The response of Pyropia haitanensis to inorganic arsenic under laboratory culture.

Up to now, complicated organoarsenicals were mainly identified in marine organisms, suggesting that these organisms play a critical role in arsenic biogeochemical cycling because of low phosphate and relatively high arsenic concentration in the marine environment. However, the response of marine macroalgae to inorganic arsenic remains unknown. In this study, Pyropia haitanensis were exposed to arsenate [As(V)] (0.

[Influences of the phosphorylation of p38 mitogen activated protein kinase on gene expression of tumor necrosis factor-alpha in multiple organ dysfunction syndrome in pigs].

Objective: To investigate that the phosphorylation of the p38 mitogen activated protein kinase (p38MAPK) influences gene expression of tumor necrosis factor-alpha (TNF-alpha) in multiple organ dysfunction syndrome (MODS) in pigs.

Methods: Thirty pigs were divided into MODS group and control group, and an animal model of MODS of "two-hit" injury, including hemorrhagic shock and endotoxemia, was reproduced. The content of p38MAPK's phosphorylation was assessed with Western blotting.

[Resection of pancreatic capsule and anterior layer of transverse mesocolon in radical gastrectomy and its clinical significance].

Objective: To investigate the clinical significance of resection of the pancreatic capsule and anterior layer of transverse mesocolon in radical gastrectomy.

Methods: Between January 2007 and July 2008, a total of 213 gastric cancer patients enrolled in the study. These patients were randomly assigned into two groups: 105 in group R and 108 in group N.

Clinical management of abdominal trauma.

Objective: To improve the prognosis of patients with abdominal trauma.

Methods: Between January 1993 and December 2005, 415 patients were enrolled in this research. The patients consisted of 347 males and 68 females with mean age of 36 years (ranging from 3-82 years).

[Efficacy of intraoperative hypotonic peritoneal chemo-hyperthermia combined with early postoperative intraperitoneal chemotherapy on gastric cancer].

Background & Objective: Abdominal recurrence from exfoliated cancer cells contributes a lot to treatment failure of advanced gastric cancer. Intraperitoneal chemotherapy, which has been proved effective in eliminating exfoliated cancer cells in abdominal cavity, is a hot topic on treatment of gastric cancer. This study was to explore application of combined therapy of intraoperative hypotonic peritoneal chemo-hyperthermia and early postoperative intraperitoneal chemotherapy to gastric cancer.

Prospective evaluation of magnetic resonance cholangiography in patients with suspected common bile duct stones before laparoscopic cholecystectomy.

Objective: To evaluate the predictive value of magnetic resonance cholangiography (MRC) in selected patients before laparoscopic cholecystectomy (LC).

Methods: Patients with risk factors for common bile duct (CBD) stones scheduled for elective LC from March 1999 to May 2001, underwent MRC followed by endoscopic retrograde cholangiography (ERC) to detect the stones and the accuracy of MRC. Selection of suspected patients was based on clinical, ultrasonographic, and laboratory criteria.
