Gender, Age, and Concomitant Diseases of Colorectal Diverticulum in China: A Study of 7,964 Cases.

Aim: To analyze the epidemiological features of colorectal diverticulum (CRD) in China.

Methods: We retrospectively analyzed CRD patients in 8 tertiary hospitals located in 5 regions of China from 2000 to 2016. The detection rates, number and distribution, demographic information, concomitant disorders, and their associations were investigated.

Gene expression analysis of potential genes and pathways involved in the pathogenic mechanisms of parvovirus B19 in human colorectal cancer.

In order to investigate the pathogenic mechanisms of parvovirus B19 in human colorectal cancer, plasmids containing the VP1 or VP2 viral capsid proteins or the NS1 non-structural proteins of parvovirus B19 were constructed and transfected into primary human colorectal epithelial cells and LoVo cells. Differential gene expression was detected using a human genome expression array. Functional gene annotation analyses were performed using Database for Annotation, Visualization and Integrated Discovery v6.

[Expression of mouse lipopolysaccharide response protein LRP in E. coli and preparation of rabbit anti-mLRP serum].

Aim: To express mouse lipopolysaccharide response protein (mLRP) and prepare rabbit anti-mLRP serum.

Methods: The predicted mouse lrp cDNA sequence was obtained by splicing homologous ESTs by comparing human lrp cDNA with mouse ESTs. Then the primers were designed.
