海拔3417m世居及移居者无氧代谢阈与左心功能关系的探讨

在海拔３４１７ｍ对１８名健康世居藏族和１６名移居汉族用Ｊｅａｇｅｒ气体代谢自动分析系统和心阴抗图测定了无氧阈和最大摄氧量时的ＳＶ、ＣＯ、ＰＥＰ／ＬＶＥＴ和ＳａＯ２。结果显示：在海拔３４１７ｍ测得ＡＴ值明显低于海平面；世居藏族ＡＴ出现较晚，并且ＡＴ时的功率、ＶＯ２、ＭＶ、ＨＲ、ＣＯ、ＳＶ均高于移居汉族，而ＰＥＴ／ＬＶＥＴ比值小于移居组；两组的ＳＶ峰值出现时间不同，蕊居组在ＡＴ或ＡＴ以后出现的占７２％     

Structured treatment and teaching of patients with Type 2 diabetes mellitus and impaired cognitive function--the DICOF trial.

BACKGROUND: Patient education is integral part of any diabetes therapy in Germany, but elderly patients are not able to follow the variety of topics comprising standard treatment and teaching programmes (TTP), primarily due to impaired neuropsychological function. This leads to deficits in diabetes knowledge and hindered ability for diabetes self-management. AIM: To evaluate structured TTP for geriatric patients with impaired cognitive function. PATIENTS AND METHODS: A neuropsychological examination was performed on all patients over 54 years [n=102, age 68.6 +/- 8.7 years, diabetes duration 10.3 (0.03-35.4) years, HbA1c 10.3 +/- 1.7% (HPLC, Diamat, NR 4.5-6.3%), cognitive function 87.7 +/- 12.3 IQ points] who took part in TTP for insulin therapy. Patients with impaired cognitive function participated either in the standard TTP of Berger [n = 35, age 67.6 +/- 8.9 years, diabetes duration 9.9 (0.04-35.4) years, HbA1c 10.3 +/- 2.0%] or in the specialized structured geriatric DICOF-TTP [n=33, age 70.4 +/- 8.2 years, diabetes duration 10.4 (0.03-24.9) years, HbA1c 10.7 +/- 1.8%]. RESULTS: After TTP there were no differences in knowledge and ability for diabetes self-management (standard/DICOF: knowledge 11.0 +/- 2.6 vs. 12.2 +/- 2.7 points, P = 0.11; handling 14.9 +/- 3.3 vs. 15.9 +/- 2.5 points, P = 0.18). However, patients who took part in the DICOF programme showed better scores in satisfaction with the education programme [standard/DICOF 44.7 (31-57) vs. 52.5 (45-59) points, P < 0.001]. Six months later the DICOF participants showed better results regarding diabetes self-management (standard/DICOF: handling 12.5 +/- 4.1 vs. 15.9 +/- 3.1 points, P = 0.001). Both groups showed HbA1c decrease (8.3 +/- 1.4 vs. 8.5 +/- 1.3%, P=0.62) and similar incidence of acute complications. CONCLUSIONS: Elderly patients with impaired cognitive function should take part in specialized structured TTP. This leads to both better satisfaction with the education programme and an improved ability for diabetes self-management.

药物敏感试验指导肺癌合并恶性胸腔积液的顺铂联合其他药物胸腔内化疗

目的用药物敏感试验预测肺癌合并恶性胸腔积液癌细胞对顺铂联合其他药物的敏感度，观察其在指导此类患者的顺铂联合其他化疗药物胸腔内化疗的价值。方法将44例胸腔积液癌细胞阳性肺癌患者随机分为两组：药物敏感试验组（20例，有2例因体外药物敏感试验失败而被排除）和对照组（22例）。药物敏感试验组患者用三磷酸腺苷-肿瘤细胞药物敏感试验（ATP-TCA）法分别检测胸腔积液癌细胞对顺铂加香菇多糖、顺铂加甘露聚糖肽、顺铂加A群链球菌制剂、顺铂加干扰素、顺铂加金黄色葡萄球菌滤液制剂、顺铂加卡介苗多糖核酸、顺铂加红色诺卡菌细胞壁骨架、顺铂加白细胞介素-2的敏感度，并选择抑瘤率最高的联合化疗药物对患者进行胸腔内化疗，观察治疗后胸腔积液完全缓解率及胸腔积液癌细胞转阴率，并与对照组比较。结果药物敏感试验组患者对各联合化疗药物敏感的例数为：顺铂加香菇多糖14例、顺铂加甘露聚糖肽18例、顺铂加A群链球菌制剂17例、顺铂加干扰素10例、顺铂加金黄色葡萄球菌滤液制剂16例、顺铂加卡介苗多糖核酸15例、顺铂加红色诺卡菌细胞壁骨架17例、顺铂加白细胞介素-216例。药物敏感试验组完全缓解率为65．0％，对照组为27．3％（P〈0．05）。药物敏感试验组胸腔积液癌细胞转阴率为80．0％，对照组为45．5％（P〈0．05）。结论用药物敏感试验指导肺癌合并恶性胸腔积液的胸腔内个体化化疗可提高完全缓解率和胸腔积液癌细胞转阴率，该方法具有临床实用价值。     

