Objective To compare outcomes of patients undergoing either open or endoscopic carpal tunnel release for the treatment of idiopathic carpal tunnel syndrome. Methods A prospective, randomized study was performed on 70 hands in 62 patients with idiopathic carpal tunnel syndrome from April 2000 to April 2004. Either open (36 hands in 30 patients) or endoscopic (34 hands in 32 patients) carpal tunnel release was performed randomly. Symptom improvement, complications, and the time of operation, in-hospital stay, and return to work between the two groups were assessed with average 2 years of follow-up. The electromyography was tested pre- and 3 months post-operation. Results There were no significant differences between the two surgical groups with regard to postoperative improvements of symptom, electromyography tests, and the incidence of complications. But it was statistically less in the rate of scar tenderness, the time of operation, in-hospital stay, and return to work in the endoscopic group compared with the open group (P<0.05). Conclusions The endoscopic carpal tunnel release is a reliable method in the treatment of idiopathic carpal tunnel syndrome. And it has the advantages of slight scar tenderness, less operation time, less in-hospital stay, early functional recovery, safety, and high satisfaction rate compared with open methods.

The healthy and rapid development of the controlled cooling technology was hampered by the uneven cooling phenomenon. During the process of hot plate production,the homogeneous cooling along the length direction of plate was constrained by lots of factors. And because the speed was a flexible control parameter,the calculation method of optimal speed profile was developed based on the measured start cooling temperature and its matrix equation was solved by the Cholesky decomposition method. The optimal speed profile was used in online control system. As a result,the temperature distribution along the plate length direction was relatively uniform,and 95% of measured final cooling temperature difference from the target temperature 700 ℃ was controlled within ±20 ℃.

Journal of Genetics and Genomics 2008年第2期35卷 119-127页

作者： Kunpu Zhang Jichun tian Liang zhao Shanshan wang State Key Laboratory of Crop Biology Group of Quality Wheat Breeding of Shandong Agricultural University Tai＇an 271018 China

Quantitative trait loci （QTLs） for plant height in wheat （Triticum aestivum L.） were studied using a set of 168 doubled haploid （DH） lines, which were derived from the cross Huapei 3/Yumai 57. A genetic linkage map was constructed using 283 SSR and 22 EST-SSR markers. The DH population and the parents were evaluated for wheat plant height in 2005 and 2006 in Tai＇an and 2006 in Suzhou. QTL analyses were performed using the software of QTLNetwork version 2.0 based on the mixed linear model. Four additive QTLs and five pairs of epistatic effects were detected, which were distributed on chromosomes 3A, 4B, 4D, 5A, 6A, 7B, and 7D. Among them, three additive QTLs and three pairs of epistatic QTLs showed QTL×environment interactions （QEs）. Two major QTLs, Qph4B and Qph4D, which accounted for 14.51% and 20.22% of the phenotypic variation, were located similar to the reported locations of the dwarfing genes Rhtl and Rht2, respectively. The Qph3A-2 with additive effect was not reported in previous linkage mapping studies. The total QTL effects detected for the plant height explained 85.04% of the phenotypic variation, with additive effects 46.07%, epistatic effects 19.89%, and QEs 19.09%. The results showed that both additive effects and epistatic effects were important genetic bases of wheat plant height, which were subjected to environmental modifications, and caused dramatic changes in phenotypic effects. The information obtained in this study will be useful for manipulating the QTLs for wheat plant height by molecular marker-assisted selection （MAS）.

箱板式钢结构是一种可快速装配的新型结构体系，其设计理念来源于船舶上部建筑结构。在前期有限元分析的基础上，设计制作了2个三层单开间箱板式钢结构空间模块单元试件，并进行了拟静力加载试验。研究了试件的破坏过程、破坏模式、承载力、滞回性能等，重点分析了有无角部加强构造措施对试件抗震性能的影响。研究表明：箱板式钢结构空间模块单元的破坏始于试件角部屈曲，其最终破坏时模块单元的角部撕裂、墙板屈曲，模块结构具有较高的承载力和良好的耗能能力；模块结构中的角部加强构造措施起到了类似传统钢板剪力墙中框架柱的作用，使钢板墙拉力带发育更充分，且在一定程度上使钢板墙利用了屈曲后强度；角部加强构造措施提高了试件的极限承载力，改善了试件延性性能和耗能能力；角部加强构造措施对箱板式钢结构而言是一种有效的抗震性能提升措施。

提出一种带加劲肋和混凝土约束面板的组合钢板墙，主要应用于箱板钢结构装配式住宅底部加强区。设计制作了2个1／3比例的钢板墙试件，1个为带竖向加劲的钢板墙，1个为带竖向加劲和混凝土约束面板的组合钢板墙，并进行了低周反复加载试验。研究了试件的破坏过程、破坏模式、承载力、变形性能等，重点分析了混凝土约束面板对试件抗震性能的影响。试验结果表明：带竖向加劲钢板墙试件的破坏始于钢板和加劲肋的屈曲，组合钢板墙试件的破坏始于钢板的屈曲和混凝土板产生裂纹；最终破坏时，带竖向加劲肋的钢板墙上形成稀疏的大尺寸交叉拉力带，而组合钢板墙则是在加劲肋与螺栓围成的小区格内形成“棱台”状交叉拉力带；相比于只带竖向加劲肋的钢板墙，组合钢板墙承载力更高，延性更好，滞回曲线相对饱满，耗能能力更强，抗侧刚度和承载力退化更缓慢。
