Objective To describe the current situation of diarrhea in children under five years old in Nepal and to explore its influencing factors. Methods Data were collected from the open-access database, Nepal Demographic and Health Surveys in 2006, 2011 and 2016. Chi-square ( 2) and Wilcoxon rank sum test were used to compare difference of potential risk factors between groups with and without diarrhea. Multiple Logistic regression model was adopted to identify significant influencing factors on diarrhea in children under five years old in Nepal. Results In 2006, 2011 and 2016, the incidence of diarrhea children under five in Nepal was 12.3%, 13.3% and 6.8%, respectively. Univariate analysis of the potential influencing factors showed that there were significant differences in the gender, water source, toilet facilities and fuel type, age of children, age of mother when she gave birth to the child and education years of mother and children with and without diarrhea (all P<0.05). Multiple analysis revealed that improved toilet facilities (OR=0.874, 95% CI: 0.769-0.994, P=0.041) and the age of children(OR=0.613, 95% CI: 0.580-0.645, P<0.001) were protective factors of childhood diarrhea, and the risk of boys was higher than that of girls(OR=1.277, 95% CI: 1.147-1.423, P<0.001). Conclusions From 2006 to 2016, the incidence of diarrhea in children under five years old in Nepal was decreasing. Toilet facilities, age of children and gender of children were identified as the influencing factors of childhood diarrhea.

Objective To explore the inhibitory effects of miR-15 b-5 p on choroid melanoma cell line proliferation by targeting CDK4.Methods Dual-luciferase assay was used to verify the direct binding site between miR-15 b-5 p and CDK4 3'-UTR. MUM-2 B cells were cultured in vitro and transfected with negative control RNA, miR-15 b-5 p mimics, inhibitor normal control (nc) RNA, and miR-15 b-5 p inhibitor. qRT-PCR was used to detect miR-15 b-5 p expression, Western blotting was used to measure the expression levels of CDK4 in the cells, CCK-8 assay was used to detect proliferation capacity, and flow cytometry was used to detect cell cycle. Results Dual-luciferase assay verified that miR-15 b-5 p could bind to CDK4 mRNA 3'-UTR successfully. Compared to the negative control group, the mimics group showed significantly increased miR-15 b-5 p expression, decreased CDK4 levels, decreased cell proliferation rate, and increased proportion of G1-phase cells. Compared to the inhibitor nc group, the inhibitor group showed significantly decreased miR-15 b-5 p expression (t = 25.01, P < 0.000 1), increased CDK4 protein level, increased cell proliferation rate, and decreased proportion of G1-phase cells.Conclusion miR-15 b-5 p can target CDK4, induce G1 phase arrest in cells, and thus, reduce the proliferation rate of choroid melanoma cells.

PURPOSE: The purpose of this study was to investigate the survival trends and patterns of failure in patients with stage II nasopharyngeal carcinoma (NPC) treated with radiotherapy (RT) and chemotherapy over the last 20 years. MATERIALS AND METHODS: Thirty-eight hundred and eight patients diagnosed with stage II NPC between January 1990 and December 2012 were involved in this retrospective cohort study. All patients were treated with RT. According to the main imaging techniques and RT technology, we categorized these patients into four calendar periods: 1990-1996, 1997-2002, 2003-2007, and 2008-2012. Overall survival (OS), progression-free survival (PFS), locoregional relapse-free survival (LRFS), and distant metastasis–free survival (DMFS) were served as the clinical outcome. RESULTS: After a median follow-up period of 84.7 months, we observed increasing trends in survival and disease control. The 3- and 5-year OS rates increased from 87.1% and 78.7% in the first calendar period to 97.4% and 94.5% in the last calendar period, respectively (p<0.001). Additionally, significant increasing trends could be seen in the PFS and LRFS during the four calendar periods. In the subgroup analysis, the LRFS in patients older than 50 years at diagnosis showed greater improvement than younger patients. However, the rate of distant metastasis was stable and relatively low, as the 5-year DMFS ranged from 90.5% to 94.7% among the four calendar periods. CONCLUSION: The survival rates in patients with stage II NPC showed increasing trends from 1990 to 2012. The advance of RT provided excellent locoregional control and enhanced OS.

