OBJECTIVES: Exposure to rare earth elements (REEs) has been linked to various systemic diseases, but their impact on the offspring blood-brain barrier (BBB) via the gut-brain axis remains unclear. This study aims to investigate the effects of maternal exposure to neodymium oxide (Nd₂O₃) on the BBB integrity of offspring rats, and to evaluate the potential protective role of bifidobacterium tetrad viable tablets (BTVT) against Nd₂O₃-induced intestinal and BBB damage. METHODS: Healthy adult SD rats were mated at a 1:1 male-to-female ratio, with the day of vaginal plug detection marked as gestational day 0. A total of 60 pregnant rats were randomly assigned to the following groups: Control, 50 mg/(kg·d) Nd₂O₃, 100 mg/(kg·d) Nd₂O₃, 200 mg/(kg·d) Nd₂O₃, and 200 mg/(kg·d) Nd₂O₃ + BTVT group. Treatments were administered by daily oral gavage throughout pregnancy and lactation. On postnatal day 21 (weaning), offspring feces, brain, and colon tissues were collected. Hematoxylin and eosin (HE) staining was used to assess structural changes in brain and intestinal tissues. Short-chain fatty acids (SCFAs) in feces were quantified by gas chromatography-mass spectrometry (GC-MS). Evans Blue (EB) dye extravasation assessed BBB permeability. Gene and protein expression levels of tight junction proteins occludin and zonula occludens-1 (ZO-1) were measured by reverse transcription PCR (RT-PCR) and Western blotting (WB), respectively. Neodymium levels in brain tissue were determined via inductively coupled plasma mass spectrometry (ICP-MS). RESULTS: HE staining revealed that maternal Nd₂O₃ exposure caused mucosal edema, increased submucosal spacing, and lymphocyte infiltration in offspring colon, as well as neuronal degeneration and vacuolization in brain tissue. BTVT intervention alleviated these changes. GC-MS analysis showed that levels of acetic acid, propionic acid, butyric acid, and isobutyric acid significantly decreased, while valeric acid and isovaleric acid increased in offspring of Nd₂O₃-exposed mothers (P<0.05). BTVT significantly restored levels of acetic, propionic, and isobutyric acids and reduced valeric acid content (P<0.05). EB permeability was significantly elevated in Nd₂O₃-exposed offspring brains (P<0.05), but reduced with BTVT treatment (P<0.05). RT-PCR and WB showed downregulation of occludin and ZO-1 expression following Nd₂O₃ exposure (P<0.05), which was reversed by BTVT (P<0.05). ICP-MS results indicated significantly increased brain neodymium levels in offspring from all Nd₂O₃-exposed groups (P<0.05), while BTVT significantly reduced neodymium accumulation compared to the 200 mg/(kg·d) Nd₂O₃ group (P<0.05). CONCLUSIONS Maternal exposure to Nd₂O₃ during pregnancy and lactation disrupts intestinal health and BBB integrity in offspring, elevates brain neodymium accumulation, and induces neuronal degeneration. BTVT effectively mitigates Nd₂O₃-induced intestinal and BBB damage in offspring, potentially through modulation of the gut-brain axis.

In general, bioassay-guided fractionation and isolation of bioactive constituents from botanical materials frequently ended up with the reward of a single compound. However, botanical materials typically exert their therapeutic actions through multi-pathway effects due to the intrinsic complex nature of chemical constituents. In addition, the content of bioactive compounds in botanical materials is largely dependent on humidity, temperature, soil, especially geographical origins, from which rapid and accurate identification of plant materials is pressingly needed. These long-standing obstacles collectively impede the deep exploitation and application of these versatile natural sources. To address the challenges, a new paradigm integrating biogravimetric analyses and machine learning-driven origin classification (BAMLOC) was developed. The biogravimetric analyses are based on absolute qHNMR quantification and in vivo zebrafish model-assisted activity index calculation, by which bioactive substance groups jointly responsible for the bioactivities in all fractions are pinpointed before any isolation effort. To differentiate origin-different botanical materials varying in the content of bioactive substance groups, principal component analysis, linear discriminant analysis, and hierarchical cluster analysis in conjunction with supervised support vector machine are employed to classify and predict production areas based on the detection of volatile organic compounds by E-nose and GC-MS. Expanding BAMLOC to Codonopsis Radix enables the identification of polyacetylenes and pyrrolidine alkaloids as the bioactive substance group for immune restoration effect and accurately determines the origins of plants. This study advances the toolbox for the discovery of bioactive compounds from complex mixtures and lays a more definitive foundation for the in-depth utilization of botanical materials.

