At present, the cause of traditional Chinese medicine(TCM) in China has entered a new period of high-quality development. How to strengthen the foundation for the TCM industry from the source is an important issue that deserves the attention of the authorities, industry, and academia. This study systematically analyzed the regulatory system of TCM raw materials and preparations. The study took the TCM industry chain and the product life cycle as a clue and focused on the dimensions of TCM resource protection and plant cultivation(farming), production and quality supervision of TCM raw materials and preparations, and their market access and distribution. It analyzed the current situation of the regulation of TCM raw materials and preparations under the regulatory system of drugs, discussed the main problems, and put forward corresponding suggestions. The results can provide an important reference value for the subsequent improvement of the regulatory system of drugs and the construction of a prominent regulatory system of drugs in accordance with TCM characteristics.

This study employed bioinformatics to screen the feature genes related to efferocytosis in diabetic kidney disease(DKD) and explores traditional Chinese medicine(TCM) regulating these feature genes. The GSE96804 and GSE30528 datasets were integrated as the training set, and the intersection of differentially expressed genes and efferocytosis-related genes(ERGs) was identified as DKD-ERGs. Subsequently, correlation analysis, protein-protein interaction(PPI) network construction, enrichment analysis, and immune infiltration analysis were performed. Consensus clustering was conducted on DKD patients based on the expression levels of DKD-ERGs, and the expression levels, immune infiltration characteristics, and gene set variations between different subtypes were explored. Eight machine learning models were constructed and their prediction performance was evaluated. The best-performing model was evaluated by nomograms, calibration curves, and external datasets, followed by the identification of efferocytosis-related feature genes associated with DKD. Finally, potential TCMs that can regulate these feature genes were predicted. The results showed that the training set contained 640 differentially expressed genes, and after intersecting with ERGs, 12 DKD-ERGs were obtained, which demonstrated mutual regulation and immune modulation effects. Consensus clustering divided DKD into two subtypes, C1 and C2. The support vector machine(SVM) model had the best performance, predicting that growth arrest-specific protein 6(GAS6), S100 calcium-binding protein A9(S100A9), C-X3-C motif chemokine ligand 1(CX3CL1), 5'-nucleotidase(NT5E), and interleukin 33(IL33) were the feature genes of DKD. Potential TCMs with therapeutic effects included Astragali Radix, Trionycis Carapax, Sargassum, Rhei Radix et Rhizoma, Curcumae Radix, and Alismatis Rhizoma, which mainly function to clear heat, replenish deficiency, activate blood, resolve stasis, and promote urination and drain dampness. Molecular docking revealed that the key components of these TCMs, including β-sitosterol, quercetin, and sitosterol, exhibited good binding activity with the five target genes. These results indicated that efferocytosis played a crucial role in the development and progression of DKD. The feature genes closely related to both DKD and efferocytosis, such as GAS6, S100A9, CX3CL1, NT5E, and IL33, were identified. TCMs such as Astragali Radix, Trionycis Carapa, Sargassum, Rhei Radix et Rhizoma, Curcumae Radix, and Alismatis Rhizoma may provide a new therapeutic strategy for DKD by regulating efferocytosis.

OBJECTIVE:
To investigate the effects of Bushen Huoxue Granule on the ubiquitin-proteasome system (UPS) in an in vitro model of Parkinson's disease.
METHODS:
After treated with 1-methyl-4-phenylpyridinium (MPP+, 1 mmol/L) for 24 h, the cells were incubated with drug-free serum, Madopar-containing serum or Bushen Huoxue Granule-containing serum (BCS, 5%, 10%, and 20%) for another 24 h. The levels of α-synuclein (α-syn), tyrosine hydroxylase (TH) and UPS-related proteins were detected by Western blot. The expression levels of α-syn in PC12 cells were also analyzed by Western blot after treated with proteasome inhibitor MG132 and WT-α-syn plasmid transfection, respectively, as well as the alterations induced by subsequent BCS intervention. Immunocytochemistry was performed to determine the changes in α-syn phosphorylation at serine 129 (pSer129-α-syn) expression. The 20S proteasome levels were measured by enzyme-linked immunosorbnent assay.
RESULTS:
BCS (volume fraction ⩽20%) intervention could alleviate the MMP+-induced cell viability decrease (P<0.05). In the MPP+ treated cells, α-syn was up-regulated, while TH and proteins of UPS such as ubiquitin (Ub), Ub binding with Ub-activating enzyme (UBE1), Parkin and Ub C-terminal hydrolase-1 (UCHL-1) were down-regulated (P<0.05). BCS intervention could attenuate the above changes (P<0.05). The activity of BCS on blocking α-syn accumulation was weakened by MG132 (P<0.05). While α-syn level was significantly increased in cells transfected with plasmid, and reduced by BCS intervention (P<0.05). pSer129-α-syn was increased in MPP+-induced PC12 cells, whereas decreased by later BCS intervention (P<0.05). The 20S proteasome activity of MPP+-induced PC12 cells was decreased, but increased after BCS intervention (P<0.05).
CONCLUSION
BCS intervention protected UPS function, increased 20S proteasome activity, promoted pathological α-syn clearance, restored cell viability, and reversed the damage caused by MPP+ in the in vitro model of Parkinson's disease.

