ObjectiveTo study the effects of applying different microbial fertilizers on the growth and rhizosphere soil environment of Codonopsis pilosula and provide a theoretical basis for ecological cultivation of this medicinal plant. MethodsSeven groups were designed, including CK (no application of microbial fertilizer), T1 (Trichoderma longibrachiatum fertilizer), T2 (Bacillus subtilis fertilizer), T3 (Trichoderma viride fertilizer), T4 (compound microbial fertilizer), T5 (C. pilosula stems and leaves fermented with compound microbial fertilizer), and T6 (Scutellaria baicalensis stems and leaves fermented with T. viride fertilizer). The physiological indicators, yield, and quality of C. pilosula and the physicochemical properties, enzyme activities, and microbial diversity in the rhizosphere soil of different fertilizer treatments were measured. ResultsGroup T1 showed slight decreases in soluble protein content (SPC) and superoxide dismutase (SOD). Groups T2-T6 showed increases in physiological indicators such as proline (Pro), soluble solids content (SSC), SPC, catalase (CAT), and peroxidase (POD) and a decrease in malondialdehyde (MDA) in C. pilosula leaves. All the fertilizer treatments increased the yield of C. pilosula and the total polysaccharide content in the roots. T1, T2, T3, T4, and T5 increased the total flavonoid content in the roots. Meanwhile, T4 increased the total saponin content in the roots. All the fertilizer treatments reduced the pH and increased the electric conductivity (EC), soil organic matter (SOM), and alkaline nitrogen (AN) in the soil. T2 and T5 increased the available phosphorus (AP), and T3, T4, T5, and T6 increased the available potassium (AK) in the soil. All the fertilizer treatments increased the activities of urease, sucrase, and CAT in the soil. Except that T1 decreased the bacterial diversity in the soil, other fertilizer treatments significantly increased bacterial and fungal diversity in the soil. Different fertilizer treatments significantly affected the composition of bacterial and fungal communities in the soil. At the phylum level, the dominant bacterial phyla included Proteobacteria, Acidobacteriota, and Bacteroideta, and the dominant fungal phyla were Ascomycota, Mortierellomycota, and unclassified_fungi in the rhizosphere soil of C. pilosula after bacterial fertilizer treatment. At the genus level, unclassified Gemmatimonadaceae, Sphingomonas, and unclassified Vicinamibacteraceae were the dominant bacterial genera, while unidentified, unclassified Fungi, and unclassified Sordariomycetes were the dominant fungal genera in the rhizosphere soil. The results of redundancy analysis indicated that the main physicochemical factors affecting changes of microbial communities in the rhizosphere soil of C. pilosula were pH, EC, AK, AN, AP, and soil organic matter (SOM) in the soil. The correlation heatmap showed that Bryobacter had significantly positive correlations with EC, AK, and AN. There was a significantly negative correlation between Fusarium and SOM. In summary, applying an appropriate amount of microbial fertilizer can promote the growth and improve the rhizosphere soil environment of C. pilosula. ConclusionThe compound microbial fertilizer and the C. pilosula stems and leaves fermented with compound microbial fertilizer can improve the soil nutrients, growth, development, yield, and quality of C. pilosula, and thus they can be applied to the artificial cultivation of C. pilosula.

Objective Zinc finger protein 335 (Zfp335) plays a crucial role in the early development of thymic T cells and the differentiation of peripheral T cell subpopulations. The objective of this study is to investigate the role and underlying mechanisms of Zfp335 in the regulation of regulatory T cell (Treg) within tumor immunity. Methods The Zfp335 gene was specifically knocked out in Treg using tamoxifen (Zfp335fl/fl FOXP3creERT2), and the MC38 tumor model was established. On the 7th day after tumor inoculation, tumor size was observed and measured. Tumor size was monitored and recorded daily starting from day 7 post-inoculation. On day 12, tumors were harvested, and the proportions of CD4+ T cells, CD8+ T cells, and Treg were analyzed by flow cytometry. Additionally, the mitochondrial function of effector regulatory T cell (eTreg) was assessed. Results From day 10 post-tumor inoculation, tumor volume in the Zfp335CKO group was significantly reduced compared to that of the wild-type (WT) group. Furthermore, the infiltration of CD4+ and CD8+ T cells, along with their respective effector cells, was significantly higher in the Zfp335CKO group than in the WT group. The proportions of CD4+ and CD8+ T cells producing interferon-gamma (IFN-γ) and tumor necrosis factor-alpha (TNF-α) were also significantly increased in the Zfp335CKO group compared to that of the WT group. In addition, the percentage of CD8+ T cells secreting granzyme B (GzmB) was significantly higher in the Zfp335CKO group than that in the WT group. In contrast, the proportion of Treg and inducible T cell co-stimulator (ICOS)+ Treg in the Zfp335CKO group was significantly lower than that in the WT group. Finally, the expression level of Mitotracker Deep Red in eTreg from the Zfp335CKO group was significantly reduced compared to that in the WT group. Conclusion During tumorigenesis, the specific deletion of Zfp335 impairs Treg activation, which is related to decreased mitochondrial function in eTreg. In Zfp335CKO mice. Tumors exhibit increased infiltration of effector T cells, accompanied by elevated levels of cytotoxic cytokines, ultimately enhancing resistance to tumor progression.

