Bonetumorisonekindofmalignanttumorwhichthreatslifeamongchildrenandadoles-cent.Osteosarcoma (OS ) and Ewing sarcoma (ES ) have been paid much attention by medical community because of their complex occurrence,development,metastasis mechanism and poor prognosis.The research showed that activation of protooncogene and mutation of suppressor gene,absence of apoptosis signal and hypox-ia-inducible factor (HIF)all participated in the occurrence,development and metastasis of OS and ES.It is suggested that clarified pathomechanism of bone tumors could provide more effective therapeutic strategies and lower the mortality of patients.

Objective To explore the roles of biomarkers of the ratios of microRNA (miRNA)in osteosarcoma.Methods The blood samples from 20 patients with osteosarcoma and 30 healthy people with similar age were choosed.The miRNA expression profiles were filtered by gene chips of high flux.The results were verified by qRT-PCR.The miRNA expression ratio was analysed by receiver operating characteristic (ROC)curve aiming to find the most predictive potential combination-type markers.Results Two hundred and fifty-eight miRNAs were found to be significantly deregulated in blood samples from 30 patients with osteo-sarcoma as compared with their matching normal blood samples (F=5.564,P<0.05).Four miRNAs were choosed from blood samples of22 patients with osteosarcoma and normal blood samples.MiR-181b,miR-199b-5p and miR-451 were significantly higher than that in normal blood sample (F=6.283,P<0.05),while miR-124 showed low expression (F=7.201,P<0.05).Furthermore,the ratio of miR-199b-5p/miR-124 showed a high sensitivity (96%)and specificity (97%).Conclusion The abnormal expression of miRNA in osteosar-coma makes it have a predictive effect.The ratio of miR-199b-5p/miR-124 could be served as combination-type biomarkers in the diagnosis of osteosarcoma.

BACKGROUND: Repetitive brief and non-lethal cerebral ischemia can produce cumulative neuronal damage and vascular dementia; however, precisely injured patterns and mechanisms are still unclear. Thalamus is an important structure of learning and memory; meanwhile, it is also one of the selectively vulnerable regions of cerebral ischemia.However, there are a few reports about neuronal damage induced by repetitive cerebral ischemia.OBJECTIVE: To investigate the pathological damage and mechanism of neurons induced by repetitive cerebral ischemia in thalamus.DESIGN: Randomized controlled experimental study.SETTING: Department of Neurology, General Hospital of Chengdu Military Area Command of Chinese PLA.MATERIALS: The experiment was carried out at the Animal Central Laboratory of the Third Military Medical University of Chinese PLA from March to December 1999. A total of 72 healthy male Wistar rats were randomly divided into sham operation group, single cerebral ischemic group,repetitive cerebral ischemic group, MK-801 treatment group and saline group.METHODS: Transient global cerebral ischemia models of rats were established with modified Pulsinelli-4 vessel occluing method for single 15-minute ischemia and repetitive three 5-minute ischemia at hourly intervals,followed by 5 hours, 2 days and 4 days of survival. Rats in sham operation group were not treated with burning vertebral artery and clipping common carotid artery. 45Ca autoradiography and light microscopy were used to determine the calcium accumulation and neuronal pathological changes of thalamus following repetitive cerebral ischemia as compared with single cerebral ischemia. The effects of MK-801, a N-methyl-D-aspartate (NMDA)receptor antagonist, were also examined.MAIN OUTCOME MEASURES: Distribution and degree of calcium accumulation and neuronal damage in the thalamus of rats in each group.RESULTS: Sham-operated rats revealed no abnormal calcium accumulation and neuronal damage in the thalamus. At 5 hours following ischemia,slightly abnormal calcium accumulation was found in the partial thalamus of the repeated ischemic group, and the neuronal damage was also relatively severer than that in the single ischemic group (0.98±0.19, 0.60±0.14, P＞ 0.05). At 2 days after ischemia, obviously abnormal calcium accumula tion and neuronal damage were shown in thalamus, and the degree of calcium accumulation and score of neuronal damage in repeated ischemic group were significantly severer than that in single ischemic group (1.62±0.31, 0.88±0.21, P ＜ 0.01). At 4 days, the thalamus calcium accumulation and neuronal damage were further increased, and also that in repeated ischemic group was significantly severer than that in single ischemic group (1.80±0.21, 1.02±0.23, P ＜ 0.01), especially marked calcium accumulation and cumulative damage were shown in the ventral thalamus. MK-801 significantly relieved the abnormal calcium accumulation and neuronal damage in the thalamus in repeated ischemic group, showing significant protection of thalamus neurons as compared with that in saline-treated group (0.20±0.12, 1.80±0.15, P ＜ 0.01).CONCLUSION: Repetitive non-lethal cerebral ischemia results in an intense cumulative damage in the ventral thalamus, and the excitatory amino acid and Ca2+ may play a major role in it.
