基于基因表达式编程的公路工程造价预测模型

基因表达式编程作为新型的人工智能数学建模方法,具有较强的函数发现能力和较高的搜索效率．针对公路工程造价预测特点和已有预测模型的不足,求解基于GEP的公路工程造价预测模型．根据工程造价的组成原理筛选确定11个公路工程特征因素,用15组公路工程数据作训练样本和验证样本,在设定好GEP算法的构成要素的前提下,使用Visual Basic语言表达GEP算法,求解公路工程造价预测模型．通过敏感性分析模型的可行性,用比较图和4个统计指标值对模型进行评价．结果表明,预测模型所得结果与工程实践相吻合,且预测值与实际值的相对误差≤5.9%,满足预测精度≤10%的要求,预测精度高,该模型具有较好的应用价值．     

DIG－DNA探针检测宫颈癌组织中HPV－16的E_7转化基因

应用地高辛配基（Ｄｉｇ－１１－ｄＵＴＰ）标记人乳头瘤病毒１６型（ＨＰＶ－１６）Ｅ７转化基因作探针，分别检测了宫颈癌活检组织、宫颈炎及正常宫颈脱落细胞ＤＮＡ。其检出率为：宫颈癌中４２．１％（２４／５７）、宫颈炎中２．５％（１／３９）、正常宫颈中５．５％（１／１８）。宫颈组织中ＨＰＶ－１６Ｅ７转化基因的检出率较高，提示该转化基因与宫颈癌的发生可能密切相关。本研究也证实ＤＩＧ配基标记的Ｅ７基因探针具有特异、敏感、安全、稳定和能反复使用的优点，适合基层使用。

基于基因遗传算法的车轮踏面优化

结合遗传优化算法与车辆动力学仿真,对车轮踏面进行动态优化。建立了与车辆系统关键动力学指标相对应的适应度函数,根据优化目标选择加权系数形成综合适应度函数。以磨耗形踏面作为父本踏面,生成初始踏面群体,使用动力学软件SIMPACK计算不同踏面个体对应的动力学指标,用基因算法对各踏面个体的适应度进行评价,选择适应度较高的踏面进行交叉和变异操作形成新的踏面群体,如此进行数代遗传优化得到了适应度较高的踏面形状。

应用PCR技术克隆人乳头瘤病毒16型E6基因

为进一步研究与宫颈癌发生密切相关的人乳头瘤病毒16型E6基因的转化作用,我们运用PCR技术扩增HPV16 E6 DNA,以pUC—19为载体,大肠杆菌了JM103为宿主菌,组建了质粒pRCE6经限制性核酸内切酶和Southern转印杂交证实,其插入片段约为0.5Kb,含有全部HPV16 E6序列。该质粒的组建为检测HPV感染中mRNA转录提供了特异性的早期基因探针。同时为进一步研究HPV16 E6基因的转化作用及转化蛋白打下基础。

Identification of differentially expressed genes in two new human bladder carcinoma cell lines

Objective To screen and identify differentially expressed genes in two new human urothelial carcinoma cell lines, BLS-211 and BLX. Methods Suppression subtractive hybridization （SSH） was used to createa subtracted library, and clones were sequenced. Results Totally 13 over-expressed genes in BLX and 9 in BLS-211 cells were obtained, respectively. Among them, 18 were known genes and 4 were new ESTs （Expressed Sequence Tag）, and were collected by GenBank dbEST database （The access number was EB390424-7）. Conclusion SSH is a powerful method for the identification of differentially expressed genes. The differential expression of some BCG-associated genes in different ceils may be related to the different responses to clinical BCG therapy. The identified new ESTs can be cloned for full length to further study their functions.
