ObjectiveThis paper aims to investigate the role of NDC80 kinetochore complex component (NUF2) and magnesium homeostasis in ovarian cancer cell apoptosis, as well as the regulatory mechanism of gypenoside L (Gyp-L) on NUF2 and magnesium homeostasis. MethodsOvarian cancer OVCAR3 cells were divided into a blank control group, a low-concentration Gyp-L group (50 µmol·L-1), a high-concentration Gyp-L group (100 µmol·L-1), and a cisplatin (15 µmol·L-1) group. The migration, proliferation, and apoptosis capabilities of OVCAR3 cells were evaluated through cell scratch assays, clonal experiments, and terminal-deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay (TUNEL) staining. Differentially expressed genes of ovarian cancer were screened by using the Gene Expression Omnibus (GEO) database. The interaction relationships of differentially expressed genes and proteins were analyzed via the Search Tool for Recurring Instances of Neighbouring Genes (STRING) database. The prognostic survival analysis was performed by using the Tumor Immune Estimation Resource (TIMER) database, and the differential expression levels of genes were validated with the Gene Expression Profiling Interactive Analysis (GEPIA) database. The mRNA expression levels of NUF2, magnesium homeostasis-related indicators, such as magnesium transporter 1 (MAGT1), non-imprinted in Prader-Willi/Angelman syndrome 1 (NIPA1), NIPA-like domain containing 1 (NIPAL1), as well as apoptosis-related indicators B cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax) in OVCAR3 cells, were detected by real-time quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of NUF2, MAGT1, NIPA1, NIPAL1, Bcl-2, and Bax in OVCAR3 cells were quantitatively analyzed by ProteinSimple WES. A model of overexpression of NUF2 was constructed, and Gyp-L intervention was performed. The molecular mechanism by which Gyp-L induces ovarian cancer cell apoptosis by regulating NUF2 and influencing magnesium homeostasis was quantitatively analyzed and detected through cell cloning, TUNEL staining, Real-time PCR, and ProteinSimple WES. Finally, the Mg2+ content and protein synthesis efficiency were detected by immunofluorescence. ResultsGyp-L significantly inhibited the migration and proliferation capabilities of OVCAR3 cells and promoted their apoptosis (P<0.05). Overexpression of NUF2 markedly increased the expression levels of MAGT1, NIPA1, NIPAL1, and Bcl-2, while reducing the expression level of Bax (P<0.05). It also significantly elevated intracellular Mg2+ content and protein synthesis efficiency and simultaneously inhibited apoptosis (P<0.05). Gyp-L could reverse the magnesium homeostasis imbalance and apoptosis inhibition caused by the overexpression of NUF2, downregulating the expression levels of NUF2, MAGT1, NIPA1, NIPAL1, and Bcl-2 (P<0.05), while upregulating the expression level of Bax (P<0.05). ConclusionGyp-L can inhibit the occurrence of ovarian cancer, and its mechanism may involve inhibiting the expression of NUF2 to maintain magnesium homeostasis and inducing apoptosis of ovarian cancer cells.

