UF-1000i全自动尿有形成分分析仪对尿路感染的诊断价值

Objective To evaluate the application value of UF-1000i automated urine formed elements analyzer in the diagnosis of urinary tract infection. Methods 150 urine specimens were analyzed using the UF-1000i in parallel with detection of leukocyte, yeast-like fungus, and bacteria. These detection results were collected for evaluation of urinary tract infection and scatter grams were recorded. At the same time, these samples were cultured for bacterial identification, which results were compared with that of the UF-1000i. The clinical diagnose criteria of the UTI was performed as golden standard. As compare with results obtained with UF-1000i, the sensitivity and specificity of UF-1000i for diagnosis of urinary tract infection were evaluated, and the consistency were analyzed among scatter grams, bacterial culture and final diagnosis. Results The statistical results from 146 specimens showed that the positive rate of UF-1000i was 32. 9% (48/146), the positive rate of urine culture is 28. 8% (42/146). There was no significant statistical difference found (χ2 = 1.79 ,P = 0. 18 )and Kappa test showed a considerable consistency (K = 0. 775 6). The UF-1000i detection results showed the sensitivity 76. 0% ( 38/50 ), specificity 89. 6% ( 86/96 ), positive predictive value 79. 2% ( 38/48 ) and negative predictive value 87. 8% ( 86/98 ), respectively. The distribution of coccus and bacilli obtained from the UF-1000i testing was basically in accordance with the results of bacterial culture. Conclusion The "UTI-information" of UF-1000i is very important for the diagnosis of urinary tract infections.

细菌生物膜厚度和面积对人耳听力的影响

依据临床健康志愿者右耳的CT扫描结果,将CT扫描数据数值化导入PATRAN软件进行人耳三维有限元模型的重建,并用NASTRAN软件对该模型进行频率响应分析。通过对正常人耳结构进行频率响应分析得出数据与实验数据吻合,验证了模型的正确性。结合临床中耳炎病症实际情况,研究细菌生物膜的成长阶段对人耳听力的影响。结果表明：在不同声压相同的频率段,细菌生物膜的厚度变化对人耳听力的影响是相同的。在相同声压不同频率段,细菌生物膜的厚度增加会引起镫骨振幅和速度降低,在较低频率段镫骨振幅和速度下降幅度较大,下降的最大值为1.64 dB;在较高频率段镫骨振幅和速度下降幅度较小,下降的最大值为1.04 dB。在不同声压作用下,在相同的频率段细菌生物膜的面积增加会引起镫骨振幅和速度降低。在100～1 000 Hz频率段镫骨振幅和速度的下降幅度较小,下降的最大值为0.18 dB。在1000～10 000 Hz频率段镫骨振幅和速度的下降幅度较大,下降的最大值为2.26 dB。细菌生物膜厚度或面积增加都会使人耳听力下降,厚度增加在低频时比高频时下降更多,而面积增加则刚好相反。
