objective to compare four postoperative nasal packing materials.methods total 136 patients,80 cases with chronic sinus it is and under went endoscopic sinussurgery,were randomly packed using four different hae mostasis materials.in which,paraffin gauze group was 40 cases,rapid sorbalgon group 27 cases,merocel group 36 cases and gel knit group 31 cases.the packing materials wereemoved after left for 24 hours to 48 hours.the efficacy of nasal packing materials was asassessed interm of the levels of nasal pain or headache in the leaving period and nasal bleeding after removal of nasal packing.results the in cidence rate of nasal pain or headache respectively was 82.5% in paraffin gauze group,44.4% in merocel,11.1% in sorbalgon and 3.2% in gel knit.the significant statistical difference was observedbetween the four groups (χ2=70.21,p.01).the incidence rate of nasal bleeding after removed was 85%,11.1%,41.7% and 9.7% respectively.the statistical difference was also significant (χ2=54.28,p.01).conclusions the choosing of postoperative na sal packing after functional endoscopic sinus sur gey depends on various factors,gel knit has much advantages and can be used as routine packs after fess.

摘 要］目的：比较四种鼻腔填塞材料的疗效，指导临床选择合适的术后鼻内填塞物。方法：对134例慢性鼻窦炎分别采用凡士林纱条(40例)、藻酸钙纤维(sorbalgon，27例)、膨胀海绵(merocel，36例)和瑞纳凝胶快速止血材料(gel knit，31例)四种材料填塞鼻腔，24 h～48 h取出填塞物，根据填塞后鼻腔胀痛、头痛程度，取出填塞物后鼻腔出血程度等评价疗效。结果：凡士林纱条填塞组，82.5%有鼻腔胀痛或头痛；sorbalgon藻酸钙纤维组11.1%；merocel组44.4%；gel knit组3.2%，四组比较差异非常显著(χ2=70.21，p.01)。取出填塞物后鼻腔再出血分别为85%，11.1%，41.7%和9.7%，四组比较差异非常显著(χ2=54.28，p.01)。结论：鼻内镜手术时，应综合考虑诸方面因素合理选用术后填塞物。瑞纳优势较为全面，可作为鼻内镜手术的常规填塞材料。

Fish of sprouted broad bean group had higher FEAA, TFAA, hardness and gumminess than those of immersed broad bean group.

结果表明，配合饲料组、浸泡蚕豆组和发芽蚕豆组草鱼的增重率分别为83.08%、55.01%和62.82%，饵料系数分别为2.03、2.96和2.70，投饲浸泡蚕豆或发芽蚕豆显著降低了草鱼增重率(P.05)，增加了饲料系数(P.05)；与配合饲料组相比，浸泡蚕豆组和发芽蚕豆组草鱼肌肉粗脂肪含量和肌肉失水率显著降低(P.05)，胶原蛋白含量和肌纤维直径显著增加(P.05)；肌肉游离氨基酸中呈味氨基酸的含量显著下降(P.05)，而必需氨基酸含量显著增加(P.05)；肌肉的硬度和黏性也有了显著提高(P.05)。

On the basis of analyzing multicast schemes,such as MMT,AMFM and ATMM,this paper proposes an annular management strategy for multicast tree in MPLS network,aiming at that single management node brings bottleneck of the multicast tree and affects haleness of the MPLS network.

在分析MMT，AMFM和ATMM等组播方案的基础上，针对其单一管理节点容易成为骨干网上组播的瓶颈，影响MPLS骨干网上组播树的健壮性问题，提出一种环形管理组播树的策略，通过对该策略的仿真分析，表明该策略能有效地解决单个管理节点超载和组播聚合树的信息丢失等问题，提高骨干网络中组播聚合树的效率和健壮性。

Of them are treated with immunohistochemistry modus to detect Ki-67 expression; 4. Use SPSS13.0 for windows statistics software to chisquare inspection. Results: through detecting, heteroploid pecentage and Ki-67 positive expression of the patient who suffered breast cancer grouped in the zhengqi-weak-evil-strong type is the highest in the three typies(69.4%,94.4%).
