Objective: To investigate the incidence, characteristics, and influencing factors of resolution discrepancies within the minipool (MP) testing model across Chinese blood station laboratories in 2024. Methods: A nationwide, multicenter, cross-sectional study was conducted, including 334 blood station laboratories that reported nucleic acid reactive data among enzyme immunoassay non-reactive samples. Of these, 296 laboratories adopted the pool resolution model, with a total of 12 536 273 samples tested. Systematic analysis was performed on resolution data, focusing on the MP-NAT reactivity rate, the pool resolution concordance rate, and the resolution discrepancy rate. Subgroup analyses were conducted based on reagent types, viral targets, and Ct values. Potential causes were further explored through laboratory surveys and re-examination of raw amplification curves. Results: In 2024, the national average MP-NAT reactivity rate was 0.15%. The overall pool resolution concordance rate was 57.86%, which showed a gradual decline as Ct values increased across all reagents. The national average resolution discrepancy rate was 0.081‱(102/12 536 273), with 17.91%(53/296) of laboratories reporting at least one discrepancy. Nine reagent types were associated with these events, exhibiting reagent-specific patterns. For Reagent A2, the predominant discrepancy was HBV reactive pools resolving as HIV (36.36%); for Reagent D1, HBV pools frequently resolved as HCV (38.89%); and for Reagent E, the most common pattern was HIV pools resolving as HBV (48.00%). These resolution discrepancies were strongly associated with high Ct values: the median pool Ct for HBV exceeded 38, while those for HCV and HIV both exceeded 40. Investigations across 16 laboratories revealed that most discrepant samples exhibited “tailing” amplification curves, with some cases linked to cross-contamination or reagent batch-specific issues. Conclusion: While the incidence of resolution discrepancies in the MP-NAT model remains low in China, variations exist across different reagents and laboratories. These discrepancies are closely associated with low viral load, reagent performance, and laboratory operational practices.

ObjectiveTo investigate the effects of Anmei Dan (AMD) on the expression of proteins in the C-X3-C motif chemokine ligand 1 (CX3CL1)/C-X3-C chemokine receptor 1 (CX3CR1) signaling pathway, hippocampal inflammation, and learning and memory in an aged sleep-deprived model. MethodsSixty aged C57 mice were randomly assigned into a control group, a model group, a melatonin group (1.3 mg·kg-1·d-1), and high-, medium-, and low-dose AMD groups (26.26, 13.13, 6.565 g·kg-1·d-1, respectively), with 10 mice per group. Continuous sleep deprivation was administered for 4 weeks through a custom-built sleep deprivation chamber. The cognitive function of mice was assessed via the Y-maze test. Histomorphological alterations in pyramidal cells of the hippocampal CA1 and DG regions were examined by hematoxylin-eosin (HE) and Nissl staining. Synaptic morphology in the hippocampus was visualized with Golgi staining. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of inflammatory cytokines interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in the hippocampal tissue as well as the level of interleukin-10 (IL-10) in the prefrontal cortex. Real-time PCR was performed to detect markers of M1-type [cluster of differentiation (CD) 86 and inducible nitric oxide synthase (iNOS)] and M2-type [CD206 and arginase 1 (Arg1)] macrophages. Western blot was employed to quantify the protein levels of CX3CL1, CX3CR1, phosphorylated nuclear factor κB p65 subunit (p-NF-κB p65), and phosphorylated p38 mitogen-activated protein kinase (p-p38 MAPK) in the hippocampus. Immunofluorescence double staining was performed to co-label CX3CR1 with ionized calcium-binding adapter molecule 1 (Iba-1) for observation of the co-localization of target proteins with microglia. ResultsCompared with the control group, the model group exhibited disrupted daily activity patterns with reduced spontaneous alternation rates (P<0.01), disorganized morphology and arrangement of hippocampal neurons, accompanied by reduced numbers of Nissl bodies and dendritic spines (P<0.01), upregulated protein levels of IL-6, IL-10, IL-1β, TNF-α, CX3CL1, CX3CR1, p-NF-κB p65, p-p38 MAPK, and Iba-1 and mRNA levels of CD86 and iNOS (P<0.01), and downregulated mRNA levels of CD206 and Arg1 (P<0.05,P<0.01). Compared with the model group, the melatonin group and medium- and high-dose AMD groups showed increased spontaneous alternation rates (P<0.01), improved neuronal morphology, number, and spine density in the hippocampal CA1 and DG regions (P<0.01), declined levels of IL-6, IL-10, IL-1β, and TNF-α (P<0.05, P<0.01), downregulated protein levels of CX3CL1, CX3CR1, p-NF-κB p65, p-p38 MAPK, and Iba-1 and mRNA levels of CD86 and iNOS, and upregulated mRNA levels of CD206 and Arg1 (P<0.01). ConclusionAMD may improve the learning and memory in aged sleep-deprived mice by mediating neuroinflammation through the CX3CL1/CX3CR1 signaling pathway.

