AIM: To evaluate the prognostic value of the combined model for end-stage liver disease (MELD) and blood lipid level in patients with decompensated cirrhosis. METHODS: A total of 198 patients with decompensated cirrhosis were enrolled into the study. The values of triglyceride (TG), cholesterol (TC), high density lipoproteins (HDL) and low density lipoprotein (LDL) of each patient on the fi rst day of admission were retrieved from the medical records, and MELD was calculated. All the patients were followed up for 1 year. The relationship between the change of blood lipid level and the value of MELD score was studied by analysis of variance. The prognostic factors were screened by multivariate Cox proportional hazard model. Draw Kaplan-Meier survival curves were drawn. RESULTS: Forty-f ive patients died within 3 mo and 83 patients died within 1 year. The levels of TG, TC, HDL and LDL of the death group were all lower than those of the survivors. The serum TG, TC, HDL and LDL levels were lowered with the increase of the MELD score. Multivariate Cox proportional hazard model showed that MELD ≥18 and TC ≤2.8 mmol/L were independent risk factors for prognosis of decompensated cirrhosis. Survival analysis showed that MELD ≥18 combined with TC ≤ 2.8 mmol/L can clearly discriminate between the patients who would survive and die in 1 year. CONCLUSION: MELD ≥18 and TC ≤2.8 mmol/L are two important indexes to predict the prognosis of patients with decompensated cirrhosis. Their combination can effectively predict the long-term prognosis of patients with decompensated cirrhosis.

To solve the problem that soybean has narrow genetic base, we constructed a series of male sterile recurrent selection populations, and studied the effects of quality improvement and practical value. An LD-base population, which fits to our ecology type was constructed by 6 years＇ gene enrichment through the introduction of new genes from 23 local varieties and recurrent selection. The LD-base populations were then improved by making crosses with high protein and high oil genotypes. As a result we obtained a high protein sub-population （db） and a high oil sub-population （gy）, For the db sub-population, the protein content is 1.18% higher than the base population, 22.38% of the individuals contain 45% or more of protein, which is 10.99% higher than the base population. For the gy sub-population, oil content is 0.24% higher than the base population. Individuals with oil content of 20% or more are 11.05% higher than the base population. The quantitative characters such as flowering date, mature date, pod habit, and hilum color, etc., all showed wide range of separation, and the segregation ratio approached balance. The c.v. of branch number of ms1 recurrent population （72.8%） is higher than general cross-population （57.3%）, and the c.v. of 100 seed weight of ms1 （18.1%） is higher than general cross population （16.5%）, the coefficient of variation of plant height, pods per plant, and seeds per pod were not significantly different. It was demonstrated in this paper that the quality character of ms 1 male sterile recurrent selection population was improved by adding new genes. And the segregation of other characters widened, making the populations suitable for the objective of soybean breeding. In this paper, we also discussed the breeding method, key technology, and selection effect of soybean ms 1 population.

针对现有社交网络用户推荐方案中大规模网络个体相似性计算复杂度高以及个体节点无差异对待的问题,本文提出一种基于二部图和节点角色划分的推荐方案.首先,通过划分重叠群体简化原生社交网络结构,并进一步构建群体-个体二部图模型;其次,通过群体-个体二部图所反映的拓扑特征,结合节点自身属性特征,对个体进行角色划分,提出一种基于群体-个体二部图的角色划分模型;最后,针对大规模网络中计算个体相似性复杂度高的问题,构建基于角色差异下的个体-个体二部图模型,实现层次化、个性化的推荐.实验表明,该方案适用于对社交网络中兴趣广泛度存在差异的个体间进行好友推荐,并在较小规模的二部图上生成目标个体推荐列表,降低了计算个体相似性的复杂度.

《土耳其民法典》与《埃及民法典》是中东伊斯兰国家法律现代化进程中的两部代表性民法典。虽然近现代以来两国都移植借鉴了西方民法,但是两国的民法典却存在明显差异,相应地形成了中东地区民法典的两种模式。《土耳其民法典》坚持全盘西化,《埃及民法典》则试图在传统与现代间进行调和。由于伊斯兰法律文化与西方法律文化间难以弥合的差异,中东伊斯兰国家学习、借鉴西方的法律现代化之路注定不平坦。

对大量有害的URL进行过滤,是目前网络安全应用系统中所亟需的关键技术.使用经典的串匹配算法检测庞大的URL规则集,需要消耗大量的计算资源和存储资源,性能十分低下.该文设计了一种适合于大规模URL过滤的多模式串匹配算法——SOGOPT.该算法在经典的SOG算法基础上,针对URL规则的特点,提出了最优窗口选择、模式串分组规约这两种优化技术,大幅度提高了SOG算法的匹配速度,在大规模URL规则集上效果尤其显著.该文设计的算法非常适合于大规模(100万级)URL实时在线匹配的应用环境.
