BackgroundAdverse childhood experiences (ACEs) are strong predictors of psychopathology across the lifespan, exerting extensive adverse effects on physical and mental health during early development. While ACEs increase the risk of childhood psychopathology, sleep quality and impair cognitive function, the early neurobiological mechanisms mediating ACE-induced cognitive impairment remain unclear. ObjectiveTo explore the association between ACEs exposure and the risk of psychopathology, sleep disorders, and cognitive function, and to examine the mediating role of the putamen volume in the relationship between ACEs and cognitive function from a neurodevelopment perspective. MethodsData were obtained from the Adolescent Brain Cognitive Development (ABCD) study, comprising 10 572 children aged 9 to 10. Participants were categorized into five groups based on the cumulative score of ACEs reported by their parents and the children themselves: no-exposure group (0 types of ACEs), the one-exposure group, the two-exposure group, the three-exposure group, and the high-risk exposure group (≥ 4 types of ACEs). Logistic regression analysis was employed to evaluate the association between ACEs and psychopathological symptoms [T score of the Child Behavior Checklist (CBCL) ≥ 65]. Multiple linear regression analysis was ultilized to analyze the correlations between ACEs and the scores of the Sleep Disturbance Scale for Children (SDSC), the NIH Toolbox Cognition Battery (NIHTB-CB), as well as the multiple structures in the cerebral cortex and subcortex. The Bootstrap method was applied to test the mediating effect of the putamen volume between ACEs and neurocognitive function. ResultsAfter adjusting for confounders, ACEs cumulative score was correlated with children's psychopathological symptoms in a dose-response manner. Compared with the no-exposed group, the high-risk exposure group had a 2.08-fold (OR=2.080, 95% CI: 1.401–3.088) increased risk of internalizing problems and a 3.13-fold (OR=3.132, 95% CI: 1.703–5.760) increased risk of externalizing problems, and the risk of conduct problems was 4.68 times that of the no-exposed group (OR=4.681, 95% CI: 2.528–8.669). ACEs cumulative score positively predicted the total score of SDSC (β=0.080, 95% CI: 0.059–0.102), with relatively stronger predictive effects on sleep-wake transition disorder (β=0.086, 95% CI: 0.063–0.109) and sleep onset and maintenance disorder (β=0.066, 95% CI: 0.043–0.089). In terms of neurocognition and brain structure, ACEs cumulative score negatively predicted the overall cognitive composite score (β=-0.025, 95% CI: -0.050–-0.001), the crystallized cognitive composite score (β=-0.035, 95% CI: -0.060–-0.010), the volume of the left putamen nucleus (β=-0.025, 95% CI: -0.046– 0.003), and the volume of the right putamen nucleus (β=-0.023, 95% CI: -0.044– 0.003). The total putamen volume played a partial mediating role between ACEs and the overall cognitive composite score, the effect value was -0.002 (95% CI: -0.004–-0.001), accounting for 7.49% of the total effect. ConclusionACEs exposure may increase the risk of psychopathological and sleep disturbances in children and may impair neurocognitive function. Reduced putamen volume may serve a potential neurobiological pathway underlying the impact of ACEs on childhood cognition.

