TRIM31 enhances chemoresistance in glioblastoma through activation of the PI3K/Akt signaling pathway.

Temozolomide (TMZ) resistance is a complication of treatment of glioma, and new strategies are urgently required to overcome chemoresistance in glioma cells. In the present study, it was demonstrated that tripartite motif-containing 31 (TRIM31) was abnormally upregulated in glioma tissues and cell lines compared with normal samples. Furthermore, the role of TRIM31 was assessed by overexpressing and knocking down its expression.

[Effects of Fulvic Acid on Absorption and Form Distribution of Heavy Metals on Sediments].

Based on the extracted fulvic acid (FA) from Lake Wuliangsuhai sediments by sequential alkali extraction, this work studied the effects of FA on the adsorption and fraction distribution of heavy metals (HM) on sediments using original sediments and sediments treated with 30% H₂O₂ as adsorbents. The results showed both organic matter and FA had effects on the HM adsorption onto sediments; The treatments of FA-free conditions and the sediments treated by H₂O₂ showed relatively strong influence on Cu²⁺ adsorption, which decreased the Cu²⁺ adsorption by 17.85%.

[Rapid pore cranial drilling and ventricular drainage in the treatment of ventricular hemorrhage caused by thalamic hemorrhage: an analysis of 401 cases].

Objective: To summarize the clinical efficacies and experiences of using rapid pore cranial drilling and external ventricular drainage (EVD) in the treatment of ventricular hemorrhage caused by thalamic hemorrhage.

Methods: Retrospective analysis was conducted for 401 patients at 5 hospitals from May 1983 to December 2010. They underwent EVD with an infusion of urokinase for intraventricular hemorrhage caused by thalamic hemorrhage.
