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.

This study investigated the therapeutic effects and mechanisms of Modified Yiyi Fuzi Baijiang Powder on ulcerative colitis(UC) in rats from the perspective of dampness. SD rats were randomly allocated into six groups(n=10): control, model, mesalazine, and Modified Yiyi Fuzi Baijiang Powder at low(3.96 g·kg~(-1)·d~(-1)), medium(7.92 g·kg~(-1)·d~(-1)), and high(15.84 g·kg~(-1)·d~(-1)) doses. UC was induced in all groups except the control by administration with 3% dextran sulfate sodium(DSS) solution for 7 days. The disease activity index(DAI) was recorded, and the colon tissue was collected for analysis. Histopathological changes were assessed by hematoxylin-eosin staining. Serum levels of D-lactic acid(D-LA) and diamine oxidase(DAO) were measured by ELISA. Immunohistochemistry and PCR were employed to evaluate the expression of aquaporins(AQP3, AQP4) and tight junction proteins [zonula occludens-1(ZO-1) and occludin] at both protein and mRNA levels. Compared with the control group, the model group showed an increased DAI scores(P<0.05), intestinal mucosal damage, elevated serum levels of DAO and D-LA(P<0.05), and decreased expression of AQP3, AQP4, ZO-1, and occludin(P<0.05). Treatment with Modified Yiyi Fuzi Baijiang Powder reduced the DAI scores(P<0.05), lowered the serum levels of D-LA and DAO(P<0.05), and upregulated the expression of AQP3, AQP4, ZO-1, and occludin at both protein and mRNA levels compared with the model group. These findings suggest that Modified Yiyi Fuzi Baijiang Powder exerts therapeutic effects on UC by reducing the intestinal mucosal permeability, promoting colonic mucosal repair, and regulating abnormal intestinal water metabolism, which may involve the upregulation of AQP3 and AQP4 expression.

Fritillariae Cirrhosae Bulbus is the dried bulb of perennial herbaceous plants in the Fritillaria genus(Liliaceae family) and is a representative traditional Chinese medicinal material with distinctive regional characteristics. Clinically, it is widely used in the treatment of dry cough, bronchial asthma, and other respiratory diseases, possessing significant medicinal and economic value and being highly esteemed in TCM. Currently, Fritillariae Cirrhosae Bulbus primarily relies on wild harvesting. However, due to excessive collection, its wild resources have drastically declined, and all source species have been classified as category Ⅱ in the List of National Key Protected Wild Plants, exacerbating the supply-demand imbalance in the market. To mitigate this issue, large-scale cultivation through the domestication of wild Fritillariae Cirrhosae Bulbus has become an inevitable trend. However, its strict environmental requirements, low propagation efficiency, high seedling mortality, and immature cultivation techniques have severely hindered industrialization. This study investigates the domestication process of Fritillariae Cirrhosae Bulbus, focusing on seed propagation, seedling cultivation, and medicinal material production. It also reviews the species and distribution of wild resources, their endangered status, market supply-demand dynamics, and the historical and current development of domestication. The findings indicate that enhancing propagation efficiency, optimizing cultivation models, and distinguishing between seed propagation and medicinal material production are key measures to accelerate the industrialization of domesticated Fritillariae Cirrhosae Bulbus. This research aims to promote the industrialization of Fritillariae Cirrhosae Bulbus domestication and provide a reference model for the conservation and sustainable utilization of rare and endangered medicinal plant resources.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

ObjectiveTo investigate the mechanism by which Huanglian Jiedutang (HLJDT) inhibits pyroptosis and neuroinflammation in Alzheimer's disease (AD) mice via the NOD-like receptor protein 3 (NLRP3)/cysteinyl aspartate-specific protease-1 (Caspase)-1/gasdermin D (GSDMD) pathway. MethodsThirty APP/PS1 double transgenic mice were randomly and evenly divided into the model group (model group), the positive control group (Donepezil group, 0.65 mg·kg-1), and the HLJDT treatment group (HLJDT group, 5.2 g·kg-1). Ten C57BL/6 mice were assigned to the blank control group (control group). The Morris water maze and novel object recognition tests were used to evaluate learning and memory abilities. Nissl staining was employed to observe the morphology, quantity, and distribution of neurons in the hippocampal region. Golgi staining was used to examine the morphology and density of neuronal dendritic spines in the hippocampus. Real-time quantitative polymerase chain reaction (Real-time PCR) was performed to detect the mRNA expression of neuroinflammation-related factors and genes in the NLRP3/Caspase-1/GSDMD pyroptosis pathway in the hippocampus. Western blot was used to detect the expression of postsynaptic density protein 95 (PSD95), amyloid precursor protein (APP), inflammatory factors including nuclear factor-κB (NF-κB), phosphorylated NF-κB (p-NF-κB), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), as well as pyroptosis pathway-related proteins including NLRP3, Caspase-1, GSDMD, and GSDMD-N. ResultsCompared with the control group, the model group exhibited significantly decreased learning and memory abilities (P<0.01), reduced numbers of neurons in the hippocampal CA3 region and dendritic spines in the hippocampal CA1 region (P<0.01), and significantly increased hippocampal mRNA expression levels of NLRP3, Caspase-1, GSDMD, NF-κB, TNF-α, IL-1β, and IL-18 (P<0.01). Protein levels of PSD95 were markedly decreased, while the expression levels of NLRP3, Caspase-1, GSDMD, p-NF-κB/NF-κB, TNF-α, IL-1β, and APP were significantly elevated (P<0.01). Compared with the model group, both the Donepezil and HLJDT groups showed significantly improved learning and memory abilities (P<0.05, P<0.01), increased numbers of hippocampal neurons in the hippocampal CA3 region and dendritic spines in the hippocampal CA1 region (P<0.01), and significantly decreased hippocampal mRNA expression levels of NLRP3, Caspase-1, GSDMD, NF-κB, TNF-α, IL-1β, and IL-18 (P<0.05, P<0.01). Protein levels of NLRP3, Caspase-1, GSDMD, p-NF-κB/NF-κB, TNF-α, IL-1β, and APP were significantly downregulated, while PSD95 expression was significantly upregulated (P<0.05, P<0.01). There was no statistically significant difference in GSDMD-N levels in the Donepezil group, while GSDMD-N expression was significantly decreased in the HLJDT group (P<0.05). ConclusionThis study confirms that HLJDT can improve learning and memory abilities in APP/PS1 double transgenic mice, and attenuate neuronal loss and synaptic damage, possibly through inhibition of pyroptosis via the NLRP3/Caspase-1/GSDMD pathway.

