Organotins in the aquatic media of secondary anabranches in the Three Gorges Reservoir Region, China.

The Three Gorges Reservoir Region (TGRR) is one of the most sensitive areas of ecological environment in China. As vital backwater areas, the secondary anabranches of the TGRR were prone to eutrophication in Spring which would affect the distribution and transfer of organotins (OTs) among aquatic media. This study quantified the concentrations of butyltins (BTs) and phenyltins (PhTs) in water columns and aquatic media of two anabranches of the TGRR, the Daning River (DR) and the Xiaojiang River (XR) during the state of eutrophication.

[Expression of c-myb in reflux esophagitis, Barrett esophagus and esophageal adenocarcinoma].

Objective: To investigate the expression of c-myb in reflux esophagitis, Barrett esophagus and esophageal adenocarcinoma.

Methods: The expression levels of c-myb in the esophageal mucosa tissue of patients with reflux esophagitis, Barrett esophagus and esophageal adenocarcinoma were detected by real-time fluorescent quantitative RT-PCR.

Results: The expression levels of c-myb mRNA in Barrett esophagus and esophageal adenocarcinoma tissues was significantly higher than that in normal and reflux esophagitis esophageal tissue (P<0.
