Background: The global rise in visual impairment, driven by population aging, the increasing prevalence of lifestyle-related chronic diseases, and environmental factors, has made it a critical public health concern, highlighting the urgent need for effective preventive strategies and eye health maintenance. Cuscutae Semen (CS), a traditional Chinese herbal medicine long regarded for its vision-enhancing properties, has been widely used to support ocular health. However, its underlying molecular mechanisms and bioactive constituents remain poorly understood, limiting its modernization and broader clinical application. Objective: This study aims to investigate the restorative effects of CS on visual impairment, elucidate its underlying mechanisms, and identify potential active components. Methods: A zebrafish model of visual impairment was established using mepanipyrim to simulate retinal structural damage and visual dysfunction. The therapeutic effects of CS were systematically evaluated through behavioral analyses and histomorphological observations. To elucidate the underlying mechanisms, an integrated approach was employed, combining transcriptome sequencing (RNA-seq), reverse transcription quantitative polymerase chain reaction validation, and immunofluorescence staining to identify critical genes and pathways involved. Furthermore, macroporous resin column chromatography was employed for the fractionation and screening of potential active components. Results: CS treatment significantly alleviated mepanipyrim-induced ocular abnormalities in zebrafish, restoring approximately 82% of the observed morphological defects. Behavioral assessments revealed that CS-treated zebrafish exhibited markedly increased swimming speed and distance, indicating enhanced visual light sensitivity. Histopathological analysis demonstrated that CS effectively repaired the structure of retinal cell layers. RNA-seq revealed that CS broadly reversed mepanipyrim-induced gene expression disturbances, suggesting a restorative effect on transcriptomic homeostasis. Gene Ontology enrichment analysis identified the phototransduction pathway as a key mediator of CS’s therapeutic effects. This was further supported by reverse transcription quantitative polymerase chain reaction validation of critical genes and immunofluorescence staining, which confirmed the restored expression of Pde6a and Gnat2, key proteins involved in photic signal transmission. Active component screening indicated that high-polar constituents, including chlorogenic acid, may constitute one of the major bioactive fractions responsible for the observed therapeutic effects. Conclusion: This study provides evidence of the vision-protective effects of CS in a zebrafish model, demonstrating that its therapeutic mechanism involves modulation of the phototransduction pathway. Chlorogenic acid was identified as one of the key bioactive constituents contributing to this effect. These findings not only provide scientific validation for the traditional use of CS in ocular protection but also present promising therapeutic prospects for the prevention and treatment of visual impairment.

Objective To investigate the protective effect of Notch1-regulated microglial polarization against epileptic seizure in mice.Methods The pentylenetetrazole(PTZ)kindling models of epilepsy were established in mice with normal(Notch1normal)and high(Notch1over)expression of the Notch1 protein,with Racine grade Ⅳ set as the standard,to evaluate the effect of Notch1 expression on sei-zure susceptibility.Microglial activation and polarization in the temporal lobe tissues of mice were detected using immunofluorescence staining,and the levels of inflammatory cytokines in the temporal lobe tissues was detected using an enzyme-linked immunosorbent assay.Results High Notch1 expression showed high resistance to seizures.Compared with the Notch1normal+Sal group,the relative fluorescence intensity of Iba1,CD16,and Arg1 proteins in the temporal lobes of mice in the Notch1normal+PTZ group,as well as the TNF-α,IL-6,and IL-10 levels significantly increased(P＜0.05).Compared with the Notch1nornal+PTZ group,the relative fluorescence intensity of Iba1 and CD16 proteins in the temporal lobes of mice in the Notch1over+PTZ group significantly decreased(P＜0.05),the relative fluorescence intensity of Arg1 protein significantly increased(P＜0.05),the TNF-α and IL-6 levels significantly decreased(P＜0.05),and the IL-10 level further increased(P＜0.05).Conclusion High Notch1 protein expression significantly enhanced M2-type microglial polari-zation,inhibited M1-type microglial polarization,and increased resistance to seizure susceptibility in mice.

