BACKGROUND: Altered expression of the BCL-2 family member MCL-1 has been linked to the progression and outcome of various malignancies. However, MCL-1 expression pattern in acute myeloid leukemia（AML） and its impact on prognosis remain poorly defined. METHODS: Real-time quantitative PCR was carried out to detect the pattern of MCL-1 expression in AML patients. RESULTS: MCL-1 expression was significantly up-regulated in AML compared with controls（P=0.042）. High MCL-1 expressed patients had a higher incidence of NPM1 mutation（P=0.030）. Moreover, MCL-1 overexpression correlated with lower complete remission（CR） rate and shorter overall survival（os） time. Meanwhile, Cox regression analyses revealed that overexpression of MCL-1 acted as an independent risk factor not only in non-APL patients but also in CN-AML patients（P=0.011 and P=0.045, respectively）. Furthermore, gene expression profiling（GEP） data also confirmed the adverse prognostic impact of MCL-1 high-expression in CN-AML patients. In follow-up patients, MCL-1 expression level decreased after CR compared with newly diagnosis time（P=0.020） and increased after relapse（P=0.004）. CONCLUSION: Our findings suggest that MCL-1 overexpression predicts poor prognosis and can be used for disease monitoring.

The commutators of oscillatory singular integral operators with homogeneous kernel $\frac{{\Omega (x)}}{{\left| x \right|^n }}$ are studied, where Ω is homogeneous of degree zero, has mean value zero on the unit sphere. It is proved that Ω∈L (logL)K+1(Sn-1) is a sufficient condition under which the k-th order commutator is bounded on L2(Rn).

在防雨池栽条件下,研究了施氮量和花后土壤含水量对优质强筋小麦产量和品质的影响。结果表明,在同一施氮量条件下,表现为花后土壤含水量过高（80%～90%）或过低（40%～50%）导致穗粒数减少,千粒重降低,最终使产量降低。在同一土壤含水量下,表现为增加施氮量有利于提高穗数,但过多（300kg/hm^2）或过少（150kg/hm^2）施氮均不利于穗粒数和千粒重的提高,而导致减产。在同一土壤含水量下,总蛋白质、醇溶蛋白、麦谷蛋白含量及谷/醇比随着施氮量的增加而增加。在同一施氮量条件下,总蛋白质及各组分均随着土壤含水量的增加而降低,同时谷/醇比也降低。在同一施氮量下,花后土壤含水量过高（80%～90%）或过低（40%～50%）均不利于淀粉及其组分含量的提高。在同一土壤含水量下,过高（300kg/hm^2）或过低（150kg/hm^2）施用氮肥均不利于淀粉及其组分含量的提高。只有保持适宜的花后土壤含水量和施适宜的氮肥才有利于支/直比的提高。适量增施氮肥或花后土壤含水量适宜可提高小麦的加工品质。这说明在小麦生产中可以通过施用氮肥和控制花后土壤水分含量技术,调控小麦品质和产量的形成,从而实现优质高产。

Existing interference protection systems lack automatic evaluation methods to provide scientific, objective and accurate assessment results. To address this issue, this paper develops a layout scheme by geometrically modeling the actual scene, so that the hand-held full-band spectrum analyzer would be able to collect signal field strength values for indoor complex scenes. An improved prediction algorithm based on the K-nearest neighbor non-parametric kernel regression was proposed to predict the signal field strengths for the whole plane before and after being shield. Then the highest accuracy set of data could be picked out by comparison. The experimental results show that the improved prediction algorithm based on the K-nearest neighbor non-parametric kernel regression can scientifically and objectively predict the indoor complex scenes’ signal strength and evaluate the interference protection with high accuracy.