测定血清及尿β2微球蛋白评估健康老年人肾功能的价值

测定72例健康老年人（60-84岁）和65例健康青中年人（20-50岁）血清和尿β2微球蛋白（β2m)，发现前血清β2m浓度比后明显增高（p<0.001)；老年组≥70岁尿液β2m浓度也明显增高（p<0.05)。结果表明肾小球滤过率下降随年龄增长而降低，以后再出现肾小管功能减退。本试验较血清尿素氮、肌酐和内生肌酐清除率测定更为敏感。     

超声心动图房室平面位移法对高血压病早期患者左室舒张功能的评价

目的:探讨超声心动图房室平面位移(AVPD)法评价高血压病早期患者(HT)左室舒张功能的可行性。方法:分别记录200例HT患者左房射血所致AVPD(AVPDa)值、AVPD与二尖瓣环4个位点上的AVPD均值(AVPDmean)比值,并与二尖瓣口E/A比值法(E/A分析法)进行对比。结果:200例HT患者AVPD法测值:AVPDmean值为(0·66±0·15)cm,AVPDa为(0·79±0·46)cm,E/A分析法:E/A最大峰值速度分别为(75·38±11·66)cm/s,(82·36±16·82)cm/s。根据AVPD方法诊断163例舒张功能异常,E/A分析法诊断171例舒张功能异常,二者之间差异无显著性意义(χ2=1·78,P>0·05)。结论:AVPD方法与E/A分析法有较好符合性,为一无创性评价HT患者左室舒张功能的新方法。     

前列腺素E1对尸体肾移植术后肾功能延迟恢复的影响

目的探讨前列腺素E1(PGE1)应用于尸体肾移植术后肾功能延迟恢复(DGF)患者对移植肾功能恢复的影响.方法回顾性分析因急性排斥(AR)和急性肾小管坏死(ANT)导致DGF的127例临床资料,其中应用PGE1治疗56例(PGE1组),未用PGE1者71例(对照组).比较两组在出现DGF后的透析治疗时间、肾功能恢复情况、彩超的移植肾血流阻力指数(RI)及6个月内AR发生率.结果与对照组比较,PGE1组透析治疗时间明显缩短(P＜0.05),移植肾的血肌酐下降速度快(P＜0.05),RI及6个月内AR发生率低(P＜0.05).结论PGE1有利于尸体肾移植术后DGF患者移植肾功能的早期恢复,并能降低AR的发生率.     

Treatment of hepatitis B and C after liver transplantation. Part 2, hepatitis C

Abstract End-stage liver disease caused by the hepatitis C virus is a major indication for liver transplantation. However, recurrence of hepatitis in the graft is a major issue. HCV re-infection after transplantation is almost constant, and recent data confirm that it significantly impairs patient and graft survival. Factors that may influence disease severity and consequent progression of HCV graft injury remain unclear. Chronic HCV infection develops in 60%–80% of patients, and 6%–28% ultimately progress to cirrhosis within 5 years. Pre-transplantation antiviral treatment is not easily related to poor tolerance. Attempts to administer prophylactic post-transplantation antiviral treatment are under evaluation but are limited by antiviral drug side effects. Treatment of established graft lesions with interferon or ribavirin as single agents has been disappointing. Combination therapy gave promising results, with sustained virological response in 25% of patients, but indications, modality and duration of treatment should be assessed.     

肝血管瘤的介入治疗(附32例报告)

目的:总结超选择性动脉栓塞治疗肝血管瘤的经验。方法:对介入治疗的32例肝血管瘤患者进行回顾性分析;同时亦对血管瘤的影像学检查方法进行比较。结果:血管瘤供血动脉超选择性插管操作成功率100%,栓塞后28例见周边碘油呈棉团状沉积,4例显示环状碘油沉积。术前血管瘤最大直径为(8.5±2.3)cm,术后6个月血管瘤最大直径为(6.4±1.8)cm,术后12个月血管瘤最大直径为(4.3±1.8)cm,未出现严重的栓塞综合征反应。各种影像学均能明确血管瘤的诊断,增强CT扫描直观显示血管瘤血液动力学特点。结论:术前增强CT扫描显示的血液动力学特征有助于预期疗效评价,经导管栓塞治疗肝血管瘤疗效稳定,创伤小,复发率及经济费用低。