Lonicerae Japonicae Flos is a significant food and traditional Chinese medicine, known as plant antibiotics. It has rich chemical constituents and significant pharmacological effects. The antitumor activity of Lonicerae Japonicae Flos has been clarified, but the study on its spectrum-effect relationship has not been reported. The compounds responsible for its antitumor activity are still unknown. In this study, processed products of Lonicerae Japonicae Flos at different temperatures were taken as experimental materials, and SMMC-7721, A549, and MGC80-3 cells were tested. The orthogonal partial least squares regression method was used to analyze the common compounds in different processed products and the antitumor activity. The results show that processed products have a stronger inhibitory effect on A549 cells and MGC80-3 cells than SMMC-7721 cells. Compounds such as secologanic acid, isochlorogenic acid A, serotonin, and chlorogenic acid play an important role in their antitumor effects.

Lilii Bulbus is a commonly used Chinese herbal medicine with both medicinal and edible values, while the market products usually has the problem of sulfur fumigation. Therefore, the quality and safety of Lilii Bulbus products deserve attention. In this study, ultra-high performance liquid chromatography-time of flight-tandem mass spectrometry(UPLC-Q-TOF-MS/MS) was combined with principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) to analyze the differential components of Lilii Bulbus before and after sulfur fumigation. We identified ten markers generated after sulfur fumigation, summarized their mass fragmentation and transformation patterns, and verified the structures of phenylacrylic acid markers of sulfur fumigation. At the same time, the cytotoxicity of the aqueous extracts of Lilii Bulbus before and after sulfur fumigation was evaluated. The results showed that in the concentration range of 0-800 mg·L~(-1), the aqueous extract of Lilii Bulbus after sulfur fumigation had no significant effect on the viability of human liver LO2 cells, human renal proximal tubular HK-2 cells, and rat adrenal pheochromocytoma PC-12 cells. Moreover, the viability of the cells exposed to the aqueous extract of Lilii Bulbus before and after sulfur fumigation showed no significant difference. This study identified phenylacrylic acid and furostanol saponins as markers of sulfur-fumigated Lilii Bulbus for the first time, and made clear that proper sulfur fumigation of Lilii Bulbus would not produce cytotoxicity, providing a theoretical basis for the rapid identification and quality and safety control of sulfur-fumigated Lilii Bulbus.

Objective:To explore the feasibility of replacing wood （or wood chips） with crop residues for culturing Armillaria gallica targeting the problems of forest resource destruction and increased cultivation cost caused by the extensive use of wood in Gastrodia elata cultivation， so as to reduce the cultivation cost of G. elata， promote the effective use of crop residues， and protect forest resources. Method:The growth situation of A. gallica in different media was observed， followed by the measurement of its growth rate using streaking method and the determination of total polysaccharide content of A. gallica by phenol-concentrated sulfuric acid colorimetric method. In order to further optimize the soybean straw cultivation medium， we carried out a four-factor three-level L₉（3⁴） orthogonal assay on the ratio of main ingredients， sucrose content， inorganic salt content， and water content. Result:The comparison of growing states of A. gallica cultured in different media revealed that A. gallica in soybean straw medium began to grow since the fourth day of inoculation， and the mycelium grew well， with the growth rate being 0.352 cm·d^-1， which was 1.48 times that in birch wood medium. The total polysaccharide content of A. gallica cultured in soybean straw medium was the highest， which was 39.260 mg·g^-1， much higher than 17.028 mg·g^-1 of that cultured in birch wood medium. This demonstrated the obvious advantage of soybean straw medium， whose main ingredients were soybean straw and wheat bran at the ratio of 8：2， with the sucrose and inorganic salt content accounting for 1% and 0.5% of the main ingredients， respectively. When the water content reached 50%， the growth rate of A. gallica was maintained at 0.392 cm·d^-1. Conclusion:This study has provided a basis for utilizing soybean straw instead of wood （or wood chips） as cultivation medium for A. gallica， thus better reducing the waste of forest resources and protecting the natural environment in the cultivation of G. elata.
