Objective： To evaluate the effects of polymorphisms in TLR7 and TLRS（as potential candidate genes） on asthma risk and asthma-related phenotypes. Methods： We consecutively recruited 318 unrelated adult asthmatic patients and 352 healthy volunteers from the same area of southeast China. Genotyping of each selected SNP was performed using multiplex PCR in conjunction with tagged array single base extension technology. We conducted case-control and case-only association studies between the selected SNPs in TLR7 and TLR8 and asthma or asthma-related phenotypes. Results： The T allele of rs5935436 SNP in TLR7 was protective from developing asthma in males （adjusted ORs = 0.126, 95% CIs = 0.016-0.995）. The CT/TT genotype of rs5935436 was less frequent in female asthmatics with allergic rhinitis （adjusted ORs = 0.18, 95% CIs = 0.04-0.90）. The homozygote AA of rs3761623 and GG of rs3764880 were positively associated with lower FEV1% and asthma severity in female asthmatics. These results were confirmed by haplotype analysis. Conclusion：TLR7 and TLR8 polymorphisms may play an important role in the pathogenesis of asthma that is gender-dependent. This could be clinically useful, both for identifying patients at risk of asthma and for preventing its occurrence.

结合结构振动方程和非线性流体振子方程得到耦合模型并进一步得到能量捕获效率计算公式,根据Stappenbelt的实验设置对双自由度的圆柱体流致振动进行数值模拟,分析不同质量比在低阻尼比条件下的振动响应,发现随质量比增加,顺流向和横向的振幅均减小。对无量纲振幅比的分析表明,阻尼比大于0.1时,不同质量比下的顺流向振动比横向振动更小,可忽略。能量捕获效率分析结果指出低质量比条件具有较高的捕获效率,对比不同阻尼比条件发现,在阻尼比为0.05且质量比最低时出现最高的捕获效率38%。

Atomic-layered hexagonal boron nitride(hBN)is expected to be the best two-dimensional(2D)anti-oxidation layer on metals for its incomparable impermeability,insulativity,and stability,as well as the progressive bottom-up growth techniques to ensure fast coating on metal surface in large ***,its real anti-oxidation ability in practice is found to be unsatisfactory and nonuniform,and the main obstacle to achieving ideal anti-oxidation performance lies in unclear anti-oxidation behavior at special interface between 2D hBN and three-dimensional(3D)***,system of monolayer hBN grown on copper(Cu)foils with various lattice orientations was grown to investigate the anti-oxidation behavior of different interlayer *** using structural characterizations together with analysis of topography,we surprisingly found that stronger interlayer coupling led to worse anti-oxidation performance owing to fast diffusion of O2 through higher hBN corrugations generated at the commensurate hBN/Cu(111)*** view of this,we developed the approach of cyclic reannealing that can effectively flatten corrugations and steps,and therefore improve the anti-oxidation performance to a great *** work provides a more indepth understanding of anti-oxidation behavior of 2D materials grown on 3D metals,and a practical method to pave the way for its large-scale applications in future.

沟灌地表水流与溶质动力学耦合模型可为沟灌施肥系统的优化设计与管理提供有力工具,然而已有相关模型无法考虑沟底相对高程随机分布,且存在溶质对流和弥散过程的分裂误差以及由此带来的不稳定性等缺陷。为此,该文采用守恒型全水动力学方程和对流-弥散方程描述沟灌地表水流与溶质运动过程,借助双时间步法和有限体积法,并在地表水位相对高程梯度向量离散式中引入额外项,以精确模拟考虑沟底相对高程随机分布下地表水流推进与消退过程,实现了无条件稳定性下对沟灌地表水流与溶质运动所有物理过程的动力学耦合模拟。借助全程、前半程和后半程施肥时机下9个典型沟灌施肥试验实测数据,验证了模型的模拟效果。结果表明,模型能以优良的拟合度模拟出考虑地表相对高程随机分布下沟灌地表水流推进与消退过程,以及地表溶质浓度演变过程,且水量与溶质量的质量守恒误差小于0.1%,有效克服了已有模型的缺陷,为沟灌施肥系统的优化设计与管理提供了优良的数值分析工具。

为准确预测翼型低雷诺数条件下出现的层流分离流动现象,发展了基于结构化拼接网格的大涡模拟方法。控制方程为Favre滤波Naver-Stokes方程,并选用多种亚格子模型。空间离散采用AUSM格式以及高阶WENO格式,时间推进采用显式方法和隐式方法。以SD7003翼型在雷诺数60000及4°迎角下的层流分离流动为研究对象,对比分析了数值格式、亚格子模型、网格尺度对流场预测结果的影响。数值结果表明:划分的计算网格能够有效解析小尺度流动结构,基于隐式亚格子模型、采用AUSM格式和双时间步推进的大涡模拟方法能够准确预测流动分离、转捩、再附等复杂流动现象,计算得到的平均压强系数与雷诺应力分布与文献数据吻合较好。与转捩模式计算结果对比进一步表明:发展的大涡模拟方法能够准确预测翼型低雷诺数层流分离流动非定常演化过程,为下一步的研究工作建立了有效的数值模拟手段。

OBJECTIVE:To explore factors influencing the curative effect of scraping therapies (at acupoints or along channels) and to determine the relationship of scraping site and strength to curative effect. METHODS: Two hundred and ten patients with lumbar muscle strain were divided into five groups with 42 patients *** "scraping therapy at acupoint until appearance of skin eruptions" and "scraping therapy along channel until appearance of skin eruptions" groups were treated with a 4-daycourse. The "scraping therapy at acupoint without appearance of skin eruptions", "scraping therapy along channel without appearance of skin eruptions", and acupuncture groups were treated with a 2-day *** five groups were treated with seven courses. The visual analog scale (VAS), oswestry disability index (ODI), and lumbago scores were recorded in the five groups before treatment, after each treatment, and in follow-up visits one month and three months after treatment. RESULTS: VAS, ODI, and lumbago scores after treatment improved in the five groups (P<0.01). There was a statistical difference (P<0.01) in the change of VAS scores by appearance of skin eruptions and scraping site. CONCLUSION: Scraping therapy can effectively alleviate lumbago symptoms. The appearance of skin eruptions and scraping therapy along channels can enhance the curative effect of scraping therapy.
