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.

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.

惊恐障碍临床特征及误诊分析

目的 :分析惊恐障碍的临床特征 ,探讨其误诊原因。方法 :回顾性分析惊恐障碍 78例在精神科确诊前的临床资料。结果 :全部多次误诊为躯体疾病 ,尤其易误诊为心血管疾病。误诊时间 1.5～ 5 6个月 ,平均 ( 9.6 5± 13.2 1)个月。结论 :惊恐障碍极易误诊 ,综合医院应提高临床医生对惊恐障碍的认识以减少误诊率。     

去带盲升结肠可控膀胱术后远期并发症(附105例报告)

目的 探讨去带盲升结肠可控膀胱术后远期并发症的发生及防治.方法 回顾性分析1995年10月至2003年1月105例去带盲升结肠可控膀胱术后患者资料.男83例,女22例.年龄32～78岁,平均60岁.随访时间9～82个月,平均40.5个月.结果 发生远期并发症27例（25.7%）,其中导尿插管困难4例（3.8%）,3例行尿道扩张后治愈,1例再次手术利用末段回肠重建输出道;贮尿囊结石5例（4.8%）,4例行贮尿囊切开取石治愈,1例无自觉症状者未行处理;贮尿囊穿孔1例（0.9%）,行手术修补后痊愈;贮尿囊过度扩张1例（0.9%）,行贮尿囊缩小术;肾积水8例（7.6%）,合并输尿管返流1例,合并下段输尿管狭窄4例,其中2例行狭窄段输尿管切除再吻合,1例术前为氮质血症者发展为尿毒症需行规律血透;血氯增高7例（6.7%）,1例出现高氯性酸中毒需长期口服碳酸氢钠;单纯表现为症状性泌尿系感染1例（0.9%）.27例中另合并症状性泌尿系感染10例,根据尿培养结果予敏感抗生素治愈.结论 去带盲升结肠可控膀胱术后远期并发症多与症状性泌尿系感染相关,积极防治泌尿系感染,规律、充分的贮尿囊冲洗及定时清洁导尿对远期并发症的预防有重要作用.     

采用直接血管成形术治疗的急性心肌梗死患者中入院心电图存在左束支、右束支与无束支传导阻滞的预后比较：来自多项急性心肌梗死直接血管成形术试验

急性心肌梗死患者出现束支传导阻滞（BBB）被认为与预后差有关。这种观点在血管成形术时代是否正确尚不清楚。本研究旨在评估采用直接血管成形术治疗的急性心肌梗死伴BBB患者的预后。评估了急性心肌梗死直接血管成形术试验中3053例接受急诊导管术的患者。将入院心电图存在左束支传导阻滞的患者（LBBB，n=48，1．6％）与右束支传导阻滞患者（RBBB，n=95，3．1％）或无BBB患者（n=2910，95．3％）进行比较。具有BBB的患者年龄较大，更多见糖尿病、外周血管疾病和曾行冠状动脉搭桥术，射血分数较低，多支血管病变多见。
