Triclosan (TCS) and triclocarban (TCC) are widely used synthetic broad-spectrum antibacterial agents that can enter the human body through the skin, gastrointestinal tract, and other pathways. More and more studies have found that exposure to TCS and TCC can affect human health, but currently, review reports on the health effects of human exposure to TCS and TCC are limited. Therefore, this study reviewed population studies on the relationship between TCS and TCC exposure and health effects by searching the PubMed database, summarized the associated health outcomes, and elucidated the biological mechanisms. A total of 56 studies were retrieved, among which cross-sectional studies (25 studies, 44.64%) and cohort studies (25 studies, 44.64%) accounted for a relatively large proportion, while case-control studies (6 studies, 10.72%) were relatively few. Studies on TCS exposure (48 studies, 85.71%) were far more prevalent than those on TCC exposure (2 studies, 3.57%). The remaining 6 studies involved both TCS and TCC exposure. The research results revealed that TCS exposure was associated with male and female abnormal reproductive functions, fetal growth restriction, abnormal behavior development in children, obesity, gestational diabetes mellitus (GDM), and immune-related diseases. Although the results of different studies show significant differences, they have indicated that exposure to TCS is a potential risk factor for these health problems. Due to the limited number of studies, the evidence for the relationship between TCC exposure and most of the aforementioned health effects is insufficient. Population studies and in vitro and in vivo studies have shown that exposure to TCS and TCC can interfere with the microbial homeostasis, the endocrine system, oxidative stress and immune function of the body, which are potential mechanisms causing adverse health effects. In the future, large-scale prospective cohort studies, as well as in vivo and in vitro studies, are still needed to further clarify the associations between TCS and TCC exposure and health effects, and to deeply explore its mechanism of action. These efforts will provide references for clarifying the human health hazards of TCS and TCC exposure and formulating targeted prevention and control strategies.

OBJECTIVE To construct a dual-verification system integrating image pre-screening and Raman spectroscopy for inpatient pharmacy unit-dose dispensing in response to the issue of recognition blind spots for drugs of “same appearance but different spectrum” by drug inspection machines. METHODS An image feature and Raman spectroscopy database, covering 296 oral medications, were established. Spectral matching was performed using a cosine similarity algorithm (decision threshold 0.95). A dual-verification system of “image pre-screening and Raman spectroscopy confirmation” was designed, and a self-controlled before-and-after study was conducted across 5 clinical wards. RESULTS The system achieved a mean recognition accuracy of 99.2% for all medications in the database, with 100% accurate identification of representative “same-appearance but different-spectrum” drugs. The average verification time per-unit in the experimental group (image recognition+Raman spectroscopy confirmation and verification) was reduced by 31.5%-43.3%, compared with the control group (image recognition+manual visual comparison with actual objects)( P <0.001). Nurses’ satisfaction scores in the dimensions of operational convenience, identification efficiency, verification confidence, and psychological stress relief in the experimental group were all significantly superior to those of the control group ( P <0.01). CONCLUSIONS The dual-verification system of “image pre-screening and Raman spectroscopy confirmation” effectively overcomes the technical limitations of conventional machine vision. It enhances work efficiency and staff satisfaction while ensuring medication safety.
3.Understanding the drivers of continuance intention in online grocery shopping using technology continuance theory: a cross-national comparison
Korean Journal of Community Nutrition 2026;31(1):50-63
Objectives:
This study examined the determinants of consumers’ continuance intention (CI) toward online grocery shopping (OGS) across different country markets. Drawing on technology continuance theory (TCT), this study compared key drivers of CI in a different countries market.
Methods:
Data were collected via online surveys from 638 OGS users in China (n = 338) and South Korea (n = 300) between November and December 2023. A TCT-based model incorporating satisfaction, attitude, perceived usefulness (PU), perceived ease of use, confirmation, and CI was tested using partial least squares structural equation modeling. Partial measurement invariance testing was conducted to ensure valid cross-national comparison.
Results:
In South Korea, both satisfaction and attitude significantly predicted CI, with satisfaction exerting a particularly strong effect. In China, attitude was the primary determinant of CI, whereas satisfaction had minimal impact. Across both countries, PU consistently and positively influenced satisfaction and attitude, thereby indirectly enhancing CI. Partial measurement invariance was confirmed, validating comparisons of the model across contexts.
