Optic chiasm glioma associated with inappropriate secretion of antidiuretic hormone,cerebral ischemia,nonobstructive hydrocephalus and chronic ascites following ventriculoperitoneal shunting

An optic chiasm glioma may cause loss of vision, endocrine disturbances, hydrocephalus and cerebral ischemia due to its proximity to the pituitary, hypothalamus, III ventricle and internal carotids. A 3-month-old infant with optic chiasm glioma developed hypopituitarism and inappropriate secretion of antidiuretic hormone with plasma hypo-osmolality. The cerebrospinal fluid (CSF) protein concentration was markedly elevated. The impairment of fluid absorption via arachnoid villi and peritoneum by the high protein content, and reversed osmotic gradient between protein-rich CSF and hypo-osmolar plasma may have contributed to both nonobstructive hydrocephalus and recurrent ascites following ventriculoperitoneal shunting. Cerebral ischemia from carotid compression may have led to cerebral atrophy.     

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.

同种肾组织移植治疗慢性肾功能衰竭性贫血的实验研究

以Ｗｉｓｔａｒ雄性大鼠为受体，建立慢性肾功能衰竭动物模型，将鼠婴肾组织声多点植入受体双侧后肢皮下和筋膜下。结果表明，３０天后移植物的体积由１ｍｍ＾３增至４ｍｍ＾３大小，表面血管网丰富；光镜下见肾小球、肾小管结构正常。促红细胞生成素（ＥＰＯ）着色颗粒主要分布在肾小球区，移植组着色程度明显增高。血红蛋白和４促红细胞生成素随移植的时间延长而逐渐升高，实验结果提示，此方法有可能为治疗慢性肾功能衰竭性贫血提
