		                        			As people’s attention to health continues to increase, the market demand for traditional Chinese medicine (TCM) is growing steadily. The quality and safety of Chinese medicinal materials have attracted unprecedented social attention. In particular, the issue of exogenous harmful residue pollution in TCM has become a hot topic of concern for both regulatory authorities and society. The Chinese Pharmacopoeia 2025 Edition further refines the detection methods and limit standards for exogenous harmful residues in TCM. This not only reflects China’s high-level emphasis on the quality and safety of TCM but also demonstrates the continuous progress made by China in the field of TCM safety supervision. Basis on this study, by systematically reviewing the development history of the detection standards for exogenous harmful residues in TCM and analyzing the revisions and updates of these detection standards in the Chinese Pharmacopoeia 2025 Edition, deeply explores the key points of the changes in the monitoring standards for exogenous harmful residues in TCM in the Chinese Pharmacopoeia 2025 Edition. Moreover, it interprets the future development directions of the detection of exogenous residues in TCM, aiming to provide a reference for the formulation of TCM safety supervision policies.

		                        			ObjectiveTo observe the effects of Tongluo Baoshen prescription (TLBS)-containing serum on the rat podocyte injury induced by lipopolysaccharide (LPS) and explore the potential mechanisms. MethodsSD rats were used to prepare the blank serum, losartan potassium-containing serum, and low-, medium-, and high-dose TLBS-containing sera. Rat podocytes were cultured in vitro, and the effects of drug-containing sera on podocyte viability were detected by the cell counting kit-8 (CKK-8) method. The optimal intervention volume fraction of drug-containing sera and the optimal concentration of LPS for inducing the podocyte injury were determined. Rat podocytes were grouped as follows: normal control (NC, 10% blank serum), model control (MC, 20.00 mg·L-1 LPS+10% black serum), losartan potassium (LP, 20.00 mg·L-1 LPS+10% losartan potassium-containing serum), low-dose TLBS (TLBS-L, 20.00 mg·L-1 LPS+10% low-dose TLBS-containing serum), medium-dose TLBS (TLBS-M, 20.00 mg·L-1 LPS+10% medium-dose TLBS-containing serum), and high-dose TLBS (TLBS-H, 20.00 mg·L-1 LPS+10% high-dose TLBS-containing serum), and the interventions lasted for 48 h. The ultrastructure of podocytes was observed under a transmission electron microscope. The podocyte apoptosis was detected by the terminal deoxynucleoitidyl transferase mediated nick-end labeling (TUNEL) kit. Immunofluorescence was used to detect the expression of gasdermin D N-terminal fragment (GSDMD-NT) in podocytes. The mRNA and protein levels of G protein-coupled receptor family C group 5 member B (GPRC5B), nuclear factor-κB (NF-κB) p50, NF-κB p52, NF-κB p65, Rel B, c-Rel, NOD-like receptor protein 3 (NLRP3), cysteinyl aspartate-specific protease-1 (Caspase-1), GSDMD-NT, interleukin (IL)-1β, IL-18, nephrin, integrin α3, and integrin β1 in podocytes were determined by real-time quaritiative polymerase chain reaction (Real-time PCR) and Western blot, respectively. ResultsCompared with the NC group, the MC group showed reduced podocyte protrusions and organelles, segmental missing of cell membranes, increased and swollen mitochondria, irregular nuclear membranes, light chromatin, increased TUNEL fluorescence-positive nuclei (P<0.01), obviously enhanced fluorescence intensity of GSDMD-NT, up-regulated mRNA and protein levels of GPRC5B, NF-κB p50, NF-κB p52, NF-κB p65, Rel B, c-Rel, NLRP3, caspase-1, GSDMD-NT, IL-1β, and IL-18 (P<0.01), and down-regulated mRNA and protein levels of nephrin, integrin α3, and integrin β1 (P<0.01) in podocytes. Compared with the MC group, the LP, TLBS-M, and TLBS-H groups showed improved ultrastructure of podocytes with increased protrusions, intact cell membranes, reduced organelles, and alleviated mitochondrial swelling, decreased TUNEL fluorescence-positive nuclei (P<0.01), weakened fluorescence intensity of GSDMD-NT, down-regulated mRNA and protein levels of GPRC5B, NF-κB p50, NF-κB p52, NF-κB p65, Rel B, c-Rel, NLRP3, caspase-1, GSDMD-NT, IL-1β, and IL-18 (P<0.01), and up-regulated mRNA and protein levels of nephrin, integrin α3, and integrin β1 (P<0.05, P<0.01). Moreover, the changes above were the most obvious in the TLBS-H group. ConclusionThe TLBS-containing serum can regulate the GPRC5B/NF-κB/NLRP3 pathway to inhibit pyroptosis, thereby ameliorating the podocyte injury induced by LPS.