Conclusion
The findings suggest that the drivers of online grocery continuance differ by cross-national market. In Korean markets, strategies must enhance customer satisfaction (and its influence on attitude) to sustain OGS usage. In Chinese markets, fostering favorable consumer attitudes toward OGS is essential for promoting continued use. This cross-national analysis advances the theoretical understanding of continuance behavior while providing practical guidance for designing market-specific strategies to sustain online grocery engagement.

OBJECTIVE To investigate the mechanism of pachymic acid on renal injury in pregnancy induced hypertension (PIH) rats by regulating the silent information regulator transcript 1/peroxisome proliferator-activated receptor γ coactivator-1α (Sirt1/PGC-1α) pathway. METHODS Pregnant SD rats were prepared by co-caging and PIH model was induced using N-nitro-L- arginine methyl ester (L-NAME) method. PIH rats were randomly divided into model group, L-pachymic acid (low-dose pachymic acid, 10 mg/kg) group, H-pachymic acid (high-dose pachymic acid, 20 mg/kg) group, and H-pachymic acid+EX527 (20 mg/kg pachymic acid+10 mg/kg EX527) group, with 6 rats in each group. Another 6 normal pregnant rats were selected as blank group. Each group was given relevant medicine or solvent intragastrically or intraperitoneally daily, once a day, for 28 consecutive days. After the last administration, 24 h urinary protein and tail artery systolic blood pressure (SBP) were measured in pregnant rats from each group, along with the levels of serum creatinine (Scr), blood urea nitrogen (BUN),uric acid (UA), and cystatin C (Cys-C). The contents of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), and 8-hydroxy-2′-deoxyguanosine (8-OHdG) in renal tissue, as well as the mRNA and protein expression levels of Sirt1 and PGC-1α, were also determined. Meanwhile, renal histopathological changes in rats from each group were evaluated using hematoxylin-eosin (HE) staining and periodic acid-Schiff (PAS) staining. RESULTS Compared with model group, L-pachymic acid group and H-pachymic acid group exhibited significant decreases in 24 h urine protein quantification, tail artery SBP, Scr, BUN, UA, Cys-C levels, glomerulosclerosis index score of renal tissue, renal tubular injury score, the percentage of PAS positive area, MDA and 8-OHdG (P<0.05). Conversely, the contents of SOD and GSH-Px, along with the mRNA and protein expression levels of Sirt1 and PGC-1α, were significantly increased (P<0.05). Moreover, these improvements were more pronounced in H-pachymic acid group (P<0.05). Compared with H-pachymic acid group, the aforementioned indicators in pregnant rats from the H-pachymic acid+EX527 group showed significant reversal (P<0.05). CONCLUSIONS Pachymic acid significantly ameliorates renal injury induced by PIH in rats, potentially through activation of the Sirt1/PGC-1α pathway.

Lung cancer is the leading cause of cancer-related deaths worldwide, and tumor metastasis is a key factor contributing to the mortality of most lung cancer patients. Aberrant activation of epithelial-mesenchymal transition (EMT) is a major driver of lung cancer progression and metastasis. EMT is characterized by the loss of apical-basal polarity and intercellular adhesion in highly differentiated, polarized, and organized epithelial cells, which acquire motility, migratory potential, and invasive properties. During this process, cells undergo cytoskeletal remodeling and transform into a mesenchymal phenotype, accompanied by associated changes in cellular markers. The EMT process is highly complex and is tightly regulated by intricate networks involving multiple transcription factors, post-translational controls, epigenetic modifications, and non-coding RNAs. Therefore, therapies targeting the mechanisms of malignant transformation and their associated pathways in lung cancer are of significant clinical importance. In recent years, EMT has attracted increasing attention as a potential target for cancer therapy. Chinese medicine, with its characteristics of multi-target action, low side effects, and good therapeutic efficacy, has demonstrated an important role in anticancer treatment. A series of studies have investigated the role of Chinese medicine in inhibiting EMT in lung cancer. Active ingredients of Chinese medicine, including flavonoids, glycosides, phenols, terpenoids, saccharides, and alkaloids, as well as Chinese medicine compound formulas, have shown significant regulatory effects on EMT. Their mechanisms mainly involve multiple pathways, targets, and links, including signaling pathways, exosomes, microRNAs (miRNAs), and the tumor-associated immune microenvironment. This article summarizes the mechanisms by which EMT promotes malignant tumor progression and reviews the current research on how Chinese medicine active ingredients, monomers, and compound formulas inhibit EMT and suppress lung cancer cell migration and invasion. This study is expected to provide comprehensive theoretical information for basic and translational research on lung cancer.

