利用控制初植密度和下层植物进行长期试验所得的资料,全面证实了我们的假设,即,林分生长与林冠的生长有直接关系,例如,生长量与冠幅成比例关系。无下层植物的黄松林分冠幅生长速度明显快于有下层植物的黄松林分。在叶面积指数非常低、特别是在林分的下层植物已被清除的情况下,森林生长率随着叶面积指数的增加而增加。然而,一旦叶面积指数超过2.0,森林生产率保持稳定,并且有下层植物和无下层植物的林分出现了差异。

AIM: To examine whether hepatitis C virus (HCV)-infected patients who carry hypercoagulable mutationssuffer from increased rates of liver fi brosis. METHODS: We analyzed DNA samples of 168 HCV patients for three common hypercoagulable gene mutations: prothrombin 20210 (PT20210), factor V Leiden (FV Leiden) and methylene tetrahydrofolate reductase (MTHFR). The patients were consecutively recruited as part of the prospective "Fibroscore Study" in France. The effect of the various mutations on the rate of fi-brosis was analyzed statistically and was correlated with epidemiological, clinical and biochemical data such as grade and stage of liver biopsies, patients' risk factors for liver cirrhosis, and timing of infection. RESULTS: Fifty two of the patients were categorized as "fast fi brosers" and 116 as "slow fi brosers"; 13% of the "fast fi brosers" carried the PT20210 mutation as compared with 5.5% of the "slow fi brosers", with an odds ratio of 4.76 (P = 0.033; 95% CI: 1.13-19.99) for "fast" liver fibrosis. Carriage of MTHFR or FV Leiden mutations was not associated with enhanced liver fi brosis. CONCLUSION: Carriage of the PT20210 mutation is related to an increased rate of liver fi brosis in HCV patients.

Cementum is the outer-, mineralized-tissue covering the tooth root and an essential part of the system of periodontal tissue that anchors the tooth to the bone. Periodontal disease results from the destructive behavior of the host elicited by an infectious biofilm adhering to the tooth root and left untreated, may lead to tooth loss. We describe a novel protocol for identifying peptide sequences from native proteins with the potential to repair damaged dental tissues by controlling hydroxyapatite biomineralization. Using amelogenin as a case study and a bioinformatics scoring matrix, we identified regions within amelogenin that are shared with a set of hydroxyapatite-binding peptides （HABPs） previously selected by phage display. One 22-amino acid long peptide regions referred to as amelogenin-derived peptide 5 （ADP5） was shown to facilitate cell-free formation of a cementum-like hydroxyapatite mineral layer on demineralized human root dentin that, in turn, supported attachment of periodontal ligament cells in vitro. Our findings have several implications in peptide-assisted mineral formation that mimic biomineralization. By further elaborating the mechanism for protein control over the biomineral formed, we afford new insights into the evolution of protein-mineral interactions. By exploiting small peptide domains of native proteins, our understanding of structure-function relationships of biomineralizing proteins can be extended and these peptides can be utilized to engineer mineral formation. Finally, the cementomimetic layer formed by ADP5 has the potential clinical application to repair diseased root surfaces so as to promote the regeneration of periodontal tissues and thereby reduce the morbiditv associated with tooth loss.

中国公共安全防控脆性浅探

中华灾害救援医学 2015年第4期3卷 181-185页

作者：张宏伟 Meir oren 彭心宇新疆维吾尔自治区石河子大学医学院第一附属医院普外科 832008 Hillel Yaffe Medical Center hadera38100

中国目前在公共安全的防控方面存在脆性一面,主要表现在防控体系建设不完善、日常管理缺陷、国家投入不足,以及公众意识薄弱等方面。笔者结合一些实际的公共安全案例,对比国内外的公共安全防控现状,对我国防控脆性进行了探讨。
