Sialic acid-based probiotic intervention in lactating mothers improves the neonatal gut microbiota and immune responses by regulating sialylated milk oligosaccharide synthesis via the gut-breast axis.

Human milk oligosaccharides (HMOs) are vital milk carbohydrates that help promote the microbiota-dependent growth and immunity of infants. Sialic acid (SA) is a crucial component of sialylated milk oligosaccharides (S-MOs); however, the effects of SA supplementation in lactating mothers on S-MO biosynthesis and their breastfed infants are unknown. Probiotic intervention during pregnancy or lactation demonstrates promise for modulating the milk glycobiome.

Alterations of milk oligosaccharides in mothers with gestational diabetes mellitus impede colonization of beneficial bacteria and development of RORγt Treg cell-mediated immune tolerance in neonates.

Gestational diabetes mellitus (GDM) is an increasing public health concern that significantly increases the risk of early childhood allergic diseases. Altered maternal milk glycobiome may strongly affect gut microbiota and enteric-specific Treg cell-mediated development of immune tolerance in GDM infants. In this study, we found that, compared with healthy Chinese mothers, mothers with GDM had significantly lower levels of total and specific human milk oligosaccharides (HMOs) in their colostrum that subsequently increased with extension of lactation.

Prediction of a miRNA-mRNA functional synergistic network for cervical squamous cell carcinoma.

Cervical squamous cell carcinoma (CSCC) accounts for a significant proportion of cervical cancer; thus, there is a need for novel and noninvasive diagnostic biomarkers for this malignancy. In this study, we performed integrated analysis of a dataset from the Gene Expression Omnibus database to identify differentially expressed genes (DEGs) and differentially expressed miRNAs (DEmiRNAs) between CSCC, cervical intraepithelial neoplasia (CIN) and healthy control subjects. We further established protein-protein interaction and DEmiRNA-target gene interaction networks, and performed functional annotation of the target genes of DEmiRNAs.

Synchronous leiomyosarcoma and fibroma in a single ovary: A case report and review of the literature.

Primary ovarian leiomyosarcoma (POLMS) is a rare disease. To the best of our knowledge, only 72 cases, including the present case, have been reported in the English literature, while synchronous POLMS and fibroma in a single ovary have not previously been reported at all. In the present study, a 46-year-old premenopausal woman was diagnosed with a mass in the left ovary in 2005.

Increased expression of human macrophage metalloelastase (MMP-12) is associated with the invasion of endometrial adenocarcinoma.

To evaluate the association between the expression of human macrophage metalloelastase (matrix metalloproteinase-12, MMP-12) with cancer invasion and differentiation of endometrial adenocarcinoma, specimens from endometrial adenocarcinoma (n=61) of diverse stages and histologic types were collected from patients having undergone hysterectomy, and specimens from normal endometrium (n=38) were obtained from patients with benign diseases. The expression of MMP-12 was analyzed immunohistochemically, by Western blot, and RT-PCR. The positive rate of MMP-12 was significantly increased in endometrial adenocarcinoma (81.

[Transfection and expression of hRI gene on human umbilical blood stem cells and gene therapy for mouse melanoma].

In order to explore the transfection and expression of hRI gene on human umbilical blood stem cells, and observe it's effect on the tumor growth. After enriching human umbilical cord blood CD34+ cells with a high-gradient magnetic cell sorting system (MACS), transfected them with supernatant of retrovirus containing human Ribonuclease inhibitor (hRI) cDNA. Hematopoietic progenitor clonogenic assay and PCR were used to evaluate transfection efficiency, and Western-blot and immune fluorescence were used to evaluate the expression quantity of hRI gene after transfection.
