International Journal of Plant Engineering and Management 2010年第2期15卷 83-89页

作者： WANG wei-hu LU Zhen-zhou LU Yuan-bo School of Aeronautics Northwestern Polytechnical University Xi'an 710072 P. R. China

The reliability and reliability sensitivity （ RS ） models are presented for the engineering problem involving truncated correlated normal variables （CNV）, and in the case an adaptive radial based sampling is used to analyze the reliability and the RS. In the presented models, the truncated CNV is transformed to general CNV, and the value domains of the truncated CNV are treated as multiple failure modes, then the reliability and the RS with the truncated CNV are transformed to the general cases, on which an e^cient radial based sampling is used to analyze the trans- formed reliability and RS. An adaptive strategy is employed to search for the optimal radial in the sampling, by which the robustness of the method is improved. After the model concepts and the detailed implementation are given, several examples are presented to demonstrate the feasibility of the model and the efficiency of the solutions.

目的探讨在中国肺腺癌患者中,吸烟对组织形态学特征及预后的影响。方法 266例原发性肺腺癌患者按照2011年肺腺癌国际肺癌研究协会/美国胸科学会/欧洲呼吸学会(International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society, IASLC/ATS/ERS)新分类方法进行组织学亚型重新分类,分析吸烟状况等各种临床病理特征与组织学亚型的关系以及对患者术后生存期的影响。结果组织学亚型主要为腺泡状为主型(30.1%)、乳头状为主型(26.7%)、实体状为主型(25.9%)、贴壁状为主型(11.7%)。吸烟状况与组织学亚型有关,实体状为主型患者组中,吸烟患者所占比例高于不吸烟患者,而其它亚型组中则均为不吸烟患者所占比例更高(P<0.05)。Cox比例风险回归模型分析显示,在整体患者中,组织学亚型及TNM分期是术后生存期的预测因子;将患者分为吸烟患者和不吸烟患者,TNM分期在两类患者中均为术后生存期的预测因子,而组织学亚型则只在吸烟患者中显示对预后有显著性影响[标准偏回归系数(B)=0.898,相对危险度(RR)=2.455],与非实体状为主型患者比较,实体状为主患者的预后明显较差。结论吸烟与实体状为主亚型关联,并进一步对预后造成影响。