OBJECTIVE:
To compare the clinical efficacy of jingjin needling combined with rehabilitation training and conventional acupuncture combined with rehabilitation training for post-stroke spastic paralysis.
METHODS:
A total of 60 patients with post-stroke spastic paralysis were randomly divided into an observation group and a control group, 30 cases in each one. Both groups received conventional rehabilitation training. In the observation group, jingjin needling was applied at tendon blockage points of the shoulder, elbow, wrist, hip, knee, and ankle. In the control group, conventional acupuncture was applied at Jianyu (LI15), Quchi (LI11), Hegu (LI4), Biguan (ST31), Fengshi (GB31), Taichong (LR3), etc. on the affected side. Treatment was given once daily, 5 days a week for 4 weeks in both groups. The scores of clinical spasticity index (CSI), modified Ashworth scale, modified Barthel index (MBI), and Fugl-Meyer assessment scale (FMA) were evaluated before and after treatment, and the onset time was compared between the two groups.
RESULTS:
After treatment, the scores of CSI and modified Ashworth scale were decreased compared with those before treatment (P<0.001), while the scores of MBI and FMA were increased compared with those before treatment (P<0.001) in the two groups. After treatment, the scores of CSI and modified Ashworth scale in the observation group were lower than those in the control group (P<0.05), the MBI score in the observation group was higher than that in the control group (P<0.05). There was no statistically significant difference in FMA scores between the two groups (P>0.05). The onset time of the observation group was earlier than that in the control group (P<0.05).
CONCLUSION
Both jingjin needling combined with rehabilitation training and conventional acupuncture combined with rehabilitation training can effectively treat post-stroke spastic paralysis, jingjin needling combined with rehabilitation training exhibits better therapeutic effect and rapider onset.

This study aims to explore the effects and mechanisms of the traditional Chinese medicine Cordyceps sinensis(CS) in ameliorating heart aging and injury in mice based on animal experiments and network pharmacology. A mouse model of heart aging was established by continuously subcutaneous injection of D-galactose(D-gal). Thirty mice were randomly assigned into a normal group, a model group, a low-dose CS(CS-L) group, a high-dose CS(CS-H) group, and a vitamin E(VE) group. Mice in these groups were administrated with normal saline, different doses of CS suspension, or VE suspension via gavage daily. After 60 days of treatment with D-gal and various drugs, all mice were euthanized, and blood and heart tissue samples were collected for determination of the indicators related to heart aging and injury in mice. Experimental results showed that both high and low doses of CS and VE ameliorated the aging phenotype, improved the heart index and myocardial enzyme spectrum, restored the expression levels of proteins associated with cell cycle arrest and senescence-associated secretory phenotypes(SASP), and alleviated the fibrosis and histopathological changes of the heart tissue in model mice. From the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),259 active ingredients of CS were retrieved. From Gene Cards and OMIM, 2 568 targets related to heart aging were identified, and 133common targets shared by CS and heart aging were obtained. The Gene Ontology(GO) functional annotation and Kyoto Encyclopedia of Genes and Genomes( KEGG) pathway enrichment revealed that the pathways related to heart aging involved oxidative stress,apoptosis, inflammation-related signaling pathways, etc. The animal experiment results showed that both high and low doses of CS and VE ameliorated oxidative stress and apoptosis in the heart tissue to varying degrees in model mice. Additionally, CS-H and VE activated the nuclear factor E2-related factor 2(Nrf2)/heme oxygenase-1(HO-1) pathway and inhibited the expression of key proteins in the nuclear factor-κB(NF-κB) pathway in the heart tissue of model mice. In conclusion, this study demonstrated based on network pharmacology and animal experiments that CS may alleviate heart aging and injury in aging mice by reducing oxidative stress,apoptosis, and inflammation in the heart via the Nrf2/HO-1/NF-κB pathway.
