The diverse types of tracheary elements and perforation plates in secondary xylem of A. asiatica show that previous knowledge about the tracheary elements and perforation plates in secondary xylem of A. asiatica is not complete and thus any inferences about the aboriginality and evolution of a taxon made depending on these traits are not reliable.

根据类叶升麻次生木质部中多变的管状分子类型，认为以往积累的有关毛茛科植物管状分子类型及导管穿孔板类型是不全面的，因此以该性状为参考作出的有关某一个类群的原始性和进化性的推论也是不可靠的。

The ideal time-saver for busy clinicians, this handy guide delivers a practical "how-to" perspective on diagnosis and treatment for a range of commonly encountered childhood infections—from otitis media, sinusitis, and urinary tract infection...to hepatitis, cervical adenitis, pediatric tuberculosis, pneumonia, catheter infection, and more.

Among them, 20 patients were candidates of valve replacement and 18 PDA and pericarditis had their blood samples taken before operation,and 1,2,24 and 48 hours after closure of thorax for measurement of concentrations of CK、CK-MB and TnT,together with ECG recording. Results Of the 60 patients, concentrations of cTnT before operation were normal; 2 hours after aortic unclamping, the correlation coefficient between cTnT and aortic clamping was r = 0.873( P＜0.01), the regression analysis showed Y = 0. 019X-0. 026. Of the 20 patients, ECG showed the myocardium was ischemic; CK、CK-MB and cTnT all rose significantly, reaching the peak after closure of thorax. Of the 18 patients, the ECG and cTnT before operation and after closure of thorax were normal; except 2 patients with pericarditis.

结果 60例瓣膜手术患者术前cTnT均在正常值范围内，主动脉开放后2 h时，阻断时间和cTnT的相关系数为r=0.875(P＜0.01)，回归方程为Y=0.019X-0.026；其中20例瓣膜手术患者心脏经过阻断后，心电图有缺血性改变，周围血液中的CK、CK-MB和cTnT均有明显升高，分别在关胸后2 h达到高峰，数值分别为术前的12.6、9.2和257倍；18例行动脉导管结扎和心包剥脱术的患者术前和关胸后的心电图和血液中的cTnT均正常，CK和CK-MB除2例心包炎患者关胸后出现明显变化外，余均未见改变。

The bigger top tension will cause the wellhead to be over-pulled and increase the probability of wellhead collapse. As the mean drifting of drilling vessel or platform increases, the wellhead displacement and bending moment nearly linear enlarges. The greater current velocity may result in wellhead instability because of its limited bearing moment capacity. Therefore the drifting control is very important to subsea wellhead stability. The wellhead stability may be improved by taking measures such as enhancing the conductor bending strength, controlling scour depth on seabed, getting geological data sampling of shallow formations.

算例分析表明，水下井口的横向偏移及弯矩随张力比和海流流速的增加而大幅增大，顶张力过大会引起井口稳定性变差；随着钻井船或平台漂移量的增加，井口的横向偏移和弯矩近似线性增加，控制好钻井船或平台的漂移非常重要；由于井口承受弯矩的能力有限，较大海流流速情况下可能造成井口失稳；提高导管抗弯强度、控制泥线处管柱冲刷、获取浅部地层的取样数据等措施可以增强井口稳定性。

It can accurately record the images of the soft tissue with different penetrability. Especially, it is able to catch small "sand-shaped" calcified focus which is of segment significance in the mammary gland duct. This technology, combined with directional piercing cytology inspection, can accurately determine the confinement of the breast lump, and detect all breast tubercles.

钼钯摄片能精细地记录下不同穿透能力的软组织留下的影像，特别是能捕捉到对乳腺导管内具有重要着段意义的微小泥沙样的钙化病灶，结合定位刺穿细胞学检查，则能高准确地确定乳房肿块位置的限制，能发现直径在一毫米的乳房结节。

Rat AAA model was made by perfusion PPE elastase through the abdominal aorta, and the specimen was obtained on postoperativeday 3, 7, 14, 28, respectively. Specific elastic fiber staining was used to observe the disruption of elastic fiber in aortic wall. Immunohistochemistry staining of CD68 was applied to observe the microphage infiltration. The in tisu hybridization and western blot of MCP-1 and MMP-2 were used to study the expression of mRNA and protein. Thus we can analyze the facilitated function of MCP-1 gene to the microphage adherence and infiltration on the earlier AAA.