ObjectiveTo construct an animal model of respiratory syncytial virus(RSV)-infected pneumonia suitable for preclinical studies. MethodsThe virulence of RSV to the four cell lines was observed by cytopathic effect (CPE), and 50% tissue culture infective dose(TCID50) was calculated. Twenty BALB/c mice were randomly divided into a normal group and a model group. Six BALB/c-hIGF1R mice served as the humanized IGF1R model group. Except for the normal group, the other groups received intranasal RSV infection on days 1 and 3 to establish a viral pneumonia model. The efficacy of establishing an RSV-induced pneumonia animal model based on humanized insulin-like growth factor 1 receptor (IGF1R) mice was evaluated by measuring organ indices, peripheral blood lymphocyte percentages, pulmonary pathology and imaging, and pulmonary viral load. Additionally, ten BALB/c mice served as normal group, and thirty-two BALB/c-hIGF1R mice were randomly assigned to humanized IGF1R model group, ribavirin group (82.5 mg·kg-¹·d-¹), and high and low dose groups of Lianhua Qingwen (3.3 mg·kg-¹·d-¹ , 1.65 mg·kg-¹·d-¹), with 8 mice per group. The viral load in lung tissue was measured after ribavirin and Lianhua Qingwen intervention, and the model was applied to the evaluation of anti-RSV drugs. ResultsIn the lungs of the humanized IGF1R model group, large solid and diffuse ground-glass shadows were seen, and the lung volume was significantly increased (P<0.01). The lung index was significantly increased (P<0.01), and both the spleen index and thymus index were significantly decreased (P<0.01). The percentages of CD3+ and CD4+T cells were significantly decreased (P<0.05), and there was a large amount of inflammation and stasis in the perivascular area of the lung tissue, which was predominantly characterized by lymphocytes. The endothelium of blood vessels was partially detached, with a small number of eosinophils. After infecting BALB/c-hIGF1R mice with RSV, the expression of viral nucleic acids in the lung tissue of the mice was significantly increased, with significant differences compared with the normal group (P<0.01). The expression of viral nucleic acids in the ribavirin group and the high and low dose groups of Lianhua Qingwen was significantly reduced, with significant differences compared with the normal group (P<0.01). ConclusionHumanized IGF1R mice are more susceptible to respiratory SVC, and the animal model of RSV-infected pneumonia based on humanized IGF1R mice was successfully constructed, which is suitable for the evaluation of anti-RSV drugs.

Currently, viral pneumonia (VP) presents a major challenge to global public health. Traditional Chinese medicine (TCM) prevention and treatment of VP is guided by the core concept of strengthening vital energy and eliminating pathogenic factors rather than targeting specific pathogens, alongside a holistic approach of syndrome differentiation and treatment. By summarizing the clinical syndromes of patients, the core pathogenesis was clarified to achieve individualized therapy. Animal models for disease-syndrome combination integrate the etiology and pathogenesis of VP and simulate the individualized manifestations of patients at different disease stages, providing an experimental platform for elucidating the theoretical basis of TCM in treating VP and promoting the development of effective TCM formulations. However, there are limitations in the application and promotion of disease-syndrome combination animal models due to the lack of standardization and normalization of model construction systems, which arise from diverse species selection, compound modeling methods, and multidimensional evaluation indicators. This paper systematically reviewed the recent research on animal models for disease-syndrome combination in VP from the perspective of species selection, modeling methods, evaluation indicators, and application status. Furthermore, it summarized the advantages and limitations of existing models, identifies future directions for improvement, and proposes optimization strategies. This review provides a reference for establishing standardized and normalized animal models for disease-syndrome combinations in VP, supporting the theoretical modernization of TCM in preventing and controlling emerging respiratory infectious diseases, and contributing to the development of new TCM drugs.
