Cosmetic benefits of lower midline skin incision for pediatric open heart operation

OBJECTIVE: Since we developed the procedure in 1996, we have now performed 100 pediatric open heart operations using a lower midline skin incision and a minimal sternotomy approach. METHODS AND RESULTS: To elucidate the benefits of this approach, we analyzed these 100 cases retrospectively. There was no death, and no major complication, caused by this approach, and the resulting scarring in each patient is difficult to be seen under a common undershirt. CONCLUSION: This review shows that the technique of a lower midline skin incision and minimal sternotomy approach is a safe reliable and cosmetically advantageous method for a pediatric cardiac operation.     

脑血管血液动力学参数脑卒中预测模型的建立

目的 根据脑血管血液动力学参数(CVHI)和脑卒中的主要危险因素建立脑卒中预测模型。方法 选择全国六大行政区脑卒中研究队列人群25355例，将基线调查时的CVHI检测结果 进行主成分分析，再以各主成分和主要脑卒中危险因素为自变量，以随访中脑卒中发病为应变量进行回归分析，根据回归系数建立脑卒中预测模型，计算发病概率，绘制ROC曲线，确定最佳截断点，评价预测模型的预测效能。结果 四个主成分的累积贡献率依次为58．1％、79．4％、88．4％和94．6％，被筛检进入logistic回归方程的变量分别为第一至第四主成分、高血压病史、年龄和性别，ROC曲线下面积为0．855，最佳截断点为预测概率≥0．05，预测脑卒中的敏感度、特异度和准确度分别为踟．7％，78．5％，78．5％。结论 通过主成分回归分析，可以建立具有良好效能的脑卒中预测模型。     

Olfaction in essential tremor patients with and without isolated rest tremor.

An olfactory deficit is present in patients with essential tremor (ET), but it is often milder than that in patients with Parkinson's disease (PD). In both, the deficit occurs early in the disease. Isolated rest tremor without other signs of parkinsonism can occur in patients with ET. If the rest tremor in these patients represents a manifestation of ET rather than early PD, we hypothesized that their University of Pennsylvania Smell Identification Test (UPSIT) scores would be similar to those of ET patients without rest tremor. The mean UPSIT score in 13 ET patients with isolated rest tremor did not differ from that of 58 ET patients without rest tremor (29.3 +/- 4.3 vs. 29.4 +/- 6.4; P = 0.69). Several ET patients with rest tremor had UPSIT scores that fell outside of the range that is seen in 95% of patients with PD. These data raise the possibility that some ET patients with isolated rest tremor may not have early PD and that the pathological process that is responsible for their ET is also involving the basal ganglia.

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     

冠心病中医辨证与载脂蛋白关系的初步研究

对９６例各种类型冠心病患者进行中医辨证分型，检测其血清载脂蛋白ＡⅠ及Ｂ１００（ａｐｏＡⅠ及ａｐｏＢ１００），并设立对照组。结果显示各证型冠心病患者的ａｐｏＡⅠ，ａｐｏＢ１００及ａｐｏＢ１／ａｐｏＡⅠ均有不同程度的改变。在标实证中以痰浊型改变最为明显，其ａｐｏＡⅠ显著降低，ａｐｏＢ１００及ａｐｏＢ１００／ａｐｏＡⅠ显著升高。在本虚证型中以肾虚型改变最为明显、其ａｐｏＡⅠ显著降低。ａｐｏＢ１００／ａｐｏＡⅠ显著升高。这种各证型间的差异无疑对冠心病的中医辨证客观化有一定意义，值得进一步验证和探讨。     

DTPA renal scan assessment of renal allograft dysfunction in rats

The precise cause of allograft dysfunction after renal transplantation often cannot be established by non-invasive means. In clinical practice, radionuclide scans form an integral part of the clinician's armamentarium in the assessment of these patients [1, 2]. Unfortunately, in the clinical setting more than one pathological process may be responsible for the impaired function, making it difficult to correlate the scan appearances with the pathology. In this study in rats we compared the renal DTPA scan appearances of the various pathological processes which may cause renal allograft dysfunction in the immediate post-transplant period.     

烟雾病11例临床分析

自１９８５年至今，我院收治１１例经脑血管造影诊断的烟雾病患者。按照日本厚生省本病诊断标准，９例为确诊病例，表现为双侧颈内动脉末端、前动脉、中动脉起始部狭窄或闭塞，其中６例在双侧颅底可见烟雾状异常血管网，３例见单侧血管网；２例为可疑病例，仪表现为单侧上述异常改变。强调应严格烟雾病的诊断。本组采用颞浅动脉一硬膜脑贴敷术治疗患者１例，效果良好，结合日本该病治疗现状讨论，间接血行再建方法仍不失为烟雾病患者的合理治疗方法。     

Large French-Canadian family with Lewy body parkinsonism: exclusion of known loci.

The identification of rare, large families with Parkinson's disease (PD) has provided important clues that have contributed to our understanding of this complex disorder. We have identified a large French-Canadian kindred that spans five generations consisting of more than 90 individuals. A total of 65 individuals now have been examined, had venous blood drawn, and DNA extracted. Two-point and multipoint linkage analysis was performed to assess linkage to known PD genes or loci. Within the third and fourth generations of this family there are 10 living, plus 3 deceased members with well-documented levodopa responsive parkinsonism. Autopsy results on 1 member demonstrated the loss of pigmented neurons in the substantia nigra and the presence of alpha-synuclein positive Lewy bodies. Four of the PD patients have prominent postural and kinetic tremors that preceded their parkinsonism by up to 10 years. Two other individuals within the family have prominent isolated postural and kinetic tremors without parkinsonism. The alpha-synuclein(4q21.3-23), Parkin(6q25.2-27), PARK3 (2p13), PARK4, and ubiquitin carboxy terminal hydrolase-L1 (4p14-16.3) and PARK6 and PARK7 (1p35-36) loci were excluded in this kindred using closely linked markers. The clinical and pathological features of this family are consistent with the diagnosis of PD. This family further demonstrates the known genetic heterogeneity in PD and is large enough that a genome-wide screen has been undertaken in an effort to identify a novel PD gene.
