简介：目的：评价皮肤CT特征对白癜风分期的效果。方法：纳入116例白癜风患者,采用VIDA、皮肤CT特征和临床特征评价其分期,比较各方法的分期效果、灵敏度和特异度。结果：以皮肤CT特征或临床特征进行分期与以VIDA进行分期的结果无明显差异（χ^2值分别为0.66、0.12,P值均〉0.05）;以VIDA分期为标准诊断,皮肤CT特征区分稳定期和进展期的灵敏度为100%,特异度为87.5%;而临床特征区分的灵敏度为97%,特异度为96%,前者灵敏度明显高于后者（χ^2=5.54,P=0.019）,但两组特异度无明显差异（χ^2==1.93,P=0.165）。结论：对于白癜风分期诊断,皮肤CT特征表现出更好的灵敏度,值得临床推广应用。

简介：目的：探讨2μm激光治疗长期口服抗凝药物良性前列腺增生患者的安全性及有效性。方法：对28例长期服用抗凝药物良性前列腺增生患者行经尿道前列腺2μm激光“刀削面”式汽化切除术。结果：手术时间为30～70min，平均时间（45±13）min；术后持续膀胱冲洗1～3d；留置尿管2～6d，膀胱造瘘管于拔出尿管后次日拔出；术后住院时间4～7d。术后随访3～6个月，术前与术后6个月平均IPSS分别为：（22.7±4.5）分、（6.8±3.5）分；QOL分别为：（5.2±0.4）分、（2.2±1.2）分；Qmax分别为：（6.4±1.5）mL／s、（18.8±3.2）mL／s，上述三项指标与术前比较，均有明显改善（P＜0.01）。结论：经过严格术前评估与恰当处理，2μm激光治疗长期口服抗凝药物良性前列腺增生患者安全有效。

简介：基于光学共聚焦原理的皮肤三维计算机断层成像技术（皮肤CT）是近年来新兴的无创性皮肤影像学技术，具有原位、实时、动态等特点，主要应用于皮肤肿瘤、血管性皮肤病及银屑病等常见皮肤病的诊断及鉴别诊断。皮肤CT将光学显微镜技术、激光扫描技术和计算机图像处理技术结合在一起，从而保证可以在细胞生理状态下进行诊断，还可实时动态地对同一组织多次成像，减少了传统切片制作过程中人为因素的影响，在皮肤病学方面的应用越来越广泛，得到了临床医师的一致认可。

简介：目的：探讨经尿道2μm激光前列腺剜除术后短暂性尿失禁最佳治疗方法。方法：对经尿道2微米激光前列腺剜除术后尿失禁患者80例,分成A、B、C、D四组,各20例,分别行观察等待、提肛肌功能训练,中药结合针炙治疗,盆底生物反馈结合提肛肌功能训练治疗,对尿失禁治疗效果分析比较。结果：A组患者术后尿失禁持续天为5~62d（18±2.4）d,B组患者术后尿失禁持续天为4~52d（17±1.8）d,C组患者术后尿失禁持续天为4~17d（9±1.2）d,D组患者术后尿失禁持续天为3~15d（8±0.8）d。结论：经尿道前列腺剜除术后并发尿失禁,中药结合针炙治疗和盆底生物反馈结合提肛肌功能训练治疗效果均较理想,明显优于单纯提肛肌功能训练及观察等待组。