Animal experimentation constitutes a critical link between basic research and clinical application, making its research quality and translational efficiency paramount. Although considerable progress has been made in standardizing operational procedures and ethical guidelines, the standardization of outcome evaluation systems has significantly lagged, creating a key bottleneck that constrains the quality of biomedical research and evidence synthesis. This deficiency is manifested by pronounced heterogeneity in outcome selection across similar studies, incomplete methodological reporting, and disparate criteria for result interpretation, which severely impairs the comparability of findings and the evidence integration. To cope with this challenge, this paper systematically introduces a mature methodological tool from clinical research–the core outcome set (COS)–and explores its construction strategies and application potential in the field of animal experimentation. Given the extensive diversity of animal experiments, a pragmatic strategy of "focusing on key areas, implementing phased pilots, and promoting gradual expansion" should be adopted. This approach prioritizes the development of domain-specific COS for disease areas characterized by high research volume, urgent translational needs, and well-established animal models. A multi-source integration pathway for COS development is detailed, comprising systematic literature searches, methodological appraisals, and expert consensus, with the feasibility of leveraging artificial intelligence (AI) to enhance efficiency also being examined. The development and promotion of such COS are not intended to restrict scientific exploration; rather, they aim to establish a new, tiered evaluation paradigm consisting of "core outcomes" (mandatory), "recommended outcomes" (encouraged), and "exploratory outcomes" (optional). This framework is expected not only to enhance research quality through standardization and to adhere to the "3R" principles but also to accelerate the accumulation of high-quality evidence. This, in turn, provides a solid foundation for higher-level evidence synthesis, ultimately facilitating the effective translation of basic research findings into clinical practice and providing an essential methodological framework for scientific advancement in relevant disciplines.

ObjectiveTo investigate the effect of Toxoplasma gondii infection on copper metabolism in the kidneys of mice. MethodsA total of 80 7-8-week-old C57BL/6 female mice were randomly divided into four groups of 20 mice in each group after one week of adaptation, including Control group, Cu group, TgCtwh6 group and Cu+TgCtwh6 group. Mice that were not infected and fed with normal diet and water were used as the Control group; Mice fed with 1 g/kg of copper chloride processing diet and 0.1% copper chloride water for 60 consecutive days were used as Cu group; Mice infected with 25-30 TgCtwh6 cysts (one of the predominant genotype Chinese 1 in China) fed with normal diet and water were used as the TgCtwh6 group; mice infected with 25-30 TgCtwh6 cysts and fed with a processed diet containing 1 g/kg of copper chloride and water with 0.1% copper chloride for 60 consecutive days were used as the Cu+TgCtwh6 group. ICP-MS was used to determine the changes in copper content in kidney tissues. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of mouse kidney tissue. The number of apoptotic cells was observed by PI staining. Western blot was used to detect the protein expression levels of glutathione peroxidase 4 (GPX4) and superoxide dismutase (SOD1, SOD2). RT-qPCR was used to detect the mRNA expression of cuproptosis-related genes. ResultsPathological manifestations such as inflammatory cell infiltration in the Cu group and TgCtwh6 group were seen under the microscope, and the inflammatory infiltrating cells of the renal interstitial were reduced in the Cu+TgCtwh6 group, and the pathological manifestations

OBJECTIVE To establish the graded management standards for off-label use of Shenqi fuzheng injection. METHODS Systematic searches were conducted in databases including CNKI, PubMed and the Cochrane Library to retrieve guidelines/consensuses, systematic reviews/meta-analyses, and randomized controlled trials (RCTs) of Shenqi fuzheng injection. The quality of evidence was evaluated using AGREE Ⅱ, AMSTAR Ⅱ, and the Risk of Bias 1.0 tool recommended by Cochrane Collaboration, and the graded management standard for off-label use of Shenqi fuzheng injection was developed by using the Thomson grading system. RESULTS A total of 534 articles were involved, including 11 guidelines, 22 systematic reviews/meta-analysis, and 501 RCTs. They covered 79 off-label indications for Shenqi fuzheng injection: cancer-related fatigue, colorectal cancer and breast cancer, all with high-quality evidence were classified under grade A management (grade Ⅰ commendation), allowing all physicians across the hospital to prescribe relevant treatments; five diseases, such as ovarian cancer, liver cancer, leukemia, heart failure and cerebral infarction, were classified under grade B management (grade Ⅱa commendation), with prescription restricted to physicians with intermediate or higher professional titles in specific departments; eleven diseases, including sepsis, cervical cancer, esophageal cancer, etc., were classified under grade C management (grade Ⅱb commendation), requiring strict evaluation by senior physicians before prescription; the use of Shenqi fuzheng injection for other conditions was explicitly prohibited due to a lack of sufficient evidence. CONCLUSIONS Off-label use of Shenqi fuzheng injection is prevalent. The graded management standard established by evidence-based medical approach provides a scientific basis for standardizing the clinical application of traditional Chinese medicine injections and offers an operable paradigm for implementing differentiated drug use supervision in medical institutions.

