Neuromyelitis optica spectrum disease （NMOSD） refers to a group of related disease, in which potential pathogenesis is similar to neuromyelitis optica （NMO）, but clinical involvement does not exactly correspond to the diagnosis of NMO. Owing to varied clinical manifestations, it is apt to be misdiagnosed. We report a case of NMOSD with cervical spondylosis and discuss the experience of diagnosis.

Journal of Electronic Science and Technology 2013年第3期11卷 286-290页

---Double data rate synchronous dynamic random access memory （DDR3） has become one of the most mainstream applications in current server and computer systems. In order to quickly set up a system-level signal integrity （SI） simulation flow for the DDR3 interface, two system-level SI simulation methodologies, which are board-level S-parameter extraction in the frequency-domain and system-level simulation assumptions in the time domain, are introduced in this paper. By comparing the flow of Speed2000 and PowerSI/Hspice, PowerSI is chosen for the printed circuit board （PCB） board-level S-parameter extraction, while Tektronix oscilloscope （TDS7404） is used for the DDR3 waveform measurement. The lab measurement shows good agreement between simulation and measurement. The study shows that the combination of PowerSI and Hspice is recommended for quick system-level DDR3 SI simulation.

针对空-水量子密钥分发(Quantum Key Distribution,QKD),综合考虑海风影响、泡沫覆盖的不规则海面、空-水信道复杂多变性和量子偏振态多重散射过程,建立了非均匀空-水信道复合模型。据此完善了空-水QKD系统量子误码率理论模型,并采用偏振矢量蒙特卡罗算法模拟,详细分析了不同海洋环境下非均匀空-水信道光量子传输性能,及空-水QKD整体传输性能。结果表明:清澈海水条件下的非均匀空-水信道可实现水下百米量级的密钥分发,但风速和传输距离的增大都会导致光子退偏比增大,保真度减小,偏振误码率增加;同时风速和泡沫层厚度的增大也会造成空-水QKD系统量子误码率上升,密钥生成率和传输距离下降,且随信号波长的增加这两者也会增加,在波长为532 nm,信道由最佳(无风无泡沫)变至最差(暴风且泡沫层为6 cm)时,水下传输距离由120.8 m缩减至85 m,基本能保障水下航行器百米级的安全潜深,而采用拖拽浮标等措施又可进一步增加空-水QKD的安全距离。由此验证了泡沫覆盖不规则海面下非均匀空-水信道诱骗态QKD的可行性,对未来空-水一体量子通信链路的实现具有参考价值。

Hemangioma is a common benign vascular tumor,with an incidence of 2%-3% in the neonate and 10%in baby after 1 year.^1 The incidence of hemangiomas is approximately 22%-30% of preterm infants with birthweight less than 1000 g. The development of hemangioma is therefore supposed to be related to various intra- and extra-uterine factors.

本文在定义预期通货膨胀率函数后,将其代入标准总需求模型中得到一个扩展的总需求模型,此模型与标准总供给模型构成扩展的AD-AS模型。借鉴微观经济学中的超额需求函数,本文提出超额总需求函数。借助此函数,讨论了扩展的AD-AS模型均衡的静态稳定性。本文发现,内生变量——价格水平的变动通过预期通货膨胀的传递,使得总需求具有内生不确定性,并可能导致经济系统在预期通货膨胀很高时内生不稳定。这表明,政府要解决此问题,必须从改善经济系统的内部运行,从恢复价格对超额总需求的调节机制角度来考虑制定政策。

Molecular Mapping of a Stripe Rust Resistance Gene YrH9020a Transferred from Psathyrostachys huashanica Keng on Wheat Chromosome 6D

引用

Journal of Integrative Agriculture 2014年第12期13卷 2577-2583页

作者： LIU Ze-guang YAO Wei-yuan SHEN Xue-xue CHAO Kai-xiang FAN Yu LI Min-zhou WANG Bao-tong LI Qiang JING Jin-xue State Key Laboratory of Crop Stress Biology for Arid Areas College of Plant Protection Northwest A&F University

Stripe rust （yellow rust）, caused by Puccinia striiformis f. sp. tritici （Pst）, is one of the most devastating diseases of wheat throughout the world. H9020-1-6-8-3 is a translocation line originally developed from interspeciifc hybridization between wheat line 7182 and Psathyrostachys huashanica Keng and is resistant to most Pst races in China. To identify the resistance gene（s） in the translocation line, H9020-1-6-8-3 was crossed with susceptible cultivar Mingxian 169, and seedlings of the parents, F1, F2, F3, and BC1 generations were tested with prevalent Chinese Pst race CYR32 under controlled greenhouse conditions. The results indicated that there is a single dominant gene, temporarily designated as YrH9020a, conferring resistance to CYR32. The resistance gene was mapped by the F2 population from Mingxian 169/H9020-1-6-8-3. It was linked to six microsatellite markers, including Xbarc196, Xbarc202, Xbarc96, Xgpw4372, Xbarc21, and Xgdm141, lfanked by Xbarc96 and Xbarc202 with at 4.5 and 8.3 cM, respectively. Based on the chromosomal locations of these markers and the test of Chinese Spring （CS） nullitetrasomic and ditelosomic lines, the gene was assigned to chromosome 6D. According to the origin and the chromosomal location, YrH9020a might be a new resistance gene to stripe rust. The lfanking markers linked to YrH9020a could be useful for marker-assisted selection in breeding programs.

OBJECTIVE: To investigate blood pressure rhythm(BPR)in Yin deficiency syndrome of hypertension(YDSH)patients and develop a random forest model for predicting ***: Our study was consistent with technical processes and specification for developing guidelines of Evidence-based Chinese medicine clinical practice(T/CACM 1032-2017). We enrolled 234 patients who had been diagnosed with primary hypertension without antihypertensive medications prior to the enrollment. All participants were divided into Yin deficiency group(YX, n = 74) and non-Yin deficiency group(NYX, n = 160).Participants were professionally grouped by three experienced chief Traditional Chinese Medicine(TCM)physicians according to four examinations(i.e.,inspection, listening and smelling, inquiry and palpation).We collected data on 24 h ambulatory blood pressure monitoring(ABPM) and YDSH rating scale. We divided 24 h of a day into 12 two-hour periods [Chen-Shi(7:00-9:00), Si-Shi(9:00-11:00), Wu-Shi(11:00-13:00), Wei-Shi(13:00-15:00), Shen-Shi(15:00-17:00), You-Shi(17:00-19:00), Xu-Shi(19:00-21:00), Hai-Shi(21:00-23:00), ZiShi(23:00-1:00), Chou-Shi(1:00-3:00), Yin-Shi(3:00-5:00), Mao-Shi(5:00-7:00)] according to the theory of “midnight-midday ebb flow”. We used random forest to build the diagnostic model of YDSH, with whether it was Yin deficiency syndrome as the outcome. RESULTS: Compared with NYX group, YX group had more female participants with older age, lower waist circumference, body mass index(BMI), diastolic blood pressure(DBP), and smoking and drinking rate(all P < 0.05). The YDSH rating scores of YX group [28.5(21.0-36.0)] were significantly higher than NYX group [13.0(8.0-22.0)](P < 0.001), and the typical symptoms of YX group included vexing heat in the chest, palms and soles, dizziness, dry eyes, string-like and fine pulse, soreness and weakness of lumbus and knees, palpitations, reddened cheeks, and tinnitus(all P < 0.05). The ratio of non-dipper hypertension in YX group was higher t
