Preoperative albumin levels predict prolonged postoperative ileus in gastrointestinal surgery.

Background: Prolonged postoperative ileus (PPOI) is a prolonged state of "pathological" gastrointestinal (GI) tract dysmotility. There are relatively few studies examining the influence of preoperative nutritional status on the development of PPOI in patients who underwent GI surgery. The association between preoperative albumin and PPOI has not been fully studied.

Nomogram to predict prolonged postoperative ileus after gastrectomy in gastric cancer.

Background: Prolonged postoperative ileus (PPOI) is one of the common complications in gastric cancer patients who underwent gastrectomy. Evidence on the predictors of PPOI after gastrectomy is limited and few prediction models of nomogram are used to estimate the risk of PPOI. We hypothesized that a predictive nomogram can be used for clinical risk estimation of PPOI in gastric cancer patients.

Retraction note to: Characterization of cancer stem-like cells in the side population cells of human gastric cancer cell line MKN-45.

Retraction Note to: J Zhejiang Univ-Sci B (Biomed & Biotechnol) 2013 Mar.; 14(3):216-223. This article has been retracted at the authors' request, as it contains large portions of text and figures that have been previously published in the following article: Zhang, H.

Characterization of cancer stem-like cells in the side population cells of human gastric cancer cell line MKN-45.

Objective: Side population (SP) cells may play a crucial role in tumorigenesis and the recurrence of cancer. Many kinds of cell lines and tissues have demonstrated the presence of SP cells, including several gastric cancer cell lines. This study is aimed to identify the cancer stem-like cells in the SP of gastric cancer cell line MKN-45.

Single purse string with four-point traction for better haemorrhoid retraction.

Background: Traction method is important to stapled haemorrhoidopexy (SH) for its impact on haemorrhoidal prolapse reduction. Single purse string with one-point traction is most commonly used in SH. This traction method often results in an irregular mucosal doughnut with inadequate height, which leads to insignificant and uneven haemorrhoidal prolapse reduction.