ObjectiveThis paper aims to study the potential active compound components and action mechanism of Shenqi Dihuangtang in the treatment of diabetic kidney disease (DKD) through network pharmacology and in vivo experimental verification. MethodsUltra-high-performance liquid chromatography-Q-exactive orbitrap mass spectrometry (UPLC-Q-Exactive Orbitrap MS) technology was used to clarify the main active chemical components of Shenqi Dihuangtang, and it was combined with network pharmacology methods such as gene ontology (GO) functional annotations and Kyoto encyclopedia of genes and genome (KEGG) to predict the potential action mechanism of Shenqi Dihuangtang in treating DKD. Subsequently, the DKD model of db/db male mice was established, and the mice were randomly divided into model group, low-dose Shenqi Dihuangtang group (6.10 g·kg-1), medium-dose Shenqi Dihuangtang group (12.19 g·kg-1), high-dose Shenqi Dihuangtang group (24.38 g·kg-1), and daplizin group (1.25 mg·kg-1). During the same period, C57BL/6J male mice were selected into normal group and received drug intervention for 8 weeks, respectively. During this period, the body weight and fasting blood glucose (FBG) of the mice were dynamically monitored, and oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were performed at the end of dosing. The levels of serum creatinine (SCr), blood urea nitrogen (BUN), uric acid (UA), albumin (ALB), and total protein (TP) were measured by an automatic biochemical analyzer, and 24-hour urine protein was measured by a urine protein quantitative kit. Hematoxylin-eosin (HE), periodic-acid Schiff (PAS), and Masson staining were employed to observe the renal histopathology. The expression of nephrotic protein Nephrin was observed by immunohistochemistry. Western blot was used to detect the expression of epithelial-mesenchymal transition (EMT)-related proteins such as TGF-β1, Smad2/3, α-smooth muscle actin (α-SMA), neural-cadherin (N-Cadherin), and snail protein. ResultsUPLC-Q-Exactive Orbitrap MS identified 384 active compounds in the aqueous extract of Shenqi Dihuangtang. According to oral bioavailability≥30% and the five drug-like principles, 44 key active ingredients were screened out, and 169 intersection targets highly correlated with DKD were matched. Among them, there was a significant interaction relationship between tumor necrosis factor(TNF), interleukin(IL)-6, protein kinase B(Akt)1, Caspase-3, Jun proto-oncogene (JUN), hypoxia inducible factor-1α(HIF-1α), B cell lymphoma-2(Bcl-2), matrix metallopeptidase-9(MMP-9), IL-1β, and TGF-β1. GO functional annotations were significantly enriched in cellular components such as membrane rafts, membrane microdomains, and collagen-containing extracellular matrix, molecular functions such as DNA-binding transcription factor binding, R-Smad binding, and Smad protein binding, as well as biological processes such as reactions to lipopolysaccharides(LPS), reactions to bacteria-derived molecules, and wound healing. The KEGG pathway was significantly enriched in lipids and atherosclerosis, TGF-β signaling pathway, phosphatidylinositol 3 kinase (PI3K)/Akt signaling pathway, etc. In vivo experimental results showed that the high-dose Shenqi Dihuangtang group could significantly reduce FBG levels in db/db mice (P<0.01), improve OGTT (P<0.01) and ITT (P<0.01) levels, reduce SCr (P<0.01), BUN (P<0.01), UA (P<0.01) and 24-hour BUN (P<0.01), and increase ALB (P<0.01) and TP (P<0.01) levels. Pathological staining confirmed that the high-dose Shenqi Dihuangtang group could significantly reduce the glomerular mesangial matrix area and collagen deposition (P<0.01) and upregulate the positive expression rate of Nephrin (P<0.01). Western blot results showed that the high-dose Shenqi Dihuangtang group significantly downregulated the expression of TGF-β1 (P<0.01) and Smad2/3 (P<0.01) signal molecules and inhibited the protein levels of α-SMA (P<0.01), N-Cadherin (P<0.01), and Snail (P<0.01). ConclusionShenqi Dihuangtang can inhibit the TGF-β1/Smad signaling axis and block the renal EMT process, thereby improving DKD renal fibrosis damage. Further analysis of its key active components and clinical transformation pathways is needed in the future.

