The Relative Contribution of Domains of Quality of Life to Overall Quality of Life for Different Chronic Diseases

This study examined the contribution of the quality of life (QoL) domains physical, social and psychological functioning to the explanation of overall QoL. Various disorders may differentially affect QoL domains due to disease-specific factors and, consequently, the relationship between QoL domains and overall QoL may vary between diseases. We therefore studied this relationship for several diseases as well as the differential impact of these diseases on QoL. The present study had a cross-sectional design. We selected patients (aged 57 years and older) with one of the following eight chronic medical conditions: lung disorder, heart condition, hypertension, diabetes mellitus, back problems, rheumatoid arthritis, migraine, or dermatological disorders. The total group of respondents included 1457 patients and 1851 healthy subjects. Regression analyses showed that the domain of psychological functioning contributed to overall QoL for all disorders, whereas physical and social functioning contributed to overall QoL for some disorders. Differences were found between most patient groups and healthy subjects with respect to physical functioning; with respect to social and psychological functioning some groups differed from the healthy group. Explanations for the findings and implications for clinical practice are discussed.     

美宝湿润烧伤膏在治疗慢性泪囊炎的应用

目的：观察美宝湿润烧伤膏(MEBO)在治疗慢性泪囊炎的应用价值。方法：对87例102只慢性泪囊炎采用泪道探通手术与MEBO置留治疗。常规泪点表面麻醉，扩张泪点，用生理盐水或氯霉素眼水冲洗鼻泪管、泪囊、泪小管，再用无菌注射器装入5ml MEBO，用5号自制泪道冲洗针沿泪道方向插入，直达泪囊推药，使鼻泪管、泪囊、泪小管内充满MEBO，一周后继续上述方法治疗，一般连续治疗2—5次。结果：治疗总有效率为100％，随访6个月，无一例复发。结论：在泪道探通手术后随即留置MEBO治疗慢性泪囊炎，临床效果良好，操作简单方便，经济有效，值得临床推广应用。     

BiPAP ViSION 在慢性阻塞性肺疾病Ⅱ型呼吸衰竭的应用和护理

目的 探讨经鼻(面)罩双水平气道内正压通气(BiPAP)ViSION型呼吸机对慢性阻塞性肺疾病(COPD)伴Ⅱ型呼吸衰竭患者疗效及护理特点。方法 应用BiPAP ViSION型呼吸机对21例COPD伴Ⅱ型呼吸衰竭患者采用鼻/面罩连接单向呼气活瓣行双水平气道正压通气,观察其通气前后动脉血气及临床表现变化。结果 通气治疗后19例患者动脉血氧分压(PaO_2)及氧饱和度(SaO_2)明显升高(P<0.01),二氧化碳分压(PaCO_2)显著降低(P<0.05);肺性脑病症状消失,昏迷患者神志转清。2例病情恶化,其中1例改用有创通气后好转,1例拒绝有创通气死亡。结论BiPAP ViSION呼吸机治疗COPD伴Ⅱ型呼吸衰竭的疗效较为肯定,正确的护理对提高其疗效和减少并发症至关重要。     

肝康胶囊对慢性肝炎的疗效观察

目的 观察肝康胶囊对慢性乙型肝炎的疗效。方法 36例慢性中度肝炎随机分为二组,治疗组给予肝康胶囊口服,每日3次,每次6～8粒,连服1个月为一疗程,根据病情可连服2～3个疗程;对照组给服大黄蛰虫丸,疗程同前。在服药期间定期查肝功能、γ球蛋白、血清透明质酸(HA)、Ⅲ型前胶原(PCⅢ)、Ⅳ型胶原(C-Ⅳ)和层粘蛋白(LN)。结果 治疗组丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)和总胆红素(TB)下降速度明显快于对照组;自觉症状的改善情况也好于对照组;3个疗程后治疗组各项肝纤维化指标以及γ球蛋白均较治疗前显著下降(P<0.01),而对照组变化不甚明显。结论 肝康胶囊对慢性肝炎有良好的抗纤维化和改善肝功能作用。     

青海高原地区501例糖尿病患者慢性并发症调节分析

目的：了解青海高原地区501例住院糖尿病患者慢性并发症的发生情况。方法：调查1996－2000年住院糖尿病患者的一般情况、血糖状态、血压、血脂及慢性并发症的发生情况。并进行统计学处理。结果：高龄、病程长、超体重者发生糖尿病肾病、肾病、神经病变的危险性高；血糖、血脂、血压高者糖尿病肾病、周围神经病变、心脑血管病的发生率高。结论：年龄、病程、肥胖是糖尿病多种慢性并发症的独立或综合危险因素；严格控制血糖、血脂及血压可减少糖尿病慢性并发症的发生发展。     

放免法检测乙型慢性活动性肝炎病人红细胞C3b受体的研究

用放免法检测乙型慢性活动性肝炎病人的红细胞ｃ３ｂ受体（ＫＢＣＣＲ１）．结果：病人ＲＢＣＣＲ１明显低于献血员（Ｐ＜０．０５）；抗－ＨＢｓ特异性免疫复合物阳性病人ＲＢＣＣＲ１明显低于阴性病人（Ｐ＜０．０１），与红细胞Ｃ３ｂ受体花环试验检测结果一致。表明乙型慢性活动性肝炎病人ＲＢＣＣＲ１数量减少，活性下降。其原因可能是特异性循环免疫复合物占据了ＲＢＣＣＲ１空位，使ＣＲ１活性下降。     

Atypical hemolytic uremic syndrome in human immunodeficiency virus-1-infected children

We describe the clinical and pathological findings of the hemolytic uremic syndrome (HUS) in two children with human immunodeficiency virus (HIV) infection. Both patients presented with microangiopathic hemolytic anemia, thrombocytopenia, and subsequently developed renal failure. The diagnosis of HUS was confirmed by renal histopathology in both patients. None of these children presented with bloody diarrhea, evidence of circulating antibody response to Escherichia coli O157 lipopolysaccharide, or other known risk factors for HUS, except for the presence of HIV infection. Each patient was treated with intravenous plasma infusion and renal replacement therapy. Their clinical course was characterized by non-oliguria and lack of significant hypertension throughout the acute phase of the disease. Despite these favorable clinical parameters, both patients developed end-stage renal failure. The etiology of this atypical HUS characterized by poor renal survival remains unknown and the role of HIV infection in its pathogenesis, although possible, is unclear.

Human chronic kidney allograft rejection is accompanied by increased intraglomerular cathepsin B and L activity

Abstract The major reason for late graft losses is chronic rejection. Recently, a large number of studies have indicated that proteolytic enzymes play an important role as mediators of glomerular injury. The cysteine proteinases cathepsins B and L degrade structural matrix proteins such as type I collagen and laminin. We investigated intraglomerular protease activities in 12 patients after kidney graftectomy because of end-tage renal disease following chronic rejection. A group of 12 patients undergoing nephrectomy because of cancer served as controls using only non-involved parts of the kidney. The activities of cathepsins B and L in homogenates of isolated glomeruli were measured fluorometrically methylcoumarylamidc substrates and related to DNA content. In rejected kidney allografts we observed significantly enhanced intraglomerular cathepsin B activity and cathepsin B + L activity.
