目的:研究经尿道膀胱肿瘤剜除术的安全性及有效性,并分析影响非浸润性膀胱癌复发的因素。方法:选取70例非浸润性膀胱癌患者,随机分为经尿道膀胱肿瘤切除术组(transurethral resection of bladder tumor,TURBT)和经尿道针状电极膀胱肿瘤...目的:研究经尿道膀胱肿瘤剜除术的安全性及有效性,并分析影响非浸润性膀胱癌复发的因素。方法:选取70例非浸润性膀胱癌患者,随机分为经尿道膀胱肿瘤切除术组(transurethral resection of bladder tumor,TURBT)和经尿道针状电极膀胱肿瘤整块剜除术组(en bloc resection of bladder tumor,ERBT),每组35例患者,比较两组患者的手术时间、术后住院时间、发生闭孔反射情况、膀胱冲洗时间、留置导尿管时间及术后复发情况,并对所得数据进行统计学分析。结果:两组手术时间、术后住院时间及发生闭孔反射情况比较存在统计学差异,在术后患者膀胱冲洗的时间及留置导尿的时间方面无统计学差异。通过分析影响术后复发的因素,我们发现肿瘤大小、年龄及肿瘤病理分级比较具有统计学意义,而手术方式、手术时间、膀胱冲洗时间、留置尿管时间及年龄比较无统计学意义。通过对影响复发的多因素logistic回归分析,结果显示年龄和病理组织分级是影响患者复发的因素。结论:ERBT是一种治疗非浸润性膀胱癌安全有效的术式,值得临床推广。展开更多
Ninety wild strains of Agaricus collected in China,including 44 strains preliminarily identified as Agaricus bisporus by isozyme electrophoresis,were studied using SRAP and ISSR techniques.Eighteen specific SRAP bands...Ninety wild strains of Agaricus collected in China,including 44 strains preliminarily identified as Agaricus bisporus by isozyme electrophoresis,were studied using SRAP and ISSR techniques.Eighteen specific SRAP bands and 12 specific ISSR bands were scored,and a cluster dendrogram was constructed.The 90 wild strains of Agaricus were separated into two major groups,the first consisting of wild strains of A.bisporus and the second consisting of other Agaricus strains.Forty-one wild strains of A.bisporus collected in Sichuan and Tibet formed four groups according to the geographical location of the collection area.White A.bisporus strains from Xinjiang and Tibet(Xinjiang Wild,AgX04 and AgX042)exhibited unique band patterns resulting in lower similarity coefficient values(10%～13%)when compared with brown or light-brown A.bisporus strains.展开更多
