一种胰岛素抵抗的糖尿病特殊类型报告

报告５例对胰岛素抵抗的糖尿病特殊类型病例，其均具有胰岛素应用指征，但使用胰岛素后血糖却反而上升，逐渐增加胰岛素用量，则血糖值亦呈上升趋势。对该类病人的治疗，首先停用胰岛素，改用自制中药制剂及优降糖、降糖灵治疗，取得了良好效果。     

上睑下垂78例手术分析

用额肌悬吊术或提上睑肌缩短术治疗７８例上睑下垂病例，治愈７眼，基本治愈１２眼，矫正不足３眼，矫正过度２眼，笔者认为，术前分析病因；注意提上睑肌肌力的测定；采用适当的手术方法，是手术成功的关键。     

互联网与中医学教育

Influence of blood supply of the esophageal and gastric stumps on anastomotic healing after esophagogastrostomy in rabbits]

OBJECTIVE: To study how blood supply of the esophageal and gastric stumps influences the anastomotic healing after esophagogastrostomy in rabbits. METHODS: Twenty-seven New Zealand rabbits were randomly divided into 3 groups to receive esophagogastrostomy, followed by different procedures. Except for those in group I, all the rabbits were subjected to procedures of reducing the blood supply either of the esophageal or the gastric stump (group II and group III, respectively), followed by single-layer esophagogastric anastomoses using interrupted 5-0 polypropylene sutures. Ten days after operation, all the rats were killed and the anastomotic sites excised for measurement of the inner diameter, tensile strength, and hydroxyproline concentration. RESULTS: Healing of the esophagograstric anastomosis was obtained in all the rabbits but one with anastomotic leakage in group I and one with perforation of the gastric fundus in group III. The anastomotic inner diameters were similar in all the three groups, whereas the tensile strength and hydroxyproline concentration at the anastomoses decreased in group III in comparison with the other two groups (P<0.05) that had similar measurements (P>0.05). CONCLUSIONS: Extended length of the free esophageal stump does not significantly affect anastomotic healing as decrease of blood supply in the gastric stump.     

Comparison of mortality risk associated with bacteremia due to methicillin-resistant and methicillin-susceptible Staphylococcus aureus.

OBJECTIVE: To quantify the clinical impact of methicillin-resistance in Staphylococcus aureus causing infection complicated by bacteremia in adult patients, while controlling for the severity of patients' underlying illnesses. DESIGN: Retrospective cohort study from October 1, 1995, through December 31, 2003. PATIENTS AND SETTING: A total of 438 patients with S. aureus infection complicated by bacteremia from a single Veterans Affairs healthcare system. RESULTS: We found that 193 (44%) of the 438 patients had methicillin-resistant S. aureus (MRSA) infection and 114 (26%) died of causes attributable to S. aureus infection within 90 days after the infection was identified. Patients with MRSA infection had a higher mortality risk, compared with patients with methicillin-susceptible S. aureus (MSSA) infections (relative risk, 1.7 [95% confidence interval, 1.3-2.4]; P<.01), except for patients with pneumonia (relative risk, 0.7 [95% confidence interval, 0.4-1.3]). Patients with MRSA infections were significantly older (P<.01), had more underlying diseases (P=.02), and were more likely to have severe sepsis in response to their infection (P<.01) compared with patients with MSSA bacteremia. Patients who died within 90 days after S. aureus infection was identified were significantly older (P<.01) and more likely to have severe sepsis (P<.01) and pneumonia (P=.01), compared with patients who survived. After adjusting for age as a confounder, comorbidities, and pneumonia as an effect modifier, S. aureus infection-related mortality remained significantly higher in patients with MRSA infection than in those with MSSA infection, among those without pneumonia (hazard ratio, 1.8 [95% confidence interval, 1.2-3.0]); P<.01. CONCLUSIONS: The results of this study suggest that patients with MRSA infections other than pneumonia have a higher mortality risk than patients with MSSA infections other than pneumonia, independent of the severity of patients' underlying illnesses.     

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