		                        			ObjectiveTo investigate the therapeutic effect of Baihe Wuyaotang (BWT) on non-alcoholic fatty liver disease (NAFLD) and elucidate its underlying mechanism. MethodC57BL/6J mice were randomly assigned to six groups: normal control, model, positive drug (pioglitazone hydrochloride 1.95×10-3 g·kg-1), and low-, medium-, and high-dose BWT (1.3,2.5 and 5.1 g·kg-1). Following a 12-week high-fat diet (HFD) inducement, the mice underwent six weeks of therapeutic intervention with twice-daily drug administration. Body weight was monitored weekly throughout the treatment period. At the fifth week, glucose tolerance (GTT) and insulin tolerance (ITT) tests were conducted. Subsequently, the mice were euthanized for the collection of liver tissue and serum, and the subcutaneous adipose tissue (iWAT) and epididymal adipose tissue (eWAT) were weighed. Serum levels of total triglycerides (TG) and liver function indicators,such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), were determined. Histological examinations, including oil red O staining, hematoxylin-eosin (HE) staining, Masson staining, and transmission electron microscopy, were performed to evaluate hepatic lipid deposition, pathological morphology, and ultrastructural changes, respectively. Meanwhile, Western blot and real-time quantitative polymerase chain reaction (Real-time PCR) were employed to analyze alterations, at both gene and protein levels, the insulin signaling pathway molecules, including insulin receptor substrate 1/2/protein kinase B/forkhead box gene O1 (IRS1/2/Akt/FoxO1), glycogen synthesis enzymes phosphoenolpyruvate carboxy kinase (Pepck) and glucose-6-phosphatase (G6Pase), lipid metabolism-related genes stearoyl-coA desaturase-1 (SCD-1) and carnitine palmitoyltransferase-1 (CPT-1), fibrosis-associated molecules α-smooth muscle actin (α-SMA), type Ⅰ collagen (CollagenⅠ), and the fibrosis canonical signaling pathway transforming growth factor-β1/drosophila mothers against decapentaplegic protein2/3(TGF-β1/p-Smad/Smad2/3), inflammatory factors such as interleukin(IL)-6, IL-8, IL-11, and IL-1β, autophagy markers LC3B Ⅱ/Ⅰ and p62/SQSTM1, and the expression of mammalian target of rapamycin (mTOR). ResultCompared with the model group, BWT reduced the body weight and liver weight of NAFLD mice(P<0.05, P<0.01), inhibited liver lipid accumulation, and reduced the weight of white fat: it reduced the weight of eWAT and iWAT(P<0.05, P<0.01) as well as the serum TG content(P<0.05, P<0.01). BWT improved the liver function as reflected by the reduced ALT and AST content(P<0.05, P<0.01). It improved liver insulin resistance by upregulating IRS2, p-Akt/Akt, p-FoxO1/FoxO1 expressions(P<0.05). Besides, it improved glucose and lipid metabolism disorders: it reduced fasting blood glucose and postprandial blood glucose(P<0.05, P<0.01), improved GTT and ITT(P<0.05, P<0.01), reduced the expression of Pepck, G6Pase, and SCD-1(P<0.01), and increased the expression of CPT-1(P<0.01). The expressions of α-SMA, Collagen1, and TGF-β1 proteins were down-regulated(P<0.05, P<0.01), while the expression of p-Smad/Smad2/3 was downregulated(P<0.05), suggesting BWT reduced liver fibrosis. BWT inhibited inflammation-related factors as it reduced the gene expression of IL-6, IL-8, IL-11 and IL-1β(P<0.01) and it enhanced autophagy by upregulating LC3B Ⅱ/Ⅰ expression(P<0.05)while downregulating the expression of p62/SQSTM1 and mTOR(P<0.05). ConclusionBWT ameliorates NAFLD by multifaceted improvements, including improving IR and glucose and lipid metabolism, anti-inflammation, anti-fibrosis, and enhancing autophagy. In particular, BWT may enhance liver autophagy by inhibiting the mTOR-mediated signaling pathway.

