and B16-F10 cells) and zebrafish model organisms. A total of 31 differential compounds, including saponins, flavonoids, phenolic acids, and other chemical constituents, were identified between the two groups. Superoxide dismutase (SOD) activity was more significantly increased (p < 0.05) and malondialdehyde (MDA) content was more significantly decreased (p < 0.01) in RGB more than YGB induced by UVB ultraviolet radiation. In terms of whitening effects, YGB was more effective in inhibiting the melanin content of B16-F10 cells (p < 0.01). The results of zebrafish experiments were consistent with those of in vitro experiments and cell biology experiments. The DCFH fluorescence staining results revealed that both ginseng berries were able to significantly reduce the level of reactive oxygen species (ROS) in zebrafish (p < 0.01). Comparison of chemical composition and skin care activities based on RGB and YGB can provide a theoretical basis for the deep development and utilization of ginseng berry resources.

慢性伤口治疗中普遍存在的问题？

原创：卢魁

慢性伤口治疗中普遍是什么问题困扰着患者呢？

问题一：悲观思想，认为患了不治之症
事实上，精神压力和疾病之间，存在着一条明显的纽带。对疾病切勿忧虑恐惧，悲观失望，郁郁寡欢，闷闷不乐，要学会自我克制、自我调节，要心胸宽广，豁达大度，树立战胜疾病的信念，要有毅力和勇气。
问题二:
轻信广告和传言，相信“神药”
慢性伤口是一种长期慢性疾病，其中很多疾病都是没有办法完全根治的，因此必须要有长期和疾病做斗争的思想认识。切勿相信广告所说的秘方、神药，以免上当受骗，耽误病情。
问题三：
为什么症状控制后仍需要长期观察预防复发？
到目前为止，慢性伤口大部分尚不能根治，需要长期治疗让伤口愈合。症状减轻仅意味着病情得到控制，并未完全治愈。体内的病变可能并没有真正停止，停药后或受到外界刺激仍会复发。只有改变生活习惯、合理功能锻炼、合理使用控制病情的药物(慢作用药物)，才能减缓或阻止上述过程的进展。
