目的应用彩色多普勒超声（CDFI）观察2型糖尿病（T2DM）患者各级肾内动脉血流动力学指标参数的改变,以期寻找更早期的、无创性的糖尿病肾病（DN）辅助诊断方法。方法选择30例T2DM患者,排除合并心衰、泌尿系感染、结石、肾血管疾病及其他原因致肾脏原发、继发病变,所有患者尿蛋白阴性,血尿素氮、肌酐正常。同时选择28例健康者作为对照组。应用彩色多普勒超声诊断仪检查受试者各级肾内动脉血流动力学参数。结果T2DM组各级肾内动脉阻力指数（RI）较对照组明显增高,舒张末期最低流速（Vd）则明显减低,均与正常对照组差异有显著性（P〈0．05）。结论彩色多普勒超声检测能提示T2DM患者肾血流动力学改变情况,对早期DN的诊断是有价值的。     

亚临床型精索静脉曲张的超声诊断及精液质量分析

Objective To explore the diagnostic value of color doppler flow imaging (CDFI) on subclinical varicocele(SVC) and the weakening effect of SVC on male fertility.Methods Thirty patients with SVC were exam-ined by CDFI, the diameter and regurgitation duration of spermatic vein were recorded.All semen specimens were rou-tinely analyzed according to the WHO criteria for sperm morphology.Thirty healthy sperm donors were served as con-trols.Results CDFI displayed a widened diameter( 1.94±0.28 mm vs 1.36 ±0.15 mm, P < 0.05 ) and prolonged regurgitation duration[(1.33 ±0.22)s vs(0.43 ±0.16)]s,P<0.05)of spermatic vein in patients with SVC.Sperm density[(20.2±0.1)106/ml vs(86.3±0.6)]106/ml,motihty[(50.7±0.9)% vs(78.5±3.6)]% and vitality [(41.5 ±0.3)% vs (58.7 ±0.6)]% were significantly decreased in patients with SVC compared with those in con-trols (all P< 0.05) ,while the rate of teratospermia remarkably increased in SVC group[(10.5±0.2)vs(4.8±1.7 )]%(P< 0.05 ).Conclusion CDFI was clinically valuable for diagnosis of SVC for its revealing morphological and hemodynamic changes of varicocele.When combined with semen quality analysis,which evaluates the weakening effect of SVC on male fertility, CDFI was suitable to provide the appropriate clinical approaches for SVC therapy.     

超声及彩色多普勒对膀胱占位病变的诊断意义

目的:探讨超声检查对膀胱占位病变的诊断意义。方法:对85例经膀胱镜、手术及病理证实的膀胱占位性病变进行声像图和彩色多普勒显像分析,并与病理结果对照。结果:超声能显示病灶的大小、形态、位置及附着部对膀胱壁有否浸润;彩色多普勒血流分布形态在不同性质占位病变具有差异性;恶性肿瘤血流阻力指数较良性肿瘤明显升高(0.63±0.08vs0.41±0.03,P<0.01)。结论:超声及彩色多普勒对膀胱占位病变的诊断及鉴别诊断具有一定临床应用价值。
