Primary central nervous system lymphoma (PCNSL) is a rare form of extranodal non-Hodgkin's lymphoma and a limited number of cases have been reported from China. This study aimed to investigate the clinicopathological features of newly diagnosed PCNSLs from a single center in eastern China and to identify the potential prognostic factors for overall survival (OS) and progression-free survival (PFS). All consecutive patients with histopathologically diagnosed PCNSLs at our center between January 2003 and October 2017 were recruited.

This study established and analyzed the correlation between tumor location and clinical properties of glioblastomas in frontal and temporal lobes.
Methods: This retrospective study determined the location of glioblastomas in the frontal lobe (FL) or temporal lobe (TL) based on preoperative magnetic resonance imaging.
Long noncoding RNAs have recently been proven to regulate tumorgenesis in many cancers. However, their biological functions in glioblastoma remain largely unknown. Here we found an uncharacteristic lncRNA lncHERG that is highly expressed in human glioblastoma (GBM).

Investigated the possible correlations between tumor location and genetic alterations would enhance our understanding of gliomagenesis and heterogeneity of glioma. We examined mutations of TERTp and IDH by direct sequencing and fluorescence in-situ hybridization in a cohort of 225 grades II and III diffuse gliomas.

Purpose: How injured long-distance neural tracts are reestablished following ischemic brain injury remains unclear. Theories surrounding reconnection include the growth of newly formed axons from newborn neurons, modification of local circuits and a beneficial influence from neurotrophic factors. This research aimed to find the developing new born neurons and the neurotrophic factors they secreted in a middle cerebral artery occlusion (MCAO) rat model to explain the roles of neural progenitor cells in post-ischemic neurogenesis.

Methods: Controlled cortical impact (CCI) injury was performed in Sprague-Dawley rats and Nrf2-knockout or control mice. Sulforaphane (SFN), a potent Nrf2 activator, was used to activate Nrf2.
The implantation of neural stem cells (NSCs) in artificial scaffolds for peripheral nerve injuries draws much attention. NSCs were ex-vivo expanded in hyaluronic acid (HA)-collagen composite with neurotrophin-3, and BrdU-labeled NSCs conduit was implanted onto the ends of the transected facial nerve of rabbits. Electromyography demonstrated a progressive decrease of current threshold and increase of voltage amplitude in de-innervated rabbits after implantation for one, four, eight and 12 weeks compared to readouts derived from animals prior to nerve transection.

Methods: Multipotent neural stem cells (NSCs) and Schwann cells were harvested from the spinal cords of embryonic rats at 16 days post coitus and sciatic nerves of newborn rats, respectively. The differential characteristics of NSCs in vitro induced by either serum-based culture or co-culture with SC were analyzed by immunofluorescence.
Transplantation of neural stem cells (NSC) has shown to elicit functional recovery in experimental animal and human models of neural disorders pertaining to cell loss or degeneration. However, the underlying mechanisms of the regimen are not well understood. The scenarios lead to the speculation of neuroregeneration and replacement of lost neurons in both the central nervous system (CNS) and the peripheral nervous system (PNS).
