Morphological characteristics and phylogenetic analyses revealed two new species from China and a new record from Jilin Province of Agaricales.

In this study, we have found two new species- and . Phylogenetic analyses, based on the internal transcribed spacer regions (ITS) and the nuclear ribosomal RNA gene (nrLSU), suggest that the two new species are distinct and monophyletic. is distinguished from other species of the genus by the pileus covered with greyish-orange squamules in the centre, stipe light brown and surface covered with white triangular squamules.

Novel method for esophagojejunal anastomosis after laparoscopic total gastrectomy: semi-end-to-end anastomosis.

Aim: To test a new safe and simple technique for circular-stapled esophagojejunostomy in laparoscopic total gastrectomy (LATG).

Methods: We selected 26 patients with gastric cancer who underwent LATG and Roux-en-Y gastrointestinal reconstruction with semi-end-to-end esophagojejunal anastomosis.

Results: LATG with semi-end-to-end esophagojejunal anastomosis was successfully performed in all 26 patients.

Aberrant expression of Cx43 is associated with the peritoneal metastasis of gastric cancer and Cx43-mediated gap junction enhances gastric cancer cell diapedesis from peritoneal mesothelium.

The process of peritoneal metastasis involves the diapedesis of intra-abdominal exfoliated gastric cancer cells through the mesothelial cell monolayers; however, the related molecular mechanisms for this process are still unclear. Heterocellular gap-junctional intercellular communication (GJIC) between gastric cancer cells and mesothelial cells may play an active role during diapedesis. In this study we detected the expression of connexin 43 (Cx43) in primary gastric cancer tissues, intra-abdominal exfoliated cancer cells, and matched metastatic peritoneal tissues.

[Short-term efficacy of da Vinci robotic surgical system on rectal cancer in 101 patients].

Objective: To investigate the feasibility and safety of da Vinci robotic surgical system in rectal cancer radical operation, and to summarize its short-term efficacy and clinical experience.

Methods: Data of 101 cases undergoing da Vinci robotic surgical system for rectal cancer radical operation from March 2010 to September 2012 were retrospectively analyzed. Evaluation was focused on operative procedure, complication, recovery and pathology.

Autophagy protects against oxaliplatin-induced cell death via ER stress and ROS in Caco-2 cells.

Oxaliplatin is included in a number of effective combination regimens used as first and subsequent lines of therapy for metastatic colorectal cancer. Accumulating evidence indicates that autophagy plays a significant role in response to cancer therapy. However, the role of autophagy in oxaliplatin-induced cell death remains to be clarified.

Laparoscopy-assisted resection for gastric stump cancer and gastric stump recurrent cancer: a report of 15 cases.

Objective: This study was designed to investigate the technical methods and clinical therapeutic effects of laparoscopy-assisted resection of gastric stump cancer (GSC).

Methods: Laparoscopy-assisted resection was performed on 15 patients with GSC. The approach, method, difficult points, and techniques of the operation were analyzed, and its clinical therapeutic effect was evaluated.

[A modified method of laparoscopic side-to-side esophagojejunal anastomosis after laparoscopic total gastrectomy: a report of 12 cases].

Objective: To explore the method of alimentary reconstruction after laparoscopic total gastrectomy.

Methods: The clinical data of 12 patients undergone laparoscopic total gastrectomy and side- to- side esophagojejunal anastomosis from Feb. 2006 to Oct.

[Laparoscopic-assisted radical gastrectomy: a report of 105 cases].

Objective: To investigate the feasibility and safety of laparoscopic-assisted radical gastrectomy for gastric cancer.

Methods: One hundred and five patients with gastric cancer received laparoscopic-assisted radical gastrectomy, radical total gastrectomy were performed in 7 cases, proximal gastrectomy in 27 cases, proximal gastrectomy combined with splenectomy in 3 cases and distal gastrectomy in 68 cases.

Results: One hundred and five cases had laparoscopic-assisted radical gastrectomy successfully.

[Laparoscopy-assisted radical gastrectomy: a report of 71 cases].

Objective: To investigate the feasibility and safety of laparoscopy-assisted radical gastrectomy for gastric cancer.

Methods: Seventy-one patients with gastric cancer received laparoscopy-assisted radical gastrectomy for gastric cancer. Among them radical total gastrectomy was performed in 8 cases, proximal partial gastrectomy in 16 cases, proximal partial gastrectomy combined with splenectomy in 3 cases, and distal partial gastrectomy in 44 cases.
