This study predicts the quality markers(Q-markers) for the cough-relieving and phlegm-expelling effects of Kening Granules based on pharmacodynamics, plasma drug chemistry, network pharmacology, and pharmacokinetics. Strong ammonia solution spray and phenol red secretion assays were employed to evaluate the cough-relieving and phlegm-expelling effects of Kening Granules. Twentysix absorbed prototype components of Kening Granules were identified by ultra high performance liquid chromatography coupled with QExactive Plus quadrupole/Orbitrap high resolution mass spectrometry(UHPLC-Q-Exactive Plus Orbitrap HRMS). Through network pharmacology, 11 potential active components were screened out for the cough-relieving and phlegm-expelling effects of Kening Granules. The 11 components acted on 40 common targets such as IL6, TLR4, and STAT3, which mainly participated in PI3K/Akt, HIF-1, and EGFR signaling pathways. Pharmacokinetic quantitative analysis was performed for 7 prototype components. Three compounds including azelaic acid, caffeic acid, and vanillin were identified as Q-markers for the cough-relieving and phlegm-expelling effects of Kening Granules based on their effectiveness, transmissibility, and measurability. The results of this study are of great significance for clarifying the pharmacological substance basis, optimizing the quality standards, and promoting the clinical application of Kening Granules.

Sophorae Flavescentis Radix is one of the commonly used traditional Chinese medicine in China, and a large amount of pharmaceutical residue generated during its processing and production is discarded as waste, which not only wastes resources but also pollutes the environment. Therefore, elucidating the chemical composition of the residue of Sophorae Flavescentis Radix and the differences between the residue and Sophorae Flavescentis Radix itself is of great significance for the comprehensive utilization of the residue. This study, based on ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) technology combined with multivariate statistical methods, provides a thorough characterization, identification, and differential analysis of the overall components of Sophorae Flavescentis Radix and its residue. Firstly, 61 compounds in Sophorae Flavescentis Radix were rapidly identified based on their precise molecular weight, fragment ions, and compound abundance, using a self-constructed compound database. Among them, 41 compounds were found in the residue, mainly alkaloids and flavonoids. Secondly, through principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA), 15 key compounds differentiating Sophorae Flavescentis Radix from its residue were identified. These included highly polar alkaloids, such as oxymatrine and oxysophocarpine, which showed significantly reduced content in the residue, and less polar flavonoids, such as kurarinone and kuraridin, which were more abundant in the residue. In summary, this paper clarifies the overall composition, structure, and content differences between Sophorae Flavescentis Radix and its residue, suggesting that the residue of Sophorae Flavescentis Radix can be used as a raw material for the extraction of its high-activity components, with promising potential for development and application in cosmetics and daily care. This research provides a scientific basis for the future comprehensive utilization of Sophorae Flavescentis Radix and its residue.

Aging is comprehensively influenced by multiple fac-tors such as internal genes,cellular metabolism,external envi-ronment,and lifestyle habits.Among them,epigenetic regula-tion plays a core role.Epigenetic modifications,including DNA methylation,histone modification,heterochromatin remodeling,and non-coding RNA regulation,act in concert with the three-di-mensional genome architecture to precisely regulate gene expres-sion.This review elaborates on the factors influencing epigenetic regulation,as well as the mechanisms of how epigenetics affects the occurrence of organismal aging and the corresponding inter-vention strategies,providing relevant insights for uncovering the mechanisms of aging and preventing/treating aging-related disea-ses.

Disorders of mitochondrial dynamics are closely re-lated to the development of neurodegenerative diseases(NDDs),which are characterized by the loss of neurons in brain and spinal cord cells.Diseases such as Alzheimer's disease,Parkinson's disease,Huntington's disease,and so on are in-volved in NDDs,which are often accompanied by disorders of mi-tochondrial dynamics during the development of these diseases.Recently,the researches on mitochondrial dynamics to study the pathogenesis of neurodegenerative diseases and related medica-tion innovation have garnered significant attention.This review focuses on the fundamental molecular processes of mitochondrial dynamics,such as mitochondrial transport,mitochondrial autoph-agy,and mitochondrial fission-fusion,and their molecular mecha-nisms in the pathogenesis of NDDs.It also outlines the recent research progress on Chinese materia medica and natural prod-ucts in ameliorating NDDs by modulating mitochondrial dynam-ics.The aim is to establish a foundation for researching innova-tive traditional Chinese medicine for NDDs-related diseases by focusing on mitochondrial dynamics.

Objective:To compare the differences in postoperative upper airway morphology and sleep apnea improvement between low temperature plasma ablation(LTPA)and traditional adenoidectomy(TAC)for severe adenoid hypertrophy in children.Methods:A total of 80 children with severe adenoid hypertrophy combined with obstructive sleep apnea-hypopnea syndrome(OSAHS)admitted to our hospital from January 2021 to January 2024 were randomly divided into two groups:LTPA group and TAC group,each with 40 cases.The study compared the upper airway morphological parameters(nasopharyngeal transverse diameter,sagittal diameter,nasopharyngeal airway volume,etc.),degree of OSAHS symptom improvement(apnea-hypopnea index,lowest blood oxygen saturation,etc.),intraoperative bleeding volume,surgical time,postoperative pain score,and incidence of postoperative complications in both groups before surgery,one week after surgery,one month after surgery,and three months after surgery.Results:The intraoperative blood loss in the LTPA group was significantly less than that in the TAC group,and the operation time was shorter(P＜0.05).Follow-up at 1 week,1 month,and 3 months postoperatively showed that both groups had significant improvements in upper airway morphology parameters compared to preoperative conditions.The increase in transverse diameter,sagittal diameter,and nasopharyngeal airway volume in the LTPA group was greater than in the TAC group(P＜0.05).Both groups also showed significant improvements in sleep-related breathing disorders,with a greater reduction in apnea-hypopnea index in the LTPA group compared to the TAC group(P＜0.05).Postoperative pain scores were lower in the LTPA group than in the TAC group(P＜0.05).The incidence of postoperative complications such as bleeding and nasopharyngeal stenosis was significantly lower in the LTPA group than in the TAC group(P＜0.05).Conclusions:Compared with traditional adenoid curettage,low temperature plasma ablation has the advantages of less surgical trauma,less intraoperative bleeding,less postoperative pain,better recovery of upper airway morphology and more significant improvement of sleep apnea in children with severe adenoid hypertrophy,and can be used as the preferred surgical mode for treating severe adenoid hypertrophy.
