目的探讨膀胱镜检查后患者发生尿路感染的危险因素,为有效控制患者发生尿路感染提供依据。方法选取2014年7月-2015年6月在医院接受膀胱镜检查的患者96例,采用回顾性的分析方法分别统计患者的年龄、性别、有无合并症等,分析患者发生尿路感染的危险因素。结果 96例患者中有30例患者确诊为尿路感染,感染率为31.25%;检测出病原菌48株,其中以革兰阴性菌为主,共30株占62.50%,其次为革兰阳性菌16株占33.33%,真菌2株占4.17%;选取主要的革兰阴性菌、革兰阳性菌以及真菌进行药敏试验,结果显示其对大多数抗菌药物均产生一定耐药性;灌注次数≥6次、年龄≥65岁、有前列腺增生、留置导尿管以及糖尿病等基础疾病是膀胱镜检查后患者发生尿路感染的危险因素;在单因素分析的基础上,将有统计学意义的灌注次数、年龄、性别、糖尿病、前列腺增生以及留置导尿管等变量因素,采用logisctic进行回归分析,筛选出独立危险因素,按照OR值的大小,依次为年龄大、糖尿病、前列腺增生以及留置导尿管。结论术前对前列腺增生及糖尿病等基础疾病患者进行治疗,严格控制留置导尿管的适用指征和无菌操作,有效减少患者尿路感染。

Based on the fact that the quantum mechanical version of Hankel transform kernel（the Bessel function） is just the transform between ｜q, r〉 and（s, r′｜, two induced entangled state representations are given, and working with them we derive fractional squeezing-Hankel transform（FrSHT） caused by the operator e（-iα）（a1-a-2-＋a-1a-2）e-（-iπa2-a2）, which is an entangled fractional squeezing transform operator. The additive rule of the FrSHT can be explicitly proved.
