B超发现的未能扪及的睾丸肿块

探讨对于临床上体检不能扪及而由Ｂ超检查发现的睾丸肿块的诊治方法。对方法对有关病例的超声检查表现及其病理结果进行回顾性分析。结果近１０年来６００多例因子各种原因行阴囊超声检查的患者中,共发现１４例１６处体检未能扪及的睾丸肿块。患者平均年龄４２．４岁,肿块直径平均１２．１ｍｍ,除１例外其余肿块均表现为低回声团块。

Objective To find out the expression and significance of MXR7 mRNA in human hepatocellular carcinoma. Methods The 32 P labeled and purified PCR product of MXR7 cDNA was taken as probe. MXR7 mRNA expression was detected by Northern blot analysis in 30 samples of preoperatively untreated HCC and corresponding surrounding non cancerous hepatic tissue,and 12 normal liver tissues confirmed pathologocally. Results The frequency of MXR7 mRNA expression in HCC, the corresponding surrounding noncancerous hepatic, and normal liver tissues was 76 6%, 13 3% and 0, respectively. The frequency of MXR7 mRNA expression in HCC without serum AFP elevation and in HCC <5 cm was 9/10 and 5/6 respectively. Conclusions MXR7 mRNA over expression in human HCC is common and MXR7 mRNA may be expressed at early stage of HCC and can serve as tumor biomarker for HCC. The detection of MXR7 mRNA expression in liver puncture tissues may find small HCC without serum AFP elevation in the subclinical stage.
