Intracranial aneurysm often result from congenital defects of regional cerebral artery wall and increased endovascular pressure.Its occurrence and development are associated with several risk factors including genetics,smoking,hypertension,cerebral atherosclerosis and vasculitis.With the application of gene chip technology for the past few years,the research of pathogenic genes associated with intracranial aneurysms was further deepened,and some susceptibility genes closely associated with the occurrence of intracranial aneurysms have been found,and this suggests that intracranial aneurysm may be a polygenic disease caused by the combined action of multiple genes.

Objective To study the characteristics of vestibular autorotation test (VAT) in patients with the posterior circulation transient ischemic attacks(PCTIA) ,further reveal the pathogenesis vestibular function damage because of PCTIA .Methods VAT was performed on 41 patients with posterior circulation transient ischemic at‐tacks(PCTIA group) and 30 healthy controls(control group) .Parameters analyzed included gains ,phases and a‐symmetry of VAT .The positive result of the test could be defined if any of the paramaeters was abnormal .Results In the PCTIA group and control group ,gains were enhanced without being reduced as showed in 25 (62 .5% ,25/40) cases and 5(16 .7% ) ,respectively (χ2 =7 .09 ,P<0 .01) ,gains were enhanced with reduced as showed in 10(25% ) cases and 0(0% ) ,respectively (χ2 =8 .78 ,P<0 .01) .Conclusion The results of VAT in patients with the PCTIA can show gains enhanced with reduced in different frequency .VAT can provide valuable reference on positioning as‐sessment of vestibular system damage in patients with PCTIA .

Objective To explore the effects of high intensity focused ultrasound (HIFU) on cell multiplication and apoptosis at exposure coverage and marginal zone and the expression of vascular endothelial growth factor (VEGF) and proliferating cell nuclear antigen and apoptosis of subcutaneous neurogliocytoma in nude mice. Methods Eighteen nude mice bearing subcutaneous human neurogliocytoma were consecutively ablated in 20s by an extracorporeal HIFU with 9.7MHz transducer (the focal length of 4.5mm and focal intensity 2500W/cm2). The 18 nude mice were randomly di?vided into 7 d group,14 d group and 30 d group according to sacrifice date. Immunohistochemical method, TdT-mediat?ed dUTP nick end labeling method were used to examine the expression of vascular endothelial growth factor and prolifer?ating cell nuclear antigen and apoptosis at exposure coverage, marginal zone and normal zone, respectively. Results The expression of VEGF and proliferating cell nuclear antigen were evident at exposure coverage, marginal zone and normal zone in 7, 14 and 30 days after ablation. The expression of proliferating cell nuclear antigen and apoptosis were absent at exposure coverage in 7,14 and 30 days after ablation. The percentage of VEGF expression was lower in marginal zone than in normal zone (23.79%± 3.11% vs. 46.16%± 2.43%) in 7 d after ablation (F=110.03,P<0.05). The percentage of VEGF expression was also lower (10.94%±3.95%) in exposure coverage than in normal zone (46.16%±2.43%) in 7 d af?ter ablation (F=272.80,P<0.05). The percentage of VEGF expression was lower in marginal zone than in normal zone (17.17%±2.89%vs. 43.47%±3.77%) in 14 d after ablation (F=152.05,P<0.05). The percentage of VEGF expression was lower in marginal zone than in normal zone (9.27%± 2.08%vs. 44.58%± 3.34%) in 30 d after ablation (F=274.1,P<0.05 2). The proliferating cell nuclear antigen labeling index(PCNA LI) was lower in marginal zone than in normal zone ((33.04%±4.31%vs. 65.15%±3.85%) in 7 d after ablation (F=242.46, P<0.05). The PCNA LI was lower in marginal zone than in normal zone (21.05%± 1.96%vs. 62.99%± 3.34%) in 14 d after ablation (F=413.52, P<0.05). The PCNA LI was lower in marginal zone than in normal zone (6.36%± 0.51% vs. 62.07%± 18.07%) in 30 d after ablation, (F=729.59, P<0.05) .The apoptotic index (AI) was higher in marginal zone than in normal zone (26.10%±4.54%vs. 1.43%±0.35%) in 7 d after ablation, (F=216.22, P<0.05). The apoptotic index(AI) was higher in marginal zone than in normal zone (65.70%± 1.14% vs. 1.82%± 0.31%) in 14d after ablation (F=1448.64, P<0.05). The apoptotic index (AI) was higher in marginal zone than in normal zone (82.02%± 3.98% vs. 2.52%± 0.29%) in 30d after ablation (F=2244.33, P<0.05). Conclusion The present study demonstrates that an extracorporeal HIFU with 9.7MHz transducer (the focal length of 4.5mm and fo?cal intensity 2500W/cm2) can completely ablate neurogliocytoma at exposure coverage and inhibit the proliferation of neurogliocytoma at marginal zone. Thus, HIFU may be a new and selective treatment for neurogliocytoma.

Purpose The glucosamine and chondroitin compound tablets were prepared. The anti-inflammatory and analgesic effects of glucosamine and chondrotin compound tablets were investigated. Methods The proportion of glucosamine and chondroitin was 5:4 to prepare compound tablets. The anti-inflammatory effect was investigated with carrageen-induced rats paw edema and cotton granuloma in rats. The analgesic effect was investigated using the pain models of mice which were induced by 0.6% acetic acid. Results Compared with control group the degree of paw edema in the low, middle and high dose group was decreased ( P < 0.05). Fourtreatment groups compared with control group respectively at the weight of granuloma were also markedly reduced ( P < 0.05) and the writhing number of mice induced by acetic acid was decreased ( P < 0.05 ) . Conclusion glucosamine and chondroitin compound tablets have anti-inflammatory effect and analgesic effect on models induced by acetic acid.
