<b><i>Introduction:</i></b> Long-term disease duration of ulcerative colitis (UC) is known to increase the risk of developing colorectal cancer in adults; however, this association has not been genetically analyzed in children with UC. Herein, we examined the expression of cancer-related genes in the colonic mucosa of pediatric UC patients and their risk of developing colorectal cancer. <b><i>Methods:</i></b> Microarray analysis of cancer-related gene expression was conducted on rectal mucosa biopsy specimens randomly selected from pediatric cases, including 4 active-phase UC cases, 3 remission-phase UC cases, and 3 irritable bowel syndrome control cases. The subject pool was then expanded to 10 active-phase cases, 10 remission-phase cases, and 10 controls, which were analyzed by real-time polymerase chain reaction (PCR) and immunohistochemical staining. <b><i>Results:</i></b> The microarray results indicated significantly higher expression levels of cancer-related genes <i>PIM2</i> and <i>SPI1</i> in the active group than in the remission and control groups (<i>p</i> &#x3c; 0.05). Real-time PCR confirmed that <i>PIM2</i> and <i>SPI1</i> expression levels were significantly higher, whereas <i>TP53</i> and <i>APC</i> expression levels were significantly lower, in the active-phase group than in the remission and control groups (<i>p</i> &#x3c; 0.05). Immunohistochemical staining for PIM2, SPI1, TP53, and APC proteins supported the real-time PCR results. <b><i>Conclusions:</i></b> Expression levels of previously unreported cancer-related genes in adult UC patients were significantly higher in pediatric UC patients than in controls. Inflammation of the gastrointestinal mucosa increased the expression levels of cancer-related genes even in childhood-onset UC cases, suggesting that chronic inflammation from childhood may increase the risk of colorectal cancer development.

Background: Colorectal cancer (CRC) is the second leading cause of death worldwide, and distant metastasis is responsible for the poor prognosis in patients with advanced-stage CRC. RPS24 (ribosomal protein S24) as a ribosomal protein, multiple transcript variant encoding different isoforms have been found for this gene. Our previous studies have demonstrated that RPS24 is overexpressed in CRC. However, the mechanisms underlying the role of RPS24 in tumor development have not been fully defined. Methods: Expression of RPS24 isoforms and lncRNA MVIH in CRC tissues and cell lines were quantified by real-time PCR or western blotting assay. Endothelial tube formation assay was performed to determine the effect of RPS24 on tumor angiogenesis. The cell viability of HUVEC was determined by MTT assay, and the migration and invasion ability of HUVEC were detected by transwell assay. PGK1 secretion was tested with a specific ELISA kit. Results: Here, we found that RPS24c isoform was a major contributor to tumor angiogenesis, a vital process in tumor growth and metastasis. Real-time PCR revealed that RPS24c isoform was highly expressed in CRC tissues, while other isoforms are present in both normal and CRC tissues with no statistical difference. Moreover the change of RPS24 protein level is mainly due to the fluctuation of RPS24c. Furthermore, we observed that silencing RPS24c could decrease angiogenesis by inhibiting tubule formation, HUVEC cell proliferation and migration. Additionally, we investigated the molecular mechanisms and demonstrated that RPS24c mRNA interacted with lncRNA MVIH, the binding-interaction enhanced the stability of each other, thereby activated angiogenesis by inhibiting the secretion of PGK1. Conclusion: RPS24c facilitates tumor angiogenesis via the RPS24c/MVIH/PGK1 pathway in CRC. RPS24c inhibition may be a novel option for anti-vascular treatment in CRC.

Abstract Background: African swine fever (ASF) is the most important disease to the pigs and cause serious economic losses to the countries with large-scale swine production. Vaccines are recognized as the most useful tool to prevent and control ASF virus (ASFV) infection. Currently, the MGF505 and MGF360 gene-deleted ASFVs or combined with CD2v deletion were confirmed to be the most promising vaccine candidates. Thus, it is essential to develop a diagnosis method to discriminate wide-type strain from the vaccines used.Results: In this study, we established a duplex TaqMan real-time PCR based on the B646L gene and MGF505-2R gene. The sequence alignment showed that the targeted regions of primers and probes are highly conserved in the genotype II ASFVs. The duplex real-time assay can specifically detect B646L and MGF505-2R gene single or simultaneously without cross-reaction with other porcine viruses tested. The limit of detection was 5.8 copies and 3.0 copies for the standard plasmids containing B646L and MGF505-2R genes, respectively. Clinical samples were tested in parallel by duplex real-time PCR and a commercial ASFV detection kit. The detection results of these two assays against B646L gene were well consistent.Conclusion: We successfully developed and evaluated a duplex TaqMan real-time PCR method which can effectively distinguish the wide type and MGF505 gene-deleted ASFVs. It would be a useful tool for the clinical diagnosis and control of ASF.

Abstract The expression of galanin (GAL) and its three receptors (GalR1, GalR2, and GalR3) were studied with real-time PCR in the colonic wall of pigs suffering from experimental colitis caused by the infection with Brachyspira hyodysenteriae. The expression was studied in the muscular membrane, mucosa/submucosa layer, and in lymphocytes isolated from mucosa/submucosa. The expression levels were normalized to glyceraldehyde-6-phosphate dehydrogenase (GAPDH) expression and compared to expression levels in control animals. GAL expression was found in all three studied compartments of the colonic wall. A significant decrease in GAL expression level was found in the mucosa/submucosa and in isolated lymphocytes, whereas the decrease was much less profound in the muscular membrane. In the case of galanin receptors their expression was found in all studied compartments of the colonic wall, however at different levels, as compared to GAPDH expression. The decrease of galanin receptors expression was found in all studied compartments of the colonic wall of the sick animals.

Abstract Background Traditional Persian Medicine (TPM) is an ancient medical system that provides suggestions to improve the health of mothers and children during pregnancy and labor. Persian physicians believed that these instructions made labor easier, safer, and less painful. Methods The present randomized clinical trial was conducted among women at 33–38 weeks of pregnancy in Tehran, Iran. TPM instructions consisted of diet, bathing, and application of oil from the 38th week of pregnancy to the onset of labor. The primary outcome was the duration of the active phase of labor. Results The mean duration of the active phase was 331.60 ± 151.48 min for the intervention group and 344.40 ± 271.46 min for the control groups, but it was not statistically significant. The active phase was significantly shorter in women who had better compliance (p=0.03). The need for oxytocin augmentation was 53.3% in the control group and 38.5% in the intervention group (p=0.17). The rate of perineal infection was 13% in the control group and 0% in the intervention group (p=0.11). Conclusions The active phase was not different in the intervention and control groups, but it was shorter in compliant women. It is possible that prolonged use of these recommendations in combination with a sitz baths and a larger sample size could result in more significant outcomes.
