Osteoarthritis (OA) is the most common chronic degenerative joint disease, characterized by cartilage damage, synovial inflammation, subchondral bone sclerosis, marginal bone loss, and osteophyte development. Clinical manifestations include inflammatory joint pain, swelling, osteophytes, and limitation of motion. The pathogenesis of osteoarthritis has not yet been fully uncovered. ⋯ Therefore, gut flora imbalance as a pathogenic factor in OA has become a hotspot topic of research, with potential therapeutic connotations. In this paper, we review the role of the gut microbiota in the pathogenesis of OA, describe its relationship with common OA risk factors, and address candidate gut microbiota markers for OA diagnosis. In addition, with focus on OA therapies, we discuss the effects of direct and indirect interventions targeting the gut microbiota, as well as the impact of gut bacteria on the efficacy of OA drugs.

With the continuous advancements in modern medicine, significant progress has been made in the treatment of lung cancer. Current standard treatments, such as surgery, chemotherapy, radiotherapy, targeted therapy, and immunotherapy, have notably improved patient survival. However, the adverse effects associated with these therapies limit their use and impact the overall treatment process. ⋯ These include inhibiting lung cancer cell growth and proliferation, inhibiting cancer cell invasion and metastasis, suppressing angiogenesis and epithelial-mesenchymal transition (EMT), and modulating antitumor inflammatory responses and immune evasion. This paper aims to summarize recent advancements in the application of TCM for lung cancer, emphasizing its unique advantages and distinctive features. In promoting the benefits of TCM, we seek to provide valuable insights for the integrated treatment of lung cancer.

Panax notoginseng (PN) root is a renowned nutritional supplement, health food additive, and traditional medicine that maintains homeostasis within the human microcirculatory system. Notoginsenoside R1 (NG-R1), an active compound derived from PN root, has been reported to possess various pharmacological activities, including anti-inflammatory, antioxidant, anticancer, antimicrobial, and angiogenic effects. However, NG-R1's pharmacokinetic properties and pharmacological activities have not been systematically elucidated. ⋯ NG-R1 offers potentially protective effects against numerous diseases, including cardiovascular, neurological, renal, pulmonary, bone, and diabetes-related conditions. Although the pharmacological activities and diverse effects of NG-R1 have been demonstrated in various diseases, its clinical applications are limited by poor bioavailability. Several strategies have been explored to improve the pharmacokinetic profile of NG-R1, making it a promising candidate for drug development.

Oxidative stress represents a pivotal mechanism in the pathogenesis of numerous chronic diseases. The Kelch-like ECH-associated protein 1-transcription factor NF-E2 p45-related factor 2 (KEAP1-NRF2) pathway plays a crucial role in maintaining redox homeostasis and regulating a multitude of biological processes such as inflammation, protein homeostasis, and metabolic homeostasis. ⋯ This paper highlights an overview of current strategies to modulate KEAP1-NRF2, as well as recent advances in the use of natural compounds and traditional Chinese medicine, with a view to providing meaningful guidelines for drug discovery and development targeting KEAP1-NRF2. Additionally, it discusses the challenges associated with harnessing NRF2 as a therapeutic target.

Palmatine (PAL) and berberine are both classified as protoberberine alkaloids, derived from several traditional Chinese herbs such as Coptis chinensis Franch. and Phellodendron chinense Schneid. These compounds are extensively used in treating dysentery and colitis. PAL is one of the crucial quality markers for these plants in the Chinese Pharmacopoeia. ⋯ Its role in fostering M2 polarization and modulating the inflammatory cytokine profile was further confirmed in vitro. Importantly, the anti-inflammatory effects were primarily linked to AMP-activated protein kinase activation, which subsequently inhibited the nuclear factor-kappa B pathway. These findings highlight OPAL as a crucial active metabolite responsible for the therapeutic effects of PAL against UC, emphasizing its potential as a novel treatment for this condition.
