Leonurus japonicas Houtt., a medicinal herb with a history dating back to the ancient classical text Shennong Bencao Jing—where it was noted for properties associated with "light body and long life"—has long been valued in traditional medicine under the names Chinese Motherwort or Siberian Motherwort. Renowned as the "sacred medicine of gynecology," it is recognized for effects including activating blood circulation, regulating menstruation, promoting diuresis, reducing swelling, and clearing heat and detoxifying, making it a common choice in clinical settings for treating various gynecological diseases. Within this herb, leonurine stands out as a key alkaloid, endowed with multiple biological activities such as anti-oxidation, anti-inflammation, and anti-apoptosis. Given that cardiovascular and central nervous system diseases pose significant "major health threats" to human life and health globally, and considering the side effects of many existing drugs, a comprehensive exploration of leonurine’s potential therapeutic role in these areas becomes highly relevant. This work focuses on reviewing the potential molecular therapeutic effects of leonurine on diseases affecting the cardiovascular and central nervous systems, emphasizes the latest findings in current research progress, and centers on its therapeutic impacts across different disease conditions. Currently, leonurine is in the clinical experiment stage, and the insights compiled aim to offer guidance for future studies into its molecular mechanisms and its broader clinical application.

A new study by researchers in China reveals that combining biochar, a charcoal-like soil enhancer, with a beneficial soil bacterium can help boost the growth and health of cut chrysanthemums, a commercially important flower troubled by soil disease from long-term monoculture. This simple, eco-friendly approach could hold promise for sustainable farming of many crops facing similar challenges.

In a visionary commentary that bridges the gap between theory and practice, leading environmental scientists from China are pioneering a new approach to assessing the health of aquatic ecosystems. Titled "Aquatic Ecosystem Health Assessment in China Based on Metacommunity Theory: From Theory to Practice," this insightful piece is co-authored by Prof. Xiaowei Jin from the China National Environmental Monitoring Centre and Prof. Fengchang Wu from the State Key Laboratory of Environmental Criteria and Risk Assessment, both based in Beijing, China. Their work offers a fresh perspective on how metacommunity theory can be applied to real-world environmental challenges.

This study presents a comprehensive exploration of fermented oats (FO) as a next-generation skincare ingredient with dual anti-inflammatory and skin barrier-restoring functions. By utilizing Saccharomyces cerevisiae fermentation, the authors successfully enhanced the bioactive composition of oats, significantly increasing β-glucan, proteins, flavonoids, amino acids, and their derivatives. These biochemical improvements translate into potent biological activity, positioning FO as a multifunctional soothing and repairing ingredient for sensitive and photodamaged skin. A major highlight of this research is its multi-model validation across cellular assays, zebrafish embryos, and 3D reconstructed skin. FO demonstrated a marked ability to modulate inflammatory pathways, including a 79.87% inhibition of TNF-α/TNFR1 binding, suppression of LPS-induced nitric oxide release, and reduction of neutrophil recruitment. These results collectively establish FO as a robust anti-inflammatory agent capable of suppressing both cytokine- and TRPV1-mediated inflammatory responses. Equally noteworthy is FO’s impact on skin barrier repair. In UVB-irradiated 3D skin models, FO significantly upregulated key structural proteins—including loricrin, filaggrin, transglutaminase 1, and caspase-14—which are essential for epidermal reinforcement, differentiation, and natural moisturizing factor formation. The ingredient also enhanced hydration by increasing both skin moisture content and AQP3 expression.

Overall, this study highlights fermented oats as an innovative, solvent-free, bioactivated skincare ingredient that simultaneously alleviates inflammation, repairs barrier damage, and improves hydration. Its strong mechanistic support and multi-level experimental confirmation underscore its potential as an effective soothing and repairing ingredient for sensitive skin formulations.
