OBJECTIVE: To analyze the safety and efficacy of intracranial arteriovenous malformation（AVM） embolized with the liquid embolic agent Glubran 2 [N-butyl-2-cyanoacrylate（NBCA） + Metacryloxysulfolane（MS）]. Material and methods: From January 2011 to December 2017, 414 consecutive cases of intracranial AVMs embolized with Glubran2 in the same vascular group at the Department of Neurosurgery,Zhujiang Hospital,Southern Medical University were enrolled retrospectively. The general details, and information on postoperative embolization effect and complications were collected. There were 324 cases of Spetzler-Martin, Grades I to Ⅲ, 90 cases of Grades Ⅳ to Ⅴ. 319 cases were embolization-only and 95 cases underwent stereotactic radiotherapy（SRS） after embolization. The 414 cases were divided into occlusion group and incomplete occlusion group according to the outcome of DSA after operation. 319 cases were enrolled in the occlusion group. 95 cases were enrolled in the incomplete occlusion group. Univariate and multivariate logistic analysis was performed for complete occlusion. Results: The complete occlusion rate of the 414 AVM patients was 21.74%（90/414）. The complete occlusion rate of embolization-only AVM was 15.36%（49/319）. AVM occlusion rate of embolization combined with SRS was 43.16%（41/95）. The complication incidence of the NBCA+MS liquid embolic embolized patients was 8.94%（37/414）, morbidity（permanent functional disorder as the criterion） was 1.93%（8/414）, mortality was 0. Multivariate logistic regression analysis showed that AVM with SM grade ≦Ⅱ could achieve a higher complete occlusion rate（OR=0.277, 95%CI: 0.170-0.451, P＜0.001）Conclusion: the liquid NBCA+MS is safe and effective as an intracranial AVM embolization agent. Its embolization combined with SRS could be helpful to achieve higher obliteration rate of intracranial AVM.

The feedstocks for biodiesel production are predominantly from edible oils and the high cost of the feedstocks prevents its large scale *** this study,we evaluated the oil extracted from Boettcherisca peregrine larvae(BPL) grown on solid organic wastes for biodiesel *** oil contents detected in the BPL converted from swine manure,fermentation residue and the degreased food waste, were 21.7%,19.5%and 31.1%,*** acid value of the oil is 19.02 mg KOH/g requiring a two-step transesteriflcation *** optimized process of 12:1 methanol/oil(mol/mol) with 1.5%H2S04 reacted at 70℃for 120 min resulted in a 90.8%conversion rate of free fatty acid(FFA) by esterification,and a 92.3% conversion rate of triglycerides into esters by alkaline *** of the BPL oil-based biodiesel are within the specifications of ASTM D6751,suggesting that the solid organic waste-grown BPL could be a feasible non-food feedstock for biodiesel production.

For the supersonic air vehicles,the base drag could be amount to 30%～40%of the total *** in the base drag is highly desirable to achieve the overall drag reduction and longer flight *** base drag reduction control methods generally contain two typical forms,*** active and passive *** control methods can reduce the base drag by increasing the base pressure,even achieve thrust,but they need additional devices and complex control *** modifications of base geometry can be considered as effectively passive drag reduction methods which do not alter base structures and induce little additional skin friction drag.

目的：确立患者腰骶神经根可以耐受的单次最大拉力,制定神经根耐受牵拉的安全阈值,是自行设计神经根安全拉钩的最终意义。方法：于2004-10/2006-12选择南通大学第二附属医院脊柱外科应用自制神经根安全拉钩完成腰椎后路椎体间融合手术患者共56例,其中L4～532例,L5/S124例。实验经医院伦理委员会批准,患者均知情同意。术中应用Keypoint型诱发肌电仪进行节段性皮神经刺激体感诱发电位的监测,同时记录牵拉神经根的力和牵拉时间。结果：术中出血50～320mL,平均约120mL;手术时间90～180min,平均130min;术中12例患者出现潜伏期延长、波幅下降,此时神经根拉力为（4.10±0.25）N。术后有11例患者出现下肢麻木,随访结束时仍有8例下肢残留麻木。其余44例患者术中监护波形稳定,术后有16例患者出现下肢麻木,随访结束时仍有5例下肢残留麻木。结论：应用自制神经根安全拉钩可以最大程度牵拉神经根,更精确的计算需暴露的手术野,降低神经根牵拉性损伤的概率,提高治疗质量。

THE spatial distribution pattern of an element content is controlled by various geochemical pro-cesses. Studies on the spatial pattern are beneficial to further analysis on the factors. As a re-sult, our knowledge about the geochemical processes is enriched. At the same time, describingthe spatial patterns quantitatively with some indices is one way from qualitative to quantitativeanalysis.

NITRIC oxide (NO) is the important cell messenger molecule that regulates the central ner-vous, cardiovascular, endocrine and immunity systems. The study of NO not only canexplain many physiological phenomena, but also can provide new ways to prevent and treat alot of diseases. However, at present, most of the methods for assaying NO produced by or-ganism have some defects, for example, low sensitivity, no specificity, no convenience.

IN photodynamic therapy, the damage of protein results from the photooxidation of one ormore of only five amino acid residues (tryptophanyl, tyrosyl, histidyl, methionyl and cys-teinyl). These five amino acids are also readily photooxidized in their monomeric states. How-ever, the reaction kinetics and mechanisms of free amino acids and bound amino acid residuesin proteins are somewhat different. For example, Tassin found that the incorporation of tryp-tophan into a peptide linkage dramatically altered its susceptibility to photooxidation as well
