Abstract］ objective to evaluate the distinctive clinical value of magnetic resonance urographymru）in the diagnosis of primary ureteral carcinoma.methods to compare the accuracy of diagnosis of mru with ultrasonography,urography,retrograde ureteropyelography and ct,diagnostic imaging and progress of ureteral carcinoma were analyzed in twenty-four cases from 2000 to 2006,twenty cases had mru examinations.the original preoperative diagnostic reports of various imaging facilities were analyzed on account of the results of operation and pathology.results mru could clearly show the obstructive location of ureter.with regard to the ureteral carcinoma,accuracy of the location diagnosis was 100%.mru was superior to ulstrasonography,kub+ivp,ureteropyelography and ct we used to apply.conclusion comparing with other diagnostic imaging facilities,it has an important value in highly efficient,accurate location,safe,noninvasive and so on with mru,which can be used to show the features of primary ureteral carcinoma and has a wider scope of clinical application.

目的 探讨磁共振水成像技术在原发性输尿管肿瘤中的临床诊断价值。方法分析2000～2006年24例原发性输尿管肿瘤的影像学诊断结果，并基于术中所见和病理报告，将磁共振水成像技术20例）与超声24例）、泌尿系造影24例）、逆行造影15例）、ct(19例）的确诊率相比较。结果 mru能清晰显示输尿管的梗阻部位，定位诊断准确率为100%，梗阻病因确诊率高于b超、泌尿系造影、逆行造影和ct检查。结论与其他影像诊断方法相比较，磁共振水成像在显示原发性输尿管肿瘤特征方面具有效率高、定位准确和安全无创等重要价值，而且有更广泛的临床应用范围。

To determine the effects of ovarian steroid hormones and some cytokines on the expression of RANTES in cultured cells METHODS AND RESULTS The study included the following two parts 1 The Protein Production of RANTES in Peritoneal Fluids and the Expression of RANTES mRNA in Eutopic and Ectopic Endometrium of Patients with Endometriosis Twenty-eight patients with endometriosis were selected as study group and twenty patients without endometriosis and maglinant disease were selected as control group . In our study, 10 samples of peritoneal fluid in Em and 10 samples of in En were taken, 13 specimens of ovarian endometrioma , 3 red peritoneal endometriotic lesions , 2 uterosacral ligament nodules , 17 matched eutopic endometrium and 12 specimens of endometrium in En were biopsied.

研究目的 1 从蛋白水平检测RANTES在子宫内膜异位症患者腹水中的表达，从核酸水平比较RANTES在内异症患者的异位病灶和在位内膜与非内异症患者子宫内膜之间表达的差异，探讨RANTES在内异症患者盆腔炎性反应中的作用；2 体外培养在位和异位的子宫内膜细胞，研究细胞因子TNFα、INFγ、雌孕激素以及PPARγ激动剂15-d-PGJ〓对RANTES表达的影响，探讨这些因素在内异症发病机理及内异症患者盆腔炎性反应中的作用。
