Objective To investigate the imaging features of adrenal rest tumor.Methods Twelve patients of adrenal rest tumor proved by surgery or clinical diagnosis were retrospectively analyzed.Among these 12 patients,12 were examined with ultrasound,11 with MR and 1 with CT. MR and CT were performed without and with intravenous injection of contrast material.The imaging features of adrenal rest tumor were retrospectively summarized and the relevant literatures reviewed. Results The adrenal rest tumors were found in testis in 10 of the 12 patients,and in ovaries and broad ligament in the remaining two.The imaging features of the testicular adrenal rest tumor were summarized as following:all patients had bilateral testicular masses without change of the testicular contour. On ultrasonography,the lesions were hypoechoic, with some hyperechoic areas and appeared highly vascularized on Colour Doppler ultrasonography.The masses showed iso-density on plain CT,and avid enhancement on post-contrast CT images.The masses ranging in size from0.7 cm×1.0 cm×2.2 cm to 2.3 cm ×2.7 cm ×2.9 cm with uniform signal intensity,lobulated margin on MRI.They exhibited iso- or slight hyperintensity on T1 WI and hypointensity on T2WI relative to normal testicular parenchyma.The tumors showed intense enhancement on post-contrast MR images. No abnormality was detected with Colour Doppler uhrasonography and MR in 2 patients of adrenal rest tumor in ovaries and broad ligament. Conclusion Combining imaging features with the typical clinical history,the diagnosis of adrenal rest tumor could be suggested pre-operatively.

OBJECTIVETo discuss the changes in Wnt pathway inhibiting factors in esophageal precancerosis lesions induced by methyl benzyl nitrosamine (MBNA) and the effect of Gexia Zhuyu decoction.
METHODWistar rats were subcutaneously injected with MBNA (3.5 mg x kg(-1) for twice per week to establish the model. Since the 1st day after the model establishment, they were orally administered with Gexia Zhuyu decoction (16, 8 mg x kg(-1)). At the 10th week, esophageal tissues were collected to observe the pathological changes of esophageal mucosa, detect SFRP1, sFRP4, Axin1, Axin2 and GSK-3β mRNA levels.by fluorescent quantitation PCR analysis and β-catenin protein level by Western blotting.
RESULTBeing induced by MBNA, rats in the model group showed slight atypical hyperplasia in the histopathological examination. Compared with the normal group, Gexia Zhuyu decoction dose high and low groups showed no significant pathomorphological and histological changes. The model group showed lower gene transcription levels of esophageal tissues sFRP1, sFRP4, Axin1 and Axin2 (P < 0.05 or P < 0.01) and higher β-catenin protein expression level (P < 0.01) than the normal control group. The Gexia Zhuyu decoction low dose group showed higher gene transcription levels of esophageal tissues sFRP1, sFRP4, Axin1 and Axin2 (P < 0.05 or P < 0.01) and lower β-catenin protein expression level (P < 0.01) than the normal control group.
CONCLUSIONUp-regulated β-catenin protein level and down-regulated Wnt pathway could enhance Wnt pathway activity of MBNA-induced esophageal precancerous lesions. Gexia Zhuyu decoction could down-regulate the β-catenin protein level and up-regulate the transcription level of Wnt pathway inhibiting factors, but could not block MBNA-induced esophageal precancerosis lesions.