ObjectiveTo investigate the mechanism of the modified of Bazhentang combined with Guishentang in improving pregnancy outcomes in mouse models of embryo implantation dysfunction by regulating T helper 1/T helper 2 (Th1/Th2) immune balance. MethodsEighty ICR female mice were randomly divided into four groups (n=20 per group) on gestational day 1 (GD1): control, model, western medicine, and traditional Chinese medicine (TCM) groups. Except for the control group, all mice received mifepristone solution (0.2 mg/mouse) via oral gavage on GD4 to induce embryo implantation dysfunction. The TCM group received a water decoction of the modified of Bazhentang combined with Guishentang (20.8 g·kg-1), with the western medicine group administered dydrogesterone (3.9 mg·kg-1), and the control/model groups given equal volumes of saline. All treatments were administered once daily from GD1 until one day before sample collection. Outcomes included implantation site counts (macroscopic observation), pregnancy rates, body weight, endometrial histopathology (hematoxylin-eosin staining), uterine expression of T-box expressed in T cells (T-bet), GATA-binding protein 3 (GATA3), interferon gamma (IFN-γ), and interleukin-4 (IL-4) at protein (Western blot) and mRNA (real-time polymerase chain reaction, Real-time PCR) levels, serum IFN-γ and IL-4 levels (enzyme-linked immunosorbent assay, ELISA), and Th1/Th2 immune balance evaluated by calculating T-bet/GATA3 and IFN-γ/IL-4 ratios. ResultsCompared to the control group, the model group showed no significant change in pregnancy rate but exhibited a marked reduction in average implantation sites and body weight (P<0.01). Histopathological analysis revealed endometrial abnormalities, including decreased glandular density, stromal compaction, and absence of nucleolar vacuoles. At the molecular level, uterine tissue in the model group demonstrated significantly upregulated expression of T-bet and IFN-γ (P<0.05, P<0.01), alongside markedly downregulated GATA3 and IL-4 expression (P<0.05, P<0.01). Serum analysis confirmed markedly elevated IFN-γ (P<0.01) and reduced IL-4 levels (P<0.01), resulting in significantly increased T-bet/GATA3 and IFN-γ/IL-4 ratios (P<0.01). Compared to the model group, pregnancy rates in all treatment groups showed no significant change. Implantation sites and body weight increased substantially (P<0.01), with restored endometrial morphology characterized by enhanced glandular density, stromal edema, and reappearance of nucleolar vacuoles. Significant downregulation of T-bet and IFN-γ (P<0.01) and upregulation of GATA3 and IL-4 (P<0.05, P<0.01) in uterine tissue were observed. Serum IFN-γ levels were significantly reduced (P<0.05, P<0.01), while IL-4 levels were significantly elevated (P<0.05). The Th1/Th2 ratios were significantly decreased (P<0.01). ConclusionThe modified of Bazhentang combined with Guishentang significantly enhances the number of embryo implantation sites in mice with embryo implantation dysfunction, potentially through modulating T-bet/GATA3 expression, restoring Th1/Th2 immune balance, and improving endometrial receptivity.

Objective The aim of this study was to characterize the basic molecular and biochemical parameters for a cyclophilin protein in Cryptosporidium parvum called CpCyP1.Methods CpCyP1 expression patterns during the parasite life cycle were evaluated using qRT-PCR with total RNA isolated from different developmental stages of C.parvum.Native CpCyP1 protein in sporozoites was detected using western blot.The localization of CpCyP1 was performed using the immunofluorescence assay,with an affinity-purified rabbit polyclonal antibody against a synthetic peptide.The peptidyl-prolyl cis-trans isomerase(PPIase)activity of His-tagged recombinant CpCyP1 was evaluated using absorbance colorimetry,and the effect of cyclosporin A(CsA)on the activity of CpCyP1 was determined.Results CpCyP1 was expressed in all parasite developmental stages,whereas CpCyP1 was present mainly in the cytosol of sporozoites,meronts,and gamonts.CpCyP1 displayed Michaelis-Menten kinetics towards N-succinyl-Ala-Ala-Pro-Phe-p-nitroanilide for its PPIase activity(Km=456.4 μmol/L;Vmax=1.981 U).CsA inhibited PPIase activity,showing lower micromolar inhibitory activity and binding affinity(Kd=5.122 μmol/L;IC50=1.004 μmol/L).Conclusions These results imply that CpCyP1 in the parasite may be the target for the previously reported anti-cryptosporidial efficacy of CsA and suggest that C.parvum cyclophilins could be evaluated as candidate drug targets.

