Curcumin induces G2/M arrest and triggers apoptosis via FoxO1 signaling in U87 human glioma cells.

It has previously been demonstrated that curcumin possesses an antitumor activity, which is associated with its ability to induce G2/M cell cycle arrest and apoptosis. However the detailed underlying mechanisms remain unclear. The present study aimed to investigate the efficacy and underlying mechanism of curcumin‑induced cell cycle arrest and apoptosis in U87 human glioblastoma cells.

[Comparison of three fixations for treatment of intertrochanteric femoral fractures in the elderly].

Objective: To compare the clinical effects of three internal fixations as follows:dynamic hip screw (DHS), proximal femoral nail-A (PFNA) and InterTAN, for intertrochanteric femoral fractures in elderly patients.

Methods: From February 2007 to May 2012,136 elderly patients with intertrochanteric fractures (including 71 males and 65 females, ranging in age from 60 to 88 years old with an average of 69 years old) were treated with DHS (group A, 80 cases), PFNA (group B, 36 cases) and InterTAN (group C, 20 cases). Statistical analysis were applied to compare the 3 groups in operative time, blood loss, fracture healing time, intrraoperative complications and functional outcome (Harris hip score).