ObjectiveTo investigate the effects of Tianma Goutengyin on the tumor necrosis factor-α (TNF-α)/signal transducer and activator of transcription 3 (STAT3)/α1-antichymotrypsin C-terminal tail fragment (α1ACT) signaling pathway and A1-type astrocytes in a rat model of vascular dementia. MethodsSeventy-two male Sprague-Dawley rats were randomly divided into six groups (n=12 per group): Sham-operated group, model group, Tianma Goutengyin high-, medium-, and low-dose groups (5.13, 10.26, and 20.52 g·kg-1), and a nimodipine group (8.1 mg·kg-1). The vascular dementia model was established by permanent bilateral common carotid artery occlusion, followed by 4 weeks of intervention. Learning and memory ability were evaluated using the novel object recognition test, and behavioral performance was assessed using the forced swimming test. Levels of interleukin-6 (IL-6) and C-C motif chemokine ligand 2 (CCL2) in hippocampal tissue were measured by enzyme-linked immunosorbent assay (ELISA). Hippocampal neuronal morphology was observed by Nissl staining, and apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL). Immunohistochemistry was used to detect positive expression of brain-derived neurotrophic factor (BDNF), glial fibrillary acidic protein (GFAP), and myelin basic protein (MBP). Western blot analysis was performed to measure the protein expression levels of TNF-α, TNF receptor 1 (TNFR1), phosphorylated STAT3 (p-STAT3), α1ACT, IL-6, complement component 3 (C3), BDNF, S100 calcium-binding protein A10 (S100A10), and GFAP in hippocampal tissue. ResultsCompared with the sham-operated group, the model group showed a significantly reduced relative recognition index in the novel object recognition test (P<0.01), prolonged immobility time and increased immobility frequency in the forced swimming test (P<0.01). Hippocampal IL-6 and CCL2 levels were significantly increased (P<0.01). Nissl staining revealed a marked reduction in neuronal number and loss of Nissl bodies (P<0.01). MBP-positive expression was significantly decreased (P<0.01), apoptosis was significantly increased (P<0.01), BDNF-positive expression was significantly reduced (P<0.05), and GFAP-positive expression was significantly increased (P<0.01). In addition, the protein expression levels of TNF-α, TNFR1, p-STAT3, α1ACT, IL-6, and C3 were significantly elevated (P<0.01), while BDNF and S100A10 expression levels were significantly decreased (P<0.01). Compared with the model group, all Tianma Gouteng yin dose groups exhibited a significant increase in the relative recognition index (P<0.05), shortened immobility time and reduced immobility frequency (P<0.05, P<0.01). IL-6 and CCL2 levels were significantly decreased (P<0.01), neuronal number was significantly increased (P<0.05, P<0.01), and MBP-positive expression was significantly enhanced (P<0.01). Apoptosis was significantly reduced (P<0.01), BDNF-positive expression was significantly increased (P<0.05), and GFAP-positive expression was significantly decreased (P<0.01). Moreover, the protein expression levels of TNF-α, TNFR1, p-STAT3, α1ACT, IL-6, and C3 were significantly decreased (P<0.01), while BDNF and S100A10 protein expression levels were significantly increased (P<0.01). ConclusionTianma Goutengyin may inhibit A1-type astrocyte activation in rats with vascular dementia through the TNF-α/STAT3/α1ACT signaling pathway, thereby reducing neuronal apoptosis and improving learning and memory function.