Objective Two-sample Mendelian randomization(MR)analysis was used to explore the causal relationship between hyperthyroidism/hypothyroidism and insomnia.Methods A two-sample MR method was adopted.The exposure factors were hyperthyroidism/hypothyroidism,and the outcome was insomnia.The instrumental variables were screened.Inverse variance weighting(IVW)was mainly used to analyze the causal relationship between hyperthyroidism/hypothyroidism and insomnia.Meanwhile,MR-Egger,weighted mode,weighted median,and simple mode were used to supplement the IVW analysis results.Cochran's Q test was used to determine the statistical heterogeneity among single nucleotide polymorphism(SNP),and the intercept term of MR-Egger was used to evaluate whether SNP had horizontal pleomorphism.The influence of a single SNP on the IVW analysis results was evaluated by the retention of one method.To avoid reverse causality,insomnia was taken as the exposure factor and hyperthyroidism/hypothyroidism as the outcome event for reverse MR analysis.Results A total of 11 SNP strongly related to hyperthyroidism were screened out.After eliminating the palindromic sequences,9 SNP strongly related to hyperthyroidism were finally included.The IVW analysis results showed that hyperthyroidism increased the risk of insomnia(OR=1.01,95％CI:1.00-1.01,P=0.012).A total of 68 SNP strongly related to hypothyroidism were screened out.After removing the palindromic sequences,61 SNP highly related to hypothyroidism were finally included.The IVW analysis results showed that hypothyroidism increased the risk of insomnia(OR=1.01,95％CI:1.00-1.01,P=0.021).The results of Cochran's Q test showed that there was no heterogeneity in the instrumental variable hyperthyroidism(P=0.60).The MR-Egger intercept analysis indicated that studies with hyperthyroidism/hypothyroidism as exposure and insomnia as the outcome did not have horizontal pleiotropy(P＞0.05).Reverse MR analysis revealed that exposure factors such as insomnia had no causal relationship with hyperthyroidism(OR=1.57,95％CI:0.55-4.50,P=0.40)or hypothyroidism(OR=1.09,95％CI:0.74-1.61,P=0.66).Conclusion Hyperthyroidism/hypothyroidism can increase the risk of insomnia.

Objective:To investigate the molecular mechanisms of chronic rhinosinusitis (CRS), to identify key cell subgroups and genes, to construct effective diagnostic models, and to screen for potential therapeutic drugs.Methods:Key cell subgroups in CRS were identified through single-cell transcriptomic sequencing data. Essential genes associated with CRS were selected and diagnostic models were constructed by hdWGCNA (high dimensional weighted gene co-expression network analysis) and various machine learning algorithms. Causal inference analysis was performed using Mendelian randomization and colocalization analysis. Potential therapeutic drugs were identified using molecular docking technology, and the results of bioinformatics analysis were validated by immunofluorescence staining. Graphpad Prism, R, Python, and Adobe Illustrator software were used for data and image processing.Results:An increased proportion of basal and suprabasal cells was observed in CRS, especially in eosinophilic CRS with nasal polyps (ECRSwNP), with P=0.001. hdWGCNA revealed that the "yellow module" was closely related to basal and suprabasal cells in CRS. Univariate logistic regression and LASSO algorithm selected 13 key genes ( CTSC, LAMB3, CYP2S1, TRPV4, ARHGAP21, PTHLH, CDH26, MRPS6, TENM4, FAM110C, NCKAP5, SAMD3, and PTCHD4). Based on these 13 genes, an effective CRS diagnostic model was developed using various machine learning algorithms (AUC=0.958). Mendelian randomization analysis indicated a causal relationship between CTSC and CRS (inverse variance weighted: OR=1.06, P=0.006), and colocalization analysis confirmed shared genetic variants between CTSC and CRS (PPH4/PPH3>2). Molecular docking results showed that acetaminophen binded well with CTSC (binding energy:-5.638 kcal/mol). Immunofluorescence staining experiments indicated an increase in CTSC +cells in CRS. Conclusion:This study integrates various bioinformatics methods to identify key cell types and genes in CRS, constructs an effective diagnostic model, underscores the critical role of the CTSC gene in CRS pathogenesis, and provides new targets for the treatment of CRS.

