Application of UF100 Full-auto Urine Sediment Analyzer in Detecting Cylindruria

【摘要】 目的 探讨全自动尿沉渣分析仪在尿管型检测中的应用。 方法 收集尿管型患者晨尿标本836份。所有标本均经尿干化学分析仪检测Pro≥1+或尿沉渣分析仪提示有管型。采用UF100全自动尿沉渣分析仪和显微镜检测管型，对比分析两者的检测结果。 结果 836份标本中，UF100全自动尿沉渣分析仪检测阳性者320例，占38.28%；显微镜检测阳性者195例，占23.33%。其中UF100全自动尿沉渣分析仪的假阳性率为26.52%，假阴性率为23.08%。UF100尿沉渣分析仪与显微镜检测管型的阳性结果比较，差异有统计学意义（Plt;0.01）。 结论 UF100全自动尿沉渣仪能快速筛检尿沉渣，但存在一定的假阴性，必须同时将其检测结果与尿干化学结果结合考虑以决定是否再进行显微镜检测，减少假阴性以防止漏检。【Abstract】 Objective To investigate the application of UF-100 full-auto urine sediment analyzer in detecting cylindruia. Methods 836 specimens with cylindruia were selected. All the specimens with Pro≥1+ were dectected by chemical dipstick or cylindruia by urine sediment analyzer. The cast were detected by urine sediment analyzer and microscope, and the results were compared. Results Of 836 specimens, 320 positive samples(38.28%) were found by UF-100 while 195 (23.33%) were found by microscope. False positive rate and false negative rate of UF100 were 26.52% and 23.08%. Compared the results of urine sediment analyzer with microscope, the difference was statistically significant (Plt;0.01). Conclusions UF100 can detect urinary cast quickly, but there is a little high false negative rate. So we should consider urine sample whether to be detected by microscope compared with results of UF100 and chemical dipstick.

中药治疗消化性溃疡疗效观察

摘要:目的: 观察自拟中药胃病I号方治疗消化性溃疡的疗效。 方法 :采用随机数字将90例消化性溃疡患者分为两组,治疗组60例,采用自拟中药胃病I号方治疗;对照组30例,采用奥美拉唑、阿莫西林、克拉霉素治疗。观察两组治疗前后证候疗效、胃镜疗效、临床症状改善情况及幽门螺杆菌(Hp)的根除率。 结果 :治疗组证候总有效率与对照组比较差异有统计学意义(〖WTBX〗P lt;0.05),治疗组证候疗效优于对照组,治疗组胃镜总有效率、Hp根除率分别与对照组比较差异无统计学意义(〖WTBX〗P gt;0.05),治疗组疗效与对照组相当。治疗组在改善上腹疼痛方面与对照组疗效相当,但在改善食欲不振、返酸、嗳气方面,治疗组疗效优于对照组。 结论 :自拟中药胃病I号方治疗消化性溃疡疗效肯定,副反应少,值得推广。

A study on the short-term fluctuation of macular light threshold in suspected early age-related macular dege-neration

Objective To study the significance of detection the short-term fluctuation (SF) of macular light threshold detected by Octopus-123 automatic perimeter in suspected early age-related macular dege-neration (AMD). Methods SF of macular light sensitivity, Amsler chart and central visual acuity were examined in 51 patients(66 eyes) with suspected early AMD group and in 32 patients (40 eyes) in the control group. Results SF were significantly different in suspected early AMD group and control group. SF was more sensitive than the examination of central visual acuity and Amsler chart. SF was related to the quantity, location and quality of drusen. Conclusion Visual function of some suspected early AMD patients with drusen may be damaged, though the central visual acuity appears normal. (Chin J Ocul Fundus Dis, 2002, 18: 119-120)

蓝黄色视野检查在老年性黄斑变性中的应用

　　蓝黄色视野检查(B/YP)又称短波视野检查(SWAP)，是一种将色觉与视野检查结合形成的新视野检查方法，与常规视野检查结果有较好的一致性，而且检查出的缺损面积更大，缺损深度更深，对视野缺损的检出更为敏感，可以比传统方法更早检测出老年性黄斑变性（AMD）的视野丢失，是一种快速、非侵入性且易于被AMD患者掌握的检测方法，能为临床早期发现、诊断及治疗AMD提供较可靠的依据。

Clinical Value of CT-guided Transthoracic Core Needle Biopsy in Diagnosis of Solitary Pulmonary Small Nodule Lesions

目的：评价CT引导下经皮穿刺活检肺内小结节病灶的诊断价值。方法：在CT导向下穿刺活检肺内直径≤2 cm的孤立性的小结节病灶51例，作细胞学和组织学的检查。结果:本组51例共行58次穿刺活检，24例获得细胞学涂片检查，39例获得组织学检查。诊断准确率82.3%（42/51）。并发症主要为肺出血和气胸，其发生率分别为21.6%（11/51）和13.7%（7/51）。结论：CT导向下穿刺活检肺内小结节病灶的诊断确诊率高，并发症轻。可作为一种常规检查手段。

Clinical characteristics and features of images of optical coherence tomography in vitreomacular traction syndrome

ObjectiveTo observe the characteristics of the images of optical coherence tomography (OCT) performed on the patients with vitreomacular traction syndrome and its clinical significance.MethodsThe clinical data of 25 patients with vitreomacular traction syndrome diagnosed by OCT, fundus fluorescein angiography, and B-scan ultrasonography and confirmed by surgical treatment were retrospectively analyzed. The features of images of OCT in vitreomacular traction syndrome were observed.ResultsFive types were found in the images of OCT in the patients with vetreomacular traction syndrome. The main characteristic of the images of OCT in the patients with vitreomacular traction was the highly reflective band of the vitreous posterior cortex inservion at fovea. In 25 patients, vitreomacular traction associated with macular edema was found in 10, macular hole in 3, macular epiretinal membrane in 6, retinoschisis in 1, and retinal detachment in 5.ConclusionOCT is a potential powerful toll for detecting and monitoring vitreomacular traction syndrome. (Chin J Ocul Fundus Dis, 2005,21:86-89)

A histological observation on the retinas from neonatal mice of different day-ages

Objective To study the progressive development of the retinas through an observation on the histological changes of the retinas from neonatal mice of different day-ages. Methods The retinas from the mice of 1 to 20 days of age were examined by light microscopy,and from 1 to 3 days,by autoradiography. Results The retinas of the mice below 3 days of age only had the RPE cells layer,the neuroblast layer and the ganglion cell layer.With the increase in dayage,the retinas developed gradually and would be mature in the 20th day. Conclusions The retinas of mice is a kind of immature tissue before the 20th days,so it can be considered as transplantation donors. (Chin J Ocul Fundus Dis, 1999, 15: 174-176)
