Interferon alpha-inducible protein 27 (IFI27) is an interferon alpha-inducible protein, which was found to be upregulated in some cancers, such as breast cancer, squamous cell carcinoma, hepatocellular carcinoma, and serous ovarian carcinoma. However, the role of IFI27 in ovarian cancer remains to be elucidated. This study was designed to investigate the role of IFI27 in ovarian cancer tumorigenicity. ⋯ These data suggested that IFI27 may be a potential target for developing novel diagnosis strategies and therapeutic interventions.

Observational Study
Plasma levels of high mobility group box 1 increase in patients with posttraumatic stress disorder after severe blunt chest trauma: a prospective cohort study.
High-mobility group box 1 (HMGB1), a key late mediator of systemic inflammation, is a potentially useful biomarker for predicting outcome in patients with severe blunt chest trauma. The purpose of this study was to define the relationship between plasma levels of HMGB1 and posttraumatic stress disorder (PTSD) in patients with severe blunt chest trauma. ⋯ In blunt chest trauma, plasma HMGB1 levels were significantly higher in patients with PTSD compared with patients with non-PTSD. Our data indicate that patients with high plasma levels of HMGB1 may be more prone to develop PTSD including acute and chronic PTSD.

Obesity is known to complicate trauma hospital stays. We hypothesize that obesity delays functional recovery in trauma patients. ⋯ Most trauma patients achieve full functional recovery some time after hospital discharge, but the recovery is delayed in obese patients and the delay is directly correlated with the severity of obesity.

Gallbladder cancer (GBC) is rare but the most common malignancy of biliary tract with a dismal prognosis. The early diagnosis and surgical treatment of GBC offers the only chance of long-term survival. Despite advances in radiological imaging, early diagnosis of GBC is still rarely achieved without histopathology. In our hospital, routine histologic examination of all resected gallbladder specimens has been standard practice. This study seeks to define whether selective histologic examination for gallbladder specimens based on preoperative imaging or intraoperative findings is justified. ⋯ Almost all cases of invasive GBC will show macroscopic abnormalities following examination by a simple procedure-a full dissection, inspection, and palpation of the gallbladder. Any patient with early GBCs "missed" on macroscopic examination can still receive the appropriate treatment by the cholecystectomy alone. The gallbladder should be sent for histology only if macroscopic examination raises suspicion. This selective policy is more cost-effective, and does not appear to compromise patients outcome.

Comparative Study
Effects of pyruvate-enriched peritoneal dialysis solution on intestinal barrier in peritoneal resuscitation from hemorrhagic shock in rats.
To investigate protective effects of pyruvate-enriched peritoneal dialysis solution (P-PDS), compared with lactate-PDS (L-PDS), on the intestinal mucosal barrier in peritoneal resuscitation (PR) from severe hemorrhagic shock (HS) in rats. ⋯ Pyruvate was superior to lactate in PDS in the correction of severe acidosis with PR. P-PDS was more preservative of expressions of intestinal ZO-1 and p-VASP and mucosal barrier function, compared with L-PDS in PR from severe HS in rats.