PURPOSE: The purpose of this study was to subdivide M1 stage nasopharyngeal carcinoma (NPC) patients with bone-only metastases for prognosis prediction while identifying the treatment effect of locoregional radiotherapy (LRRT) and metastasis radiotherapy (MRT) among patients with different risk. MATERIALS AND METHODS: From November 2006 to October 2016, a total of 226 patients with bone-only metastasic NPC were retrospectively enrolled. All patients developed distant lesions before receiving treatment. All potential prognostic factors were considered and the correlation of the M1 subdivisions with overall survival (OS) was determined by Cox regression hazards model. Kaplan–Meier curves were used to appraise survival condition and log-rank testing was used to compare the differences. RESULTS: The median follow-up time was 33.9 months (range, 3 to 126 months). According to multivariate Cox proportional hazard analysis, the number of metastatic lesions and Epstein-Barr virus (EBV) DNA status after palliative chemotherapy (PCT) were independent prognostic factors for OS. Thus, we subdivided patients into three risk groups according to these two factors. Systemic chemotherapy combined with LRRT may benefit patients in low- and intermediate-risk groups but not in the high-risk group. Further aggressive MRT based on systemic chemotherapy showed no survival benefit in any risk group. CONCLUSION: The stratification of NPC patients with bone-only metastasis based on EBV DNA after PCT and the number of metastatic lesions provided promising prognostic value and could aid clinicians in person-specific treatment.

Inulin has been used as a prebiotic to alleviate glucose and lipid metabolism disorders in mice and humans by modulating the gut microbiota. However, the mechanism underlying the alleviation of metabolic disorders by inulin through interactions between the gut microbiota and host cells is unclear. We use ob/ob mice as a model to study the effect of inulin on the cecal microbiota by 16S rRNA gene amplicon sequencing and its interaction with host cells by transcriptomics. The inulin-supplemented diet improved glucose and lipid metabolism disorder parameters in ob/ob mice, alleviating fat accumulation and glucose intolerance. The α diversity of gut microbial community of ob/ob mice was reduced after inulin treatment, while the β diversity tended to return to the level of wild type mice. Interestingly, Prevotellaceae UCG 001 (family Prevotellaceae) was obviously enriched after inulin treatment. A comparative analysis of the gene expression profile showed that the cecal transcriptome was changed in leptin gene deficiency mice, whereas the inulin-supplemented diet partially reversed the changes in leptin gene-related signaling pathways, especially AMPK signaling pathway, where the levels of gene expression became comparable to those in wild type mice. Further analysis indicated that Prevotellaceae UCG 001 was positively correlated with the AMPK signaling pathway, which was negatively correlated with markers of glycolipid metabolism disorders. Our results suggest that the inulin-supplemented diet alleviates glucose and lipid metabolism disorders by partially restoring leptin related pathways mediated by gut microbiota.

OBJECTIVE:
To analyze the molecular markers associated with occurrence, development and poor prognosis of acute myeloid leukemia (AML) by using the data of GEO and TCGA database, as well as multiomics analysis.
METHODS:
The transcriptome data meeting requirements were down-loaded from GEO database, the differentially expressed genes were screened by using the R language limma package, and the GO function enrichment analysis and KEGG pathway analysis were performed for differentially expressed genes, at the same time, the protein interaction network was contracted by using STRING database and cytoscape software to screen out the hub gene, then the prognosis analysis was carried out for hub gene by combination with the clinical information affected in TCGA database.
RESULTS:
620 differentially expressed genes were screened out, among which 162 differentially expressed genes were up-regulated, and 458 differentially expressed genes were down-regulated. Based on the results of GO functional enrichment, the KEGG pathway enrichment and protein interaction network, CXCL4, CXCR4, CXCR1, CXCR2, CCL5 and JUN were selected as hub genes. The survival analysis showed that the high expression of CXCL4, CXCR1, and CCL5 was a risk factor for poor prognosis of patiants.
CONCLUSION
CXCL4, CXCR1 and CCL5 can be used as biomarkers for the occurrence and development of AML, which relateds with the unfavorable prognosis and can provide a basis for further study.
