BACKGROUND： Stathmin is a ubiquitous cytosolic regulatory phosphoprotein and is overexpressed in different human malignancies. The main physiological function of stathmin is to interfere with microtubule dynamics by promoting depolymerization of microtubules or by preventing polymerization of tubulin heterodimers. Stathmin plays important roles in regulating many cellular functions as a result of its microtubuledestabilizing activity. Currently, the critical roles of stathmin in cancer cells, as well as in lymphocytes have been valued. This review discusses stathmin and microtubule dynamics in cancer development, and hypothesizes their possible relationship with epithelial-mesenchymal transition（EMT）.DATA SOURCES： A PubMed search using such terms as ＂stathmin＂, ＂microtubule dynamics＂, ＂epithelial-mesenchymal transition＂, ＂EMT＂, ＂malignant potential＂ and ＂cancer＂ was performed to identify relevant studies published in English.More than 100 related articles were reviewed.RESULTS： The literature clearly documented the relationship between stathmin and its microtubule-destabilizing activity of cancer development. However, the particular mechanism is poorly understood. Microtubule disruption is essential for EMT, which is a crucial process during cancer development. As a microtubule-destabilizing protein, stathmin may promote malignant potential in cancer cells by initiating EMT.CONCLUSIONS： We propose that there is a stathminmicrotubule dynamics-EMT（S-M-E） axis during cancer development. By this axis, stathmin together with itsmicrotubule-destabilizing activity contributes to EMT, which stimulates the malignant potential in cancer cells.
Pancreatic fistula is one of the most common complications after the distal pancreatectomy.Many methods have been tried to solve the problem,but no one is optimal,especially for the soft pancreatic stump cases.This study used ligamentum teres hepatis as a patch to cover the pancreatic stump.Between October 2010 and December 2012,seventyseven patients who had undergone distal pancreatectomy with a soft pancreatic stump were divided into two groups:group A(n=39,patients received conventional ligated main pancreatic duct method)and group B(n=38,patients underwent a coverage procedure).Patients in group A had a longer recovery from postoperative pancreatic fistula than those in group B(16.4±3.5 vs 10.8±1.6 days,P<0.05).The coverage procedure with ligamentum teres hepatis is a safe,effective and convenient method for patients with a soft pancreas remnant during distal pancreatectomy.
