模拟定位机引导下经皮穿刺集束巨能刀射频治疗肺癌的临床应用

为了探讨局部麻醉和模拟定位机引导在集束巨能刀治疗肺癌的射频治疗的适应证、治疗效果以及并发症的预防和处理，采用0．5％普鲁卡因局部浸润麻醉，模拟定位机引导下经皮穿刺集束巨能刀治疗肺癌46例。CT显示条索状瘢痕残余ll例，空洞形成或直径缩小32例，无变化1例，增大2例。治疗中患者均有不同程度的胸腔内热感及短时间内可以忍受的疼痛感。并发症包括气胸7例、皮下气肿5例、发热24例、咯血13例和慢性支气管炎急性发作4例。初步研究结果提示，集束巨能刀射频治疗周围型肺癌疗效满意，尤其适用于直径〈3cm的肿瘤。局部麻醉配合全身止痛药物应用可以很好地解决治疗中的疼痛问题，与全麻相比还具有省时省力、费用低的优势；对于周围型肺癌，模拟定位机引导经皮穿刺定位与CT引导相比，同样准确、安全，但操作更为方便。     

两种比色板在前牙修复中效果分析

目的旨在探讨Vitapan Classical比色板和Vitapan3D-Master比色板在口腔修复科临床中的比色效果,以指导临床工作。方法采用修复前比色、修复体制作完成后口腔外比色以及口腔内核对颜色的方法,对比两种比色板的比色效果。结果修复体制作完成后,在口腔内、外核对颜色时,使用Vitapan3D-Master比色板的满意度高于Vitapan Classical比色板(P<0.05)。结论Vitapan3D-Master比色板颜色范围较宽,临床比色可以取得较好的效果。     

两种常用比色板的临床色度学研究

目的从临床角度探讨两种比色板色度学的变化。方法用Shade Eye EX电脑比色仪分别测试Shofu16色比色板和Vita16色比色板的比色片，获得比色片的色调、彩度、明度、色相和瓷粉配方。结果两组比色片的B色调全测为A系列，大多数比色片的色相测为R系列；多数Vita比色片的彩度高于Shofu比色片；两组比色片的明度排列次序不符合Vita 16色比色板的明度排列次序指示，Shofu比色片的明度普遍高于Vita比色片；绝大多数比色片的颜色复制需用偏红色调瓷粉，或需添加偏红色调及红色瓷粉。结论用Shofu 16色比色板或Vita 16色比色板比值和配色，需添加其他系列或特殊颜色的瓷粉。     

CT导向下医疗用臭氧治疗腰椎间盘突出症

目的观察CT导向下医用臭氧治疗腰椎间盘突出症的疗效。方法30例腰椎间盘突出症患者,术前均经CT或MRI检查证实。在CT导向下行臭氧消融治疗。盘内注入浓度为60μg/ml臭氧10-20 ml,退针出纤维环至椎间孔附近,注入浓度为40μg/ml臭氧5 ml。结果随访时间1-6个月,显效7例,有效18例,无效5例,总有效率为80.3%,未发生任何明显并发症。结论CT导向下医用臭氧局部注射是治疗腰椎间盘突出症的一种有效方法。     

The Doppler guide wire: clinical applications in neuroendovascular treatment

The application of Doppler-tipped guide wires to measure blood flow velocity in coronary and peripheral arteries has been described previously as a valuable means of functional assessment in interventional cardiological procedures. In animal studies intravascular Doppler has been used in the cerebrovascular system, and this appears to be an important field of application for this new technique. We used intravascular haemodynamic monitoring by the Doppler guide wire during neuroendovascular procedures in patients with different cerebrovascular diseases and evaluated the clinical feasibility of the method. We found it a safe technique which complements morphological angiographic information with valuable functional data. Further studies may be expected to demonstrate the relation of flow parameters to clinical outcome. Received: 16 January 1996 Accepted: 30 January 1996     

电脑比配色仪与比色板之间的相近性分析

目的：通过对比色记录的分析，比较Vita比色板、松风Vintage Halo比色板和电脑比配色仪之间的相近性和差异性。方法：随机抽取100名年龄在21～24岁的本地在校大学生，由男女两位测试者使用电脑比配色仪、Vita比色板和松风Vintage Halo比色板对被测试者的左上中切牙进行比色分析。结果：三种比色方法均以A色调最为集中，占总数的55％以上。其次是D色调占总数20％以上。男女测试者的选色在A、R、VR．系列中无明显差异。结论：电脑比配色仪、Vita比色板、松风Vintage Halo比色板均不能完全覆盖本地区青年天然中切牙的色度特征，只在A色调系列中重复率较高。

lnter-rater reliability of an oral assessment guide for elderly patients residing in a rehabilitation ward

The aim of this study was to test the inter-rater reliability of a revised oral assessment guide (ROAG) for patients residing in a geriatric rehabilitation ward. A consecutive sample of 140 patients was recruited for the study. Oral assessments were performed for 133 newly admitted patients by one registered nurse (RN) during a period of six months. A dental hygienist (DH) carried out 103 oral assessments during the same half-year. For 66 patients, the RN and the DH performed independent assessments. There was an agreement between the RN and the DH in the majority of the independent assessments, except for tongue and teeth/dentures. The percentage agreement exceeded 80 percent. Inter-rater agreement measured by Cohen's Kappa coefficient ranged from moderate to very good and percentage agreement had a range of 58 to 91 percent. The agreement was highest in assessment of voice and swallowing (91%). Assessments of teeth and dentures seemed to be most difficult for the RN to evaluate. ROAG was found to be a clinically useful assessment tool. Additional education and training is needed to improve the reliability of the oral assessments and should include continuous support from a dental hygienist as well as a pictorial manual on how to use the ROAG.
