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

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.

Objective To assess the outcomes of ischemic stroke patients with atrial fibrillation (AF).Methods Six thousand six hundred and ninety-five patients with acute ischemic stroke,admitted to our hospital from May 2005 to December 2013,were recruited consecutively.These patients were divided into combined AF group (n=583) and non-combined AF group (n=6112).The clinical data,including stroke subtypes,stroke severity,risk factors of stroke,NIHSS scores and Barthel index,and outcomes,including mortality,unfavourable prognosis and recurrence at 3,12,and 36 months after stroke were analyzed.Results The prevalence rate of AF in the patients enrolled in this study was 8.7％ (583/6695).There was a higher frequency of AF in female than that in male,with significant difference (45.8％ vs.33.0％,P＜0.05).The patients from combined AF group were older than those without AF.The percentage of severe stroke in AF patients (34.8％) was significantly higher than that in non-combined AF group (8.3％,P＜0.05).The patients with AF were less likely than the patients without AF to have hypertension (63.8％ vs.73.3％),diabetes (24.9％ vs.32.3％),dyslipidemias (26.1％ vs.31.5％),artery stenosis (17.2％ vs.23.4％),current smoking (22.6％ vs.39.0％),and alcohol consumption (7.5 ％ vs.18.9％),with significant differences (P＜0.05).After adjusting age,gender,stroke subtype,and severity,and risk factors,multivariate analysis showed that there was a higher recurrence risk in combined AF group at 3 months after stroke than that in non-combined AF group (P＜0.05);patients with AF had significantly higher mortality,dependency,and recurrence rates at 12 and 36 months after stroke than those without AF (P＜0.05).Conclusion The long-term prognosis of patients with stroke complicated with AF is poor;therefore,normalized anticoagulant therapy should be taken to decrease the recurrence rate and burdens of stroke in China.