Extracellular vesicles (EVs) are membrane-bound vesicles secreted by cells, including exosomes, microvesicles, and apoptotic bodies, which play critical roles in intercellular communication, material transport, and signal transduction. In recent years, increasing evidence has highlighted the essential function of EVs in early embryo development. By carrying bioactive molecules such as proteins, nucleic acids (e.g., mRNA and miRNA), and lipids, EVs regulate embryonic gene expression, cell proliferation, differentiation, and the microenvironment. Studies have shown that EVs derived from various segments of the female reproductive tract can enhance embryonic developmental potential, improve embryo quality, and facilitate implantation. Additionally, EVs secreted by embryos themselves participate in intercellular communication and play pivotal roles during embryogenesis. This review summarizes recent advances in understanding the functions of EVs in early embryo development, discusses their roles in mediating cell-cell communication and regulating gene expression, and explores their potential applica-tions in reproductive medicine and clinical practice, offering new perspectives for optimizing assisted reproductive technologies.

Autism Spectrum Disorders (ASDs) are reported as a group of neurodevelopmental disorders. The structural changes of brain regions including the hippocampus were widely reported in autistic patients and mouse models with dysfunction of ASD risk genes, but the underlying mechanisms are not fully understood. Here, we report that deletion of Trio, a high-susceptibility gene of ASDs, causes a postnatal dentate gyrus (DG) hypoplasia with a zigzagged suprapyramidal blade, and the Trio-deficient mice display autism-like behaviors. The impaired morphogenesis of DG is mainly caused by disturbing the postnatal distribution of postmitotic granule cells (GCs), which further results in a migration deficit of neural progenitors. Furthermore, we reveal that Trio plays different roles in various excitatory neural cells by spatial transcriptomic sequencing, especially the role of regulating the migration of postmitotic GCs. In summary, our findings provide evidence of cellular mechanisms that Trio is involved in postnatal DG morphogenesis.

Objective:To investigate the characteristics of brain network reorganization in migraine patients and its relationship with the grading of right-to-left shunt (RLS) in patent foramen ovale(PFO) by integrated 3.0T structural magnetic resonance imaging (MRI),resting-state functional MRI(fMRI),and contrast-enhanced transthoracic echocardiography, thereby toexplore the mechanism underlying cognitive impairment in migraine.Methods:A total of 49 migraine patients (migraine group)and 16 demographically matched healthy subjects (healthy control group) who received diagnosis and treatment at China-Japan Union Hospital of Jilin University from September 2020 to September 2023 were selected as the study participants. Structural images (T1-weighted) and resting-state functional images were obtained from brain imaging (MRI and fMRI) data. The amplitude of low-frequency fluctuation (ALFF) algorithm was used to quantify the intensity of spontaneous neural activity in brain regions, while the Fazekas scale and the Age-Related White Matter Changes (ARWMC) scale were employed to assess white matter lesions. Participants were evaluated using the Mini-Mental State Examination (MMSE). Based on the results of contrast-enhanced transthoracic echocardiography (cTTE),the migraine group was further subdivided into A1 group (18 cases, no PFO), A2 group (17 cases, PFO with small-to-moderate RLS) and A3 group (14 case, PFO with large RLS) group, the differences in brain functional activity and cognitive function were compared among these groups.Results:By Fazekas scale scores and ARWMC scale scores, the incidence of hyperintense foci in the deep white matter regions in the migraine group were higher than those in the healthy control group: 67.3%(33/49) vs. 6/16, 61.2%(30/49) vs. 5/16, there were statistical differences ( P<0.05). Compared with the healthy control group, the migraine group exhibited higher spontaneous neural activity intensity in the brainstem,bilateral posterior cingulate cortex,left medial frontal gyrus,and left middle frontal gyrus,while showing reduced brain activity in the right angular gyrus region. The short-term delayed recall scores and total MMSE scores in the migraine group were lower than thosein the healthy control group: (1.61 ± 1.06) scores vs. (2.44 ± 0.81) scores, (25.06 ± 2.31) scores vs. (27.94 ± 1.44) scores, there were statistical differences ( P<0.05). The short-term delayed recall scores mong the A1 group, A2 group and A3 group had statistical difference( P<0.05). Conclusions:Migraine patients exhibit specific brain functional network reorganization and cognitive dysfunction, which are closely related to the degree of RLS.
