Research Progress of Fibroblast Growth Factor Receptor Signaling Pathway in Breast Cancer / 中国医学科学院学报

Breast cancer,one of the common malignant tumors in women,has shown rising incidence in recent years,posing a serious threat to women's health.The advancement of molecular biology facilitates the revealing of the relationships between signaling pathways and breast cancer.Fibroblast growth factor receptor (FGFR) signaling pathway plays an important role in the proliferation,survival,differentiation,migration,and apoptosis of breast cancer cells.Strategies targeting the FGFR signaling pathway thus exhibit a promising prospect in breast cancer treatment.

Investigation on distribution of Yersinia enterocolitica in Henan province between 2005 and 2011 / 中华预防医学杂志

<p><b>OBJECTIVE</b>To investigate the distribution of Yersinia enterocolitica in Henan province from 2005 to 2011.</p><p><b>METHODS</b>A total of 6700 samples of stool specimen were collected from diarrhea patients and different domestic animals between 2005 and 2011 from Zhengzhou, Suixian and Dengfeng, as well as flies and the daub specimens of raw and cooked meat products. The bacteria were isolated by cold enrichment method, analyzed by the systematic biochemistry to determine the serotypes and bio-types, and tested the virulence genes by PCR method.</p><p><b>RESULTS</b>A total of 216 strains of Yersinia enterocolitica were isolated from 11 kinds of animal hosts and foods, while 29.63% (64/216) of them were from swine. The dominant epidemic serotypes of the Yersinia enterocolitica were O: 5 and O: 8, accounted for 23.2% (50/216) and 20.4% (44/216), respectively; type 1A was the dominant bio-type, accounted for 84.7% (183/216). The dominant serotype and bio-type differed a lot among various hosts.16 pathogenic strains were isolated from swine, followed by diarrhea patients (6 strains) and dogs (6 strains).</p><p><b>CONCLUSION</b>The distribution of the host of Yersinia enterocolitica was widespread, while swine was the dominant animal host.</p>
