无法鉴定的

Genetic dissection of QTLs for yield traits were further conducted for the genomic regions harboring Pi25. It was found that two or more linked QTLs for yield traits were located in this region, and they had effects on each of the 6 yield traits studied. It remains unclear that the genetic drag between Pi25 and yield QTLs was solely resulted from unfavorable linkages, or partially ascribed to pleiotropism of Pi25.

应用2期2重复的小区产量性状鉴定试验，进一步剖析产量性状QTL，发现Pi25两侧区间影响所有6个产量性状，且该区间存在2个以上控制产量性状的不同基因座，但尚无法判定研究群体存在的遗传累赘是全部源于抗病基因与产量性状QTL的不利连锁，还是部分源于Pi25的一因多效。

But within all this realm of choicelessness,we do choose how we shall live:courageously or in cowardice,honorably or dishonorably,with purpose or in drift.

但是在这些无法选择之中，我们的确可以选择终结的生活方式：是勇敢无畏还是胆小怯懦，是光明磊落还是厚颜无耻，是目标鉴定还是随波逐流。

Conclusion1 Critically ill patients with indwelling catheters were of the high positive rate of microorganisms,and microorganism spectrum was of special properties;BF formed mainly inside the catheter,the occurrence rate of BF inside the catheter was high and the formation time was short;Changes on catheters and the result of microorganisms was positively correlated with the BF formation.2 Indwelling catheter time was the independent risk factors for the BF formatiom, while age、APACHEⅡscore、sex、urine sugar and the types of antibiotic usage were the potential risk factors for the BF formation;Nurses should perfect the catheter measures for critical ill patients,emphasis on the assessment of risk factors of BF formation,and implement special care in high-risk patients.3 In the early stage of BF formation,irrigation could play the role of eradicative BF effectively;While later,it couldn't,but it can delay the speed of BF formation and maturation;In the choice of washing methods,injection type washing method is superior to infusion.

结论1重危患者留置尿管微生物培养阳性率高，且微生物菌谱具有特殊性；重危患者尿管表面BF主要在尿管内壁形成；内壁BF的发生率高，形成时间短；肉眼观察尿管表面改变情况以及微生物鉴定结果与BF形成呈正相关。2尿管留置时间是重危患者留置尿管表面BF形成的独立危险因素；年龄、APAcHEⅡ评分、性别、尿糖定性以及抗生素使用种类是其可能的危险因素；护理过程中应完善重危患者尿管护理措施，注重对BF危险因素的评估，并对高危患者实施重点护理。3 BF形成早期，冲洗能发挥较好的清除作用；BF形成后期，冲洗无法彻底清除尿管表面BF，但冲洗能延缓BF形成与成熟的速度；在冲洗方式的选择上，注洗式冲洗法对尿管BF的清除效果优于输注式冲洗法。

Most techniques in vivo monitoring the distribution, prolification and migration of transplanted cells. To objectively evaluate curative effect after cells transplantation, most techniques for the study of stem cell transplantation in animal models require histological analysis to determine the fate and migration of cells.

监测活体内移植入细胞的分布、增殖、迁移的方法虽然有多种，但传统方法都需要在离体状态下进行组织学切片分析和鉴定，无法准确地观察植入细胞的生长分化情况，从而难以对干细胞移植术的疗效作出客观评价。

However, the recombinant yeast could not grow on the traditional tributyrin plate because this kind of medium is lack of essential nutrients for yeast growth.

而传统的三丁酸甘油酯平板缺乏有效营养成分，重组酵母无法生长；橄榄油平板灵敏度较低，低脂肪酶活力的重组酵母不能产生变色圈，这给产脂肪酶基因工程菌的鉴定带来了困难。

更重要的是，植株形态性状无法用于种子贸易中的品种鉴定。

Moreover, MSCs are easy to transfect and express the exogenous gene, so they will be widely used in cell therapy and genetic therapy.

但目前采用的体外分离培养无法得到单克隆的细胞成分，也缺乏可靠的鉴定标准，不同来源的间充质干细胞有何差异等间题亟待解决。