Metabolic dysfunction-associated fatty liver disease (MAFLD) is a chronic liver disease closely related to metabolic dysfunction. Its global prevalence is increasing year by year and shows a trend toward younger onset. It is closely associated with cardiovascular and cerebrovascular diseases, chronic kidney disease, and extrahepatic malignant tumors, and has become a major public health problem affecting the health of the Chinese population. At present, the treatment of MAFLD mainly focuses on lifestyle intervention. When metabolic cardiovascular risk factors and liver injury are present, pharmacological intervention is required. However, there is still no specific drug therapy for MAFLD. In recent years, many studies have found that the pathogenesis of MAFLD involves interactions among multiple factors, including insulin resistance, oxidative stress, endoplasmic reticulum stress, programmed cell death, immune dysregulation, inflammasomes, gut microbiota imbalance, and bile acid metabolism. Traditional Chinese medicine (TCM) has advantages in integrated regulation with multiple components and multiple targets, and shows significant efficacy in the treatment of MAFLD. Active components of Chinese medicinal herbs and Chinese medicine compound formulas exert definite therapeutic effects by regulating multiple signaling pathways to improve lipid metabolism disorders, inhibit inflammatory responses, and regulate the gut microbiota, thereby effectively improving clinical symptoms and delaying the occurrence and development of MAFLD. Therefore, strengthening research on the mechanisms of action of TCM in MAFLD is of crucial importance and significance for its treatment. This article summarizes the mechanisms by which Chinese medicine monomers and compound formulas intervene in MAFLD through the regulation of related signaling pathways, based on the retrieval and analysis of relevant literature from multiple databases, with the aim of providing theoretical support and a reference basis for the clinical application of TCM in the treatment of MAFLD.

OBJECTIVE To establish population pharmacokinetic model of levetiracetam (Lev) for Chinese patients with post- stroke epilepsy (PSE), and provide reference for formulating individualized dosing regimens for Lev therapy in this specific population. METHODS Blood concentration data and clinical diagnosis and treatment information of PSE patients meeting the inclusion criteria were retrospectively collected and divided into model group and validation group at an 8∶2 ratio using a random number method. Based on the model group data, a population pharmacokinetic model was developed using nonlinear mixed-effects modeling. Internal evaluation was performed through goodness-of-fit tests and bootstrap analysis, while external validation was conducted using the validation group data. RESULTS A total of 75 blood concentration measurements from 70 PSE patients were collected, with 60 measurements from 55 patients used for model development and 15 measurements from 15 patients reserved for external validation. The final model estimated a population typical value of clearance at 2.98 L/h. Estimated glomerular filtration rate, daily dose, and homocysteine level significantly influenced clearance of Lev (P<0.01). The model demonstrated satisfactory predictive performance, as evidenced by goodness-of-fit tests, bootstrap analysis, and external validation results. CONCLUSIONS Daily dose, estimated glomerular filtration rate, and homocysteine level are identified as significant covariates influencing Lev clearance in Chinese PSE patients. When making clinical decisions, comprehensive consideration should be given to the patient’s treatment response, physiological and pathological conditions, and the occurrence of adverse reactions, etc. The dosage of Lev should be adjusted based on the results of population pharmacokinetic model.

Background Water serves as an indispensable resource for human survival and constitutes one of the primary means through which humans are exposed to environmental chemicals. Consequently, the safety of drinking water is critical to safeguarding public health. Objective To analyze the levels of the 10 metal/metalloid indicators [Al, Fe, Mn, Cu, Zn, As, Cd, Cr(VI), Pb, and Hg] in drinking water from a region of the Fuchun River Basin, and to evaluate the health risks in drinking water through oral ingestion. Methods In accordance with the national Standard Examination Method for Drinking Water – Part 2: Collection and Preservation of Water Samples (GB/T 5750-2006 and GB/T 5750-2023), a total of 2016 drinking water samples were collected from urban and rural water supply systems in a region of the Fuchun Basin from 2017 to 2024. Two batches of water samples were collected annually during the dry and wet seasons, with each batch comprising 72 samples from the urban water supply system and 54 samples from the rural water supply system. These samples were analyzed according to the Standard Examination Method for Drinking Water – Part 6: Metal and Metalloid Indicators (GB/T 5750-2006 and GB/T 5750-2023) and the results were compared with the limits specified in the Standards for Drinking Water Quality (GB 5749-2022). Health risks were evaluated using the U.S. Environmental Protection Agency (EPA) health risk assessment model. Results All tested metal/metalloid elements in the drinking water samples of the area met the national standards. The results of risk assessment showed that the non-carcinogenic risks associated with oral intake of drinking water, ranked from highest to lowest, were as follows: As>Cr(VI)>Pb>Cd>Hg>Mn>Cu>Zn>Fe>Al, with values of 4.55×10−2, 2.79×10−2, 2.06×10−2, 1.20×10−2, 4.95×10−3, 4.58×10−3, 2.85×10−3, 1.95×10−3, 1.52×10−3, and 9.21×10−4, respectively. The non-carcinogenic risk of each indicator was less than 1, which suggested no potential risk to population health. The carcinogenic risks ranked as Cr(VI)>As>Cd>Pb, with values of 4.18×10−5, 2.05×10−5, 3.85×10−6, and 2.45×10−7, respectively. The carcinogenic risks of Cr(VI), As, and Cd were between 10−6 and 10−4, which suggested an acceptable carcinogenic risk, while the carcinogenic risk of Pb was relatively negligible. Children's total non-carcinogenic/total carcinogenic risks were comparable to those of adult males, both higher than those of adult females. Additionally, rural areas exhibited higher non-carcinogenic/carcinogenic risks for Cr(VI), while those risks for As and Pb were lower than those in urban water samples, and those risks for Cd were comparable between the two. Conclusion The concentrations of the 10 metal/metalloid indicators in drinking water from the studied region in the Fuchun River Basin comply with the national standards from 2017 to 2024. There is a certain carcinogenic risk associated with oral intake of drinking water, but it is still within the acceptable range. In terms of non-carcinogenic risk, no potential threat to population health is anticipated.
