Short wavelength automated perimetry can detect visual field changes in diabetic patients without retinopathy

Purpose:

The purpose of the following study is to compare short wave automated perimetry (SWAP) versus standard automated perimetry (SAP) for early detection of diabetic retinopathy (DR).

Materials and Methods:

A total of 40 diabetic patients, divided into group I without DR (20 patients = 40 eyes) and group II with mild non-proliferative DR (20 patients = 40 eyes) were included. They were tested with central 24-2 threshold test with both shortwave and SAP to compare sensitivity values and local visual field indices in both of them. A total of 20 healthy age and gender matched subjects were assessed as a control group.

Results:

Control group showed no differences between SWAP and SAP regarding mean deviation (MD), corrected pattern standard deviation (CPSD) or short fluctuations (SF). In group I, MD showed significant more deflection in SWAP (−4.44 ± 2.02 dB) compared to SAP (−0.96 ± 1.81 dB) (P =0.000002). However, CPSD and SF were not different between SWAP and SAP. In group II, MD and SF showed significantly different values in SWAP (−5.75 ± 3.11 dB and 2.0 ± 0.95) compared to SAP (−3.91 ± 2.87 dB and 2.86 ± 1.23) (P =0.01 and 0.006 respectively). There are no differences regarding CPSD between SWAP and SAP. The SWAP technique was significantly more sensitive than SAP in patients without retinopathy (p), but no difference exists between the two techniques in patients with non-proliferative DR.

Conclusion:

The SWAP technique has a higher yield and efficacy to pick up abnormal findings in diabetic patients without overt retinopathy rather than patients with clinical retinopathy.     

人工全髋关节置换术后外侧小切口与标准切口治疗老年股骨颈骨折的临床研究

目的探讨行人工全髋关节置换术后外侧小切口与后外侧标准切口治疗老年股骨颈移位骨折的临床疗效。方法选取2008年7月至2011年6月本院骨外科收治的老年股骨颈骨折患者共88例,随机分为两组,观察组采用后外侧小切口人工全髋关节置换术治疗;对照组行后外侧标准切口人工股骨头置换术治疗。分别比较两种术式的术中失血量、术后恢复情况以及关节功能改良率。结果两组在手术时间、平均出血量、术后下床活动时间方面比较,差异均有统计学意义(P<0.01);两组髋关节功能优良率比较,观察组优于对照组(P<0.05)。结论两种术式均为治疗老年股骨颈骨折患者的有效治疗方法,后外侧小切口术比较安全,且近期疗效优于后外侧标准切口人工全髋关节置换术。     

肾宝合剂质量标准研究

目的:建立肾宝合剂的质量控制方法.方法:采用薄层色谱法对方中所含的淫羊藿、何首乌、黄芪、补骨脂、当归、川芎进行定性鉴别;用高效液相色谱测定方中所含淫羊藿苷的含量.结果:薄层色谱法可鉴别出淫羊藿、何首乌、黄芪、补骨脂、当归川芎,且阴性对照无干扰;淫羊藿苷在0.0466-0.9700μg范围内呈良好线性关系,r=0.9999,平均回收率为99.96％,RSD =0.26％.结论:本方法操作简便、准确可靠,重现性好、可作为肾宝合剂的质量控制方法.     

医学观察数据的元数据框架反标准化应用

目的：构建医学观察数据的语义模型和元数据框架,为医学观察数据的规范化表达和信息共享提供基础.方法：参照国际标准化组织ISO有关信息技术标准及SNOMED CT、LOINC等医学领域相关国际、国家标准,定义医学观察项目的属性和元数据规范,采用UML建模.结果：医学观察数据的语义模型将医学观察逐步分解,形成类的树状层次结构.第一层可分为体格检查、实验室检查等4个子类;类包含一组特定的属性;属性以数据元的形式,通过元数据进行描述;一组特定属性（数据元）的实例即为规范化的医学观察数据.结论：语义模型和元数据框架规范下的医学观察数据具有完整、清晰的语义和统一的格式.构建元数据框架有利于医学观察数据的标准化,可作为国家卫生数据字典的研发策略.     

珍稀濒危药材沉香质量评价方法与市售沉香质量分析研究

沉香作为一种药材在世界许多国家应用,历史悠久。在我国各民族中,沉香除药用外,在饰品、高档香料、家具等应用广泛,影响较大。沉香药材市场价格较高,国家药品标准不够完善,一些不法商人采用高科技手段针对沉香国家药品标准缺陷制假,完全可以符合国家药品标准的各项要求,以假乱真,药材质量得不到保障。亟需新技术、新方法甄别真假沉香。
