Glioblastoma multiforme （GBM） is the most common primary malignant brain tumor in adults, which accounts for approximately 50% of all gliomas. Its prognosis is particularly disappointing with a median life expectancy less than a year even when the patients are treated with the most aggressive regimens. Over the past 10 years, a number of trials have tried to establish whether adjuvant chemotherapy, as well as molecularly targeted therapy, provides GBM patients with clinically meaningful benefits.

Wet stability, penetration resistance （PR）, and tensile strength （TS） of paddy soils under a fertilization experiment for 22 years were determined to elucidate the function of soil organic matter in paddy soil stabilization. The treatments included no fertilization （CK）, normal chemical fertilization （NPK）, double the NPK application rates （2NPK）, and NPK mixed with organic manure （NPK＋OM）. Compared with CK, Fertilization increased soil organic carbon （SOC） and soil porosity. The results of soil aggregate fragmentation degree （SAFD） showed that fast wetting by water was the key fragmentation mechanism. Among the treatments, the NPK＋OM treatment had the largest size of water-stable aggregates and greatest normal mean weight diameter （NMWD）（P ≤ 0.05）, but the lowest PR and TS in both cultivated horizon （Ap） and plow pan. The CK and 2NPK treatments were measured with PR 〉 2.0 MPa and friability index 〈 0.20, respectively, in the Ap horizon, suggesting that the soils was mechanically unfavourable to root growth and tillage. In the plow pan, the fertilization treatments had greater TS and PR than in CK. TS and PR of the tested soil aggregates were negatively correlated to SOC content and soil porosity. This study suggested that chemical fertilization could cause deterioration of mechanical properties while application of organic manure could improve soil stability and mechanical properties.

为研究多漏风通道条件下采空区氧浓度分布规律,采用数值模拟对四种漏风情况下采空区自燃“三带”进行划分,并通过现场实测数据验证了模拟的准确性。结果表明:漏风导致氧化带向采空区深部移动,且漏风量随工作面向前推进逐渐增加,当采空区氧气浓度降低至8%时,进、回风侧到工作面距离由Ⅰ阶段的245m、140m,增大至Ⅳ阶段的420m、470m;2091工作面1、2号束管监测点与Ⅰ阶段数值模拟结果误差小于5%。该研究成果能够为类似漏风条件下采空区煤自燃的针对性防治提供理论基础及有力参考。

农业生产中过度使用无机磷肥引发了土壤板结等一系列问题,因此有必要寻找一种替代的可持续的磷肥来源。土壤有机磷主要以植酸的形式存在,植物不能直接吸收和利用。植酸水解释放植酸磷可提供一个生态友好型的解决方案。通过向土壤中添加来自Bacillus ***17的双功能域β-折叠桶植酸酶(phyHT),研究其在土壤中的稳定性,探究phyHT提高土壤有效磷含量、改善土壤理化性质以及促进植物生长的作用效果。结果显示,在湿润土壤中,土壤微生物对phyHT影响很小,phyHT可在较宽的温度(20~40℃)和pH值(6.0~9.0)范围内稳定存在12 h并发挥高效催化功能。外源性添加phyHT后:(1)土壤植酸含量减少了17.00%,有效磷含量增加了22.52%;(2)土壤pH下降,电导率上升,CaCO_(3)含量降低了3.55个百分点,土壤有机质、铵态氮和速效钾含量分别增加了10.54%、18.38%和27.49%;(3)小麦幼苗生长长度、干物质积累量以及芽、根部组织全磷含量均显著增加。因此,外源性添加phyHT能够促进土壤植酸水解,增加土壤有效磷含量,提高土壤磷素有效性,同时,在一定程度上改善土壤理化性质,促进植物生长。
