Long non-coding RNAs (lncRNAs) are RNA transcripts longer than 200 nt without any protein coding ability. LncRNAs perform biological functions through a variety of mechanisms. They have a close association with human tumors, regulating the expression of genes at the epigenetic, transcriptional and post-transcriptional levels. LncRNAs are wildly involved in biological and pathological process and play a significant role in the development of cancer. This article reviews the research in the current status of lncRNAs in prostate cancer. Copyright © 2014 by TUMOR.

AIM: To evaluate the efficacy and safety of vitrectomy combined with internal limiting membrane ( ILM) peeling for treating foveoschisis in high myopia.

Articular cartilage repair is limited. Current treatments for cartilage defect are less satisfactory, and rarely restore full function or return the tissue to its native normal state. The rise of tissue engineering holds great promise for the generation of functional cartilage tissue substitutes. The history of cartilage tissue engineering and highlights the applications and advantages of various kinds of scaffolds in cartilage tissue engineering, such as native scaffolds, synthesis scaffolds, composite scaffolds and nanometer scaffolds had been introduced. But native scaffolds have weak strength and immunogenicity insufficiency, synthesis scaffolds degrade quickly, whose degrading products have cytotoxicity,which need further improvement. The application of superficial decoration overcomes the disadvantage of some scaffolds to an extend. Composite scaffolds possess the advantages of several scaffolds, it points out the direction of future scaffolds research. The development of Nanometer technique endows newly-synthesis scaffolds with nano-grade, thus it has some advantages and give a new way for the development of tissue engineering. At the end, the problems of these scaffolds, their trend of development and perspective studies were discussed.

Objective To investigate the status of wastewater treatment of hospital sewage in Jinan. Methods The indices of COD, NH3,N and PO43- in sewage discharged from 16 hospitals before and after treatment and the content of residual chloride and fecal coliform counts in treated sewage were monitored in 2002 in Jinan. The monitoring results were evaluated according to the Criteria for Wastewater Discharge (GB/T8978-1996) and compared with the analytic results obtained in the year 2001.
