MicroRNA profiles in five pairs of early gastric cancer tissues and adjacent non-cancerous tissues

Approximately half of the world''s gastric cancer cases and deaths occur in China. In addition, the incidence and mortality rates of gastric cancer in Gansu province in China are much higher than the average nationwide levels. The present study investigated microRNA (miRNA/miR) profiles in early gastric cancer (EGC) without specific symptoms. miRNA expression levels in five pairs of EGC tissues and adjacent non-cancerous mucosa tissues of patients from Gansu province in China were analyzed using a miRNA microarray. A total of 47 differentially expressed miRNAs (DEMs) were identified. Subsequently, mRNA expression profiles of three pairs of cancer tissues and adjacent non-cancerous tissues from 3 Asian patients with stage I or stage II gastric cancer (stage I/II; American Joint Committee on Cancer classification, Eighth Edition) were obtained from The Cancer Genome Atlas database, and differentially expressed genes (DEGs) were identified. The target genes of DEMs were filtered from the DEGs using the miRDB database and a miRNA-gene network was constructed. The functions of DEMs were evaluated using the tool for annotations of human miRNAs database, and via Gene Ontology analysis, Kyoto Encyclopedia of Genes and Genomes analysis and Gene Set Enrichment Analysis of the target genes. Finally, survival analyses of DEMs, which were in the miRNA-gene network, was performed. The results suggested that a number of miRNAs, including hsa-let-7a-5p, hsa-miR-27a-3p, hsa-miR-126-5p and hsa-miR-424-5p, may serve critical roles in EGC. The present study could provide a basis for the identification of EGC screening biomarkers. Furthermore, the present study may provide a basis for the exploration of the cause of the high incidence of gastric cancer in Gansu province from the perspective of miRNAs.     

2017年1-2月我国南方重点省份媒介伊蚊监测研究

目的 分析2017年1-2月我国南方重点省份媒介伊蚊监测资料,为以登革热为代表的媒介伊蚊传播疾病防控提供参考依据。方法 依据我国登革热中转支付项目媒介伊蚊监测系统上报的媒介伊蚊监测数据,分析研究期内南方重点省份媒介伊蚊的幼蚊密度（布雷图指数,BI）,筛选不同省份登革热传播不同风险等级的市或县（区）,并计算出不同省份媒介伊蚊控制水平达标率。结果 截至2017年2月,我国海南省平均BI达到登革热传播中风险;云南省景洪市、勐腊县城区、澜沧县口岸、耿马县清水河口岸、景洪告庄口岸BI超过5,存在由输入登革热病例引起暴发的风险。2017年云南省平均BI高于2016年同期水平,而海南省平均BI低于2016年同期水平。我国云南省BI控制达标率超过90%,而海南BI控制水平达标率不超过20%。结论 2017年1-2月,我国海南省平均BI达到登革热传播中风险,云南省重点地区城区和部分口岸BI达到低度风险。建议以海南、云南为代表的南方重点省份应继续加强媒介伊蚊监测、风险评估和控制工作,为我国媒介伊蚊传播疾病的科学防控提供依据。     

Isolation and phylogenetic analysis of porcine deltacoronavirus from pigs with diarrhoea in Hebei province,China

Porcine deltacoronavirus (PDC oV) is a recently identified coronavirus in the genus Deltacoronavirus that can cause enteric disease with clinical signs including diarrhoea, vomiting, dehydration and mortality in neonatal piglets. Although evidence of the prevalence of PDC oV in China is accumulating, little published information about Chinese PDC oV isolates is available. In this study, we investigated the presence of PDC oV in 49 faecal/intestinal samples from piglets with diarrhoea on different farms in Hebei province. Five samples (10.2%) were positive for PDC oV, but no coinfection of PDC oV with other enteropathogens was observed. A PDC oV strain named HB ‐BD was successfully isolated from the intestinal contents of a diarrhoeic piglet and serially propagated in swine testicular (ST ) cells for >40 passages. The complete genome of the HB ‐BD strain was sequenced and analysed. Genomic analysis showed that the HB ‐BD strain had a closer relationship with Chinese strains than those from other countries and was grouped within the Chinese PDC oV cluster. The results of this study will be valuable for further research of PDC oV genetic evolution and development of effective diagnostic reagents, assays and potential vaccines against newly emerged PDC oV strains.