Objective To investigate the temporal changes in pathological damage and macrophage polarization in liver and spleen tissues of mice infected with Angiostrongylus cantonensis, and to preliminarily unravel the peripheral immune responses during the early stage of A. cantonensis infection. Methods Forty female BALB/c mice at ages of 6 to 8 weeks were randomly divided into four groups, including the control group and 7-, 14-, and 21-day infection groups, with 10 mice in each group. Each mouse in the infection groups was inoculated with 30 third-stage (L3) larvae of A. cantonensis by oral gavage, and five mice were randomly selected from each infection group on days 7, 14, and 21 post-infection, while mice in the control group were given the same volume of physiological saline and five mice were randomly selected from the control group on the day of oral gavage. Mouse liver and spleen tissues were sampled. The histopathological changes of mouse liver and spleen tissues were observed using hematoxylin and eosin (HE) staining, and the percentage of positive staining area and the co-localization positive rates of the macrophage surface antigens F4/80, CD86, and CD206 were quantified in mouse liver and spleen tissues using immunohistochemical and immunofluorescence staining. In addition, five mice were collected from each infection group on days 7, 14, and 21 post-infection, and five mice were collected from the control group on the day of oral gavage. Mouse liver and spleen tissues were sampled for detection of macrophage markers CD86 and CD206 and macrophage phenotyping using flow cytometry, and the expression of M1 macrophage markers, including inducible nitric oxide synthase (Nos2), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and M2 markers, including arginase 1 (Arg1), mannose receptor C-type 1 (Mrc1) and chitinase-like protein 3 (Chil3) was quantified in mouse liver and spleen tissues using real-time quantitative PCR (RT-qPCR) assay. Results Proliferative lesions of the hepatocyte were observed in mouse liver tissues and the follicular structures of the mouse spleen white pulp were disrupted 21 days post-infection with A. cantonensis. Immunohistochemical staining showed that there were significant differences in the percentages of F4/80, CD86 and CD206 positive staining areas in the liver and spleen tissues among the four groups of mice (F = 242.40, 197.14, 183.19, 157.65, 242.35 and 146.24; all P values < 0.001), and the percentages of positive staining in the liver and spleen tissues of mice in the 14-day infection group [(4.45 ± 0.51)%, (3.74 ± 0.67)%, (8.32 ± 0.72)%, (16.56 ± 1.14)%, (11.62 ± 0.52)%, and (8.29 ± 0.72)%, respectively] and the 21-day infection group [(3.70 ± 0.11)%, (3.22 ± 0.43)%, (11.53 ± 1.03)%, (12.59 ± 1.05)%, (9.02 ± 0.83)%, and (11.67 ± 1.10)%, respectively] were higher than in the control group [(0.35 ± 0.16)%, (0.40 ± 0.02)%, (0.93 ± 0.05)%, (2.78 ± 0.26)%, (2.33 ± 0.20)%, and (1.85 ± 0.20)%, respectively] (all P values < 0.05). Immunofluorescence staining showed significant differences in the positive rates of F4/80 co-localization with CD86 and CD206 in mouse liver and spleen tissues among the four groups (F = 24.42, 25.28, 54.51 and 130.55; all P values < 0.001). Flow cytometry detected significant differences in the proportions of CD86+ and CD206+ macrophages in mouse liver and spleen tissues among the four groups (F = 67.98, 18.41, 29.77, 172.80; all P values < 0.001), and the proportions of CD206+ macrophages in the liver and spleen of the 21-day infection group were significantly higher than those in the control group [(9.25 ± 2.55)% vs (3.83 ± 0.72)%, and (4.22 ± 0.56)% vs (0.47 ± 0.18)%, respectively] (both P values < 0.05). In addition, RT-qPCR assay quantified significant differences in the relative mRNA expression of M1 macrophage markers (IL-1β, TNF-α and Nos2) and M2 macrophage markers (Arg1, Chil3 and Mrc1) in mouse liver and spleen tissues among the four groups (F = 41.30, 31.82, 199.33, 19.96, 62.01, 119.76, 23.67, 95.90, 72.27, 82.59, 123.41 and 29.75; all P values < 0.05). Conclusions A. cantonensis infection may cause progressive pathological damage in mouse liver and spleen tissues, accompanied by dynamic temporal changes in macrophage polarization. M1 macrophage polarization predominates at the early stage of A. cantonensis infection and shifts towards M2 polarization at the later stages, suggesting that M2 polarization may participate in immune regulation at late stages of A. cantonensis infection by suppressing excessive inflammatory responses and promoting tissue repair.

Objective:
To elucidate the biological basis of traditional Chinese medicine (TCM) syndromes from the perspective of “same syndrome, different diseases” in patients with chronic hepatitis B (CHB), liver cirrhosis (LC), and hepatocellular carcinoma (HCC), thereby providing a complementary approach for the diagnosis and treatment of chronic liver diseases (CLD).
Methods:
To investigate the dynamic characteristics of TCM syndromes in CLD, transcriptomic profiling of peripheral blood mononuclear cells (PBMCs) was performed from patients with CHB, LC, or HCC presenting with three TCM syndromes: liver gallbladder dampness heat syndrome (LGDHS), liver depression spleen deficiency syndrome (LDSDS), and liver kidney Yin deficiency syndrome (LKYDS). These participants were recruited at Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine between August 1, 2018 and December 31, 2021. Differentially expressed genes (DEGs) were identified using the random variance model (RVM) F test with false discovery rate (FDR) correction. Principal component analysis (PCA) and unsupervised hierarchical clustering were applied to visualize sample grouping. Dynamic network biomarkers (DNB) analysis was employed to detect critical transition stages during syndrome evolution, followed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses to characterize the functional roles and pathway involvement of the DNB members. Random forest (RF) analysis and the area under the receiver operating characteristic (ROC) curves (AUC) were used to rank the importance of candidate genes. External validation was performed using microarray data from an independent CLD cohort (GSE89377) and RNA-seq data from The Cancer Genome Atlas Liver Hepatocellular Carcinoma (TCGA-LIHC) dataset. Additionally, reverse transcription quantitative polymerase chain reaction (RT-qPCR) was performed on an independent cohort of LC patients to validate the expression levels of the candidate genes.
Results:
The study included a total of 132 participants. DNB analysis identified LDSDS stage as a critical tipping point during TCM syndrome evolution across CHB, LC, and HCC. The phosphoinositide 3-kinase/protein kinase B (PI3K-AKT) signaling pathway was consistently enriched in the DNB analysis across all three types of CLD, suggesting its potential involvement in the critical transition of TCM syndromes. Among the 24 core DNB members of the PI3K-AKT pathway, four genes—integrin subunit beta 1 (ITGB1), collagen type IV alpha 1 chain (COL4A1), collagen type IV alpha 2 chain (COL4A2), and DNA damage inducible transcript 3 (DDIT3)—were identified by RF analysis (Gini score > 1) and ROC analysis. ROC analysis demonstrated high discriminative ability for distinguishing LGDHS from LKYDS in CHB patients, with AUC of