ObjectiveTo explore the effectiveness and potential mechanism of Shugan Jianpi Granules (疏肝健脾颗粒) combined with Chushi Zhiyang Ointment (除湿止痒软膏) in the treatment of atopic dermatitis with sleep disturbance of liver constraint and spleen deficiency syndrome. MethodsSixty-six patients with atopic dermatitis combined with sleep disturbance of liver constraint and spleen deficiency syndrome were randomly divided into 33 cases each in the treatment group and the control group. Both groups were treated with Chushi Zhiyang Ointment for external use. The treatment group additionally received Shugan Jianpi Granules orally, one dose per day; and the control group received cetirizine hydrochloride tablets orally, 10mg per day, taken before bedtime. Both groups were under the treatment for 4 weeks. Clinical effectiveness was evaluated after treatment, and the SCORing Atopic Dermatitis (SCORAD) index, pruritus visual analog scale (VAS) score, Insomnia Severity Index (ISI) score, and Pittsburgh Sleep Quality Index (PSQI) score were recorded before and after treatment, and serum levels of melatonin (MLT), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-13 (IL-13), and tumor necrosis factor-α (TNF-α) were measured. The patients were also tested for blood routine, liver function and kidney function before and after treatment, and the occurrence of adverse events was also observed. ResultsThe total effective rate in the treatment group (90.63%, 29/32) was significantly higher than that in the control group (66.67%, 20/30, P<0.05). After the interventions, the scores for SCORAD, VAS, ISI, and PSQI, as well as the levels of IL-4, IL-6, IL-13, and TNF-α, were significantly reduced in both groups. In contrast, the MLT levels in treatment group significantly elevated compared to that before treatment (P<0.05). Comparing between the two groups after treatment, the scores of SCORAD, ISI, PSQI, and VAS, as well as the levels of serum IL-4 and IL-13 in the treatment group were significantly lower than those in the control group, while the MLT levels were markedly higher than that in the control group (P<0.05 or P<0.01). There was no obvious abnormality in blood routine, liver function and kidney function in both groups when compared before and after treatment. The incidence rate of adverse reactions was 9.38% (3/32) in the treatment group and 13.33% (4/30) in the control group, and the difference between groups showed no statistical difference (P>0.05). ConclusionOn the basis of topical application of Chushi Zhiyang Ointment, the combined application of Shugan Jianpi Granules can significantly alleviate the degree of skin lesions and itching, and improve the quality of sleep in atopic dermatitis patients with sleep disturbance of liver constraint and spleen deficiency syndrome, and its mechanism may be related to regulating the immune balance, reducing the secretion of inflammatory factors, and elevating the level of MLT.

Objective:To investigate the impact of different etiologies on the spatial distribution pattern of infarcts and the mapping pattern of focal symptoms in acute ischemic stroke (AIS) using a population-based standardized spatial analysis of MRI.Methods:This was a cross-sectional study. Clinical [age, sex distribution, admission National Institutes of Health Stroke Scale (NIHSS) score and 90-day modified Rankin Scale (mRS) score at discharge, etc.] and imaging data of 2 610 patients with AIS attending 9 Medical Centers from January 2015 to December 2021 were retrospectively analyzed. All patients were categorized into 1 718 cases of large artery atherosclerosis (LAA) type, 335 cases of cardioembolism (CE) type, and 557 cases of small artery occlusion (SAO) type according to TOAST typing. All patients underwent diffusion-weighted imaging, and the detected infarct lesions were segmented and aligned to the standardized space using artificial intelligence-assisted methods, and the spatial distribution frequency heatmaps of lesion locations in patients with different TOAST subtypes were plotted and compared with each other by χ2 test. Lesion-symptom image brain maps with different clinical symptoms were further plotted, and differences of lesion-symptom image relationships among different TOAST subtypes were observed and compared with each other by interaction effect. Results:In all patients, the favored sites of infarct lesions were the bilateral middle cerebral artery region in the anterior circulation and the occipital and brainstem regions in the posterior circulation. Compared with the LAA type, the CE type lesions were more likely to occur in the anterior cerebral artery region, the occipital lobe, and the cerebellum posterior, while the SAO type lesions were more likely to occur in the perforator artery supply area. The lesion-symptom mapping results showed that AIS patients with infarct lesions in the frontoparieto-temporal region in the presence of a left middle cerebral artery supply had higher admission NIHSS scores and higher discharge 90-day mRS scores for the LAA type than for the CE type( P<0.05); AIS patients with infarcted lesions in the brainstem region and some cerebellar regions in the presence of vertebrobasilar artery supply had higher admission NIHSS scores and higher discharge 90-day mRS scores for the CE type than for the LAA type( P<0.05). Conclusion:At the population level, brain mapping reveals specific infarct distribution patterns and differences in lesion-symptom mapping patterns of different etiologies AIS patients, providing imaging evidence for the understanding of AIS pathogenetic mechanisms and clinical management.

