Abstract: Currently, nutraceuticals and functional food/cosmeceutical sectors are seeking natural molecules to develop various types of phytopharmaceutical products. Flavonoids have been reported in antioxidant and many medical/pharmacological activities. Monochoria angustifolia or Siam violet pearl medicinal plant is the newest species of the genus Monochoria C. Presl, which have long been consumed as food and herbal medicines. Though previous work showed that apigenin-7-O-glucoside is the most abundant antioxidant phytochemical found in this medicinal plant, the report on anti-aging activity is still lacking and needs to be filled in. The objective of this work is to explore anti-aging capacities of the most abundant antioxidant phytochemical reported in this plant using both in silico and in vitro assessments. In addition, pharmacokinetic properties were predicted. Interestingly, the results from both in silico and in vitro analysis showed a similar trend that apigenin-7- O-glucoside is a potential anti-aging agent against three enzymes. The pharmacokinetic properties, such as adsorption, distribution, metabolism, excretion and toxicity (ADMET), of this compound are also provided in this work. The current study is also the first report on anti-aging properties of this Thai medicinal plant. However, the safety and efficacy of future developed products from this compound and clinical study should be determined in the future.

Abstract

Skin aging has been associated with the onset of various skin issues, and recent studies have identified an increase in Cdc42 activity in naturally aging mice. While previous literature has suggested that CASIN, a specific inhibitor of Cdc42 activity, may possess anti-aging properties, its specific effects on the epidermis and dermis, as well as the underlying mechanisms in naturally aging mice, remain unclear. Our study revealed that CASIN demonstrated the ability to increase epidermal and dermal thickness, enhance dermal-epidermal junction, and stimulate collagen and elastic fiber synthesis in 9-, 15-, and 24-month-old C57BL/6 mice in vivo. Moreover, CASIN was found to enhance the proliferation, differentiation, and colony formation and restore the cytoskeletal morphology of primary keratinocytes in naturally aging skin in vitro. Furthermore, the anti-aging properties of CASIN on primary fibroblasts in aging mice were mediated by the ribosomal protein RPL4 using proteomic sequencing, influencing collagen synthesis and cytoskeletal morphology both in vitro and in vivo. Meanwhile, both subcutaneous injection and topical application exhibited anti-aging effects for a duration of 21 days. Additionally, CASIN exhibited anti-inflammatory properties, while reduced expression of RPL4 was associated with increased inflammation in the skin of naturally aging mice. Taken together, our results unveil a novel function of RPL4 in skin aging, providing a foundational basis for future investigations into ribosomal proteins. And CASIN shows promise as a potential anti-aging agent for naturally aging mouse skin, suggesting potential applications in the field.

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。
