ABSTRACT
Giant cell tumour of bone is one of the most common primary musculoskeletal tumours,accounting for 10％-21％ of bengin bone tumours,which can behave like malignant tumors and have benign histologic characteristics.Giant cell tumour (GCT) of bone is classified by the World Health Organisation (WHO) as a benign but locally aggressive tumour.Intralesional excision and wide resection may be helpful in operative treatment for GCT.However,there are limitations with these options in spite of the use of adjuvant therapy.For instance,intralesional excision had more local recurrence rate and less complications,wide resection had less local recurrence and poor functional results.Therefore,there is no widely held consensus regarding the ideal treatment selection for all GCT patients.The purpose is to review literature reports on the morphological features of GCT of bone and existing surgical method,and discuss the relationship between morphology characteristics of GCT and the selection of surgical options and postoperative recurrence rate,in order to help oncological doctors to choose surgical method in the clinical practice.
ABSTRACT
Objective To study the apo-E gene polymorphisms and the lipoprotein level character of different gene expression in patients with cerebrovascular infarction(CI) and intracerebral hemorrhage(ICH).Methord With case-control study method,the apo-E gene expression,its allele frequency and the levels of serum lipids in patients with cerebrovascular infarction or with intracerebral hemorrhage and the control were compared.Result The CI group had a higher apo-E ?4 allele frequency(10%) than controls(4.6%)(P