Endocrinology and Metabolism 2026;41(2):256-266
Background:
While observational studies have suggested a potential link between metabolic syndrome (MetS) and an increased risk of colon polyps, the causal nature of this association remains uncertain. This study used a two-sample Mendelian randomization (MR) approach to evaluate the relationship between MetS and colon polyps.
Methods:
A two-sample MR analysis was performed using data on MetS, its indicators, and colon polyps obtained from publicly available genome-wide association studies in the Integrative Epidemiology Unit (IEU) and MAGIC databases. Outliers were removed using Mendelian Randomization Pleiotropy RESidual Sum and Outlier (MR-PRESSO), followed by MR calculations and false discovery rate (FDR) correction. The primary analysis was conducted with the inverse variance-weighted (IVW) method.
Results:
The IVW results indicated no association between hypertension, hyperlipidemia, or diabetes and the risk of colon polyps. High-density lipoprotein cholesterol (HDL-C) (P=0.005), 2-hour glucose (P=0.004), glycated hemoglobin A1c (P=0.004), and the ratio of omega-6 to omega-3 fatty acids (P<0.001) were negatively associated with colon polyps. Conversely, body mass index (BMI) (P<0.001), body fat percentage (P=0.002), waist-to-hip ratio adjusted for BMI (P=0.001), total cholesterol (TC) (P=0.002), triglycerides (TG) (P<0.001), and both omega-3 (P<0.001) and omega-6 fatty acid levels (P=0.02) were positively associated with colon polyps. The relationships between these metabolic indicators and colon polyps remained significant after FDR correction.
Conclusion
Obesity-related traits, TC, and TG may increase the risk of colon polyps, while HDL-C may have a protective effect.

Prolonged standing work can lead to various lower limb health issues. Footwear, as a convenient and noninvasive intervention, plays a key role in foot protection. The purpose of this review was to evaluate the impact of footwear characteristics on foot comfort among workers engaged in prolonged standing occupations. A systematic search of PubMed, Web of Science, Scopus, and the Cochrane Library was conducted until March 2025 for experimental and observational studies; the review is registered in International Prospective Register of Systematic Reviews (CRD420251003253).Given the diversity of study designs, participant characteristics, and outcome measures, results were synthesized narratively, organizing findings by footwear design factors. The synthesis indicated that soft soles reduce foot impact and fatigue but offer limited support, whereas hard soles enhance stability but may cause localized pressure and discomfort. Sole hardness should balance cushioning and support based on activity: hard soles for standing and soft soles for walking. Insole hardness must be carefully considered as semirigid arch supports can cause discomfort. Most insoles improve pressure distribution by adjusting arch loading, and some enhance intrinsic foot muscles by promoting toe engagement, reducing leg swelling. Custom orthotic insoles outperform standard ones in comfort and balance. Future research should promote interdisciplinary collaboration with footwear designers to explore key design parameters and establish a scientific framework for protective footwear.

This study explores methodological issues in the design, evaluation, and reporting of randomized controlled trials (RCTs) under the concept of "syndrome dominating disease". The discussion focuses on key aspects including the adaptability of trial design, the screening of research participants, the standardization of syndrome differentiation, the balance between intervention individualization and standardization, the integration of multi-dimensional outcome measures, and the limitations of existing evaluation and reporting tools when applied to this type of research, along with corresponding recommendations and future perspectives. Regarding research design, it is recommended to select or draw upon innovative design concepts such as basket trials and subgroup-based dynamic/static parallel-group designs, in order to innovate the design format of RCTs. Meanwhile, criteria for participant screening, TCM syndrome differentiation, and disease classification should be standardized. The balance should be appropriately achieved between intervention individualization and standardization, and a multidimensional assessment system encompassing TCM syndromes, disease-specific outcomes, and patient-reported outcomes should be established. For risk of bias assessment and research reporting, it is recommended,to develop specialized assessment and reporting tools based on existing instruments, in order to standardize the assessment and reporting of study findings. Future research may further explore the potential applications of artificial intelligence in the study design, risk-of-bias assessment, and reporting quality assessment of RCTs based on the "syndrome dominating disease" model, with a particular focus on methodological optimization, data integration, and enhancement of research quality.

