目的:比较镜检法和尿液分析仪检测白细胞的差异。 方法: 用两种方法测定900例尿液标本中的白细胞,并对其结果进行比较分析。结果:两种方法检测结果有明显差异(Plt;005),以镜检法为标准,尿液分析仪检测白细胞假阳性率为169%,假阴性率为158%。结论: 检测尿液白细胞时镜检法和尿液分析仪尽量结合应用,以减少假阴性率和假阳性率,保证检验结果的准确性。
ObjectiveTo summarize the current status and advances of sentinel lymph node biopsy (SLNB) technique in breast cancer. MethodsThe pertinent domestic and overseas literatures were reviewed and the localization, harvest, status assessment, indications, and complications of SLNB were analyzed. ResultsSLNB could accurately locate and pick out sentinel lymph node (SLN) in breast cancer. The development on imaging examination and pathological techniques promoted the assessment of SLN, and the indications of SLNB were expanding. The complication rate of SLNB was low and the technique could accurately predict axillary lymph node staging and direct selective axillary lymph node dissection. ConclusionsSLNB has been an important method of surgical therapy in breast cancer, but the operation process needs to be further standardized to decrease the false negative rate. Continuative attentions shall be paid to the problems such as the false positive and controversial indications.
Objective To detect the false-positive results of cumulative meta-analyses of Cochrane Urology Group with the trial sequential analysis (TSA). Methods The systematic reviews of Urology Group of The Cochrane Library were searched to collect meta-analyses with positive results. Two researchers independently screened literature and extracted data of included meta-analyses. Then, TSA was performed using TSA software version 0.9 beta. Results A total of 11 meta-analyses were included. The results of TSA showed that, 8 of 11 (72.7%) meta-analyses were potentially false-positive results for failing to surpass the trial sequential monitoring boundary and to reach the required information size. Conclusion TSA can help researchers to identify the false-positive results of meta-analyses.
