12例Dandy—Walker综合征的临床CT与MRI分析

目的分析Dandy—Walker综合征的临床及cT与MR!影像特征。方法采用cT与MRI常规扫描，对12例Dandy—Walker综合征的临床表现、CT与MRI征象进行回顾性分析；结果12例Dandy—Walker综合征的CT与MRI表现归纳为①小脑蚓部缺失，小脑半球发育不良、完全分离，分离的小脑半球可以不对称；②第四脑室呈囊状、扇形、三角形显著扩张或后颅窝巨大囊状阴影与第四脑室相通；③窦汇异常抬高，越过人字缝／天幕抬高；④幕上脑室对称性扩张，脑积水。结论对Dandy—Walker综合征的诊断，CT扫描能够显示后颅凹及天幕上下脑的形态与结构，其CT表现具特征性；MRI可多平面扫描，无骨质伪影，显示后颅凹优于CT，在矢状面上可显示小脑、第四脑室、导水管、后颅凹囊肿以及与天幕的关系。CT与MRI扫描对Dandy—Walker综合征能够做出定性诊断，是术前诊断的主要依据，检查无痛苦，有重要的诊断和鉴别诊断价值。

肾综合征出血热地鼠肾细胞Ⅱ型灭活疫苗的安全性、免疫性及其流行病学效果考核

目的：考核HFRS地鼠肾细胞Ⅱ型灭活疫苗的安全性、免疫法及其流行病学效果。方法：采用间接免疫荧光抗体试验（IFA）、微量细胞变性中和试验（MCPENT），检测接种者血中荧光抗体及中和抗体水平；调查接种组与对照组发病情况。结果：以怀宁、广德两县18个村为疫苗观察现场，接种组7499人，对照组7261人，中强反应率为224％（5／223）。3针全程免疫后中和抗体阳转率为63．33％（19／30），荧光抗体阳转率为38.58％（27／70）；接种后1年内接种组无发病，对照组发病3例。结论：该疫苗的安全性较好；有一定水平的免疫应答，但防病效果应进一步观察确证。     

Congenital cardiac malformations in Adams-Oliver syndrome

Whole genomic hprt clones were used in Southern analysis to screen the integrity of the hprt gene in a family that includes a patient with HPRT enzyme deficiency causal to Lesch-Nyhan syndrome. A 5 kb DNA sequence deletion was found to have its endpoints in the first and third introns. The probes identified the carrier status of female family members, aided by an RFLP carried by the mother's normal X-chromosome.     

蝮蛇抗栓酶与肝素抗凝治疗小儿肾病的疗效比较

本文对60例小儿肾病患儿随机分为3组,蝮蛇抗栓酶治疗组,肝素治疗组,常规治疗组(对照组),结果总有效率分别为95％,90％,60％。蝮蛇抗栓酶组与对照组比较,差异有极显著性(P<0.01),肝素组与对照组比较,差异有显著性(P<0.05)。结果提示抗凝治疗对小儿肾病高凝状态有明显改善作用,能增加临床疗效。蝮蛇抗栓酶抗凝效果优于肝素。

不同剂量辛伐他汀对肾病综合征高脂血症的近期疗效

目的 :观察辛伐地他汀 -舒降之对肾病综合征高脂血症的近期疗效及安全性 ,比较不同剂量辛伐他汀的降脂作用。方法 :72例均系肾综合并高脂血症的患者 ,随机分治疗组 (5 6例 )和对照组 (16例 ) ,在积极治疗原发病的同时 ,治疗组给予服辛伐他汀每晚 5～ 2 0mg ,14例混合性高脂血症患者同时服用非诺贝特 ;对照组未用降脂药。观察治疗前及治疗后 1周、2周血脂全套 (TC ,TG ,LDL和HDL)、肝功能 (AST ,ALT ,TP和ALB)、肾功能 (BUN ,Scr)、及尿蛋白定量的变化。结果 :辛伐他汀每晚 2 0mg服用 1周可使 6 3%的患者总胆固醇 (TC)下降 33% ,服用 2周可使 84%的患者血TC降至正常 ;单用辛伐他汀在降低TC的同时 ,可使甘油三酯 (TC)下降 43.16 % ,若与非诺贝特合用可使TG下降达 6 4.2 2 % ,未见不良反应发生 ;辛伐他汀的降脂作用与剂量及用药时间密切相关 ,2 0mg >10mg >5mg ,每晚服用 5mg共 2周仅能使 6 0 %的患者TC下降 12 .5 %。结论 :辛伐他汀 (每晚 2 0mg)能安全、快速有效降低肾病综合征患者的高脂血症 ,而对减少尿蛋白、改善肾功能近期无作用     

Matching blood donations to type-specific product needs: A recruitment technique

The conversion of multiple whole blood donors to apheresis donors is a challenge since a rapidly expanding apheresis donor base could erode homologous collections. We addressed this concern with a plan to enhance apheresis recruitment as well as donations among homologous donors with types O and B blood. Focusing the donor's attention on blood type as it relates to type-specific product needs was the basis of our approach. A matrix was used to recruit the desired types for the desired procedures (whole blood, platelet/plasma apheresis). The matrix instructed donors of blood types O, A-, and B- to primarily give whole blood and to give apheresis as a secondary donation. Donors AB, A+, and B+ were primarily directed to apheresis donations, whole blood donation being secondary. A+ and O- donors only gave their secondary donation if they were at maximum donations with the primary donation. The collections by blood type in percentages for 12 months of 1992/93 for whole blood were O+ 38.9, 0- 7.3, A+ 29.5, A- 5.7, B+ 11.9, B- 2.1, AB+ 3.7, AB+ 0.7. For apheresis it was 0+ 36.2, 0- 6.7, A+ 33.0, A- 6.6, B+ 10.4, B- 1.2, AB+ 4.9, AB+ 1.0. In 1992/93, A+ and B+ apheresis collections as compared to total apheresis collections increased by 4.9% and 13.7%, respectively. For O group apheresis donations, a decrease of 2.5% was shown and A+ whole blood donations decreased by 5.35%. During the same period of time, total apheresis collections increased by 3,058 units. We demonstrated that integration of apheresis recruitment with type-specific whole blood recruitment yielded significant increases of type-specific products.     

激素敏感型肾病单个核细胞培养上清液对大鼠肾小球多阴离子及超微结构的影响

用刀豆蛋白Ａ刺激激素敏感型肾病单个核细胞，并将其培养上清液灌注于大鼠肾内。结合电镜观察，用图像分析仪及体视学方法分别对其肾组织胶体铁染色切片和电镜照片上的足突和滤过裂隙的平均宽度进行测定。结果表明：该病极期上清液灌注的鼠肾小球多阴离子明显减少，足突肿胀、融合，滤过裂隙变窄；而该病缓解组和正常对照组则为阴性。说明该病单个核细胞培养上清液可引起鼠肾小球微小病变型肾病综合征的病变，并揭示该变化可能是由其上清液中一种异常的Ｔ淋巴细胞因子所致。
