丙型肝炎病毒感染对肾移植术后影响的临床研究

OBJECTIVE: To study the influence of hepatitis C virus (HCV) infection on the clinical outcome of kidney transplantation. METHODS: The recipient/graft survival, the incidence of acute/chronic rejection and cause of death in 86 HCV-infected recipients of renal transplantation were compared with those in another 86 recipients without HCV infection. RESULTS: HCV-infected recipients had significantly shorter 5-year survival (74.4%) than those without HCV infection (87.2%, P<0.01). The 1-year (94.2%/90.7% vs 96.8%/96.0%) and 3-year recipient/graft survival rates (88.4%/79.1% vs 90.7%/87.2%), the incidence of acute/chronic rejection (31.3% vs 21.2%, and 12.5% vs 6.5%) and the 5-year graft survival (73.3%/81.4%) were comparable between the two groups (P>0.05). Hepatic disease was identified as the primary cause of mortality. CONCLUSIONS: HCV infection may affect the long-term survival of the recipients with kidney transplantation, and therefore should be considered as a relative contraindication of kidney transplantation.     

贲门失驰缓症介入治疗的疗效评价

目的：评价贲门失弛缓症球囊扩张介入治疗的疗效。方法：对20例贲门失驰缓症患者行球囊扩张术。结果：20例患者共进行了31次球囊扩张，人均1．5次（其中12例扩张1次，5例扩张2次，3例扩张3次）。术后患者吞咽困难明显缓解，主要并发症为疼痛和返流。术后随访无症状期为3－13个月。结论：球囊扩张术是治疗门失弛缓症的有效方法。     

缩窄性心包炎外科治疗72例临床分析

目的 探讨外科手术治疗缩窄性心包炎的经验。方法 对72例缩窄性心包炎病人的外科治疗情况进行总结分析。结果 72例术后1个月心功能I级（59例）、Ⅱ级（11例）。1例术中死于急性心肌膨胀，1例术后死于低心排综合征。结果 心包切除程度、手术时机、手术方法是此类手术成功的关键。     

骨钙素酶免疫检测方法的研究和应用

目的：建立骨钙素酶免疫测定方法，并应用于临床检测血清骨钙素。方法：应用了3种检测模式，根据检测灵敏度、剂量反应曲线的形态进行分析，选择出合适的模式进一步应用于临床血清标本的骨钙素检测。结果：所采用的骨钙素单克隆抗体是钙离子依赖型的。固相抗原竞争法适合于临床定量测定骨钙素。最低可测限为1．4μg/L;20μg/L骨钙素样品批内CV＝3．98％，批间CV＝12．67％。测定正常献血员140名（年龄17－45岁），第5－95百分位点的骨钙素含量，男性为7．5－15．0μg/L女性为7.0-17.5μg/L。70例疑有骨质疏松症患者血清骨钙素含量2．91－30．20μg/L，以第95百分位点的骨钙素含量为cut-off值，升高5例。与进口试剂盒（Novocalcin,USA）相比较，有较好的相关性，r=0.81。结论：固相抗原竞争法酶免疫测定可以灵敏地检测血清中骨钙素含量，有实用价值。     

武汉市人口死亡率季节变动规律的分析

本文运用百分率趋势检验和逐步回归等统计方法,测定和分析了武汉市江岸区居民死亡的季节变动规律。结果表明:月死亡、心血管病和呼吸系病死亡都有明显的冬季高峰,意外死亡多半在夏季;婴幼儿和老年人死亡的季节波动性较大;心脏病、呼吸系病在寒冷月份上升成为第二、第四位死因;逐步回归分析的结果表明:温度是对死亡影响较大的气象因素,肿瘤死亡与季节变化的关系不大。     

Plus disease in retinopathy of prematurity: pilot study of computer-based and expert diagnosis.

PURPOSE: To measure accuracy of plus disease diagnosis by recognized experts in retinopathy of prematurity (ROP), and to conduct a pilot study examining performance of a computer-based image analysis system, Retinal Image multiScale Analysis (RISA). METHODS: Twenty-two ROP experts independently interpreted a set of 34 wide-angle retinal images for presence of plus disease. A reference standard diagnosis based on expert consensus was defined for each image. Images were analyzed by the computer-based system using individual and linear combinations of system parameters for arterioles and venules: integrated curvature (IC), diameter, and tortuosity index (TI). Sensitivity, specificity, and receiver operating characteristic areas under the curve (AUC) for plus disease diagnosis compared with the reference standard were determined for each expert, as well as for the computer-based system. RESULTS: Expert sensitivity ranged from 0.308 to 1.000, specificity ranged from 0.571 to 1.000, and AUC ranged from 0.784 to 1.000. Among individual computer system parameters, venular IC had highest AUC (0.853). Among all computer system parameters, the linear combination of arteriolar IC, arteriolar TI, venular IC, venular diameter, and venular TI had highest AUC (0.967), which was greater than that of 18 (81.8%) of 22 experts. CONCLUSIONS: Accuracy of ROP experts for plus disease diagnosis is imperfect. A computer-based image analysis system has potential to diagnose plus disease with high accuracy. Further research involving RISA system parameter cut-off values from this study are required to fully validate performance of this computer-based system compared with that of human experts.     

沟通艺术在护理管理中的运用

现代管理理念已由单纯管理型向服务型转变。为了能更好地服务于临床护理人员，实现护理的科学管理，管理者必须学会运用有效的沟通技巧与护理人员进行信息及情感交流。[第一段]

慢性肾脏病非透析患者脑钠素与动脉粥样硬化及心功能的关系

目的 研究脑钠素（BNP）与慢性肾脏病（CKD）非透析患者动脉粥样硬化及心功能不全的关系。 方法 采用双抗夹心免疫荧光法检测203例CKD非透析患者与16例高血压患者对照组全血BNP水平，分析其与颈动脉超声结果、心脏彩超结果及既往心血管疾病史的关系。 结果 CKD非透析患者BNP水平与对照组相比显著升高[M（范围）：54.40(15.10～ 173.00) ng/L比9.35(7.35～15.00) ng/L，P < 0.01]。Spearman相关分析显示CKD患者BNP与颈动脉内膜中层厚度（IMT）、左室心肌重量指数（LVMI）等呈正相关。存在颈动脉斑块、左室肥厚或既往发生过心血管事件的患者血BNP水平显著增高。多元回归分析显示LVMI、既往心血管事件均是影响BNP水平的独立因素。 结论 CKD非透析患者BNP水平和动脉粥样硬化性疾病、左室肥厚及心功能不全相关，提示BNP水平可作为一项评价CKD非透析患者心功能及动脉粥样硬化的敏感生物学指标。
