对３０例非细菌性前列腺炎（ＮＢＰ）患者的前列腺按摩液（ＥＰＳ）沙眼衣原体（ＣＴ）进行了聚合酶链反应（ＰＣＲ）检测，并与经二乙氨基葡聚糖处理的ＨｅＬａ细胞培养法进行对比研究。结果发现，６例ＰＣＲ和细胞培养双阳性，２１例ＰＣＲ和细胞培养双阴性，３例两种检测结果不一致，包括２例ＰＣＲ阳性但培养阴性，１例培养阳性但ＰＣＲ阴性。将ＰＣＲ与细胞培养进行比较，ＰＣＲ的敏感性为８５．７％，待异性为９１．３％，阳性预报值为７５．０％，阴性预报值为９５．５％。提示ＰＣＲ是一种能对ＣＴ感染进行简便快捷、敏感特异和早期诊断的无创性检测技术，尤其适合于临床怀疑ＣＴ为ＮＢＰ的可能致病体的筛选诊断，值得临床推广应用。
30 cases of non-bacterial prostatitis (NBP) in patients with prostate massage liquid (EPS) Chlamydia trachomatis (CT) was detected by polymerase chain reaction (PCR), and diethylamino dextran treatment of HeLa cell culture Conduct a comparative study. The results showed that 6 cases of PCR and cell culture double positive, 21 cases of PCR and cell culture double negative, three cases of two inconsistent results, including two cases of PCR positive but negative, one positive but negative PCR. PCR and cell culture were compared, PCR sensitivity was 85.7%, to be the opposite sex was 91.3%, positive predictive value was 75.0%, negative predictive value was 95.5%. Prompt PCR is a noninvasive detection technique that can be used to detect CT infection easily, quickly, sensitively and early diagnosis. It is especially suitable for the clinical diagnosis of suspected pathogens which CT is NBP. It is worthy of clinical application.
