Objective Analysis of clinical features and treatment of nasal type NK/T cell lymphoma, to improve the understanding of this special type of lymphoma.Method The clinical data of 34 patients with nasal type NK/T cell lymphoma confirmed by pathology were retrospectively analyzed.Result In 31 cases, 26 cases were EB virus (EBV) infection positive, recent Treatment Effectiveness in the positive group was significantly lower than the negative group (38.46%vs. 87.50%;P<0.05) . Follow up showed until October 2015, 19 of 34 patients died. Among them, 17 cases died of disease relapse or progression, 2 cases died of other diseases. 15 patients survived (11 of them were disease-free) and the median overall survival time was 37 months. The 2 year overall survival was related to clinical stage, B symptoms, EBV infection (the P values were 0.017/0.001, 0.005, and 0.039 respectively).Conclusion EBV infection is associated with patient's treatment response in NK/T-Cell Lymphoma; and the prognosis is associated with clinical features such as clinical stage, B symptom, and EBV infection.

Objective: To confirm whether Biejiajian Pill has the action of promoting blood circulation to remove blood stasis, softening the hard lumps and dispelling the nodes. Methods: The blood stasis model, anti tumor model, the model of collagen and urinary hydroxyproline evacuating from fibrous liver of rat and the other pharmacological models were prepared to confirm the action of the pill. Results: (1) This pill has the absorption of erythrocyte and blood clot of itself. (2) After the pill being given to the rats with cirrhosis, the hepatitisfibrils decreased, the excretion of urinary hydroxyproline increased and the content of collagen of the therapeutics group was less than the control group. All of those suggested that this drug has the action of promoting the degradation of the collagen fiber and reabsorption of the hepatitis collagen. (3) This pill can apparently inhibit the proliferation of S 180 . Conclusion: The drug has the action of promoting blood circulation to remove blood stasis, softening the hard lumps and dispel the nodes.

Objective To explore the clinical therapeutic efficacy and value of endovascular embolization treatment for Hunt-Hess poor-grade intracranial aneurysms. Methods Eighty-seven patients with Hunt-Hess grade Ⅳ - Ⅴ intracranial aneurysrns were treated with endovascular embolization from May 2001 to February 2010,77 patients were grade Ⅳ and 10 patients were grade Ⅴ. Outcomes were assessed by using the Glasgow outcome scale (GOS). Results Follow-up time was from 3 months to 9 years. The therapeutic efficacy was as following according to GOS: 25 patients were grade Ⅰ , 5 patients were grade Ⅱ , 9 patients were grade Ⅲ , 12 patients were grade Ⅳ ,and 36 patients were grade Ⅴ. There were 55.17%(48/87) favorable outcome rate and 28.74% (25/87) mortality rate in all patients. There were 61.70%(29/47) favorable outcome rate and 25.53%(12/47) mortality rate in early stage treatment patients (diseased within 3 d), otherwise there were 47.50% (19/40) favorable outcome rate and 32.50%(13/40) mortality rate in medium and late stage treatment patients (diseased 3 d or later). There were no statistically significance in favorable outcome rate and mortality rate between them (P > 0.05). All the patients were embolized successfully ,technical complications occurred in 8 patients, 10 patients were found angiographic evidence of vasospasm. Conclusions Endovascular embolization is an effective method for treating Hunt-Hess poorgrade intracranial aneurysms. Early stage treatment is a feasible option because it can improve prognosis by reducing rebleeding and vasospasm.

The bioactive materials, such as biological glass, hydroxyl apatite, glass ceramics which contains the hydroxyl apatite and wollastonite, are possible to unify with the bone tissue together. However, many questions like whether the materials contact and unify directly with the bone, whether the speeds of unification have the differences, and whether materials themselves simultaneously have abilities to promote the bone formation are not clear and wait for the exposition. The researches have been made to observe the contact surface between biological material and bone, as well as the relationship among the apatite level and the bioactivity of materials through the transmission electron microscopy. In addition, in vivo hybridization has been used to discuss the mRNA expression and its influence in the cell around materials. The conclusion is that the bioactivity of glass ceramics is higher than that of hydroxyl apatite, with the easy unification with bone tissue.

Objective To validate near-infrared cerebral topography (NCT) as a practical toolin tracing the regional hemodynamic changes during normal ischemic stroke model of rat. Method Middle cerebral artery occlusion (MCAO) and photosensitizer induced intracranial infarction model of rat were established. The geometric shape and infarction area were measured by NCT, functional magnetic resonance imaging (fMRI), and TTC stained anatomical imaging techniques. Result In photosensitizer induced infarction model, the correlation between anatomical infarct area and NCT image area for infarct focus were r= 0.897 for 24 h group (P<0.05) and r=0.906 for 2 months group (P<0.01),respectively. The correlation between anatomical infarction area and NCT image area for infarct focus were r=0.820 for normothermia group (P<0.05) and r= 0.851 for hypothermia group (P<0.05), respectively. The correlation between fMRI and NCT image area for infarction focus were r= 0.874 for normothermia group (P<0.05) and r= 0.782 for hypothermia group (P<0.05),respectively. Conclusion Measurement with NCT for infarction focus matched well with fMRI and anatomic sample in rats. NCT technique might be a practical tool for short-term prediction of stroke and the rehabilitation after stroke in real time.
