Chinese Medical Journal 2011年第6期124卷 892-896页

作者： HAO Guo-zhen JIANG Yun-fa FAN Wei-ze LI shi-qiang Department of Cardiology Second Hospital of Hebei Medical University Shijiazhuang Hebei 050000 China

Background Diabetic patients undergoing percutaneous coronary intervention （PCI） have a higher incidence of contrast-induced nephropathy （CIN） than nondiabetic patients, and no pharmacological approach has been demonstrated to offer consistent protection. Therefore, identifying individuals who are at increased risk becomes essential. This study was designed to assess the predictive role of the ratio of contrast medium volume to estimated glomerular filtration rate （CMV/eGFR） in diabetic patients undergoing elective PCI who developed *** We retrospectively investigated clinical factors associated with the development of CIN in 114 diabetic patients who had undergone elective PCI. The risk factors for CIN included age, gender, body mass index （BMI）, left ventricular ejection fraction （LVEF）, hemoglobin （Hb）, fasting plasma glucose （FPG）, hemoglobin A1c （HbA1c）, volume of contrast medium, basic levels of serum creatinine （Scr）, the number of treated vessels and the number of stents *** conducted a stepwise regression analysis to evaluate the predictive role of these risk factors in the incidence of *** The incidence of CIN was 18.4% （21/114）. There were no significant differences in age, gender, BMI, LVEF, Hb,FPG, HbA1c, and incidence of hypertension and number of acute myocardial infarction （AMI） in patients between the CIN （n=21） and the non-CIN （n=93） groups. However, the eGFR was significantly lower （（72.0±12.5） ml·min-1·1.73 m-2 vs.（82.0±16.5）ml·min-1·1.7m-2, P=0.010）, and the basic serum creatinine level （（1.07±0.12） mg/dl vs.（0.97±0.19） mg/dlP=0.014） was significantly higher in the CIN group. In addition, the volume of contrast medium was significantly larger （（253±75）ml vs. （211±71）ml, P=0.017） and the CMV/eGFR ratio was significantly greater （3.64±1.26 vs.2.70±1.11, P=0.001） in the CIN group. Stepwise regression analysis showed that the CMV/eGFR ratio was a significant independent predictor for the development of CIN （P=0.001）. At a cut-off

Survey of design and security evaluation of authenticated encryption algorithms in the CAESAR competition

Frontiers of Information Technology & Electronic Engineering 2018年第12期19卷 1475-1499页

作者： Fan ZHANG Zi-yuan LIANG Bo-lin YANG Xin-jie ZHAO shi-ze GUO Kui REN College of Information Science and Electronic Engineering Zhejiang University Institute of Cyberspace Research Zhejiang University State Key Laboratory of Cryptology Alibaba-Zhejiang University Joint Institute of Frontier Technologies Institute of North Electronic Equipment

The Competition for Authenticated Encryption: Security, Applicability, and Robustness(CAESAR)supported by the National Institute of Standards and Technology(NIST) is an ongoing project calling for submissions of authenticated encryption(AE) schemes. The competition itself aims at enhancing both the design of AE schemes and related analysis. The design goal is to pursue new AE schemes that are more secure than advanced encryption standard with Galois/counter mode(AES-GCM) and can simultaneously achieve three design aspects: security,applicability, and robustness. The competition has a total of three rounds and the last round is approaching the end in 2018. In this survey paper, we first introduce the requirements of the proposed design and the progress of candidate screening in the CAESAR competition. Second, the candidate AE schemes in the final round are classified according to their design structures and encryption modes. Third, comprehensive performance and security evaluations are conducted on these candidates. Finally, the research trends of design and analysis of AE for the future are discussed.

Cloning and sequence analysis of cold inducible RNA-binding protein cDNA from testis tissue in BALB/C mice

Journal of Agricultural Science and Technology 2008年第10期2卷 31-35页

作者： LI shi-ze JIN Fu-hou PANG Yah College of Animal Science and Technology Heilong/iang August First Land Reclamation University Daqing 163319 China Heilongjiang Qiang＇er Biochemical Development Co. Ltd Harbin 150090 China

The effect of cold stress on the gene expression of cold-inducible RNA-binding protein （CIRP） in the intravital animals has not been reported till now. Compared with their organism cells, there were much more complicated regulatory mechanisms for cold stress response in the organisms. The BALB/C mice with cold treatment were used as experimental animals for this study. The cDNA of CIRP was firstly cloned from the testis tissues of the BALB/C mice treated by cold stress The results indicated that CIRP in the organisms could be induced at low temperature and may protect the organisms from the cold damage. The amino acid sequence deduced via cDNA clone was 100%, 99.4%, 95.5%, 67.4%, 76.9%, 79.1% and 58.4% identical with that of CIRP in mice, rats, human, bullfrog, Xenopus and axolotl cells, respectively. These results showed that the CIRP was highly conserved in the evolution process and may be involved in various physiological functions. Therefore, this study will establish a systematic model for experiments and provide a new foundation for exploring the molecular mechanisms of human and other animals under cold stress.

为了高效、准确地估计相干信号的波达方向(DOA),提出了一种基于特征空间多重信号分类(MUSIC)算法的空间平滑估计方法。首先对相干信号进行空间平滑处理,然后对其应用特征空间MUSIC算法进行DOA的精确估计,使其最大限度地利用信号子空间和噪声子空间的信息。本文方法并不影响非相关信号存在时DOA的估计,且还可以对信号源功率进行有效的估计,以提高对小能量信号的成功估计概率。与传统空间平滑算法及修正MUSIC算法相比,本文方法具有更低的信噪比门限和更高的估计精度及分辨力。最后的仿真实验验证了本文方法的有效性和鲁棒性。

提出了基于BP神经网络的畸变校正方法,实现了在不确知畸变数学模型情况下的高精度校正。应用平行光管法测得900组光点坐标数据作为BP神经网络的训练样本,通过训练得到一个隐含层有6个节点的3层BP神经网络模型,然后使用77组数据检测了该神经网络的校正效果,并与使用相同检测数据的双线性插值方法进行了比较。实验表明,神经网络较插值方法精度高,误差数据分布的规律性好,而且与插值方法相比,它避免了误判区域的问题,便于校正。