		                        			ObjectiveTo explore the possible mechanism of Osteoking (OK) on postmenopausal osteoporosis (PMOP). MethodForty adult female mice were randomly divided into a sham operation (Sham) group, osteoporosis model (OVX) group, estradiol intervention (E2) group, and OK group, with 10 mice in each group. The modeling was completed by conventional back double incision ovariectomy, and the corresponding drugs were given one week later. After 12 weeks, the body mass and uterine index of mice were measured, and the pathological changes of bone tissue and the number of osteoclasts (OCs) were determined by hematoxylin-eosin (HE) and tartrate-resistant acid phosphatase (TRAP) staining, respectively. Bone mineral density (BMD), trabecular number (Tb.N), trabecular separation (Tb.Sp), and bone volume fraction (BV/TV) were measured by microcomputed tomography (Micro-CT). The maximum load of the femur was detected by a three-point bending test. The contents of tumor necrosis factor-α (TNF-α) and bone resorption marker C-terminal telopeptide of type Ⅰ collagen (CTX-1) were measured by enzyme linked immunosorbent assay (ELISA). The protein expression levels of nuclear factor-kappa B p65 (NF-κB p65), phosphorylated nuclear factor-kappa B p65 (p-NF-κB p65), nuclear factor kappa B inhibitor alpha (IκBα), phosphorylated nuclear factor kappa B alpha (p-IκBα), nuclear factor of activated T cells 1 (NFATc1), and proto-oncogene (c-Fos) were detected by Western blot. The mRNA expressions of OCs-related specific genes matrix metalloproteinase-9 (MMP-9), NFATc1, TRAP, cathepsin K (CTSK), and c-Fos were detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). ResultCompared with the Sham group, the uterine index decreased significantly in the OVX group, and the body mass (BMI) increased significantly. The structure of bone trabeculae was completely damaged, and the number of OCs increased. BMD, Tb.N, BV/TV, and maximum load decreased, while Tb.Sp was up-regulated. The levels of TNF-α and CTX-1 in serum were up-regulated. The protein expressions of c-Fos, p-NF-κB p65/NF-κB p65, NFATc1, and p-IκBα/IκBα were increased. The mRNA expressions of NFATc1, c-Fos, CTSK, TRAP, and MMP-9 were up-regulated (P<0.05, P<0.01). Compared with the OVX group, the body mass of the OK and E2 groups decreased, and the uterine index increased. The bone trabeculae increased, and the number of OCs decreased. BMD, Tb.N, BV/TV, and maximum load increased, while Tb.Sp decreased. The levels of TNF-α and CTX-1 in serum were decreased. The protein expressions of c-Fos, p-NF-κB p65/NF-κB p65, NFATc1, and p-IκBα/IκBα were decreased, and the mRNA expressions of NFATc1, c-Fos, CTSK, TRAP, and MMP-9 were decreased (P<0.05, P<0.01). ConclusionOK can inhibit the NF-κB/NFATc1 signaling pathway and reduce bone mass loss by reducing the level of inflammatory injury factors in PMOP mice, which is one of the mechanisms for treating PMOP.

		                        			IgA nephropathy is recognized as the most common primary glomerular disease, with up to 20%-40% of patients developing end-stage kidney disease within 20 years of onset. The deposition of IgA1-containing immune complexes targeting glycosylation defects in the mesangial region and the subsequent inflammation caused by T lymphocyte activation are considered as the main causes of IgA nephropathy, and innate immunity is also involved in the pathogenesis. Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a newly discovered pattern recognition receptor expressed in renal intrinsic cells such as renal tubular epithelial cells, mesangial cells, and podocytes. Activated by external stimuli, NLRP3 can form NLRP3 inflammasomes with apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC). The NLRP3 inflammasome can activate cysteine aspartate-specific protease-1 (Caspase-1), causing the maturation and release of interleukin-18 (IL-18) and interleukin-1β (IL-1β) involved in inflammation. Increasing evidence has suggested that NLRP3 inflammasomes are involved in the pathogenesis and progression of IgA nephropathy and associated with the damage of renal intrinsic cells such as podocytes, mesangial cells, endothelial cells, and renal tubular epithelial cells. Chinese medicine can regulate inflammatory cytokines and their signaling pathways by acting on NLRP3 inflammasomes and related molecules, exerting therapeutic effects on IgA nephropathy. This article introduces the role of NLRP3 inflammasomes in IgA nephropathy and reviews the clinical and experimental research progress of Chinese medicine intervention in IgA nephropathy via NLRP3 inflammasomes, aiming to provide a reference for further research and application of Chinese medicine intervention in the NLRP3 inflammasome as a new therapeutic target.

