“圭璋之品,经世长才”——明季歙县傅岩探微

明季,歙县知县傅岩为了应对干旱等自然灾害,发官府库银收购米粮,低价卖给民众,又颁布告示规范商民双方的行为,为救荒营造了一个良好的社会环境;严格遵守中央重武备的政策,在任期间大力整饬武备,严行保甲,有力地维护了社会秩序;针对社会上出现的诸多不法现象和不良习俗,颁布禁令和告示,进行整顿和改革,使社会风气为之一新。在明末时局动乱和歙县自然灾害严重的情况下,傅岩能够取得如此巨大的政绩,并得到皇帝、同僚和民众的认可,足以显示其"圭璋之品,经世长才。"

上皮生长因子预防心脏术后心包粘连的实验及临床研究

目的探讨上皮生长因子(EGF)对心脏术后心包粘连的预防作用.方法术中对犬心包内喷洒上皮生长因子3个月后,观察心包粘连情况;选先天性心脏病、房缺及室缺病人40例,术中心包内喷洒上皮生长因子,术后6个月、12个月经CT检查,判定心包粘连、增厚结果.结果在动物实验和临床研究中,实验组粘连程度显著低于对照组(P<0.01).结论 EGF心包内应用有明显预防心脏术后心包粘连的作用.     

Detecting myocardial ischemia with 2-D CVIB imaging method--an in vivo animal experiment study

A 2-D cyclic variation of integrated backscatter (CVIB) imaging method was established for detecting myocardial ischemia. To demonstrate the feasibility and validity of this method, animal experiments were conducted. Acute myocardial ischemia was induced by occluding left anterior descending coronary artery in 10 anesthetized open-chest dogs. While scanning the normal hearts and the ischemic hearts with a B scanner, digital radiofrequency data were acquired by a real-time acquisition system in synchronism. The offline analysis to the radio-frequency signal with the 2-D CVIB imaging method was performed to verify the consistency between the imaging result and the design of the experiment. In addition, 4 dogs in experiment were treated with the heart pacemaker in order to investigate the influence of changing in heart rate on the detection of ischemic myocardium with the proposed method. The experimental result showed that the 2-D CVIB imaging method succeeded in detecting the ischemic myocardium and is a new non-invasive way for the cardiologists to both quantitatively and visually evaluate the contractile performance of the myocardium.

Finding global minima with a new dynamical evolutionary algorithm

A new dynamical evolutionary algorithm (DEA) based on the theory of statistical mechanics is presented. This algorithm is very different from the traditional evolutionary algorithm and the two novel features are the unique of selecting strategy and the determination of individuals that are selected to crossover and mutate. We use DEA to solve a lot of global optimization problems that are nonlinear, multimodal and multidimensional and obtain satisfactory results.

抗人绒毛膜促性腺激素（HCG）单克隆抗体的研制和特性分析

以HCG为抗原,免疫BALB/c小鼠,取其脾细胞与小鼠Sp2/0—Ag14骨髓瘤细胞融合,经反复筛选和再克隆化,获得8株能稳定分泌抗HCG特异单克隆抗体的杂交瘤细胞株。对其中6个高效价单抗进行了特异性和抗原决定簇检测,选出两个抗相距较远不同决定簇的单抗(2D_4,4F_4)作进一步特性分析。结果显示:免疫球蛋白亚类鉴定,2D_4为IgGl亚类,4F_4为IgG2a亚类;亲和力常数(K_(affi)),2D_4为5.41±0.94×10~(-10)mol/L,4F_4为1.37±0.33×10~(-9)mol/L。证实该两种单克隆抗体可用于研制有关临床诊断试剂盒。
