Long non-coding RNA (long non-coding RNA, ln- cRNA) contains loci with transcriptional nucleotides of more than 200nt in length. As one group of the nucleotides that are similar to mRNA in molecular structure, but do not have the function of coding proteins due to the lack of open reading frame, IncRNA plays an important role in many molecular biological processes. LncRNA can express a lot of transcriptions. It has been found more than half of IncRNA highly expressed in central nervous system, and participated in maintaining normal brain function and inducing neuropsychiatric diseases, such as schizophrenia, autism and depression. Depression, as a complex and heterogeneous mental disease, is considered an important risk factor for disability and suicide. At the cellular and molecular levels, IncRNAs affect composition and function of certain specific nervous systems, such as hippocampal development and neuronal apoptosis, constituting relevant factors for the occurrence and development of depression. This article aims to review the variation characteristics of IncRNA in depression and to explore the potential possibility of IncRNA as diagnostic markers and therapeutic targets.

OBJECTIVETo perform a meta-analysis on clinical outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults.

METHODSPubmed database (from 1968 to March 2014), Cochrane library and CNKI database (from 1998 to March 2014) were searched. Case-control study on minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults were chosen,and postoperative infection, operative time, blood loss, fracture nonunion rate, delayed union,fracture malunion rate were seen as evaluation index for meta analysis. The system review was performed using the method recommended by the Cochrane Collaboration.

RESULTSTotally 5 studies (366 patients) were enrolled. Meta-analysis showed that there were significant meaning in postoperative infection between MIPPO and ORIF [OR = 0.23,95% CI (0.06,0.92), P = 0.04]; fracture nonunion rate in MIPPO was lower than in ORIF group [OR = 0.16, 95% CI (0.03,0.76), P = 0.02]; operative time in MIPPO was shorter than in ORIF group, and had significant difference [MD = -14.42, 95% CI (-27.79, -1.05), P < 0.05]; blood loss in MIPPO was less than in ORIF group [MD= -87.17,95%CI (-99.20, -75.15), P < 0.05]; there was no obviously meaning in delayed union between two groups.

CONCLUSIONFor distal tibial fractures in adults, MIPPO has, advantages of short operative time, less blood loss, lower incidence of infection and fracture non-uniom, but with high fracture malunion rate. MIPPO for distal tibial fractures in adults is better than ORIF, and the best treatment should choose according to patient's condition.

Objective·To establish a cell-based screening system for identification of compounds with activity in regulating retinoic acid receptor (RARα) stability. Methods·The modified pMSCV plasmid constructs, named as RARα-EGFP-IRES-DsRed, consists of enhanced green fluorescent protein (EGFP) fusing to RARα and red fluorescent protein (DsRed) as internal references incorporating the internal ribosome entry site (IRES) as interval sequence. The RARα-EGFP-IRES-DsRed plasmid was stably transfected into NB4 cells which were named as NB4-pMGIR-RARα. Fluorescence signals of EGFP and DsRed indirectly reflecting the expression of RARα, were detected by flow cytometry in cells that were treated with all-trans retinoic acid, sodium valproate, cytarabine, lenalidomide, etoposide, montelukast and gambogic acid, respectively. Effects of these compounds on the expression of RARα protein were further examined by Western blotting. Results·A double fluorescence reporter system for screening compounds that can increase the stability of RARα protein was successfully established, and sodium valproate was identified as a potent compound to promote the stability of RARα. Conclusion·The double fluorescence reporter system can be used to screen compounds regulating the stability of RARα protein, which can be further used to identify compounds regulating the stability of other proteins.
