Methods Fifty-two patients with metastasis 27 men and 25 women, were June 2003 Vol12 No2 treated from 1990 to 1999. Their average age was 56. 8 years (33 - 74). In 16 patients with multiple lesions, underwent surgery at bone shaft (29 patients) and bone epiphysis (26). Thirty patients were treated for pathologic fracture and the rest for impending fracture. Operations included limb-salvage (51 patients) and amputation (4) Limb salvage consisted of intralesional curettage (3 patients ), intramedullary nailing reconstruction (29 ), endoprosthesis ( 18 ), and temporary spacer ( 1 ). 21 patients accepted postoperative chemotherapy or radiotherapy. Results Follow-up of 52 patients for a mean of 28. 2 months (2 - 122 months) showed pain relief (41 patients), (75%) and full or part weight-bearing stability ( 36 ) 69 % . Local tumor recurrence occurred in 11 patients.展开更多

Emerging evidence indicated that many lncRNAs function in multiple biological processes and its dysregulation otten causes diseases. Recent studies suggested that almost all regulatory lncRNAs interact with biological macromolecules such as DNA, RNA, and protein. LncRNAs regulate gene expression mainly on three levels, including epigenetic modification, transcription, and posttranscription, through DNA methylation, histone modification, and chromatin remodeling. LncRNAs can also affect the development of diseases and tllerefore be used to diagnose and treat diseases. With new sequencing and microarray techniques, hundreds oflncRNAs involved in reproductive disorders have been identified, but their functions in these disorders are undefined. Data Sources: This review was based on articles published in PubMed databases up to July 10, 2017, with the tbllowing keywords: "long noncoding RNAs", "'LncRNA", "placentation", and "'reproductive diseases". Study Selection: Original articles and reviews on the topics were selected. Results: LncRNAs widely participate in various physiological and pathological processes as a new class of important regulatory/',actors. In spermatogenesis, spermatocytes divide and differentiate into mature spermatozoa. The whole process is elaborately regulated by the expression of phase-specific genes that involve many strains of lncRNAs. Literature showed that IncRNA in reproductive cumulus cells may contribute to the regulation of oocyte maturation, fertilization, and embryo development. Conclusions: LncRNA has been found to play a role in the development of reproduction. Meanwhile, we reviewed the studies on how lncRNAs participate in reproductive disorders, which provides a basis fbr the study of [ncRNA in reproduction regulation.展开更多
