Objective:To characterize the vaginal flora of pregnant women during the second trimester using full-length 16S rRNA sequencing.Methods:A total of 142 pregnant women were systematically sampled from a pregnancy cohort. Vaginal swabs were collected for full-length 16S rRNA gene sequencing,and bioinformatics analysis was performed to characterize the vaginal microbiota and identify associated influencing factors.Results:Among the 142 pregnant women,the most frequently detected species were Lactobacillus iners(83.10%,118/142)and Lactobacillus crispatus(49.30%,70/142). The majority of samples(90.85%,129/142)were classified as Lactobacillus-dominant vagitypes,with the Lactobacillus iners vagitype accounting for 48.59%(69/142)and the Lactobacillus crispatus vagitype accounting for 38.73%(55/142). The vaginal microbiota was clustered into five community state types(CSTs):Ⅰa,Ⅰb,Ⅲa,Ⅲb,and Ⅳ. The most prevalent CSTs were Lactobacillus iners-dominated CST-Ⅲ(51.41%,73/142)and Lactobacillus crispatus-dominated CST-Ⅰ(24.65%,35/142). No samples were classified as CST-Ⅱ or CST-Ⅴ. A significant negative correlation was observed between Lactobacill and vaginosis-associated bacteria. Age,alcohol consumption,smoking,and vaginal treatments showed significant associations or trends toward significance with various Alpha diversity indices. Vaginal douching was associated with CST clustering,while obstetric history(primiparity,previous miscarriage history)was associated with vagitype classification. However,no significant associations were identified between maternal baseline characteristics and Beta diversity indices. Conclusions:Full-length 16S rRNA gene sequencing reveals that the vaginal microbiota of pregnant women is dominated by Lactobacillus iners and Lactobacillus crispatus. Maternal age,lifestyle factors such as smoking and alcohol consumption,and obstetric history are significantly associated with variations in vaginal microbiota composition.

Objective:
: The objective of this study was to assess the relationship between spermine synthase (SMS) expression, tumor occurrence, and prognosis in lower-grade gliomas (LGGs).
Methods:
: A total of 523 LGG patients and 1152 normal brain tissues were included as controls. Mann-Whitney U test was performed to evaluate SMS expression in the LGG group. Functional annotation analysis was conducted to explore the biological processes associated with high SMS expression. Immune cell infiltration analysis was performed to examine the correlation between SMS expression and immune cell types. The association between SMS expression and clinical and pathological features was assessed using Spearman correlation analysis. In vitro experiments were conducted to investigate the effects of overexpressing or downregulating SMS on cell proliferation, apoptosis, migration, invasion, and key proteins in the protein kinase B (AKT)/epithelialmesenchymal transition signaling pathway.
Results:
: The study revealed a significant upregulation of SMS expression in LGGs compared to normal brain tissues. High SMS expression was associated with certain clinical and pathological features, including older age, astrocytoma, higher World Health Organization grade, poor disease-specific survival, disease progression, non-1p/19q codeletion, and wild-type isocitrate dehydrogenase. Cox regression analysis identified SMS as a risk factor for overall survival. Bioinformatics analysis showed enrichment of eosinophils, T cells, and macrophages in LGG samples, while proportions of dendritic (DC) cells, plasmacytoid DC (pDC) cells, and CD8+ T cells were decreased.
Conclusion
: High SMS expression in LGGs may promote tumor occurrence through cellular proliferation and modulation of immune cell infiltration. These findings suggest the prognostic value of SMS in predicting clinical outcomes for LGG patients.

Objective :
To explore the effects and mechanisms of Kobophenol A ( KPA) on lipopolysaccharide ( LPS) -induced M1 macrophage polarization,and to provide a theoretical basis for the treatment of inflammatory immune diseases and the development of new drugs.
Methods:
The M1 macrophage polarization model of RAW264. 7 was established by LPS induction,and the peroxiredoxin 6 ( Prdx6) knockdown model was constructed using the Prdx6 inhibitor MJ33 and Prdx6-siRNA.RAW264. 7 cells,a mouse macrophage cell line,were treated with various concentrations of KPA. Cell viability was assessed using the CCK-8 assay.The expression levels of Prdx6 and M1 macrophage polarization-related proteins,including inducible nitric oxide synthase ( iNOS) and cyclooxygenase-2 ( COX-2) ,were detected by Western blot and immunofluorescence staining.The expression levels of Prdx6 and M1 macrophage polarization-related genes iNOS,interleukin-6 ( IL-6) ,and tumor necrosis factor α ( TNF-α) ,were measured by RT-qPCR. Flow cytometry was employed to detect the expression of cluster of differentiation 86 ( CD86) ,a marker of M1 macrophages.
Results:
Compared with the LPS-induced M1 macrophage polarization model , KPA significantly reversed the morphological changes of M1 macrophage polarization in RAW264. 7 macrophages and decreased the expression of M1 macrophage polarization-related proteins iNOS,COX- 2,CD86 and related genes iNOS,IL-6,TNF-α ( all P<0. 05) .In addition,LPS significantly downregulated the expression of Prdx6 in RAW264. 7 macrophages,while KPA upregulated the expression of Prdx6.Moreover,treatment with the Prdx6 inhibitor MJ33 significantly upregulated the expression of iNOS,a marker of M1 macrophage polarization,in RAW264. 7 macrophages,whereas treatment with KPA significantly downregulated the expression of iNOS ( all P<0. 05) .
Conclusion
KPA inhibits LPS-induced M1 polarization of RAW264. 7 macrophages by upregulating the expression of Prdx6.
