整体护理改善护患关系的体会

整体护理的实施,重塑了护士的职业价值观,增加了护患之间的接触。护士能够在自己的专业范围内积极主动地解决病人的问题,挖掘了护理人员的自身潜力,加深了护患交流,使护患关系明显改善。     

ENDOSCOPIC PANCREATIC STENTING IN CHRONIC PANCREATITIS WITH DUCTAL DILATION PROXIMAL TO A STRICTURE: A SAFE and EFFECTIVE PROTOCOL

After removal of intraductal stones, a 10‐Fr or 7‐Fr pancreatic stent was placed in 16 patients with upstream ductal dilation proximal to a stricture of the main pancreatic duct. Stents were removed after a mean duration of 52.5 days. Nine patients underwent repeated stenting. About one year after removal of the initial stent, when the remaining upstream ductal dilation was found on follow‐up pancreatograms, the next stent was replaced. Repeated stenting improved outflow of pancreatic juice more effectively than one‐time stenting. Correlation between long‐term pain relief without recurrence of intraductal stones and reduction of duct diameter was also shown. Stent occlusion was observed in 14 of 30 stents. Stent occlusion was frequently associated with recurrence of pancreatitis and intraductal stones, and was also associated with morphologic changes in the pancreatic ductal system. Although there were no significant differences between stent patency of the initial stents and that of the next stents, stent patency of 10‐Fr stents was superior to that of 7‐Fr stents. 10‐Fr stents should be removed within 8 weeks and 7‐Fr stents should be removed within 4 weeks for the prevention of stent occlusion. Repeated stenting with short‐term stenting is therefore considered a safe and effective protocol of endoscopic pancreatic stenting.     

中西医结合疗法延缓慢性肾功能不全患者急性肾功能减退的临床研究

目的:探讨中医活血化瘀结合西医疗法是否具有延缓慢性肾功能不全患者急性肾功能减退的疗效.方法:回顾性分析未行透析的慢性肾功能不全患者32例,近期肾功能急性进行性减退,血尿素氮(blood urea nitrogen,BUN)、肌酐(serum creatinine,SCr)进行性升高.常规治疗基础上,均予以中药保留灌肠30 min,同时加静脉滴注活血化瘀等中西药物治疗14 d.观察治疗前后患者血常规、电解质、肝肾功能以及内生肌酐清除率(creatinine clearance rate,Ccr)的变化.结果:治疗后患者血常规、电解质无明显改变,大多数患者BUN和SCr较治疗前下降,而Ccr升高,总有效率达65.6%.结论:中西医结合疗法可有效逆转慢性肾功能不全患者伴发急性肾功能减退时肾功能的恶化.     

适应性反应对中医药研究的启示

适应性反应是近年医学研究的热点问题之一,利用适应性反应已作为疾病防治的新战略,其核心和精髓是充分调动和激发机体内源性保护机制,增加机体适应性和抗损伤能力,维持机体自稳态.适应性反应的研究表明了机体自身存在着很强的内源性保护机制,其本质是适应性反应诱导了内源性保护物质(保护性蛋白等)的产生,而用药物等途径则可模拟或增强适应性保护作用.适应性反应与中医学的天人相应、正气学说、扶正固本、藏象学说、治未病思想、适应原中药、针灸经络等理论有诸多联系,对中医药研究有一定的启示,对于揭示中医学的科学内涵和实质、发展和弘扬中医理论及促进中西医结合均具有一定参考意义.     

Singularities explained: Response to Klein.

Klein [Klein, A. S. (2006). Separating transducer nonlinearities and multiplicative noise in contrast discrimination. Vision Research, 46, 4279-4293] questions the existence of intrinsic singularities in two-alternative force-choice (2AFC) Signal Detection Theory (SDT) models, suggesting that the singularities found in Katkov et al. [Katkov, M., Tsodyks, M., & Sagi, D. (2006a). Singularities in the inverse modeling of 2AFC contrast discrimination data. Vision Research, 46, 259-266; Katkov, M., Tsodyks, M., & Sagi, D. (2006b). Analysis of two-alternative force-choice Signal Detection Theory model. Journal of Mathematical Psychology, 50, 411-420] are due to discarding higher order terms in the Taylor expansion of d' and/or limited to steep psychometric functions. Here we provide some simple intuitive examples that illustrate the results described in Katkov et al. (2006a, 2006b). We show, for the constant noise model, that singularities exist when exact values of d' are computed and that the singularities are not limited to steep psychometric functions. In these cases the disambiguation of the different models requires millions of trials.     

益气复脉汤对脑缺血再灌注损伤大鼠ET及CGRP影响的实验研究

目的：观察益气复脉汤对脑缺血再灌注模型大鼠血浆内皮素（ET）和降钙素基因相关肽（CGRP）含量变化的影响，探讨大鼠脑缺血再灌注损伤的中医药治疗方法。方法：采用线栓法制备大鼠右侧大脑中动脉脑缺血再灌注损伤模型，分别用益气复脉汤高、低剂量组、尼莫地平水溶液予以治疗，然后采用放射免疫法检测血清ET和CGRP含量。结果：模型组脑缺血再灌注大鼠血浆ET含量明显增高，而CGRP下降，治疗后ET值比对照组下降明显（P〈0．01），CGRP值比对照组增高明显（P〈0．05）。结论：益气复脉汤通过降低ET和增高CGRP，能够对脑缺血再灌注损伤脑起保护作用，其疗效优于尼莫地平。     

调脂宜从肝脾入手

中医学认为血脂异常在病机方面属“痰浊”、“血瘀”范畴，生理上与中医之膏脂相类似，属津液之范畴，肝脾功能的正常是血脂正常代谢的重要条件，脾“化”的相对不足是血脂代谢异常的根本原因；肝失疏泄是血脂代谢失常的重要因素，治疗的根本在于截断血脂失调的源头，或者扭转已有的病理趋势，使其不再发生代谢紊乱。