		                        			To explore the neuroprotective effects of the Shaoyao Gancao decoction (SGD) against excitatory damage in PC12 cells and the role of the Src-NR2-nNOS pathway mediation by SGD in regulating γ-aminobutyric acid (GABA)-glutamate (Glu) homeostasis.
		                        		
		                        			Methods:
		                        			N-Methyl-d-aspartic acid (NMDA) was used to establish a PC12 cell excitability injury model. To investigate the neuroprotective effect of SGD, a cell counting kit-8 (CCK-8) assay was used to determine PC12 cell viability, Annexin V/Propidium Iodide (Annexin V/PI) double staining was used to determine PC12 cell apoptosis, and Ca2+ concentration was observed using laser confocal microscopy. GABA receptor agonists and antagonists were used to analyze the neuroprotective interactions between γ-aminobutyric acid (GABA) and NMDA receptors. Additionally, molecular biology techniques were used to determine mRNA and protein expression in the Src-NR2-nNOS pathway. We analyzed the correlations between the regulatory sites of GABA and NMDA interactions, excitatory neurotoxicity, and brain damage at the molecular level.
		                        		
		                        			Results:
		                        			NMDA excitotoxic injury manifested as a significant decrease in cell activity, increased apoptosis and caspase-3 protein expression, and a significant increase in intracellular Ca2+ concentration. Administration of SGD, a GABAA receptor agonist (muscimol), or a GABAB receptor agonist (baclofen) decreased intracellular Ca2+ concentrations, attenuated apoptosis, and reversed NMDA-induced upregulation of caspase-3, Src, NMDAR2A, NMDAR2B, and nNOS. Unexpectedly, a GABAA receptor antagonist (bicuculline) and a GABAB receptor antagonist (saclofen) failed to significantly increase excitatory neurotoxicity.
		                        		
		                        			Conclusions
		                        			Taken together, these results not only provide an experimental basis for SGD administration in the clinical treatment of central nervous system injury diseases, but also suggest that the Src-NR2A-nNOS pathway may be a valuable target in excitotoxicity treatment.

		                        			ObjectiveTo observe the effect of deep muscle stimulation on muscle structure and function in children with spastic cerebral palsy. MethodsFrom January, 2023 to March, 2024, 30 children with spastic cerebral palsy in Beijing Bo'ai Hospital were randomly divided into control group (n = 15) and intervention group (n = 15). Both groups received conventional rehabilitation therapy, while the intervention group added deep muscle stimulation, for four weeks. Before and after training, the gastrocnemius muscle was examined by ultrasound diagnosis system in two aspects: transverse incision and longitudinal incision. Indicators included fascicle length, muscular thickness, cross sectional area and pennation angle. The modified Ashworth Scale (MAS) was used to assess the muscle tension of the lower extremity of the affected side. The standing, walking, running and jumping function were evaluated by Gross Motor Function Measure (GMFM) D and E areas. ResultsAfter training, the fascicule length and pennation angle improved significantly in both groups (|t| > 6.329, P < 0.001), and they were better in the intervention group than in the control group (|t| > 2.347, P < 0.05); the scores of MAS decreased in both groups (t > 2.432, P < 0.05), and were better in the intervention group than in the control group (t = 2.140, P < 0.05); the scores of GMFM D and E areas significantly decreased in both groups (|t| > 8.473, P < 0.001), and were better in the intervention group than in the control group (|t| > 2.191, P < 0.05). ConclusionDeep muscle stimulation could improve the fascicule length and pennation angle, and improve the spasticity and motor function of lower extremities in children with spastic cerebral palsy.