ObjectiveTo explore the molecular mechanism through which modified Guizhi Fulingwan (MGZFLW) promotes apoptosis and inhibits prostate cancer through the miR-34a-5p/δ-like protein 1 (DLL1)/Notch signaling pathway based on the traditional Chinese medicine theory of Yang transforming Qi while Yin constituting form. MethodsThe optimal intervention conditions of MGZFLW-containing serum and docetaxel (DXT) were screened by the cell counting kit-8 (CCK-8) method. Human prostate cancer cells (PC-3) were allocated into blank, MGZFLW (10%), and DXT (30 nmol·L-1) groups. The effects of MGZFLW-containing serum on the migration and proliferation of PC-3 cells were evaluated by cell scratch and colony formation assays, and the apoptosis of PC-3 cells was detected by terminal-deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay. The cells were transfected with miR-34a-5p mimics and miR-34a-5p inhibitor. The mRNA levels of miR-34a-5p, DLL1, Notch1 and its downstream effector factors Notch1 intracellular domain (NICD1), Hes family basic helix-loop-helix transcription factor 1 (Hes1), and hairy/enhancer-of-split related with YRPW motif 1 (Hey1) were determined by Real-time PCR. The protein levels of DLL1, Notch1, NICD1, Hes1, and Hey1 were determined by a WES fully automatic protein system. The effect of miR-34a-5p on the DLL1-mediated Notch pathway was evaluated based on the results. Further, after MGZFLW-containing serum intervention, the expression of DLL1 and Notch1 was detected by the immunofluorescence (IF) assay, and the mRNA and protein levels of miR-34a-5p/DLL1/Notch pathway-related molecules were quantified by Real-time PCR and the WES fully automatic protein system, respectively, to explore the regulatory effect of MGZFLW-containing serum on the miR-34a-5p/DLL1/Notch pathway. ResultsMGZFLW-containing serum inhibited the viability, migration, and proliferation and promote the apoptosis of PC-3 cells (P<0.01). The overexpression of miR-34a-5p down-regulated the mRNA and protein levels of key molecules in the DLL1/Notch signaling pathway and promoted cell apoptosis (P<0.01), while inhibition of miR-34a-5p had the opposite effects. MGZFLW-containing serum reversed the activation of the DLL1/Notch pathway and the inhibition of apoptosis caused by miR-34a-5p inhibition, up-regulated the expression of miR-34a-5p, and down-regulated the expression of related molecules in this pathway (P<0.01). ConclusionMGZFLW can up-regulate the expression of miR-34a-5p to inhibit the DLL1/Notch signaling pathway and promote the apoptosis of prostate cancer cells, thereby inhibiting prostate cancer. This study provides experimental evidence for clarifying the molecular mechanism of the anti-prostate cancer effect of this formula.

Objective:
To investigate the environmental contamination of norovirus in nurseries and primary/secondary schools, so as to provide a scientific basis for effective prevention and control measures.
Methods:
A total of 483 external environmental samples were collected from 34 cluster outbreaks of norovirus gastroenteritis in kindergartens and primary/secondary schools in Linhai City from 2021 to 2024. Pathogen detection was conducted using a rapid nucleic acid extraction kit and realtime fluorescence RT-PCR, and the results were analyzed using the χ2 test or Fishers exact test.
Results:
Among the collected external environmental samples, the total positive rate of surface contamination was 13.66%. The positive rates in kindergartens and primary/secondary schools were 12.20% and 15.82%, respectively. In kindergartens, the five surfaces with the highest detection rates were desks/chairs (23.33%), toilet stool troughs (20.69%), urinal troughs (12.00%), washbasins/sinks (11.11%), and toilet mops (9.38%). In primary/secondary schools, the top five were toilet stool troughs (38.30%), urinal troughs (23.53%), toilet door handles (13.04%), toilet mops (12.50%), and drinking cups (11.11%). The difference in positive detection rates among different external environments in primary/secondary schools was statistically significant (Fishers exact probability test, P<0.01). The positive detection rate in sanitary toilets was higher than that in classroom environments (χ2=17.38), while the positive detection rate in classroom environments of kindergartens was higher than that in primary/secondary schools (χ2=5.42)(P<0.05).
Conclusions
Norovirus exhibits a high contamination rate in nurseries and schools, particularly in restroom areas. Strengthening sanitation and disinfection in highrisk environments, and improving hygiene awareness among children and staff, are essential for the effective prevent and control of norovirus.
