Objective To explore the effects of aberrant O-glycosylation modifications induced by the knockout of Cosmc or T-synthase genes on the expression profiles of miRNAs in exosomes derived from colorectal cancer cells and to reveal the molecular mechanisms of O-glycosylation in the development of colorectal cancer and identify potential biomarkers for early diagnosis and treatment.Methods This research specifically targets the Cosmc or T-synthase genes in the human colorectal cancer cell line HCT116 to create stable cell lines exhibiting abnormal O-glycosylation with CRISPR/Cas-9 gene editing technology.Exosomes originating from these colorectal cancer cells were isolated and authenticated.A microarray chip equipped with primer sequences for 16 miRNAs closely associated with colorectal cancer was employed to assess the differential expression of miRNAs within these exosomes with fluorescent quantitative polymerase chain reaction(PCR).And then,a cohort of miRNAs that exhibited significant and consistent changes in expression levels across the exosomes from both cell lines was selected.These miRNAs were further validated independently with traditional fluorescent quantitative PCR.Subsequently,data from The Cancer Genome Atlas Program(TCGA)database containing patient information on colorectal cancer was harnessed.Employing R programming language,Gene Set Enrichment Analysis(GSEA)was conducted on the upregulated miRNA to investigate the downstream pathways significantly impacted and the malignant biological behaviors they may influence.Results The absence of either Cosmc or T-synthase genes results in the dysregulation of O-glycosylation in colorectal cancer cells,leading to the exposure of Tn antigens.This,in turn,affects the expression levels of specific miRNAs in exosomes derived from these cells.Specifically,the expression of hsa-miR-125b-1-3p was downregulated,while that of hsa-miR-218-5p was upregulated.Notably,hsa-miR-218-5p were found to be closely associated with the epithelial-mesenchymal transition(EMT)process in tumor cells,which is a key mechanism in cancer progression.Conclusion It elucidates that the aberrant O-glycosylation mediated by the knockout of Cosmc or T-synthase genes significantly influences the expression of certain miRNAs in exosomes from colorectal cancer cells,potentially affect the EMT process in colorectal cancer and thereby promoting distant metastasis.Given the inherent stability and detectability advantages of colorectal cancer-derived exosomes,the altered expression levels of miRNAs within these exosomes may serve as indicators of the stated of abnormal O-glycosylation in colorectal cancer.These findings suggest that exosomal miRNAs have potential as biomarkers for monitoring disease progression and therapeutic efficacy.Consequently,this could pave the way for more personalized diagnostic and treatment strategies tailored to individual colorectal cancer patients,enhancing the precision and effectiveness of clinical management.

Objective: This study aimed to explore the relationships between various exercise components (frequency, intensity, duration) and social anxiety. Methods: A sample of 844 college students in China participated in this study. The Physical Activity Rating Scale-3 assessed participants’ daily physical activity. Social anxiety levels were measured using the Liebowitz Social Anxiety Scale. A questionnaire was developed to collect demographic information and examine the relationships between exercise components and social anxiety levels. Results: One-way analysis of variance revealed significant differences in social anxiety levels across varying physical activity intensities. Specifically, students engaging in high levels of physical activity exhibited the lowest social anxiety. Post hoc analyses identified that exercise frequency F3 (p<0.01), exercise duration D5 (p<0.01), and exercise intensity I3 (p<0.01) were significantly associated with the lowest social anxiety levels. Among these components, regression analysis indicated that exercise duration (p<0.01) had the most substantial impact on social anxiety levels, followed by exercise frequency (p<0.05). In contrast, exercise intensity (p>0.05) did not significantly affect social anxiety levels. Conclusion The most influential factors associated with decreased social anxiety were: 1) moderate to high exercise intensity, 2) exercise duration of at least one hour, and 3) exercise frequency of at least 1–2 times per week. Among these factors, exercise duration and frequency demonstrated significantly stronger associations with reduced social anxiety. Therefore, it is advisable to prioritize exercise duration and frequency in physical activity programs for college students to reduce social anxiety and achieve more substantial outcomes.

