The cable-strut structural system is statically and kinematically indeterminate. The initial pre-stress is a key factor for determining the shape and load carrying capacity. A new numerical algorithm is presented herein for the initial pre-stress finding procedure of complete cable-strut assembly. This method is based on the linear adjustment theory and does not take into account the material behavior. By using this method,the initial pre-stress of the multi self-stress modes can be found easily and the cal-culation process is simplified and efficient also. Finally,the initial pre-stress and structural performances of a particular Levy cable dome are analyzed comprehensively. The algorithm has proven to be efficient and correct,and the numerical results are valuable for practical design of Levy cable dome.

The purpose of this study is to investigate the frequency of prostate cancer （Pca） discovered incidentally in radical cystoprostatectomy specimens in Asia and to determine the feasibility of prostate-sparing cystectomy （PSC） for Asian patients. Ninety-two male bladder cancer patients who underwent radical cystoprostatectomy at our center between January 2003 and January 2008 were included in this study. The mean age of patients was 67.1 years （range： 32-75 years）. Prostate-specific antigen （PSA） levels and digital rectal examination （DRE） results before surgery were obtained retrospectively. Prostates of all patients were embedded and sectioned at 5-mm intervals. The same pathologist examined the prostatic tissues from radical cystoprostatectomy specimens. Finally, a structured literature review was performed using MEDlinE and PUBMED to estimate the occurrence of incidental Pca in Asia. Of the 92 patients, 3 （3.3%） were found to have Pca; in one out of three （33.3%） patients the disease was clinically significant due to a Gleason grade 4 carcinoma. Eight articles were included in our review. The overall incidence of Pca discovered incidentally in radical cystoprostatectomy specimens in Asia was 9.9% （64/642）. When age was restricted to 〈 60 years, only 7 out of 222 （3.2%） patients were found to have synchronous Pca, and none of the cases was clinically significant. The occurrence of Pca in radical cystoprostatectorny specimens in Asia is much lower than that in Western countries. PSC might be feasible for Asian patients under a strict preoperative selection.

The skeleton is the most common metastatic organ in patients with prostate cancer （PCa）. Non-invasive biomarkers that can facilitate the detection and monitoring of bone metastases are highly desirable. We designed this study to assess the expression patterns of serum miR-141 in patients with bone-metastatic PCa. Serum samples were collected to measure the miR-141 level in 56 patients, including six with benign prostatic hyperplasia （BPH）, 20 with localized PCa and 30 with bone-metastatic PCa （10 with hormone-naive PCa, 10 with hormone-sensitive PCa and 10 with hormone-refractory PCa）. A bone scan was performed for each patient with PCa to assess the number of bone lesions. The quantification of serum miR-141 levels was assayed by specific TaqMan qRT-PCR. The results showed that serum miR-141 levels were elevated in patients with bone metastasis （P〈O.O01）. There was no statistically significant difference in the serum miR-141 levels between patients with BPH and patients with localized PCa. Using Kendall＇s bivariate correlation test, both the Gleason score and the number of bone-metastatic lesions were found to correlate with serum miR-141 levels （P=0.012 and P〈O.O01, respectively）. The serum miR-141 level was found to be positively correlated with alkaline phosphatase （ALP） level in patients with skeletal metastasis, using Pearson＇s bivariate correlation test. No relationship was found between the serum miR-141 level and the serum prostate-specific antigen （PSA） level. We concluded that serum miR-141 levels are elevated in patients with bone-metastatic PCa and that patients with higher levels of serum miR-141 developed more bone lesions. Furthermore, serum miR-141 levels are correlated with serum ALP levels but not serum PSA levels.

Barn Burning （1939）, one of William Faulkner＇s outstanding short stories, is not only about the struggles between different classes, but also depicts the boy＇s initiation into manhood after he sees his father＇s rash and irrational revenge activities. The boy protagonist＇s constant dilemma is between whether to protect his father＇s authority due to the old fierce blood tie or to disclose his father＇s quasi-criminal attempts according to his own standard of justice. Based on close reading of the text, this paper aims to make a detailed analysis of the different factors （paternalism and his own idea of justice） that influence the boy＇s choices at different stages. After the long-time struggle, the boy finally chooses to follow his own standards of right and justice, which signifies his gradual initiation into manhood.

以大跨度门式桁架结构为研究对象,用时程分析法考察了多点输入对不同跨度结构地震反应的影响.时程分析结果表明,行波效应与部分相干效应对结构地震反应的影响基本一致;水平多点输入的考虑将提高跨中杆件的地震反应.结合门式桁架结构的具体结构形式,介绍了基于振型组合理论的平均反应谱法(ARSM法),类似于传统的反应谱法,ARSM法的优点在于通过简单的振型组合可计算出多点输入下门式桁架结构的最大地震反应.时程分析结果和ARSM法计算结果的比较验证了ARSM法的正确性.基于ARSM法对多点输入下门式桁架结构的地震反应作了更深入地分析,并对这类结构的多点输入抗震设计提出了具体建议.

以两种典型空间结构为研究对象,考察了竖向地震作用下结构的地震反应以及竖向多点输入对结构地震反应的影响。分析表明,竖向地震一致输入在门式桁架结构和周边支承网壳结构中将产生较大的内力,因此竖向地震作用在这两类结构的抗震设计中是必须考虑的。竖向多点输入对门式桁架结构地震反应的影响很小,这种影响在结构抗震设计中可以忽略;对周边支承网壳结构来说,竖向多点输入使得网壳结构的地震内力降低,同时由于拟静力作用在支承结构中产生的内力较小,多点输入对支承结构的地震内力影响也很小。