Objective:To investigate the diagnostic value of metagenomic next-generation sequencing (mNGS) for pyogenic spinal infections.Methods:A total of 255 patients diagnosed with pyogenic spinal infections were enrolled between September 2022 and September 2024 at Qingdao University Affiliated Hospital, Fuzhou Second General Hospital, First Affiliated Hospital of Nanchang University, Shandong University Affiliated Public Health Clinical Center, and the Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. Among them, 155 were male and 100 were female, with an average age of 62.5±14.2 years (ranging from 13 to 90 years). All patients had samples of infected tissue and/or pus collected for microbial culture and mNGS testing. The number, types, and positive rates of pathogens detected by microbial culture and mNGS were compared. Using culture results as the gold standard, receiver operating characteristic (ROC) curve analysis was performed for mNGS testing and the combined method of mNGS and microbial culture, calculating the area under the curve (AUC) and 95% CI. Results:All 255 cases were clinically diagnosed as pyogenic spinal infections, with 194 cases providing microbiological evidence. The most common Gram-positive bacterium was Staphylococcus aureus, while the most common Gram-negative bacterium was Escherichia coli. A total of 33 pathogenic microorganisms were detected by mNGS, while microbial culture detected 18 pathogenic microorganisms. The positive rate of mNGS was 72.2% (184 out of 255), which was significantly higher than that of 30.2% (77 out of 255) for microbial culture, showing a significant difference (χ 2=90.150, P<0.001); the positive rate of mNGS combined with microbial culture was 76.1% (194 out of 255) with significant difference compared to mNGS alone (χ 2=8.100, P<0.001). Among 178 culture-negative samples, the detection rate of mNGS was 65.7% (117 out of 178); among 77 culture-positive samples, the detection rate of mNGS was 87.0% (67 out of 77), and 97.0% (65 out of 67) of the detected pathogens matched the culture results at the species level. The AUCs of the ROC curves for mNGS testing and the combination of mNGS with microbial culture were 0.606 [95% CI (0.534, 0.678)] and 0.671 [95% CI (0.606, 0.736)], respectively, with significant differences compared to microbial culture ( P=0.007; P=0.007). Conclusions:mNGS demonstrates superior performance over conventional culture in identifying pathogens in pyogenic spinal infections. Moreover, combining mNGS with culture further improves diagnostic yield, supporting its integration into clinical practice.

Objective:To investigate the incidence of shoulder work-related musculoskeletal disorders (WMSDs) among occupational population in China, and to explore their intrinsic association with personal and work-related factors.Methods:In April 2024, 73497 valid questionnaires of the Chinese version of the Musculoskeletal Disorders Electronic Questionnaire were retrospectively analyzed from June 2018 to December 2023 in 22 provinces and 29 key industries in China, and the general information, occurrence of WMSDs and related risk factors of key occupational populations in different regions in China were collected. By using Chi-square test and confirmatory factor analysis, the relationship between shoulder fatigue and pain in key occupational groups and individual factors, work type, work posture and work organization was discussed, and the internal relationship was analyzed based on structural equation model.Results:Higher incidence of shoulder fatigue and pain were associated with female, lack of physical exercise, uncomfortable working posture and neck leaning forward ( P<0.05). Structural equation model analysis showed that work type, work posture and work organization were strongly correlated ( r=0.58, 0.55). Work organization and work type were strongly correlated with shoulder fatigue ( r=0.65) and moderately correlated with shoulder fatigue ( r=0.21). Shoulder fatigue was moderately associated with shoulder pain ( r=0.40). Individual factors, work type, work posture and shoulder fatigue could directly affect shoulder pain ( OR=0.07, -0.09, 0.17 and 0.40), and work type and work posture could also indirectly affect shoulder pain through shoulder fatigue ( OR=0.08, 0.03). Work organization only indirectly affected shoulder pain through shoulder fatigue ( OR=0.26) . Conclusion:The main influencing factor of shoulder pain is shoulder fatigue, followed by work posture and individual factors. Structural equation model can better reflect the complex relationship between work type, work posture and work organization and shoulder WMSDs. Improving work posture and work organization may be an effective way to control the influence of shoulder fatigue on shoulder pain.