ObjectiveTo establish a quality evaluation method for Zhuye Shigao granules（Zhuye Shigaotang） based on fingerprint and determination of index components， and to investigate the therapeutic effect of Zhuye Shigao granules on mice with cold-dampness pestilence attacking lung syndrome. MethodsThe fingerprint of Zhuye Shigao granules was established by high performance liquid chromatography（HPLC）， and the methods for determination of total calcium， orientin， isoorientin， ginsenosides Rg₁， Re and Rb₁ and other 2 index components were established. Fifty ICR mice were randomly divided into the blank group， model group， Zhuye Shigao granules low， medium and high dose groups（9.3， 18.6， 37.2 g·kg^-1·d^-1）， with 10 mice in each group. In addition to the blank group， the model mice with cold-dampness pestilence attacking lung syndrome was prepared by nasal drip of lipopolysaccharide combined with cold-dampness environment. Each administration group was given the corresponding liquid by gavage according to the dose， while the blank group and model group were given the same volume of normal saline by gavage. Then， the body temperature and organ index of mice in each group were measured， hematoxylin-eosin（HE） staining was used to investigate the lung tissue injury of mice in each group， and enzyme-linked immunosorbent assay（ELISA） was used to detect the changes of tumor necrosis factor-α（TNF-α）， interleukin（IL）-lβ， IL-6， IL-10 levels in serum and lung tissue， as well as immunoglobulin（Ig）A and IgM levels in serum. ResultsThe fingerprint similarity of 10 batches of Zhuye Shigao granules was>0.950， and 20 common peaks were calibrated. Seven of them were identified， including peak 11（isoorientin）， peak 12（orientin）， peak 14（apioside liquiritin）， peak 15（liquiritin）， peak 17（apioside isoliquiritin）， peak 19（isoliquiritin） and peak 20（liquiritigenin）. The results of quantitative analysis showed that the content range of each index component in 10 batches of Zhuye Shigao granules was as follows：Total calcium of 9.978-11.294 mg·g^-1， isoorientin of 0.033-0.041 mg·g^-1， orientin of 0.046-0.055 mg·g^-1， ginsenoside Rg₁+ginsenoside Re of 0.748-0.762 mg·g^-1， ginsenoside Rb₁ of 0.151-0.197 mg·g^-1， liquiritin of 1.106-1.366 mg·g^-1， glycyrrhizic acid of 0.904-1.182 mg·g^-1_. Compared with the blank group， the body temperature of mice in the model group was significantly increased， the organ indexes of liver， lung and spleen were significantly decreased， the organ index of thymus was significantly increased， HE staining of lung tissue showed infiltration of inflammatory cells， a small amount of serous exudation was observed in the alveoli， and lung tissue was damaged. After the intervention of Zhuye Shigao granules， the pathological changes were improved compared with the model group. The expression levels of IL-1β， IL-6 and TNF-α were significantly increased， the expression level of IL-10 was significantly decreased in serum and lung tissue. The levels of IgA and IgM in serum were significantly decreased（P<0.01）. Compared with the model group， the body temperature， the organ indexes and immune factor levels in serum and lung tissue of mice in the Zhuye Shigao granules medium and high dose groups were significantly reduced（P<0.05， P<0.01）. ConclusionIn this study， the quality evaluation of Zhuye Shigao granules was carried out based on fingerprint combined with determination of index components， and the fingerprint of four herbs（Lophatheri Herba， Ophiopogonis Radix， Pinelliae Rhizoma and Glycyrrhizae Radix et Rhizoma） in this formula and the determination of 8 index components were established. The therapeutic effect of Zhuye Shigao granules on mice with cold-dampness pestilence attacking lung syndrome may be related to inhibiting inflammatory response and mediating immune regulation.