【Objective】 To explore the relationship of victimization, bullying tolerance and anxiety/depression in adolescents, and to examine the moderating effect of cognitive emotion regulation strategies on the relationship between bullying tolerance and anxiety/depression, in order to provide basis for intervention. 【Methods】 From January 2019 to July 2020, 1 768 adolescents were selected into this survey, and completed Bully/Victim Questionnaire, Primary and Secondary School Bullying Tolerance Questionnaire, Cognitive Emotion Regulation Questionnaire and the 28 General Health questionnaires. 【Results】 Adolescents′ victimization was relatively common and serious, the proportion of verbal bullying, relational bullying, and physical bullying was 57.64% (1 019/1 768), 36.60% (647/1 768), and 22.40% (396/1 768), respectirely. The scores of anxiety and depression of adolescents with different gender (t=2.00), school stage (F=101.38) and academic performance (F=27.91) were statistically significant (P<0.05).Victimization and bullying tolerance had predictive effect on adolescents′ anxiety/depression (β=0.14, 0.13, P<0.01).Positive strategies, negative strategies had significant moderating effects on the relationship between bullying tolerance and anxiety/depression(β=-0.10、0.08, P<0.01).The simple slope analysis showed that at high positive strategy level, bullying tolerance had no significant predictive effect on anxiety/depression (P>0.05), while at a low positive strategy level, bullying tolerance had significant predictive effect on anxiety/depression (β=0.28, P<0.01).At a high negative strategy level, bullying tolerance had a significant predictive effect on anxiety/depression (β=0.25, P<0.01), while at a low negative strategy level, bullying tolerance had no significant predictive effect on anxiety/depression (P>0.05). 【Conclusions】 Victimization and bullying tolerance positively predict adolescent anxiety/depression.High levels of positive and low levels of negative strategies effectively inhibit the risk of anxiety/depression, while low levels of positive and high levels of negative strategies amplify the risk of anxiety/depression.

A retrospective study was conducted on data of 23 patients with pancreatic duct diseases who were underwent peroral pancreatoscopy (POPS) at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from August 2020 to October 2022. The intraoperative observation, postoperative complications, and the diagnosis and treatment of POPS for pancreatic duct diseases were analyzed. All patients underwent POPS and achieved technical success. Among them, 7 patients were diagnosed as having intraductal papillary mucinous neoplasm of pancreas and 3 pancreatic malignant tumor. Eight patients with pancreatolithiasis accepted laser or eletrohydraulic lithotripsy under POPS. Abdominal pain improved in 2 patients with chronic pancreatitis after treatment. Melena disappeared in 2 patients with pancreatic duct hemorrhage or pancreatic enterostomy inflammation after conservative treatment. The symptom of 1 patient with pancreatic enterostomy stenosis improved after balloon dilation. There was no complication in the 23 patients, and the operation time was 35-90 min. The results indicate POPS is safe, effective with distinctive advantages in the diagnosis and treatment for pancreatic duct diseases.
