Irritable bowel syndrome (IBS) is the functional gastrointestinal disorder which has closely relationship with Central Nervous System (CNS). VN is the major connector between CNS and Enteric Nervous System (ENS). The aim of this study was to investigate the possible changes of dimension of Vagus Nerve (VN) with Vagus ultrasonography (VU) in IBS.

A total 119 patients which is consisted of 66 IBS patients appropriated with Rome IV criterias and 53 patients of control group were enrolled to the study. All patients were underwent to colonoscopy for role-out the organic pathologies, such as polyposis, inflammatory bowel syndromes, diverticulosis and colon cancer. Right Vagus (RV) and left Vagus (LV) nerve areas and diameters were calculated with VU.

There were no statistical difference of RV (p=0.445) and LV (p=0.944) diameter between two groups. There were also no statistical difference of RV (p=0.549) and LV (p=0.874) areas between IBS and control groups.

VU clearly depicted that there is no changes of dimension in VN areas and diameters in the IBS. This might show that VN is only a transporter of abnormal neuronal stimulations according to IBS pathophisiology.

Whereas colorectal cancer (CRC) is the third most common cancer worldwide, klotho gene has been reported as a tumor suppressor gene. Therefore, the aim of this study was to investigate the association between klotho (rs1207568 and rs564481) variants and CRC in Egyptian patients.

A case-control study comprising 100 patients with CRC and 100 age- and sex-matched healthy controls was conducted. Genotyping of klotho was performed by polymerase chain reaction with confronting two-pair primers.

The frequencies of the A allele of rs1207568 and the AC haplotype were significantly higher in patients with CRC than in the controls (p=0.019 and p=0.005, respectively).

We propose that klotho (rs1207568 and rs564481) variants play a significant role in colorectal carcinogenesis and that the klotho protein could be a target for oncotherapy.

This study aimed to investigate the differences and relevance of various common duodenal diseases in different parts in the aspects of age, gender, helicobacter pylori (H. pylori) infection, application of nonsteroidal anti-inflammatory drugs (NSAIDs), smoking, or alcohol consumption.

The medical records of various duodenal diseases were collected and tested for difference using the χ2 test or the Fisher exact probability method.

1) The proportions of duodenal ulcer (DU), inflammation, and duodenal bulb diseases in the adult group (A) (47.98%, 36.70%, and 66.63%) were higher than those in the elderly group (E) (41.38%, 29.83%, and 56.82%), but the proportions of duodenal diverticulum (DD) and tumor diseases in the descending and ascending segments (2.95%, 1.43%, 9.14%, and 0.14%) were lower than those in group E (13.73%, 3.69%, 19.41%, and 0.76%) (p<0.001). 2) The positive rate of H. pylori (63.64%) in the duodenal bulb diseases was higher than that in the bulb-descending segment (53.75%), but the application rate of NSAIDs (16.44%) in the duodenal bulb-descending diseases was lower than that in the descending segment (24.81%) (p<0.001).

1) DU, inflammation, and duodenal bulb diseases are common in adults, but DD and tumor diseases in the descending and ascending segments are more common in the elderly. 2) Compared with the duodenal bulb-descending diseases, the application of NSAIDs has greater impact on the diseases in the descending segment, and the rate of H. pylori infection is higher in duodenal bulb diseases.

To investigate the changes in the exosomes secreted by mouse dendritic cell line DC2.4 after infection with

and to analyze the possible regulatory mechanisms underlying such changes.

The exosomes were extracted by ultracentrifugation from DC2.4 cells at 28 h after infection with

. The morphology of the exosomes was examined with transmission electron microscopy, and the exosome size and density were determined using a nanoparticle tracker. High-throughput sequencing was carried out to identify the differentially expressed small RNAs in the exosomes derived from the infected cells.

infection resulted in a significantly increased density of exosomes secreted by DC2.4 cells. Small RNA sequencing revealed that

infection caused an increase in the number of miRNAs and piRNAs in the exosomes. The significantly up-regulated piRNAs after the infection included piR-mmu-159, piR-mmu-1526, piR-mmu-9082, piR-mmu-17405, and piR-mmu-25576.

infection causes accumulation and enrichment of exosomes secreted by DC2.4 cells with increased miRNAs and piRNAs in the exosomes.

To investigate the effect of β-arrestin1 overexpression on tumor progression in a NCG mouse model bearing T-cell acute lymphocytic leukemia (T-ALL) Molt-4 cell xenograft.

Molt-4 cells were tagged with firefly-luciferase (F-Luc) by lentiviral infection, and fluorescence intensity of the cells was detected using a luminescence detector. Molt-4 cell lines with β-arrestin1 overexpression or knockdown were constructed by lentivirus infection and injected

the tail vein in sub-lethal irradiated NCG mice. Body weight changes and survival time of the xenografted mice were observed, and the progression of T-ALL in the mice was evaluated using an

fluorescence imaging system. Sixteen days after xenografting, the mice were euthanatized and tumor cell infiltration was observed in the slices of the liver and spleen.

We successfully tagged Molt-4 cells with F-Luc and overexpressed or knocked down β-arrestin1 in the tagged cells. Bioluminescent imaging showed obvious luminescence catalyzed by F-Luc in Molt-4 cells.
