Fresh-cut processing constitutes a pivotal technique in the origin processing of Chinese medicinal materials， with a long history documented in multiple materia medica. In recent years， it has garnered national policy support for its ability to prevent component loss and low processing efficiency associated with traditional drying-before-cutting methods. As of August 2025， 26 provinces and municipalities nationwide have cumulatively published 789 species for fresh-cut processing. Among these， 78 were included in the 2025 edition of the Pharmacopoeia of the People's Republic of China. However， the practice continues to face common challenges and difficulties， including ambiguous scientific understanding， fragmented standards， limited quality control approaches， and poor process stability. Based on this， this paper synthesises years of research findings to systematically elucidate the core mechanisms of fresh-cut processing. These encompass alterations to herbal tissue structure during cutting， post-processing changes in constituents， and physiological-biochemical processes such as plant stress responses and shifts in endogenous enzyme activity. It also summarises influencing factors， including inherent herbal properties， cutting timing and methods， and environmental conditions like temperature， humidity， and microbial presence. Based on this overview of fresh-cutting mechanisms， subsequent research should advance in four directions：Clarifying the scientific principles of fresh-cutting， overcoming technical bottlenecks， upgrading intelligent equipment， and establishing quality standards and evaluation systems. This study provides a theoretical foundation and scientific basis for future research on fresh-cutting in traditional Chinese medicine（TCM）， promoting its deeper practical application within the industry and contributing to the high-quality development of TCM industry and the modernization of TCM.

Chronic heart failure （CHF） is an end-stage cardiac syndrome driven by multiple factors. Its pathological process involves interactions of multiple pathways such as energy metabolism dysfunction， neuroendocrine dysregulation， and myocardial fibrosis. Although current clinical medicine can alleviate symptoms through single-target approaches， significant limitations in reversing cardiac remodeling and disease progression remain. Puerarin， a major bioactive isoflavone constituent derived from Pueraria lobata， exhibits multidimensional pharmacological effects， such as vasodilatory effects， regulation of neuroendocrine balance， enhancement of metabolic homeostasis， and suppression of myocardial apoptosis. This review systematically integrated puerarin's multi-target regulatory network， elucidating its mechanisms such as improving energy metabolism by AMP-activated protein kinase/mechanistic target of rapamycin （AMPK/mTOR） pathway， inhibiting fibrosis mediated by transforming growth factor-β （TGF-β）/Smad signals， and attenuating oxidative-inflammatory cascades by regulating nuclear factor erythroid 2 （E₂）-related factor 2/nuclear transcription factor-κB（Nrf2/NF-κB） axis. Clinical research data was used to validate its efficacy in improving the left ventricular ejection function and reducing the therapeutic potential of cardiovascular events' risks. The study proposed that puerarin's "systemic regulation" characteristic breaks through the limitations of traditional single-target drugs and prospected its clinical translation pathway based on metabolomics and nano-delivery technology， offering an integrative perspective from molecular mechanisms to precise therapy for the research on modernization of traditional Chinese medicine.

Objective To explore the effects of tripterygium glycosides(TGs)on adipocyte differentiation,inflam-mation,and fibrosis of orbital fibroblasts(OFs)in thyroid associated ophthalmopathy(TAO).Methods OFs isolated from 12 TAO patients were cultured and identified.CCK-8 experiment was used to detect the effect of different concentra-tions of TGs(0,12.5,25.0,50.0,100.0 mg·L-1)on the activity of OFs.Then,adipocyte differentiation phenotypes of OFs were induced and divided into a control group,an adipocyte differentiation group(DM),and TG groups(12.5,25.0,and 50.0 mg·L-1 TGs).Inflammation phenotypes of OFs were induced and divided into a control group,an IL-1 β group,and TG groups(12.5,25.0,and 50.0 mg·L-1 TGs).Fibrosis phenotypes of OFs were induced and divided into a control group,a TGF-βi group,and TG groups(12.5,25.0,and 50.0 mg·L-1 TGs).Oil red O staining was used to detect the formation of lipid droplets in OFs of adipocyte differentiation phenotype.ELISA was used to measure IL-6 and TNF-α levels in OFs of inflammation phenotype and HA levels in OFs of fibrosis phenotype.Transwell experiment was used to detect the cell migration rate of OFs of fibrosis phenotype.Real time quantitative polymerase chain reaction(RT-qPCR)and Western blot were used to detect the expression levels of PPAR-γ,c/EBP-α,FABP-4,perilipin-1,and adiponectin mRNAs and pro-teins in OFs of adipocyte differentiation phenotype,the expression levels of IL-6,TNF-α,COX-2,MCP-1 and ICAM-1 mR-NAs and proteins in OFs of inflammation phenotype,and the expression levels of Vimentin,Fibronectin,COL1A1,COL1A2 and ACTA2 mRNAs and proteins in OFs of fibrosis phenotype.Results The cells were identified as OFs.12.5,25.0,and 50.0 mg·L-1 of TGs had no significant effect on OF activity and these three concentrations were used in the subsequent ex-periment.In OFs of adipocyte differentiation phenotype,the number of orange red lipid droplets greatly decreased after TG treatment.The expression levels of PPAR-γ,c/EBP-α,FABP-4,perilipin-1,and adiponectin mRNAs and proteins in cells of TG groups were significantly lower than those of the DM group(all P＜0.05).In OFs of inflammation phenotype,IL-6 and TNF-α levels in supernatant and cells of TG groups were significantly decreased,compared with those of the IL-1βgroup(all P＜0.05).The expression levels of COX-2,MCP-1,and ICAM-1 mRNAs and proteins in cells of TG groups were significantly lower than those of the IL-1 β group(all P＜0.05).In OFs of fibrosis phenotype,the cell migration rates,HA levels in cell culture supernatant,and the expression levels of Vimentin,Fibronectin,COL1A1,COL1A2,and ACTA2 mR-NAs and proteins in cells of TG groups were significant lower than those of the TGF-β1 group(all P＜0.05).Conclusion TGs can inhibit the adipocyte differentiation,IL-1 β-induced inflammatory responses and TGF-β1-induced fibrosis of TAO-OFs.

Periodontitis constitutes the primary cause of tooth loss among adults in China. The disease is characterized by the high morbidity, which significantly impairs both oral and systemic health. As the key insights of initial periodontal therapy, subgingival scaling and root planing (SRP) have been considered as simple, effective, and cost-efficient treatment approaches for managing periodontal inflammation. Substantial published evidences indicated that the majority of patients diagnosed with periodontitis could achieve lifelong retention of their natural teeth through standardized initial periodontal therapy, rigorous plaque control, and long-term supportive periodontal treatment. However, the proficiency in periodontal diagnosis and treatment among general dental practitioners in China is heterogeneous, with a notable scarcity of periodontists and a suboptimal level of SRP standardization. Drawing upon over four decades of clinical expertise from Peking University School and Hospital of Stomatology as well as comprehensive literature reviews, this paper meticulously outlines the standardized procedures for SRP, aiming at guiding clinicians to perform standardized SRP step by step, and thereby enhancing clinical efficacy of periodontal treatment, promoting periodontal health, and ultimately improving patients′ quality of life.
